Council eco buyback schemes can cost you nothing upfront but may reclaim 100% of the grant if you sell within 5 years
You may have seen offers from your local council for free or heavily subsidised home-energy upgrades like heat pumps or solar panels. These are often delivered through a council eco buyback scheme, which pays for the work upfront but attaches a legal condition to the property. If you sell your home within a set period, typically 5 to 10 years, you could be required to repay the full grant amount back to the council.
Council eco buyback schemes can save you hundreds a year on energy bills, but you may owe up to 100% of the grant if you sell within 5 years. Stay the full term to owe nothing.

The direct answer is that a council eco buyback scheme can save you hundreds of pounds a year on energy bills, but only if you remain in the property for the full buyback period. Sell early, and you may owe a pro-rata repayment that could reach 100% of the grant in the first year, as set out in the Department for Energy Security and Net Zero (DESNZ) guidance for the Local Authority Delivery scheme (DESNZ, 2026).
How a council eco buyback scheme works in practice
A council eco buyback scheme is a legal agreement in which the council funds an energy-efficiency measure, such as loft insulation, a heat pump, or solar panels, in your home. In return, you agree to repay the grant if you sell the property within a specified “buyback period,” which typically runs from 5 to 10 years. The repayment amount is usually a fixed percentage of the grant value, reducing each year you remain in the home, as detailed in the DESNZ Local Authority Delivery scheme guidance on grant recovery (DESNZ, 2026).
The scheme is designed to prevent “grant flipping,” where homeowners pocket the upgrade value without living with the energy savings. By attaching a legal charge to the property, the council ensures that the public money is used to deliver long-term energy savings. If you stay in the home for the full buyback period, the charge is removed and you owe nothing.
Eligible measures and typical grant values for 2026
Eligible measures under council eco buyback schemes in 2026 include loft insulation, cavity-wall insulation, solid-wall insulation, air-source heat pumps, ground-source heat pumps, solar photovoltaic (PV) panels, and solar thermal systems. Typical grant values range from £2,000 for basic insulation to £15,000 for a full heat-pump installation, according to the Energy Saving Trust (Energy Saving Trust, 2026).
The scheme is means-tested in some councils, targeting low-income households or those in fuel poverty. Ofgem’s Energy Company Obligation (ECO4) scheme also sets eligible measures and grant amounts, with many councils using similar criteria (Ofgem, 2026). You will need to check with your local authority to see if you qualify.
Quick numbers typical costs, savings, and payback
| Measure type | Typical grant cost (GBP) | Annual energy bill saving (GBP) | Buyback period (years) | Payback to council if sold in year 1 |
|---|---|---|---|---|
| Loft insulation | £2,000 | £200 | 5 | £2,000 |
| Cavity-wall insulation | £2,500 | £250 | 5 | £2,500 |
| Solid-wall insulation | £10,000 | £600 | 10 | £10,000 |
| Air-source heat pump | £12,000 | £800 | 10 | £12,000 |
| Solar PV (3.5 kW) | £5,000 | £400 | 5 | £5,000 |
These figures are based on typical savings data from the Energy Saving Trust (Energy Saving Trust, 2026) and clawback schedules from DESNZ (DESNZ, 2026). Actual savings depend on your home’s size, insulation levels, and heating usage.
What happens if you sell your home during the buyback period
If you sell within the buyback period, the repayment is calculated as a pro-rata amount of the original grant, minus a deduction for each full year you have lived in the home. For example, a 20% reduction per year means that after 3 years you would owe 40% of the grant. The repayment is typically secured as a legal charge on the property, meaning it must be settled at completion of the sale, as explained in the DESNZ guidance (DESNZ, 2026).
Some councils allow a grace period, such as 12 months, if you move due to unavoidable circumstances like job relocation or bereavement. You should check the specific terms of your agreement with the council before signing, as outlined in GOV.UK advice on selling a property with a grant charge (GOV.UK, 2026).
The direct answer will a council eco buyback scheme save you money overall?
Yes, if you stay in the home for the full buyback period, the energy savings — typically £200 to £800 per year — will exceed the grant value within 5 to 10 years, based on Energy Saving Trust data (Energy Saving Trust, 2026). If you sell early, you may owe a substantial repayment, but the energy savings you enjoyed while living there still count as a net benefit.
The scheme is most cost-effective for households that plan to stay in the property for at least 5 years. DESNZ’s cost-benefit analysis for the Local Authority Delivery scheme confirms that the energy bill reductions typically offset the grant value over the buyback period (DESNZ, 2026). For shorter stays, the scheme may still be worthwhile if the energy savings are significant, but you should factor in the potential repayment.
Eligibility, certification, and how to verify a council scheme installer
To qualify for a council eco buyback scheme, you must live in a participating local authority area and meet the council’s eligibility criteria, which often include a household income below £31,000, receipt of certain benefits, or living in a property with an EPC rating of D or below. Installers must be certified under the Microgeneration Certification Scheme (MCS) for heat pumps and solar PV, and under TrustMark for all insulation and heating measures, as per the DESNZ installer requirements (GOV.UK, 2026).
You can verify an installer by checking the MCS register at mcscertified.com (MCS, 2026) or the TrustMark database at trustmark.org.uk (TrustMark, 2026). Always confirm that the installer is approved for the specific measure you are receiving, as using an uncertified installer could invalidate the grant and leave you liable for the full cost.
