Renovation Schedule Of Works

A clear renovation schedule of works is the backbone of any successful UK home improvement project. Without one, trades overlap, materials arrive late, inspections get missed, and costs creep. With one, each stage follows in the right order, trades know when they are needed, and you can manage cash flow and compliance with confidence. This guide sets out how a proper schedule of works is built in practice, what it should contain, typical timeframes and costs across the UK, and how to keep it on track from strip out to final sign off.

What a renovation schedule of works actually is

A schedule of works is a structured, ordered list of every task required to complete your project, grouped by phase and aligned to a realistic timeline. It is not a wish list. It is a working document that builders, electricians, plumbers and specialist contractors can follow on site.

On most UK renovations, the schedule sits alongside your drawings and your scope of works. The drawings show what is being built. The scope describes the detail and quality. The schedule sets the order and timing.

If you need a deeper look at how to create a programme that trades will respect, this article is worth reading: How to Create a UK Home Renovation Programme of Works That Tradespeople Actually Follow. It complements the schedule of works by focusing on sequencing and accountability.

Why sequencing matters on UK sites

Renovation work is interdependent. You cannot plaster before first fix electrics. You should not install a kitchen before the plumbing has been tested and the service positions have been checked against the kitchen plan. Get the order wrong and you pay twice.

Sequencing also ties directly into Building Regulations. For example, structural alterations under Part A must be inspected at key stages. Electrical work under Part P needs appropriate testing, certification and, where applicable, notification by a competent person scheme member such as NICEIC. Gas work must be carried out by a Gas Safe registered engineer. Skipping or mistiming these checks can lead to failed inspections and rework.

Approved Documents are available via the UK Government planning portal here: https://www.planningportal.co.uk/permission/building-regulations. On site, the practical point is to book inspections in advance and align them with your schedule.

Typical phases in a renovation schedule of works

Every project is different, but most house renovations in the UK follow a consistent order. Below is a practical breakdown you can adapt.

• Pre start: Complete surveys, design work, structural calculations and party wall notices where required.
• Site setup and protection: Arrange skips, welfare facilities, floor protection and temporary services.
• Strip out and demolition: Remove agreed finishes, fittings and non structural elements.
• Structural works: Install steels, form loadbearing alterations and construct foundations for extensions.
• First fix: Install electrical back boxes, cable routes, lighting point wiring, plumbing, heating, audiovisual cables and data cabling.
• Insulation and airtightness: Fit specified insulation and seal relevant junctions before surfaces are closed.
• Windows and external doors: Make the building secure and weather resistant.
• Plastering and drylining: Board, prepare and finish walls and ceilings.
• Second fix: Complete joinery, plumbing fixtures, sanitaryware and internal fittings, then fit electrical accessories and light fittings at the appropriate finishing stage.
• Kitchen and fitted furniture: Install units, worktops and associated fittings.
• Decoration: Prepare surfaces and apply the specified paint or wall finishes.
• Floor finishes: Lay timber, carpet, vinyl, laminate, stone or tiles as specified.
• External works and landscaping: Complete drainage finishes, paving, fencing and planting.
• Testing, certification and sign off: Test services, complete snagging and obtain final approvals and certificates.

Where homeowners often struggle is defining each task in enough detail so that quotes line up.

Understanding the critical path

The critical path is the chain of tasks that controls the earliest possible completion date. A delay to any task on this path moves the whole project unless lost time can be recovered elsewhere.

For an extension, the critical path commonly runs through excavation, foundations, drainage, structural walls, roof construction, weatherproofing, first fix services, plastering, kitchen installation and final service connections. Decorating a spare room may have some flexibility. Waiting for a structural steel, roof covering or bespoke door usually does not.

Mark critical tasks clearly in the programme and give each one a responsible person, start date, finish date and confirmed prerequisite. Review them every week. A task reported as 90 per cent complete can still prevent the next trade from starting, so progress should be measured by whether the area is genuinely ready to hand over.

Float is the spare time available before a task affects the completion date. Use float deliberately rather than treating it as unused time. Weather dependent groundworks, specialist fabrication and work requiring an inspection usually deserve more allowance than straightforward decoration.

