Grease trap cleaning for kitchens and businesses in Knatts Valley
Once a trap is full, grease passes straight through. Fat sets in the pipes downstream and the result is blocked drains and bad smells. Regular cleaning keeps it working. If you are dealing with an interceptor full of grease and solids and gurgling drains in the kitchen, we can put it right.
Work in a small place like Knatts Valley starts with agreeing a date and access.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Knatts Valley questions
Can you come to Knatts Valley after we close?
Yes, out-of-hours work is a big part of what we do. That way a site in Knatts Valley doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
Is Knatts Valley within the area you cover?
Yes, Knatts Valley is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Where does the waste go?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Are you insured?
Yes. We’re fully insured, and we can share the details when you need them.
What types of premises do you cover?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
What does TR19 mean?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
Do you provide a certificate or report?
Yes, always. It’s a dated, written report with photos, and TR19® Grease cleans come with a certificate through the BESCA VHE portal. Keep it in your maintenance log.
What paperwork should we keep on file?
Visit reports, certificates and your in-house cleaning logs. They’re what an insurer, fire officer or EHO may ask for, so keep them where they can be found quickly.
What a clean will not put right
It’s worth knowing the limits before booking:
- Leaking pipework or sink wastes, which need a plumber
- Blockages further down the drainage network
- Drains that are cracked or have collapsed
Not sure which it is? You can call us on 0345 646 2711 or use the quote form and we will tell you honestly.
Parts of the system we cover
- Pot wash sinks
- Inline grease traps
- School and care home kitchens
- Under-sink grease traps
- Restaurants and takeaways
- Kitchen waste pipes
Do you need grease trap cleaning in Knatts Valley?
Waste cooking oil poured down the sink fills a grease trap far faster than washing-up. Small amounts soon build up.
It’s time to book a visit if you see:
- Scheduled grease trap emptying
- An inline trap or interceptor due for cleaning
- Gurgling drains in the kitchen
- A kitchen drain that smells
If you cater for weddings or events at a historic house in the area (Lullingstone Castle is about 2.8 miles north-west), deep cleans can be fitted between bookings.
Before booking anyone
- If the quote is a fixed price or an estimate
- If they look at the system before pricing
- Whether the work can be done while the site is closed
- How they set the interval to the next visit
Looking after it afterwards
A little care between visits keeps the system in better shape. Our advice:
- Wipe grease off pans before washing them
- Don’t rely on hot water to clear grease
- Keep access to the trap clear
- Do not wait for a blockage to book a clean
Scrape plates into the bin before washing up. Sink strainers help catch solids so less solid waste gets through.
A trap that is left too long stops catching grease. Regular emptying keeps it working and avoids a blockage.
Knatts Valley kitchens: local notes
The FSA’s data shows about 3 bars, pubs and nightclubs registered within about 1.5 miles of central Knatts Valley. Pub and hotel kitchens get the same build-up behind equipment and in the grease trap as any other. It’s Sevenoaks council that sends environmental health officers to food businesses in Knatts Valley. Walls, floors, ceilings and equipment are all part of what they look at. A cleaning log that includes deep cleans and grease trap visits shows the work is planned.
School kitchens, at schools like West Kingsdown CofE VC Primary School for example, typically have their deep cleans and grease trap work done while the canteen is closed. If you run a care home or healthcare kitchen near Knatts Valley (the nearest hospital is Sevenoaks Hospital, about 3.9 miles south-west), a grease trap on a set schedule avoids a blocked drain mid-service.

How we price grease trap cleaning
We don’t publish a price list, because no two systems are the same. The quote depends on:
- Travel, parking and unloading
- What state the system is in
- The times the site is available
- The size of the system
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before we start, so there are no surprises.
What to send for a quote
We can often survey from photos. The most useful are:
- The site address and the type of premises
- Your opening hours and when the area is out of use
- The paperwork from the last visit, if you have it
- Problems your staff have spotted
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
How the visit works
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes anything from under an hour to a few hours, depending on the trap. Seeing the system in photos first means the trip to Knatts Valley can be planned properly.
- We locate the trap and check how it’s fitted.
- Sinks feeding the trap are taken out of use.
- Grease and solids are removed from the trap.
- The chambers and baffles are cleaned.
- We refit it, run water through and remove the waste.
Getting ready for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Find the previous report, if there is one
- Let us know when the site is closed or quiet
Getting a quote
We do not publish a price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To start, call us on 0345 646 2711 or use the quote form.

What your team can do, and what needs us
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and 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.
