The 1 May 2026 commencement of section 11 of the Renters' Rights Act 2025 changed the legal architecture around pets in let property in England. Until that date, the question was a matter of contract: the tenancy agreement either permitted pets, prohibited them, or made consent conditional on landlord agreement, and that was the end of the analysis. From 1 May 2026, the question is a matter of statute: every assured tenant has a right under section 16A of the Housing Act 1988 (as inserted by RRA 2025 s.11) to request consent to keep a pet, and the landlord is bound by an implied term not to refuse unreasonably. This page sets out the operational decision tree.
For the broader context of the RRA 2025 reforms (Section 21 abolition, the new Section 8 grounds, periodic tenancies as default), see our companion pages on Section 21 abolition, periodic tenancy default mechanics, and civil penalty defence.

What the Enacted Act Actually Says (and What it Does Not)
Section 11 of the RRA 2025 inserts two new sections into the Housing Act 1988: section 16A (requesting consent to keep a pet) and section 16B (further provision). A definition of 'pet' is added at section 45(1) of the 1988 Act. No other operative provision on pets sits in the enacted text.
The mechanic is short. Section 16A(1) implies into every assured tenancy a term that the tenant may keep a pet at the dwelling-house if (a) the tenant has requested the landlord's consent in writing, (b) the landlord has consented, and (c) the landlord has given or refused consent in writing on or before the 28th day after the date of the request. The 28-day deadline can be extended in three defined situations under section 16A(2) to (5): a landlord request for further information about the pet, a landlord application for superior-landlord consent, or a mutually agreed longer period. Section 16A(6) excludes social housing from the scope; otherwise it covers all assured tenancies.
Section 16B fills out the operational detail. Subsection (1) defines when a pet is 'kept' (broad: ownership by the tenant is not required; a partner moving in with their existing dog triggers the regime). Subsection (3) requires the tenant's request to be in writing and to describe the pet. Subsection (4) sets out the only reasonable refusal grounds: (a) keeping the pet would cause the landlord to be in breach of an agreement with a superior landlord, or (b) superior-landlord consent is needed and has been refused despite the landlord taking reasonable steps. Subsection (5) provides the remedy: specific performance, applied for in the County Court.
What the Act does NOT contain
Three items featured in earlier Bill drafting and in much of the pre-enactment press coverage but did NOT make it into the enacted text:
- Pet damage insurance as a consent condition. The Bill carried a provision allowing landlords to require the tenant to take out pet damage insurance as a condition of consent (drafted as an exception to the Tenant Fees Act 2019 prohibition on additional charges). This provision was removed before Royal Assent. The Tenant Fees Act 2019 prohibition therefore applies in full: a landlord cannot require the tenant to take out pet insurance, cannot charge a pet bond or additional deposit, and cannot include any pet-related fee outside the prescribed list.
- Broader reasonable-refusal grounds. Earlier drafting referenced building insurance constraints, layout or size unsuitability, and general damage-risk concerns as potential reasonable-refusal grounds. The enacted section 16B(4) is restricted to the two superior-landlord grounds only. A landlord refusing on building-insurance or layout grounds is at risk of an unreasonable-refusal finding.
- Tribunal route. Some press coverage anticipated a First-Tier Tribunal Property Chamber route on contested refusals. The enacted text provides for County Court specific performance under section 16B(5) only. The procedural protection is heavier than a tribunal route would be, in both directions.
Landlords advised before May 2026 on the basis of the in-passage Bill drafting (and there is a substantial volume of such advice in circulation as of 22 May 2026) should re-anchor on the enacted text. The narrow refusal scope under section 16B(4) and the absence of the insurance provision are the two corrections that most often catch landlords out.
