A blocked drain in Manchester is usually a back yard gully that will not take the rain, a cellar that smells after a downpour, or a shared house where four people put wipes down one toilet. Tell us the problem and the postcode. We pass that to local drainage companies that cover it.

Common signs of a blocked drain in Manchester

• The toilet fills and drops slowly, or does not clear at all
• Grey water rising in the shower when the washing machine empties
• The gully in the back yard standing full after rain
• More than one sink going slow at the same time
• A drain smell in the cellar, which is where a Victorian terrace shows the problem first
• Water coming up between the flags in the yard rather than going down

Once the pipe is restricted it almost never frees itself. Wipes, fat and silt build on whatever is already stuck, and the run closes over weeks rather than in one go.

What people typically pay in Manchester (2026)

Some Manchester firms advertise from around £60 for a simple daytime job. Treat that as a starting point. Access in a terraced back yard, a drain cover buried under the flags, a long run in a mill conversion, or an out of hours visit puts the price up.

National ranges sit on what drain unblocking costs. A local camera guide sits on CCTV drain survey Manchester.

The North West blocks 22,000 times a year

United Utilities puts a number on it. Across its region there are 22,000 sewer blockages a year and 7,000 incidents of sewer flooding to homes and gardens.

The second figure is the important one. Seven thousand times a year, in the North West alone, waste comes back into somebody’s house or garden rather than leaving it.

Their advice is blunt and it is the right advice. Only flush the three Ps: pee, poo and toilet paper. Everything else, wipes included and especially the ones sold as flushable, goes in the bin. Fat and cooking oil go in the bin too, not down the sink.

A domestic blockage is that same material at a smaller scale. Wipes catch on a joint, fat sets around them, and the pipe narrows until the day it closes.

Boxing Day 2015 was a river, not your drain

Greater Manchester still measures flooding against Boxing Day 2015. The official investigation recorded over 2,200 properties flooded internally across 65 communities in eight local authority districts, with another 2,450 saved by defences and around 31,200 losing power.

The worst clusters were Lower Broughton in Salford with 750 properties, Radcliffe and Redvales in Bury with 670, and Littleborough and Rochdale with 175. Up to 128mm of rain fell in 36 hours on already saturated ground, which the report put at a one in fifty to one in a hundred year event.

More than 80% of that internal flooding came from main rivers, the Irwell, the Roch, the Croal and the brooks feeding them. Not from blocked drains.

That distinction matters when you are standing in water. River flooding is an Environment Agency and council matter. A blocked gully in your own yard is a job for a drainage company. A sewer running full is United Utilities. Three different problems, and the right call is different for each one.

If water is rising outside and it is raining hard, that is not a job for rods. If your yard gully is full on a dry day, it is.

Cellars in the Victorian terraces

Rusholme, Levenshulme, Gorton, Moss Side, Longsight and Openshaw are terraced, and a great many of those houses have cellars.

A cellar is below the level of the drain. When the run under the yard restricts, or the sewer in the street is full, the cellar is the lowest opening in the house, so the water reaches it first.

• A drain smell in the cellar is often the earliest warning you get, before anything upstairs is slow
• Damp on the cellar wall near the front can be a cracked drain rather than rising damp, and the two get confused constantly
• If waste appears in the cellar, that is an emergency call rather than something to watch

This is a good reason to have a camera down the run before you spend money on tanking a cellar. A survey is cheaper than damp proofing the wrong problem.

Back yards, shared entries and buried covers

The classic Manchester terrace has a small flagged yard, a back gate and an entry running behind the row. The drain cover is often under those flags, sometimes concreted over by a previous owner.

Two things follow, and both show up on the invoice.

• Access. A jetting hose has to reach the cover. If the van cannot get down the entry, the hose runs through the house or over the yard wall
• Finding the cover. If it has been paved over, someone has to locate it before any work starts, and that is time on the clock

The student belt: Fallowfield, Withington and Rusholme

Manchester has a very large student population, and it is heavily concentrated in a few areas. Fallowfield, Withington, Rusholme and Ladybarn are dense with shared houses.

A three bedroom terrace built for one family now holds five or six people who have never had a conversation about what goes down the toilet. Wipes, cooking fat, cotton buds and the occasional tea towel all meet in one pipe under the yard.

Mill conversions and city centre apartments

Ancoats, the Northern Quarter, Castlefield and New Islington are full of converted mills and warehouses, and newer blocks alongside them.

The drainage in a conversion is rarely original. It is new pipework threaded through an old building, often with long horizontal runs to reach an existing connection, and sometimes with pumps where there is no fall.

• Long shallow runs block more easily than short steep ones, because there is less push behind the water
• A pumped system that fails is an immediate problem, not a slow one
• The stack is shared, so a neighbour’s habits become your blockage

In a block, tell the building manager or managing agent before you instruct anyone. Communal pipework is usually a service charge matter, and a bill you paid yourself can be hard to recover afterwards.

Who looks after the drain in Manchester

• You, or your landlord. Everything inside the house, and the pipe outside that serves only your house up to the boundary or up to the join with shared pipework. Manchester City Council sets out the position on drainage on private property
• United Utilities. The public sewer beyond the boundary, and most shared pipes serving two or more properties. Their guide to sewers and drains explained shows where the line falls. A blockage on their network is cleared at no charge
• Manchester City Council. Road gullies and highway drainage. Standing water in the street, a missing grid or a blocked road drain goes to them through road obstructions, floods and drains
• The freeholder or managing agent. In an apartment block or a mill conversion, the shared stack and communal runs, normally through the service charge

From 1 October 2011 most private sewers and lateral drains in England transferred to the water company. In a terraced street where several houses share a run behind the row, that usually means United Utilities rather than the householders, which is worth knowing before anyone starts splitting a bill four ways.

The quick test before you ring anyone

• Only your house affected, dry weather. Private pipework, so a contractor
• Several houses in the row at once. Likely the shared run or the sewer, so United Utilities
• Only in heavy rain, and it clears afterwards. The network under load rather than a blockage
• Water in the road, not the house. The council

FAQs in Manchester

My cellar smells of drains. Is that serious?

It is worth acting on. A drain smell in a cellar often means a cracked or restricted run under the yard, and cellars are the lowest opening so they show it first. A camera survey will tell you whether it is a blockage or a broken pipe.

Is this because of the Boxing Day floods?

Almost certainly not. That was river flooding, over 80% of it from the Irwell, the Roch, the Croal and their brooks. A blocked drain in a back yard is a different problem with a different fix.

Is a CCTV survey worth it on a terrace with a cellar?

Yes. Old clay runs under a flagged yard, a cellar below drain level and possible damp all point the same way, and a survey is cheaper than guessing.

I live in a mill conversion and the kitchen is slow. Who do I tell?

The building manager or managing agent first. The stack and communal runs are usually theirs, and instructing your own contractor for a shared pipe can leave you with the bill.

How quickly can someone attend?

Same day and next day cover is normal across the M postcodes. Emergency rates apply out of hours. If waste is coming into the house or the cellar, ring as well as filling in the form.