Mapping task dependencies

Dependencies explain what must happen before another activity can start. Recording them prevents a programme from becoming a list of optimistic dates with no practical connection between tasks.

• Structural dependency: Temporary supports and approved details must be in place before a loadbearing wall is removed.
• Inspection dependency: Building Control may need to inspect reinforcement, drainage or insulation before it is covered.
• Service dependency: Electrical and plumbing first fix must be complete before walls and ceilings are boarded.
• Measurement dependency: Worktops can usually be templated only after base units are fixed, level and in their final positions.
• Drying dependency: Screed, plaster, paint and tile adhesive need suitable curing or drying time before later finishes are applied.
• Procurement dependency: Installation cannot begin until the correct products, fixings and accessories have arrived and been checked.

Ask each trade what they need from the previous trade and what condition they must leave for the next one. This simple handover check catches missing noggins, incorrect pipe positions, unsupported back boxes and unsuitable surfaces before they become expensive problems.

Realistic timelines for common UK renovation projects

Timeframes depend on access, complexity, and how well coordinated your trades are. The ranges below reflect typical UK jobs with a competent builder and no major surprises.

Project type	Typical duration	Notes
Bathroom refurb	2 to 4 weeks	Allow longer if pipework is moved or structural floors need repair.
Kitchen refurb	3 to 6 weeks	Allow time for worktop templating and manufacture.
Full house cosmetic refurb	6 to 12 weeks	This assumes no major structural changes.
Single storey extension	10 to 16 weeks	Weather and ground conditions can affect the early stages.
Loft conversion	8 to 14 weeks	Scaffolding and roof works commonly sit on the critical path.
Full renovation with rewiring and replumbing	12 to 24 weeks	Duration varies with property size, condition and specification.

Lead times for trades and materials can add weeks before you even start. Kitchens can take 4 to 10 weeks from order. Windows and doors often take 6 to 12 weeks. Book early and align deliveries to your schedule.

Sample week by week renovation programme

The example below shows a straightforward 16 week programme for a ground floor renovation with internal structural alterations, a new kitchen, a small WC and replacement finishes. It assumes permissions, structural design and party wall matters have already been resolved. Larger extensions and homes with extensive defects will need longer.

Week	Main activities	Checks and dependencies
1	Set up the site, protect retained areas, isolate services and complete the agreed strip out.	Confirm the demolition scope and check for hidden defects or suspect materials.
2	Install temporary supports, form openings and begin structural alterations.	Follow the engineer's details and arrange required Building Control inspections.
3	Install steels, complete masonry alterations and make good structural areas.	Confirm bearing details, fire protection requirements and final room dimensions.
4	Alter drainage, prepare floors and complete any external openings.	Inspect drainage before covering and verify kitchen service positions.
5	Complete electrical first fix, including back boxes, cable routes and lighting point wiring.	Check socket, switch, appliance and lighting positions against the approved layouts.
6	Complete plumbing and heating first fix, then test concealed pipework.	Resolve leaks and photograph service routes before closing surfaces.
7	Fit insulation, complete airtightness details and install plasterboard.	Obtain any required inspection before insulation or services are concealed.
8	Plaster walls and ceilings.	Provide ventilation and suitable background heat without forcing the drying process.
9	Allow plaster to dry, complete minor repairs and apply a suitable mist coat where ready.	Check moisture conditions before full decoration or sensitive floor finishes.
10	Install kitchen base and wall units and complete second fix carpentry.	Check units are level and ready before worktop templating.
11	Template worktops, fit sanitaryware and complete accessible plumbing connections.	Retest plumbing and protect fitted units.
12	Continue decoration and prepare floors.	Confirm subfloor levels, moisture readings and product acclimatisation requirements.
13	Fit worktops, sinks and splashbacks.	Allow adhesives and sealants to cure before heavy use.
14	Fit sockets, switches and light fittings, then connect fixed appliances.	The electrician tests the installation and deals with any faults.
15	Lay finished flooring and complete final decoration.	Protect finished surfaces and restrict unnecessary site traffic.
16	Complete testing, certification, snagging, cleaning and handover.	Obtain Building Control sign off and agree dates for any remaining snagging.

