This has been calculated by the Energy Saving Trust, and is based on a household having the oldest, least-efficient boiler possible for a three-bedroom, semi-detached house. In reality, if your boiler was installed in the late 1990s or early 2000s, youâre more likely to save half of that. With the average price of a new boiler installation being approximately Â£2,300, and energy providers quoting closer to Â£3,000, the fuel savings are likely to be small in the short term.
