An unprotected deposit now blocks your eviction

Updated July 2026 · Based on official gov.uk guidance · General information, not legal advice

Deposit protection used to be a compliance issue with a financial penalty attached. It is now a gateway to possession. If your deposit compliance is broken, the court cannot make a possession order under Section 8 at all — no matter how strong your grounds are or how much rent you are owed.

The rule. Before making a possession order, the court needs to be satisfied that one of three things is true. Either the deposit is held in an authorised scheme and the prescribed information was properly given. Or the deposit has been returned to the tenant in full, or with agreed deductions. Or any court claim about the deposit has been decided, settled or withdrawn. The only grounds excepted are the antisocial behaviour ones — Grounds 7A and 14. Rent arrears grounds are not excepted.

The timing trap that catches people out

Landlords who discover the problem often protect the deposit immediately and assume they are fine. They are not. Curing the breach does not retrospectively validate a notice served while the breach existed. If you served a Section 8 notice in June and protected the deposit in July, that June notice is dead. You fix the deposit, then serve a fresh notice, and the clock starts again.

On a Ground 8 arrears case that is four wasted weeks. On a Ground 1A case it is four wasted months. Check before you serve, every time.

The three things that must all be true

The deposit is in an authorised scheme. TDS, DPS or mydeposits. Protected within 30 days of receipt.
The prescribed information was served — within 30 days, on every tenant, and on anyone who paid the deposit on their behalf (a parent or guarantor, typically). This is the step people miss: the deposit is protected, the paperwork was never sent, and the compliance is still broken.
The certificate and scheme leaflet went with it. Keep the scheme's confirmation email and your covering email together in the property file.

Deposits taken years ago are the usual culprit. Long-running tenancies from before the current rules, deposits taken in cash and never banked, deposits held by a letting agent who has since folded, or a deposit protected in the name of one tenant when three signed the agreement. If a tenancy started more than a few years ago and you have never looked at the paperwork since, look at it now rather than on the day you need to serve notice.

How to fix it

You have two routes, and the right one depends on how long the breach has run:

Protect it late and serve the prescribed information now. This puts you back in a position to serve a valid notice going forward. It does not erase the tenant's ability to claim a penalty for the period you were in breach, but it stops the problem getting worse and it unblocks possession.
Return the deposit in full. Returning it also satisfies the gateway. If the deposit is small, the breach is long-running, and you need possession quickly, handing the money back can be the cheaper and faster option than arguing about it. Get a written acknowledgement of receipt.

Either way, do it before you serve anything, and put the evidence in the file.

Also worth knowing: a tenant can bring a claim for a penalty of between one and three times the deposit for a protection failure, and that claim can be brought after the tenancy has ended. Discovering the problem yourself and fixing it is considerably better than discovering it when a tenant's adviser raises it as a counterclaim to your possession action.

If a tenant refuses to take their deposit back

This comes up more than you would expect, usually where a tenant thinks accepting it weakens their position. Pay it into the scheme's dispute process or return it by bank transfer to the account rent came from, and document the attempt in writing. What matters is that you have properly returned the deposit or properly protected it. An obstructive tenant does not leave you stuck, as long as your record shows what you did and when.
