Call Let’s Fix Group Ltd and we will tell you whose drain it is before we lift a lid.

Do councils unblock drains?

Councils will unblock drains they are responsible for, which in practice means road gullies and surface water drainage on the public highway. They do not clear the drains inside your property boundary or the pipes serving your home, so a blockage in your own drain remains a private job for a drainage engineer.

The line between a public drain and your own

The confusion nearly always comes down to ownership. Anything from your sinks, toilets, baths and rainwater downpipes runs through your own drainage until it reaches the boundary of your property. That length is yours to maintain. Past the boundary, the pipe usually becomes a lateral drain or a public sewer, and that sits with the local water and sewerage company rather than the council.

The council’s slice is narrower than most people assume. Highway drainage, the grilles at the kerb, ditches and culverts along adopted roads: that is council territory, and if a road gully is flooding the street outside your house, the council highways team is the right call. If the water is backing up out of a gully in your own driveway, a chamber in the back garden, or an outside toilet, no council crew is coming for it.

That matters because a blocked drain rarely waits. Sewage lifting a manhole lid or a toilet that will not clear is a same-day problem, and passing it to the wrong body burns the hours you do not have. Whether you need drain unblocking or a blocked drain in High Wycombe seen to, we cover the whole area, and there are expert drainage engineers based across the region who can get to the property quickly.

What actually happens when you report a drain to the council

Reporting a highway drain to a council goes into a queue. It gets logged, assessed, prioritised against everything else on the network, and scheduled with the gully cleansing contract. For a slow-draining road gully that is perfectly reasonable. For anything urgent inside a boundary it is the wrong route entirely, and the response you get back will simply tell you the drain is private.

Water companies work the same way for lateral drains and public sewers. They will attend, and they will clear a blockage on their asset, but the first thing their operative does is establish where the blockage sits. If it turns out to be on your side of the boundary, you are back at the start, having lost a day or more. That is why the practical order of events is usually to get the drain investigated first, then let the evidence decide who pays.

Camera work settles it quickly. A CCTV inspection down the run shows the blockage, its distance from the chamber and whether it falls inside or outside the boundary. Whether you need drain unblocking or drain unblocking in Luton, we cover the whole area, and every job starts with finding out what is actually wrong rather than guessing.

How a private drain blockage gets cleared properly

Most private blockages come down to a handful of causes: fat and grease hardening in a kitchen run, wipes and sanitary items in a soil pipe, root ingress at a joint, silt building up in a shallow gully, or a collapsed or displaced section that keeps catching debris. The cause dictates the method, which is why simply forcing a rod through and walking away tends to buy a few weeks rather than fix anything.

David Prince heads a team of expert drainage engineers working across Greater London and the South East, all of them the firm’s own people rather than subcontracted labour. The kit is chosen to match the fault: high-pressure jetting for grease and silt, mechanical rodding where jetting is not appropriate, CCTV for inspection and proof, and acoustic or sonar tracing to locate a buried run before anyone lifts a slab. Non-invasive diagnostics come first, so digging is a last resort rather than an opening move.

Around nine in ten repairs are finished the same day, and pricing is fixed and explained before work starts, so there is no surprise attached to the visit. If the camera shows a broken pipe rather than a simple obstruction, the same team handles drain repair and relining as well as clearing, so you are not chasing a second firm for the follow-up. Full details of how we approach a blocked drain sit on our drainage pages.

Typical signs it is your drain and not a public one:

• More than one appliance in the house draining slowly at the same time
• Water rising in an inspection chamber inside your boundary
• Gurgling from a toilet or bath when another outlet is used
• A drain smell around gullies, downpipes or an outside gully grid
• Standing water on a patio or driveway after rain that never clears

Where responsibility gets shared and what to do about it

Shared drainage complicates things again. Terraces, flats and older estates often have one run serving several properties, and a blockage in that shared length is a shared responsibility rather than one household’s problem. In practice, whoever notices it first tends to sort it, then recovers a share afterwards. Leasehold flats are usually covered by the managing agent or freeholder for anything outside the individual dwelling, so it is worth checking the lease before you pay anyone.

Either way, a documented inspection is the thing that protects you. A recorded camera survey showing where the blockage is, and on which side of the boundary, is what a neighbour, a managing agent, a water company or an insurer will actually act on. Guesswork gets argued with. Footage does not.

Our engineers cover drain unblocking, drain cleaning, CCTV surveys and drain repair, and also handle installation work where a new run, gully or soakaway is needed. Fully insured, tidy on site, and the property is left as it was found. Send us a picture of what you are seeing and one of the team can usually tell you straight away whether it is a council matter, a water company matter or one for us.
