Whether it's a routine inspection, a contractor coming to fix the boiler, or a viewing for a new tenant, the same underlying rule applies: a tenant's home is legally their own space, and access is something you request, not something you're entitled to walk in and take. Here's how that plays out across the three situations landlords run into most.
The principle behind all of it. Tenants have a right to “quiet enjoyment” of their home, this isn't a courtesy, it's a long-standing legal protection. Even where your tenancy agreement includes a clause allowing access, that clause gives you the right to request entry, not the right to enter regardless of the tenant's answer. If a tenant says no, you cannot force your way in, whatever the reason for the visit.
What's required, in every case except a genuine emergency: at least 24 hours' written notice (email or text counts), a reasonable time of day, and the tenant's actual agreement, not just their failure to object.
Viewings (re-letting or sale). A tenant can refuse a specific date or time and propose an alternative, and you should try to accommodate it. They can also refuse any viewing where proper notice wasn't given. Since the Renters' Rights Act ended fixed terms and Section 21, there's no longer a natural “end of tenancy” window creating an obvious point for viewings to start. In practice, this means viewings are appropriate once a tenant has given their own notice to leave, or once a valid Section 8 ground is underway, not simply whenever it suits your marketing timeline.
Routine inspections. The same 24-hour notice and reasonable-time rules apply. A tenant refusing one specific inspection date isn't refusing inspections altogether, and treating it that way tends to escalate a scheduling issue into a genuine dispute.
Contractors and repairs. This is where refusal creates the most real risk, because some of what you need access for isn't optional on your side. An annual gas safety check is a legal duty under the Gas Safety (Installation and Use) Regulations 1998, not a preference, and it needs genuine access to complete. If a tenant is blocking a required safety check, document every notice and attempt in writing, that record matters both for your own compliance and if the situation needs to escalate. Genuine emergencies (a gas leak, a serious leak, anything posing immediate risk) are the one exception to the notice requirement, entry can be reasonable without 24 hours' notice where safety is at stake.
When it tips into a real problem. Persistent, unreasonable refusal of all access, with no attempt to cooperate or propose alternatives, is different from an occasional inconvenient date. Repeated, pressured, or badly-timed access requests can themselves amount to harassment under the Protection from Eviction Act 1977, so this cuts both ways. If access refusal is stopping you from meeting a legal safety obligation, that's worth professional advice rather than repeated informal requests. In our experience this is genuinely rare, most refusals resolve with a short, polite conversation and a bit of flexibility on timing, not a legal escalation.
