Upgrade to a more efficient boiler

The current lifespan of a boiler is around 15 years, so even in a modern home your central heating system could be well past its best before date. Your boiler accounts for around 60% of the carbon dioxide emissions if your home is gas heated. By fitting a new high efficiency condensing boiler and improving your heating controls, you will significantly cut your home's carbon dioxide emissions and could save yourself as much as £275 a year and keep on saving year after year.
