When considering who to choose as your high-rise window cleaning firm for your residential block, hotel, shopping centre, venue or office building, there are a number of things to consider. Firstly, and most obviously, there’s the question of quality – are they going to do a good job? But more importantly than that, are they going to be safe, could people get hurt if they’re negligent, and would you be liable if they did? A little on the negative side, but it is something to consider and helps to sharpen the mind on finding the best window cleaning firm for your needs.

We’ve put together our top six tips for identifying a quality high-rise window cleaner for you, but if you have any more to add do let us know:


Health and Safety and IRATA training (for rope access and abseiling) are the most important for a high-rise window cleaning firm to evidence that they have up-to-date certification for. But staff may also need MEWP (mobile elevating work platform) and IPAF (International Powered Access Federation) training for the safe use of all access equipment needed at your site.

Memberships and associations

Some industry associations are ‘pay-and-play’ – pay your money and you can join for the perceived credibility it offers, while others require members to comply to a code of conduct. Check out what the associations your high-rise window cleaner is a member of to see what that says about them.


Your high-rise window cleaner should have the two main insurances covered – public liability insurance (covering damage and injury caused by an accident), and employers’ liability insurance (should any of their workforce become ill or injured). If the window cleaners you’re considering are not fully covered, then they may well not be the right firm for you after all.


How long has your prospective window cleaning firm been in business for? We have come across some exceptional new guys, dedicated to a job well done, invested in the latest equipment and committed to their health and safety, but just like in any industry, age can sometimes be a good measure of quality. Any business that has been around for long enough to build up a digital footprint will give you the opportunity to seek out unfiltered evidence online of what clients really think about them. A number of years should be enough for those who have been unhappy with a service, or who have had poor experiences of the firm to be able to write about them on social media, in blogs, in legal documents, and so on. Do your digital research.

Client References

If the high-rise window cleaning firm you’re considering is at all reluctant in offering up references on request then this may be a red flag moment. Those that have been around for a while will realise that references are a vital part of evidencing that they’re a trustworthy organisation. They may even offer up testimonials without being asked and allow you to speak with a few of them so you can validate their worth.

Environmental credentials

Whether or not your company has an official environmental policy it makes sense to include supplier commitment to eco-friendly strategies for servicing your needs into your decision-making process. Window cleaners use a large volume of water and chemicals, but some take their environmental credentials seriously. You’ll want to consider them most carefully.

London Window Cleaners takes all of the above very seriously. All our staff maintain their training certification and our equipment is certified as safe every six months. We’re members of the Federation of Window Cleaners (FWC), our staff are IPAF, IRATA and CSCS (Construction Skills Certification Scheme) trained, and we’re CHAS and SafeContractor accredited. Our site manager conducts regular safety audits to ensure we are compliant with current practices and quality standards. We’re fully insured, offer a 48-hour guarantee on all our work that states if you’re not completely satisfied we’ll pop back and clean any windows you’re not happy with. And we are committed to running an eco-responsible business, using rainwater (where possible), which we purify ourselves for a cleaner window outcome without any chemicals, all brought to you in our all-electric vehicle.
