Solar Installer Red Flags in Scotland: How to Spot a Rogue Trader Before You Sign
Not every solar company operating in Scotland is legitimate. Trading Standards Scotland receives hundreds of solar-related complaints each year. Before you commit to any installer, know the eight warning signs that should make you walk away — and how to protect your money if things go wrong.
Why Rogue Solar Traders Operate in Scotland
Solar panels are a large purchase — typically £6,000–£10,000 — and most homeowners make the decision once in a lifetime. That information asymmetry creates a fertile environment for unscrupulous traders. Understanding how they operate is your first line of defence.
Verify First
Check MCS at mcscertified.com and RECC at recc.org.uk before a salesperson even completes their pitch. Both databases are free and public.
Never Sign Same Day
RECC's Code of Practice gives you a 14-day cooling-off period. Any installer who needs you to sign immediately to honour a price is breaching that code.
Pay Smart
Always pay by credit card where possible. Section 75 of the Consumer Credit Act protects purchases over £100 when things go wrong — bank transfer offers no such protection.
8 Red Flags to Watch for When Choosing a Solar Installer
Flags 1–3 are critical — any one of them is sufficient reason to walk away immediately. Flags 4–6 are serious. Flags 7–8 warrant a serious conversation before proceeding.
No MCS Certification
They cannot prove MCS-certified status
MCS (Microgeneration Certification Scheme) certification is not optional — it is a legal requirement to access government incentives like the Smart Export Guarantee, and it is a condition of most Scottish home insurance policies. If an installer cannot immediately provide their MCS certificate number and you cannot verify it at mcscertified.com, stop the conversation. Unverified installers have no accountability, no insurance, and no obligation to honour warranties.
What to do: Go to mcscertified.com, search by company name. If they don't appear, do not proceed.
High-Pressure Same-Day Signing
You are told the offer expires today or this week
Legitimate solar companies do not have genuine 'today only' pricing or 'last available install slot' tactics. These are pressure-selling techniques banned under RECC's Code of Practice. If a salesperson tells you prices are going up tomorrow, or that your neighbour already signed, or that a government scheme closes at midnight, you are being manipulated. Real price variations are transparent and do not require you to sign immediately.
What to do: Tell them you'll call back in 3 days. If they withdraw the offer, that confirms it was a manipulation tactic.
Claiming Government Grants That Don't Exist
Promises of 'free government grants' for solar in Scotland
There are no direct cash grants for solar panels available to most homeowners in Scotland in 2026. Home Energy Scotland offers interest-free loans, not grants. The Smart Export Guarantee is a tariff, not a grant. The Feed-in Tariff closed in 2019. Any salesperson who tells you that 'the government is paying for most of this' or that you qualify for a special grant is either misinformed or deliberately misleading you.
What to do: Check homeenergyscotland.org for current, accurate funding options. Don't sign anything based on a grant claim.
No Itemised Written Quote
Quote is verbal only or lists only a total price
A credible solar quote must specify: panel brand, model, and wattage; inverter brand, model, and warranty; total kWp capacity; roof survey findings; scaffolding and labour costs; DNO application process; expected annual generation; projected payback period; and all warranty terms. A single total price scrawled on a piece of paper is not a quote — it is a verbal agreement with nothing to protect you when problems arise.
What to do: Request a written itemised quote. If they refuse or stall, get a quote from a RECC-registered installer instead.
Unbranded or Vague Panel Specifications
They won't tell you exactly which panels you're getting
Every solar panel installation in Scotland should use panels with a clearly identified manufacturer, model number, and efficiency rating. 'Tier 1 panels' or 'premium Chinese panels' are not specifications — they are sales language. If an installer cannot or will not tell you the exact make and model of the panels they plan to fit, it likely means they will substitute cheap, low-warranty panels on install day that differ from what was discussed.
What to do: Ask for the exact make, model, and product datasheet for panels and inverter before signing anything.
Large Upfront Payment Required
Requesting 50%+ payment before any work begins
Standard industry practice is a deposit of 10–25% to cover initial material orders, with the balance due upon satisfactory completion. Some legitimate companies ask for a second stage payment once panels arrive, but still hold back the final 10–15% until sign-off. Demanding 75% or the full cost upfront is a cash-grab pattern seen repeatedly in Trading Standards Scotland cases. It removes your leverage entirely if the work is poor or the company disappears.
What to do: Agree only to a maximum 25% deposit. Pay by credit card for Section 75 Consumer Credit Act protection.
