How Do Air Source Heat Pumps Work?
An ASHP extracts heat from the outside air, even in sub-zero temperatures, and transfers it into your home to provide efficient heating and hot water.
Why London Homes Are Switching to Heat Pumps
Switching to an Air Source Heat Pump (ASHP) in London is a smart, energy-efficient way to heat your home while reducing energy bills and carbon emissions. Here's why:
- Efficient Heating & Hot Water – Even in temperatures as low as -15°C.
- Lower Carbon Emissions – Uses renewable energy instead of fossil fuels.
- Reduce Energy Consumption – Uses less energy than traditional gas boilers.
- Government Grants Available – Eligible for the Boiler Upgrade Scheme (BUS).
- Increased Property Value – Energy-efficient homes are appealing to buyers and tenants.

Customer Reviews
What our London customers say:
"I recently purchased a house that had no heating system and was still running on coal. Infinity Energy Organisation carried out a full assessment and installed a complete modern, energy-efficient setup including Sunamp for hot water, an air-to-air heat pump system, solar panels, and battery storage. The results have been outstanding - in May 2026 my total energy bill was under £15. Their communication has been excellent throughout, and any questions I had were resolved quickly. I want to especially thank Adarsh and Romit for their support and professionalism. Highly recommended for anyone looking to modernise their home's energy system."
"We used Infinity to help us with achieving our green energy project. We liked their work ethics, no quibble customer support, efficient and considerate installers and excellent project management."
