From False Promises to Hidden Fees: Your Complete Guide to Solar Panel Scams in the UK

At Solar Upgrades, we’ve spoken with many homeowners recently who are understandably cautious when it comes to solar energy. The solar industry has grown rapidly in the UK, which is fantastic for clean energy and lower bills — but that rapid growth has also attracted a wave of misleading companies and scams.

Many customers we speak to have been misled, left with poorly performing systems, or simply no longer trust the companies they initially dealt with. And as we head into the busy Black Friday and winter sales season, it’s especially important to stay alert — this time of year is often when scammers ramp up their offers, hoping to catch people looking for a “too-good-to-miss” deal.

Our goal is simple: to help you make confident, informed decisions about solar energy and avoid falling victim to common scams.

Common Solar Scams to Watch Out For

1. “Free Solar Panels” or “Government-Backed” Offers

Ads promising free solar panels or claiming that you can get a government-funded installation are rarely what they seem. While there are genuine incentives to reduce the cost of solar, there is no completely free system.

Many of these offers involve long-term leases where the company retains ownership of the panels, leaving you with limited benefits and ongoing payments. Always read the fine print and verify who you’re dealing with. Our warm home grant vs solar guide compares grant-funded installations with privately designed systems.

If something seems too cheap — or too expensive — investigate why.

2. High-Pressure Sales Tactics

Scammers often create a sense of urgency by insisting a special discount or “government grant” ends today. This is especially common during winter promotions and Black Friday sales.

Legitimate solar companies give you the time and space to make an informed decision — without pressure or scare tactics.

3. Impersonation of Government or Utility Representatives

Some fraudsters pose as representatives from the government or your utility provider and may use official-looking logos or documentation to appear legitimate. If you receive an unannounced visit or call, always verify their identity and never share personal or financial details until you’re sure they are genuine.

4. Misleading Contracts and Hidden Fees

We’ve seen many cases where homeowners believed they were purchasing a system outright, only to realise later they had signed a long-term lease or finance agreement with escalating payments.

Before signing anything, check the ownership terms, contract length, cancellation process, and any hidden fees. When in doubt, ask a trusted professional to review the agreement.

5. Fake Solar Companies and Identity Theft

Some scammers create fake solar brands or online surveys to collect sensitive information such as bank details or national insurance numbers.

Always ensure the company is MCS-accredited and check independent reviews before sharing personal information or paying deposits.

6. False Promises About Rebates or Tax Credits

Beware of anyone offering instant rebates or cash incentives for going solar. Genuine VAT reductions and government incentives do exist — but they are processed through official channels, not through immediate payments from installers.

7. Unnecessary or Overpriced Upgrades

Owners of older solar systems are often targeted by companies claiming their system needs urgent upgrades. But for those with Feed-in Tariff (FiT) systems, upgrading or altering your installation can void your FiT agreement — resulting in significant financial loss. Reputable companies will always check your FiT status and explain any associated risks before recommending changes.

How to Check a Company’s Certification and Accreditation

Before proceeding with any installation or upgrade, take a few minutes to verify that the company is properly accredited:

These certifications help you separate reputable installers from the growing number of unverified operators. When you’re comparing quotes for solar panel installation for your home, ask every installer for these details, including us.
