Solar Thermal Installers in Cumbria

Check that the installer is MCS certified. A good installer should assess your hot water usage and recommend the right collector size (typically 2–4 panels for a family home). Compare at least 2–3 quotes in Cumbria, ask for references, and verify they have experience with solar thermal specifically — not just solar PV.

A typical solar thermal installation in Cumbria costs £3,000–£5,500 depending on whether you choose flat plate or evacuated tube collectors and whether a new hot water cylinder is needed. There is currently no direct government grant for solar thermal. Evacuated tubes (e.g. Thermomax, Kingspan) cost more but perform better in UK weather.

Not all installers are MCS certified. Using an MCS-certified installer ensures quality and compliance with standards. MCS maintains a public register at mcscertified.com. On this page, all listed installers serve Cumbria. Look for the “MCS Certified” badge on each listing.

In most cases, yes. Solar thermal requires a twin-coil hot water cylinder — one coil for the solar circuit and one for your backup boiler. If your existing cylinder only has a single coil, it will need to be replaced. A new 300-litre twin-coil cylinder typically costs £400–£700 as part of the installation. Ask your installer whether a new cylinder is included in the quote.

A well-sized solar thermal system typically provides 50–70% of your annual hot water needs. In summer months (May–September), solar thermal can meet nearly all your hot water demand. In winter, your backup boiler or immersion will cover the shortfall. A typical family of 4 needs a 2–4 panel system with a 200–300 litre cylinder.
