How we price grease trap cleaning
Every site gets its own quote. These are the things that affect it:
- A single visit or a regular plan
- Any permits to work or inductions
- What state the system is in
- Parking and loading at the site
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
What to send for a quote
To help us quote quickly, send us:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any access panels or hatches you can see
- The site address and the type of premises
- When the site is open and when it’s quiet
For a fixed quote, give us a ring on 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You will typically have a quote within one working day.
Grease trap cleaning for kitchens and businesses in Belsize Park
A clean trap means flowing drains and no foul smells. We empty the built-up grease and food solids, clean the inside and the baffles, and check the trap is working properly. Common call-outs are for gurgling from the sink waste and a bad smell from the sinks or drains, on school and care home kitchens, pot wash sinks and restaurants and takeaways.
London’s sewers are known for fatbergs, built up from fat, oil and grease washed down drains. Regular grease trap cleaning keeps a kitchen in Belsize Park from adding to the problem.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Common questions in Belsize Park
What do you need to know about parking in Belsize Park?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, typically makes it simpler.
Do you clean school kitchens in Belsize Park in the summer holidays?
Yes. The holidays are the usual time for school work. Around Belsize Park, the Food Standards Agency lists about 71 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.
What do you do with the waste?
We remove all the waste we take out. It isn’t poured back down the drain at any point.
What problems does a full grease trap cause?
Once it’s full, grease passes straight through. The grease hardens in the pipes, leading to blocked drains and smells, and can add to fatbergs in the sewer.
Do you offer maintenance contracts?
Yes, of course. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
How much time does a grease trap clean need?
Most grease trap cleans take an hour or so for an under-sink trap, longer for a larger unit, including testing. It’s booked when the sinks aren’t needed.
Do you have a 24/7 line?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Do you deal with blocked drains beyond the grease trap?
It depends where the blockage is. A full trap is a common cause, and cleaning it can help but grease set further down the drains needs jetting by a drainage specialist.
In-house cleaning or a specialist?
Staff cleaning does not 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.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
How the visit works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes anything from under an hour to a few hours, depending on the trap. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Belsize Park.
- We find the trap and check how it’s connected.
- We ask for the sinks that drain into the trap not to be used.
- The trap is emptied of grease and food waste.
- The inside, baffles and pipe connections are cleaned.
- Once it’s refitted, water is run through to check it drains, and we take the waste with us.
How to prepare
- Clear loose items from the work area
- Let us know about parking and loading
- Tell us the best time to work, such as after service or at a weekend

Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.
Advice
What we’re called out for in Belsize Park
Waste cooking oil poured down the sink overloads the trap fast. Even small amounts add up.
It’s time to book a visit if you see:
- A blocked kitchen drain caused by grease
- A grease trap that hasn’t been emptied in a long time
- An under-sink trap that keeps filling up
- Gurgling from the sink waste
If you look after a school kitchen, at a school such as Fine Arts College or anywhere near Belsize Park, the holidays are the time for a deep clean or a grease trap clean.
Questions to ask before you book
- What’s included in the scope, part by part
- Whether the quote is based on a survey or photos
- Whether inaccessible sections are listed on the report
- What records you will receive afterwards
Keeping the system healthy
Aftercare is simple, and it makes the next visit easier:
- Scrape plates and pans into the bin before washing up
- Tell us if your menu or hours change
- Collect waste cooking oil separately
- Use strainers in the sink plugholes
Anything we notice beyond the trap, like a slow drain downstream, is pointed out. It may need a drainage specialist to look further.
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.
What the work involves, part by part
Restaurant and takeaway kitchens
Busy kitchens with lots of washing-up fill traps fast. A shorter cleaning interval typically suits them.
Under-sink grease traps
Under-sink units are easy to forget. A full one shows itself with a slow, smelly sink.
Why it’s worth doing now in Belsize Park
In Belsize Park, as anywhere, grease trap cleaning is a short, routine visit. Waiting for a blockage turns it into an urgent problem and typically at the worst moment. For a site in Belsize Park, fitting the work in overnight now is far easier than closing at short notice later.
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and why the quote is fixed before we start.

Grease trap cleaning in Belsize Park: local notes
Food Standards Agency data counts about 749 cafés, restaurants and staff canteens and about 325 takeaways in and around Belsize Park, up to about a mile and a half out. Each of them sends fat, oil and grease towards the drain, which is why grease traps need regular emptying. Environmental health officers from Camden council inspect food businesses in Belsize Park. An inspection covers the structure of the kitchen as well as the food. A cleaning log that includes deep cleans and grease trap visits shows the work is planned. Fat from London kitchens contributes to sewer blockages, which is why grease traps need emptying on a schedule.
For a café close to South Hampstead station, a deep clean can be done between closing and the morning rush. Healthcare kitchens cook through the year, so a deep clean has to be fitted around meals; Wellington Hospital, about 0.9 miles south-west, is the nearest hospital to Belsize Park.
