Free home upgrades reach more households in Cumberland

More than 1,200 households in Cumberland have received free energy-saving upgrades this year, a 40% increase on the same period in 2023. The data, released by Cumberland Council, tracks the rollout of the Energy Company Obligation (ECO4) scheme, which requires the UK’s largest energy suppliers to fund insulation, heating, and solar installations for low-income and fuel-poor homes.

As reported by Cumberland Council, the typical household receiving upgrades has an annual income below £31,000 and lives in a home with an EPC rating of D or lower. For those households, the savings are immediate: a fully insulated home can cut heating bills by £200–£400 a year, according to Energy Saving Trust estimates. For a 3-bed semi using 12,000 kWh of gas, that is roughly a 15–25% reduction.

Who qualifies, and who doesn’t

ECO4 is not universal. It targets households on means-tested benefits such as Universal Credit, Pension Credit, or Child Tax Credit, or those referred by a local authority or a health professional. The scheme also covers properties with an EPC rating of D, E, F, or G, the worst-performing homes. Owner-occupiers and private tenants are eligible, but landlords must contribute up to one-third of the cost for rental properties.

The catch is that not every home qualifies. A household with an EPC rating of C or above is excluded, even if income is low. And the scheme only covers upgrades that meet a minimum cost-effectiveness threshold, so a listed building or a flat with no loft may not be eligible for cavity-wall or loft insulation. Ofgem, which oversees ECO4, reported in its 2024 annual review that around 15% of applications are rejected on technical grounds.

What it costs a typical household

For qualifying households, the answer is zero. The entire cost, typically £5,000–£15,000 per home for a full package of insulation, boiler replacement, and solar panels, is paid by the energy supplier, who recovers the cost through a levy on all domestic energy bills. That levy adds about £15 a year to the average dual-fuel bill, according to Ofgem’s latest breakdown. So even households that do not qualify are contributing, but at a fraction of the cost of a private retrofit.

For a household that pays £1,800 a year on energy, a £15 levy is less than 1% of the bill. The benefit to the 1,200 Cumberland households is a reduction of £200–£400, a net gain for the system as a whole, provided the upgrades are installed to a high standard. The UK government’s own impact assessment estimates that every £1 spent on ECO4 saves £2.50 in health and energy costs over the lifetime of the measures.

How to apply, and when

Applications are open until 31 March 2027, but the scheme is already oversubscribed in some regions. Households should start by checking eligibility on the Energy Saving Trust website or contacting their local council’s energy advice team. Cumberland Council, for example, runs a dedicated ECO4 referral service that handles the paperwork and arranges a free home survey.

Homeowners should be wary of doorstep salespeople offering ‘free upgrades’, legitimate schemes are managed through councils or approved installers listed on the TrustMark or PAS 2030 registers. Ofgem’s enforcement team has fined three suppliers this year for mis-selling ECO4 measures, including one that charged households for work that should have been free. If an installer asks for upfront payment, walk away.

The Cumberland data shows the scheme works, but only for those who know about it. With 3.2 million homes in England alone still rated EPC D or below, the gap between eligibility and take-up remains wide. For households that act now, the savings are real. For those who wait, the levy will keep rising, and the winter bills will keep coming.
