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.
Cardiff sits within our coverage for a new porch, as do neighbouring Penarth, Caerphilly and Barry. Before giving a price we want to see the property: the condition of what's there now, the access, and anything that might need extra work. The guide range for Wales is £3,200–£7,400 including VAT, and your written quote will spell out exactly what that covers.

Homes in South Glamorgan
Cardiff has large areas of bay-fronted Victorian and Edwardian terraces in districts such as Roath, Canton and Cathays, plus interwar suburbs, post-war estates and modern flats around Cardiff Bay. Penarth has Victorian villas, Barry mixes terraces with newer estates, and Vale of Glamorgan villages are often built of local limestone.
Mild but wet, with coastal exposure along the Severn estuary and Bristol Channel affecting render, roofline and windows.
If your house in Cardiff fits one of these patterns, it helps us anticipate what a new porch will involve, though we always confirm the details on site.
Planning and building rules in Cardiff
For anyone in Cardiff, the relevant framework is Wales's. The summary below is general, so we always contact the council about your address before putting a price in writing.
In Wales, a small porch is usually permitted development within similar floor-area, height and road-distance limits.
Small ground-floor porches are often exempt from Building Regulations, but glazing and electrics must 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
We begin by looking at the job in person. During the free survey we discuss options, materials and budget for a new porch, and photograph or measure anything the quote needs to reflect.
Written quote
After the survey we send a quote for a new porch that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
Dates and permissions
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 Cardiff property.
The work itself
The work is carried out to the agreed specification, with floors and furniture protected and the site kept tidy. At the end we clean up, walk through the finished job with you and hand over any certificates.

Frequently asked questions
Do you cover Penarth, Caerphilly and Barry?
Yes. As well as Cardiff, we cover Penarth, Caerphilly and Barry and the rest of South Glamorgan. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
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 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.
How long will a new porch take?
On a typical home, allow 1–2 weeks on site. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.
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.
Nearby towns
