Newport's housing stock keeps builders busy in very particular ways. Tight Victorian and Edwardian terraces in Pillgwenlly, Maindee and Stow Hill mean awkward access, party wall conversations and lots of structural steel for rear extensions. Further out, 1930s semis in Malpas and Bettws are prime loft conversion territory, while the post-war estates in Ringland and Duffryn tend to need renovation, reroofing and kitchen reworks. Add the Gwent Levels' clay-heavy ground and a high water table near the Usk, and foundations aren't something to skim over. Depth and drainage matter here.

The businesses on this page are drawn from third-party business listings and ranked by public review rating and review count, with a small lift for those showing a working website and phone number. We read each firm's homepage to confirm builders work is what they primarily offer, which keeps unrelated businesses off the page, and permanently closed listings are removed automatically. Where you see a Trust Verified badge, that business has additionally passed our full verification covering trade qualifications and accreditations, public liability insurance, trading history, customer review history, and registered company information. Our How We Verify page lists everything in full. For anyone without that badge, we haven't independently verified them, so those checks are yours to do before you book.

Start by asking every builder for written, itemised quotes, and get two or three so you can see where prices and scopes differ. Ask for proof of public liability insurance and check the cover amount suits your job. Find out whether they hold relevant trade accreditation, and ask who handles Building Regulations sign-off with Newport City Council's building control team. If your project touches a shared wall or boundary, you'll probably need a Party Wall notice, so ask who's serving it. Agree a payment schedule tied to stages of work, never a large upfront deposit, and get the start date and expected duration in writing. Ask to see recent similar jobs, or speak to a past customer nearby.

Frequently Asked Questions

How much does a builders cost in Newport?
It depends heavily on the job. A single-storey rear extension on a terrace in Maindee or Stow Hill typically runs from around £1,800 to £2,500 per square metre, so a 20 square metre extension might land between £36,000 and £50,000. A dormer loft conversion on a 1930s semi in Malpas or Bettws usually costs £40,000 to £65,000. Smaller work is often priced by the day, with a good builder charging roughly £180 to £250 per day. Access, ground conditions, spec and whether you need structural steel all shift the figure. Get two or three itemised quotes so you can compare like for like.
Do I need planning permission for an extension or loft conversion in Newport?
Often you don't, as many rear extensions and loft conversions fall under permitted development. But it isn't automatic. Conservation areas such as parts of Stow Hill and Caerleon have tighter rules, and flats and some converted properties have no permitted development rights at all. Check with Newport City Council's planning team before committing, and consider a lawful development certificate for peace of mind. Building Regulations approval is a separate requirement and nearly always applies, regardless of planning.
Will I need a Party Wall agreement?
If you're building on or near a boundary shared with a neighbour, digging foundations within three metres of their building, or cutting into a shared wall, the Party Wall etc. Act 1996 applies. That's common on Newport's terraced streets. You serve notice on your neighbours, and if they dissent you'll need surveyors, which can cost £700 to £1,500 or more. Ask your builder whether they expect it and who's responsible for serving notices. Don't start work until it's settled.
How long does a typical building project take?
A kitchen or bathroom renovation usually takes two to six weeks. A single-storey extension runs around three to five months from groundworks to finish, and a loft conversion often takes six to ten weeks on site. Add time beforehand for drawings, planning, Building Regulations and any party wall process, which can easily be two or three months. Weather affects groundworks, and Newport's wet winters can slow foundations. Ask for a realistic programme in writing, and expect small slippages.
How should I pay a builder?
Pay in stages tied to completed work, not on a calendar. A small deposit for materials is reasonable, but be wary of anyone asking for large sums upfront or cash only. A typical schedule might be a modest deposit, then payments on completing groundworks, reaching wall plate or roof, first fix, and a final balance held back until snagging is done. Get it written into the contract and keep invoices and receipts for every payment.
How do I check a builder is reliable before hiring?
Start with paperwork. Ask for proof of public liability insurance and check the cover level and expiry. Ask whether they hold relevant trade accreditation and confirm it with the issuing body directly. Look up the company on Companies House if they trade as a limited company, and read online reviews for patterns, not just the star rating. Ask for addresses of recent jobs and, ideally, speak to a customer. Then compare at least two or three written quotes. If a builder dodges any of this, move on.
