Drain unblocking from £175 

Our expert drainage engineers are trained in sorting a wide range of blocked drains, from blocked outside drains to a clogged kitchen sink. If you need your drain unblocking, we’re here to help.

Which blocked drain problems can we help with?

Our drainage engineers can help with the following blocked drain problems: 

Blocked outside drain (foul drains)

If you notice your outside drain overflowing or a persistent bad smell, your outside drain could be blocked. We’ll inspect the drain and remove any blockages to foul drains and outside drainpipes leading to sewers.

Blocked waste pipes

Deep blockages in your home’s waste pipes can be hard to shift. Our engineers can use a CCTV drain survey where necessary to find the source of a waste pipe blockage and remove it.

Blocked shower drain

Have a slow-draining shower? If home DIY methods have failed, our expert team of plumbers will find the blockage and remove it from your shower drains to get the water flowing again. 

Blocked toilets and sinks

Blocked toilets and sinks are a doddle for our plumbers. For when the plunger stops working, we’re available to sort the annoying blockages in your home.

What to expect from your blocked drain appointment

When you book a drain unblocking appointment from Ding you get the skills and expertise of HomeServe, who have been looking after the nation’s homes for more than 30 years. Here's what to expect from your appointment:

We're on our way

An expert plumber or drainage engineer will arrive at the time you booked. They’ll give you a call when they’re on their way. 

We'll assess the problem

The engineer will inspect the drain, sink or toilet to get to the bottom of the problem and they'll keep you informed of what's happening along the way.

We'll use the right tools for the job

If the blockage is in an outside drain or deep in the pipes, they may use a CCTV drain survey to find blockage. They’ll then use a drain auger and a high-pressure water jet to break it down.

We'll keep you in the loop

You’ll pay £175 for the first hour and, if it’s a bigger job or further parts are required, we’ll give you a quote for the work and make sure you’re happy with it before they continue.

Causes of blocked drains

If you have a good idea of what’s causing the blocked drain it can help us diagnose the problem quicker. If not, no worries – our drainage engineers will get to the bottom of it. Here are some common causes of blocked drains:

  • Leaves, litter, and outdoor gunk covering your outside drain

  • Kitchen culprits — fat, oil, coffee grounds

  • Bathroom build-up — hair, soap, wipes

Who’s responsible for blocked outside drains?

It all depends on where the blockage is.

Your drain, your fix — if the outside drain pipework is within your property boundary it’s often your responsibility. In this case you can book one of our expert drainage engineers.

Shared or public drains — these are your water company’s responsibility. Give them a call to see if they can help. Can’t remember who you’re with? Check your water bill.
