Water backing up instead of draining away is stressful, especially if it's a toilet or the only sink in the house. Most of the time it's fixable same-day — the trick is knowing whether to try it yourself, what a fair call-out actually costs, and how to avoid a bigger bill from someone who clears the symptom but not the cause.

A specialist typically clears a straightforward blockage same-day using high-pressure jetting; recurring blockages usually need a CCTV drain survey to find the actual cause (a collapsed pipe, root ingress, or a misaligned joint) rather than just clearing the symptom repeatedly.

Most local specialists are competent — but here's what separates one you'll want to call again from one you won't:

Indicative UK-wide ranges: a straightforward single-drain call-out typically runs £60-£150. A CCTV drain survey (needed for recurring blockages, to diagnose the actual cause) typically adds £100-£250. Root cutting or more complex jetting work can run higher. These are general UK ranges, not locally-verified quotes — always get a firm price before work starts, and confirm whether it includes VAT.
A plunger or a bottle of drain cleaner is worth trying first for a single slow-draining sink. If that doesn't work, if multiple drains are affected at once (a sign the blockage is further down the shared pipework), or if it's a toilet, call a specialist — DIY drain rods can push a blockage further in or damage pipework if used incorrectly.
Unblocking clears the immediate blockage (usually by jetting). A CCTV survey sends a camera down the pipe to show you what's actually wrong — useful if the same drain keeps blocking, since it tells you whether it's a one-off (e.g. wipes) or a structural issue (root ingress, a cracked pipe) that jetting alone won't fix long-term.
