- An under-sink unit that needs regular emptying
Aftercare tips
Looking after the system between visits is straightforward, and it helps at the next visit:
- Book trap cleans at a set interval
- Make sure the trap can be reached easily
- Wipe grease off pans before washing them
- Never pour used oil down the sink
Scrape plates into the bin before washing up. Use strainers in the sink plugholes before they reach the trap.
More cooking means more grease in the trap. Shortening the cleaning interval now keeps the drains flowing.
Grease trap cleaning in Crooked Billet
Smells from the sink, gurgling drains or slow drainage all point to the grease trap. We find the trap, empty it and clean it and run water through to check it drains. The work covers restaurants and takeaways, under-sink grease traps and inline grease traps, and the jobs we see most are an inline trap or interceptor due for cleaning and drains clogged with fat.
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 Crooked Billet get in touch.
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.

What staff can safely do
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
The process
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before any work starts, and floors and nearby surfaces are sheeted. On site, it takes less than an hour for many under-sink units. Night and weekend working is normal for us in London, and a site in Crooked Billet is no exception.
- We agree a time when the sinks are not needed.
- The trap is opened up and checked.
- We remove the grease layer and settled solids.
- We clean the baffles, inlet and outlet.
- We close it up, check it drains and suggest when it needs cleaning again.
Preparing for the visit
- Let us know about permits to work or site inductions
- Let us know how we reach the system, including roofs, risers and plant rooms
- Find the previous report, if there is one
Getting a quote
Quotes are quick. Call or email with a few details and you will usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

What affects the cost of grease trap cleaning
Before we fix a price, we need to know a few things. We check:
- The size of the system
- When the work can happen, such as evenings, overnight or weekends
- Access, including roofs, risers and ceiling voids
- Where the site is and how we reach it
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before we start, so you know where you stand.
Helping us quote
Photos let us diagnose from a distance. Try to include:
- Any symptoms, from odd noises to smells or leaks
- A few general shots of the system
- Any previous report or certificate
- The postcode and the type of business
To get a fixed quote, ring 0345 646 2711 or email us with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You’ll normally have a quote within one working day.
For landlords and multi-site operators
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, 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.
Commercial kitchens in Crooked Billet
According to Food Standards Agency records, there are about 32 pubs and bars and about 6 hotels and guest houses within roughly a mile and a half of the centre of Crooked Billet. Wherever they cook, the kitchen and its drains need the same attention as a restaurant’s. Most London kitchens can’t close in the day, so deep cleaning is normally done overnight. Kitchens in Crooked Billet get their food hygiene inspections from Merton council. An inspection covers the structure of the kitchen as well as the food. Having the dates of the last deep clean to hand saves digging for them on the day.
Hall kitchens near Christ Church or elsewhere in Crooked Billet may have older sinks and drains, so a grease trap check is worth adding to a deep clean. A summer deep clean suits schools such as Wimbledon College, as the kitchen can be stripped back with no lunches to serve. If you serve passing trade near Raynes Park station, a grease trap on a regular schedule keeps the drains running through busy weeks.

Why deal with it now?

Crooked Billet questions
Which council inspects kitchens in Crooked Billet?
Kitchens in Crooked Billet are inspected by Merton council’s environmental health officers. An officer may look behind equipment and at drains, so it pays to have the deep clean booked before those areas build up.
Can you work in Crooked Billet outside opening hours?
Yes, nights and weekends are routine for us. It means the site in Crooked Billet keeps running as normal. Tell us your opening hours when you ask for a quote.
Can you clear our blocked drains as well?
It depends where the blockage is. If the trap is full, cleaning it often helps but grease set further down the drains needs jetting by a drainage specialist.
How long will the sinks be out of use?
The size and state of the trap make the difference, and you can expect it to take less than an hour for many under-sink units. We will confirm when we quote.
Is TR19 cleaning required by law?
No, not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurers ask for proof of cleaning to it. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005 in England and Wales.
Will we have to shut during the visit?
Not typically. Visits are timed for when the area is closed, such as overnight or at a weekend, so you keep your normal hours.
Who has the legal duty for fire safety?
That depends on who controls the premises. The Fire Safety Order 2005 puts the duty on the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and we will quote them together.
What a clean will not put right
Not every problem is solved by grease trap cleaning, and we’d rather say so up front. It will not put right:
- Sewer problems outside the premises
- Drains that need jetting rather than trap cleaning
- A grease trap that is too small for the kitchen
If in doubt, give us a ring on 0345 646 2711 or use the quote form and we’ll say what we think.
