Everything You Need to Know
Local Builders for Every Type of Project
Finding a reliable local builder is one of the most important decisions you will make for your home. BestBuilders connects you with vetted, reviewed builders who understand local planning requirements, building regulations and the construction challenges specific to your area.
Whether you are planning a rear extension on a Victorian terrace, a dormer loft conversion on a 1930s semi, or a full kitchen renovation, our network covers every type of residential and commercial project across England, Scotland and Wales.
Why choose a local builder?
Local builders understand your area’s planning policies and conservation area restrictions, have established relationships with local building control officers, and often source materials from nearby suppliers — which can reduce costs and lead times.

Common Questions
Builder FAQs
Select your town or city from the directory above, or enter your postcode in the quote form. We match you with up to 3 vetted local builders who cover your area. Every builder in our network has verified insurance, trade qualifications and a minimum of 5 real customer reviews.
A single-storey extension typically costs £25,000–£55,000 in the UK (£1,500–£2,200/m²). A double-storey extension ranges from £45,000–£100,000. London and South East costs are typically 20–30% higher. See our full extension cost guide for detailed breakdowns and a free cost calculator.
You will typically receive your first quotes within 24–48 hours of submitting your request. During peak seasons (spring and summer) it may take slightly longer for detailed site-visit quotes, but initial contact usually happens the same day.
Many extensions fall under Permitted Development rights and do not require planning permission. You will need to apply to your local council if your home is listed, in a conservation area, or if the extension exceeds Permitted Development size limits. Visit our planning permission guide for details.
Completely free for homeowners. There is no obligation to proceed with any quote. We charge builders a small fee only when they win work through our platform, which is how we keep the service free for you.
A reasonable deposit is 10–25% of the contract value, capped at materials cost for the first phase of work. Never pay 50% or more upfront — this is the #1 red flag for rogue traders. For projects over £5,000, structure payments in stages tied to milestones (e.g. 20% deposit, 30% at first-fix, 30% at second-fix, 20% on completion + retention). For sums over £30,000, use an escrow service or stage release through a solicitor.
For projects under £10,000, a simple written quotation (scope, price, materials, timeline, payment terms, snagging period) is sufficient. For projects over £10,000, use a JCT Homeowner Contract (industry standard, £30–£50 from the JCT website) or the FMB Build Assure contract. Both protect both parties on variations, delays, defects and insurance. Never accept a verbal agreement for any work over £1,000 — if there's a dispute, you have no evidence.
Three policies, all verifiable: Public Liability Insurance (minimum £2m, ideally £5m+ for larger jobs) — covers damage to your property or injury to third parties; Employers' Liability (minimum £5m, legally required) — covers their staff/subbies; Contractor's All Risks (CAR) — covers materials and work in progress against fire, theft, weather damage. Ask for copies of certificates before signing — not a logo on the website. Every builder on Best Builders has insurance verified at listing.
FMB (Federation of Master Builders) — trade body with vetted members; offers FMB-backed insurance warranties. TrustMark — government-endorsed quality scheme; useful for tradespeople doing energy/green work. NHBC — new-build warranty; relevant if your builder is constructing a new structure or self-build. CIOB — professional standards for site managers and larger contractors. Gas Safe / NICEIC / OZEV — mandatory for gas/electrical/EV work. The combination matters more than any single badge.
Yes — treat cash-only as a major red flag. Legitimate builders accept bank transfer (preferred), card payment, or cheque, and provide VAT receipts. Cash-only typically signals: not VAT-registered (limits scope to small jobs); avoiding tax (your problem if HMRC investigates); no audit trail if the work fails. There's no consumer benefit to paying cash — you lose Section 75 protection (cards), bank transfer evidence, and your right to chase. Stick to traceable payments.
A genuine risk for any UK building project. Protections, in order of strength: (1) FMB Build Assure warranty — covers project completion with another contractor if your FMB-member builder ceases trading. (2) Card payment / Section 75 — if you paid by credit card for any portion over £100, the card issuer is jointly liable. (3) Insurance-backed guarantee (IBG) — usually offered by NFRC roofers, FMB members, MCS installers. (4) Stage payments — never pay more than 25% ahead of actual work delivered. Without these protections, you're largely uninsured.
Yes, under the Consumer Rights Act 2015, you can withhold payment proportionate to defects, but you must follow the right process: (1) Document defects in writing immediately on completion (photos, dated list); (2) Give the builder reasonable opportunity to fix; (3) If they refuse, withhold an amount proportionate to remedial cost. Withholding more than the cost to fix or refusing to engage at all weakens your position. For amounts over £5,000, get independent surveyor input before withholding.
The Consumer Rights Act 2015 requires all building work to be: (1) Performed with reasonable care and skill; (2) For a reasonable price if not pre-agreed; (3) Within a reasonable timeframe if not pre-agreed; (4) Using materials of satisfactory quality, fit for purpose, and as described. If any fail, you can: ask for the work to be re-done at no extra cost (first remedy); request a price reduction; or in serious cases, terminate the contract. Your rights cannot be excluded by contract terms.
