How Much Does It Cost to Replace Internal Doors in the UK in 2026? Fire Doors, Ironmongery and Labour Explained
If you have ever tried to shut a bedroom door only for it to catch on the carpet, rattle in the frame, or refuse to latch properly, you have already experienced why replacement becomes unavoidable. In 2026, the cost to replace internal doors in the UK for a typical three bedroom house can range from around £1,200 for basic upgrades to over £4,000 once fire doors, new linings, and finishing are factored in. What looks like a straightforward swap often turns into a detailed carpentry job involving precise fitting, compliant hardware, and adjustments to older openings.
The cost to replace internal doors in the UK in 2026 varies widely depending on door type, materials, fire safety requirements, and labour. Most homeowners will spend between £120 and £450 per door fully fitted, but that range can climb quickly if you are upgrading to fire doors, adjusting frames, or fitting premium ironmongery. This guide breaks down real world costs, what affects them, and what tradespeople actually look for on site.
This is not just about swapping one slab for another. Internal doors interact with frames, linings, hinges, latches, fire safety rules, and even escape routes. Done properly, they improve safety, acoustics and the overall feel of your home. Done badly, they bind, drag, fail fire compliance checks and cost more to put right.
Average cost to replace internal doors in the UK
For a straightforward like for like replacement in an existing frame, here is what most homeowners pay in 2026.
| Type of Door | Supply Cost | Labour Cost | Total per Door |
|---|---|---|---|
| Hollow moulded door | £35 to £70 | £70 to £120 | £120 to £190 |
| Solid core door | £70 to £150 | £80 to £140 | £150 to £290 |
| Solid oak or hardwood door | £150 to £350 | £100 to £180 | £250 to £530 |
| Glazed internal door | £120 to £300 | £100 to £180 | £220 to £480 |
| FD30 fire door | £90 to £250 | £120 to £220 | £210 to £470 |
These figures assume the door lining is usable, no major alterations are needed, and standard handles and hinges are fitted. Costs rise if there is warping, out of square openings, or older properties where nothing is standard size.
Regional variation also matters. In London and the South East, labour per door is commonly £20 to £50 higher due to day rates, parking charges and congestion costs. In parts of the North or Wales, pricing tends to sit at the lower end of the ranges shown. However, complex work such as fire door installation is priced more consistently across the UK because the level of skill and compliance required is the same.
What Affects the Cost of Replacing Internal Doors
Tradespeople price internal doors based on time, accuracy, and risk. Hanging a door is not complex in theory, but achieving tight margins and smooth operation across several openings takes experience.
Door Size and Fit
Standard UK internal doors are typically 1981 by 762 millimetres for modern homes, but many properties, especially pre 1980s, deviate. Victorian and Edwardian homes often have taller openings or non standard widths. In these cases, doors may need to be heavily trimmed or custom ordered, which increases both supply and labour costs.
Fire doors add another constraint. Manufacturers limit how much can be trimmed, often no more than 3 to 6 millimetres per edge. If your opening is significantly out, the only compliant option may be resizing the lining rather than the door.
Condition of the Door Lining
If the lining is twisted, split, or badly out of square, a simple replacement becomes a structural adjustment job. Carpenters often find older softwood linings that have moved over time due to settlement or repeated repainting.
Minor issues can be corrected by packing hinges or planing the door. More severe cases require partial rebuilds or full lining replacement, typically costing £120 to £250 extra per opening including materials.
Full replacement is usually unavoidable where:
- The opening is significantly out of square
- The lining is damaged by previous fixings or rot
- Fire door upgrades require compatible certified frames
- Floor levels have changed, leaving large gaps at the bottom

Ironmongery and Accessories
Handles, hinges, latches, locks and stops all add cost. Cheap sets might cost £15 per door, while quality brushed steel handles with fire rated hardware can exceed £60.
Fire Safety Requirements
Fire doors require certified components, intumescent seals, and precise fitting. Labour is higher because tolerances matter. More on that shortly.
Finishing
Unfinished doors need painting, staining or oiling. This adds £50 to £120 per door depending on coats and products.
Access, parking and disposal
In urban areas, tradespeople often factor in parking permits, congestion charges, and carrying materials through restricted access. These can add £20 to £80 per day. Disposal of old doors is typically £30 to £70 depending on quantity and waste carrier fees.
Acoustic performance and insulation
Door type also affects sound and heat retention. Hollow doors are lightweight and cheaper but transmit sound easily. Solid core doors offer noticeably better noise reduction, often used between living areas and bedrooms. Fire doors provide the best density and acoustic performance, which is useful in busy households. Upgrading for acoustic reasons can justify higher upfront costs.
