Drain Cleaning and Maintenance Services in the UK

Drains and sewers are vital links in our homes and businesses, ensuring wastewater is removed quickly and efficiently from the property and transported to a treatment facility. Typically this process is out of sight and out of mind, but when a drain or sewer blockage occurs, it requires immediate attention to prevent foul odours, flooding, and associated hygiene risks.

Whether it's emergency work to clear a blockage or the installation and maintenance of a kitchen drain system, keeping Britain's drain and sewer network flowing freely is dirty, but essential work.

Why Regular Drain Maintenance Matters

With a growing population resulting in additional strain on water companies and infrastructure, and an ever increasing focus on environmental impact, maintaining clean, free flowing drains has never been so important.

Making sure your drains are kept clear and clean is vital for:

Preventing costly blockages and flooding: Blocked drains need clearing quickly to not only get the system back ‘online’, but also to prevent flooding and possible exposure to hygiene hazards. Quickly clearing the blockage means the rest of the system can flow uninhibited, and potentially save thousands in clean up costs.

Reducing foul odours and hygiene risks: Whenever organic waste gathers within pipework, bacteria will thrive, odours will build up, and the risk of illness will rise. Foul smells, along with airborne bacteria will quickly be released into the building where pipework is not maintained or faulty traps and seals exist. Regular maintenance not only helps avoid complete blockages, it also eliminates the waste and bacteria within pipework that lead to smelly drains.

Protecting pipework and infrastructure: By looking after the inside of your drains, you help to prevent leaks and bursts which can result from partial blockages and the increased pressure placed on the system. Free flowing drains mean that pipework does not need to be regularly taken apart to remove clogs and blockages, and it also helps prevent those dreaded ‘fatbergs’ from forming further down the system.

Maintaining compliance with environmental standards and legal requirements: It’s a criminal offence under section 111 of The Water Industry Act 1991 to release anything into the public sewers that could interfere with the free flow of wastewater. A well maintained drain system means waste goes to the correct final destination for treatment. By keeping everything going where it should, the use of harsh chemicals is avoided and waste doesn't end up where it shouldn’t be.

Keeping businesses operating safely and smoothly: The last thing a busy commercial kitchen, head office building or retail venue needs, is a backed up drain or blocked toilet. By ensuring drains are well kept, and dealing with blockages rapidly if they occur, unnecessary costs for cleaning, and unneeded downtime are avoided.

Our Drain Cleaning Services

Our professional drain cleaning services include:

High pressure jetting

With no harmful chemicals or damaging mechanical equipment, high pressure jetting is a simple but extremely effective way of moving a blockage or cleaning internal areas of a drain. Our teams of drain cleaning experts use powerful, professional pressure cleaning equipment to quickly move even the most stubborn of obstacles.

Clogged drain cleaning services for kitchens, washrooms, and industrial systems

No matter the blockage or clog, we are equipped with specialist cleaning equipment to remove, clean and restore drains in your premises 24/7.

Sewer cleaning and descaling to remove grease, silt, and debris

Once grease and dirt start to accumulate in sewerage systems, they can rapidly build up and start to constrict the inside of the pipes. Regular and one off sewer cleans keep sewage moving, and prevent damage to pipework occurring over time.

CCTV drain inspections to identify problems early

Drains are, by nature, difficult to inspect. When they occur, blockages are often several feet from the surface. In this instance, specialised CCTV camera inspections to find blockages or damage to pipework are often the quickest way to get to the root cause of the problem, and save hours of wasted time searching.

Preventative maintenance plans for long-term drain health

Some drains are more problematic than others. Whether it's down to the location, the age or the design, some block and flood more often than the norm. Where this is the case, regular maintenance and preventative cleans are a fantastic way to prevent blockages from building gradually over time, and avoid more costly issues in the future.

Kitchen drains

Fats, oils and grease (collectively referred to as F.O.G) can quickly block kitchen drains. Under the Building Regulations Part H 2002, if you serve hot food then you must have a grease separator in your kitchen. Grease traps or separators, collect grease from waste water to prevent it entering the sewerage system. By introducing biological enzymes and ‘good’ bacteria’ to break down the F.O.G is reduces the need for more drastic measures to unblock drains, and provides round the clock maintenance of your commercial kitchen drainage system.

Rentokil Specialist Hygiene’s biological dosing service continually feeds your commercial kitchen drains and grease traps with a biological solution of harmless bacteria and enzymes, breaking down and dissolving contaminants in your pipework, preventing build-up and blockage problems from occurring.

Emergency Drain Unblocking

In an ideal world, any blocked drains would only happen in the middle of the week, at a time of day that's convenient to attend and address the issue. As is often the case however, drains often require attention quickly in the middle of the night. Our emergency teams are available 24/7 across the UK. We’ll identify and clear the problem quickly and safely to prevent disruption and damage.

Frequently Asked Questions


  • How much does it cost to get your drain cleared?

    Every blockage or clean is different. From a minor flush through to monster fatbergs. We provide a free, no-obligation survey and quote for all drain cleaning emergencies based on your requirements.


  • How do you professionally clean a drain?

    Our expert technicians use a range of specialised equipment and techniques to clean drains. We will always work according to COSHH guidelines and remove any waste generated from site.


  • How often should commercial drains be cleaned?

    As an average, commercial drains should be cleaned through at least every 6 months, but this can vary depending on the condition of the drain, and what's being put down it.


  • Can you clean a commercial drain with off the shelf drain products?

    You can, but it’s not ideal. As well as not always being very effective (domestic products are designed for use in domestic drains), it's often not required, and just adds to the growing levels of pollutants in our waterways.
