Grease trap cleaning in Cotman's Ash, done properly
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 foul odours from the grease trap and grease setting in the kitchen pipework, on inline grease traps, school and care home kitchens and pot wash sinks.
In a village or hamlet like Cotman's Ash, commercial kitchens are few, perhaps a pub, a school or a care home. Each still needs the occasional deep clean and its grease trap kept clear.
Every visit ends with a written report and photos, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What the work involves, part by part
Inline grease traps
Inline traps often take waste from several sinks or appliances. More waste means faster filling.
School, care home and staff kitchens
Drains in care settings need to keep flowing. We fit visits around mealtimes.
How the visit works
Your staff do not need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. If the van will struggle with a lane or gateway near Cotman's Ash, let us know and we’ll plan around it.
- First, we locate the grease trap and look at the pipework around it.
- The sinks feeding the trap are kept out of use while we work.
- The trap is emptied of grease and food waste.
- Every part of the trap is scraped and cleaned, including the baffles.
- We put it back together, run water through and remove the waste.
Getting ready for the visit
- Mention any locked doors, roof access or ceiling voids
- Clear the space around the work
- Make sure someone can let us in and lock up afterwards

Why it’s worth doing now in Cotman's Ash
Pouring hot water or chemicals down a slow drain is a common quick fix. That only moves the grease further down the pipe to set somewhere harder to reach. The lasting fix starts with the trap. Equipment tucked in a roof space or outbuilding near Cotman's Ash rarely gets looked at unless someone books it.
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.

When to call us in Cotman's Ash
A full trap cannot hold any more grease. It goes on into the drain and on towards the sewer, where it can form blockages.
Common reasons sites call us are:
- An under-sink unit that needs regular emptying
- An interceptor full of grease and solids
- A kitchen drain that smells
- A routine grease trap service
School kitchens, at schools like Kemsing Primary School for example, typically have their deep cleans and grease trap work done while the canteen is closed.
Questions to ask before you book
- What hours they’ll be on site
- Whether a written report and photos are included
- Proof of insurance
- Which accreditations they hold, and whether you can check them
What staff can safely do
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.

Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.
Does the report say when we need you again?
Yes. We put a recommended next date on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, and fire dampers need testing at least once a year.

Each trap is a little different, and you can expect it to take an hour or two in most kitchens, depending on the size and condition of the trap. We will confirm when we quote.
What does a grease trap clean cost?
It depends on the type and size of the trap, its condition and access. Tell us about the trap and we will come back with a fixed price.
What’s the right interval for grease trap cleaning?
It depends on the size of the trap and how busy the kitchen is. A small trap fills more quickly than a large one and the busier the kitchen, the faster it fills. We will suggest an interval after the first clean.
