Reasonable Refusal of a Pet Request: What Landlords in England Can and Cannot Do

The Legal Standard

Section 16A(1)(b) of the Housing Act 1988 says you must not unreasonably refuse consent to a tenant's pet request. That is not the same as saying you must always say yes. You can refuse — but only on objective, evidence-based grounds that relate to the property, the tenancy, or the specific animal.

The test is fact-sensitive. A refusal that is reasonable for one property may be unreasonable for another.

Grounds That Are Likely Reasonable

Property size constraints. A large dog in a studio flat with no outdoor access is a genuine welfare and suitability concern. The smaller the property and the larger the animal, the stronger the case. MHCLG guidance recognises property size as a relevant factor.

Head lease or building prohibition. If keeping the pet would breach an outright prohibition in your head lease, that can be a reasonable ground for refusal. If the lease allows pets only with freeholder consent, you must take reasonable steps to seek consent; if the freeholder does not give it, that can be a reasonable ground. To use the statutory deadline extension, seek any required consent by the 28th day after the request.

Documented medical allergy in a shared property. In an HMO or building with shared communal areas, a severe documented allergy among other occupants can justify refusal. "Allergy" without clinical evidence is unlikely to hold up in a dispute.

Animal welfare concerns. If the property cannot safely house the animal — no ventilation for reptile enclosures, no garden for a dog that needs outdoor exercise — you can point to genuine welfare issues.

Licensing restrictions. Some HMO licences or selective licensing conditions may include specific conditions about property use or animal-keeping. Check the actual wording of your licence.

Grounds That Are Unlikely to Hold Up

A blanket "no pets" clause in the tenancy agreement. Section 16A overrides these. The implied statutory term replaces any express term that tries to block the process entirely.

"I just don't want pets in my property." Personal preference is not an objective ground. You must point to a property-specific, evidence-based reason.

"Pets cause damage." All tenants might cause damage. The existence of deposit protection and inventory protocols exists precisely for this. A generalised fear of damage is not a reasonable refusal.

"The neighbours might complain." Hypothetical future complaints from third parties are speculative, not evidence-based.

How to Write a Defensible Refusal

If you do refuse, the refusal must be in writing and issued before the statutory deadline. It should state objective grounds. Vague language weakens your position. Instead of "the property is unsuitable," write "the property is a 28 sqm studio flat on the fourth floor with no balcony or garden access, which does not provide adequate space or outdoor exercise for a medium-sized dog breed."

Keep a copy of every document: the original request, your refusal letter, any supporting evidence (head lease clauses, allergy documentation, HMO licence conditions), and dated correspondence.

The Tenant Pet Requests guide includes pre-drafted refusal letter templates covering the most common grounds — property size, head lease restriction, allergy, and HMO constraints — so you can adapt the wording to your specific situation rather than drafting from a blank page.

What Happens If the Tenant Challenges Your Refusal

The tenant can apply to the County Court under Section 16B(5). The court will assess whether your refusal was objectively reasonable. If it was not, the court can order specific performance — meaning you must grant consent — and may award costs against you. A well-documented, evidence-based refusal letter is your strongest defence.
