There are still millions of homes not connected to mains gas in the UK. And, that means using either LPG or oil.
In our 5-minute guide to new oil boiler installation costs, we’ll explain:
- The expected cost of a replacement boiler
- What things can affect the quotes you receive
- The best oil boiler brands
How Much Does A New Oil Boiler Cost?
An oil boiler can cost anywhere from £1,000-3,000. It depends on the size of your property, and the flue, extensions and elbows needed. To get the best deal, you can get free quotes here, and compare up to 3 different prices (including materials).

How Much Does Oil Boiler Installation Cost?
Oil Boiler Cost

When Will An OFTEC Engineer Charge Extras?
Not all installations are simple.
And, that’s why OFTEC engineers will price jobs on a case-by-case basis.
They simply can’t offer exact quotes without viewing the property.
Factors that might increase the cost of the installation include:
- Pipework needs to be re-rerun because it’s not up to standard
- You’re converting the central heating system (i.e. from a regular boiler, to a combi oil boiler installation)
- A magnetic system filter needs to be installed
- You want the boiler or cylinder moved to a new location.
How Much Does Oil Central Heating Cost To Replace?
If we’re assuming a 3-bedroom detached house with 10 radiators, a complete central heating installation will cost in the region of £4,500-5,500.
This assumes there is no pipework or radiators in the property currently.
Every section of pipework that is already in place will reduce the cost of the installation.
And, if there is a complete run of central heating pipe and all radiators present, the price of the installation only relates to a boiler swap (which we mentioned above should be around £3,000).
Don’t just agree to the first quote you get. Local installers tend to be much cheaper than national boiler installation companies. You can compare up to 3 oil boiler quotes for free here.
How Long Will An Oil Boiler Last?
Warranties are usually an effective way to gauge how long products last. Worcester tend to offer 7-9 years on their oil boiler range. But, some other reputable brands offer more.
For instance, Grant offer a 10-year guarantee on their Vortex Oil range.
That’s all just an indicator. We’ve been called out to replace oil boilers that are 20 years old, and have only just given up.
Want it to last beyond the guarantee?
Make sure you get an annual oil boiler service.
This won’t just prolong the life of your boiler, it will ensure an OFTEC engineer picks up on a potential problem, before it comes a real problem!
Types of Oil Boilers
Because of the size of oil boilers, many people prefer external over internal. These can be fitted outside.
A combination oil boiler installation works with a boiler only – no hot water tanks or cylinders.
It will heat up hot water on demand. It heats water as it passes through the boiler, rather than relying on a storage tank (and, that’s great news if you’re trying to save space).
There’s a tonne of boilers in the 18kW, 25kW and 32kW range. And, that’s good enough to heat a 4-bedroom property with 1-2 bathrooms.
Once you start going over the 32kw range (i.e you have a large property with 2 bathrooms), you’ll be looking at either a system or regular boiler.
A system boiler installation works in conjunction with a hot water cylinder. So, you turn on a tap and the shower, and they are fed from pre-heated water in the hot water cylinder.
In the case of the combi oil boiler mentioned above, the boiler simply wouldn’t be able to keep up with the hot water demand; whoever’s in the shower is about to get a nasty surprise!
A regular oil boiler installation will usually consist of the boiler, cylinder and a storage tank. And, that means you’re going to need a lot of space.
But, like the system boiler, it’s an excellent choice for properties where hot water demand is high.
Is A Combi, System Or Regular Oil Boiler The Best?
The answer really lies in your heating and hot water needs. And, that’s why we’d always suggest getting a qualified engineer to come and inspect the property.
As a general guide. Properties with up to 4 bedrooms and a maximum of 2 bathrooms will be fine with a large combination boiler.
Properties larger than this will work much more efficiently with a regular or system oil boiler.
