A reliable window cleaner should be easy to identify, clear about what the price includes and straightforward to contact. Check that the business genuinely covers your postcode, compare the service rather than price alone, ask how access and bad weather are handled, and keep a written record of any important quote or agreement.
A practical checklist for choosing a reliable window cleaner
Window cleaning is usually a simple service, but it still involves somebody working around your home, garden, vehicles and glazing. A few checks before the first visit can prevent most misunderstandings.
What should a window-cleaning quote include?
For a regular exterior clean, a short written message can be enough — but it should still be clear. Citizens Advice recommends getting written quotes for home services where possible because a written record makes it easier to compare what has been agreed.
A useful window-cleaning quote or confirmation should identify the property, the price, the frequency and the main scope of work. If there is a first-clean surcharge, internal glass, a conservatory roof, gutter clearing or another extra, it should be shown separately.
Insurance and safety: what should you ask?
It is reasonable to ask a business what insurance it carries for the work it performs. Public liability insurance is commonly used to cover claims involving injury to a member of the public or accidental property damage, but it is not the same as employers’ liability insurance.
If a business employs staff, employers’ liability insurance is generally compulsory in Great Britain, subject to statutory exemptions. GOV.UK says employers normally need at least £5 million of cover. That does not mean every self-employed sole trader must have employers’ liability cover.
For work at height, HSE guidance requires businesses to plan the work and choose suitable equipment. HSE specifically gives telescopic water-fed poles as an example of avoiding work at height where reasonably practicable.
How much should you trust online reviews?
Reviews are useful because they can show recurring patterns: whether a cleaner turns up, communicates well, resolves issues and provides consistent results. But a star rating is not proof on its own. Look at the recency of reviews, how many there are, whether comments describe the service you actually need and whether the business details match across platforms.
Be cautious about businesses that make claims that cannot be checked, refuse to explain what the price includes or pressure you into unexpected work. Citizens Advice recommends checking that traders are genuine, getting contact details and being wary when important details will not be put in writing.
Clear and consistent
Real contact details, sensible questions about your property, a clear service area, transparent pricing, recent feedback and straightforward answers about access, payment and weather.
Vague or pressurised
Unclear identity, changing prices without explanation, claims that cannot be verified, pressure for unnecessary extras or refusal to describe what the agreed clean includes.
Choosing a cleaner for a regular round
Reliability matters differently on a recurring service than on a one-off job. A cleaner who visits every few weeks needs a system for reminders, access and payment that works for both sides. Ask what happens when you are away, when a gate is locked, when a vehicle blocks access or when weather forces the round to move.
Also ask whether the price quoted is for the first clean or the ongoing maintenance price. The first visit can take longer because frames, sills and glass may have built-up dirt. For a broader sense of current costs, see our UK window-cleaning price guide.
What if the service is not carried out properly?
Consumer law applies to paid services. Citizens Advice explains that traders should perform services with reasonable care and skill. If something goes wrong, keep messages, receipts and photographs, contact the business promptly and give it a fair opportunity to address the problem.
Most everyday issues are easier to resolve when the original agreement was clear. That is another reason to keep the quote, text message or email that states the price and what was included.
Questions to ask before the first visit
Seven useful questions
- Do you cover my postcode on a regular round?
- Are frames, sills and doors included?
- Is this the first-clean price or the ongoing price?
- How do you clean upper or difficult windows?
- What access do you need to the back of the property?
- What is your bad-weather policy?
