If you are considering buying an oil boiler you will have to take into consideration the installation costs involved, as well as the running costs. Which? estimated that the average cost of oil heating for a three bedroom house was £1,044 in 2007-2008, compared to £568 for mains gas heating. However, an oil boiler could be a good alternative choice for the 4.3 million homes not connected to the UK’s gas network.

Are there any grants available to lower the cost of an oil boiler?

There are a few grants available to help out with oil boiler prices. Because new boilers are considered more environmentally friendly and efficient the government is keen to encourage them. The Warm Front Scheme will provide you with a package of insulation and heating improvements up to the value of £6,000 if oil heating is recommended. This is for low income families and other vulnerable households. However if you don’t qualify but are over 60 you could apply for the rebate scheme and get £300 back off oil boiler prices.

Trudy Chilcott says:

I am over 60 (d.o.b. 12.3.1952) – can I get any grant for a new oil
boiler – present oil boiler over 20 years old and no gas in the road?

samrat says:

Hi Trudy,
You might be eligible for a grant. To confirm, call Energy Saving Trust on 0300 123 1234 and they will be happy to help you.

Spud says:

A certain company assured me that I would qualify for a new replacement boiler and would not have to pay a penny as I am on pension credit. Finally, have now been told that the government has only allowed me a third off and will have to pay around 1300. I am not allowed to know how much I have been allocated nor the reason why I was not allowed the full replacement cost as ‘data protection’. Plus they want the money up front. not sure what to do.

Our contractors will only be able to advise and quote on private jobs therefore we recommend speaking to your local council who will be able to provide further advice on any grants available.

We hope this helps.
