How to Choose a Builder in Islington

Islington sits within the London Borough of Islington's planning jurisdiction, and its housing spans everything from Victorian terraces to newer apartments - which means the right builder for one project here isn't necessarily right for another, even a few streets away.

Look for local experience, specifically

What separates a builder who genuinely knows Islington from one who just says they cover London is detail: familiarity with the Canonbury, Barnsbury and Highbury Fields conservation areas - 42 in total, covering roughly half the borough, a sense of typical foundation depths on the area's older terraces, and knowing how the London Borough of Islington usually handles permit applications for skips and scaffolding. Ask them plainly whether they've worked near Upper Street and Camden Passage or somewhere with a similar street layout.

Check the basics before anything else

• Public liability insurance - ask to see the certificate, not just be told it exists.
• Recent, verifiable reviews - ideally with photos of similar work, and from customers you could plausibly contact.
• A written quote that breaks down labour, materials and any provisional sums, not a single lump figure.
• Who's actually doing the work - some builders subcontract everything; that's not necessarily a problem, but you should know upfront.

Get more than one quote, on the same brief

Give every builder you approach the same written description of the job, rather than a slightly different explanation each time - it's the only way to compare quotes fairly. A wide spread between quotes for the same brief is usually a sign either the cheapest builder has missed something, or the most expensive one is pricing in more risk than the others - worth asking both why.
