What staff can safely do
Staff cleaning and specialist work are not the same thing. 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. That part needs specialist access and equipment.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Grease trap cleaning for kitchens and businesses in Cannon Hill
Think of the grease trap as a filter for the kitchen’s drains. When it’s looked after, you hardly know it’s there, but neglected, it causes blockages and smells. A regular clean keeps it healthy. If you have sinks that drain slowly and an overdue grease trap, we can put it right, from school and care home kitchens, pot wash sinks and inline grease traps onwards.
Across London, many commercial kitchens are compact and run long hours, and grease builds up behind and under equipment, on walls and ceilings, and in the drains. In Cannon Hill, deep cleans and grease trap work are normally done overnight.
Every visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Questions from Cannon Hill
Can you come to Cannon Hill after we close?
Yes, we can come after you close and finish before you open. It means the site in Cannon Hill keeps running as normal. Just ring 0345 646 2711, or email photos with your opening times and we will plan around them.
Can school kitchens in Cannon Hill be cleaned in the holidays?
Yes, holiday work suits schools best. Around Cannon Hill, the Food Standards Agency lists about 34 schools and colleges with registered kitchens within a mile and a half or so. You can give us a ring on 0345 646 2711 or email us with the dates the site is empty.
What happens if a grease trap is not cleaned?
A full trap can’t catch any more grease. The grease hardens in the pipes, leading to blocked drains and smells, and can add to fatbergs in the sewer.
Do you have insurance?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we’re fully insured.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
What should go in our maintenance log?
Everything that shows the system is looked after: reports, certificates, pictures and your own cleaning or check logs. One maintenance log per site keeps it simple.
Can you give me a price for grease trap cleaning?
Trap size, type, condition and access all affect the price. Tell us about the trap and we’ll send you a fixed quote.
What we do, step by step
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes an hour or two in most kitchens, depending on the size and condition of the trap. Most London sites can’t stop for the day, so work in Cannon Hill is typically done overnight, early in the morning or at weekends.
- We agree a time when the sinks aren’t needed.
- We open the trap and look at its condition.
- Built-up grease and food waste are taken out.
- We clean the baffles, inlet and outlet.
- We close it up, check it drains and suggest when it needs cleaning again.
Preparing for the visit
- Arrange a key holder or contact on site
- Plan for cooking equipment or plant to be off before we arrive
- Find the previous report, if there is one
Ask for a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
Advice
Different parts, different methods
Restaurant and takeaway kitchens
Busy kitchens with lots of washing-up fill traps fast. They often need the most frequent cleaning.
Inline grease traps
Inline traps often take waste from several sinks or appliances. More waste means faster filling.
Landlords, agents and facilities managers
We also work for facilities teams across offices, schools and healthcare in Cannon Hill and across Greater London. Work can be phased by floor, building or site to keep disruption down.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.

When to call us in Cannon Hill
In Cannon Hill, as everywhere, grease traps are easy to forget. Hidden under a sink or in a floor it’s often left until there’s a problem.
Most sites get in touch after spotting something like this:
- Drains clogged with fat
- Gurgling from the sink waste
- A small trap that fills too quickly
- Scheduled grease trap emptying
Healthcare kitchens, like those at hospitals such as St. Anthony's Hospital (about 1.5 miles south), cook for long hours, so deep cleans and grease trap work are planned around patients’ meals.
Before booking anyone
- Whether VAT is included
- What insurance they carry
- How they set the interval to the next visit
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
Honest limits
We won’t sell you work that doesn’t address the problem, so these are the things it won’t cover:
- Drains that are cracked or have collapsed
- Drains that need jetting rather than trap cleaning
- Blockages in the public sewer beyond the property
Not sure which it is? You can phone us on 0345 646 2711 or drop us a line and we will tell you honestly before you book.

Cannon Hill kitchens: local notes
Food Standards Agency records list about 212 restaurants, cafés and works canteens and about 52 takeaways in Cannon Hill and the streets around it, up to about 1.5 miles out. Each of them sends fat, oil and grease towards the drain, which is why grease traps need regular emptying. Most London kitchens can’t close in the day, so deep cleaning is typically done overnight. Environmental health officers from Merton council inspect food businesses in Cannon Hill. Walls, floors, ceilings and equipment are all part of what they look at. Keeping a record of deep cleans and grease trap visits helps at inspection time.
If you run a church or community hall kitchen, near St James Merton or elsewhere in Cannon Hill, a deep clean and an emptied grease trap before a busy season of events are worth booking. For busy kitchens close to South Merton station, deep cleans and grease trap work can be done after closing.
