In this article, we’re revealing the five most common — and costly — errors tenants make when it comes to their tenancy deposit scheme UK.
The good news? Every mistake has a fix. And by the end, you’ll know how to avoid falling into these traps — and how tenancy solicitors like Cook Legal can help if you already have.
Mistake 1: Not Checking If the Deposit Was Protected
This is the most common (and most damaging) oversight.
Landlords in England and Wales are legally required to protect your deposit within 30 days using one of the three official tenancy deposit schemes:
- Tenancy Deposit Scheme (TDS)
- MyDeposits
- Deposit Protection Service (DPS)
Why it matters: If your deposit wasn’t protected on time — or at all — you could be eligible to claim up to 3x the amount in compensation.
How to fix it: Use the GOV.UK checker to see if your deposit is protected. It takes less than 5 minutes.
Mistake 2: Not Asking for the Prescribed Information
Even if the deposit was protected, the landlord must provide you with written confirmation (called “Prescribed Information”). This document outlines:
- Which scheme is holding your deposit
- The terms of the protection
- Your rights as a tenant
Why it matters: If they didn’t send this, they’re still in breach of the law — and you may have a claim.
How to fix it: Ask your landlord or letting agent in writing. If they don’t respond within a reasonable time, speak to a tenancy lawyer.
Mistake 3: Failing to Keep Written Evidence
Verbal agreements don’t hold up well when disputes arise. If you don’t have clear records, proving your case becomes harder.
Why it matters: Without evidence of payments, agreements, or deposit terms, landlords can deny or delay refunding your deposit.
How to fix it:
- Save all emails, texts, and WhatsApp messages
- Keep a digital copy of your tenancy agreement
- Take timestamped photos before you move in and out
Mistake 4: Letting the Landlord “Sort It Later”
Too many tenants are told, “Don’t worry, I’ll register it soon.” Spoiler: they often don’t.
Why it matters: Even if they protect it later, doing so beyond the 30-day legal window still makes them liable.
How to fix it: Set calendar reminders and ask for proof. If they don’t act in time, you may be able to start a tenancy deposit claim.
Mistake 5: Assuming You Can’t Do Anything Once the Tenancy Ends
One of the biggest myths we hear is: “I moved out already, so I can’t claim.” Wrong.
Why it matters: You have up to 6 years to bring a claim after the breach happened — even if you got your deposit back.
How to fix it: If you recently moved out and suspect your deposit wasn’t properly protected, get legal advice immediately.
Bonus Tip: Don’t Go It Alone
If you suspect your deposit wasn’t handled correctly, the worst thing you can do is ignore it. The law is on your side — but proving a case and getting results often requires expert support.
