With energy prices continuing to fluctuate and expected to rise again by up to 20% in July, more homeowners are looking for ways to reduce their energy costs long term. One of the most popular home improvements is solar panels. Across the South East and East Anglia, thousands of households are investing in solar PV systems to reduce their electricity bills, improve their energy independence and lower their carbon footprint.
One of the most common questions homeowners ask is:
“How much do solar panels cost in the UK?”
In this guide, our team at SolarTherm UK explains the typical costs of residential solar panels systems in 2026, what affects pricing, how much you could save and what to look for when choosing a trusted installer.
Average Cost of Solar Panels in the UK
The cost of solar panels in the UK depends on several factors, including the size of the system, the type of panels used, roof complexity, and whether battery storage is included.
For a typical residential property, average prices are currently:
| Property Size | Recommended System Size | Estimated Cost |
| 1-2 Bedroom Home | 2kW – 3kW | £4,000 – £6,000 |
| 3 Bedroom Home | 4kW – 5kW | £6,000 – £8,500 |
| 4+ Bedroom Home | 6kW+ | £8,500 – £12,000+ |
These figures are general estimates and can vary depending on installation requirements and product specifications.
What Affects the Cost of Solar Panels?
- System Size: larger systems generate more electricity but require more panels and equipment. Homes with higher electricity usage often benefit from larger systems to maximise savings.
- Solar Panel Quality: premium solar panels typically offer higher efficiency, better low light performance, longer warranties and improved long term reliability. Choosing quality components can improve system performance and lifespan over time.
- Roof Type and Installation Complexity: factors that can affect installation costs include roof height and pitch, scaffold requirements, tile type, cable routing and shading from neighbouring buildings and tress. Properties across the South East and East Anglia vary significantly in roof design, so professional surveys are essential for accurate pricing.
- Battery Storage: adding battery storage allows homeowners to store surplus electricity generated by their panels during the day for use in the evening. While batteries increase upfront costs, they can significantly improve self-consumption rates and energy independence, resulting in even lower bills. Typical battery storage systems can add between £2,500 and £8,000 depending on capacity and technology.
Are Solar Panels Worth It in the UK?
For many homeowners, solar panels are now considered a strong long term investment. Benefits include:
- Reduced electricity bills
- Protection against rising energy costs
- Lower carbon footprint
- Increased property appeal
- Potential earnings through the Smart Export Guarantee (SEG)
Many households in the South East and East Anglia can generate a substantial proportion of their daytime electricity usage from solar energy, particularly during spring and summer months.
How Much Can You Save?
While savings can be affected by a number of factors such as system size, electricity usage patterns, battery storage and energy tariffs, a typical residential solar PV system could reduce costs by £600-£1,200 per year. Homes that use more electricity during daylight hours often achieve the highest financial benefits.
At SolarTherm UK your system is designed bespoke to your property and you will get a clear projection of expected savings year by year over a 30 year period.
How Long Does It Take Solar Panels to Pay for Themselves?
Most residential solar systems in the UK now achieve payback within approximately 6-10 years, depending on energy prices and household consumption patterns.
Considering that modern solar panels often carry performance warranties of 25 years or more, many homeowners benefit from decades of reduced electricity costs after the system has paid for itself.
