Someone cleaned a patch of your driveway? Check this before you agree to the rest
A driveway-cleaning test patch can be a genuine demonstration, but it can also be used to create pressure. Check permission, the total price and what happens next before agreeing.

What should I do now?
Someone is at the door now
•Do not make a rushed decision. You can say you are not agreeing to any work today.
•Ask for the business name, address, telephone number and a written total price.
•Say clearly that no test patch or additional work is authorised unless you have agreed it.
•Take the details away and check them independently; do not rely only on a leaflet or number provided at the door.
•For a sizeable job, compare another quote before deciding.
•If the person becomes threatening, will not stop or refuses to leave, move somewhere safe and call 999.
The work has already happened
•Keep the quote, invoice, leaflet, business card, messages, call details and payment record.
•Photograph the driveway, the test patch, unfinished areas and any damage before anything changes.
•Write down what was originally agreed, who was present, and how the work or price changed.
•Do not make another payment simply because you are being pressured.
•Contact Citizens Advice consumer service for advice about your circumstances and possible Trading Standards referral.

What is the driveway-cleaning test-patch tactic?
A cleaner calls at a home and offers to pressure-wash a small part of the driveway as a demonstration. Sometimes the resident agrees to the demonstration; in more concerning cases, the patch is cleaned before clear permission is given. The brighter patch then sits against the surrounding dirt, making the driveway look uneven and creating a strong reason to finish the rest.
Bromley Trading Standards has specifically warned that rogue traders have used test patches to pressure residents into buying more work and, in one reported incident, demanded money for a patch and other work the resident had not requested. That evidence establishes that the tactic can be misused. It does not mean every cleaner who offers a demonstration is dishonest. The useful test is what happens around it: permission, identification, a clear total, written information, room to decide and no pressure are more reassuring.
Why can a small clean patch feel so persuasive?
Pressure washing can create an immediate and dramatic contrast. Once one patch is bright, leaving the rest untouched may feel like accepting a new blemish. The demonstration also changes the conversation: instead of deciding whether you wanted driveway cleaning, you may feel you are deciding whether to repair an awkward-looking result already created.
That feeling is understandable, but it is not a reason to agree on the spot. A demonstration should help you understand the likely finish, not remove your ability to make a calm choice. A legitimate cleaner can ask permission, explain that results may vary across the surface and leave a written quote for you to consider.
Agree the complete price before work starts
Ask for a total in pounds, not only a day rate or a price per square metre. If a unit price is used, ask the trader to record the measured area and final calculation. The written quote should say whether it covers pressure washing, weed or moss treatment, re-sanding block paving, stain treatment, sealing, moving objects, water use, waste removal and VAT.
A low cleaning price can grow when treatments or repairs are added. Extra work is not automatically unreasonable: a cleaner may uncover oil staining, loose jointing sand or damaged paving that was difficult to see. What matters is that they explain it, price it and obtain your agreement before doing it. You should be free to decline the extra or seek another opinion.
What if work starts without permission?
Say clearly that you have not authorised the work and want it to stop. Do not agree to the full job merely because the surface has already been changed. If it is safe, record what is happening and ask another person to be present. Do not put yourself at risk to collect evidence.
Current CMA guidance gives a home-improvement cold-calling example in which a trader starts work without explicit permission to pressure consumers. It explains that, in the circumstances described, starting work without an express written request can leave the consumer with no liability to pay for that work under the Consumer Contracts Regulations. Your own rights depend on the facts, so get individual advice rather than treating a general example as a final legal decision.
Doorstep agreements and cancellation information
A contract agreed at your home will often be an off-premises or doorstep contract. GOV.UK says traders covered by these rules must provide key information before the order, including the business identity, contact details, description of the service, total price or how it will be calculated, payment arrangements and cancellation information in a form you can keep. A 14-day cancellation right commonly applies, but there are exceptions, including goods or services worth £42 or less, and the position changes if you expressly ask for a service to begin during the cancellation period.
Do not assume that cancelling means every possible cost disappears, or that a trader can ignore cancellation rules because work has begun. Citizens Advice can assess what was agreed, the value, what information was supplied and whether you requested an early start.
If you have already paid or the work is disputed
Preserve evidence before arranging remedial cleaning or repairs. Take wide and close photographs, keep all paperwork and save messages in a form you can retrieve. Write a short timeline including the first price, each additional request, the work carried out and each payment. If workmanship, damage or unnecessary treatment is disputed, consider asking an independent driveway or paving professional for a written assessment.
Contact the trader in writing if it is safe and appropriate, state the problem plainly and keep a copy. Avoid making allegations you cannot support; describe what happened and what outcome you want. Citizens Advice can help you understand possible remedies and can pass relevant information to Trading Standards. If the circumstances may amount to fraud, Report Fraud is the national reporting service for England, Wales and Northern Ireland. If you paid by bank transfer or card, contact the provider promptly and accurately explain the transaction.
How to choose a driveway cleaner more safely next time
Start with the job rather than the sales pitch. Note the surface type, approximate area, stains, access and whether you want re-sanding or sealing. Ask two or three businesses to quote for the same written scope. Compare the total, exclusions and process—not only the headline price.
Check that the business identity on the quote matches the contact details and payment name. Look for a usable address, recent examples of comparable work and clear answers about insurance and surface risks. Membership of a scheme can be relevant information, but check it directly with the scheme and do not treat a badge as a guarantee of workmanship.
A careful cleaner should discuss drainage, nearby doors and walls, loose pointing or damaged paving, and the possibility that stubborn stains will not disappear completely. They should also explain what happens if the condition of the surface requires a change. Clear standards help legitimate local cleaners too: written scope and permission protect both sides from misunderstandings.
