Greater London · Grease trap cleaning
Grease trap cleaning in Winchmore Hill, Greater London
Grease trap cleaning in Winchmore Hill from ventilation hygiene specialists trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Washing-up water that won’t drain away
- An under-sink unit that needs regular emptying
- A grease trap that hasn’t been emptied in a long time
What happens if it’s left?
Some kitchens try to fix slow drains with hot water or drain cleaners. That only moves the grease further down the pipe, where it sets again. The lasting fix starts with the trap. Choosing the date yourself beats having a fault choose it for you.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, phone us on 0345 646 2711, or email photos for straight advice and a fixed quote.

How we handle grease trap cleaning in Winchmore Hill
Grease traps sit between the sinks and the drain, holding back fats, oils and grease. As the waste water cools, the grease floats and stays in the trap, and clean water flows on. Over time, the trap fills up and needs emptying and cleaning. If you have a blocked kitchen drain caused by grease and gurgling from the sink waste, we can put it right, from under-sink grease traps, school and care home kitchens and pot wash sinks onwards.
Across London, council environmental health teams inspect food businesses, and the cleanliness of the whole kitchen is part of what they look at. A deep clean ahead of an inspection, or after one, is a common reason kitchens in Winchmore Hill get in touch.
The report is your system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

What the work involves, part by part
Under-sink grease traps
Under-sink traps are cleaned in a short visit, and check the lid and seals.
Inline grease traps
Inline traps are fitted into the drain line. They’re larger than under-sink traps but still need regular emptying.
How it works
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes anything from under an hour to a few hours, depending on the trap. Getting kit into a London building takes planning, so let us know where we can load and park in Winchmore Hill.
- First, we find the trap and look at its connections.
- We make sure nothing drains into the trap.
- Grease and solids are removed from the trap.
- We clean every part of the inside.
- We refit it, run water through and remove the waste.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Clear loose items from the work area
- Arrange a key holder or contact on site
Getting a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.

Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- Keep access to the trap clear
- Fit sink strainers to catch food scraps
- Do not wait for a blockage to book a clean
- Scrape plates and pans into the bin before washing up
You will get our view on how often the trap needs cleaning. That depends on how quickly it filled and how busy the kitchen is.
If the kitchen has got busier, the trap fills faster. Booking cleans more often keeps the drains flowing.
Common questions in Winchmore Hill
Can school kitchens in Winchmore Hill be cleaned in the holidays?
Yes, and it’s the easiest time to do it. There are about 39 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Winchmore Hill. Send us your term dates when you give us a ring on 0345 646 2711, or send details by email, and we’ll fit the work in.
What do you need to know about parking in Winchmore Hill?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Every site has its own report.
How often should a grease trap be cleaned?
The right interval depends on your trap and your cooking. If the sinks start to drain slowly between cleans, it’s too long, and we can shorten it.
Do you have insurance?
Yes, we are fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line, for problems that cannot wait. Ring any time and tell us what’s happened.
Where does the waste go?
It leaves the site with us at the end of the visit. While we work, it’s kept contained to keep the area clean.
Do you clean under-sink and inline grease traps?
Both under-sink and inline traps, plus interceptors. If you’re not sure what you have, send us a photo and we will confirm.
What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
For landlords and multi-site operators
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
