A complete guide to the grants, schemes, and financial incentives currently available for solar panels, battery storage, and renewable energy installations in the UK.
VAT Relief on Solar and Battery Installations
One of the most significant financial incentives for homeowners is the 0% VAT rate on domestic solar panel and battery storage installations. Introduced in 2022 and extended through to at least March 2027, this means you pay no VAT on the supply and installation of solar panels, battery storage systems, and other energy-saving materials for residential properties. On a typical £6,000 solar installation, this saves you £1,200 compared to the standard 20% VAT rate. This applies to all domestic installations carried out by MCS-accredited installers like GM Electrical Services.
Smart Export Guarantee (SEG)
The Smart Export Guarantee requires licensed energy suppliers to offer a tariff for surplus electricity you export to the grid from your solar panels. While rates vary between suppliers, you can typically earn 3-15p per kWh for exported electricity. Some suppliers offer fixed rates, while others offer variable or time-of-export rates that pay more during peak demand periods. To be eligible, your installation must be carried out by an MCS-accredited installer and your system must be 5MW or less. You can switch SEG tariffs at any time, so it is worth comparing rates regularly.
ECO4 and the Great British Insulation Scheme
The Energy Company Obligation (ECO4) scheme and the Great British Insulation Scheme provide funding for energy efficiency improvements, including solar panels in some cases, for eligible households. These schemes are targeted at low-income households, those on certain benefits, or properties with low energy efficiency ratings (EPC band D or below). Eligibility depends on your specific circumstances, and the measures available vary by energy supplier and local authority. Contact your energy supplier or local council to check if you qualify.
Local Authority and Community Grants
Some local councils and community energy organisations offer additional grants or interest-free loans for renewable energy installations. Availability varies significantly by area and funding period. In Lancashire and the North West, it is worth checking with your local council, the Lancashire County Council energy pages, and community energy groups for any current schemes. These grants can sometimes be combined with other incentives to further reduce the upfront cost of a solar or battery installation.
Business and Commercial Incentives
Businesses investing in solar PV can benefit from capital allowances, allowing them to deduct the full cost of the installation from their taxable profits in the year of purchase. The Annual Investment Allowance (AIA) covers solar installations, and larger businesses may also benefit from the full expensing scheme for qualifying plant and machinery. Combined with reduced electricity costs and potential SEG income, commercial solar installations can deliver a strong return on investment. VAT rules for commercial installations differ from domestic — speak to your accountant for specific advice.
Financing Options
If the upfront cost is a barrier, several financing options can help. Many installers offer interest-free payment plans that spread the cost over 12-24 months. Green home improvement loans from high street banks offer competitive rates specifically for renewable energy projects. Some homeowners use remortgage or equity release to fund larger installations. At GM Electrical Services, we can discuss the options available and help you find the most cost-effective route to solar ownership.
