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 Thetford?
In Thetford, a porch typically costs £7,000–£17,000 from a 3 m² porch to a small front extension, including VAT at 20% (standard rate). We start from a UK-wide guide and adjust it for the East of England, where labour and materials are typically about 6% above average. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| From a 3 m² porch to a small front extension | £7,000–£17,000 |
| Higher specification | £17,000–£21,000 |
Your quote will depend mainly on:
- Whether building regulations apply
- Moving meters, drains or the doorbell and lighting
- Brick matching
- Size and roof style
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 Thetford?
Before anything is built in Thetford, 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.

From survey to sign-off, the job normally involves:

- Front door and windows
How long does it take?
Build time is typically 2 to 4 weeks on site. Design and approvals come first and typically take 6 to 12 weeks, depending on the approval route.

Can I have a toilet in my porch?
A downstairs toilet usually needs a larger front extension, a drainage connection and building regulations approval.
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.
