South Ruislip grease trap cleaning

- An interceptor full of grease and solids
- Foul odours from the grease trap
When to call us in South Ruislip
A full trap can’t hold any more grease. It goes on into the drain and on towards the sewer, where it can cause blockages.
These are the problems we see most often:
- An interceptor full of grease and solids
- Grease setting in the kitchen pipework
- Gurgling from the sink waste
- An under-sink unit that needs regular emptying
Healthcare kitchens cook through the year, so a deep clean has to be fitted around meals; Clementine Churchill Hospital, about 2.7 miles east, is the nearest hospital to South Ruislip.

Grease trap cleaning for kitchens and businesses in South Ruislip
If the sinks drain slowly or smell, the trap is often the cause. In South Ruislip, as everywhere we work, our team empties and cleans the trap, then check the water flows properly. We’re often asked to deal with an overdue grease trap and sinks that drain slowly, across under-sink grease traps, kitchen waste pipes and pot wash sinks.
Every food business in London is inspected by its local council’s environmental health officers, and the cleanliness of the whole kitchen is part of what they look at. Kitchens in South Ruislip often book a deep clean before or after an inspection.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Common questions in South Ruislip
Do you clean school kitchens in South Ruislip in the summer holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 30 schools and colleges with food registrations within roughly a mile and a half of South Ruislip. Tell us your holiday dates and we will book the visit for when the site is empty.
Does London parking affect a job in South Ruislip?
London parking can be tight, so details of loading bays and permits help. Working overnight, as we often do in London, usually makes it simpler.
Do I get a report after the visit?
Yes. It’s the record insurers and inspectors ask to see: a dated report with photos, listing the work and any areas we couldn’t reach.
What about areas you can’t get to?
Anything we can’t reach goes on the report, with photos where possible, and we explain what access is needed, such as extra access panels in ductwork.
What types of grease trap do you clean?
We cover under-sink, inline and interceptor units. They’re emptied, cleaned and checked in the same careful way.
Which records should we keep?
Visit reports, certificates and your in-house cleaning logs. Insurers, fire officers and EHOs may all ask to see them, so keep them together and easy to find.
Can you come out in an emergency?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we’ll advise on what to do next.
How regularly does a grease trap need emptying?
That depends on the trap and the kitchen. A small trap fills more quickly than a large one, and busy kitchens fill them faster still. We will recommend a schedule once we’ve seen it.
Commercial kitchens in South Ruislip
Look up South Ruislip on the FSA’s food hygiene register and you’ll find about 146 cafés, restaurants and staff canteens and about 78 sandwich bars and takeaways within roughly a mile and a half of the centre of South Ruislip. Wherever they wash pans and plates, fat heads for the drain unless a trap catches it. It’s Hillingdon council that sends environmental health officers to food businesses in South Ruislip. Grease behind equipment or on a ceiling is the kind of thing an inspection can note. Photos and dates from each deep clean make a useful record. Fat from London kitchens contributes to sewer blockages, which is why grease traps need emptying on a schedule.
If you run a café or takeaway near South Ruislip station, a deep clean overnight means the kitchen opens as normal next morning. Where a church or community hall near Church of St Mary, or anywhere in South Ruislip, has a kitchen used by volunteers, a periodic deep clean keeps it ready for the next event.

Why it’s worth doing now in South Ruislip
Grease that gets past the trap does not disappear. It can build up in the drains and join fatbergs in the sewer. A well-maintained trap keeps it where it can be removed. In South Ruislip, as across London, ductwork often passes through shared risers and other people’s space.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.

What affects the quote in South Ruislip
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The condition of the system
- The number of sites or systems
- Parking and loading at the site
- Any permits to work or inductions
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered and we will price it together.
Asking for a quote
When you call or email, it’s useful to have:
- Any access panels or hatches you can see
- Problems your staff have spotted
- Photos showing the whole system and its surroundings
- The roof, plant room or outside wall the system runs to
Here’s what helps us quote: where the site is, what it is and its opening hours, photos of the system and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711 or send us an email.
The process
Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit takes an hour or two in most kitchens, depending on the size and condition of the trap. In a London area like South Ruislip, parking, loading and building access are planned before the day of the work.
- We agree a time when the sinks aren’t needed.
- The trap is opened up and checked.
- We remove the grease layer and settled solids.
- The inside, baffles and outlet are cleaned.
- We close it up, check it drains and suggest when it needs cleaning again.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Make sure someone can let us in and lock up afterwards
- Have your last certificate or report to hand
Getting a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
Related advice
Between visits
A little care between visits keeps the system in better shape. We recommend:
- Don’t wait for a blockage to book a clean
- Keep access to the trap clear
- Keep strainers in every sink
- Get food waste into the bin, not the sink
If we spot problems beyond the trap, such as a drain that still runs slowly, we will tell you. It may need a drainage specialist to investigate.
Setting regular cleans takes the guesswork out. The interval is set to suit the trap and the kitchen.

Drains in care settings need to keep flowing. Visits are planned between meals.
Under-sink grease traps
An under-sink trap is out of sight. A full one shows itself with a slow, smelly sink.
In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
