What’s The Average Cost For Boiler Installations?
Find out how to get a new boiler installed and how much it should cost. We’ll help make sure you don’t get overcharged for your boiler installation. Boiler installation costs vary depending on what work that is required, the parts needed, parts availability, where you live and who you employ for the job.
From our experience the average cost of installing a new boiler is between £1,500 – £5,000 depending on your specific needs and type of hot water system. There may be extra charges for changing existing pipework in the property. We will let you know if this work will be needed before starting work.
As well as paying for labour, the cost of your new boiler and system cleanse, we would always recommend that you consider adding a filter. This will keep your replacement boiler free of gunk long after the heating engineer has left. This should add £100 – £200 to the cost of your boiler installation.
Different Types of Central Heating Systems
Combi Heating Systems
Condensing boilers come in both combination and regular models. A combination (or ‘combi’) boiler will provide your central heating and produce hot water on demand, firing up when you turn on a hot tap in the kitchen or bathroom.
A regular boiler will do your central heating, but rather than produce hot water as and when required, it will heat a quantity of water which is held in a storage cylinder until required.
Some boilers only run the central heating and don’t provide hot water at all, in which case an electric immersion tank or another form of water heating is required.
A gas combi boiler system contains almost all components within the boiler itself, which makes the boiler system more compact and there’s no need for a cold water expansion tank in the loft. You can immediately get hot water on demand, which is really useful.
In a typical semi-detached property that uses mains gas for heating you can reduce your heating bills by around £300 per year if you upgrade from an old G-rated boiler (less than 70% efficient) to a new A-rated condensing boiler with full heating controls (e.g. timer/programmer, room thermostat and thermostatic radiator valves). The savings are even greater for larger properties and for heating systems that run on oil which is more expensive than gas.
A combi gas boiler system is better suited to a home with a smaller number of people, as you’ll only be able to use hot water from a combi boiler system for one task at a time. Which? have put a guide together on the best Combi boiler brands that may be useful.

Unlike a combi gas boiler system, an open-vented heat-only gas boiler system (with a water tank) has components housed externally from the boiler, such as a circulation pump. This type of system will also usually require cold water, as well as feed and expansion tanks in the loft.
With a heat-only boiler (also known as a conventional boiler system), the hot water is stored in a hot water cylinder or hot water storage tank. You will also normally have an on/off switch|so you can heat water in the storage tank when you know you are going to need it, and leave it switched off when not in use.
Heat-only boilers are better suited to larger households where several people frequently need to use hot water at the same time. They also require space for a cold water feed tank, usually in the loft.
They don’t give you hot water on demand, so you will have to wait for the water to heat up again once the storage tank runs out of hot water. If you run a bath, for example, you may have no hot water for a while afterwards.
Because you don’t get hot water on demand, they are a bit less efficient than combi-boilers, simply because you will gradually lose heat over time from the hot water cylinder. New pipework may be necessary if you’re replacing an old non-condensing boiler with a modern condensing one. Expect to pay between £200 and £300 for this.
Closed Vent Boilers
System boilers are the perfect choice if you don’t want external components. This is because a lot of these added components are built into the of the boiler. A system boiler still requires a hot water cylinder, but the feed and expansion tank is replaced by an expansion vessel in the boiler. This normally houses the circulation pump.
System boilers are excellent for large houses in Hampshire. These systems are designed for when hot water is required at several taps at a time. With this type of boiler you don’t need a big water tank in the loft, like you do with a conventional hot water system. System boilers are great if your premises are located in an part of Hampshire with weak water pressure.
