What is the Cleaner Heat Cashback Scheme?

Cleaner Heat Cashback Animation

Cleaner Heat Cashback is a £10 million commercial boiler scrappage scheme, offering a financial incentive to small and medium-sized businesses in London to replace their existing, inefficient boiler with a more efficient system helping to cut bills and reduce environmental impact.

The scheme, which is the first of its kind in the UK, will provide between 30 to 40 per cent cashback to SMEs when they replace older, polluting boilers with new, cleaner systems.

If you’re a small business in London and have an older, inefficient heating system you may be eligible for 30 to 40 per cent cashback when you replace it with a new, cleaner system.

Support is available on a first come, first served basis. So apply now to avoid disappointment!
