Honest Repair-or-Replace Advice
If a repair isn't worth it, we'll say so - and explain your options without pressure.
Common Boiler Faults We Fix
Some problems come up again and again in Sussex homes: boilers losing pressure (often a small leak or a failing expansion vessel), no hot water (commonly a diverter valve or sensor), banging or kettling noises (usually limescale or sludge), frozen condensate pipes in cold snaps, and error codes that lock the boiler out.
If your boiler is showing an error code, make a note of it before you call - it often tells us exactly where to look and means we can arrive with the right parts.
Repair or Replace?
As a rule of thumb: if your boiler is under 10 years old and the repair is modest, repair it. If it's over 10 years old and the repair runs into hundreds of pounds - especially for a major component like a heat exchanger - replacement usually makes better sense, because a new A-rated boiler will also cut your gas bills significantly.
Our guide on the signs it's time to replace your boiler covers this in more detail.

Boiler Repairs FAQs
How quickly can you get to me?
We prioritise homes with no heating or hot water and can usually attend within 24 to 48 hours of your call - often sooner for vulnerable households. Call 07711 120 788 and we'll give you an honest arrival time.
Do you charge a call-out fee?
We charge a fair diagnostic fee that covers the engineer's visit and a proper fault diagnosis. You'll know the cost before we book the visit, and you'll get a fixed quote for the repair before any work starts.
Can you repair a boiler that's out of warranty?
Yes - out-of-warranty boilers make up most of our repair work. We use genuine or manufacturer-approved parts and our workmanship is guaranteed.
My boiler keeps losing pressure - is that serious?
It's one of the most common faults we see. The cause is usually a small leak in the system or a failing expansion vessel rather than anything dangerous, but it shouldn't be ignored. Our guide on boiler pressure loss explains the causes, and a visit usually pins it down quickly.
When is it not worth repairing a boiler?
When the boiler is over 10 years old and the repair involves a major component, the maths rarely works. We'll always give you both numbers - repair cost versus replacement - so you can decide with the full picture.
