About our grease trap cleaning in Cranford
If the sinks drain slowly or smell, the trap is often the cause. We find the trap, empty it and clean it, then check the water flows properly. We are often asked to deal with a bad smell from the sinks or drains and grease setting in the kitchen pipework, across school and care home kitchens, inline grease traps and pot wash sinks.
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 Cranford 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 carry full insurance.

How we price grease trap cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- Where the site is and how we reach it
- How big the system is
- How many systems or sites are involved
- Whether we need access equipment or extra panels
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before any work starts.
Helping us quote
When you call or email, these details help:
- Your opening hours and when the area is out of use
- The site address and the type of premises
- How we’d reach plant on a roof or in a plant room
- Close-ups of filters, grilles, hatches or access panels

How the job changes from site to site
Inline grease traps
Inline traps are fitted into the drain line. They hold more than under-sink units but still fill up.
School, care home and staff kitchens
Kitchens with fixed mealtimes build up grease more predictably. Planned cleaning fits their routine.
How the visit works
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. The middle part takes longest, which takes an hour or two in most kitchens, depending on the size and condition of the trap. Before any visit in Cranford, we agree where the van can stop and how equipment reaches the system.
- We start by finding the trap and checking its inlet and outlet.
- The sinks feeding the trap are kept out of use while we work.
- The trap is emptied of grease and food waste.
- The inside, baffles and pipe connections are cleaned.
- We put it back together, run water through and remove the waste.
Before we arrive
- Have your last certificate or report to hand
- Move anything stored near the system
- Mention any locked doors, roof access or ceiling voids
How to get a quote
Every quote begins with a look at the system, 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 we start.

Cranford kitchens: local notes
Look up Cranford on the FSA’s food hygiene register and you will find about 8 food manufacturers and packers in and around Cranford, up to about a mile and a half out. Food production can send a lot of fat, oil and grease towards the drains, so traps and interceptors need emptying on a schedule. In London, deep cleans and grease trap work are usually done overnight, so the kitchen opens as normal the next day. Food hygiene inspections in Cranford are the job of Hounslow council’s environmental health team. The state of floors, drains and hard-to-reach corners all feeds into the inspection. Having the dates of the last deep clean to hand saves digging for them on the day.
Healthcare kitchens, like those at hospitals such as Hounslow Hospital (about 1.6 miles east), cook for long hours, so deep cleans and grease trap work are planned around patients’ meals. If you look after a hall kitchen near The Parish Church of the Good Shepherd or anywhere in Cranford, a deep clean between busy seasons is easier than a scramble before a big event.

When to call us in Cranford
In Cranford, as everywhere, grease traps are easy to forget. Tucked away under the sink or below the floor it’s often left until there’s a problem.
These are the problems we see most often:
- A larger grease trap that needs emptying
- A bad smell from the sinks or drains
- A slow-draining kitchen sink
- Gurgling drains in the kitchen
School kitchens, at schools like Cranford Primary School for example, usually have their deep cleans and grease trap work done while the canteen is closed.
What to look for in a quote
- When they can work, and whether that is outside your opening hours
- Whether a survey comes first
- Whether the figure could change on the day
- Whether they’re fully insured
Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Wipe grease off pans before washing them
- Make sure the trap can be reached easily
- Keep waste oil out of the drains
- Fit sink strainers to catch food scraps
We take the grease and solids away. Nothing is left for you to dispose of after the visit.
Fat that escapes the trap hardens in the pipework. Once it’s there, it needs a drainage contractor to clear so prevention is the easier route.
Why it’s worth doing now in Cranford
Some kitchens try to fix slow drains with hot water or drain cleaners. It just shifts the grease further along, where it sets again. Emptying and cleaning the trap deals with the source. In Cranford, a planned overnight visit is much easier than closing unexpectedly.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, give us a ring on 0345 646 2711 or send us an email for straight advice and a fixed quote.

In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Your questions about grease trap cleaning in Cranford
Do you work in school kitchens around Cranford out of term?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 22 schools, colleges and universities with registered kitchens within about a mile and a half of Cranford. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Is parking a problem for work in Cranford?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.
What’s the right interval for grease trap cleaning?
That depends on the trap and the kitchen. A small trap fills more quickly than a large one and the busier the kitchen, the faster it fills. We’ll suggest an interval after the first clean.
Are you insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
What happens if a grease trap isn’t cleaned?
An overfull trap stops separating grease. Slow drains, bad smells and blockages follow.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
