What Are Heat Pumps and Why Should You Consider One?
A heat pump works by extracting ambient heat from the outside air and using it to provide heating and hot water, even in cold weather. Working well even in cold temperatures, heat pumps can also offer:
- Lower carbon emissions compared to traditional boilers
- Reduced running costs
- Eligibility for government grant funding
- Quiet, reliable operation
- Long lifespan with minimal maintenance

Your Heat Pump Questions Answered
Here are answers to some of the most common questions we receive about our heating, solar, and renewable energy installations.
A heat pump extracts heat from the outside air, even in cold weather, and uses it to warm your home and hot water. It works much like a fridge in reverse, using a small amount of electricity to move heat rather than generate it directly.
Most homes are suitable for a heat pump, but it depends on factors like insulation, available space for an outdoor unit, and existing heating emitters. Our engineers carry out a full heat loss survey to confirm suitability before installation.
A typical air source heat pump installation takes 2 to 3 days. More complex projects, such as full system replacements including radiator upgrades and cylinder installation, may take 4 to 5 days.
Yes. The Boiler Upgrade Scheme currently offers £7,500 for both air source and ground source heat pumps in England and Wales, and is confirmed available until at least 2027. LGS handles the application process on your behalf.
Good insulation improves heat pump performance, but it is not a blanket requirement for the BUS grant. LGS carries out a full heat loss survey to confirm suitability and advise on any upgrades before installation.