The 28-Day Response Mechanic
The clock starts on the date the landlord receives the tenant's written request (which must, under section 16B(3), describe the pet). The standard deadline is 28 days from that date. The three extensions:
| Extension | Section | How it works |
|---|---|---|
| Request for further information | s.16A(2) | Landlord requests further information about the pet within the original 28 days; deadline extended to 7 days after tenant provides the information |
| Superior-landlord consent | s.16A(3) | Landlord writes to the superior landlord within the original 28 days; deadline extended to 7 days after superior landlord responds |
| Mutually agreed longer period | s.16A(4) | Landlord and tenant expressly agree a longer period in writing |
| Multiple extensions apply | s.16A(5) | The latest applicable date governs (so a landlord engaging both s.16A(2) and (3) takes the longer of the two) |
Failure to respond within the operative deadline is not automatically deemed consent under the section text. The realistic exposure is a section 16B(5) court application by the tenant for specific performance, where the court will treat continued silence as evidence of unreasonableness and is likely to grant the order with costs. The disciplined posture is to respond in writing every time, even where the response is itself a request for further information under section 16A(2) or a notification under section 16A(3) that superior-landlord consent is being sought. Silence is the worst possible posture.
The Narrow Reasonable-Refusal Test (Section 16B(4))
Section 16B(4) lists the only two situations in which a refusal is treated as reasonable. The drafting is closed (not a non-exhaustive list); refusal on any other basis is at risk of being treated as unreasonable.
Ground 1: superior-landlord agreement breach
The landlord's own lease from the freeholder, or any superior landlord in the chain, prohibits the keeping of pets, and granting consent would put the landlord in breach of that superior agreement. The standard fact pattern: a buy-to-let flat in a leasehold block where the headlease contains an unqualified 'no pets' covenant. Refusal on this ground is reasonable because consent would expose the landlord to a forfeiture risk from the freeholder.
Practical mechanic: on receipt of the request, the landlord reads the headlease to confirm the prohibition, writes to the superior landlord within 28 days if any superior-landlord consent process is engaged, and responds to the tenant within the operative deadline citing the headlease term. The headlease text and any superior-landlord correspondence should be retained as audit-trail evidence. A landlord who fails to engage with the superior landlord at all (where the superior-landlord consent route is open) cannot rely on Ground 1 because the steps to obtain consent have not been taken.
Ground 2: superior-landlord refusal after reasonable steps
The landlord has sought superior-landlord consent (typically because the headlease contains a 'consent not to be unreasonably withheld' clause or similar), has taken reasonable steps to obtain that consent, and the superior landlord has nonetheless refused. The refusal then cascades down: the landlord cannot grant consent because the superior landlord has refused, and refusal of the tenant's request is reasonable on that cascade.
'Reasonable steps' is fact-specific but at a minimum includes a written request to the superior landlord, provision of the pet description from the tenant's section 16B(3) request, and engagement with any reasonable conditions the superior landlord proposes. A landlord who writes a single letter and accepts a one-line 'no' without enquiry is unlikely to have taken reasonable steps; a landlord who has corresponded substantively with the freeholder, addressed the freeholder's stated concerns, and received a reasoned refusal is in a strong position.
What is NOT a reasonable refusal ground
- General preference against pets in the property.
- Concern about damage risk in the abstract (the security deposit and the landlord's own insurance carry that risk).
- Building insurance constraint where the constraint is internal to the landlord's own policy rather than a superior-landlord requirement.
- Property size or layout, considered in isolation.
- The tenant's existing tenancy contract containing a 'no pets' clause (this is overridden by the statutory implied term under section 16A from 1 May 2026).
- Other tenants in an HMO not wanting a pet in the shared property (unless this engages a defensible separate regulatory ground, such as an HMO licence condition).
A landlord facing fact patterns that feel like they should support refusal but do not fit Ground 1 or Ground 2 should consider whether a defensible separate regulatory ground exists outside section 16B(4) (HMO licence condition; planning condition on the property; protected-species concerns). These sit outside the section 11 framework but may provide a parallel defensible position. Specialist housing counsel is the right channel for edge cases.
The Tenant Fees Act 2019 Interaction
The Tenant Fees Act 2019 prohibits a landlord (or anyone acting on the landlord's behalf, including letting agents) from requiring a tenant to make any payment in connection with a tenancy other than: rent, a refundable tenancy deposit within the 5-week cap (or 6 weeks for properties with annual rent at or above £50,000), a refundable holding deposit, and default fees in defined circumstances (late rent payment; lost-key replacement). The list is exhaustive.
Pet-related charges fall outside the prescribed list. The combined effect of the enacted RRA 2025 (which removed the original Bill's pet damage insurance provision before Royal Assent) and the Tenant Fees Act 2019 prohibition is that a landlord cannot:
- Require the tenant to take out pet damage insurance as a consent condition.
