Tenancy Consents & Variations UK: Landlord Guide
We're not a law firm — we help you find the right legal support. For advice on your situation, speak to a legal adviser or find a solicitor.
During a residential tenancy, requests from tenants come up more often than most landlords expect. A tenant might ask to hang shelves, repaint the hallway, keep a rescue dog, or agree a small change to the rent day. Each of these situations sits outside the original tenancy agreement, and how a landlord responds can shape the rest of the letting.
Getting it wrong, whether by refusing unreasonably, agreeing verbally with no record, or altering terms in a way that is not enforceable, tends to create problems later. This guide is written for landlords in England who want to understand how consents, waivers and variations work in practice, what documentation helps, and where the common traps lie. It is general information rather than guidance on any particular tenancy.
What this document is
A consent or variation is a formal step that sits alongside the original tenancy agreement without replacing it. Consents grant permission for something the tenancy would otherwise prohibit or restrict, for example keeping a pet, making an alteration, or redecorating.
A waiver sets aside a particular term, either for a limited period or for the remainder of the tenancy. A variation is a mutual change to the agreed terms, which both landlord and tenant sign to confirm. Landlords may also issue regulations, meaning practical rules for the property such as bin days, communal area use, or noise expectations, where the tenancy reserves that right.
These tools exist because life in a rented home rarely stays still. Tenants start new jobs, grow families, take on pets and want to make a house feel like home. Landlords who document their responses in writing, with clear scope and any conditions attached, tend to avoid disputes about what was agreed, when, and on what terms. Verbal permission given at a viewing or over the phone has little evidential value if things go wrong.
How to use this document
- Receive the request in writing. Ask the tenant to set out what they are proposing, in enough detail that you can picture it. For alterations, that means what will be changed, where, and roughly how. For pets, the type, breed and number. A written request gives you something concrete to consider and refer back to.
- Consider the request against the tenancy. Read the existing agreement carefully. Some tenancies prohibit alterations outright, others require consent not to be unreasonably withheld. Pet clauses, redecoration clauses and clauses about running a business from home all vary. Your starting point is always what the tenant has already agreed to.
- Decide on conditions. Most consents come with reasonable conditions attached. For alterations, that often means reinstating the property at the end of the tenancy, using qualified tradespeople, or providing photographs. For pets, it might involve professional cleaning on departure. Set these out clearly so there is no later argument about what was expected.
- Record the decision in the right document. A letter of consent, waiver or variation agreement should identify the property, the parties, the tenancy it relates to, and the precise scope of what is being permitted or changed. Variations that change rent, term length or parties need particular care because they can have legal and tax consequences.
- Keep the paperwork with the tenancy file. Store the signed document alongside the original tenancy agreement, deposit protection paperwork and gas safety records. If the property is later sold or the tenancy assigned, the next landlord needs to see the full picture of what has been agreed over time.

Common questions
Q Do I have to agree to a tenant's request to keep a pet?
Not automatically, but the position has shifted in recent years. Many tenancies now include a clause requiring consent not to be unreasonably withheld, and the government has signalled a direction of travel towards stronger tenant rights around pets. In practice, refusing flatly without considering the specific animal and circumstances is risky. A conditional consent letter is often the sensible middle ground.
Q What is the difference between a waiver and a variation?
A waiver sets aside a particular term of the tenancy, often temporarily, without changing the underlying agreement. A variation formally amends the terms themselves, with both parties signing to confirm. Variations tend to be used for permanent changes such as rent adjustments or adding a new occupier, while waivers suit one-off situations like allowing late rent for a month.
Q Can I charge a fee for giving consent to alterations?
The Tenant Fees Act 2019 restricts what landlords can charge tenants during an assured shorthold tenancy in England. Certain permitted payments exist, but this is an area where getting it wrong can mean repayment and penalties. If you are thinking of charging for processing a consent request, take care to check whether any fee is lawful under the current rules before proceeding.
Q What happens if I give consent verbally and the tenant does more than I agreed?
Verbal consent is technically capable of being binding, but it is very hard to prove and almost always leads to arguments about scope. If a tenant strips wallpaper when you agreed to painting, or installs a cat flap when you agreed to keeping a pet, the evidential picture becomes messy. Writing it down, even in a short letter, protects both sides.
Q Does a variation need to be signed as a deed?
Most variations of residential tenancies can be made in writing signed by both parties, without needing the formality of a deed. However, where the change affects the length of the term, creates a new interest in land, or involves a guarantor, the position becomes more technical. If the variation is significant, it is worth getting it checked before signing.
Q Can I impose new rules on the property mid-tenancy?
Only if the tenancy reserves the right for you to make regulations, and only where those regulations are reasonable. You cannot use house rules to introduce new obligations that effectively change the tenancy itself. Typical examples include communal cleaning rotas or parking arrangements, rather than anything that alters rent, term or core tenant rights.
Q What if the tenant refuses to sign a variation I want to make?
A variation requires agreement from both sides. If the tenant will not sign, you cannot force the change during the fixed term. Your options are usually to negotiate, to wait until the tenancy reaches a point where a new agreement can be offered, or in some cases to follow the statutory route for rent increases. Unilateral changes risk being unenforceable.
