Solar Panel Installation Scams

The UK is adopting renewable energy at a great pace and with this, solar panels are becoming a popular choice for homeowners aiming to reduce their carbon footprint and their energy costs. However, with the increased demand for solar panel installations, there is a rise in unethical installers and unsafe and badly executed installations. Unfortunately, it is more common than you would think for the wrong solar panel installers to be chosen for these jobs, resulting in customers losing their hard-earned cash, and having to deal with safety hazards and long-term issues with their solar systems. This blog post aims to provide you with enough information on how to defend yourself against such scams.

Solar Panel Fires on the Rise

There has been increased reporting of fires involving PV systems as deployment has grown. Press analyses cited around 66 incidents up to mid‑2023 in England. With many more systems now installed, absolute incident numbers have risen, but when systems are designed, installed and maintained to standards (BS 7671; MCS‑certified products/installation), PV remains a very safe technology. This underlines the importance of using competent, accredited installers and certified products.

Common Scams Related to Solar in the UK

1. Products and services being misrepresented: Some questionable companies bait‑and‑switch to lower‑quality panels/inverters than quoted, risking reduced output and voided warranties.
2. Hard‑Sell Tactics: Pressure to sign “today only” or “limited time” deals. Reputable businesses give you time to make an informed decision.
3. Fake solar companies: Hefty deposits taken and then no work delivered. Some falsely imply links to government/MCS/RECC or promote fake schemes.
4. “Warranty expiry” cold calls/texts: Scammers impersonating “MCS” or “the manufacturer” to sell “warranty renewals.” MCS does not cold‑call or sell warranties.

Red Flags to Look Out For

• Unsolicited Offers: Be wary of phone calls, emails, or door‑to‑door approaches offering “free health checks,” “upgrades,” or special deals, especially if they claim government backing.
• Lack of Transparency: Vague pricing, evasiveness about products, or refusal to answer technical questions.
• Poor Presence Online: No credible website, few verifiable reviews, newly created profiles, or no trading history.

Risks of Poor Installation

• Electrical Hazards: Faulty wiring, incorrect DC connectors, or improper protection can lead to failures or, rarely, fires.
• Roof Damage: Poor mounting can cause leaks and structural issues.
• Underperforming Systems: Shading/design errors, wrong components, or poor commissioning reduce output and ROI.
• Voided Warranties: Using unaccredited installers or non‑compliant equipment can void manufacturer warranties and prevent access to SEG export with most suppliers.

How to Protect Yourself

1. Do Thorough Research: Check multiple companies. Look for verified reviews, trading history (e.g., Companies House), and examples of work.
2. Verify Accreditations: In Scotland/GB, choose an MCS‑certified installer and products, and look for RECC membership for consumer protections (HIES or similar schemes are also reputable). Most SEG export tariffs require MCS certification (or equivalent), and suppliers typically insist on MCS.
3. Consider HIES Insurance: HIES offers consumer protection including insurance‑backed guarantees. Using a member can provide added peace of mind.
4. Get Multiple Quotes: Ask for itemised, like‑for‑like proposals (panel and inverter models, mounting, scaffolding, monitoring, DNO application, MCS handover, warranties).
5. Read Contracts Carefully: Check payment schedules, scope, commissioning, DNO/MCS responsibilities, and exclusions. Don’t sign on the spot.
6. Avoid Large Upfront Payments: A reasonable deposit is normal; avoid disproportionate prepayments. Use secure payment methods.

Scotland‑specific notes to stay safe (2025)

• Planning rules: Most roof‑mounted domestic solar in Scotland is permitted development under updated rules (2024), but listed buildings and some conservation‑area elevations still need consent; World Heritage Sites are excluded. Check with your council if unsure.
• DNO approval: In Scotland, SP Energy Networks and SSEN are the DNOs. Up to 3.68 kW export per phase typically follows G98 (install then notify). Higher export or certain configurations need prior G99 approval, which can add 2–4+ weeks. Avoid installers who skip proper DNO processes.
• SEG export: The Smart Export Guarantee applies across Great Britain (England, Scotland, Wales). You’ll need MCS certification (or equivalent acceptable to the licensee), an export‑capable smart meter, and an export MPAN. Be wary of anyone promising fixed export rates “for years” without pointing you to current supplier tariffs.

Conclusion

Investing in solar panels is a significant commitment that offers numerous long-term benefits when done correctly. However, the risks associated with choosing an unreliable installer are substantial. By staying vigilant, conducting thorough research, and being aware of the warning signs, you can protect yourself from scams and ensure your solar investment is safe and effective. If an offer seems too good to be true, it probably is. Make informed choices to enjoy the full advantages of solar energy without unnecessary risks.
