Grease trap cleaning in Westmill, done properly
Smells from the sink, gurgling drains or slow drainage all point to the grease trap. We find the trap, empty it and clean it and run water through to check it drains. If you’re dealing with drains that gurgle and bubble and an inline trap or interceptor due for cleaning, we can help.
For a kitchen in or near Westmill, the visit is planned ahead, around opening times and the journey.

Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
Why deal with it now?
Pests are drawn to grease and food waste. A clean trap is less of an attraction as part of a clean kitchen. If the system at a site near Westmill fails, there may be nowhere nearby to move to.
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.

Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Get food waste into the bin, not the sink
- Fit sink strainers to catch food scraps
- Book trap cleans at a set interval
- Keep access to the trap clear
Scrape plates into the bin before washing up. Sink strainers help catch solids before they reach the trap.
Grease that gets past the trap sets in the drains. Once it’s there, it needs a drainage contractor to clear, so it’s far better to keep the trap clean.
Westmill questions
Can a school kitchen in Westmill be done out of term time?
Yes, and it’s the easiest time to do it. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Westmill. Just phone us on 0345 646 2711, or send details by email with your term dates and we’ll plan around them.
Do you work overnight in Westmill?
Yes, nights and weekends are routine for us. It means the site in Westmill keeps running as normal. When you call 0345 646 2711 or use the quote form, mention when the site is quiet.
Do we lose a day’s trading?
Not normally. Visits are timed for when the area is closed, such as overnight or at a weekend, so you keep your normal hours.
How do you protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
How much notice do you need?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
Do you deal with blocked drains beyond the grease trap?
We clean the trap, not the drain network. Where the problem is further down the drain, we’ll say so so you can call a drainage contractor.
Is TR19 a legal requirement?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
Are you fully insured?
Yes. We carry full insurance and have been trading since 2009.
Signs you need grease trap cleaning in Westmill
Food waste slips past sink strainers or gets rinsed down. It settles in the trap as solids and fill it from below.
These are the problems we see most often:
- Grease setting in the kitchen pipework
- An inline trap or interceptor due for cleaning
- A regular cleaning plan for the grease trap
- An under-sink unit that needs regular emptying
Hall and church kitchens, near Parish Church of St Mary the Virgin or anywhere around Westmill, are used by many hands, and periodic deep cleans and grease trap visits keep them in order.

What else we do in Westmill
What your team can do, and what needs us
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
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.
How the job changes from site to site
Grease interceptors
Interceptors take longer to clean and we allow for that.
Inline grease traps
Inline traps are fitted into the drain line. They’re larger than under-sink traps but still need regular emptying.
How the visit works
Each visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, do the work, clear away and leave you the report. The visit itself takes an hour or so for an under-sink trap, longer for a larger unit. In a small place like Westmill, the journey is planned ahead and the visit arranged around the site’s hours.
- 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.
- We clean the chambers, baffles and connections.
- The trap is reassembled, checked for leaks and the waste taken away.
How to prepare
- Make sure someone can let us in and lock up afterwards
- Have your last certificate or report to hand
- Clear the space around the work
