Consumer Incentives for Retrofit Upgrades: A Guide for UK Homeowners

Retrofit work is expensive, and several schemes pay for part of it. This is what is available in England and Wales, who each one is for, and what landlords now have to meet. Checked against gov.uk on 9 October 2026.

Government Incentives and Schemes

1. Boiler Upgrade Scheme: £7,500 towards an air source or ground source heat pump, £5,000 towards a biomass boiler and £2,500 towards an air-to-air heat pump, for owners of homes in England and Wales replacing a fossil fuel system. The installer claims it. Who qualifies and how it is paid.
2. Energy Company Obligation (ECO4): insulation and heating measures funded by energy suppliers for lower-income and vulnerable households. The scheme was extended by nine months and now ends on 31 December 2026, and the government has said there will be no successor supplier obligation (gov.uk, January 2026). The Great British Insulation Scheme closed on 31 March 2026.
3. Private rented homes: the government confirmed in its response to the 2025 consultation that privately rented homes in England and Wales must reach EPC C, or the equivalent under the reformed EPC metrics, by 1 October 2030, with a cost cap of £10,000 per property; the cost-cap exemption lasts ten years and most others five (gov.uk). A current EPC shows how far a property is from C and which measures count.

Key Challenges for Consumers

What the schemes do not solve:

• Awareness: the grant is claimed by the installer, so homeowners often first hear of it from a quote.
• Upfront cost: the grant covers part of the work, and the rest is paid before any saving arrives.

Social and Environmental Benefits

What the work changes in the house:

• Bills: less heat lost, so less fuel bought for the same room temperature.
• Comfort: insulation and a correctly sized heating system give steadier room temperatures and fewer cold spots.
• Emissions: lower, in line with the UK’s legal target of net zero by 2050 under the Climate Change Act.

Where to start

Every funded scheme starts with the same two documents: an EPC, which shows the property’s current rating and recommended measures, and for a funded retrofit a retrofit assessment under PAS 2035, which the scheme uses to decide what it will pay for. Inter Infinity carries out both across London and Kent.
