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.

In Kempston, a porch typically costs £7,000–£17,000 from a 3 m² porch to a small front extension, including VAT at 20% (standard rate).

Do you need planning permission for a porch in Kempston?
The approval route for Kempston is set by planning law 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.
We check this for your address before design work starts, so there are no surprises later.

Do I need planning permission for a porch?
In England a porch is permitted development if its ground floor area is no more than 3 square metres, no part is higher than 3 metres and it is at least 2 metres from any boundary next to a road. Larger porches need an application.
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.

A downstairs toilet usually needs a larger front extension, a drainage connection and building regulations approval.
