Cornwall Council adopted the Housing Decarbonisation Strategy for Cornwall on 13 November 2024, after gathering evidence on all housing types to find ways to cut emissions while keeping homes warm in winter, cool in summer and affordable to run1. The strategy sits alongside the council's existing Carbon Neutral Homes Programme, which was introduced under the climate action plan that followed its 2019 Climate Emergency declaration2.
The scale of the task is set out by the council: homes in Cornwall contribute 20.5% of total emissions, and over 90% of Cornish housing needs improvement if the county is to meet its carbon neutral ambition2. The council states that Cornish homes are "some of the oldest and leakiest in Europe", and that the array of building methods and materials used historically means they can be difficult to keep warm or cool, using more energy and costing more to run1. It also cites Building Research Establishment figures showing poor housing costs the NHS over £1 billion a year1.
The strategy's stated theme is that no one is left behind. The council says grant funding is not always available to everyone and that limited budgets mean it cannot pay for improvements to every home, so it looked at practical ways to support residents, including advice, online tools and signposting to alternative funding1.
"With this in mind a main theme of the strategy is that no one is left behind, so we looked at practical ways to support all of our residents."
One of those routes is the Green Home Improvement Loan scheme, introduced in April 20241. The council has also published case studies covering a 1930s family home, a 1950 semi-detached bungalow, a 1990s bungalow, a Victorian cottage and a 1970s house, along with the evidence reports used to develop the strategy1. A consultation on the draft strategy has closed1.
Separately, the Warm Homes Local Grant provides funding to local authorities to help low-income households in England improve energy efficiency and install low-carbon heating2. Upgrades may include:
| Measure |
|---|
| Air source heat pumps |
| Loft insulation |
| Double glazing |
| Solar PV panels |
In 2025, Cornwall Council received funding to be spent over three years, but the amount was less than expected, so there is a long waiting list2. The council also states that the Housing Renewal and Housing Adaptation policies have been replaced by a single Housing Assistance policy2.
Why it matters for households
For a household in Cornwall, the strategy is a statement of intent rather than a direct grant. The practical routes to money named in the council's own material are the Green Home Improvement Loan scheme, introduced in April 2024, and the Warm Homes Local Grant, which is administered through a government waiting list and is aimed at low-income households1. The council is explicit that funding is limited and that it cannot pay for improvements to every home1.
The relevance to energy independence lies in the fabric of the housing stock. A home that is hard to keep warm uses more energy to reach the same temperature, which ties a household more tightly to whatever it pays for that energy. The council's own figures put over 90% of Cornish housing in need of improvement, and note that Cornish housing is less energy efficient than housing in the South West and across the UK2. The strategy also covers older and historic buildings, with a document on adapting historic buildings for energy and carbon efficiency published alongside the evidence base1. Households in social or rented housing have separate standards to consider under Housing Quality Standards for Social and Rented Homes, while new-build performance is governed by the Future Homes Standard.
What happens next
The council says it will add to its Housing Decarbonisation pages as the strategy develops and invites residents to register or follow for updates1. The consultation survey on the draft strategy has concluded1. No further dated milestones beyond the 13 November 2024 adoption have been reported. The wider legal duty to decarbonise is set out in the Climate Change Act 20082, and the council's energy regulation and policy guide covers the framework that applies across the UK.
