Your questions, answered
Do I get a quote before the boiler repair starts?
Yes — once we've diagnosed the fault you get a written, fixed-price quote before any repair starts. No surprise bills.
Do you repair all boiler brands in North London?
Yes — Worcester, Vaillant, Ideal, Baxi, Viessmann, Glow-worm, Potterton, Vokera, Main and more. Our vans are stocked with the most common spare parts for same-day fixes.
Is it worth repairing my old boiler?
If your boiler is under 8 years old and the repair is under 30% of replacement cost, it's almost always worth fixing. We'll give you a straight answer based on your specific unit.
Can you attend a boiler breakdown the same day?
Yes — across North London we offer same-day boiler repair appointments for most faults, and 2-hour response for genuine no-heating-or-hot-water emergencies.
