Claim This ListingOneEnergy runs out of Birmingham as a local solar installer covering West Midlands and the surrounding area.
OneEnergy runs their public-facing website at oneenergy.org.uk — useful for cross-checking current services and recent project photos before booking.
OneEnergy’s Google review presence is limited. New firms are common in solar — the question is whether they’ll show you proper recent work samples.
Before signing a contract with OneEnergy, check three independent registers: the MCS Certified register for installer status, RECC or HIES for consumer protection cover, and Companies House for company status and recent accounts. EnergyRanked does not verify these credentials on your behalf — we surface third-party signals and link you to the registers where you can verify yourself.

Frequently asked questions
Does OneEnergy offer Insurance Backed Guarantees (IBG)?
An IBG is essential — it covers the workmanship warranty if the installer ceases trading. MCS-certified installers usually offer IBG via the MCS scheme. Confirm OneEnergy provides an IBG certificate at handover; don't accept a workmanship guarantee that's only as good as the installer's continued existence.
Is OneEnergy MCS Certified for solar PV?
MCS certification is the industry standard for UK solar installers. Check the live MCS register at mcscertified.com — search by company name. If OneEnergy is currently MCS Certified, their name and certificate number will appear. If not listed, ask why.
Does OneEnergy handle Smart Export Guarantee (SEG) registration?
SEG registration is usually handled by your electricity supplier rather than your installer, but OneEnergy should provide the MCS certificate and inverter performance data your supplier will request. Ask OneEnergy whether they walk customers through the SEG paperwork as part of handover.
How do I verify OneEnergy on Companies House?
Search 'find-and-update.company-information.service.gov.uk' for the trading name. Look at incorporation date, current status (Active vs Liquidation/Dissolved), most recent accounts filing, and director list. A long-trading limited company with up-to-date accounts is a safer signal than a recently incorporated firm.
How many Google reviews does OneEnergy have?
Review volume is limited at present. Ask OneEnergy for two or three customer references from their last 6 months of work; reputable installers will provide them. A small review count isn't disqualifying for a newer firm, but you should expect to see recent project photos.
