How we handle grease trap cleaning in West Barnes
Grease trap cleaning keeps the drains running and the smells away. We empty the built-up grease and food solids, clean the inside and the baffles and the trap checked before we leave. If you have an inline trap or interceptor due for cleaning and a blocked kitchen drain caused by grease, we can put it right, from restaurants and takeaways, under-sink grease traps and kitchen waste pipes onwards.
Across London, council environmental health teams inspect food businesses, and walls, floors, ceilings and equipment are all part of the picture. Kitchens in West Barnes often book a deep clean before or after an inspection.
We have been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

Common questions in West Barnes
Which environmental health team covers West Barnes?
Food hygiene inspections in West Barnes are carried out by Merton council. Inspection results feed into the food hygiene rating published by the Food Standards Agency.
Can you work in school kitchens in West Barnes during the holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 31 schools and colleges with food registrations within roughly a mile and a half of West Barnes. Tell us your holiday dates and we will book the visit for when the site is empty.
How often should a grease trap be cleaned?
That depends on the trap and the kitchen. Small under-sink units fill faster than larger traps and the busier the kitchen, the faster it fills. We’ll suggest an interval after the first clean.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
Why does a grease trap need regular cleaning?
Once it’s full, grease passes straight through. The grease hardens in the pipes, leading to blocked drains and smells and can end up adding to sewer blockages.
How long does a grease trap clean take?
As a guide, it takes an hour or so for an under-sink trap, longer for a larger unit. A large or very full trap takes longer, and we will tell you in advance.
Is West Barnes in your area?
Yes. Our area takes in London and the counties of South East England, West Barnes included.
Do you provide a certificate or report?
Yes. You get a written report with pictures after each visit, covering the work, any areas we couldn’t access and the recommended next date. Where the work is a TR19® Grease clean, there’s also a certificate issued through the BESCA Vent Hygiene Elite portal.
The process
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before work begins, and floors and nearby surfaces are sheeted. The work itself takes a short visit for a small trap and longer for an inline unit or interceptor. In a London area like West Barnes, parking, loading and building access are planned before the day of the work.
- We start by finding the trap and checking its inlet and outlet.
- We ask for the sinks that drain into the trap not to be used.
- We take out the layer of fat, oil and grease and any solids.
- We clean the chambers, baffles and connections.
- Once it’s refitted, water is run through to check it drains, and we take the waste with us.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Agree a time when the area can be out of use
- Let us know how we reach the system, including roofs, risers and plant rooms

What happens if it’s left?
Pests are drawn to grease and food waste. A clean trap is less of an attraction, alongside good kitchen hygiene. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.

Fixed quotes for grease trap cleaning in West Barnes
Every site gets its own quote. This is what makes a difference:
- Whether we need access equipment or extra panels
- The condition of the system
- How big the system is
- Any permits to work or inductions
You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, phone us on 0345 646 2711 or email us, and we’ll talk you through it.
What to send for a quote
Photos let us diagnose from a distance. The most useful are:
- When the site is open and when it’s quiet
- The site address and the type of premises
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The paperwork from the last visit, if you have it
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Multi-site and managed buildings
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Commercial kitchens in West Barnes
There are about 8 food manufacturers and packers within about 1.5 miles of central West Barnes, according to the Food Standards Agency’s register. A production site’s wash-down water can carry plenty of fat, which a trap or interceptor has to catch. Environmental health officers from Merton council inspect food businesses in West Barnes. 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. Compact London kitchens collect grease in tight corners, which an overnight deep clean can reach.
A summer deep clean suits schools such as Sacred Heart Catholic Primary School, as the kitchen can be stripped back with no lunches to serve. Healthcare kitchens, like those at hospitals such as Atkinson Morley Hospital (about 1.2 miles north), cook for long hours, so deep cleans and grease trap work are planned around patients’ meals.

How the job changes from site to site
Inline grease traps
An inline trap sits in the pipework between the kitchen and the drain. They hold more than under-sink units but still need regular emptying.
Grease interceptors
An interceptor works on the same principle as a smaller trap. Grease floats and solids sink.
Keeping the system healthy
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Make sure the trap can be reached easily
- Do not rely on hot water to clear grease
- Collect waste cooking oil separately
- Get food waste into the bin, not the sink
Between cleans, keep food scraps out of the sink. Use strainers in the sink plugholes before they reach the trap.
Slow sinks and a bad smell are early warnings. Acting at this stage typically prevents a blockage later.
