How Much Does Drain Unblocking Cost in Twickenham? 2026 Price Guide

A blocked drain rarely picks a convenient moment. Before you call the first number you find, it helps to know what the work actually involves and what a fair price looks like in 2026. This guide gives you honest ranges — not a single headline figure that disappears once a van arrives.

The Three Main Methods and Their Typical Costs

1. Drain Rodding

Rodding is the traditional approach: flexible rods are fed into the drain to break up or push through a blockage. It suits straightforward obstructions close to an access point — a build-up of grease, a clump of wipes, or a dislodged piece of debris.

• Typical range: £60–£150 for a standard domestic job during normal hours
• Out-of-hours or weekend call-outs will carry a premium, usually £30–£60 on top
• Most simple kitchen or bathroom drain blockages fall into this bracket

2. High-Pressure Water Jetting

Jetting uses a powerful water jet to blast scale, fat and root ingress from the pipe walls, not just punch a hole through the blockage. It is more thorough than rodding and is often the right choice for recurring blockages or longer drain runs.

• Typical range: £100–£300 depending on drain length, access and severity
• Larger properties, shared drains or commercial premises sit toward the top of that range
• Some companies quote jetting as a flat rate; others charge by time — ask before they start

3. CCTV Drain Survey

If the blockage keeps coming back, or if you want to know why it blocked, a CCTV camera survey gives you a recorded view of the inside of the pipe.

• Typical range: £150–£350 for a standard residential survey
• You receive a written report and footage — useful if you need to discuss the findings with a landlord or your buildings insurer
• Often recommended before any excavation work is agreed

What Pushes the Price Up

Several factors can move a quote from the lower end to the higher end — or beyond:

• Time of day. Emergency call-outs at night, at weekends or on bank holidays carry a legitimate premium. A 2 a.m. call-out in Twickenham will cost more than a Tuesday afternoon appointment.
• Access difficulties. Drains under decking, behind locked gates, or with no rodding eye nearby take longer to reach.
• Root ingress. Tree roots entering a cracked pipe require jetting plus potentially lining or excavation. Root cutting alone can add £100–£250 to a job.
• Collapsed or cracked pipework. If the CCTV reveals a structural defect, unblocking is only the first step. Patch lining, no-dig repair or open excavation are separate scopes of work with their own pricing.
• Shared or communal drains. If the blockage is in a section of drain shared with neighbours, or in a lateral drain that Thames Water is responsible for, the situation becomes more complicated before it becomes cheaper.
• Multiple blockages. Occasionally a camera reveals that what felt like one blockage is actually two or three separate points of restriction.

Why the Cheapest Quote Often Isn’t

A low headline price can be genuine — or it can be a door-opener that grows once the van is on your drive. Watch for:

• “From £X” pricing that assumes best-case access and a simple blockage
• Quotes given over the phone without any questions about drain location, access or previous history
• Pressure to agree excavation or lining work on the same visit, without a written scope

A reputable company will ask a few questions first, give you a fixed price (or clearly explain what would trigger a price change), and not start work until you have agreed in writing.

What a Fair Quote Should Include

When you call, a straightforward job should come with:

1. A clear call-out or attendance fee (if any)
2. The method they intend to use — rodding or jetting
3. Whether CCTV is included or an optional extra
4. Any out-of-hours premium, stated upfront
5. What happens if the blockage turns out to be more complex

A Note on Documentation

If your blocked drain has caused internal flooding or damage to flooring or ceilings, ask for a written job report — cause of blockage, photographs, and scope of work completed. That record belongs to you and is what your buildings insurer will ask for if you make a claim. A good plumber provides it as a matter of course.
