A dirty grease trap smells. Rotting food and grease give off foul odours and the smell carries. Cleaning it removes the cause. Planning ahead in Childs Hill lets you pick a quiet night rather than lose a busy one.

Grease trap cleaning in Childs Hill, done properly
Fats, oils and grease are the main cause of blocked kitchen drains. Down the line, they can add to fatbergs in the sewer. A well-maintained trap keeps them out of the drains. Common call-outs are for an under-sink unit that needs regular emptying and an interceptor full of grease and solids, across under-sink grease traps, inline grease traps and school and care home kitchens.
Across London, many commercial kitchens are compact and run long hours, and grease builds up behind and under equipment, on walls and ceilings, and in the drains. In Childs Hill, deep cleans and grease trap work are normally done overnight.
A written report with photos follows every visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What the work involves, part by part
School, care home and staff kitchens
Care home and hospital kitchens need their drains working all the time. Visits are planned between meals.
Inline grease traps
Access to an inline trap can be in a floor or cupboard. We ask about access when we quote.
What we do, step by step
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before we start, and floors and nearby surfaces are sheeted. The work itself takes an hour or so for an under-sink trap, longer for a larger unit. Before any visit in Childs Hill, we agree where the van can stop and how equipment reaches the system.
- We start by finding the trap and checking its inlet and outlet.
- Nothing drains into the trap while it’s open.
- The trap is emptied of grease and food waste.
- Every part of the trap is scraped and cleaned, including the baffles.
- We put it back together, run water through and remove the waste.
Preparing for the visit
- Have your last certificate or report to hand
- Let us know how we reach the system, including roofs, risers and plant rooms
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
We do not publish a price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, give us a ring on 0345 646 2711, or send details by email.
Related advice
In-house cleaning or a specialist?
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Signs you need grease trap cleaning in Childs Hill
Every pan and plate washed sends grease towards the drain. They cool and float to the top of the trap, and the layer gets thicker day by day.
Any of these means the system needs a check-up:
- An interceptor full of grease and solids
- Gurgling from the sink waste
- A grease trap that hasn’t been emptied in a long time
- A blocked kitchen drain caused by grease
If you run a care home or healthcare kitchen near Childs Hill (the nearest hospital is New End Hospital, about 0.9 miles east), a grease trap on a set schedule avoids a blocked drain mid-service.

FAQs for Childs Hill
Can you come to Childs Hill after we close?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
How do you handle parking and loading in Childs Hill?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Much of our London work is done overnight, which helps.
Will cleaning the grease trap fix a blocked drain?
We clean the trap, not the drain network. If the drain beyond the trap is blocked or damaged, we will tell you and suggest a drainage contractor.
Is there a survey before the work?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Is TR19 cleaning required by law?
No. TR19® is BESA’s specification, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
How far ahead should we book?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
What happens to the waste?
It leaves the site with us when we go. During the work, it’s contained to keep the area clean.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Grease trap cleaning around Childs Hill
There are about 8 food manufacturers and packers within roughly a mile and a half of the centre of Childs Hill, 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. Kitchens in Childs Hill get their food hygiene inspections from Barnet council. The state of floors, drains and hard-to-reach corners all feeds into the inspection. A record of each deep clean helps show the kitchen is kept in order. Compact London kitchens collect grease in tight corners, which an overnight deep clean can reach.
Where a church or community hall near All Saints, or anywhere in Childs Hill, has a kitchen used by volunteers, a periodic deep clean keeps it ready for the next event. School kitchens, at schools like All Saints' CofE Primary School NW2 for example, typically have their deep cleans and grease trap work done while the canteen is closed.

Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Aftercare tips
Results last longer with the right care. We suggest:
- Do not wait for a blockage to book a clean
- Act on gurgling or smelly drains
- Don’t rely on hot water to clear grease
- Do not store things on top of the trap
Collect waste cooking oil separately rather than pouring it down the sink and the trap will not fill as quickly. It makes a real difference.
Setting regular cleans takes the guesswork out. We agree the timing with you.
