Your London deposit is probably somewhere between £1,500 and £3,500. Possibly a lot more if you're in Zone 1-2. Losing a chunk of that to a cleaning dispute isn't just annoying — it's preventable, and the fix is straightforward once you know what agents are actually checking. The Tenancy Deposit Scheme consistently reports cleaning as the #1 cause of deposit disputes in England and Wales. This guide covers exactly what agents look for, the evidence that protects you, and why a professional clean is almost always the better financial decision. For a detailed room-by-room task list, see our end of tenancy cleaning checklist for London renters.
Why Cleaning Is the #1 Deposit Dispute
The Tenancy Deposit Scheme reports that cleaning accounts for 56% of all deposit deductions across England and Wales. In London, where average deposits run £2,000–£4,000 or more, even a partial deduction is significant. The reason cleaning causes so many disputes is the difference between "clean enough to live in" and "clean enough to relet immediately" — the standard a landlord or agent applies. You could spend a full day cleaning and still fall short of check-in condition if you miss key areas.
What Agents Actually Check
A check-out inspection uses the check-in inventory as a baseline. Agents look specifically at:
- Oven and extractor fan — almost always flagged if not professionally cleaned
- Bathroom grout, sealant, and shower screen limescale
- Inside all kitchen cupboards and drawers
- Carpets — condition compared to check-in
- Walls — marks, scuffs, and hand prints at door heights
- Window frames and sills inside
- Skirting boards throughout
- Behind and under furniture (if you're taking it)
The Professional Invoice Advantage
When you book a professional end of tenancy clean, you receive a dated invoice confirming that a professional service was carried out. Most letting agents accept this as satisfying the cleaning clause in your tenancy agreement, which removes their ability to charge you for cleaning from your deposit — even if they have minor quibbles with the result. This is why professional cleaning at £108–£162 for a typical London flat is almost always the better financial decision versus a deposit deduction at full agency rates (often £200–£400 or more). Under UK tenancy deposit protection rules, landlords must justify any deduction — a professional invoice makes this considerably harder.
Timeline: When to Book
Book your professional end of tenancy clean for the day before or morning of your check-out. You want the property cleaned last — after all your belongings have left. Don't clean and then move furniture out afterwards, as this creates marks and debris you can't address. Leave enough time between the clean finishing and your check-out inspection for any quick touch-ups if needed.
