What is included in a solar panel installation quote?
A legitimate solar quote should be written, itemised, and include the panel brand and model, inverter type, system size in kWp, estimated annual generation, total installed cost, warranty terms and a proposed installation date. If any of these are missing, ask for them in writing before proceeding. You can use our Solar Buyer's Guide to compare quotes side by side.
Every installation through our MCS-certified partners includes MCS certification, G98/G99 DNO notification and SEG registration as standard — not as optional extras. This is important because without MCS certification you cannot register for Smart Export Guarantee payments or access most funded schemes.
How does system size affect the cost?
Solar panel systems are priced per kWp (kilowatt peak). A larger system costs more in total but less per kWp because the scaffolding, installation labour and paperwork are spread across more panels. A 4kWp system (roughly 8-10 panels) suits a typical three-bedroom home. Smaller properties may suit a 3kWp system, while larger homes or those with high daytime usage may benefit from 6kWp or more.
The right size depends on your roof area, orientation, budget and electricity usage. Your installer partner will assess this during a site survey and recommend a system size in writing.
How much does battery storage add?
Battery storage lets you use your solar generation in the evening instead of importing from the grid. A typical home battery with 5-10kWh of capacity adds around £2,500 to £5,000 to the installation cost, depending on capacity and brand. Not every property needs a battery — if you are home during the day and use most of your solar generation directly, the benefit is smaller. See our battery storage guide for more detail.
Is 0% VAT still available in 2026?
Yes. The UK government's 0% VAT relief on qualifying solar PV, battery storage and heat pump installations runs until 31 March 2027. The installation must be carried out by an MCS-certified installation company and meet the eligibility criteria. This reduces the total cost compared to the standard 20% VAT rate.
Can I pay monthly for solar panels?
Interest-free credit up to £30,000 is available, subject to status and affordability. Terms and conditions apply. This means you can spread the cost of a solar installation over monthly payments without paying interest on the balance. Full finance terms are confirmed in writing for your specific installation before you sign anything.
We do not advertise specific APRs, lender names or monthly payment amounts on this website because those depend on your individual circumstances. Call 0141 230 0198 to discuss finance options for your property.
What about commercial solar costs?
Commercial solar installations benefit from economies of scale — larger roof areas mean lower cost per kWp. Warehouses, farms, offices and industrial units can see significant reductions in daytime electricity costs. For commercial pricing, see our commercial solar page or call us to discuss your premises.
What grants or funding are available?
Interest-free credit up to £30,000, subject to status, is the main finance option we discuss. Funding schemes and eligibility criteria change over time, and we do not publish specific grant figures on this website. Always check current eligibility before making decisions. An MCS-certified installation is typically required for any funded scheme.
How do I get an accurate price for my home?
The only way to get an accurate price is a site survey from an MCS-certified installer. Online estimates can give a rough idea but cannot account for your roof structure, shading, orientation or electrical setup. Submit your postcode through the form on this page or call 0141 230 0198 and we will connect you with an MCS-certified installer partner for a written, itemised quote.
