More than half of UK households — 54%, according to the PDSA’s 2025 PAW Report — own a pet. Yet only around 7% of rental listings in England are advertised as pet-friendly (Inventory Base). Renting with pets in London has always meant squeezing an enormous demand through a tiny door. From 1 May 2026, the Renters’ Rights Act 2025 changes the legal position entirely. This guide explains exactly what you can now ask for, what your landlord can still refuse, and how to make a request that gets approved.
Renting With Pets in London: What Changed on 1 May 2026
Under the old rules, a blanket “no pets” line in a tenancy agreement was the end of the conversation. That is what produced the absurd gap the Dogs Trust and Cats Protection documented in their joint research: 46% of landlords say they are willing to accept pets, but only 30% of tenancy agreements permit dogs and 32% permit cats. Willingness existed; the default paperwork said no.
Section 11 of the Renters’ Rights Act 2025 flips the default. Every new private periodic tenancy from 1 May 2026 carries an implied term: you have the right to keep a pet with your landlord’s consent, and that consent cannot be unreasonably refused. The burden has moved. Your landlord no longer needs a reason to say yes — they need a defensible reason to say no.
London feels this shift more than anywhere else in the country. Around 30% of the capital’s households rent privately, the highest proportion of any English region (English Housing Survey), and London’s stock is dominated by exactly the property type where pet permission has historically been hardest to get: leasehold flats in managed blocks. The Act does not dissolve that structural problem, but it forces every refusal to be justified rather than assumed.
One important boundary: the right applies to the new-style periodic tenancies created under the Act. If you are still on a fixed-term agreement signed before the transition applies to you, check your agreement’s dates before assuming the new rules cover you. If you are a landlord reading this, our guide to what the Renters’ Rights Act means for London landlords covers the full picture beyond pets.
How the Pet Request Process Works
The Act sets out a specific procedure, and following it precisely matters — a casual mention to your landlord at a property inspection carries no legal weight. The mistake we consistently see London renters make is asking verbally, getting a vague “I’ll think about it”, and having nothing to point to three months later. Put it in writing from day one.
- Submit the request in writing, describing the pet: species, breed, age, and anything relevant such as training or previous rental history.
- The landlord has 28 days to respond — granting consent, refusing with reasons, or asking for more information.
- If the landlord asks a reasonable follow-up question, the clock extends; the same applies where a superior landlord’s consent is needed, which is common in London flats.
- A refusal must be in writing and must state the reason. Silence past the deadline is not a lawful refusal.
Keep every email. If a dispute reaches the Private Rented Sector Ombudsman or a court later, the paper trail is the case.
When Can a London Landlord Still Refuse a Pet?
Here is the honest part most pet-rights coverage skips: plenty of refusals will remain perfectly reasonable, and London’s housing stock makes some of them unavoidable. The Act does not define “reasonable” exhaustively — that will be shaped by ombudsman decisions and case law — but the clear categories look like this.
| Likely reasonable refusal | Likely unreasonable refusal |
|---|---|
| The head lease on the flat prohibits pets — extremely common in purpose-built blocks in Zones 1–3, and the landlord cannot override it | “We just don’t allow pets” with no reason specific to the property or the animal |
| A large dog in a studio with no outdoor access, raising genuine welfare concerns | Refusing a caged animal or an indoor cat in an ordinary self-contained flat |
| Documented allergies of other tenants in an HMO or house share | A blanket policy applied across a landlord’s whole portfolio regardless of circumstances |
If you are flat-hunting with a dog, this is worth internalising: a Victorian conversion or a house share with a garden in Walthamstow or Lewisham is a structurally easier “yes” than a leasehold flat in a managed block, whatever the Act says. Our guide to the best London areas for pet owners ranks neighbourhoods where the housing stock and green space actually work in your favour.
Three London Scenarios: How Pet Requests Actually Play Out
The dog owner in a Zone 3 terrace
You rent a two-bed Victorian terrace in Walthamstow with a garden, and you want a rescue labrador. This is the strongest possible case under the new rules. The property is freehold or on a lease with no pet covenant, the garden answers the welfare question, and a refusal would need a reason specific to you or the dog. Submit the written request with a previous landlord reference and expect a yes — a refusal here is exactly the kind the ombudsman route exists to overturn.
