What is a porch?
A porch is a small extension built around the front door, giving a lobby for coats and shoes and stopping draughts reaching the hall. Most are brick with a pitched tiled roof to match the house, though glazed and timber porches are also common.
How much does a porch cost in Bromley?
In Bromley, a porch typically costs £8,500–£21,000 from a 3 m² porch to a small front extension, including VAT at 20% (standard rate). The guide for Bromley reflects typical costs in London, roughly 30% above the UK-wide figure. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| From a 3 m² porch to a small front extension | £8,500–£21,000 |
| Higher specification | £21,000–£26,000 |
Your quote will depend mainly on:
- Moving meters, drains or the doorbell and lighting
- Whether building regulations apply
- Front door specification
- Brick matching
Your exact price depends on the survey and drawings. The guide price tool gives a quick range in the meantime.
Do you need planning permission for a porch in Bromley?
Before anything is built in Bromley, we confirm which approvals apply in England. In England a porch is permitted development if its ground floor area is no more than 3 square metres, no part is over 3 metres high and it is at least 2 metres from a boundary next to a road.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.

Questions about porches in Bromley
Can you move the gas or electric meter?
Meters belong to the supplier or network operator. We coordinate their move as part of the job, which can add time.
Do you build porches in Bromley?
Yes. We build porches across Bromley, including postcodes BR1. Every project starts with a free home visit.
How long does it take?
Usually 2 to 4 weeks on site.
Does a porch need building regulations?
In England and Wales a ground-level porch under 30 square metres is usually exempt if the front door stays in place and the glazing meets safety standards. In Scotland the exemption is much smaller (around 8 square metres, with no new opening into the house). If the front door is removed, approval is needed. We check this for your design.
