Fast, reliable drain unblocking and jetting services for businesses and industrial sites throughout the UK

Professional Drain Unblocking & Cleaning for Commercial and Industrial Sites

A blocked drain on a commercial or industrial site is far more than an inconvenience — it can disrupt operations, create health and safety risks, and in serious cases force a full site shutdown. Drain Alert provides a comprehensive commercial drain unblocking and cleaning service, available every day of the year, to keep your drainage systems functioning and your business protected.

Our satellite-tracked response fleet is fully equipped to handle everything from routine blockages to complex drainage failures. With no call-out charges, fixed pricing, and a free on-site assessment, you will always know exactly what to expect before any work begins.

No call-out charges. Fixed prices. Free on-site assessment. Available 365 days a year.

Why Drain Maintenance Matters for Your Business

Regular drain cleaning is one of the most cost-effective forms of preventative maintenance a commercial or industrial site can invest in. Blocked or poorly maintained drainage systems can lead to:

  • Operational disruption: A severe blockage can halt production lines, close facilities, or render areas of your site unusable
  • Flooding: Blocked drains are a leading cause of internal and external flooding on commercial premises
  • Health and safety risks: Standing water, sewage overflow, and drainage failure can create serious hazards for staff, visitors, and the public
  • Regulatory exposure: Poorly maintained drainage can result in compliance failures, particularly in food production, manufacturing, and industrial environments
  • Costly reactive repairs: Addressing a severe blockage or drain failure always costs significantly more than routine preventative maintenance

Drain Alert works with a wide range of commercial clients — including local authorities, schools and colleges, manufacturing facilities, retail sites, and industrial operators — to ensure drainage systems remain clear, compliant, and fully functional throughout the year.

Common Causes of Blocked Drains

Commercial and industrial drain blockages can arise from a wide variety of sources. Common causes include:

  • Fats, oils, and grease (FOG): Particularly prevalent in commercial kitchens, food manufacturing, and hospitality venues — accumulations solidify inside pipework over time
  • Industrial process waste: Residue and sediment from manufacturing or processing operations can build up in drainage systems
  • Silt and debris: Leaves, grit, and silt in external drains and manholes are a frequent cause of slow drainage and blockages
  • Tree root ingress: Roots from nearby trees can penetrate and crack drainage pipes, causing partial or complete blockages
  • Foreign objects: Items incorrectly disposed of via toilets or sinks — including wipes, sanitary products, and packaging — are a common source of blockages in commercial premises
  • Scale and deposit build-up: Limescale and mineral deposits accumulate on the internal walls of pipes, gradually reducing flow capacity

How We Clear Blocked Drains

All Drain Alert response vehicles are fully equipped with a comprehensive range of drain clearing and cleaning equipment, enabling our engineers to tackle blockages of any scale effectively and efficiently.

High-pressure water jetting

Our primary method for clearing and cleaning larger commercial drains, manholes, and sewer pipes — high-pressure jetting removes blockages, strips away scale, and leaves pipework thoroughly clean

Electro-mechanical cable equipment

Used for sinks, toilets, and smaller-diameter pipework, our spiral cable systems clear even the most stubborn internal blockages

Root cutting attachments

Specialist jetting nozzles and cutting heads for clearing tree root ingress without the need for excavation

Confined space equipment

Where required, our teams are equipped and trained to work safely in confined drainage environments

Following any unblocking or cleaning work, we carry out a final check to confirm the drain is running freely. Where we identify evidence of structural damage or further issues, we will advise you accordingly — and our CCTV Drain Survey service is available to provide a full diagnosis.
