What counts as an emergency drain unblocking job?

We treat emergency drain unblocking as anything where waiting until the next working day would cause property damage, health risk, or operational shutdown. The most common London emergencies are sewage backing up through internal fixtures, external manholes overflowing in heavy rain, commercial kitchens unable to trade because of a blocked grease run, and converted-flat shared stacks failing across multiple floors.

We dispatch the nearest available engineer immediately when you call. Response times are 60–90 minutes across the inner and outer boroughs, and we operate fully 24/7 including nights, weekends, and bank holidays. There is no call-out fee — you pay only the fixed price agreed in writing once the engineer is on site and has scoped the job.

Emergency drain unblocking pricing in London

Emergency drain unblocking in London starts at £120 for a single residential blockage attended in the standard daytime emergency band, and rises to around £300 for complex main-drain emergencies with restricted access. Out-of-hours work — evenings, weekends, and bank holidays — adds £40–£80 to the standard rate.

We confirm a fixed price in writing before any work begins. There is no diagnostic charge, no separate equipment fee, and no surprise add-ons once the job is underway.

What to do while you wait for the engineer

Stop using all water in the property — every flush, tap, dishwasher cycle, and washing-machine cycle sends more water into an already-failed drainage system. Lay towels or absorbent material to contain any sewage overflow. Keep children and pets away from contaminated water. Open windows for ventilation if foul odours are present.

If you can see waste backing up from an external manhole, do not attempt to lift the cover or clear the blockage yourself with chemicals — these can damage older Victorian clay pipes and create a worse problem for the engineer to resolve.
