Renters' Rights Act 2025: three things that changed for end-of-tenancy cleaning in London.

The Renters' Rights Act 2025 reshaped a lot more than the headlines suggested. For London tenants and letting agents, three concrete changes are already affecting how end-of-tenancy cleaning is charged and disputed in 2026.

1. "Professional clean required" only if move-in was professional

Before 2025, many London tenancies had a clause requiring "professional standard" cleaning at move-out, regardless of how the property was handed over at move-in. Under the Act framework now in force, that clause is unenforceable unless the inventory and tenancy agreement document a professional clean at the start of the tenancy.

What this means: if you moved into a flat that was not professionally cleaned, the standard at exit is "return to check-in condition", evidenced by the original inventory — not an arbitrary "professional" benchmark.

2. Flat-fee deductions are routinely overturned

The Tenancy Deposit Scheme (TDS) and the deposit-protection alternatives have, since 2025, increasingly rejected flat-fee cleaning deductions submitted without itemised evidence. A landlord deducting £350 for "professional clean" with no breakdown of hours, areas covered, or rate now usually loses the dispute.

What this means: in 2026, cleaning deductions that hold up in adjudication look like an itemised invoice — hourly rate, hours worked, areas covered, before-and-after photos.

3. Faster mediation for cleaning disputes under £400

The Act expanded the Private Rented Sector ombudsman service. Most cleaning-only disputes (typically £150–£400 in London) now route through ombudsman mediation rather than full TDS adjudication — faster turnaround, often days instead of weeks.

What it means for tenants and agents in 2026

If you're handing back a tenancy in NW1, E8, N1, SW11 or W1, choose a cleaner that produces three things automatically: itemised hourly invoice, before-and-after photos, 72-hour free re-clean window if the inventory clerk flags an issue. Those three turn a 60-day deposit dispute into a 7-day deposit return.
