"What a superb Company from start to finish… The standard of work is excellent. Everything was done when it was scheduled to be… Probably the best tradesmen's work I have ever had done."
"Brandon was really knowledgeable and helpful with the various options and quotes - and there was no pressure to purchase - but the quotes were very competitive… The post install after service has been great too, and they have followed up to make sure everything is running as expected…"
"From the initial survey right through to installation and aftercare, the team were professional, knowledgeable, and friendly… It was important for us to choose a trusted local business, and Mercia Electrical proved we made the right decision."

Yes. Mercia Electrical is MCS certified, NICEIC approved and TrustMark registered. MCS matters for solar because it's what lets you receive export payments under the Smart Export Guarantee. You'll get your MCS certificate and electrical certificates when we hand the system over.
It depends on your roof, how many panels you need and whether you add a battery. See our solar panel prices by system size, or use our online solar designer for an instant quote.
For homes, finance is available through our finance partners, Hometree and Phoenix. All finance subject to status and credit checks. Businesses can choose outright purchase, a Smart Ease payment plan or a Power Purchase Agreement, where you pay for the power the system produces rather than for the system.
Yes. We've completed 300+ commercial installations across 11 UK regions, including manufacturing sites, warehouses, schools and sports clubs. We plan each project around how the site runs, handle the grid application and hand over all the certificates.
We commission the system, deal with the grid (DNO) paperwork and send you your certificates. Solar and battery systems come with an app, so you can see what you're generating and using, and we're here if you need help afterwards.
