CLEARMASTERS
Grease traps for restaurants and bars
From Rye Lane takeaways to kitchens in arches and rooftop bars, we empty grease traps on a schedule that suits your trade, with a waste transfer note every visit.
Learn morePeckham has become one of south London’s liveliest places to eat and drink, with restaurants, rooftop bars and food businesses in shops, car parks and railway arches alongside the traditional businesses of Rye Lane. All of those kitchens need grease traps emptied and drains kept flowing.
Railway arches and converted industrial units often have long, awkward drain runs that weren’t designed for commercial kitchens. Behind the high street, Victorian terraces in Nunhead, Peckham Rye and Bellenden have old clay drains, many shared and some split between flats.
Our crews work in south London most days and we answer the phone 24 hours a day, 365 days a year.

What we do for Peckham customers
Drains in arches and converted units
Arch and industrial units often have long or shallow drain runs that block easily with fat and food waste. We jet them clear and tell you how to keep them that way.
Learn more
CCTV surveys for terraces and flats
Before buying, or when a drain keeps blocking, a CCTV survey shows the condition of old clay drains, with a written report and photos.

Gullies, yards and pumps
We clean gullies in yards and car parks, and service the pumps some lower-ground flats and commercial units rely on.

Drainage in Peckham: what to know
New kitchens in old buildings.
Kitchens in arches
Railway arches and old units weren’t built for commercial kitchens. A grease trap and regular jetting keep long drains flowing.
Victorian terraces
Old clay drains in the terraces crack and let roots in. Repeated blockages are worth a survey.
Shared drains
Many homes share a drain run. Shared sections are usually the water company’s responsibility.

★★★★★I've used Clearmasters for at least 10 years and always find them reliable, helpful, knowledgable and great at what is a really unpleasant job! I won't use anyone else.
★★★★★I have used Clearmasters now for 4 years and the service has been excellent. Very punctual on the day and their planning team have always been very helpful in finding convenient dates to service and maintain our pumps and tanks. I recommend.

Questions answered
Peckham drainage FAQs
What restaurants, arch businesses and residents in Peckham ask us most.
Does our arch kitchen need a grease trap?
If you’re cooking commercially, you should have one. It protects your drain and the public sewer, and water companies can act against businesses that cause fat blockages.
Why does our arch drain keep blocking?
Long, shallow runs with little fall let fat and food settle. A grease trap plus regular jetting usually solves it.
How often should a busy bar’s grease trap be emptied?
It depends on the trap’s size and your food volume. We’ll suggest a schedule and adjust it.
Should I survey the drains before buying a terrace?
It’s worth it for an older house. A survey shows cracks, roots or collapses before you commit.
Do you clean yard gullies?
Yes, at shops, arches and car parks, with waste transfer notes.
Are you available out of hours?
Yes. We answer the phone 24 hours a day, 365 days a year. Call 03333 233566.
