MCS Certified Solar Installers

Check the exact business and technology

Open MCS Find an Installer and search using the installer’s name or certification details. Verify the entry for solar PV and any storage work relevant to the proposal. Keep the date and evidence with your quotation.

The directory blocked our automated retrieval, so we do not claim to have checked any named installer’s live status. Ask MCS directly if an entry, certificate or entity name is unclear.

Certification is one part of due diligence

Read the installation scope, payment terms, aftercare and warranty documents independently. A certified business can propose different equipment or savings assumptions from another certified business. The directory does not choose the best economic design for your home.

Ask who carries out and commissions the job, which entity issues the paperwork and what records you receive. Treat a sales assertion about certification as something to verify, not a substitute for a directory check.

Export eligibility needs the supplier’s terms

The export supplier may request certification and other evidence. Check its current requirements before assuming an export payment in your financial estimate. Ofgem’s SEG guidance explains the scheme, while suppliers determine their actual product terms.

Network notifications or applications and planning matters remain separate checks. Ask the installer who handles each and what happens if a design needs alteration. A certification badge does not grant a particular export limit.

Turn the check into a comparable proposal

Combine certification evidence with the installer comparison checklist. Use the quote checker to record missing scope and warranty questions. Avoid treating absent information as proof of a failed installation; request written clarification first.
