You have decided your current window cleaner is not working out. Maybe cleans are being missed, communication has gone quiet, or you have lost confidence in their paperwork. Whatever the reason, one worry usually holds facility managers back from making the change: hassle.
The fear is a gap in service, a messy handover, or a new team that does not know your building. In reality, switching commercial window cleaning providers is straightforward when you plan it properly and choose a contractor who manages the transition for you.
This guide walks you through exactly how to switch without disruption, from checking your contract to handing over site access and keeping your building compliant throughout.
Quick Answer
To switch commercial window cleaning providers without disruption, check your current contract’s notice period first, line up your new contractor before you cancel, and plan an overlap so no clean is missed.
Hand over site access, permits and compliance documents (including RAMS and current eyebolt certification) before the first visit, then inspect the first clean to confirm standards.
Key Takeaways
Check your notice period before doing anything else. Most commercial contracts require 30 to 90 days written notice.
Appoint the new contractor before you cancel the old one. This is what prevents a gap in service.
Access and compliance are the real handover. Keys, permits, RAMS and anchor point certification matter more than the paperwork of cancelling.
A good contractor manages the switch for you. The right provider handles scheduling, documentation and access so you barely notice the change.
How do you know it is time to switch?
Most facility managers reach this point for the same handful of reasons. Cleans get missed or turn up late. Emails go unanswered. Safety documentation is vague or out of date. Or the price has crept up while the standard has slipped.
If any of that sounds familiar, you have probably already made your decision. For a fuller rundown of the warning signs, see our guide on the signs you should change your commercial cleaning provider. This article picks up where that one leaves off: the how, not the whether.
Check your current contract first
Before you speak to anyone, read your existing agreement. This one step avoids most switching problems.
Look for four things:
- Notice period. Commercial window cleaning contracts commonly require 30, 60 or 90 days written notice.
- Termination clause. Check how notice must be given and whether there are any early exit conditions.
- Auto-renewal terms. Many contracts roll over automatically unless you cancel within a set window. Miss it and you could be tied in for another year.
- Equipment ownership. Confirm nothing installed on site, such as anchor points or fixings, belongs to the outgoing provider.
Always give notice in writing and keep a dated copy. A verbal or unconfirmed cancellation is the most common cause of disputed billing and delayed switches.
What to look for in your new contractor
Switching only pays off if the new provider is genuinely better. In commercial window cleaning, the things that matter are safety, compliance and reliability, not just price.
Use this as a checklist when comparing contractors.
| What To Check | Why It Matters |
|---|---|
| Directly employed, DBS-checked staff | No subcontractors or last-minute replacements turning up on your site |
| Height qualifications (IRATA, IPAF) | Proof operatives are trained for rope access and powered access work |
| Site-specific RAMS as standard | A Risk Assessment and Method Statement for your building, provided before work starts |
| Insurance with no height restrictions | Full public and employer's liability cover, whatever the building height |
| Recognised accreditations | CHAS, SafeContractor, RoSPA and BICSc show independently verified standards |
At All Clean Services, all of the above come as standard. For more on vetting a contractor properly, read our guide to the questions to ask when hiring a commercial window cleaner and why the hidden risks of cheap window cleaning can cost more in the long run.
Can you switch mid-contract?
Usually yes, but your notice period sets the timeline. If you are inside a fixed term, check the termination clause for any early exit conditions. In many cases you can serve notice so the switch completes as the term ends, avoiding any penalty.
Switching is also a good moment to review whether you are getting the best value across your whole portfolio. If you manage several buildings with different cleaners, consolidating them under one contractor can cut costs and simplify compliance. We cover this in our posts on consolidating your window cleaning contracts and the benefits of contract window cleaning.
Your Switching Checklist
Run through these in order:
- Review your current contract for notice period and renewal terms.
- Shortlist and vet new contractors on safety, compliance and reliability.
- Appoint your chosen provider and agree a start date.
- Give written notice to your current contractor and keep a copy.
- Arrange access: keys, fobs, permits and parking.
- Confirm compliance: RAMS and current anchor point certification.
- Schedule the first clean to overlap with your notice period.
- Inspect the first visit and review closely for the first month.
Frequently Asked Questions (FAQs)
How much notice do I need to give my current window cleaning provider?
Most commercial contracts require 30 to 90 days written notice. Check your termination clause, give notice in writing, and keep a dated copy.
Will there be a gap in cleaning when I switch?
Not if you plan it right. Appoint your new contractor before cancelling the old one, and schedule their first visit to fall within your notice period so no clean is missed.
Can I switch window cleaning providers mid-contract?
Often yes. Your notice period and termination clause determine when. You can usually time the switch to complete as the term ends to avoid penalties.
Does the new contractor need new eyebolt or anchor point testing?
Your anchor points must have current test certification for any team working at height. A good contractor will confirm this before their first visit and arrange testing if needed.
How much does commercial window cleaning cost?
Costs depend on building height, access method, frequency and glass area. See our guide to commercial window cleaning costs for typical ranges.
