People looking to switch gas provider in order to get cheap energy bills may find they can cut the amount they spend by fitting insulation.
It was stated by British Gas that without this, much of the warmth a home generates will be lost, so improving this area is one of the best things people can do to reduce their expenditure on heating.
As well as installing loft and cavity wall insulation, the firm suggested a person should check their property for any potential leaks in areas such as windows, vents and letter boxes.
"If your doors [or] windows need substantial work, then it is advisable to seek the help of a professional. If [the] frames are wooden and have warped from their original shape, you may need to reinstall them," the company said.
Customers who have deals with the energy supplier may also be able to benefit from a free insulation scheme run by the firm, provided they apply before December 22nd.
A similar programme is being run by EDF Energy, which stated it will provide loft and cavity wall lagging to all its customers.
