St James's grease trap cleaning
Grease trap cleaning in St James's from ventilation hygiene specialists trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Drains clogged with fat

Leave it or put it right?
Smells from a neglected trap are hard to ignore. Rotting food and grease give off foul odours that can reach the kitchen and beyond. Cleaning it removes the cause. Leaving it on a busy London site only adds to the work.
The cost depends on the size of the system, what state it’s in and access to every part of it. We give you a fixed price before any work starts, so you know where you stand.

How we handle grease trap cleaning in St James's
Every trap is different. Under-sink traps are compact and need frequent attention and larger traps hold more grease before they fill. We look at the trap, how much the kitchen uses it and how quickly it fills before suggesting how often it needs cleaning. The work covers inline grease traps, under-sink grease traps and school and care home kitchens, and people most often call us about a routine grease trap service and a slow-draining kitchen sink.
Fat, oil and grease poured down drains helps form fatbergs, and London’s sewers have made the news for them more than once. A grease trap that’s emptied and cleaned regularly keeps fat out of the drains.
We have been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

St James's kitchens: local notes
The FSA’s food hygiene register includes about 366 pubs, bars and clubs and about 246 hotels and B&Bs in St James's and the streets around it, up to about 1.5 miles out. Pub and hotel kitchens get the same build-up behind equipment and in the grease trap as any other. Compact London kitchens collect grease in tight corners, which an overnight deep clean can reach. Food hygiene inspections in St James's are the job of Westminster council’s environmental health team. Grease behind equipment or on a ceiling is the kind of thing an inspection can note. Photos and dates from each deep clean make a useful record.
Hall and church kitchens, near St James’s Church or anywhere around St James's, are used by many hands, and periodic deep cleans and grease trap visits keep them in order. If you run catering at a healthcare site, such as a hospital like St James Workhouse about within half a mile north-west, deep cleans and grease trap visits are planned so meals still go out.

Multi-site and managed buildings
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
In-house cleaning or a specialist?
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Aftercare tips
A little care between visits keeps the system in better shape. We recommend:
- Make sure the trap can be reached easily
- Use strainers in the sink plugholes
- Mention any increase in cooking
- Do not wait for a blockage to book a clean
We’ll suggest when the trap should be cleaned again. It’s based on how full it was and how busy the kitchen is.
Grease that gets past the trap sets in the drains. Clearing it then is a bigger job, so it’s far better to keep the trap clean.
How the visit works
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, and that takes a short visit for a small trap and longer for an inline unit or interceptor. Night and weekend working is normal for us in London, and a site in St James's is no exception.
- We agree a time when the sinks aren’t needed.
- We open the trap and look at its condition.
- We remove the grease layer and settled solids.
- The inside, baffles and outlet are cleaned.
- We close it up, check it drains and suggest when it needs cleaning again.
Before we arrive
- Arrange a key holder or contact on site
- Tell us where we can park and unload
- Let us know when the site is closed or quiet

Advice
Questions from St James's
Can you work in school kitchens in St James's during the holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 94 schools, colleges and universities with registered kitchens within about a mile and a half of St James's. Tell us your holiday dates and we will book the visit for when the site is empty.
Who would carry out a food hygiene inspection at a kitchen in St James's?
That is Westminster council, whose environmental health officers carry out food hygiene inspections in St James's. An officer may look behind equipment and at drains, so it pays to have the deep clean booked before those areas build up.
What do you do to protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Can you give me a price for grease trap cleaning?
It depends on the type and size of the trap, its condition and access. Tell us about the trap and we’ll come back with a fixed price.
Where does the waste go?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it does not spread.
What types of premises do you cover?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
Do the sinks have to be out of use during the clean?
For the length of the clean, yes. It takes a short visit for a small trap and longer for an inline unit or interceptor, and we time it to suit you.
Which records should we keep?
Visit reports, certificates and your in-house cleaning logs. They’re what an insurer, fire officer or EHO may ask for, so keep them where they can be found quickly.
When it’s something else
We’ll always give you a straight diagnosis, so here’s what grease trap cleaning won’t do:
- Blockages in the public sewer beyond the property
- Collapsed or damaged drains, which need a drainage contractor
- Drains that need jetting rather than trap cleaning
Not sure which it is? You can call us on 0345 646 2711 or use the quote form and we’ll tell you honestly.
Where we work
- School and care home kitchens
- Pot wash sinks
- Restaurants and takeaways
- Kitchen waste pipes

- Under-sink grease traps
When to call us in St James's
A busy kitchen in St James's, or anywhere else, fills its grease trap faster. A trap that suited a quieter kitchen can struggle when cooking increases.
Common reasons sites call us include:
- A full, neglected grease trap
- Gurgling drains in the kitchen
- A larger grease trap that needs emptying
- Washing-up water that won’t drain away
If you run a kitchen near London Charing Cross station with long trading hours, grease builds up faster behind equipment and in the trap.
