A builder carries out and coordinates construction work — extensions, renovations and structural alterations — managing the trades beneath them. Structural work needs building control approval, and work affecting a shared wall needs a party wall award served in advance. The completion certificate is what a buyer’s solicitor asks for years later, so its absence becomes a problem long after the scaffolding is down.

Quick answer

What does a builder do, and how should you structure the payments?

A builder manages and carries out construction work — extensions, renovations, structural alterations — coordinating the trades beneath them. Domestic projects typically run £1,000–£10,000 and upward. Structural work needs building control approval and, where it affects a shared wall, a party wall award. Never pay a large deposit up front: stage payments against completed and inspected work are the norm, and the protection.

Builder vs main contractor vs project manager — who carries the risk

Factor	Builder	Main contractor	Project manager
Employs the other trades	✅ Usually	✅ Yes	❌ You do
Single point of responsibility	✅ Yes	✅ Yes	⚠️ Advisory
Suits a single-room job	✅ Yes	⚠️ Overkill	❌ Overkill
Suits a full house renovation	⚠️ Depends on size	✅ Recommended	✅ With trades
You manage the programme	❌ No	❌ No	⚠️ Jointly

Managing your own trades saves the builder’s margin and costs you the coordination risk — if the plasterer arrives before the first fix is signed off, that delay is yours. It is a real saving only if you can be on site and make decisions quickly.

TradeMatch eliminates these risks — every builder is vetted, insured, and payments are escrow-protected.

Best Time to Hire a Builder
