The most common compliance gaps

Most self-managing landlords have at least one of these.

They’re rarely obvious. That’s what makes them expensive.

Deposit paperwork served incorrectly
Protecting the deposit isn’t enough. The prescribed information must be correctly served within 30 days. Most landlords who get this wrong didn’t know there were two separate steps.
No ICO registration as a data controller
Every landlord who holds tenant data is a data controller under UK GDPR. Most aren’t registered with the ICO. The annual fee is £40–60. The fine for non-compliance is not.
Tenancy agreement not updated for 2025
The Renters’ Rights Act abolished Assured Shorthold Tenancies from May 2026. If your agreement still references Section 21 or a fixed term creating a new tenancy, it needs replacing.
Rent increases served without a Form 4A
Under an Assured Periodic Tenancy, rent can only be increased once a year and must be served using the prescribed Form 4A with two months’ notice. An informal letter is not valid.
No PRS Ombudsman registration
From 2025, all private landlords must join a government-approved redress scheme — not just letting agents. Most self-managing landlords don’t know this applies to them directly.
Making Tax Digital not on the radar
MTD for Income Tax is mandatory from April 2026 for landlords with qualifying income above £50,000 — dropping to £30,000 in 2027. Quarterly digital submissions to HMRC. Paper records won’t be accepted.
