London Boiler Cashback Scheme

What is the London Boiler Cashback Scheme?

The London Boiler Cashback Scheme is a new initiative which debuted in 2016, and was introduced by the Greater London Authority aimed at reducing emissions in London. The scheme offers £400 cashback to private landlords and homeowners for installing a modern, high efficiency gas boiler in their London based home or property.

Emissions from homes currently account for 36% of all emissions in London, and the Government has identified that they can prevent nearly 10,000 tonnes of CO2 entering the atmosphere by replacing old, inefficient boilers with modern, high efficiency models.

Upgrading to a new, high efficient gas boiler will also reduce annual energy bills by £340 for participating households.*

Am I eligible?

In order to be eligible for a £400 cashback voucher the current boiler in your home or property must:

  • be 70% efficient or less
  • be gas, LPG, solid fuel or oil fired
  • be the primary heat source in the property
  • be installed in a house in one of the eligible London boroughs

The boiler will also need to be installed by a Gas Safe registered engineer who must sign the voucher.

If you're unsure if your current boiler is 70% efficient or less we recommend speaking to a local installer who will be able to identify your boiler's efficiency.

Which boiler should I replace my old one with?

Your replacement boiler must be a new, high efficiency model operating at 90% efficiency or more.
All Potterton boilers are A-rated for efficiency, meaning that they are eligible under the scheme. We have a model to suit most sizes of property.

Potterton is part of Baxi, who also offer a range of state of the art, highly efficient boilers and innovative heating  solutions for its customers.

How do I apply?

Private residential landlords and homeowners will need to complete the online application form. Following a successful application, the participant will receive a voucher for £400 cashback within ten days which must then be redeemed within 12 weeks.

As part of Baxi, we're supporting customers who are replacing their boiler under the London Boiler Cashback Scheme through the Baxi website. Baxi's Find an Installer tool will help you find a local heating engineer who will be able to help you choose the most suitable product for you from across our brands.