- Charge a 'pet bond' or 'pet deposit' beyond the 5-week (or 6-week) deposit cap.
- Add a 'pet rent' premium on top of the agreed rent (a higher initial rent is permissible if it is the genuine market rent; an artificial uplift presented as 'pet rent' is at risk of being treated as a prohibited fee).
- Charge a 'pet cleaning fee' at the end of the tenancy outside the default-fees framework (end-of-tenancy cleaning is recovered from the deposit, not as a separate fee).
The landlord's response to the pet damage risk is therefore commercial rather than contractual: review the landlord insurance policy to confirm pet damage is covered (most standard landlord policies cover tenant-caused damage with a marginal premium uplift for pet-included cover), and rely on the deposit + insurance combination to manage the residual risk. The premium uplift is a deductible landlord-insurance expense (covered below).
The Landlord's Practical Decision Tree
On receipt of a written pet request, the landlord works through the following sequence within 28 days:
- Verify the request is written and contains a pet description (section 16B(3)). If oral or undescribed, request a written description within 28 days under section 16A(2). The clock pauses.
- Read the headlease. If the headlease contains an unqualified pet prohibition: refuse under Ground 1, citing the headlease term. Keep the headlease text and the refusal letter in the audit trail.
- If the headlease contains a 'consent not unreasonably withheld' clause or similar: write to the superior landlord within 28 days with the pet description. The 16A(3) extension applies. Follow up with reasonable steps to obtain consent.
- If the headlease is silent on pets: no Ground 1 or Ground 2 defence is available. Consider consent. If you wish to refuse, you must identify a defensible separate regulatory ground (HMO occupancy density, planning condition) and document it carefully; consider specialist housing counsel.
- If consent is to be granted: respond in writing within 28 days confirming consent. Do NOT attach prohibited conditions (no insurance requirement, no pet deposit, no pet rent uplift). You may attach reasonable behavioural conditions (notification of changes to the pet, basic veterinary care, observance of leasehold quiet-enjoyment standards).
- Document the entire decision sequence. Request date, response date, headlease text, superior-landlord correspondence, reasoning. This is the audit trail if the tenant subsequently applies to the County Court for specific performance.
Tax Treatment: Landlord Insurance, End-of-Tenancy Spend, and Professional Fees
The deductibility framework on the landlord side is straightforward and sits within the standard wholly-and-exclusively rule in ITTOIA 2005 s.34 (cash basis) and s.272 (accruals applying trading-profit principles), backed by HMRC's Property Income Manual at PIM2080 (revenue expenses) and PIM2090 (allowable expenses checklist).
| Cost | Cap or revenue | Deductible? | Authority |
|---|---|---|---|
| Landlord insurance premium (standard policy) | Revenue | Yes, in year of payment (cash basis) or matched (accruals) | ITTOIA 2005 s.272; PIM2080 |
| Landlord insurance premium uplift for pet-included cover | Revenue | Yes | As above |
| End-of-tenancy professional clean | Revenue | Yes | ITTOIA 2005 s.272; PIM2030 |
| Like-for-like replacement of pet-damaged carpet | Revenue | Yes | PIM2030 (like-for-like / modern equivalent) |
| Full carpet replacement throughout to upgraded specification | Capital (or apportionment) | No (or partial); adds to CGT base cost | PIM2030 |
| Pet damage to structural element (skirting, doors) | Revenue (repair) or capital (replacement) | Apportionment by component | PIM2030 |
| Legal fees defending a section 16B(5) court application | Revenue | Yes (revenue-shape: defending operational lettings, not capital structure) | ITTOIA 2005 s.272 |
| Tenant's own voluntary pet insurance | n/a | Not deductible by landlord (tenant's expense) | Not the landlord's outlay |
| 'Pet deposit' or 'pet bond' charged to tenant | n/a | Not lawful to charge in the first place | Tenant Fees Act 2019 |
The deduction is taken in the year of payment under the cash basis (default for landlords with gross rental income under £150,000) or matched to the period the expense relates to under the accruals basis. Recoveries from the deposit at end of tenancy are credited against the deduction in the same accounting period (so a £400 carpet replacement recovered £300 from the deposit produces a net £100 deduction). The deductibility framework is the same one developed in detail in our HMO licensing fees deductibility guide; the principles carry across cleanly.
