A blocked drain in a leased shop, office or food premises is a different problem from a blocked drain at home — not technically, but contractually. Before anyone is called out, it is worth knowing who is entitled to arrange the work.
In an owner-occupied house, the person with the problem is the person who fixes it. In tenanted or commercial premises, those can be three different parties: the occupier who discovered it, the owner who holds the asset, and the managing agent who sits between them. What the lease says about maintenance and repairs usually determines who arranges the work and who carries the cost.
The practical consequence is that acting fast and acting correctly can pull in opposite directions. Commissioning a plumber directly gets the drain running today; it may also mean paying for something the lease made someone else’s responsibility. Reporting it and waiting preserves the position but leaves the drain blocked.
A workable rule for most situations: if there is an immediate health or safety issue — waste water surfacing where people walk, a food premises unable to operate hygienically — deal with the immediate risk and notify in parallel. If it is a slow drain that is a nuisance rather than a hazard, notify first and let the process work.
Food premises carry an additional dimension. Kitchens produce fats, oils and grease at a volume no domestic sink approaches, which is why commercial kitchens have arrangements for handling them that houses do not. A recurring blockage on a food premises line frequently traces back to how those are working, and that is a maintenance question rather than an emergency one.
None of this changes what is physically wrong with the pipe. It changes who makes the decision about it, and that is worth establishing before the call rather than during it.
One call, one conversation. Describe what the fixtures are doing and it usually narrows down quickly.

Maintenance and repair obligations are usually set out explicitly. It is the document that answers who arranges the work.
Even where you act immediately, a written record of when you reported it and what you did protects everyone.
Waste water where people walk, or a food premises that cannot operate safely, is urgent. A slow floor waste generally is not.
The same test applies here as anywhere: how many fixtures are affected, and is anything surfacing outside.
The detail lives on the service pages rather than being repeated here. These two cover the method side; the three below them cover the problem side.
A water-jetting method that cuts through a blockage and scours build-up off the pipe wall rather than only punching an opening through it.
Relevant when a drain blocks repeatedly, or grease, sediment or root matter is lining the pipe.
A camera survey that shows the inside of the pipe so the blockage can be located and the pipe condition assessed before any repair decision.
Relevant when a drain keeps blocking, when pipe damage is suspected, or before authorising repair work.
Main-line wastewater blockages, where several fixtures back up at once or an overflow relief gully starts discharging outside.
Rainwater drainage problems — surcharging pits, overflowing downpipes and pooling in the yard during or straight after heavy rain.
Fixture-level toilet blockages, and the signs that separate a pan or branch problem from a blockage further down the main drain.
Or start from the blocked drain services hub if you are not sure which one applies.
It is usually set by the lease or tenancy agreement, which typically distinguishes between damage or misuse by the occupier and maintenance of the property itself. Because the answer comes from the agreement rather than from plumbing, the practical step is to check what it says and to notify the owner or managing agent, while dealing separately and immediately with anything that is an actual health or safety risk.
Volume. A commercial kitchen puts far more fat, oil and food waste through its drains than a household does, and those substances leave the sink warm and liquid before cooling and setting on the pipe wall further along. That is why commercial premises have specific arrangements for capturing them, and why a recurring blockage on a food premises line is often a question about how those arrangements are being maintained.
