A replacement front or back door is a new door and frame, usually composite, uPVC or aluminium, made to fit your existing opening and fitted with multi-point locks and weather seals to improve security, warmth and kerb appeal.
Whatever prompted you to look into a new front or back door, whether wear and tear, a growing family or plans to move, we can survey your Westminster home and give you a price in writing. Homes in London typically come in at £1,300–£4,600, VAT included, for this kind of work. We also cover Pimlico, Soho and Chelsea, and the same steps apply wherever you are in London.

Building in Westminster
London's housing is dominated by Victorian and Edwardian terraces, often in yellow London stock brick, with Georgian terraces in central districts and mansion blocks across many inner areas. Outer boroughs have large belts of interwar semis, and there are extensive post-war council estates. Many houses have been split into flats, and conservation areas are widespread.
Terraces suit side-return extensions and rear dormer loft conversions; interwar semis commonly take hip-to-gable lofts. Shared party walls, restricted parking and conservation rules often shape the plans and the programme.
For a new front or back door in Westminster, this means checking things like wall construction, roof structure and existing services before we put a figure on paper.
Planning and building rules in Westminster
Westminster is in England, so the planning and building rules set out below are the ones that apply. We confirm the details with the council before we quote.
Replacing windows and doors on a house is usually permitted development in England when the new ones look broadly similar to the old. Flats, listed buildings and homes covered by an Article 4 direction can need consent, and conservation areas may limit materials or styles.
Replacement windows and external doors must meet Building Regulations for energy efficiency, ventilation and, on upper floors, escape. The work is either self-certified by an installer registered with a competent person scheme or signed off by building control.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
What happens after you get in touch?
We look at the job
We arrange a free site survey on a date convenient to you. We measure up, look at the existing structure and access, and discuss your plans for a new front or back door so the price reflects your home.
Price and scope agreed
The quote arrives in writing, not over the phone. It covers the full scope, the finishes you've chosen, any exclusions and the payment schedule, with a fixed price tied to that specification.
Plan and prepare
Preparation matters as much as the build. We agree access, parking and working hours with you, order materials in good time, and confirm any permissions so the job isn't held up once it starts.
The work itself
During the work we protect the areas around it and tidy up at the end of each day. Once complete, we check the finish, remove our materials and hand over paperwork such as building control sign-off where it applies.

Front and back doors in Westminster: questions
How much does a new front door cost?
A new front door costs £1,300–£4,600 supplied and fitted, depending on the material, the amount of glass and whether you want side panels. A uPVC back door sits at the lower end, a composite front door in the middle, and aluminium doors or doors with side panels at the top. Locks, letterplates and dual colours also affect the figure. We confirm a fixed price in writing after measuring your opening.
How long will a new front or back door take?
On a typical home, allow Usually half a day to one day per door. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.
How secure are modern doors?
Modern external doors are far more secure than older designs because they lock at several points along the frame, not just at the handle. We fit anti-snap cylinders, which resist a common method of forced entry, in reinforced frames. Laminated or toughened glass panels add further protection. For extra peace of mind you can add a door chain, a viewer or a smart lock, which we can include in your quote.
Do I need permission to change my front door?
Planning permission is not usually needed to replace a front door, but it depends on the style and size of the change, your home's location, whether it is listed or in a conservation area, and which UK nation you are in. Listed homes generally need consent for any change, and some conservation areas control colours and styles. Flat entrance doors in shared buildings must also meet fire rules. We check before quoting.
Do you cover Pimlico, Soho and Chelsea?
Yes. As well as Westminster, we cover Pimlico, Soho and Chelsea and the rest of London. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
