About our grease trap cleaning in Belsize
A grease trap is the kitchen drain’s first line of protection. When it’s looked after, you hardly know it’s there, but neglected, it causes blockages and smells. Routine cleaning keeps it in good working order. We are often asked to deal with an under-sink unit that needs regular emptying and washing-up water that won’t drain away, across under-sink grease traps, restaurants and takeaways and kitchen waste pipes.
In rural areas, a kitchen may drain to a private system rather than a public sewer, so keeping fat out with a working grease trap matters even more.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What staff can safely do
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
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.
What affects the cost of grease trap cleaning
The survey tells us what the work involves. We look at:
- Parking and loading at the site
- Site rules, permits and inductions
- What state the system is in
- The times the site is available
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before work begins.
What we need to know
Photos let us diagnose from a distance. The most useful are:
- Photos showing the whole system and its surroundings
- The roof, plant room or outside wall the system runs to
- Detail shots of panels, filters and grilles
- Problems your staff have spotted
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.
Belsize: your questions answered
Can you come to Belsize after we close?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Your opening times are the first thing we ask for.
Can you get to a site in Belsize?
Yes, we work in villages as well as towns, and Belsize is covered. A survey first, from photos or a visit, means we arrive with the right kit.
How much time does a grease trap clean need?
Typically, it takes an hour or so for an under-sink trap, longer for a larger unit. Bigger or overdue traps need more time and we will say so when we quote.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
Do you have insurance?
Yes. Full insurance covers our work, and we have been trading since 2009.
Can you clear our blocked drains as well?
It depends where the blockage is. A full trap is a common cause, and cleaning it can help, but blockages further along need a drainage contractor.
Will I get paperwork for my records?
Yes. It’s your proof that the work was done: a written, dated record with photos of what we did and anything we couldn’t access.
Which grease traps does the service cover?
We clean all the common types. A photo helps us see what’s fitted when you call 0345 646 2711 or send us an email.
Landlords, agents and facilities managers
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
Part by part
School, care home and staff kitchens
Kitchens with fixed mealtimes build up grease more predictably. Planned cleaning fits their routine.
Baffles and outlets
Every clean includes the baffles, inlet and outlet so water flows freely.
What grease trap cleaning looks like in Belsize
Look up Belsize on the FSA’s food hygiene register and you will find about 7 restaurants, cafés and canteens within about 1.5 miles of central Belsize. Kitchens like these wash fat, oil and grease down the sink every day, and a grease trap is what stops it reaching the sewer. In Belsize, food businesses are inspected by environmental health officers from Three Rivers council. Grease behind equipment or on a ceiling is the kind of thing an inspection can note. Keeping a record of deep cleans and grease trap visits helps at inspection time.
Hemel Hempstead Hospital, about 4 miles north, is the nearest hospital to Belsize; healthcare kitchens cannot stop cooking, so deep cleans are worked around meal times. A summer deep clean suits schools such as Sarratt Church of England Primary School, as the kitchen can be stripped back with no lunches to serve. Where a church or community hall near Church of St Paul, or anywhere in Belsize, has a kitchen used by volunteers, a periodic deep clean keeps it ready for the next event.

Advice
Between visits
Aftercare is simple, and it makes the next visit easier:
- Tell us if your menu or hours change
- Tell us when sinks start draining slowly
- Book trap cleans at a set interval
- Don’t rely on hot water to clear grease
The waste we remove leaves with us. Nothing is left for you to dispose of after the visit.
An overfull trap lets grease pass. Cleaning it before it’s full keeps grease out of the drains and saves a call-out for a blocked drain.
