The Renters’ Rights Act 2025 Pet Rules and What They Mean for Your Animal

In force since 1 May 2026 · Renters’ Rights Act 2025

The Renters’ Rights Act 2025 received Royal Assent on 27 October 2025, and its pet provisions came into force on 1 May 2026. Section 11 inserts sections 16A and 16B into the Housing Act 1988, giving a tenant on an assured tenancy in the private rented sector a right to ask the landlord for permission to keep a pet, which the landlord must not unreasonably refuse.

Read this first. The Act deals with pets. It does not create emotional support animal status, and it gives a medical letter no legal effect. The UK has no register or certification scheme that confers assistance animal status, and no document, from any doctor or any organisation, makes a landlord accept an animal. In law a companion animal that is not a trained assistance dog is a pet, so the section 11 pet request route is the one that applies to it.

This guide sets out what section 11 actually says, where the Equality Act 2010 does and does not help a tenant, and what a doctor’s letter can and cannot do in a housing request.

What the Renters’ Rights Act 2025 Changed for Pet Requests

Since 1 May 2026 the following applies. The right is created by section 11 of the Renters’ Rights Act 2025, which inserts sections 16A and 16B into the Housing Act 1988. Section 16A(6) applies it to every assured tenancy other than a tenancy of social housing, so social housing tenants are outside this route and should ask their landlord what its own pet policy allows.

The Default Has Shifted to Permission

Section 16A implies a term into the tenancy that a tenant may keep a pet if the tenant asks and the landlord consents, and that consent is not to be unreasonably refused. The request must be in writing and must include a description of the pet, which section 16B(3) requires. The landlord must give or refuse consent in writing on or before the 28th day after the date of the request. A landlord who does not respond in time, or who refuses without a reasonable ground, is in breach of that implied term. The starting point has moved from no pets unless stated otherwise to a framework in which a refusal has to be justified. Nothing in the section turns on why the tenant wants the animal.

Grounds for Refusal Must Be Reasonable

A landlord may only refuse on reasonable grounds. Section 16B(4) names circumstances in which refusal is reasonable, and both of them concern a superior landlord: where keeping the pet would put the landlord in breach of an agreement with a superior landlord, and where such an agreement requires the superior landlord’s consent and the landlord has taken reasonable steps to obtain it but has not been given it. That list is expressed as circumstances which are included, so it is not exhaustive, and the Act names no other ground. What else counts as reasonable, such as a property genuinely unsuitable for the particular animal, will be worked out through guidance and case law. A general dislike of animals, or a blanket policy applied without looking at the request, will not.

How the 28 Days Can Be Extended

The Act sets out three ways the deadline can move, and no overall long-stop date.

• If the landlord reasonably asks for further information about the pet on or before day 28, they may delay until the 7th day after the tenant provides it. If the tenant does not provide it, the landlord is not required to respond at all.
• If the landlord needs a superior landlord’s consent and seeks it on or before day 28, they may delay until the 7th day after they receive that answer.
• The landlord and tenant may simply agree a later date.

Where more than one of these applies, the landlord may take the latest of the resulting dates. Some earlier commentary described a 35 day maximum. The Act contains no such cap.

Where Medical Need Fits, and Where It Does Not

Section 11 says nothing about health, disability, medical need, emotional support animals or assistance animals. The right is the same whether the animal is a companion, a working dog or a hamster, and a doctor’s letter does not convert a pet request into a stronger legal claim under the Act.

What a letter can do is factual. Reasonableness is judged on the circumstances, so a landlord weighing a request is entitled to know the context, and a tenant is entitled to explain it. A letter from a GMC-registered doctor describing a diagnosed condition and the role a companion animal plays in managing it is one piece of context among several. It is not evidence a landlord is obliged to accept, and it does not shift the legal test.

Interaction With the Equality Act

The Renters’ Rights Act does not replace the Equality Act 2010, it sits alongside it. A tenant who meets the Equality Act definition of disability can also ask for a reasonable adjustment to a no-pets term under Part 4 and Schedule 4, and that is a separate route with its own test and its own remedy in the county court.

What that route is not is an assistance dog exemption. The Equality Act’s only statutory definition of an assistance dog is in section 173, and section 173 applies to Chapter 1 of Part 12, which is about taxis and private hire vehicles. The access rights people usually have in mind, the ones about shops, restaurants and hotels, come from Part 3, which covers services and public functions. Section 28(2)(a) states that Part 3 does not apply to discrimination prohibited by Part 4, and housing is Part 4. So the assistance dog reasoning that works against a service provider does not carry across to a landlord. A disabled tenant’s route in housing is a reasonable adjustment claim, not an assistance dog exemption.

The Role of Medical Documentation

It helps to be clear about what a letter is for. A doctor’s letter is not a licence, a permit or a certificate of status, and there is nothing in UK law for it to register the animal with. Its value is evidential and it is limited.

A letter from a GMC-registered doctor can confirm a diagnosed condition, such as anxiety, depression or PTSD, and describe the part a companion animal plays in managing it. That gives a landlord, or later a court, something concrete instead of an assertion. Under the Equality Act route it also goes to the threshold question of whether the tenant is disabled within the meaning of the Act, which is where many reasonable adjustment claims are actually decided.

Shelter’s guidance on the pet rules is blunt on the wider point. It states that emotional support animals are not legally recognised in the UK, and that landlords and other organisations therefore have no legal duty to make special allowances for them. Anyone selling a letter as though it created such a duty is misdescribing it. Read the Shelter England guidance alongside this page.

An emotional support animal is also not an assistance dog. An assistance dog is trained to perform tasks for a disabled person, and the Equality Act defines the term only in section 173, for taxis and private hire vehicles. There is no UK register or certificate that confers assistance dog status, and buying a letter, harness, vest or identity card does not create it. An untrained companion animal is a pet, and the pet request route is the one that applies.

The clinical review for an emotional support animal letter covers your condition and the animal’s role in managing it, and produces a letter written for housing correspondence. Whether a landlord agrees remains the landlord’s decision.

For tenants dealing with mental health-related housing needs more broadly, a mental health support letter can document conditions relevant to housing allocation and tenancy management discussions.

Social housing tenants are outside the section 16A pet route. Where a health condition affects a council or housing association application or transfer instead, our housing support medical letter is written for that assessment.
