How much does blocked drain cost in 2026?
Drainage firms price in three ways: a fixed fee for domestic unblocking (most common in 2026), an hourly rate plus call-out, or a day rate for larger jobs. The table below shows typical 2026 UK prices for the most common drain jobs, from a quick rod to a full CCTV survey.
| Job type | Typical 2026 range | Notes |
|---|---|---|
| Standard call-out (scheduled) | £50–£100 | Often waived or rolled into a fixed fee |
| Drain rodding (manual) | £80–£145 | Best for soft blockages with good access |
| High-pressure water jetting | £150–£300 | For grease, roots and stubborn blockages |
| Fixed-fee domestic unblocking | £100–£250 | Set price regardless of time taken |
| Emergency / out-of-hours call-out | £180–£350 | Adds an £80–£180 premium on top of base |
| Basic CCTV survey (look & see) | £100–£150 | No detailed written report |
| Full CCTV survey with report | £200–£400 | WRc-style report, video and pipe map |
| Day rate (larger / repeat jobs) | £215–£280 | North of England lower, London higher |
What affects the cost
No two blockages cost the same. The biggest factors in 2026 are:
- Clearance method. Manual rodding is the cheapest (£80–£145). High-pressure jetting costs more (£150–£300) but shifts grease, scale and root ingress that rods can't.
- Where the blockage is. An accessible gully or inspection chamber is quick; a blockage deep in the run, under a patio or shared with neighbours takes longer.
- Timing. Standard working hours are cheapest. Evenings, weekends and bank holidays carry an £80–£180 emergency premium.
- Severity. A one-off blockage is a flat job; recurring blockages, collapsed sections or root ingress need investigation and repair.
- Location. London and the South East run 25–50% above the national average; the North and Scotland are often 15–25% below.
Rodding vs jetting vs CCTV — which do you need?
Most homeowners only need one method, but firms sometimes upsell. Here's the honest version:
- Rodding uses flexible rods to push or pull a blockage clear. Cheapest and perfectly adequate for soft blockages (wet wipes, food, light fat) with good access.
- Water jetting blasts the pipe clean with high-pressure water. Worth it for grease, scale, silt and root ingress, or when rodding fails. Expect £150–£300.
- CCTV survey sends a camera down the pipe. You don't need one to clear a simple blockage — but if a drain blocks repeatedly, or you're buying a house, a survey (£100–£400) finds cracks, collapses and misconnections before you spend money digging.
A reputable firm will rod first and only escalate to jetting if needed — not the other way round.
Who's liable — you or the water company?
This is where homeowners lose the most money, paying for clearances they shouldn't. Since the 2011 private sewer transfer:
- You are responsible for drains inside your property boundary that serve only your home.
- Your water company (Thames Water, Severn Trent, Yorkshire Water, etc.) is responsible for lateral drains — the pipe from your boundary to the public sewer — and any pipe shared by two or more properties, even if it runs under your garden.
If several homes on your street are affected, or the blockage is beyond your boundary, call your water company first — they'll often clear it for free. Don't let a private firm clear a public sewer and bill you for it. If you have buildings insurance, accidental drain damage (not blockages) may also be covered.
Common extras & hidden costs
The headline price rarely covers everything. Watch for:
- Call-out fees added on top of the hourly rate (£50–£100).
- Emergency / out-of-hours premiums of £80–£180.
- CCTV survey if the blockage won't clear (£100–£400).
- Descaling or de-rooting as a separate line item.
- London surcharges — congestion charge (£15) and parking added to quotes inside the M25.
- Repair work if the survey finds a collapse: patch (no-dig) liners from £350, excavation and replacement £1,000–£5,000+.
How to save money without cutting corners
You can cut the bill significantly with a few smart moves:
- Check whether the water company is liable before calling a private firm — a free clearance beats any quote.
- Try a plunger or drain rods yourself on a minor, accessible blockage before paying for a call-out.
- Book in standard hours unless it's a genuine emergency (sewage backing up indoors).
- Ask for a fixed price for clearing the blockage, not an open-ended hourly rate.
- Get the engineer to confirm the cause — if it's grease or roots, fixing the habit or doing a one-off jet stops repeat bills.
DIY vs hiring a pro
A surprising amount of drain clearance is DIY-able. A £10 plunger or a £20 set of drain rods will shift a soft blockage in an accessible gully or inspection chamber, saving the whole call-out. Enzyme or caustic drain cleaners can help with grease in waste pipes.
