Discover the UK government incentives available for solar panels and battery storage systems. From the Smart Export Guarantee (SEG) to VAT relief, this guide explains how homeowners can maximise savings and reduce installation costs by taking advantage of these programmes.

Why government incentives matter for solar panel installation

Solar panels and battery storage systems offer significant long-term savings, but the upfront costs can feel like a hurdle for many homeowners. Fortunately, UK government incentives are designed to make solar energy more accessible and affordable. These programmes not only help reduce installation costs but also provide opportunities to earn money from excess energy generation. Understanding these incentives can help you make the most of your investment in solar and battery systems.

The Solar Export Guarantee (SEG)

The Smart Export Guarantee (SEG) is one of the key government-backed schemes designed to reward homeowners for generating clean, renewable energy. Introduced to replace the now-closed Feed-in Tariff scheme, the SEG ensures homeowners continue to benefit financially from exporting excess energy to the grid.

Here’s how it works:

  • Homeowners with solar panels can sell any surplus energy their system generates.

  • Energy suppliers with over 150,000 customers are required to offer SEG tariffs, with rates ranging from 4p to 15p per kWh, depending on the supplier.

  • Payments are typically made quarterly or annually, offering a consistent income stream.


For example, if your solar panels generate 1,500kWh of excess energy annually and your supplier offers a rate of 10p per kWh, you could earn up to £150 per year simply by exporting energy you don’t use.

To take advantage of the SEG, you’ll need to ensure your solar panel system meets the following criteria:

  • It must be installed by an MCS (Microgeneration Certification Scheme) accredited installer.

  • You need a smart meter capable of recording exported energy.

VAT relief on solar panel and battery installations

Another significant incentive is the reduced VAT on energy-saving equipment. Previously set at 5%, the VAT rate has now been reduced to 0%, offering homeowners a greater opportunity to save on solar installations.

This VAT relief applies to:

  • Residential installations, including new solar panels and battery systems.
  • Homes where solar panels are retrofitted or upgraded with battery storage.


For example, a homeowner installing a £7,000 solar panel system saves £1,400 immediately thanks to the VAT reduction, making the investment far more affordable. This incentive is expected to remain in place until 2027, meaning there’s never been a better time to invest in solar energy.

Beware of misleading ads about government cash grants, ‘free solar panels’ etc

Recently, we’ve heard from customers who have seen online ads claiming that the UK government is offering large cash grants for solar panel or battery storage installations. These ads often sound too good to be true – and that’s because, in most cases, they are.

While there are legitimate incentives like the Smart Export Guarantee and VAT relief, we are not aware of any government-backed cash grants for solar panel installations at this time. Ads suggesting otherwise are often a result of lazy marketing which uses misleading claims to attract clicks.

These ads may:

  • Exaggerate existing incentives – taking legitimate schemes like VAT relief or SEG and present them as cash handouts.

  • Rely on “too good to be true” tactics – if a claim seems unrealistic or lacks specific details, it’s worth approaching with caution.


To ensure you get accurate information about solar incentives, always rely on reputable sources, including government websites and trusted solar providers like us. If you’re unsure about a claim, feel free to reach out to us for clarification.

Financing options and local grants

In addition to national programmes like the SEG and VAT relief, some local authorities offer grants or low-interest loans to homeowners adopting renewable energy technologies.

For example, local councils may provide financing for energy-efficient upgrades through the Home Energy Scotland Scheme (in Scotland) or other regional programmes. These schemes help cover a portion of the costs for installing solar panels and battery storage.

Homeowners should check with their local authority to see if funding or financing options are available in their area. Many of these programmes are limited-time opportunities, so acting sooner rather than later can ensure you don’t miss out.

How these incentives impact your ROI

Government incentives directly improve the financial benefits of investing in solar panels and battery storage. Here’s a summary of how they impact your return on investment (ROI):

  1. Reduced installation costs – the 0% VAT rate significantly lowers upfront costs, immediately reducing your financial outlay.

  2. Additional income from SEG – exporting excess energy provides a consistent return, further shortening your payback period.

  3. Access to local grants and financing – regional schemes can reduce costs even further or spread payments over time.

For many UK homeowners, these incentives make solar energy systems far more affordable while improving overall savings. When combined with the natural long-term benefits of solar panels and batteries – such as energy independence and protection against rising energy prices – these schemes ensure you get the best possible ROI.

Is now the time to go solar?

With generous government incentives, lower installation costs, and rising energy prices, there’s never been a better time to invest in solar energy. The 0% VAT rate and Smart Export Guarantee offer immediate financial benefits, while regional grants and financing options provide additional support for homeowners looking to make the switch.

By taking advantage of these programmes, you can lower your upfront investment, earn money through energy export, and maximise long-term savings. Whether you’re installing solar panels for the first time or upgrading your system with battery storage, these incentives ensure you see real financial and energy benefits.
