- Grease channels that no longer drain
- Grease dripping from the canopy edge
- Condensation and grease dripping together
Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Leave the extract running until cooking stops
- Check filters aren’t leaving gaps
- Keep every filter in place while cooking
- Tell us when the canopy starts to drip
We point out anything we noticed while the canopy was apart: damaged filters, gaps around the housing or troughs that need emptying more often. We keep it to what matters.
Don’t let canopy gutters fill to the brim. Most canopy drips start with a full trough, so make emptying them part of the closing routine.
Canopy cleaning in Netherne on-the-Hill, done properly
Dripping edges and a sticky hood are the first things a visitor notices. What isn’t seen, behind the filters, tends to be worse. We clean both, so the canopy is clean where it shows and where it does not. The work covers plenum chambers, wall canopies and canopy light fittings, and the jobs we see most are canopy gutters full of old fat and heavy deposits behind the grease filters.
Kitchens in Netherne on-the-Hill, like many across London, can share a building with flats or offices, with the duct running up through shared risers. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, so a regular TR19® clean protects everyone in it.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What affects the cost of canopy cleaning
You will get a fixed price before work begins. It’s based on:
- What state the system is in
- Working hours and out-of-hours timing
- Whether it’s a one-off visit or part of a schedule
- Site rules, permits and inductions
The cost depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before we start, so there are no surprises.
Asking for a quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- The times we could work without disrupting the site
- The postcode and the type of business
- The roof, plant room or outside wall the system runs to
- Photos showing the whole system and its surroundings
Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and the last certificate or report, if there is one. Once you have those, call 0345 646 2711 or email us.
Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. 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. Reaching it takes a specialist with the right equipment.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
What else we do in Netherne on-the-Hill
When to call us in Netherne on-the-Hill
Because the plenum sits behind the filters, it’s easy to forget. Daily cleaning reaches the canopy face but rarely gets further, leaving the plenum and housing to collect grease between professional cleans.
Look out for any of the following:
- Condensation and grease dripping together
- Poor capture at the hood
- A filter housing caked in grease
- Grease dripping from the canopy edge
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Netherne on-the-Hill is St Lawrence's Hospital, about 1.9 miles east.

Common questions in Netherne on-the-Hill
Who is the fire and rescue service for Netherne on-the-Hill?
Netherne on-the-Hill is in the area of London Fire Brigade. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
What do you need to know about parking in Netherne on-the-Hill?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, typically makes it simpler.
How long is a canopy clean?
A single canopy with a light build-up is fairly quick, but large or heavily soiled canopies take longer. You will know before we start.
Who is the responsible person?
The law calls them the responsible person. That’s generally the employer or the person in control of the premises, and where several people have control, each can have duties. If you are not sure, check your lease and fire risk assessment.
Will we have to shut during the visit?
Not typically. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so the site can carry on as normal.
Are you fully insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Is canopy cleaning enough for TR19?
You can have the canopy cleaned on its own, but it won’t cover the ductwork or fan. For TR19, the whole system needs cleaning, at intervals set by BESA guidance.
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.
Why act early in Netherne on-the-Hill
Getting the canopy cleaned in Netherne on-the-Hill now saves a bigger job later. It takes a few hours for most canopies, done while the kitchen is closed. Put off, the grease simply moves further into the system. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before any work starts.

What canopy cleaning can’t fix
It’s worth knowing the limits before booking:

- Faulty canopy lights or wiring (a job for an electrician)
- Weak extraction caused by a failing fan motor
Not sure which it is? You can give us a ring on 0345 646 2711 or use the quote form and we will tell you honestly before booking.