Call a professional when: the blockage is deep in the run or under hard standing; sewage is backing up into the house; you've tried rodding and it won't shift; or you suspect roots or a collapse (recurring blockages, gurgling, slow drainage across multiple fixtures). At that point jetting and a CCTV survey are jobs for a kitted-out firm, not a homeowner.
Regional price differences (2026)
Drain clearance prices vary widely by region in 2026, driven mostly by labour rates, travel and parking. London commands the biggest premium; the North and Scotland are typically cheapest.
| Region | Typical 2026 range |
|---|---|
| London | £160–£350 |
| South East | £130–£280 |
| Midlands | £110–£220 |
| North of England | £100–£200 |
| Scotland & Wales | £100–£200 |

Get real quotesHow to save money
- Confirm whether the drain is the water company's responsibility before you pay anyone — shared and lateral drains are usually free to clear.
- Try a plunger or a £20 set of drain rods yourself on a minor, accessible blockage first.
- Book in standard working hours to avoid the £80–£180 emergency surcharge.
- Insist on a fixed price for clearing the blockage rather than an open hourly rate.
- Get the engineer to identify the cause so you can stop the same blockage recurring.
- Pour fats and oils into a tub, not the sink, and bin wet wipes — prevention is far cheaper than clearance.
- If a drain blocks repeatedly, pay once for a CCTV survey rather than for clearance after clearance.
How long it takes
- Simple rodding job: 30–60 minutes on a single visit.
- Jetting a stubborn or greasy drain: 1–2 hours.
- CCTV survey: 1–2 hours on site, written report within 24–72 hours.
- Emergency call-out: most firms attend within 1–4 hours.
- Excavation repair (if a collapse is found): 1–3 days depending on access and reinstatement.

How to choose the right plumbers
Drainage isn't a licensed trade like gas, so accreditations matter. Look for membership of trade bodies and proper insurance, and avoid anyone who quotes vaguely over the phone then inflates the bill on arrival.
- Are they a member of a recognised body such as the National Association of Drainage Contractors (NADC) or accredited on Checkatrade / Which? Trusted Traders?
- Will they give a fixed price for clearing the blockage before starting?
- Do they carry public liability insurance?
- What is the call-out fee and the out-of-hours rate?
- Do prices include VAT?
- Will they tell you if the blockage is the water company's responsibility?
- Can they provide a CCTV survey and written report if needed?
- Do they offer any guarantee that the blockage won't immediately return?
Blocked drain cost FAQs
How much does it cost to unblock a drain in 2026?
A single domestic blocked drain typically costs £100–£250 to clear in standard hours. Rodding is cheapest at £80–£145; jetting runs £150–£300. London and emergencies cost more.
How much is an emergency drain call-out?
Emergency and out-of-hours call-outs add an £80–£180 premium on top of the base price, so a same-day or night-time clearance often totals £180–£350.
What's the difference between rodding and jetting?
Rodding pushes a blockage clear with flexible rods and is cheapest. Jetting uses high-pressure water to scour the pipe and is better for grease, scale and root ingress, but costs £150–£300.
Who is responsible for a blocked drain — me or the water company?
You're responsible for drains inside your boundary that serve only your home. Your water company is responsible for lateral drains and any pipe shared by two or more properties, even under your garden. Always check before paying.
Will the water company clear a blocked drain for free?
If the blockage is in a lateral or shared drain (their responsibility since the 2011 transfer), yes — they'll usually clear it at no cost. Call them before hiring a private firm if several homes are affected or the blockage is beyond your boundary.
How much does a CCTV drain survey cost?
A basic look-and-see survey is £100–£150; a full survey with a written report and pipe map is £200–£400. A homebuyer survey can reach £400. Worth it for recurring blockages or before buying a house.
Can I unblock a drain myself?
Often yes. A plunger or a £20 set of drain rods will clear a soft blockage in an accessible gully or chamber. Call a pro if the blockage is deep, sewage is backing up indoors, or rodding fails.
Why does my drain keep blocking?
Recurring blockages usually mean a deeper problem — grease build-up, root ingress, a sag, or a partial collapse. A one-off CCTV survey (£100–£400) finds the cause and saves paying for repeat clearances.
Does buildings insurance cover blocked drains?
Insurance generally covers accidental damage to private drains (such as a collapse), not routine blockages. Check your policy — some include accidental damage and trace-and-access cover.
How much does it cost to fix a collapsed drain?
A no-dig resin patch starts around £350. Excavation and replacement runs £1,000–£5,000+ depending on depth, surface type and the length of pipe affected.