The cat owner in a managed block
You rent a one-bed in a 2010s development in Canada Water and want an indoor cat. Everything now hinges on the head lease. If it prohibits pets, your landlord’s refusal is reasonable and final — argue with the freeholder’s covenant, not your landlord. If it is silent or permits pets with consent, an indoor cat in a self-contained flat is very hard to refuse reasonably. Ask your landlord to confirm the head-lease position in writing within the 28-day window, because “the block probably doesn’t allow it” is not a stated reason.
The house-sharer in an HMO
You share a four-bed house in Willesden with three strangers and want a dog. Expect this to be the hardest yes in London. A landlord citing another tenant’s documented allergy, or the practical welfare of a dog left in a shared house all day, is likely on solid ground. Your realistic path is a smaller caged pet, or moving to a two-person share where the other tenant actively agrees. Knowing when the law is not on your side saves you a 28-day wait and a failed dispute.
Pet Deposits, Pet Rent and the Insurance U-Turn
Money is where landlords and agents will test the boundaries, so know them precisely.
The original Renters’ Rights Bill let landlords require tenants to hold pet damage insurance as a condition of consent. The Government removed that provision by amendment at the House of Lords report stage in 2025 — it did not survive into the final Act. Your landlord cannot make insurance a condition of saying yes.
The Tenant Fees Act 2019 still caps your deposit at five weeks’ rent where the annual rent is under £50,000, and the Renters’ Rights Act did not create a separate additional “pet deposit”. Run the numbers on what that cap means in practice: at London’s average rent of £2,290 a month (ONS Price Index of Private Rents, April 2026), the maximum deposit is about £2,640 — with a pet or without one. Any agent asking for “an extra two weeks for the dog” is asking for a prohibited payment, and you can report it to your borough’s trading standards team. Pet damage comes out of the ordinary deposit like any other damage — and a landlord cannot recover the same damage twice. Some London agents spent 2025 quietly adding £25–£50 a month of “pet rent” to listings; the Act does not explicitly ban charging a higher headline rent for consent, but a demand bolted on after you have signed is challengeable. If you paid a deposit and are worried about pet-related deductions at the end of your tenancy, read our guide on how to get your full deposit back.
How to Write a Pet Request That Gets Approved
The legal right gets you a hearing. The quality of your request gets you the yes. Landlords are risk-averse, not pet-hating — a request that removes risk from their side of the table usually succeeds.
- Describe the animal specifically: “a four-year-old neutered cocker spaniel, crate-trained, never left alone for more than four hours” beats “a dog”.
- Attach a reference from a previous landlord confirming no pet damage — this is the single most persuasive document you can include.
- Offer a professional end-of-tenancy clean in writing. It costs £150–£250 for a typical London flat and removes the landlord’s most common fear.
- Mention voluntarily held pet insurance if you have it. They cannot require it; offering it anyway signals seriousness.
- For flats, ask the landlord to check the head lease early — it saves both sides 28 days of waiting for an inevitable answer.
Refused Unreasonably? Here Is What to Do
Do not move the pet in and hope. Breaching your agreement hands the landlord a clean grievance and muddies an otherwise strong position.
Build your evidence file before you escalate. That means the original written request, the refusal (or proof that 28 days passed in silence), photographs of the property showing why it suits the animal, and — if the landlord cited the head lease — a written request that they produce the relevant clause. Landlords who refuse on grounds they cannot document lose these disputes; tenants who escalate on feelings rather than paperwork lose them too.
Then reply in writing asking the landlord to reconsider, stating why the refusal is unreasonable against the specific property and animal. If they hold their position, escalate to the Private Rented Sector Ombudsman that the Act establishes for exactly these disputes — it is free for tenants, unlike court. Citizens Advice and Shelter both publish current guidance on the process and will sanity-check your case before you file. Expect the first year of ombudsman decisions to define where the “reasonable” line sits; early, well-documented complaints are the ones that will set it favourably.
Practical Takeaways
- From 1 May 2026, landlords of new periodic tenancies cannot unreasonably refuse a written pet request — and must respond within 28 days with reasons (Renters’ Rights Act 2025, s.11).
- Head-lease bans in London flat blocks remain a legitimate refusal ground. Target houses, conversions and garden properties if you have a dog.
- No pet insurance requirement survived into the final Act, and no separate pet deposit exists — the standard five-week cap still applies.
- Ask in writing, attach a previous landlord reference, and offer a professional clean — requests built this way remove the landlord’s actual objections.
- If refused unreasonably, escalate to the Private Rented Sector Ombudsman rather than moving the pet in quietly.
