Grease traps for Brixton’s restaurants and market traders, and drains and CCTV surveys for its terraces and flats.
Brixton’s food scene, from the market arcades and Pop Brixton to the restaurants and takeaways along Coldharbour Lane and Atlantic Road, produces an enormous amount of fat, oil and grease. Grease traps that are emptied on time keep kitchens trading and stop fat setting hard in the drains under the streets.
Away from the centre, Brixton is streets of Victorian terraces, many split into flats, with old clay drains that are often shared. The buried River Effra runs beneath the area, and low-lying streets can be slow to drain after heavy rain.
Our crews work in south London most days and we answer the phone 24 hours a day, 365 days a year.
Small kitchens in market units and arcades often have small grease traps that fill quickly. We empty them on a schedule that matches how busy you are, before or after trading, and leave a waste transfer note every time.

We clear blocked drains in houses and flats with high-pressure jetting and help you work out whether it’s your drain, a neighbour’s or a shared sewer.

A CCTV survey shows the condition of a terrace’s drains, with a written report and photos you can keep or pass to a buyer, landlord or insurer.

Lower-ground flats below the sewer depend on pumps. We service them, test the alarms, and come out 24/7 if one fails.

A busy food scene on top of old drains.
Market and arcade kitchens often have small grease traps that fill fast. Regular emptying is cheaper than a blocked drain.
Many terraces share a drain run. Shared sections are usually the water company’s responsibility.
Some low-lying streets drain slowly after heavy rain. Clear gullies make a difference.
