Solar Panel Consumer Rights: What Protects You in 2026

If you’re wondering what consumer rights actually protect you when you’re spending £7,000 to £10,000 on a solar system, what to do if the install goes sideways, or how to spot a dodgy outfit before you’ve signed anything, you’re in the right place. The protection landscape genuinely changed in January 2026, the rules around installer accountability are stronger than they’ve ever been, and if you know how to use them you’ll save yourself a lot of heartache (and possibly a lot of money).

01The four pillars of your protection

Consumer rights for a solar installation aren’t a single law or scheme. They’re a stack of overlapping protections, each covering a different risk. Once you can see them as a system rather than a confusing alphabet soup, the rest of this guide makes much more sense.

The first thing to understand is that no single pillar covers everything. The Consumer Rights Act gives you a legal floor but doesn’t help you find a good installer. MCS certifies the installer but doesn’t directly resolve sales disputes. Section 75 protects your money but doesn’t make a faulty install go away. The protection works because the pillars overlap. Skipping one (typically by paying cash, going outside MCS, or using a non-RECC installer) creates a hole that is genuinely difficult to plug after the fact.

02Before you sign: your rights at the quote and sales stage

The most important consumer rights kick in long before any panel goes on a roof. Reputable installers know this and operate accordingly. Cowboy outfits depend on customers not knowing it. Here’s what you’re entitled to.

If you’re at the quote stage now, our solar panel quote checker walks through what a complete quote should look like, line by line, and our breakdown of how much solar panels actually cost gives you the benchmarks to spot quotes that are wildly out either way.

03The deposit and the contract: what’s protected

The deposit is where a lot of consumer harm has historically happened in this industry. A few simple rules cover almost all the risk.

Maximum 25% deposit. RECC contracts cap the deposit at 25% of the total contract price. If an installer asks for 50% or 100% upfront, that alone is a red flag worth walking away from. There’s no good reason for a reputable installer to need more than 25% to cover materials and slot allocation.

The deposit must be protected. Under RECC rules, deposits must be covered by an Insurance-Backed Guarantee or a similar protection mechanism. This means if the installer goes into administration before completing the work, the IBG provider refunds your deposit. Without an IBG you’re an unsecured creditor in the bust, which historically has meant pennies in the pound at best.

Staged payments are normal. A typical structure is 25% on contract, 65% on installation completion (panels up, system commissioned), and 10% retained until MCS certification arrives (which must be issued within 10 working days of commissioning). This protects you from paying in full for work that hasn’t been signed off properly.

04What your contract must actually say

A compliant solar contract isn’t just a price and a signature. RECC and the Consumer Rights Act between them require specific information. If any of the following is missing, push back before you sign.

05When things go wrong: the escalation ladder

Most installations go fine. When they don’t, the order in which you escalate matters – both because it’s what reputable installers expect, and because skipping steps can sometimes weaken your claim. Here’s the sequence.

The big news for 2026 is that step 3 changed. RECC stopped accepting new complaints through its own dispute resolution process on 20 January 2026, transferring that role to Green Homes Dispute Resolution (GHDR). RECC still exists as the consumer code, and your installer is still bound by its rules, but the formal dispute body has changed. GHDR is free to consumers, independent, and approved by the Chartered Trading Standards Institute. Their decisions are binding on member installers.

For free, impartial guidance at any stage of the process – including before you’ve even decided whether you have a complaint – you can call the Citizens Advice consumer helpline on 0808 223 1133 or use the online tools at citizensadvice.org.uk. They also act as the front door to Trading Standards, who can take action against persistent rogue traders.

06The financial backstops if your installer goes bust

The solar industry has had its share of high-profile collapses over the years – several big-name installers have entered administration leaving customers stranded mid-project or with worthless warranties. Three protections exist specifically for that scenario.

Insurance-Backed Guarantee. An IBG is a separate insurance policy taken out at point of installation, paid for by the installer, that covers your deposit and your workmanship warranty if the installer ceases trading. It usually runs for the same period as the workmanship warranty (commonly 10 years). When you receive your contract, the IBG provider’s name and policy details should be included. If they aren’t, ask. If the installer can’t produce them, that’s a serious red flag.

Section 75. If you paid any part of the contract on a credit card (between £100 and £30,000), the card provider is jointly liable for any breach of contract by the installer. This means if the installer disappears or refuses to remedy a serious fault, you can claim against your credit card company directly. The card provider typically has 8 weeks to investigate and respond. This is the strongest protection most consumers have, and it works even if the installer is genuinely bankrupt.

Chargeback. If you paid by debit card, you have a slightly weaker (and shorter) version of the same idea called chargeback. It’s not statutory like Section 75 – it’s a voluntary scheme run by the card networks – but it works for many cases of non-delivery or substantial breach. Time limits are typically 120 days from the date you expected the goods or services.

07Red flags from years of watching solar quotes

Most reputable installers behave decently because their business depends on good reviews and word of mouth. The bad ones exhibit a fairly consistent set of behaviours. Watching dozens of quotes go through over the years, the patterns are unmistakable.

The “today only” tactic is the single most reliable indicator of a problem firm. Solar systems are 25-year decisions. No reputable company believes you should make that call in the time it takes to drink a cup of coffee. Anyone telling you otherwise is either incompetent or deliberately leveraging time pressure to bypass your decision-making. The MCS register is searchable online by postcode and lists every certified installer with their current status. If a name doesn’t appear, you have your answer.

If the system in question is being added to a property you’re considering buying (rather than one you already own), there are extra wrinkles.
