Grease trap cleaning for kitchens and businesses in Harwell
For kitchens across Harwell, grease trap cleaning fits easily around service. The trap is emptied, cleaned and checked, and the waste is taken away. It can be booked on its own or alongside other kitchen work. The work covers under-sink grease traps, inline grease traps and school and care home kitchens, and common reasons people get in touch are drains that gurgle and bubble and a larger grease trap that needs emptying.
For a kitchen near Harwell, deep cleans are booked around opening hours, often on a closed day, and the journey is planned ahead.
The paperwork matters as much as the work. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Harwell: your questions answered
Who would carry out a food hygiene inspection at a kitchen in Harwell?
The local authority for Harwell is Vale of White Horse council, and its environmental health team does the inspecting. Keep the dates of your last deep clean and grease trap visit with your food safety records, ready if an officer asks.
Can you come to Harwell after we close?
Yes. We work evenings, overnight and at weekends. That way a site in Harwell does not have to lose a day’s trading. When you call us on 0345 646 2711, or email photos, 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 long will the sinks be out of use?
Each trap is a little different, but a clean generally takes a short visit for a small trap and longer for an inline unit or interceptor. We’ll confirm when we quote.
What does a grease trap clean cost?
We price it once we know the trap and how often it needs cleaning. Get in touch and we will give you a fixed quote so you know the cost up front.
Will I get paperwork for my records?
Yes, on every job. The report is dated and includes pictures, and TR19® Grease cleans come with a certificate through the BESCA VHE portal. Keep it in your maintenance log.
Is TR19 a legal requirement?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. 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.
How often should a grease trap be cleaned?
It varies with the trap and the kitchen. If the sinks start to drain slowly between cleans, it’s too long and we’ll adjust the schedule.
In-house cleaning or a specialist?
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Landlords, agents and facilities managers
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
What affects the cost of grease trap cleaning
We don’t publish a price list, because no two systems are the same. The quote depends on:
- What state the system is in
- Access, including roofs, risers and ceiling voids
- Any permits to work or inductions
- Travel, parking and unloading
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.
What to send for a quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- The postcode and the type of business
- The paperwork from the last visit, if you have it
- Detail shots of panels, filters and grilles
- The times we could work without disrupting the site
To help us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Then call us on 0345 646 2711 or email us.
What happens on the day
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes less than an hour for many under-sink units. Visits to a place like Harwell are planned ahead, so we arrive with what the survey says the job needs.
- First, we locate the grease trap and look at the pipework around it.
- Nothing drains into the trap while it’s open.
- Built-up fat, oil and grease is removed from the trap.
- Every part of the trap is scraped and cleaned, including the baffles.
- Once it’s refitted, water is run through to check it drains, and we take the waste with us.
How to prepare
- Arrange a key holder or contact on site
- Move anything stored near the system
- Agree a time when the area can be out of use

Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Collect waste cooking oil separately
- Keep access to the trap clear
- Tell us when sinks start draining slowly
- Keep the grease trap on a regular cleaning schedule
We will suggest when the trap should be cleaned again. It’s based on how full it was and how busy the kitchen is.
A trap that is left too long stops catching grease. Regular emptying keeps it working and avoids a blockage.
What grease trap cleaning cannot fix
In fairness, there are a few things this work will not fix:
- Leaking pipework or sink wastes, which need a plumber
- A unit that cannot cope with the kitchen’s output
- Blockages further down the drainage network
If you are not sure, just give us a ring on 0345 646 2711 or send us an email and we will give you a straight answer before you book.
