What to check when hiring solar installers in the United Kingdom

MyTrustedTraders ranks on independent public evidence — no ads, no paid placement. Use these checks alongside the evidence on each profile before you decide who to contact.

  • Look for consistent reviews across several named platforms, not one polished profile.
  • Check any verified credentials, and that the business details independently check out.
  • Get a written quote and keep guarantee, insurance and payment terms in writing.
  • Run the Cowboy Checker before you commit to anyone.

How to judge a solar 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 they hold a current MCS certification — without it you cannot claim any UK government grant (ECO4, Warm Homes Plan) or Smart Export Guarantee payments.
  • Confirm they are a member of RECC or HIES — both are mandatory for MCS installers and give you deposit protection and a workmanship guarantee that survives if the company folds.
  • Look up their Companies House filing history: how long have they been trading, and are their accounts up to date? This sector has high insolvency rates.
  • If you live in a conservation area or listed building, ask for evidence they have handled planning permission for solar in restricted areas before.

Warning signs of a cowboy

  • They cannot show you a current MCS certificate — no MCS means you lose all grant entitlement and the install may be uninsurable.
  • They quote unusually fast savings or promise a "government grant refund" scheme over the phone or on the doorstep — a known fraud pattern flagged by Trading Standards.
  • They ask for a large deposit in cash with no written contract — the RECC/HIES consumer codes exist precisely because deposit losses are common when firms collapse.
  • The company was incorporated recently (check Companies House) and is pushing you to sign quickly — new firms taking big deposits in a high-insolvency sector is a serious risk.

Questions to ask before you hire

  • Can you show me your current MCS certificate and confirm you are registered with RECC or HIES right now?
  • Who is your Insurance-Backed Guarantee provider, and how long does the workmanship warranty run?
  • Will you handle the G98 or G99 notification to my Distribution Network Operator, and when will that be done before you switch the system on?
  • How many solar installations have you completed locally, and can you point me to some in my area on the MCS Installation Database?

Frequently asked questions

How do I choose a trustworthy solar 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 solar installer backed by several named sources is harder to fake than one with a single listing.
Does MyTrustedTraders rank or recommend solar installers for payment?
No. There are no ads and no paid placement. Solar 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 solar installer?
Confirm credentials and insurance directly with the solar 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.
