Upgrade your Boiler and Save

There are many ways to save energy within your home,
and having an A rated boiler is a great place to start.

Upgrade an old Gas Boiler

Many homes on the Island running Gas central heating and hot water, are doing so using boilers as low as rated D grade. Simply upgrading to an A rated boiler can help you save hundreds of pounds over the year.

Save up to £970 per year


Switching from Oil to Gas

An old oil boiler can seem like it could last forever and this is often the case, however they are incredible inefficient meaning they burn more fuel than is necessary. D rated boilers with thermostat and no controls can be upgraded to an efficient A graded gas boiler with hundreds of pounds to be saved on the burning of unnecessary fuel.
