Reduce you fuel bills by installing a Wireless Room Thermostat.
Most houses in the UK are using a central heating system powered by a boiler (gas, oil etc).
By installing a room thermostat and reducing the preset on your room thermostat by 1c degree, which would make a barely noticeable difference to the ambient temperature, you could save approximately 10% of your heating bills and reduce the wear and tear of the boiler.
