When it’s something else
Not every problem is solved by canopy cleaning, and we’ll tell you before we start. It does not solve:
- A canopy undersized for the equipment
- Ductwork and fans beyond the canopy (those need a full TR19 clean)
- Filters that no longer seal in the housing
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we’ll tell you honestly before you book.
Parts of the system we cover

Canopy cleaning for kitchens and businesses in New Ash Green
The canopy is where the extract system breathes in. A dirty canopy passes more grease further into the system. Our diagnosis starts there, and the cure is a thorough clean of the hood, the plenum and the filter housing. The work covers baffle filters, canopy light fittings and wall canopies, and people most often call us about canopy gutters full of old fat and condensation running down the canopy.
Somewhere as small as New Ash Green, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.
Duct Doctor has been trading since 2009, as 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.

Multi-site and managed buildings
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 can quote for the whole system.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
New Ash Green: your questions answered
Can you come to New Ash Green after we close?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Just call 0345 646 2711 or email us with your opening times and we’ll plan around them.
Which environmental health team covers New Ash Green?
In New Ash Green, it’s Sevenoaks council that carries out food hygiene inspections. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Can we book visits on a schedule?
Yes, of course. Send details of the systems and how they’re used, and we’ll suggest a schedule and quote for it.
What does canopy cleaning cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we’ll normally reply within one working day.
Is New Ash Green in your area?
Yes. Our area takes in London and the counties of South East England, New Ash Green included.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and we will quote them together.
Do you have a 24/7 line?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
Can I just have the canopy cleaned instead of the whole system?
On its own, a canopy clean is a useful extra rather than a full TR19 clean. We will make clear on the report which parts were cleaned so nobody mistakes it for a full system clean.
Do you need canopy cleaning in New Ash Green?
Most canopies have troughs or channels that catch running grease. If they’re not emptied, they fill and overflow, and grease ends up dripping from the canopy edge.
Signs it’s time to call us include:
- A filter housing caked in grease
- A canopy flagged at an environmental health inspection
- A sticky, discoloured canopy
- Canopy gutters full of old fat
If you run catering at a historic house or estate in the area (Cobham College is about 4.3 miles east), event kitchens in older buildings often have awkward duct runs that need planning.
Questions to ask before booking
- When they can work, and whether that is outside your opening hours
- Whether the quote shows VAT
- Whether inaccessible sections are listed on the report
- Whether they recommend a next date
Canopy cleaning in New Ash Green: the local picture
There are about 7 restaurants, cafés and works canteens and about 3 takeaways and sandwich shops across New Ash Green and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Every kitchen among them that cooks under a canopy has a hood, plenum and filters collecting grease. It’s Sevenoaks council that sends environmental health officers to food businesses in New Ash Green. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready. New Ash Green sits within the area of Kent Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
If you run catering at a healthcare site, such as a hospital like Darent Valley Hospital about 5.2 miles north-west, the extract may need cleaning more often than a part-time kitchen. Term dates shape school work: for a school like New Ash Green Primary School, an extract clean fits neatly into a half-term or summer break.

What else we do in New Ash Green
Why deal with it now?
Grease on the canopy is sitting just above the heat source. Flames from the range can ignite it and be pulled further into the system, where a fire is much harder to stop. A clean canopy takes that fuel away. A fault that closes a site in a village like New Ash Green affects everyone who depends on it.
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and why the quote is fixed before we start.

What staff can safely do
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
What happens on the day
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes a few hours for most canopies. Somewhere like New Ash Green, lanes, gates and parking are worth mentioning in advance.
- We look at the canopy, filters and troughs first.
- Out of hours, the range is switched off, cooled and covered.
- We lift out the filters and scrape the plenum and housing.
- Inside and out, the hood and its troughs are cleaned.
- Filters are refitted, the area cleaned down and the photo report put together.
Getting ready for the visit
- Clear the space around the work
- Find the previous report, if there is one
- Plan for cooking equipment or plant to be off before we arrive

Advice
Different parts, different methods
Island canopies
The underside of an island canopy is in full view, so the finish matters. It’s degreased and photographed for your report.
Plenums and filter housings
The rails and channels that hold the filters collect grease. We clean them so the filters sit tight and leave no gaps.
