What Affects the Cost of a New Boiler?

Several factors determine the final price of your new boiler installation:

• Boiler type — combi boilers are generally the most affordable to install. System and regular boilers cost more due to the additional components required.
• Boiler brand and model — budget brands (Alpha, Baxi 400) start from £1,699. Premium brands (Worcester Bosch 8000, Viessmann Vitodens) cost more but offer superior efficiency and longer warranties.
• Property size — larger homes need a higher-output boiler, which costs slightly more. Our engineers will recommend the right size so you don't overpay for capacity you don't need.
• Boiler location — like-for-like replacement in the same location is quickest and cheapest. Relocating the boiler, extending flue runs or upgrading pipework adds cost.
• Conversion work — if you're switching from a conventional system (with a hot water cylinder and loft tanks) to a combi, there's additional labour for removing redundant components.
• Flue and gas supply — if your gas supply or existing flue needs upgrading, this will be reflected in your quote.

Hidden Costs to Watch Out For

Some boiler companies advertise low headline prices but add on extra charges later. Watch out for these:

• Magnetic filter not included — essential for protecting your new boiler from sludge. Always included in our price.
• Chemical flush not included — cleans your existing system before connecting the new boiler. Included in our price.
• Old boiler disposal charge — some companies charge extra to remove your old boiler. We include this in our fixed price.
• Warranty registration fee — we register your warranty for you at no extra charge.

Repair or Replace? When Does a New Boiler Make Sense?

A new boiler is a significant investment — so how do you know when it's worth it rather than repairing your existing boiler?

• Boiler is over 12 years old — older boilers lose efficiency significantly. A modern A-rated boiler can save hundreds of pounds annually on gas bills.
• Repair costs more than 50% of a new boiler — if the repair is going to cost £800 or more, a new boiler from £1,699 with a 10 year warranty is usually better value.
• Multiple recent breakdowns — if you've needed two or more repairs in a year, the boiler is reaching the end of its life.
• Parts no longer available — older models can't always be repaired because parts have been discontinued.
• Rising gas bills — if your heating bills have been increasing, an inefficient old boiler is often the cause.

Our engineers will always give you an honest assessment — we'll tell you if a repair is the right answer, and we'll tell you when a new boiler is genuinely the better investment.
