If you have a blocked drain and need to know what it will cost before calling anyone, this guide gives you accurate UK pricing for 2026 — based on what drainage work actually costs, not vague ranges that tell you nothing useful.
How Drain Unblocking Pricing Works
Drainage companies price blocked drain work in one of two ways: a fixed price for the job, or an hourly rate plus a call-out fee. Fixed pricing is almost always better value.
A fixed price is agreed before any work starts. It covers clearing the blockage regardless of how long the engineer takes. You know exactly what you are paying before a tool is put near your drain.
Hourly rate pricing creates uncertainty. An engineer on £75 to £150 per hour who takes three hours on a stubborn blockage will cost far more than a fixed-price alternative. You have no way of knowing the final cost until the work is finished.
At Drain Unblocker Leeds, we always quote a fixed price before starting. There is no call-out fee. You pay only for the work.
Drain Unblocking Costs UK 2026
These are accurate price ranges for professional drain unblocking in 2026:
- Residential sink or toilet blockage (simple access): £60 to £120
- Outside drain or gully unblocking: £80 to £150
- High-pressure drain jetting (standard residential): £100 to £200
- CCTV drain survey (inspection and condition report): £100 to £250
- Emergency drain unblocking (nights, weekends, bank holidays): £150 to £300
- Commercial drain unblocking: priced individually — size and complexity vary significantly
Prices at the lower end of each range reflect straightforward access, straightforward blockages, and standard hours. Prices at the upper end reflect difficult access, stubborn blockages, or emergency callouts outside standard hours.
Prices below these ranges often indicate a company without proper equipment — one that uses rods rather than jetting, leaving the drain more likely to block again soon. Prices significantly above these ranges warrant scrutiny.
What Affects the Cost
Time of call — Emergency callouts at night, on weekends, or on bank holidays cost more than standard daytime appointments. This is legitimate; engineers working overnight charge a premium. Be cautious of companies that charge emergency rates for appointments booked the following day at a normal time.
Access — Easy access to a manhole or inspection chamber keeps costs lower. Blocked drains accessible only through confined spaces, beneath paving that requires lifting, or needing specialist access equipment cost more.
Depth and distance of blockage — A blockage one metre from the gully clears faster than one 30 metres into the drain run. Greater distance increases jetting time.
Cause of the blockage — A simple grease or paper blockage clears quickly. Tree root intrusion requires a root-cutting jetting nozzle and typically costs more. A structural defect — displaced joint or pipe collapse — requires repair work beyond the initial clearance.
Cost to Unblock Specific Drain Types
- Kitchen sink (residential): £60 to £100 for a simple grease blockage with good access
- Blocked toilet: £60 to £120 (more if the blockage extends beyond the toilet into the external drain)
- Outside drain or gully: £80 to £150 for standard jetting from the gully
- Shower or bath drain: £60 to £100 for hair and soap build-up
- Main drain serving the whole property: £120 to £250
Drain Repair Costs
Where a CCTV drain survey reveals structural damage after unblocking, repair costs vary depending on the type and extent:
- Root cutting and removal (combined with jetting): £150 to £400
- Drain patch repair (small localised damage, no-dig): £500 to £1,200
- Pipe relining (no-dig repair of cracked or root-damaged section): £800 to £2,500 per section
- Drain excavation and pipe replacement (single section): £1,500 to £5,000
Pipe relining is cost-effective when excavation would be disruptive — through a heritage floor, beneath a driveway, or through a mature garden. For accessible sections with extensive damage, excavation and replacement can be more economical.
No Call-Out Fee: What It Actually Means
We do not charge a call-out fee. This means you pay only for the work carried out — not for an engineer travelling to your property or the initial assessment.
Some companies advertise no call-out fee but then quote an "assessment fee" or "diagnostic charge" once on site. These are call-out fees by a different name. Before any engineer begins work, ask directly: is there any charge if I decide not to proceed once you have given me a price?
Our engineers quote a fixed price on arrival. If you decide not to proceed, there is nothing to pay.
How to Avoid Expensive Drain Problems
The cheapest drain callout is the one you never need. A few simple habits significantly reduce the likelihood of blockages:
- Never pour cooking oil, fat, or grease down any drain — let it cool and dispose of it in general waste
- Use mesh drain covers in kitchen sinks and shower trays to catch food and hair
- Flush only toilet paper down toilets — not wet wipes (including "flushable" products), cotton pads, or nappy items
- Clear external gullies of leaf debris each autumn before it compacts
- If you have mature trees near drainage pipes, consider annual CCTV inspection to catch root intrusion early
