When your combi boiler, a type of boiler that heats water on demand and provides central heating without a tank. Also known as combination boiler, it’s the most common choice in UK homes because it saves space and cuts energy waste. stops working, the first question isn’t just "Who do I call?"—it’s "How much is this going to cost?" A new combi boiler isn’t a small expense, but neither is ignoring it. The average price in 2025 ranges from £1,800 to £3,500, depending on brand, output, and whether you’re replacing like-for-like or upgrading. That’s not just the unit cost—it includes fitting, flue work, and safety checks by a Gas Safe engineer.
What drives the price up? Brand matters—Baxi, Vaillant, and Worcester Bosch cost more upfront but often last longer and have better parts availability. Output size is another factor: if your home has three or more bedrooms, you’ll need a 30-35kW model, not a 24kW one meant for a small flat. Installation complexity adds cost too. If your old boiler was tucked behind a cupboard and the new one needs a new flue through an external wall, expect to pay more. And don’t forget: if your pipes are old or your system needs a powerflush, that’s extra. Some people try to cut corners with non-Gas Safe fitters to save £500, but a bad install can lead to leaks, carbon monoxide risks, or voided warranties. It’s not worth the gamble.
But here’s the thing—sometimes replacing your boiler isn’t the smartest move. If your unit is under 10 years old and just needs a new pump, control board, or pressure sensor, a £200–£400 repair might give you another 5 years.