No Roof Survey Before Pricing
Price given without anyone assessing your roof
Solar panel pricing depends on roof type, pitch, orientation, shading from trees or chimneys, structural suitability, and existing electrical system capacity. Quoting a fixed price from satellite images or during a single visit without a proper structural assessment is irresponsible. It also means the quote is likely to 'change' significantly once the crew arrives on install day, leading to pressure to pay more mid-job.
What to do: Insist on a full in-person roof survey before any pricing is confirmed. A legitimate installer will expect to do this.
No Clear Complaints or Warranty Process
They can't tell you what happens if something goes wrong
Ask directly: 'If there's a problem with my panels in year 3, who do I call?' A legitimate installer will explain their in-house defect process, their manufacturer warranty escalation route, and their RECC-backed dispute resolution option. If the answer is vague, or if the salesperson defers with 'we'll sort it out don't worry,' that is a significant concern. After-sales support disappears entirely with rogue traders once payment clears.
What to do: Ask for the complaints process and warranty claim procedure in writing before you sign. If they can't provide it, walk away.
4 Real Scam Patterns Reported in Scotland
These are the recurring patterns documented by Trading Standards Scotland and Citizens Advice. Knowing them makes them far easier to recognise in practice.
The Government Grant Door Knock
A caller arrives unannounced claiming your area has been 'selected' for a government energy efficiency scheme and you can have solar panels at no cost or heavily subsidised. They may carry official-looking paperwork and reference real schemes (like Home Energy Scotland) to add credibility.
How to spot it
Real government schemes never use cold-calling door-knockers. Home Energy Scotland operates through a phone helpline (0808 808 2282) and never sends agents to your door uninvited.
Typical outcome
Victim pays a deposit, panels are never installed or are cheap unbranded units with no warranty.
The End-of-Scheme Urgency Close
A salesperson tells you that a government subsidy, feed-in tariff, or manufacturer rebate closes at the end of this month. You're told that acting now means you'll pay far less than neighbours who wait. Multiple phone calls follow in the days after the initial visit.
How to spot it
Real government policy changes are publicly announced weeks or months in advance and apply to all qualifying customers uniformly. No legitimate installer has special early access to closing a subsidy.
Typical outcome
Victim signs immediately under pressure, paying above-market rates for a system that would have cost the same six months later — or the 'savings' never materialise.
The Subcontractor Disappearing Act
A large company sells you a system, takes your deposit, then subcontracts the install to a smaller team. When defects appear, the lead company has dissolved or changed name, and the subcontractor denies responsibility for anything beyond their labour.
How to spot it
Ask before signing: 'Will you be doing the installation directly, or will it be subcontracted?' Insist all warranty obligations are from the company whose name is on the contract, not the subcontractor.
Typical outcome
Homeowner is left with a defective installation and no clear route to redress as two companies point at each other.
The Cheap Solar Substitution
Quote specifies Tier 1 panels (JA Solar, LONGi, etc.) with a 25-year performance warranty. On install day a different crew arrives with unknown-brand panels. When challenged, they claim 'there was a supply issue' and the replacement 'is equivalent or better.' Documentation is vague and no revised contract is offered.
How to spot it
Before install day, obtain the serial numbers of the panels specified in your quote. On install day, check the panels physically match the make and model on your contract. If they don't match, stop the job.
Typical outcome
Homeowner ends up with panels carrying no manufacturer warranty, poor long-term performance, and no recourse to manufacturer if the installer later folds.

What to Do If You've Already Been Scammed or Let Down
Act quickly. The steps below are ordered by urgency. Do not assume the situation is unrecoverable — there are legal routes and consumer protections that can help.
Stop All Further Payments
Do ImmediatelyDo not pay any remaining balance. Do not be pressured into paying a 'completion fee' for work that has not been completed to standard. Any legitimate escalation route requires you to retain leverage — paying in full removes it.
Contact Your Bank
Do ImmediatelyIf you paid by credit card, call your card provider and raise a Section 75 Consumer Credit Act dispute. If you paid by debit card, request a Chargeback. Do this as soon as possible — there are time limits. If you paid by bank transfer, contact your bank's fraud team immediately.
Document Everything
Do Within 48 HoursPhotograph all installed or partially installed work. Save all emails, text messages, contracts, and receipts. Note the names of everyone you spoke to, the dates, and what was said. This documentation is essential for any legal or regulatory complaint.
Report to Trading Standards Scotland

If you believe money was taken with deliberate fraudulent intent, report to Action Fraud at 0300 123 2040 or actionfraud.police.uk. They pass cases to the National Fraud Intelligence Bureau. Keep your Action Fraud reference number safe.
Contact Citizens Advice Scotland
