How to judge a renewable energy installer

Independent, no-ads guidance — the trade-specific checks that matter most, the warning signs, and what to ask before you hire. Use it alongside each trader’s public evidence above.

Verify before you hire

  • Check the installer holds a current MCS certificate covering your specific technology — Solar PV and heat pumps are separate MCS scopes, so confirm the right one at mcscertified.com.
  • Confirm membership of RECC or HIES before paying any deposit — these consumer codes provide deposit insurance and a workmanship guarantee that survives if the installer folds.
  • Verify TrustMark registration if you're applying for ECO4 or Warm Homes Plan grants — it's a hard requirement for most government-funded energy schemes.
  • Check Companies House for incorporation date and current filing status — a company under two years old taking a large deposit is a genuine risk in this sector.

Warning signs of a cowboy

  • No current MCS certificate, or one that doesn't cover the technology they're quoting for — you'll lose any government grant if they install without it.
  • Pressure to sign quickly or pay a large deposit before you've seen proof of MCS, RECC/HIES, and insurance documentation.
  • Unsolicited door-knock or cold call promising a free or zero-cost 'government scheme' installation — a common scam tactic in this trade.
  • Vague paperwork or no mention of DNO grid notification (G98/G99) or building regulations sign-off — omitting these blocks Smart Export Guarantee payments and can void your buildings insurance.

Questions to ask before you hire

  • Can you show me your current MCS certificate and confirm it covers the exact technology you're installing?
  • Are you a member of RECC or HIES, and will my deposit be covered by deposit insurance from the day I pay?
  • How do you handle the DNO grid notification and building regulations self-certification — do you take care of that, or do I need to arrange it?
  • How many systems of this type have you installed in the past two years, and can you point me to recent customer reviews that mention how the grant application was handled?

Frequently asked questions

How do I choose a trustworthy renewable energy installer?
Compare the public evidence on each profile — how many independent reviews they have and across how many named platforms, the rating and how recent it is, any verified credentials, and the company record. A renewable energy installer backed by several named sources is harder to fake than one with a single listing.
Does MyTrustedTraders rank or recommend renewable energy installers for payment?
No. There are no ads and no paid placement. Renewable energy installers are ranked only by the strength of independent public evidence — no one can pay to rank higher, add a badge, or change their reviews.
Where do the reviews come from?
They're imported from named public review platforms and always shown with the source named — they aren't reviews written on MyTrustedTraders. We cross-check the same business across sources rather than creating new reviews.
What should I check before hiring a renewable energy installer?
Confirm credentials and insurance directly with the renewable energy installer, get a written quote, and run the Cowboy Checker on the business first. MyTrustedTraders helps you shortlist on the evidence — it doesn't replace your own checks before you hire.
