What counts as an emergency drain unblocking job?

We treat a job as an emergency when waiting for the next working day would cause damage, a health risk or a shutdown. The most common London cases are sewage backing up through fixtures and manholes that overflow in heavy rain. Others are commercial kitchens that cannot trade because of a blocked grease run, and shared stacks in converted flats that fail across several floors.

When you request a quote online, we arrange for an engineer to attend, in inner and outer boroughs alike. The engineer scopes the job, and we then confirm the price with you.

Emergency drain unblocking pricing in London

The cost depends on several things. A single home blockage in the standard daytime band costs less, while a complex main-drain emergency with tight access costs more. Work out of hours, such as evenings, weekends and bank holidays, can also change the price. We confirm the price with you before any work begins.

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 a drain that has already failed. Lay towels or other absorbent material to hold back any sewage. Keep children and pets away from dirty water. Open windows if there are foul smells.

If you can see waste backing up from an outside manhole, do not lift the cover. Do not use chemicals to clear it either, because they can harm older Victorian clay pipes. That would leave the engineer a worse problem to solve.
