About our grease trap cleaning in Underriver
Smells from the sink, gurgling drains or slow drainage all point to the grease trap. In Underriver, as everywhere we work, our team empties and cleans the trap and run water through to check it drains. The work covers school and care home kitchens, pot wash sinks and restaurants and takeaways, and common reasons people get in touch are an inline trap or interceptor due for cleaning and a routine grease trap service.
In a village or hamlet like Underriver, commercial kitchens are few, perhaps a pub, a school or a care home. Wherever there is one, it needs its grease trap and hard-to-reach areas kept clean.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Do you need grease trap cleaning in Underriver?
Fats, oils and grease from cooking and washing up go down the sink. In the trap, they cool and separate and the grease layer grows.
Signs it’s time to call us include:
- Scheduled grease trap emptying
- A bad smell from the sinks or drains
- An overdue grease trap
- An under-sink unit that needs regular emptying
A summer deep clean suits schools such as Sevenoaks Preparatory School, as the kitchen can be stripped back with no lunches to serve.

What we do, step by step
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit takes a short visit for a small trap and longer for an inline unit or interceptor. In a small place like Underriver, the journey is planned ahead and the visit arranged around the site’s hours.
- We locate the trap and check how it’s fitted.
- Sinks feeding the trap are taken out of use.
- We empty out the fat, oil, grease and solids.
- The chambers and baffles are cleaned.
- The trap is refitted, tested with water and the waste taken away.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Let us know when the site is closed or quiet
- Let us know about parking and loading

What affects the quote in Underriver
Before we fix a price, we need to know a few things. We check:
- A single visit or a regular plan
- Working hours and out-of-hours timing
- Whether several sites go on one quote
- How big the system is
What you pay reflects the actual work. That is why we survey first, from photos or on site, and the price is agreed before work begins.
What we need to know
When you contact us, these details help:
- Your last certificate, test record or report
- How we’d reach plant on a roof or in a plant room
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Detail shots of panels, filters and grilles
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, call 0345 646 2711, or email photos.
What happens if it’s left?
Smells from a neglected trap are hard to ignore. Rotting food and grease give off foul odours that can reach the kitchen and beyond. Cleaning it removes the cause. With notice, the visit to Underriver can be fitted around your bookings and events.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.

Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Keep waste oil out of the drains
- Keep the grease trap on a regular cleaning schedule
- Tell us if your menu or hours change
- Get food waste into the bin, not the sink
The sinks are ready to use as soon as we’ve finished. We run water through to check it drains before we leave.
Slow sinks and a bad smell are early warnings. Getting it cleaned now can stop a full blockage later.
Part by part
Grease interceptors
Grease interceptors are larger units that serve busier kitchens. They hold more grease and solids, but they still need regular emptying and cleaning.
Restaurant and takeaway kitchens
Busy kitchens can’t afford a blocked drain. Regular trap cleaning helps prevent it.
Questions from Underriver
Do you work in villages like Underriver?
Yes, Underriver is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.
Can you work in Underriver outside opening hours?
Yes, evening, overnight and weekend work is normal for us. That way a site in Underriver doesn’t have to lose a day’s trading. When you call 0345 646 2711 or send us an email, mention when the site is quiet.
Is there a survey before the work?
Yes. We always survey first, from your pictures and details, or with a visit where needed. Then you get a fixed quote.
What accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Can you clear our blocked drains as well?
It depends where the blockage is. If the trap is full, cleaning it often helps but grease set further down the drains needs jetting by a drainage specialist.
Are you insured?
Yes. Full insurance covers our work and have been trading since 2009.
Do you recommend a next date?
Yes. The report recommends when the next visit should be, based on use and what we found.
Do we need to close while you work?
Not usually. The area we are working in has to be out of use while we are there, so we book a time when it would be closed anyway.
