Solar Panels
From £5,600
Based on 5.4kW array installed on tiled roof.
A properly sized solar array can cover a significant chunk of your electricity use — even in the north of Scotland. It's one of the most straightforward ways to reduce what you're paying to the grid.
All prices include installation, subject to survey.
0% VAT
Ends 31 March 2027
Planning a solar, a heat pump or battery storage installation?
Have it installed before 31 March 2027 and you'll pay 0% VAT.
From 1 April 2027 it's 5%, which is around £500 more on a £10,000 system.

Solar with Battery
From £11,965
Based on 5.4kW array installed on tiled roof with Tesla Powerwall 3 (13.5kWh) home battery
The most popular renewable energy combination for a reason — solar generates it, the battery stores it, and you're not paying for energy you've already made. Great for households who want to get the most out of every unit they produce.
All prices include installation, subject to survey.

Smart Tariffs
If you’ve got renewables installed in your home, the right tariff can make a real difference — from getting paid for exports to using energy when prices are lower.
