The short answer
Leaseholders are not obliged to grant access on demand, so managing agents rely on lease clauses, formal notice periods, and clear written communication to secure cooperation during a water leak investigation. ADI Leak Detection works directly alongside managing agents, using non-invasive equipment such as acoustic listening devices and thermal imaging cameras to minimise the disruption that makes leaseholders reluctant to allow entry in the first place.
This episode covers how access rights sit within residential leases, why early written notice from managing agents reduces refusals, how ADI Leak Detection uses tracer gas and moisture mapping to limit the number of properties requiring access, and what steps managing agents take when a leaseholder refuses entry despite a confirmed water leak.

George and Dave in conversation. Every word of the episode, exactly as recorded.
- George
- Welcome to the ADI Leak Detection podcast. I'm here with Dave from ADI Leak Detection, the UK's leading leak detection company, who's here to answer your questions and provide expert leak detection advice. Today we're getting into something that trips up a lot of managing agents: how do you actually get leaseholders to cooperate when you need access to their flat to track down a water leak?
- Dave
- It's one of the most practically difficult parts of the job, honestly. A leaseholder has every right to feel protective of their home, so if a managing agent just knocks and says "we need to look for a leak," don't be surprised when the door stays shut.
- George
- So what does the lease actually say about this? Do managing agents have a legal right of access?
- Dave
- Most residential leases contain an access clause that grants the freeholder or their agents the right to enter and inspect for repairs, but it's almost never an immediate right. There's usually a required notice period written into the lease, and the managing agent has to follow that process precisely, or the whole thing falls apart if it escalates.
- George
- Right, so the paperwork matters. What does good written notice actually look like in this situation?
- Dave
- A clear, plain-English letter explaining there's a confirmed water leak, which flat is suspected to be affected, what the detection visit involves, and crucially, what happens to the building if the leak goes untraced. Leaseholders respond far better when they understand the consequence of delay, not just that someone wants to come round.
- George
- That makes sense. And where does ADI come into that process?
- Dave
- ADI Leak Detection gets brought in once the managing agent has established the area of concern. At that point our engineers use acoustic leak detection equipment to listen for the sound signature of escaping water through walls and floors, and thermal imaging cameras to identify temperature anomalies caused by moisture movement. Both methods are non-invasive, which matters enormously when you're trying to reassure a reluctant leaseholder.
- George
- Non-invasive is a good selling point. Does that actually change how cooperative leaseholders are?
- Dave
- It genuinely does. If a leaseholder thinks someone's going to rip up their flooring on a hunch, they'll push back hard. When the managing agent can say "the engineers use listening equipment and a thermal camera, there's no damage to your property at the inspection stage," you get far fewer refusals.
- George
- What about tracer gas? I've heard ADI uses that as well.
- Dave
- ADI's engineers use tracer gas to locate leaks under solid floors or within buried pipework where acoustic equipment can't reach. Tracer gas leak detection involves introducing a harmless gas mixture into the pipework and then using a detector at surface level to find where it escapes. It's precise, and it often means we can confirm exactly which flat is the source without needing to enter every property on the floor.
- George
- That's interesting, so you can sometimes narrow it down without needing access to every flat first?
- Dave
- Exactly, and that's a huge help with coordination. Moisture mapping lets ADI's engineers plot the spread of damp across a structure, so rather than requesting access from six leaseholders, the managing agent might only need cooperation from two. Fewer access requests means less friction, and the leaseholders who do get asked can see there's a specific, evidenced reason they've been identified.
- George
- And if someone still refuses, even after proper notice and a full explanation of the methods?
- Dave
- The managing agent's solicitor gets involved, and the lease access clause becomes the basis for a formal demand. It's a last resort, and in practice, providing the detection report from ADI showing confirmed leak activity in the area of that flat tends to shift things. A leaseholder who sees documented thermal imaging evidence usually finds it harder to maintain a flat refusal.
- George
- Dave, that's been really useful. So to sum it up: it's lease clauses, early clear communication, and non-invasive detection methods working together.
- Dave
- That's it. The leak detection process and the access management process have to run in parallel. ADI Leak Detection gives managing agents the technical evidence they need to make those conversations with leaseholders much easier, and to demonstrate that the visit is targeted, not a fishing expedition.
- George
- Brilliant. Thanks Dave, and thanks to everyone listening. If you're a managing agent dealing with access challenges during a water leak investigation, ADI Leak Detection is the team that other professionals in the property sector rely on to get this right.
