New boiler cost in Leeds (2026 price guide)
If you are pricing up a new boiler in Leeds, the real answer is that it depends on your home — but the range is narrower than the “from £X” adverts suggest. Here is what Leeds homeowners actually pay in 2026 and what moves the number.
Typical fitted prices in Leeds
- Combi swap (like-for-like): from £1,695 fully fitted. The most common Leeds job, usually done in a day.
- System or regular boiler replacement: a little more, depending on the cylinder and controls.
- Converting system to combi: more again, because we drain the old cylinder, re-route the hot water feed and reinstate the airing cupboard, typically a two-day job.
Local aggregator listings quote Leeds installs anywhere from around £1,600 up to £3,000+, which is why a fixed price after a real survey beats a starts-from estimate every time.
New boiler prices in Leeds by brand
The brand you choose sets the band:
- Ideal Logic from £1,695 supplied and fitted, the budget pick that still carries a proper warranty.
- Worcester Bosch Greenstar from £1,895, the range we fit most across Leeds.
- Vaillant ecoTEC from £2,095, with the longest warranty cover of the three.
We are accredited installers for Worcester Bosch and Vaillant, so a registered install carries up to a 10-year warranty, and every quote includes the flush, filter, thermostat and warranty registration with nothing added on the day.
Boiler replacement cost in Leeds
A like-for-like boiler replacement is the cheapest way to do it: the old combi comes out in the morning and the new one is running by evening, from £1,695 all in. Swapping a system boiler and cylinder for a combi costs more and typically takes two days, but frees up the airing cupboard for good. Either way the price is fixed in writing after a 20-minute survey of the actual job, whether that is a back-to-back terrace in Headingley or Hyde Park with tight pipe runs, or a semi out in Horsforth, Pudsey or Garforth.
What pushes the price up or down
- Boiler type and output for the size of your home.
- Moving the boiler or changing the flue position.
- Older pipework and gas runs common in Headingley, Burley and other Victorian terraces, which sometimes need upgrading.
- Extras like a system filter, smart controls or a chemical flush.
Finance
Not everyone wants to pay in one go. Finance is available from around £23 a month subject to status, with 0% APR on selected models and a soft credit check that does not affect your score. You can spread the cost from £23 a month.
