Why it’s worth doing now in St John's Wood
A dirty grease trap smells. Decomposing waste in the trap smells bad and the smell carries. A clean trap takes the source away. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, phone us on 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.

About our grease trap cleaning in St John's Wood
A clean trap means flowing drains and no foul smells. We empty the built-up grease and food solids and the chambers and baffles cleaned, and check the trap is working properly. Common call-outs are for an inline trap or interceptor due for cleaning and scheduled grease trap emptying, across pot wash sinks, restaurants and takeaways and under-sink grease traps.
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 St John's Wood from adding to the problem.
We’ve been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

FAQs for St John's Wood
Who inspects food businesses in St John's Wood?
Food hygiene inspections in St John's Wood are carried out by Camden council. 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.
Do you work overnight in St John's Wood?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in St John's Wood needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Do we lose a day’s trading?
Not normally. The area we are working in has to be out of use while we are there, so the visit goes in a quiet slot.
Is TR19 a legal requirement?
No, not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, 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.
Who is responsible for fire safety on the premises?
The Fire Safety Order 2005 calls them the responsible person: normally the employer or whoever controls the premises. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
Will you tell us when the next visit is due?
Yes. The recommended date is on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, while fire dampers are tested at least annually.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What do you do with what you remove?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it does not spread.
Fixed quotes for grease trap cleaning in St John's Wood
We quote each job individually. These are the things that affect it:
- How many systems or sites are involved
- Any permits to work or inductions
- Where the site is and how we reach it
- The size of the system
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before any work starts.
Asking for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- A few general shots of the system
- The paperwork from the last visit, if you have it
Getting a quote does not take long. Send a few details and photos, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
In-house cleaning or a specialist?
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.
Day-to-day cleaning is something your team can do: 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.

Related advice
Part by part
School, care home and staff kitchens
Kitchens that serve set mealtimes fill their traps more steadily. A regular interval suits them well.
Grease interceptors
Grease interceptors are larger units that serve busier kitchens. They hold more grease and solids but they still need cleaning.
Signs you need grease trap cleaning in St John's Wood
Hot washing-up water keeps grease liquid for a while. Once it cools, it sets in the pipework or the drain.
Keep an eye out for these warning signs:
- A full, neglected grease trap
- An under-sink unit that needs regular emptying
- An interceptor full of grease and solids
- Scheduled grease trap emptying
Hall kitchens near Church of All Souls or elsewhere in St John's Wood may have older sinks and drains, so a grease trap check is worth adding to a deep clean.