This programme should be treated as a planning model rather than a promise. Bespoke worktops may require more than one week after templating, and structural discoveries can affect several later activities. Update the dates as soon as confirmed information changes.

Cost breakdown by phase

Costs vary widely by region and specification, but a schedule of works helps you allocate budget across phases and manage cash flow. The ranges below are indicative for 2026 UK projects.

• Pre construction costs: Allow 5 to 10 per cent of the build cost, including design, structural engineering and planning work where applicable.
• Demolition and strip out: Allow £1,500 to £5,000 for a typical house, with more required for controlled asbestos removal.
• Structural works: Allow £5,000 to £40,000. Individual steels often cost £1,500 to £3,500 each when supplied and installed, subject to size and access.
• First fix electrics: Allow £2,500 to £6,000 as part of an average house rewire, depending on the number of circuits and points.
• First fix plumbing and heating: Allow £4,000 to £12,000, depending on the system design and boiler changes.
• Windows and doors: Allow £6,000 to £20,000, depending on property size, material and specification.
• Plastering: Allow £2,000 to £8,000, depending on area, access and the condition of the existing surfaces.
• Second fix: Allow £3,000 to £10,000 for joinery, sanitaryware fitting and service finishes, excluding kitchen supply.
• Kitchen supply and installation: Allow £7,000 to £30,000 or more.
• Decoration: Allow £2,000 to £7,000.
• Flooring: Allow £2,000 to £10,000, depending on preparation and materials.
• Contingency: Allow 10 to 15 per cent on older properties.

Cash flow follows the schedule. Trades usually stage payments at key milestones, for example after first fix or plastering. Avoid large upfront payments. Agree payment points in writing.

Setting fair milestone payments

Milestone payments should reflect measurable progress and the value of work properly completed. Dates alone are a poor basis for payment because a delayed or incomplete stage may not justify the amount requested.

A typical arrangement might include a modest deposit for mobilisation, followed by payments after structural work, first fix, plastering, installation of major fittings and practical completion. The exact percentages depend on the contract, procurement route and materials being purchased.

• Define each milestone: State precisely what must be completed, inspected and accepted before payment becomes due.
• Separate materials where sensible: For expensive bespoke items, request an invoice, proof of order and confirmation of ownership before paying.
• Check progress: Compare the payment request with the schedule, site condition and agreed variations.
• Retain a final balance: Keep an agreed sum until practical completion, certificates and the main snagging items have been dealt with, subject to your contract.
• Record every payment: Keep invoices, receipts and a running total against the contract sum and contingency.

Do not use the contingency to cover ordinary items omitted from an unclear quote. It is intended for genuine unknowns and approved changes. Payment terms, deposit protection where relevant, ownership of unfixed materials and procedures for disputes should be recorded in the building contract.

A practical checklist for building your schedule

• Start with drawings and structural calculations that are ready for construction.
• List every task by phase, then by room where helpful.
• Place tasks in the correct order and check dependencies between trades.
• Add realistic durations based on project type, access and available labour.
• Insert inspection points for Building Control.
• Add procurement tasks and lead times for long lead items.
• Assign each task to a named trade or contractor.
• Build in float for delays, especially for weather sensitive work.
• Circulate the draft to your main contractor and key trades for a practical review.
• Agree the baseline programme and track changes as the job progresses.

Integrating Building Regulations into your schedule

Compliance is not a single event at the end. It runs through the entire schedule. Coordinate these checkpoints:

• Arrange foundation and drainage inspections for extensions before the relevant work is covered.
• Complete structural steel installation checks under Part A at the agreed stage.
• Inspect insulation and airtightness measures under Part L before closing up.
• Arrange electrical testing, certification and any required Part P notification through a suitably qualified electrician, such as a scheme member listed by https://www.niceic.com.
• Use a registered engineer for gas work and verify registration through https://www.gassaferegister.co.uk.
• Obtain the final completion certificate from Building Control.

Book inspections at least a few days ahead. Missed inspections often mean opening up finished work, which is expensive and disruptive.

Programming trades to avoid clashes

On most sites, clashes waste more time than anything else. A plasterer cannot work efficiently around multiple trades. A kitchen fitter needs a clean, dry, finished space with services correctly positioned.

