When to call us in New Malden
If a trap is not emptied, grease passes straight through. It then builds up in the drains and on towards the sewer, where it can form blockages.
If you notice any of these, it’s worth a diagnosis:
- A bad smell from the sinks or drains
- Grease setting in the kitchen pipework
- An inline trap or interceptor due for cleaning
- A routine grease trap service
For a café close to New Malden station, a deep clean can be done between closing and the morning rush.

About our grease trap cleaning in New Malden
We clean grease traps for kitchens in New Malden, from small under-sink units to inline traps and interceptors. Visits are booked around your service, so the kitchen keeps running. The work covers restaurants and takeaways, inline grease traps and school and care home kitchens, and common reasons people get in touch are a small trap that fills too quickly and drains clogged with fat.
Across London, council environmental health teams inspect food businesses, and walls, floors, ceilings and equipment are all part of the picture. Kitchens in New Malden often book a deep clean before or after an inspection.
Nothing is signed off by word of mouth: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

How the visit works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes an hour or so for an under-sink trap, longer for a larger unit. Loading bays, visitor permits and roof access are the first things we ask about for a site in New Malden.
- We locate the trap and check how it’s fitted.
- Sinks feeding the trap are taken out of use.
- 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.
Getting ready for the visit
- Let us know when the site is closed or quiet
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about permits to work or site inductions

Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.
Related advice
What happens if it’s left?
Once the trap is full, grease heads for the drain. It hardens on the pipe walls, until the drain blocks. Regular trap cleaning beats dealing with a blockage. A busy site in New Malden builds up dirt and wear quickly, so putting it off makes the eventual job larger.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.

Questions from New Malden
Who inspects food businesses in New Malden?
The local authority for New Malden is Kingston-Upon-Thames council, and its environmental health team does the inspecting. How often a business is inspected depends on the council’s risk rating for it, so the kitchen needs to be ready at any time.
Does London parking affect a job in New Malden?
A loading bay, a visitor permit or off-street space near the site in New Malden makes the visit easier to plan. Where restrictions apply in the day, an evening or overnight visit typically gets round them.
What paperwork should we keep on file?
The reports and certificates from each visit, plus your own logs. They’re what an insurer, fire officer or EHO may ask for, so keep them where they can be found quickly.
Do you deal with blocked drains beyond the grease trap?
That depends on the cause. If the trap is full, cleaning it often helps, but blockages further along need a drainage contractor.
How long does a grease trap clean take?
The size and state of the trap make the difference, and you can expect it to take an hour or two in most kitchens, depending on the size and condition of the trap. We’ll confirm when we quote.
What if parts of the system cannot be reached?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
Does the report say when we need you again?
Yes. The report recommends when the next visit should be, based on use and what we found.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
What affects the cost of grease trap cleaning
Before we fix a price, we need to know a few things. We look at:
- Where the site is and how we reach it
- The condition we find in the survey
- How big the system is
- Site rules, permits and inductions
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before we start, so there are no surprises.
Helping us quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Close-ups of filters, grilles, hatches or access panels
- The site address and the type of premises
- Any symptoms, from odd noises to smells or leaks
- 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. Add the site type and your opening hours, and many jobs can be priced from that alone.
New Malden kitchens: local notes
Food Standards Agency records list about 11 food manufacturers and packers across New Malden and its immediate surroundings (about a mile and a half). Food production can send a lot of fat, oil and grease towards the drains, so traps and interceptors need emptying on a schedule. Most London kitchens can’t close in the day, so deep cleaning is usually done overnight. Environmental health officers from Kingston-Upon-Thames council inspect food businesses in New Malden. An inspection covers the structure of the kitchen as well as the food. Keeping a record of deep cleans and grease trap visits helps at inspection time.
Half-term is a good time for school kitchens, at schools like Christ Church New Malden CofE Primary School for instance, to have the grease trap emptied and the kitchen deep cleaned. If you run catering at a healthcare site, such as a hospital like Kingston Hospital about 1.2 miles north-west, deep cleans and grease trap visits are planned so meals still go out.

What staff can safely do
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, which is where we come in.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
For landlords and multi-site operators
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Looking after it afterwards
Simple habits between visits make a real difference. We recommend:
- Mention any increase in cooking
- Collect waste cooking oil separately
- Book trap cleans at a set interval
- Don’t rely on hot water to clear grease
The sinks are ready to use as soon as we’ve finished. We run water through to check it drains before we leave.
If the kitchen has got busier, the trap fills faster. Booking cleans more often stops it overflowing.
