In detail
Solar panel and battery costs in Scotland depend on your home, your roof and your energy usage. This page explains what you can expect to pay in 2026, what affects the cost, and how you can spread it with interest-free credit.
What affects the cost of solar panels and batteries?
The cost of a solar PV and battery installation depends on several factors that are unique to your home. The size and orientation of your roof determines how many panels you can fit and how much they generate. Shading from chimneys, trees and neighbouring buildings reduces output and may require a larger array. The capacity of the battery you need depends on your household usage — a larger family with high evening consumption needs a bigger battery than a single occupant who is out during the day. The condition of your electrical consumer unit and whether it needs upgrading affects the work involved. Scaffolding is required for most roof installations, and access difficulty adds to the cost. Every one of these factors is assessed during a no-obligation survey, which is why we provide a written quote rather than a generic price.
Typical installed price ranges (October 2026)
The following price ranges are typical installed costs at 0% VAT, sourced from bestbuilders.co.uk in September 2026. A 4kW solar PV system with a 5kWh battery typically costs £8,000–£11,500 installed. A 6kW solar PV system with a 10kWh battery typically costs £12,500–£18,500 installed. These ranges cover the system, installation, scaffolding and commissioning, but your actual quote may fall outside these ranges depending on your specific circumstances. The only way to get an accurate price is a survey of your home.
How does 0% VAT work?
0% VAT applies to the installation of solar panels and battery storage for residential properties until 31 March 2027. This means the price you are quoted is the price you pay — there is no 20% VAT added on top. This is a significant saving. After 31 March 2027, standard VAT rules would apply, but any quote we provide will set out the position at the time. The 0% VAT rate is already reflected in the typical price ranges above and in every quote we provide.
Can I spread the cost?
Yes. 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 your solar PV and battery installation over time without paying interest. Your quote sets out both options — paying the balance in full or spreading the cost — so you can compare and choose what suits you. There is no obligation to use finance. We do not quote monthly figures online because those depend on the system quoted and your individual circumstances.
What is included in a quote?
A quote from us includes the solar PV panels sized to your roof, a battery storage unit matched to your usage, an inverter, a generation meter, all wiring, scaffolding and access where required, and installation through MCS-certified partners and commissioning. The quote also shows how monthly payments could work if you choose to spread the cost. Everything is included in the total — there are no hidden extras.
Why don't you publish fixed prices online?
Publishing a single price would be misleading because every home is different. A meaningful quote requires a survey of your roof, shading, electrical setup and usage. Two homes on the same street could need different systems because of different roof orientations or shading. Instead, we survey your property at no obligation and provide a written quote that reflects your actual home. This keeps the quote accurate and means there are no surprises later.
How do I get an accurate quote?
The simplest way is to fill in our quote form or call us. We arrange a no-obligation survey at a time that suits you. The surveyor assesses your roof, shading, electrical setup and energy use, and we then provide a written quote showing the recommended system and how monthly payments could work. There is no pressure to proceed at any stage. For more on how the process works, see our how it works page, or read our full costs guide.
