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.
We offer a new porch throughout Wiltshire, from Swindon, Salisbury, Trowbridge and Chippenham to the smaller places in between. Each project starts with a free survey at your home and ends with a written figure, fixed for the work you choose. Because Wiltshire is in England, we work to the planning system and building standards used there, and guide prices for the South West run at £3,600–£8,200 including VAT.

How much does a new porch cost in Wiltshire?
What will a new porch cost in Wiltshire? Our guide range is £3,600–£8,200 including VAT. That figure is adjusted for the South West, about 2% above the national guide, and is intended for planning a budget. A firm written price for your chosen specification follows a free survey at your home.
| Type of job | What it usually involves | Guide in Wiltshire |
|---|---|---|
| Canopy or open porch | A tiled or lead canopy, or an open timber porch, over an existing door. | £1,000–£3,100 |
| uPVC or aluminium porch | A glazed enclosed porch on a brick dwarf wall with a new door. | £3,100–£5,600 |
| Brick-built porch | A fully brick-built porch matching the house, with tiled roof, windows and lighting. | £5,600–£10,000 |
The main things that change the figure:
- Construction: uPVC, aluminium, brick or timber frame
- Roof type and how it meets the house
- Door and window specification
- Drains, meters or paths that need moving
What’s included?
- Foundations and a concrete base with damp-proof membrane
- Brick dwarf walls or full brick walls to match the house
- Roof tiled or covered to suit the house, with flashing
- Windows and an external door in your chosen style
- Guttering and a downpipe connected to drainage
- Plastering, sills, skirting and flooring ready to use
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.
Salisbury Plain and the downs are exposed to wind and frost, while river valleys around Salisbury and the Avon can flood.
Planning and building rules in Wiltshire
Planning law differs across the UK. For a home in Wiltshire, it is the England rules below that count, and we check them with the council ahead of any 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.
The four stages
We look at the job
A free survey comes first. It gives us what we need to price a new porch properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Quote in writing
Next you receive a written quote with a fixed price for the agreed specification. It lists what is included, what is not, and how payments are staged, so you can compare it properly.
Plan and prepare
Once you accept, we agree start dates, order materials and deal with any planning, building control or neighbour notices the job needs. You'll know who is coming and when before work begins.
Finish and handover
Work goes ahead as scheduled and you deal with one contact throughout. When the last trade leaves, we clear and clean the site, talk you through what has been done and pass on any certificates and care instructions.
What you can expect from us
Questions about a new porch in Wiltshire
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.
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
Does a porch need building regulations approval?
Small porches are often exempt from building regulations, provided the existing front door stays between the porch and the house and the floor area is modest. Glazing must still be safety glass and any electrics must be certified. If you remove the front door so the porch becomes part of the house, it is treated like an extension. Rules vary between UK nations, so we confirm what applies.
Who do I deal with during the job?
One point of contact manages your project from survey to handover. They schedule the trades working under our contract, keep you updated on progress, and are the person to call with any question. You don't need to coordinate builders, electricians or decorators separately, because that is part of what we do.
What style of porch suits my house?
The right porch style usually echoes your house. Brick-built porches with a tiled roof suit traditional brick homes, while uPVC or aluminium porches suit newer houses and give more light. Matching the roof pitch, brick colour and window style to the house helps the porch look as if it has always been there. We bring photos and options to the survey.
