Solar panel installers

Prepare a useful solar PV enquiry

Start with your postcode, property type, electricity consumption and any plans for a battery, electric vehicle or heating changes. Ask installers to assess roof orientation, shade, access and the electrical installation before recommending equipment. Solar PV produces electricity, whereas solar thermal supplies heat for hot water. Tell the company which technology you need.

Compare designs on the same assumptions

Request the proposed panel capacity, inverter model, estimated annual generation and the assumptions used for shading and household consumption. Ask how much output is expected to be used in the property and how much could be exported. Different assumptions about daytime consumption, tariffs and future electricity prices can make similar systems appear to have very different returns. Separate installation cost from estimates of future savings.

Ask what the installed price includes

Compare access and scaffolding, mounting, electrical work, monitoring, commissioning, documentation and aftercare alongside the equipment. Check for roof repairs or other exclusions and ask who coordinates them. Request separate product and workmanship warranties. If considering storage, use our battery buying guide to compare usable capacity, power and retrofit requirements.

Export payments and installer checks

The Smart Export Guarantee is an export payment arrangement, not an upfront installation grant. Check supplier requirements and ask which documents the installer supplies. Confirm any certification claims against the relevant register; a directory entry is not approval. The Energy Saving Trust solar panels guide is a useful independent starting point.

Find installers serving your address

The records below are grouped by office location. An office in a town does not guarantee coverage of every nearby address, and a company based further away may serve it. Confirm your postcode and exact project before arranging a survey. For systems already installed, use repair and maintenance enquiries rather than assuming every new-installation business provides repairs.
