Typically highly efficient fuel with a good return on every unit of energy

Modern oil boilers are generally condensing and are 90% or more efficient

Floor standing options meaning they don’t need to be wall mounted

Oil boilers can be external, so they don’t take up space in your house

A lot of the costs of installing an oil boiler is determined by your current situation amongst other factors so to get an accurate price you’ll need a surveyor to come to your home.

Below is a breakdown of some factors that need to be considered when determining the cost of your boiler installation:

• Swapping a boiler that is like for like, such as a combi/combi boiler swap, is typically the price is cheaper as it’s easier to install.

• If there is building work involved in the installation, then it usually costs more

• Installations can also include buying extra parts such as new pipes which could add to the cost.

• Moving the boiler to another room or externally / internally will also usually increase the price.

• If you require an oil boiler then it’s usually because you live in a rural area, which can raise the price of installation as there may not be a local installer or they could be in high demand, but this is dependent on a host of different circumstances.
