Nearly two-thirds of UK tenants who own pets say they have struggled to find a rental property that will accept them, according to recent surveys. That figure alone tells you how much tension exists between wanting a home for yourself and your animal, and the reality of what landlords are willing to allow. I have been writing about UK rental law for long enough to see this pattern repeat: tenants assume a polite request will be enough, landlords assume a blanket “no pets” clause protects them, and both sides end up frustrated when the rules shift beneath them.
The Renters’ Rights Act 2025, which becomes law on 1 May 2026, changes the old system completely. Blanket “no pets” clauses in tenancy agreements will no longer be enough on their own. Landlords will have to consider each request individually and can only refuse on reasonable grounds. That is a big shift, and it affects every tenancy signed or renewed after that date. If you are renting with a pet — or planning to — you need to understand how this works before you sign anything. Here is what you actually need to know.
I have covered tenant protections in the UK extensively, and this change is one of the most practical for pet owners. A monitored alarm system like the Yale Smart Home Alarm can help protect your deposit by alerting you to potential issues while you are out — but more on practical steps later.
How the new pet request process actually works
The most important thing to understand is that the law does not give you an automatic right to keep a pet. You still have to ask. But the rules around how landlords can respond have tightened considerably. From 1 May 2026, a tenant must submit a formal written request that includes a description of the pet for which consent is sought. That wording matters — it means you are not asking for permission to keep “a cat” in general, but for a specific animal.
If you get permission for a particular pet and that animal later dies or moves out, you cannot simply replace it without submitting a fresh request. The consent is tied to that specific animal. That is a detail many tenants miss, and it can cause problems if you assume the permission carries over. What I would do is keep a copy of every written request and the landlord’s response, dated and filed, so there is no ambiguity later.
Why this matters for tenants with pets right now
The practical effect of the new rules is that tenants who own pets will have more leverage than they have had in years. But that leverage only works if you follow the process correctly. The guidance from the Landlord Association makes clear that a landlord’s personal dislike of animals, previous negative experiences with tenants who had pets, or concerns about future damage are not reasonable grounds for refusal. That closes off the most common excuses landlords have used in the past.
Consider this scenario: you live in a one-bedroom flat and want to keep a small dog. Under the old system, a landlord could simply point to a “no pets” clause and refuse. Under the new rules, they would need to show that the property is genuinely unsuitable in size or condition for that specific dog. If the flat has a small garden and the dog is a low-energy breed, that refusal becomes much harder to justify. The same logic applies to leasehold flats where the landlord’s own head lease prohibits pets — that is one of the few situations where a refusal is likely to be considered reasonable.
I have noticed that many tenants assume they need to wait until their tenancy renewal to raise the pet question. That is not true. The statutory right applies once a tenancy is underway, so you can submit a request at any point during the fixed term. Landlords still retain the ability to decide whether to grant a tenancy to a prospective tenant who already has a pet, but once you are in the property, the new rules protect your request.
A pet-proof flooring protector can help you avoid disputes over damage at the end of your tenancy, which is one less thing to worry about when you make your request.
Where tenants and landlords get the process wrong
The most common mistake I see is treating the pet request as a casual conversation. A verbal agreement with a landlord is not worth the paper it is not written on. The law requires a formal written request with a description of the specific pet. Without that, the 28-day clock never starts, and you have no legal protection if the landlord later changes their mind.
| Reasonable grounds for refusal | Not reasonable grounds |
|---|---|
| Another tenant has a verified allergy to the pet | Landlord personally dislikes pets |
| Property is too small or unsuitable for the specific animal | Previous tenants with pets caused damage |
| The pet is illegal under the Dangerous Dogs Act 1991 or Dangerous Wild Animals Act 1976 | General concern about future wear and tear |
| The landlord’s own head lease or freeholder rules prohibit pets | Landlord had a bad experience with a different tenant’s pet |
Assuming consent covers any future pet
This is the second most common error. If you get permission for a specific cat, that permission does not extend to a second cat or a replacement cat. Each animal requires its own written request. Landlords are entitled to assess each pet individually, and a tenant who assumes otherwise risks being in breach of the tenancy agreement. What I would do is submit a fresh request every time the animal situation changes, even if it feels repetitive.
Not understanding the difference between pets and assistance animals
Under the Equality Act 2010, assistance animals are not legally classed as pets. If you have a disability and require an assistance animal, landlords are generally expected to permit this as a reasonable adjustment. They cannot increase the rent or require a higher deposit. Emotional support animals do not have the same automatic legal recognition in the UK, so those requests should be assessed on a case-by-case basis. Mixing these up can lead to unnecessary disputes.
Ignoring the 28-day response deadline
Landlords have 28 days to respond to a written pet request. If they ask for additional information, they must respond within seven days of receiving it, or within the remainder of the original 28-day period, whichever is later. If no written refusal is issued within that window, consent is automatically granted. Tenants who do not track this deadline miss a significant legal advantage. Keep a dated copy of your request and note the deadline on your calendar.
If you are unsure whether your landlord’s refusal is reasonable, speaking with a tenant landlord lawyer can clarify your options before the situation escalates.

The process is straightforward if you follow the steps in order. Here is exactly what to do, from preparing your request to dealing with a refusal.
Prepare your written request properly
Your request must be in writing and include a description of the specific pet. That means the species, breed, age, and any relevant details about size or temperament. Do not write “I would like to keep a cat.” Write “I am requesting permission to keep a three-year-old neutered domestic shorthair cat named Jasper, weighing approximately 4 kg.” The more specific you are, the harder it is for the landlord to claim the request is vague. Send the request by email or recorded delivery so you have proof of the date it was received.
Track the 28-day response window
Once the landlord receives your written request, the clock starts. Mark the deadline on your calendar. If the landlord asks for more information — for example, proof that the pet is vaccinated or a reference from a previous landlord — respond promptly. The clock pauses only for the time it takes you to provide that information. If the 28 days pass without a written refusal, consent is automatically granted. Keep that written confirmation of delivery safe.
What to do if the landlord refuses
If the landlord refuses in writing, check whether the reason given is one of the reasonable grounds listed in the guidance. If the refusal is based on something like personal dislike or past damage by a different tenant, you may have grounds to challenge it. Tenants who believe a refusal is unreasonable can complain to the forthcoming Landlord’s Ombudsman, expected to be operational around 2028, or apply to the courts for an order of specific performance under section 16B(5) of the legislation. In practice, most disputes are resolved before court if the tenant has clear documentation.
Future-proofing your tenancy for pets
If you are looking for a new rental and already have a pet, the landlord can still choose not to grant you the tenancy. The statutory right applies once you are in the property, not during the application stage. That means you may need to be upfront about your pet during viewings. Some landlords will be more open if you offer a pet reference from a previous landlord or evidence that your animal is well-behaved. A secure pet carrier can also help during viewings by showing you take responsible pet ownership seriously.
