Mayor of London seeks to banish biomass from business in new scrappage scheme

New Cleaner Heat Cashback scheme offers SMEs incentive to replace commercial biomass boilers ‘of any age’

London’s new commercial boiler scrappage scheme includes a specific provision to replace biomass boilers of any age, as part of the Mayor’s campaign to improve air quality in the capital.

The Cleaner Heat Cashback scheme - see main story below - offers an incentive of 30-40 per cent cashback to SMEs to upgrade to a new low-NOx boiler. But whereas gas, oil or LPG boilers have to be over 10 years old to qualify, there is no age criteria for biomass or coal boilers, in a clear move to reduce what is viewed by the Mayor as more heavily polluting technology.

The Mayor’s office said: ”Biomass fuels produce more air pollutants compared to the other technologies eligible under the scheme, therefore we are not supporting the installation of new biomass boilers.”

The scheme’s rules also require the biomass boiler to be replaced with a renewable technology, such as a heat pump or solar thermal, rather than a gas boiler.

Similarly, oil boilers cannot be replaced with more efficient oil boilers, they have to be replaced by other technology.
