How Much Does Drain Cleaning Cost? What a Planned Clean Includes

What drain cleaning costs depends on how many runs and chambers are cleaned, what has built up inside the pipes and whether a camera check is part of the job. A planned clean of a short domestic run with clear access, booked in standard hours, sits at the lower end. A clean that has to cut through scale, grease or roots, or covers several runs and chambers, costs more. Our figures are set by job type and time band on the published rate card. This guide covers what a planned drain clean includes, what drives the price and when it is not worth paying for at all.

What does drain cleaning include?

A proper drain clean removes the deposits lining the pipe, not just a single blockage. That normally means jetting the runs, cleaning out the inspection chambers and checking the result.

Depending on what is in the pipe, the work can include:

• Rodding to break up a soft build-up or a partial blockage.
• High-pressure jetting to scour grease, silt and soft deposits from the pipe wall.
• Descaling with mechanical cutting heads where hard scale or calcified deposits have narrowed the bore.
• Chamber cleaning, clearing the benching and channels in each inspection chamber so waste does not catch there.
• A camera check before or after, to confirm the pipe is clean and to spot damage.

A quote that just says "drain cleaning" could mean any combination of these. Ask which ones are included.

Is drain cleaning the same as drain unblocking?

No. Unblocking is reactive: a drain has stopped and needs clearing now. Cleaning is planned: the drain still runs, and the aim is to remove build-up before it causes a blockage.

That difference affects the price. A planned clean can be booked in standard hours, at a time that suits you, so it avoids evening and night rates. An unblocking often happens at the worst possible moment and is priced accordingly. The work itself can look similar, since both often use a jetter, but a clean usually covers more of the system than a single blockage clearance. For how the jetting element is priced on its own, see our guide to how much drain jetting costs.

What sets the price of a drain clean?

The length of pipe, the number of chambers, what the deposit is made of and how easy the site is to work on. Everything else is detail.

• Runs and chambers. A single run from a kitchen to one chamber is a small job. A house with a rear extension, a side return and three chambers is a bigger one.
• Type of deposit. Soft silt and grease come out with jetting. Hard scale and old grease that has set need descaling, which is slower.
• Roots. Fine roots can be cut during a clean, but roots are a sign the pipe has an opening, so they tend to come back.
• Access. Chambers that are easy to lift, a van close to the property and room to run hoses keep the job short. Parking restrictions and long hose runs through a house add time.
• Waste removal. Most domestic cleans wash debris downstream. Large amounts of silt or grease may need collecting and disposing of by a licensed carrier.
• Time band. A planned clean should never need an out-of-hours rate. If a quote includes one, ask why.

Should a CCTV check be part of the price?

For a planned clean, a short camera check is worth having, because it is the only way to see whether the pipe is actually clean and in sound condition. It adds to the cost, so decide whether you need it before you compare quotes.

A camera check tells you two things: whether the clean worked and whether there is a defect, such as a displaced joint or a crack, that will keep catching waste. If there is, cleaning more often will not fix it. A quick check at the end of a clean is not the same as a full survey with a coded written report. That is a separate job, priced separately, and is usually only needed when you are buying a property, making an insurance claim or planning a repair.

When is paying for drain cleaning a waste of money?

When the drains are running well and have no history of problems. Most houses do not need their drains cleaned on a schedule, and paying for a clean "just in case" rarely makes sense.

Drain cleaning is also the wrong answer in these cases:

• The problem is inside the house. A slow basin or shower is often a blocked trap or waste pipe, not the underground drain. That is a smaller, cheaper job.
• The pipe is damaged. If a drain keeps blocking in the same place, a camera is more useful than another clean. Cleaning a broken pipe treats the symptom.
• It is a public sewer. If the blockage is in a sewer shared with neighbours beyond your boundary, it is usually the water company's to clear, not yours to pay for.

A planned clean does make sense for a house that has blocked more than once, a property with old clay drains and a history of silt, or before a new tenancy or sale when you want to know the drains are in order.

How often does a house need its drains cleaned?

Most houses only need a clean when there is a sign of trouble: slow drainage, gurgling, smells or a blockage. There is no standard interval for domestic drains.

If you have had repeat blockages, a clean followed by a camera check tells you whether it was build-up or a defect. If it was build-up, the cause is usually what goes down the drain, most often fat, wipes or food waste, and changing that saves more than any schedule. Businesses are different, because kitchens, gyms and busy washrooms load their drains far faster. Our guide on how often commercial drains should be cleaned covers setting a schedule for a business.

How do you compare drain cleaning quotes?

Make sure each quote covers the same runs, the same methods and the same check at the end. Then compare the totals.

Ask each company: which runs and chambers are included? Is it jetting only, or descaling where needed? Is a camera check included, and will I see the footage? Is VAT included? What happens if the engineer finds damage? A company that answers those in writing before the visit is one whose invoice will match its quote.
