‘Use 3 fills of oil a year and have an old boiler??? You could save £350 per year, and reduce your oil use by 1,000 litres’

It’s often only as the evenings shorten and the heating comes back on that we notice our energy bills starting to rise. But thinking through your options when the sun is (hopefully) shining means you can be all set to save when the cold months kick in.

In this blog we highlight what you need to consider in deciding whether its time to go for a new oil boiler. No-one likes the idea of forking out between £1k – £2.5k on a new boiler but the annual savings and support available may mean it is the right decision. 

  • Got an Old Oil Boiler?
    Around 70% of homes use home heating oil – but many boilers have been installed for years, if not decades. If your boiler is more than six years old (and certainly if its ten or fifteen years old) it will be worth replacing with a modern condensing boiler. These boilers can have efficiencies of around 95% while older boilers may only be 60–65% efficient.

    An old oil boiler may be only 60%-65% efficient which means for every £100 spent on oil £35 – £40 is wasted.

  • How much could you save?
    A typical family home may use three oil fills (of 900litres) per year. If their boiler is fifteen years old, and only 60% efficient then moving to a new oil condensing boiler would make a lot of sense. They could save almost £350 per year and reduce the amount of oil they use by around 1,000 litres

  • Cost of replacing your boiler and what help is available?
    A new boiler can cost between £1,180 and £2,410 depending on what you need for your home. There are a range of grants to help with the cost – the boiler replacement scheme can provide up to £1,000 towards the cost of installing an energy-efficient condensing oil boiler. For more information see our Energy Advice Centre – Boiler-Replacement-SchemeMany installers and manufacturers also offer 0% interest free loans.


  • Getting the Work Done
    For oil boilers you should only use an OFTEC registered installer.  OFTEC keeps a register of all suitably qualified, reputable oil engineers. So when you choose an OFTEC registered technician you will have peace of mind that the engineer is trained, qualified and accredited to do the work.
