How to Appeal an Improvement Notice as a Landlord in England

What an Improvement Notice Means

An improvement notice is a formal enforcement action under Sections 11 and 12 of the Housing Act 2004. When an environmental health officer identifies an HHSRS hazard — typically Category 1, but sometimes Category 2 — they can serve a notice requiring you to carry out specific remedial works within a specified timescale.

Failing to comply isn't just about the original hazard. Non-compliance with an improvement notice can lead to a separate civil penalty of up to £40,000 under the updated Renters' Rights Act penalty framework. That's the number that makes the appeal deadline critical.

The 21-Day Appeal Window

You have 21 days from the date the improvement notice is served to file an appeal with the First-tier Tribunal (Property Chamber). The tribunal may allow a late appeal if it is satisfied there was a good reason for missing the deadline and for any delay in seeking permission.

The appeal form is Form HHSRS, available from GOV.UK's First-tier Tribunal (Property Chamber) forms page. It covers appeals relating to improvement notices, prohibition orders, demolition orders, and emergency measures.

What the Tribunal Considers

The First-tier Tribunal assesses the facts as they stood on the date the notice was served, not as they are at the hearing date. This is an important distinction: if you've done remedial work between the notice date and the hearing, that doesn't change whether the notice was justified when it was issued.

Grounds for appeal typically include:

• Hazard assessment error — the officer scored the hazard incorrectly, or the deficiency doesn't meet Category 1 thresholds
• Works specification problems — the required works are unreasonable, disproportionate, or technically inappropriate for the defect
• Procedural irregularity — the notice wasn't properly served or doesn't contain the information required by statute
• Mitigating circumstances — tenant access refusals prevented repair, or planning restrictions affected the building (the enforcement guidance requires councils to consider these factors)

You'll need evidence for any ground you rely on. That means your property file: maintenance records, contractor reports, access request logs, photographs, and professional assessments. Generic arguments without documentary support don't succeed at tribunal.

Practical Steps After Being Served

Day 1–3: Read the notice carefully. Identify exactly which hazard(s) are cited, what works are required, and the compliance deadline. Take your own photographs and notes of the property's current condition.

Day 3–10: Decide whether to appeal, comply, or both. You can start remedial works while an appeal is pending — doing so may strengthen a costs argument later, and it addresses the underlying hazard regardless of outcome.

Day 10–21: If appealing, complete Form HHSRS and submit it to the tribunal with supporting evidence. The current application fee is £200, with a £300 hearing fee where applicable.

If not appealing: Complete the required works within the notice timescale and provide written confirmation to the council.

Appeals Are Heard at the FTT

The First-tier Tribunal (Property Chamber) is the specialist judicial body for residential property disputes in England. It also handles Rent Repayment Order applications, rent determination challenges, and other housing enforcement appeals.

Either party can appeal a First-tier Tribunal decision to the Upper Tribunal (Lands Chamber), but only on a point of law and within 28 days of the written decision.
