Grease trap cleaning for kitchens and businesses in Riddlesdown
Grease is behind most blocked kitchen drains. Down the line, they can add to fatbergs in the sewer. A grease trap that is emptied and cleaned regularly holds them back. If you have a full, neglected grease trap and scheduled grease trap emptying, we can help, from school and care home kitchens, restaurants and takeaways and kitchen waste pipes onwards.
London kitchens work hard in small spaces, so grease collects behind equipment, on ceilings and in drains and grease traps. In Riddlesdown, deep cleans and grease trap work are usually done overnight.
The report is your system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

FAQs for Riddlesdown
Do you work in school kitchens around Riddlesdown out of term?
Yes, and it’s the easiest time to do it. Around Riddlesdown, the Food Standards Agency lists about 19 schools and colleges with registered kitchens within a mile and a half or so. Just call us on 0345 646 2711 or use the quote form with your term dates and we will plan around them.
Can the work in Riddlesdown be done at night or at weekends?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Riddlesdown needn’t be disturbed. Just ring 0345 646 2711 or email us with your opening times and we’ll plan around them.
Do you recommend a next date?
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.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
What is TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
How regularly does a grease trap need emptying?
That depends on the trap and the kitchen. Small under-sink units fill faster than larger traps, and busy kitchens fill them faster still. We will suggest an interval after the first clean.
Do you cover Riddlesdown?
Yes. Our area takes in London and the counties of South East England, and that includes Riddlesdown.
When to call us in Riddlesdown
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.
Most sites get in touch when they notice something like this:
- Washing-up water that will not drain away
- A kitchen drain that smells
- An interceptor full of grease and solids
- A full, neglected grease trap
If you run a care home or healthcare kitchen near Riddlesdown (the nearest hospital is Purley War Memorial Hospital, about 1 mile north-west), a grease trap on a set schedule avoids a blocked drain mid-service.

Managing agents and facilities teams in Riddlesdown
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
Why act early in Riddlesdown
Once the trap is full, grease heads for the drain. It hardens on the pipe walls until water cannot get through. Cleaning the trap regularly is far easier than clearing a blocked drain. Leaving it on a busy London site only adds to the work.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.
