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.
Homeowners in Barnet usually consider a new front or back door for one of a few reasons: something has worn out, the house no longer suits the way they live, or they are getting it ready to sell. We visit, agree a specification and put a fixed price in writing. Most jobs like this take Usually half a day to one day per door, and we work across London, including East Barnet, Hadley Wood and Potters Bar.

Building in Barnet
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.
London Clay shrinks and swells with the seasons, and street trees close to houses can contribute to movement, which affects foundation design.
That mix of housing shapes how we approach a new front or back door in Barnet: the age and construction of your home affect the materials, the method and, in the end, the price.
Planning and building rules in Barnet
Planning law differs across the UK. For a home in Barnet, it is the England rules below that count, and we check them with the council ahead of any 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 you can expect from us
Front and back doors in Barnet: 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 my home be open while the door is fitted?
Fitting a new door usually takes half a day to a full day, and your home is only open for the short time between taking out the old frame and fixing the new one. We keep the opening covered if there is any delay, and we never leave a doorway insecure overnight. Once the frame is fixed, we hang the door, adjust the locks, seal around the frame and finish the trims.
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 much will a new front or back door cost in Barnet?
As a guide, expect to pay £1,300–£4,600 including VAT for a new front or back door in Barnet. That range is adjusted for London, which runs about 30% above the national guide. Where your project lands depends on size, materials, access and the condition of what is already there. We confirm a fixed price in writing after a free survey of your home.
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.
