Is a doorstep solar panel or cavity wall insulation quote a scam?
Unsolicited doorstep quotes for home improvements often use high-pressure selling, inflated prices, or upfront deposits that disappear. Always get multiple written quotes and check contractor credentials.

Explanation
Doorstep home improvement fraud targets homeowners, particularly older residents, with offers of solar panel installation, cavity wall insulation, driveway resurfacing, or roof repairs — sometimes claiming to be affiliated with a government grant scheme. Tactics include artificially urgent pricing, scare tactics about structural damage, and pressure to sign and pay a large deposit the same day. Once a deposit is paid, work may never begin, be of poor quality, or create more damage than existed.
The scare variant deserves particular caution: a caller 'notices' loose tiles or dangerous wiring from the street, sometimes climbs up uninvited to 'check', and returns with photographs — not necessarily of your roof — showing urgent problems. Fear of leaks or collapse converts into a same-day contract at whatever price is quoted. The grant-scheme variant works the opposite emotion, dangling free or subsidised improvements that require an up-front 'survey fee' or your bank details to 'register eligibility'. Real grant schemes are applied for through official channels, not sold door to door.
Legitimate tradespeople provide written quotes, do not require large upfront payments, are registered with professional bodies, and do not pressure you to decide on the day — a genuine price is still valid next week. Get at least three written quotes for any significant work, check contractors against your national trade register, and pay by card or staged payments where possible. Many countries also give you a legal cooling-off period for contracts signed at home; a trader who denies that right is telling you what they are.
Common red flags
- Salesperson arrives unsolicited and insists the offer is only valid today
- Large deposit required on the day of the quote
- Contractor claims to be carrying out work in your street and has leftover materials
- No written quote, contract, or cooling-off period offered
What to do now
- Take the time to get at least three written quotes from verified tradespeople
- Check contractor registration on your national trade body or consumer protection register
- Never pay more than a small deposit before work begins
- If you already paid and work was not completed, report to trading standards
Frequently asked questions
How do I check if a home improvement company is legitimate?
Search the company name on your national trade body register (such as TrustMark or Which Trusted Traders in the UK), check Companies House or equivalent, and read independent reviews on established platforms.
A caller showed me photos of damage on my roof. Should I let them fix it?
Not on the spot. The photos may not be of your roof at all, and inventing urgent damage is a classic pressure tactic. Get an independent roofer or surveyor to inspect before agreeing to anything.
Do I have a right to cancel a contract signed at my door?
In many countries, contracts signed in your home carry a statutory cooling-off period during which you can cancel in writing. Check your national consumer rules quickly — the window is short — and a trader who denies the right is itself a red flag.
