The short answer
High-pressure drain jetting in the UK typically costs between £100 and £300 for a domestic job, with most straightforward jetting visits landing around £120–£250. The price depends on the severity of the blockage, the length and accessibility of the pipework, and whether it is an emergency or out-of-hours call. Jetting uses a high-pressure water hose to scour away fat, grease, scale and root build-up that manual rodding cannot shift, which is why it costs more than basic rodding. For commercial or heavily blocked systems, costs can be higher. Confirm whether the quote is fixed or hourly, and whether a follow-up survey is included.
Jetting is the go-to method for stubborn, deep or recurring blockages. The sections below explain what it costs, what drives the price, and how it compares with the cheaper but less powerful option of rodding.

Typical cost by scenario
Jetting prices move with how bad the blockage is and how much pipework needs clearing. A single accessible run cleared during normal hours is at the lower end, while a long, deep or compacted blockage, or one needing an emergency visit, sits higher. The method works by feeding a hose with a specialised nozzle into the drain and forcing water through it at high pressure. The nozzle's jets pull the hose along the pipe and blast away build-up from the walls, flushing the debris down to the sewer. Because it scours the whole circumference of the pipe rather than just punching a hole through the blockage, jetting tends to give a more complete and longer-lasting result than rodding. The figures below are indicative ranges to help you judge a quote.
| Scenario | Indicative UK cost | Notes |
|---|---|---|
| Single run, normal hours | £100–£180 | Accessible, moderate blockage |
| Heavy fat / scale / roots | £150–£300 | Compacted or deep build-up |
| Emergency / out-of-hours | £200–£400+ | Nights, weekends, holidays |
| Jetting plus CCTV survey | £180–£450 | Clear then inspect the cause |
| Recurring problem return visit | Often discounted | If booked within a warranty period |

What drives the cost
The main factors are straightforward once you know them, and several are within your control:
- Severity: a light grease film clears quickly; compacted fat or root ingress needs longer and repeat passes.
- Pipe length and access: long underground runs and awkward chambers take more time, and the engineer may need to trace the line first.
- Timing: emergency, weekend and bank-holiday visits carry a premium, often with a separate callout fee.
- Add-ons: a CCTV survey to confirm the cause, or root cutting where roots have grown into the pipe, adds to the price.
- Region: rates in London and the South East are typically higher than the national average.
- Property type: commercial drains and larger systems cost more than a single domestic run.
Because jetting needs specialist equipment and a trained operator, it almost always costs more than basic rodding, but it is more effective on the blockages rodding leaves behind. You can keep the price down by booking a daytime appointment where the situation is not urgent, and by clearing access to inspection chambers in advance.
When jetting is the right choice — and when to add a survey
Jetting is the appropriate method when a blockage is caused by build-up that coats the pipe, such as cooled fat, oil and grease, limescale and mineral scale, or fine root growth through joints. It is also the better choice for a recurring blockage in the same spot, because it removes the layer that keeps catching debris rather than just clearing a channel through it. For a one-off soft clog near the surface, rodding is usually enough and cheaper.
Where a drain blocks repeatedly, pairing jetting with a CCTV survey is often better value than repeated clearances. The survey shows whether the cause is something jetting can fix permanently, such as grease, or a structural fault like a cracked or displaced pipe that will keep collecting debris until it is repaired. Spending a little more on a survey can save paying for the same jetting job again and again. A reputable engineer will recommend a survey if a blockage keeps returning rather than simply rebooking the clearance.
What to expect during a jetting visit
Knowing how a typical visit unfolds helps you judge whether you are getting value for the price. The engineer first locates and lifts an inspection chamber to access the line, then feeds the jetting hose in and works it along the pipe, the nozzle's rear-facing jets dragging it forward while the water scours the walls. They usually run the jet back and forth several times to break up and flush away the build-up, checking the flow at the chamber to confirm it has cleared. A thorough operator will keep going until water runs freely rather than stopping at the first sign of improvement, since a half-cleared pipe simply blocks again.
A good visit often ends with the engineer telling you what caused the blockage and how to avoid a repeat, for example by keeping fat and food waste out of the kitchen sink. For a recurring problem, this is also the point at which they may suggest a CCTV survey to check for an underlying fault. To keep the result lasting and avoid paying for jetting again, the most effective habits are simple: never pour fat, oil or grease down the sink, scrape plates into the bin, fit strainers over plugholes to catch food and hair, and only flush pee, paper and poo. These cost nothing and directly tackle the build-up that jetting has just removed.
Jetting vs rodding — which to pay for
Manual rodding pushes a flexible rod through the pipe to dislodge a blockage near the surface, and it is the cheaper first step for simple clogs. Jetting uses pressurised water to cut through and flush away build-up along the whole pipe wall, making it more thorough for fat, grease, limescale and fine root ingress. A drainage engineer will often try rodding first and move to jetting if the blockage is stubborn or recurring. If the same drain keeps blocking, jetting combined with a CCTV survey is usually better value than repeated rodding, because it tackles the cause rather than the symptom.
It is also worth noting who is responsible for the pipe before you pay. Following the 2011 sewer transfer, most shared lateral drains and public sewers are the regional water company's responsibility, and they may carry out the jetting at no cost. If several properties are affected, or wastewater is overflowing from a shared manhole, contact your water company before booking a private firm, as the work may not be yours to fund.
Frequently asked questions
Is jetting better than rodding?
Jetting is more thorough for fat, grease, scale and root build-up because it scours the whole pipe wall, while rodding only dislodges blockages near the surface. Rodding is cheaper and often tried first, with jetting used for stubborn or recurring blockages.
Can jetting damage my pipes?
On sound pipework jetting is safe, but on old, cracked or weakened pipes high pressure can worsen existing damage. A CCTV check beforehand helps confirm the pipes can take it, which is why a survey is often recommended for older properties.
How long does drain jetting take?
A typical domestic jetting job takes roughly one to two hours, though heavily compacted blockages or long runs can take longer. Emergency visits are usually focused on clearing the immediate problem rather than a full clean of the system.
