The UK Government says up to five million homes could receive energy upgrades by 2030 under its Warm Homes Plan, a long-term programme intended to reduce household energy costs and expand access to technologies including solar panels, heat pumps and insulation.
The scheme is designed to apply across different housing types and tenures, covering owner-occupiers, private renters and social housing residents. According to the Government’s Warm Homes Plan, the programme includes direct support for households on lower incomes alongside grants, finance schemes and new standards for rented homes.
The announcement comes as households continue to face pressure from energy costs and as questions remain over how upgrades will be delivered in practice. Guidance published with the plan indicates that support and eligibility will vary depending on household circumstances and the type of property involved.
Different Routes for Homeowners and Tenants Seeking Upgrades
For households trying to understand what the programme means in practical terms, the first steps differ depending on whether they rent or own their home.
Sustainability expert Simon Bones said tenants should begin by checking the Energy Performance Certificate (EPC) rating of their property and speaking with their landlord if the rating is D or below. Homeowners, meanwhile, were advised to explore retrofit assessments to understand likely costs, opportunities and potential returns before deciding whether to proceed.
According to the Government’s policy paper, households receiving direct support are expected to receive home upgrades through tailored packages that could include combinations of solar panels, batteries, clean heating and selected insulation measures. The plan also outlines continued use of existing schemes for lower-income households before integrating them into a broader programme in later years.
Those able to fund improvements independently may still access support through existing incentives. The Boiler Upgrade Scheme remains available to eligible households in England and Wales and continues to offer grants towards installing qualifying heating technologies.
Shift in Focus from Insulation Towards Energy Technologies
One of the notable changes outlined in the policy direction is a broader emphasis on technologies intended to lower energy use over time rather than prioritising insulation alone. Bones said the approach marks a move away from earlier “fabric-first” strategies focused mainly on insulation and places greater emphasis on solar panels, batteries and heat pumps. Loft and cavity wall insulation remain part of the programme where appropriate, particularly where those measures offer stronger returns.
According to the Warm Homes Plan, the Government expects rooftop solar to be installed on up to three million additional homes by 2030 while supporting more than 450,000 heat pump installations annually. The policy also includes proposals for lower-cost borrowing through a new Warm Homes Fund and consumer finance measures intended to support upgrades across a wider section of households.
Bones added that financing costs remain a major factor because retrofit projects can typically cost between £10,000 and £20,000, meaning access to affordable borrowing could influence whether households decide to proceed.
