These ranges combine standard and premium installations. The lowest figures generally apply to standard-sized doors fitted into sound existing openings, while bespoke products and complex installations fall towards the upper end.

​

​

UPVC Door Installation Costs

 

UPVC doors are normally the least expensive external door option. A standard white UPVC front or back door will typically cost approximately £825 to £1,500 supplied and fitted.

​

Prices increase when the door includes:

​

• Decorative or obscure glazing

• Side panels or a glazed fanlight

• Woodgrain or coloured finishes

• Different colours internally and externally

• Upgraded handles and locks

• Low or accessible thresholds

• Bespoke dimensions

​

UPVC doors can provide a practical, relatively low-maintenance solution for front entrances, back doors and utility rooms. However, the frame profiles are usually wider than aluminium, and the design options may not suit every period property.

​

​

Composite Door Installation Costs

 

Composite doors are among the most popular choices for replacement front doors. They combine an insulated door slab with a reinforced frame, weather seals and multi-point locking.

​

A standard composite front door may cost between approximately £1,100 and £2,000 fitted. Higher-specification doors with thicker slabs, premium finishes, specialist glazing and upgraded security hardware can cost £2,500 to £4,500 or more.

​

The final cost will depend on the manufacturer and the complete doorset specification. Homeowners should check whether the quotation includes the frame, threshold, handles, locks, glazing, installation and disposal of the existing door.

​

A low supply-only price cannot be compared directly with a bespoke fitted doorset that includes surveying, installation, certification and a guarantee.

​

​

Timber Door Installation Costs

 

Timber doors can suit traditional, period and listed properties where natural materials and authentic detailing are important.

​

A relatively simple timber entrance door may start from around £1,500 supplied and fitted, while bespoke hardwood or engineered timber doors can cost £3,000 to £5,000 or more.

​

The price may increase where the installation includes:

​

• A bespoke timber frame

• Decorative glazing

• Side or top lights

• Traditional mouldings

• Specialist ironmongery

• Factory painting

• Hardwood construction

• Heritage or conservation detailing

​

Timber doors also require periodic maintenance. The frame, joints and lower edge of the door must remain properly protected against moisture to avoid swelling, decay and deterioration.

​

Some national suppliers quote considerably higher prices for fully bespoke hardwood doorsets, demonstrating why the specification must be examined rather than relying on a single headline figure.

​

​

Aluminium Door Installation Costs

 

Aluminium doors offer slim profiles, strength and a contemporary appearance. They are commonly used for modern front doors, glazed entrance doors and large patio-door systems.

​

A single aluminium entrance door may cost approximately £1,800 to £4,000 or more, depending on its size, glazing and security specification.

​

Aluminium is generally more expensive than UPVC but can provide:

​

• Slimmer frames

• Larger glazed areas

• Durable powder-coated finishes

• Strong frames for wider openings

• Matching windows and patio doors

• Contemporary colour options

​

Bespoke colours, oversized doors, pivot systems and concealed hardware can increase the price substantially.

​

​

Front Door Installation Costs

 

Replacing a front door in an existing opening is normally less expensive than altering the size or position of the entrance.

​

A typical fitted front door may cost between £825 and £3,000, depending on whether it is UPVC, composite, timber or aluminium. Premium bespoke installations can exceed this range.

​

The labour element for fitting a new front door is commonly estimated at between £200 and £1,000, depending on the complexity of the work, although most homeowners purchase the door and installation as one package.

​

The quotation should confirm whether the price includes:

​

• Removing the existing door and frame

• Supplying the complete new doorset

• New handles and security hardware

• Internal trims and making good

• External sealing

• Disposal of the old door

• Certification where required

​

​

Back Door Installation Costs

 

Back doors are often less decorative than front doors, although they must still provide suitable security, thermal performance and weather protection.

​

A standard UPVC back door may cost approximately £825 to £1,500 fitted. A composite back door will generally cost around £1,100 to £2,500, depending on the style and specification.

​

Half-glazed and fully glazed doors may require toughened or laminated safety glass. Integrated blinds, decorative glazing and pet doors can also add to the price.

​

Where the kitchen or utility room floor is close to external ground level, the threshold and weathering details should be carefully considered. A low threshold can improve accessibility but must still prevent water penetration.

​

​

French Door Installation Costs

 

French doors consist of two hinged doors that open from the centre. They are commonly used between kitchens, dining areas and gardens.

