Switching from a conventional boiler to one of the new condensing models will result in substantial savings for householders, according to Switch with Which?.
It says that replacing an old boiler with a new, energy efficient condensing model will more than pay for itself over the years.
For example, the Which? Best Buy Potterton Gold C24 HE combination condensing boiler costs £800. But compared to older models, a modern condensing boiler could cut your gas bills by between £160 and £360 per year depending on the size of your house.
Older boilers tend to lose heat through the flue, wasting nearly 40% of energy in gas.
Not only does this lead to higher bills, it also means an increase in greenhouse gases.
Mike Stevenson, Head of Marketing at Switch with Which? added: ‘If splashing out on a new boiler before Christmas just isn’t realistic, though, it doesn’t cost a penny to check you’re on the best deal for your heating bills, and switch to a better deal if you’re not.
‘People who have switched through Switch with Which? are enjoying great average annual savings of over £200 per year on their energy bills, and switching now will let you reap the full benefits by the time you have to turn the radiators up.’
