Before you hire

How to check a tradesperson before you commit

We match you with local trades and step back — the hiring decision is yours. These are the checks that separate a good tradesperson from an expensive mistake, and they take about ten minutes.

Get the quote in writing

An itemised written quote covering labour, materials, waste removal and VAT — not a figure over the phone. If two quotes differ a lot, it is usually because they cover different work, and only the written detail shows you where.

Check the insurance yourself

Ask for the public liability certificate and check the policy is current and in the same trading name as the quote. A logo on a van or a website is not evidence. If the work is notifiable, ask who is registering it.

Ask for recent local work

Two or three jobs of the same type from the last six months, close enough to go and look at. Someone who does good work will offer these before you ask. Be wary of anyone who only has photographs.

On payment: never pay the full amount up front. A deposit against materials is normal; after that, stage payments against completed work are the standard arrangement. Pressure to pay in cash, in full, or on the day is the single most common warning sign.

Why Choose Us

The Safest Way to
Find a UK Builder

Rogue traders and unreliable builders are a real risk. BestBuilders removes that risk with our rigorous 5-step vetting process — so every builder you hear from has been vetted before joining.

How we vet builders →

Check Their Insurance

Ask each builder for their minimum £2m public liability cover before work starts; we do not check it for you.

Vetted & Monitored

We vet every tradesperson before they can receive leads, and remove those with consistent complaints.

Check Their Qualifications

CIOB, FMB, Gas Safe, NICEIC, NFRC — ask to see the membership relevant to your job and check it on the body's register.

Common Questions

Frequently Asked Questions

How do I find a reliable builder in the UK?

Use BestBuilders to find vetted local builders — enter your postcode and project type to receive 3 free, no-obligation quotes from qualified builders in your area. Every builder on our platform is vetted before they can receive enquiries. Never pay a builder more than 10–20% upfront, always get quotes in writing, and check they're registered with a relevant trade body such as FMB or CIOB.

How much does a house extension cost in the UK?

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 than the national average. See our full extension cost guide for detailed breakdowns and a free cost calculator.

How quickly can I get quotes from builders?

Through BestBuilders you typically receive your first quotes within 24–48 hours of submitting your request. During peak seasons (spring/summer) it may take slightly longer for site visits and detailed quotes, but initial contact usually happens same day.

Do I need planning permission for a house extension?

Many extensions fall under Permitted Development rights and don't require planning permission. However you'll 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 full details, or ask any of the builders who quote for advice specific to your property.

Are the builders on BestBuilders insured?

Yes. Every builder on the BestBuilders platform is vetted before they can receive enquiries. We recommend you also ask any builder for proof of public liability insurance and relevant trade qualifications, and check them before you hire.

Is it free to get quotes through BestBuilders?

Completely free for homeowners. Getting up to 3 quotes through BestBuilders costs you nothing and there is no obligation to proceed. We charge builders a small fee when they win work through our platform, which is how BestBuilders stays free for homeowners.

Building costs are rising — what waiting a year costs

+13.1%

forecast rise in building costs over the next five years (BCIS, June 2026)

forecast rise in tender prices — what builders quote — by 2031 (BCIS)

Today’s prices: BestBuilders 2026 dataset — average “starting from” single-storey extension price across 500+ UK towns, by region. Orange = the extra you’d typically pay starting the same project 12 months later if costs follow the BCIS forecast (+3.8%/yr). Projections are indicative — actual prices vary by job and area. Sources: BCIS Construction Industry Forecast · our 2026 Cost Index.

The same maths applies to lofts, kitchens, roofs and driveways — materials and labour rarely get cheaper. Locking in quotes now fixes today’s prices.
