High-pressure water jetting is the most effective method for clearing stubborn drain blockages and restoring full flow. This guide explains what drain jetting costs in London, when it's the right solution, and what's included in the price.
Drain Jetting Prices

When Is Drain Jetting Needed?
Drain jetting uses high-pressure water (typically 3,000–4,000 PSI) to blast through blockages and clean pipe walls. It's the go-to solution when standard drain rodding isn't enough, or when a thorough clean is required.
- •Recurring blockages — drains that block repeatedly despite rodding
- •Heavy grease or fat build-up — common in kitchen drains and restaurants
- •Tree root intrusion — roots growing into pipe joints
- •Scale and mineral deposits — hard water residue narrowing pipe bore
- •Preventative maintenance — keeping drains clear before problems occur
- •Pre-purchase surveys — clearing and inspecting drains before buying a property
If you're unsure whether jetting is the right approach, our engineers will assess the situation on-site and recommend the most cost-effective solution. We often combine jetting with a CCTV drain survey to confirm the pipe is clear and check for any underlying damage.
What Affects Drain Jetting Costs?
The price of drain jetting varies based on several factors specific to your property and the blockage. Here's what influences the final quote:
Pipe Length & Diameter
Longer pipe runs and larger-diameter commercial drains require more time and water volume. A short residential run can be jetted in 30 minutes, while a long commercial line may take 2 hours or more.
Blockage Severity
A moderate grease build-up clears faster than a solid compacted blockage or extensive root intrusion. Severe blockages may require multiple passes with different jetting heads.
Access & Location
Easy access to a manhole or drain entry point keeps costs down. Restricted access — such as basement drains, drains beneath decking, or shared access in flats — may require additional set-up time.
Equipment Required
Standard jetting uses a van-mounted unit with sufficient pressure for most residential and commercial jobs. Larger or deeper drains may need a trailer-mounted unit with higher flow rates, which can increase the cost.
Jetting vs Other Drain Clearing Methods
Not every blockage needs jetting. Here's how the main drain clearing methods compare on cost and effectiveness:
| Method | Typical Cost | Best For | Limitations |
|---|---|---|---|
| Drain rodding | £80 – £150 | Simple, localised blockages | Limited reach, doesn't clean pipe walls |
| Electromechanical cleaning | £100 – £200 | Solid obstructions, root cutting | Doesn't flush debris from pipe |
| High-pressure jetting | £150 – £400 | Grease, roots, full pipe clean, maintenance | Higher cost, requires water supply access |
| Chemical treatments | £10 – £30 (DIY) | Minor slow-running drains | Ineffective on solid blockages, can damage pipes |

Frequently Asked Questions
How much does drain jetting cost in London?
Drain jetting in London typically costs between £150 and £400, depending on the length of pipe, severity of the blockage, and whether the drain is residential or commercial. A standard single-drain residential jetting starts from £150.
When is drain jetting needed instead of drain rodding?
Drain jetting is recommended for stubborn or recurring blockages, heavy grease or fat build-up, tree root intrusion, and for preventative maintenance cleaning. Rodding is effective for simpler, localised blockages, but jetting provides a more thorough clean across the full pipe length.
Is high-pressure drain jetting safe for old pipes?
Yes, professional drain jetting is safe for most pipe types, including older clay and cast iron pipes. Our engineers adjust the water pressure to suit the pipe material and condition. We always carry out a visual assessment first and can recommend a CCTV survey if there are concerns about pipe integrity.
How often should drains be jetted?
For residential properties, annual jetting is recommended for drains prone to grease or root intrusion. Commercial kitchens and restaurants in London should schedule jetting every 3 to 6 months to prevent grease blockages and comply with hygiene regulations.
