Boiler Repair in South London
We diagnose the fault first, then give you a fixed price. No repair started without your approval.
“Doing things the right way, not the easy way.”
If your boiler has stopped working, is making unusual noises, or isn't heating your home properly, we can diagnose the fault and fix it.
We don't guess. We diagnose first, give you a fixed price for the repair, and only start work once you've approved the cost. No surprises.
How Boiler Repair Works
We use a two-visit approach so you always know what you're paying for before any work starts.
Visit 1 — Diagnostic (£75+VAT)
We attend your property and do a full diagnostic of the boiler. We identify the fault, check related components, and give you a clear explanation of what's wrong and what it'll cost to fix.
The diagnostic fee is £75 + VAT, or £150 + VAT where the fault needs a longer investigation (we tell you before we start which applies). It is charged as its own job, payable once the investigation has been completed, and is not deducted from any later repair.
Visit 2 — Repair (quoted price)
Once you approve the quote, we order the parts and come back to do the repair. The price you were quoted is the price you pay — no hourly overruns, no extras.
If the boiler isn't worth repairing, we'll tell you honestly and can discuss replacement options instead.
