Every job certified and documented, every space made good — and a proper handover before we leave.
Areas we cover
Local enough to come back.

Before you book
Is the online price accurate?↓
It's an honest guide range for a typical installation — materials, labour and VAT included — not a teaser number. Your exact price is confirmed at the free survey and put in writing, and once it's in writing it doesn't change.
Do I have to pay anything now?↓
No. The calculator is free and anonymous, the survey is free, and the quote comes with no obligation. Requesting a provisional slot costs nothing — nothing is confirmed until we've spoken to you personally.
How fast can you fit?↓
Most standard boiler swaps can go in as soon as the next working day once you've accepted your fixed price. Conversions and multi-room air conditioning take a little longer — we'll always tell you upfront when we confirm your slot.
What happens after I request a slot?↓
A real person checks the diary and confirms your booking personally — no automated confirmations for a time we can't actually make. If your slot doesn't work, we'll offer the nearest one that does.
