Grease trap cleaning in Denchworth
Grease trap cleaning keeps the drains running and the smells away. The fat, oil, grease and solids are taken out, clean the inside and the baffles, and check the trap is working properly. The work covers kitchen waste pipes, under-sink grease traps and restaurants and takeaways, and common reasons people get in touch are sinks that drain slowly and an inline trap or interceptor due for cleaning.
Rural kitchens may drain to a septic tank or a private drain rather than straight into a public sewer, and fat getting past a grease trap can cause real trouble there.

Denchworth kitchens: local notes
There are about 3 restaurants, cafés and works canteens and about 3 takeaways and sandwich shops within roughly a mile and a half of the centre of Denchworth, according to the Food Standards Agency’s register. Kitchens like these wash fat, oil and grease down the sink every day, and a grease trap is what stops it reaching the sewer. Food hygiene inspections in Denchworth are the job of Vale of White Horse council’s environmental health team. An inspection covers the structure of the kitchen as well as the food. A cleaning log that includes deep cleans and grease trap visits shows the work is planned. Denchworth is about 59 miles from central London, well within the area we cover across London and the South East. Visits are booked around your hours, evenings and weekends included.
Hall and church kitchens, near Church of St James or anywhere around Denchworth, are used by many hands, and periodic deep cleans and grease trap visits keep them in order. If you run event catering at a historic house or estate in the area (Longworth House is about 4.7 miles north), a deep clean before or after the busy season is worth planning.

Multi-site and managed buildings

We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
How we price grease trap cleaning
We quote each job individually. These are the things that affect it:
- Travel, parking and unloading
- Site requirements such as sign-in and permits
- Whether we need access equipment or extra panels
- When the work can happen, such as evenings, overnight or weekends
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You will have a fixed price before we start.
Asking for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Close-ups of filters, grilles, hatches or access panels
- Any symptoms, from odd noises to smells or leaks
- Your opening hours and when the area is out of use
- How we’d reach plant on a roof or in a plant room
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, and then send you a fixed quote. To get going, give us a ring on 0345 646 2711 or send us an email.
Aftercare tips
So the system stays in good health:
- Wipe grease off pans before washing them
- Use strainers in the sink plugholes
- Tell us if your menu or hours change
- Make sure the trap can be reached easily
Collect waste cooking oil separately rather than pouring it down the sink and the trap won’t fill as quickly. It makes a real difference.
If the sinks are slow or smelly, the trap may be full. Acting at this stage normally prevents a blockage down the line.
In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
In-house cleaning and specialist cleaning do different jobs. 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. Reaching it takes a specialist with the right equipment.

Other services in Denchworth
Different parts, different methods
School, care home and staff kitchens
In schools, grease traps can be cleaned when the kitchen is closed or after lunch service.
Baffles and outlets
Baffles inside the trap slow the water so grease can separate. Grease clings to them so they’re cleaned every time.
Denchworth: your questions answered
Do you work at weekends in Denchworth?
Yes, we can come after you close and finish before you open. The work in Denchworth can fit around your hours. Your opening times are the first thing we ask for.
Can a school kitchen in Denchworth be done out of term time?
Yes, out-of-term visits are normal for schools. Around Denchworth, the Food Standards Agency lists about 3 schools and colleges with registered kitchens within a mile and a half or so. You can call 0345 646 2711, or email photos with the dates the site is empty.
How often should a grease trap be cleaned?
There’s no single answer. We look at how full the trap is and how quickly it fills, then suggest a schedule.
Where does the grease from the trap go?
We take the grease and solids away with us. You are not left with anything to dispose of after the visit.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
What happens if a grease trap is not cleaned?
Once it’s full, grease passes straight through. It then sets in the drains, causing blockages and smells and can end up adding to sewer blockages.
Are you fully insured?
Yes. We’re fully insured, and we can share the details when you need them.
Do you survey before quoting?
Yes. Photos often do the job, and larger or hidden systems get a visit.
When it’s something else
To be straight with you, some problems need a different fix:
- Drains that need jetting rather than trap cleaning
- Leaking pipework or sink wastes, which need a plumber
- A trap undersized for the amount of cooking
If in doubt, ring 0345 646 2711 or drop us a line and we will say what we think before you book.

What we do, step by step
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes a short visit for a small trap and longer for an inline unit or interceptor. In a small place like Denchworth, the journey is planned ahead and the visit arranged around the site’s hours.
- We agree a time when the sinks aren’t needed.
- The trap is opened up and checked.
- We remove the grease layer and settled solids.
- The inside, baffles and outlet are cleaned.
- We close it up, check it drains and suggest when it needs cleaning again.
Before we arrive
- Let us know about permits to work or site inductions
- Clear loose items from the work area
