We publish a guide of £1,300–£4,600 including VAT for London up front, explain that work normally takes Usually half a day to one day per door, and confirm both in writing after a free survey of your property.

To help you plan, we show what a new front or back door typically costs in Blackheath instead of holding figures back for a sales call. The range is £1,300–£4,600 with VAT, using rates in London that are about 30% above the national guide. A free survey then fixes your actual price.

Building in Blackheath
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.
If your house in Blackheath fits one of these patterns, it helps us anticipate what a new front or back door will involve, though we always confirm the details on site.
Permissions for a new front or back door in Blackheath
Each UK nation sets its own consent rules, and Blackheath is in England. What follows is a plain summary; we check the specifics for your property with the council before pricing anything.
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.
The four stages
A visit to your home
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.
Quote in writing
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
Before anyone starts, we confirm the programme in writing, check whether consents are required and arrange deliveries. If a skip or scaffolding on the road needs a permit, we apply for it.
Finish and handover
The work is carried out to the agreed specification, with floors and furniture protected and the site kept tidy. At the end we clean up, walk through the finished job with you and hand over any certificates.

Frequently asked 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.
What is the difference between a composite and a uPVC door?
A composite door has a tough outer skin over a solid insulated core, so it feels heavier and more solid than uPVC and holds its colour well. A uPVC door is built from reinforced plastic panels and costs less. Both can have multi-point locking and good weather seals. Many people choose composite for the front door and uPVC for back or side doors, where looks matter less.
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.
What happens at the survey?
We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from a new front or back door, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
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.
