A porch is a small enclosed structure built over a front or side door, adding a weatherproof entrance space for coats, shoes and deliveries, improving security and reducing draughts and heat loss from the house.
In Chippenham, as anywhere in Wiltshire, the price of a new porch is driven mainly by size, materials and access. Across the South West our guide sits at £3,600–£8,200 with VAT, but restricted parking, a narrow side passage or extra preparation can move the figure either way. That is why every price we give follows a visit to the house.

Homes in Wiltshire
Salisbury has medieval and Georgian streets, the north-west around Corsham and Bradford on Avon uses Bath stone, and chalk and flint appear on the downland. Swindon has railway-village terraces and very large post-war and modern estates, and many Wiltshire villages have thatched cottages, some with chalk cob walls.
Cob and Bath stone walls need breathable, lime-based repairs, and thatched cottages may need careful roof work. Swindon's railway terraces suit loft rooms and rear extensions, while its large estates often add garage conversions, driveways and landscaping.
None of this holds for every street in Chippenham, which is why we look at your actual house before pricing a new porch rather than assuming from its age alone.
Do you need permission in Chippenham?
Chippenham is in England, so the planning and building rules set out below are the ones that apply. We confirm the details with the council before we quote.
In England, a porch is usually permitted development if its ground floor area is no more than 3 m², no part is higher than 3 m, and it is at least 2 m from any boundary with a road.
Small porches at ground level are usually exempt from Building Regulations if the front door stays in place between porch and house, but safety glazing and any electrics must still comply.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
How does the job run?
Free site survey
First, someone visits your home in Chippenham to see the space, take measurements and note anything that could affect the work, such as access or the condition of what is there. There is no charge for this visit.
Price and scope agreed
We put everything into a written, fixed-price quote: the specification, what's excluded, staged payments and the expected time on site. Take whatever time you need to decide; there's no pressure to commit.
Plan and prepare
With the quote agreed, we book the work in and handle preparation: permissions where needed, building control notifications, material orders and access arrangements for your Chippenham property.
Finish and handover
During the work we protect the areas around it and tidy up at the end of each day. Once complete, we check the finish, remove our materials and hand over paperwork such as building control sign-off where it applies.

Questions about a new porch in Chippenham
Which postcodes in Chippenham do you cover?
We cover SN15, along with the rest of Wiltshire. If your postcode is not listed, get in touch anyway: our coverage is UK-wide, and we can usually arrange a survey wherever you live. Enter your postcode in the guide-price tool or contact form and we will confirm.
Will a porch make my house warmer?
A porch acts as a buffer between the front door and the outside, so cold air does not rush straight in every time the door opens. This reduces draughts in the hallway or living room and can help cut heat loss. It also gives a dry place to take off wet coats and shoes. Well-insulated walls, double glazing and a good door make the biggest difference.
What if there is a gas meter or drain where the porch will go?
A gas or electric meter box or a drain in the porch area does not usually stop a porch being built, but it affects the design and cost. Meters may need moving by the supplier, which takes time to arrange. Manholes can sometimes be enclosed with a sealed cover, depending on the drainage. We check these details at the survey and include them in the quote.
Do I need planning permission for a porch?
Whether a porch needs planning permission depends on its size and height, how close it is to a road, your home's location, whether it is listed or in a conservation area, and which UK nation you live in. In England, a porch is usually permitted development if its ground floor area is no more than 3m², no part is over 3m high and it is at least 2m from a boundary with a road. We check before quoting.
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 porch, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