Keep these rules in your schedule:

• Allocate one trade per area during critical phases such as plastering and kitchen installation.
• Allow proper drying times. Plaster typically needs several days before decoration and may need longer in winter.
• Complete first fix, then inspection and closing up, followed by finishing work and final service connections.
• Separate noisy or dusty work from finishing trades.
• Plan access routes and storage so materials do not block work areas.

Procurement and lead times

Your schedule should include ordering dates, delivery windows and checks on site. Common long lead items include kitchens, windows, bifold doors, tiles from specific ranges and bespoke joinery.

Set order dates backwards from installation dates. Confirm sizes from site measurements, not drawings, before placing final orders. Keep a log of delivery dates and inspect goods on arrival. Damaged items discovered late can stall the programme.

A useful procurement tracker should include the item, supplier, specification, quantity, approval date, order date, required delivery date, confirmed delivery date, payment status and storage location. Add the person responsible for chasing each order.

Item	Typical planning allowance	Required checks
Kitchen units	4 to 10 weeks	Confirm final layout, finishes, appliance sizes and service positions.
Windows and external doors	6 to 12 weeks	Use verified opening sizes and confirm glazing, ventilation and safety requirements.
Bespoke joinery	6 to 12 weeks	Approve detailed drawings, finishes, ironmongery and access arrangements.
Tiles and flooring	2 to 6 weeks	Check batch numbers, wastage, trims, adhesives and suitable substrates.
Worktops	1 to 4 weeks after templating	Confirm sink, tap, hob, joints, edge details and access for installation.

Do not arrange deliveries simply because space appears available in the programme. Confirm that the site is secure, dry and able to store the goods without damage. Kitchens, timber flooring and sanitaryware delivered too early can obstruct trades or be exposed to moisture and impact damage.

Controlling changes during the build

Changes are common, but informal instructions cause confusion over cost, responsibility and completion dates. Use a written change control process, even on a modest renovation.

Before approving a variation, ask for a description of the change, the reason, the added or reduced cost, any effect on the programme and any design or Building Regulations implications. The builder should not proceed until the change is authorised, except where immediate work is needed to make the site safe.

• Record the request: Give each proposed change a reference number and date.
• Assess the impact: Check labour, materials, waste, specialist design, inspections and delay.
• Approve in writing: Record the agreed cost and revised completion date before work starts.
• Update the documents: Amend the scope, drawings, procurement tracker, budget and live programme.
• Close the change: Confirm completion and include it in the next appropriate payment assessment.

A seemingly small decision, such as moving a sink, can affect drainage falls, cabinets, worktop openings, electrical zones and floor finishes. Assess the whole chain rather than pricing only the visible task.

What can go wrong and how to prevent it

Even well planned jobs encounter issues. The goal is to reduce the impact.

• Hidden defects: Rotten joists, outdated wiring and asbestos can stop work. Use surveys where practical and maintain a contingency budget.
• Poorly specified work: Missing details lead to variations and delays. Agree a detailed scope and suitable drawings before starting.
• Poor coordination: Trades can arrive in the wrong order. Maintain a live schedule shared with all relevant parties.
• Late materials: Delayed windows or kitchens can hold up dependent work. Order early and obtain confirmed delivery windows.
• Weather delays: Rain can affect groundworks and roofing. Plan for the season and include float in the programme.
• Failed inspections: Non compliant work can require opening up and correction. Use qualified trades and book inspections in line with the schedule.
• Cash flow issues: Payments may become disconnected from progress. Use staged payments linked to defined milestones.

Example of a simple room by room sequence

For a typical ground floor renovation including a kitchen and WC, a practical sequence looks like this:

• Strip out the kitchen and remove the agreed flooring.
• Alter walls and install steels where required.
• Complete electrical first fix, including back boxes, cable routes, circuit wiring and preparation for lighting points.
• Complete plumbing and heating first fix, including water, waste and heating routes.
• Test concealed pipework and inspect first fix services before closing up.
• Install insulation and close the walls and ceilings with plasterboard.
• Apply the plaster skim and allow it to dry properly.
• Apply a suitable mist coat and complete the required early decoration.
• Install kitchen units once the room is dry and the service positions have been checked.
• Template and fit the worktops.
• Complete second fix plumbing, fit sanitaryware and test the completed connections.
• Tile the splashbacks and allow adhesives and grout to cure.
• Fit sockets, switches and light fittings, connect fixed appliances, then test and certify the electrical installation.
• Lay the finished flooring at the appropriate stage for the selected product and kitchen design.
• Complete snagging and carry out the final clean.

