If your combi is showing any of these warning signs, replacing it now can save you money on rising repair bills and energy costs — before it lets you down mid-winter.
Most combi boilers are built for a 10–15 year life. Beyond that, efficiency drops and breakdowns become far more likely.
Calling an engineer every winter? Repeated repair bills quickly add up to more than a new, fully warrantied boiler.
A new A-rated combi runs at over 90% efficiency, compared to 60–70% for older units — noticeably cheaper to run every month.
Lukewarm showers, radiators slow to warm up, or hot water that runs cold are classic signs of a struggling combi.
Gurgling, banging or kettling sounds often point to limescale or a failing heat exchanger — rarely worth repairing on an old boiler.
Water pooling around the boiler, or a pressure gauge you top up every week, signals internal wear that’s only going to get worse.
From your free survey to final commissioning, we make swapping your combi boiler simple, fixed-price and stress-free — with warranties that give you real peace of mind.
Premium combi boilers from the brands you trust, fitted to manufacturer spec so you unlock the longest warranties available.
Extended manufacturer warranties on Worcester Bosch, Vaillant, Ideal & Baxi combis when we install them — fully registered on your behalf.
Every combi replacement is backed by a minimum 12-month workmanship guarantee on top of your manufacturer warranty.
A clear, fixed price up front and most swaps completed in a single day by Gas Safe registered engineers.
Free, no-obligation survey with a written fixed price — no hidden extras and no pressure to commit.
Like-for-like combi replacements are typically completed in a single day, with minimal disruption to your home.
We remove and responsibly dispose of your old combi, flush the system and fully commission your new one.
