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 Blackburn?
In Blackburn, a porch typically costs £6,000–£15,000 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 North West, where labour and materials are typically about 6% below average. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| From a 3 m² porch to a small front extension | £6,000–£15,000 |
| Higher specification | £15,000–£19,000 |
What moves the price most:
- Whether building regulations apply
- Brick matching
- Moving meters, drains or the doorbell and lighting
- Front door specification
A guide range is only a starting point: the guide price tool gives an instant figure for your size, and a free survey turns it into a fixed quote.
Do you need planning permission for a porch in Blackburn?
Approvals for a porch in Blackburn follow the rules for 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.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