This order avoids overlap between electrical first fix and final fitting. Back boxes, cable routes and lighting point wiring are installed before plastering. Sockets, switches, light fittings and appliance connections are fitted once surfaces and fixed furniture are ready, followed by testing and certification.

The sequence also avoids damage to finished surfaces and keeps access clear for each trade.

Managing the schedule during the build

A schedule of works is not static. Update it weekly. Mark completed tasks, shift dates where needed, and communicate changes to all trades.

Site meetings every one to two weeks work well on most projects. Review progress against the plan, confirm upcoming trades, and check materials are on hand. Keep notes and share them the same day.

Use a short planning window for detailed coordination. At each meeting, review the next two or three weeks task by task. Confirm labour, information, materials, access, inspections and the condition of preceding work. This gives enough warning to solve problems without trying to predict every small site decision months ahead.

For larger projects, a simple Gantt chart helps visualise overlaps and critical path items. Even on smaller jobs, a clear list with dates is far better than relying on memory.

Quality control and sign off

Build quality is easier to secure when checks are built into the schedule. Agree hold points, for example before plastering to inspect first fix, or before tiling to confirm substrate and layout.

Snagging should not be left to the end alone. Capture issues as you go. At practical completion, create a final snag list and agree a timeframe for rectification.

Final documentation should include electrical and gas certificates, any warranties, instruction manuals, and the Building Control completion certificate. Without these, selling or remortgaging can be problematic.

FAQ

How detailed should a renovation schedule of works be?

Detailed enough that a competent trade can pick up a task and know exactly what is expected, where, and when. At minimum, each task should have a clear description, location, duration, dependencies, and a named trade. For complex elements, reference drawings and specifications. Vague entries like “fit kitchen” are not sufficient. Break it into delivery, dry fit, worktop templating, final fit, and connections.

Do I need planning permission before creating a schedule?

You can draft a schedule early, but do not fix the construction start date until the necessary consents and any pre commencement conditions are dealt with.

Purely internal alterations commonly do not require planning permission, provided they do not materially affect the external appearance or amount to a change of use. Building Regulations approval may still be required for structural work, drainage, fire safety, insulation and controlled services.

Extensions and external alterations may fall within permitted development rights or may require a planning application. The position depends on the property's location, dimensions, previous alterations and local restrictions. Permitted development rights can also be limited or removed by planning conditions or an Article 4 direction.

Listed buildings may require listed building consent for internal as well as external work. Properties in conservation areas can be subject to tighter controls, particularly for demolition, windows, roofs and visible external changes. Check the planning portal guidance here: https://www.planningportal.co.uk/permission and confirm uncertain cases with your local planning authority. Planning permission, listed building consent and Building Regulations approval are separate requirements.

Who is responsible for the schedule, me or the builder?

On a main contractor project, the builder typically produces and manages the programme, aligned to your contract. On smaller or multi trade jobs, the homeowner often coordinates the schedule. Even with a builder, you should review and understand the sequence and key dates. Shared visibility reduces disputes and delays.

How do I factor in inspections and certifications?

Add them as tasks with dates and dependencies. For example, book Building Control to inspect foundations before later work covers them, and arrange an insulation inspection before closing walls where requested. Electrical and gas work should be carried out, tested and certified by appropriately qualified professionals. Keep copies of certificates and link them to the relevant stages in your schedule.

What contingency should I allow in time and budget?

For older properties, allow 10 to 20 per cent extra time and 10 to 15 per cent in budget. Unknowns are common once you open up floors and walls. Even on newer homes, small delays accumulate. A sensible amount of float prevents a minor issue from derailing the entire project.

Final Thoughts

A well structured renovation schedule of works turns a complex project into a controlled process. It aligns trades, keeps materials flowing, and ties compliance checks to the right moments. Invest the time to plan it properly, keep it live during the build, and use it to hold everyone accountable to dates and standards.