Worked Example: 2-Bedroom Leasehold Flat, Pet Request Process
An anonymised illustration. A landlord owns a 2-bedroom flat on a 99-year lease in a 1990s Inner London block, let on an assured periodic tenancy from 1 May 2026 conversion. Annual rent £24,000. Tenant submits a written request on 3 June 2026 for permission to keep a Cavalier King Charles Spaniel puppy (description, age, vaccination record provided).
Step 1 (received 3 June): landlord logs the request, diaries the 28-day deadline (1 July 2026). Reads the headlease. Headlease contains: 'No animal, bird, reptile or fish (other than ornamental fish in tanks not exceeding 75 litres) shall be kept in the flat without the prior written consent of the lessor, such consent not to be unreasonably withheld.' This is the 'consent not unreasonably withheld' pattern, engaging Ground 2 of section 16B(4).
Step 2 (5 June): landlord writes to the freeholder with the pet description, enclosing the tenant's section 16B(3) request, asking for the freeholder's consent. The 16A(3) extension applies; the new deadline is 7 days after the freeholder responds.
Step 3 (24 June): freeholder responds confirming consent on the conditions that (a) the pet is no larger than 10kg, (b) the tenant carries third-party liability insurance covering pet-caused damage to common parts of the block, (c) the pet is registered with a local vet and vaccination records maintained. The Cavalier King Charles Spaniel comfortably meets (a). Conditions (b) and (c) are matters for the tenant to attend to; the landlord cannot require pet insurance as a consent condition between landlord and tenant, but the freeholder's separate condition on the tenant's third-party-liability cover for common-parts damage is enforceable through the freeholder's covenant route (and against the landlord under the headlease).
Step 4 (26 June, within the 7-day post-freeholder window): landlord writes to the tenant confirming consent. The consent letter includes: (a) confirmation that the tenant may keep the described pet at the dwelling, (b) the freeholder's conditions (size limit, common-parts liability cover, vet registration) passed through as conditions imposed by the superior landlord which the tenant must observe, (c) standard behavioural expectations (notify the landlord of changes to the pet; ensure the pet does not unreasonably disturb other occupiers; maintain the property to the usual standard at end of tenancy). The consent letter does NOT require the tenant to take out pet damage insurance for the landlord's benefit (prohibited by the Tenant Fees Act 2019 in the absence of an enacted exception), does NOT add a pet deposit or pet rent (also prohibited), and does NOT add cleaning-fee provisions (recovered through the deposit at end of tenancy).
Tax treatment for the landlord:
- Landlord's existing buy-to-let insurance policy is upgraded to a pet-included variant at a £45 annual premium uplift. Deductible in full in the year of payment under the cash basis. At higher-rate income tax (40%), the £45 deduction is worth £18 in tax relief; net cost £27.
- Legal fees of £180 for an external solicitor to review the headlease and draft the consent letter on a fixed-fee basis (one-off, not a recurring legal cost). Revenue, deductible. Net cost £108.
- End of tenancy, 18 months later: professional clean £220, like-for-like replacement of a damaged carpet section in the lounge £350. Both revenue, deductible. Recovered £400 from the deposit. Net deduction £170 against the original £570 outlay.
- Total pet-related deductible spend across the tenancy: £45 + £180 + £570 = £795 gross, deductible against rental income.
- Higher-rate income tax relief: £318. Net pet-related cost to the landlord across the tenancy: £77 net of tax recoveries and deposit deductions.
The structural point: the operational and financial cost of consenting to a reasonable pet request, on the proper enacted-Act framing, is small and predictable. The cost of refusing unreasonably (court application by the tenant, legal fees defending the application, the eventual order to consent anyway, plus the tenant's costs awarded against the landlord) is materially larger. The new statutory framework is restrictive on landlords by design; the operationally sensible response is to engage with reasonable requests, document the decision sequence carefully, and refuse only where Ground 1 or Ground 2 of section 16B(4) is actually engaged on the facts.
