How much does high-pressure drain jetting cost?

Most drain jetting jobs cost between £150 and £300, depending on the severity of the blockage and the size of the drainage system. We quote fixed prices before starting - no hourly rates, no surprises. Simple blockages in accessible drains are at the lower end. More complex jobs involving long pipe runs, heavy root ingress, or commercial systems cost more.

What is high-pressure drain jetting?

High-pressure drain jetting uses a powerful jet of water - typically between 3,000 and 4,000 PSI - to blast away blockages and clean the inside of your pipes. A flexible hose with a specialised nozzle is fed into the drain, and the water jet breaks up obstructions while scouring the pipe walls clean. It's more thorough than rodding and doesn't use any chemicals.

What can drain jetting remove?

Drain jetting effectively removes grease, fat, and oil buildup, tree roots that have grown into pipes, limescale and mineral deposits, food waste and organic matter, soap scum and hair, silt, mud, and debris, and even some types of concrete orite buildup. The high-pressure water can cut through most obstructions that cause blockages.

Is drain jetting better than drain rodding?

For stubborn or recurring blockages, yes. Rodding pushes or pulls a tool through the blockage to create a channel. Jetting blasts the entire blockage away and cleans the full width of the pipe. If you've had a blockage cleared by rodding and it's come back within weeks, jetting will provide a more thorough and longer-lasting solution.

Can drain jetting damage my pipes?

When done properly by experienced engineers, drain jetting is safe for most pipe types. We assess the condition of your pipes before jetting and adjust the pressure accordingly. Older clay pipes or pipes that are already damaged may need lower pressure or a different approach - we'll advise you before starting any work.

How long does drain jetting take?

Most residential drain jetting jobs take between 30 minutes and 2 hours, depending on the length of pipe and severity of the blockage. Commercial systems with longer pipe runs or heavier buildup may take longer. We'll give you a realistic timeframe once we've inspected the drain.

Do you inspect the drain before jetting?

Yes. We include a CCTV drain inspection before jetting to see exactly what's causing the problem. This lets us confirm jetting is the right approach, select the correct nozzle, and check for any pipe damage that might affect how we proceed. You'll see the footage and understand what we're dealing with before we quote.

Can drain jetting clear tree roots?

Yes. We use specialised cutting nozzles that can slice through tree roots that have grown into your pipes. Jetting removes the roots and clears the debris. However, if roots have caused significant pipe damage, you may need repairs to prevent them growing back. We'll identify this during our CCTV inspection and explain your options.

Is drain jetting safe for the environment?

Yes. Drain jetting uses only water - no chemicals, acids, or caustic substances. The high-pressure water does the work, making it one of the most environmentally friendly ways to clear and clean drains. It's safe for your pipes and won't harm the local water system.

Can you jet indoor drains as well as outdoor?

Yes. High-pressure jetting works on indoor drains (kitchen sinks, bathroom drains, internal waste pipes) and outdoor drains (manholes, gullies, main drains, storm drains). We use appropriate pressure levels and nozzles for different pipe sizes and locations.

When should I use jetting instead of other methods?

Jetting is the best choice when blockages keep coming back after rodding, the blockage is caused by grease, fat, or heavy buildup, tree roots are growing into your pipes, limescale is narrowing your pipes, you want preventative cleaning to avoid future blockages, or drains need clearing before a CCTV survey or repair. For simple, one-off blockages close to the surface, rodding may be sufficient and more cost-effective.

Reliable service when you need it most

Some blockages won't shift with rodding or chemicals. Grease that's been building for months, tree roots that have grown into your pipes, or years of limescale narrowing your drains - these need something more powerful.

The right tool for tough blockages

Our van-mounted jetting units deliver water at pressures up to 4,000 PSI - enough to cut through the most stubborn obstructions. Different nozzle attachments let us tackle everything from grease buildup to invasive tree roots.

Thorough cleaning, not just unblocking

Rodding punches a hole through a blockage. Jetting scours the entire pipe wall, removing buildup that would otherwise cause problems again in weeks or months. It's the difference between a quick fix and a proper solution.
