What Counts as a Blocked Drain Emergency
A slow-draining sink is inconvenient but not urgent. A drain that's fully blocked, backing up into the property, or causing bad odours and standing water is a genuine emergency that needs same-day attention to avoid water damage or a health hazard.

Credentials to Check Before Hiring
- Public liability insurance, ideally £1 million or more, confirmed before work starts.
- City & Guilds or NVQ Level 2/3 qualifications as a baseline for a trained plumber.
- Drainage-specific experience — ask directly whether they carry CCTV drain inspection equipment for anything beyond a simple blockage.
- A written, fixed quote before the drain rodding or jetting work begins.
Questions to Ask Before You Hire
- Is the call-out fee fixed, and does it come off the total if I go ahead?
- Can you clear the blockage today, or will I need a second visit?
- Do you use CCTV to check for damage further down the drain?
- Is the price fixed once you've assessed the blockage?
- What happens if the blockage returns shortly after?
- Do you charge extra for evening or weekend call-outs?
What to Do Before the Plumber Arrives
- Stop using the affected sink, toilet, bath or shower to avoid making the blockage worse.
- Clear access to the drain, manhole cover or affected fitting.
- Avoid using chemical drain cleaners before the engineer arrives — they can make some blockages harder to diagnose.
- Note how long the drain has been slow or fully blocked.
- Move any items away from areas at risk of overflow.
Warning Signs to Avoid
- A quote that changes significantly once the blockage is found.
- No written price before jetting or rodding work begins.
- Pressure to agree to a full drain replacement without a CCTV survey first.
- No proof of insurance when asked.
- Cash-only payment demanded with no invoice offered.