​

French doors installed within an existing opening will typically cost between £1,200 and £2,500 supplied and fitted. Standard white UPVC versions can sometimes cost less, while aluminium, timber and bespoke doors will be more expensive.

​

The price will depend on:

​

• The width and height of the opening

• UPVC, aluminium or timber frames

• Double or triple glazing

• Opening direction

• Threshold design

• Security hardware

• Side panels or fanlights

• Internal and external making good

​

Creating a completely new opening will add structural and building work to the cost.

​

​

Sliding Patio Door Installation Costs

 

Sliding patio doors provide broad views and do not require space for the doors to swing into the room or garden.

​

A standard replacement sliding patio door may cost approximately £1,800 to £5,000 supplied and fitted. UPVC systems are generally at the lower end, while aluminium frames and large lift-and-slide systems cost more.

​

Current cost guides place aluminium sliding doors at approximately £1,800 to £4,200, with around £3,000 being a representative installed figure for a standard project.

​

Large sliding panels may require specialist lifting equipment and additional installers. Oversized glazed units, slim-frame systems and automated doors will increase the overall cost.

​

​

Bifold Door Installation Costs

 

Bifold doors are formed from several connected panels that fold to one or both sides of the opening.

​

A standard installed bifold system will generally cost between £2,500 and £8,000, depending on the width, number of panels and frame material. Around £3,000 to £5,000 is a common guide for a modest residential installation, while large aluminium systems can cost significantly more.

​

The number of panels has a substantial effect on the cost because every panel requires its own frame, glazing, hinges, rollers, seals and locking components.

​

The structural opening must also be accurate and level. Poor support or movement above the doors can affect alignment and prevent the panels from opening smoothly.

​

​

Installing Doors in an Existing Opening

 

Replacing an old door with a new door of approximately the same size is normally the most economical installation.

​

The fitter will usually:

​

1. Remove the existing door and frame.

2. Inspect and prepare the opening.

3. Position and secure the new doorset.

4. Insulate and seal around the perimeter.

5. Fit trims, handles and hardware.

6. Adjust the hinges and locks.

7. Make good minor internal and external finishes.

​

Where the existing opening is square, structurally sound and suitable for the new door, the work may be completed within a day.

​

Rotten timber, damaged masonry, uneven floors and hidden structural issues can increase both the time and cost.

​

​

Creating or Enlarging a Door Opening

 

Creating a new door opening or replacing a small window with French, sliding or bifold doors is a larger building project.

​

In addition to the doors, the work may require:

​

• Temporary structural support

• A new steel beam or lintel

• Structural calculations

• Brickwork removal

• New jambs and thresholds

• Floor alterations

• Plastering and decoration

• External paving or steps

• Electrical or plumbing alterations

• Building-control approval

​

Structural alterations for bifold or patio doors can add approximately £500 to £1,500 or more before allowing for wider building work and finishes. Complex openings may cost considerably more.

​

The door supplier’s quotation may cover only the door system and installation. Building and structural work should therefore be identified and priced separately.

​

​

What Affects Door Installation Costs?

​

Door Material

UPVC is generally the least expensive option. Composite doors normally sit in the middle of the price range, while aluminium and bespoke timber doors are usually more expensive.

​

Door Size

Standard-sized doors cost less than bespoke or oversized products. Larger doors require more material, heavier glazing and stronger hardware.

​

Glazing

The cost increases when doors include:

​

• Large glazed panels

• Triple glazing

• Acoustic glass

• Laminated security glass

• Decorative glazing

• Integral blinds

• Leaded or patterned glass

​

Safety glass will normally be required in critical locations within and alongside glazed doors.

​

Side Panels and Fanlights

A front door with glazed panels on one or both sides will cost more than a single door. A top light above the door also adds another frame and glazed unit.

​

Security Hardware

Enhanced cylinders, multi-point locks, reinforced hinges, security handles and smart locking systems can increase the price.

​

Homeowners should establish exactly which locks and security standards are included rather than assuming every composite or aluminium door provides the same level of protection.

​

Colour and Finish

White UPVC is usually the least expensive finish. Woodgrain foils, premium composite colours, dual-colour frames and bespoke aluminium powder coating will cost more.

​

Access

Straightforward ground-floor access keeps installation costs down. Restricted entrances, narrow passages, scaffolding and heavy glazed units can require additional labour or specialist equipment.

​

Location

Labour and operating costs vary across the UK. Installations in London and parts of the South East may cost more than comparable work in other regions.
