People too shy to pick up their toolbox and carry out simple DIY tasks have been told they may be missing out on savings.
A study on behalf of the Energy Saving Trust has found Brits could be saving a total of over £220 million and stopping 1.2 million tonnes of carbon dioxide from escaping by adding simple solutions like loft insulation.
Homeowners could save an average of £140 per year by investing a little time and money into energy-efficient tasks.
Putting a "jacket" on hot water cylinders can knock £40 off annual fuel bills, while adding loft insulation will save a further £60 per annum.
It also found a further £30 can be saved by draught-proofing doors and windows – something to bear in mind when choosing a conservatory provider.
People converting their loft may choose to have it insulated when installing a roof light to ensure the room stays warm.
A recent HSBC survey showed those who convert their attic space are likely to add over £13,000 to the value of their property.