Additional Costs to Budget For
| Item | Typical Cost | Notes |
|---|---|---|
| Frame or lining repair | £50 to £150 per door | Minor packing, filling or realignment |
| Full lining replacement | £120 to £250 per door | Required for badly damaged or out of square openings |
| Painting and finishing | £50 to £120 per door | Depends on coats and drying time |
| Fire door certification | £10 to £40 per door | Labelling, documentation or inspection |
| Waste removal | £30 to £70 total | Varies by volume and location |
Fire Doors and Building Regulations
Fire doors are not optional in certain situations. If you are replacing doors in a property with three storeys, or doing a loft conversion, Building Regulations Approved Document B applies. These doors form part of the escape strategy.
Typical requirements include:
- FD30 doors offering 30 minutes fire resistance
- Intumescent strips and sometimes smoke seals
- Fire rated hinges, usually three per door
- Certified FD rated door leaf and compatible frame
You can read the official UK guidance here: Approved Document B Fire Safety.
Installations should follow BS 8214, which is the code of practice for fire door assemblies. Many compliant products are tested under certification schemes such as Certifire or BM TRADA, both of which provide traceable performance data and installation guidance. See BM TRADA for more on third party certification.
Many homeowners underestimate how strict these installations are. Gaps must usually be 2 to 4 millimetres at the sides and top, and slightly larger at the bottom depending on flooring and ventilation needs. If the gaps are too large, the door fails compliance.
Building Control sign off is typically required where fire doors are part of a larger project such as a loft conversion or change of use. For like for like replacements in existing compliant layouts, formal approval may not be required, but installations still need to meet standards.
Planning permission vs Building Regulations
Planning permission is rarely needed for internal door changes, as these are not considered external alterations. Building Regulations can still apply, especially where fire safety, escape routes, or structural openings are affected. This distinction catches many homeowners out.

Cost of Fire Door Installation
Fitting a fire door typically costs more because:
- More precise cutting and fitting
- Additional hardware such as seals and closers
- Potential inspection requirements
Expect £120 to £220 labour per fire door, compared to £70 to £120 for a standard internal door.
Ironmongery Costs Explained
Ironmongery is often overlooked, but it can significantly influence both price and performance.
Typical Price Ranges
| Grade | Cost per Door | Durability | Typical Use |
|---|---|---|---|
| Budget | £15 to £30 | Low to moderate | Rental properties or low traffic rooms |
| Mid range | £30 to £60 | Good | Most residential homes |
| Premium | £60 to £120 | High | High traffic areas or design focused interiors |
Cheaper hinges and latches tend to wear quickly, leading to misalignment and sticking doors. It is rarely worth cutting costs here.

Labour Costs and Timeframes
A skilled carpenter can usually hang:
- 4 to 6 standard internal doors in a day
- 2 to 4 fire doors in a day depending on complexity
Day rates in 2026 typically range from £200 to £350 depending on region. London and the South East will sit at the higher end.
Per door pricing is common for small jobs, but larger projects are usually quoted on a day rate basis. For example, six standard doors in one property might cost £300 to £600 labour total, while the same six doors priced individually could be higher.
Full house replacements are typically staged over 2 to 4 days depending on size. Tradespeople often remove and hang doors room by room to keep the property usable, especially in occupied homes. Bedrooms are often done first, followed by living areas and then final adjustments.
Expect disruption in the form of noise, dust, and limited access to rooms during fitting. Doors may be removed for several hours at a time. Painting or finishing can extend the timeline by an additional 1 to 2 days due to drying times.
Common site issues include uneven floors affecting clearances, plasterboard movement causing tight openings, and old hinge positions that no longer align. These slow the process and sometimes require revisits.
Labour includes:
- Removing old doors
- Trimming and fitting new doors
- Installing hinges and latches
- Adjusting for smooth operation
It may not include painting or disposal of old doors, which are often charged separately.
Replacing Multiple Doors
If you are replacing all internal doors in a property, costs per door often drop slightly due to efficiency.
Typical full house costs:
- 2 bedroom house, £800 to £2,000
- 3 bedroom house, £1,200 to £3,000
- 4 bedroom house, £1,800 to £4,500
This assumes 6 to 10 doors. Larger properties or premium materials will increase the total.
Bulk savings and homeowner preparation
Cost savings usually come from reduced setup time and consistent working conditions. Carpenters can set up once and move efficiently between openings.
You can help reduce labour time by:
- Clearing rooms and access routes in advance
- Ensuring all doors, hinges and handles are on site before work starts
- Confirming door handing and swing direction ahead of time
- Removing old carpets where they interfere with clearance
Even small delays such as missing hinges can add hours to a job, especially if tradespeople need to leave site to source parts.
DIY vs Hiring a Professional
DIY door hanging is possible, but it is not as forgiving as it looks. Achieving even gaps, correct hinge depth, and accurate latch alignment requires precision tools and experience.
