Founded in Whitehaven in 2013 as an electrical contractor, Thomson Energy Solutions installs and maintains solar panels, battery storage and EV chargers for homes and businesses across Cumbria, alongside domestic and commercial electrical work. The company says it began with off-grid solar systems in 2020 before taking on grid-connected installations, and that its team of eight has completed more than 200 installations. It is MCS certified for solar PV and battery storage (MCS certificate SICI-22673, checked on the MCS installer search on 25 September 2026).

The company says it surveys each property and designs the system before quoting, handles planning approvals and the DNO grid-connection application, and commissions the system and sets up monitoring after installation. It also offers maintenance and inspections for solar panels and batteries.

It works with AIKO, REC, JA Solar and JinkoSolar panels and with Tesla Powerwall, GivEnergy, Fox ESS and Sigenergy batteries, and its project listings name DMEGC panels and EcoFlow inverters and batteries. Recent projects include a 4 kW system with a battery on a home in Egremont and a 10.3 kW system with a battery on a home in Whitehaven.
