Question to the Department for Business, Energy and Industrial Strategy:

To ask Her Majesty's Government how many domestic boilers they anticipate will be sold every year for the next 10 years; and what they estimate the carbon emissions for those boilers will be.

There are close to 2 million heating appliances sold in the UK each year, over 80% of which are domestic gas boilers. Gas boiler sales are likely to remain at a similar level in the immediate future. However, industry projections for heating appliance sales in 2020 are being revised due to the impact of covid-19.

Emissions from individual homes depend on the size and energy efficiency of the property. As a result of minimum energy efficiency requirements for new gas boilers, introduced in 2018, the average household that switches from an average gas boiler can save 200kgCo2 per year.

The Government is committed to reducing the emissions produced from heating our homes by increasing energy efficiency and utilising clean heating technologies to meet our net zero commitments. The immediate steps to tackle these emissions will be set out as part of the Heat and Buildings Strategy, which we aim to publish later in the year.