Risks of DIY include:
- Uneven gaps and poor closing action
- Damage to door edges during trimming
- Incorrect hinge positioning leading to sagging
- Non compliant fire door installation
Professional carpenters use routers, jigs, and laser levels to achieve consistent results. Fire doors in particular should not be installed DIY due to certification and safety requirements.
DIY is more suitable for replacing like for like doors in good condition frames, using pre finished doors with minimal adjustments.
Loft Conversions and Fire Door Requirements
A loft conversion often triggers mandatory upgrades to existing doors. This catches many homeowners off guard.
If your loft becomes a habitable room, you may need:
- Fire doors on all rooms opening onto the stairwell
- Linked smoke alarms
- Protected escape routes
Detailed guidance is covered here: Loft Conversion Fire Safety Explained Escape Routes Doors and Alarms for Homeowners.
This can turn a simple door upgrade into a wider fire safety project costing several thousand pounds.
Practical Checklist Before Replacing Internal Doors
- Pre installation
- Measure every door opening individually, including height, width and depth
- Check floor levels and planned floor finishes
- Inspect linings for square and structural soundness
- Confirm whether fire doors are required
- Order doors, hinges and handles together to ensure compatibility
- During installation
- Verify door swing direction before cutting
- Maintain consistent gaps on all edges
- Check latch alignment before final fixing
- Test smooth opening and closing repeatedly
- Post installation
- Apply appropriate finishes or paint
- Recheck hinges and handles after 1 to 2 weeks of use
- Keep certification documents for fire doors
Common Mistakes to Avoid
Ordering the Wrong Size Doors
Trimming allowances are limited, especially on fire doors. Too much trimming voids certification and can render the door unusable.
Ignoring the Frame or Lining
Fitting a new door into a poor frame leads to ongoing issues like sticking, uneven gaps, and latch failure. In many older homes, frames are the biggest hidden cost.
Using Non Compliant Hardware on Fire Doors
All components must be rated. Mixing standard hinges with a fire door is not acceptable and can invalidate insurance.
Poor Gap Control
Even small deviations become obvious. Experienced carpenters aim for consistent margins across all doors in a property, not just one.
Underestimating Finishing Costs
Painting multiple doors properly takes time. Each coat requires drying and light sanding for a professional finish.
Not accounting for real site conditions
Uneven floors, swelling timber, and previous poor installations often complicate jobs. Assuming a simple swap without inspection leads to under budgeting.
Standards and Safety Guidance
For safety and compliance, tradespeople follow recognised standards and guidance such as:
- UK Building Regulations Approved Document B
- BS 8214 Code of practice for fire door assemblies
- Guidance from the Health and Safety Executive
- Third party certification such as BM TRADA and Certifire
Certification matters for insurance, resale, and safety. Always ask for details if fire doors are being installed.
FAQ
How much does it cost to replace all internal doors in a 3 bed house?
Most homeowners spend between £1,200 and £3,000 depending on the door type and how much remedial work is needed. If fire doors are required throughout, or if several linings need replacing, costs can rise to £3,500 or more. The best way to control costs is to confirm sizes and lining condition before ordering materials.
Do I need fire doors in a two storey house?
Usually no, unless major alterations are made. However, adding a loft conversion or creating open plan layouts that affect escape routes may trigger requirements. Always check with Building Control if you are unsure, as retrospective upgrades can be more expensive.
Can I replace internal doors myself?
You can, but achieving a professional finish is difficult without the right tools. Fire doors should always be installed by experienced tradespeople. Even small installation errors can invalidate ratings.
How long does it take to replace a door?
A standard door takes 1 to 2 hours for an experienced carpenter. Fire doors or problematic openings can take 2 to 4 hours each due to precise fitting and sealing requirements.
Is it cheaper to just replace door handles instead of doors?
Yes, significantly. Replacing handles costs £20 to £80 per door. However, if doors are warped, damaged, or poorly fitted, new handles will not solve the underlying issue.
Do internal doors add value to a property in the UK?
Yes, particularly when replacing outdated or damaged doors with consistent, well fitted alternatives. Estate agents often highlight modern interiors, and matching doors throughout a property improve first impressions. While the financial return varies, upgraded doors can make a home easier to sell and more appealing to buyers.
How do I choose the right internal door style for my home?
Match the door style to the age and character of your property. Panelled doors suit period homes, while flush or glazed designs fit modern interiors. Consider light flow, privacy, and acoustics. Solid core doors are better for bedrooms, while glazed doors help brighten darker hallways.
Final Thoughts
Replacing internal doors is one of the most effective ways to refresh a home, but the real cost depends on more than just the door itself. Frames, ironmongery, fire safety and skilled labour all play a part. Cutting corners often leads to doors that never quite shut properly or fail basic safety expectations.
