About our canopy cleaning in Underriver
Duct Doctor has cleaned canopies and hoods since 2009. As a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, we treat the canopy as one part of a whole system, and we’re fully insured, with CHAS, SafeContractor and ISO 9001. The work covers plenum chambers, baffle filters and grease gutters, and people most often call us about a plenum thick with grease behind the filters and poor capture at the hood.
In a small place like Underriver, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- A canopy too small for the cooking under it (that’s a design question)
- Electrical faults in the canopy
- Filters that no longer seal in the housing
If in doubt, ring 0345 646 2711, or email photos and we will say what we think.

Do you need canopy cleaning in Underriver?
Any canopy in Underriver that’s used for cooking will gather grease in the end. It’s fuel, sitting directly over the burners, which is why a flare-up near a dirty canopy is so dangerous.
Signs it’s time to call us include:
- Poor capture at the hood
- A sticky, discoloured canopy
- A filter housing caked in grease
- Canopy gutters full of old fat
If you run catering at a healthcare site, such as a hospital like Sevenoaks Hospital about 3.2 miles north-west, the extract may need cleaning more often than a part-time kitchen.

Your questions about canopy cleaning in Underriver
Do you work overnight in Underriver?
Yes, out-of-hours work is a big part of what we do. The work in Underriver can fit around your hours. Let us know the hours you are closed and we’ll book within them.
Which fire and rescue service is responsible for Underriver?
It’s Kent Fire and Rescue Service, which covers Underriver. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Can you come out in an emergency?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
How far ahead should we book?
The more notice, the better, particularly for night and weekend visits. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.
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. Your report lists exactly what was cleaned so nobody mistakes it for a full system clean.
What happens to the waste?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Do you work in Underriver?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Underriver.
Does the law say we must follow TR19?
No. TR19® itself isn’t law; it’s a BESA specification. 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.

How we price canopy cleaning

- The scale of the work
- Site rules, permits and inductions

A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before we start.

- The times we could work without disrupting the site

Between visits
Once we’ve finished, these simple steps help:
- Don’t scrape the canopy with metal tools
- Empty the grease troughs before they fill
- Wash or exchange the filters on a regular cycle
- Wipe the canopy down at close every day
A full system clean comes with a TR19 certificate from the BESCA Vent Hygiene Elite portal. Where only the canopy is done, the report says so clearly.
Clean filters are the canopy’s first defence. Wash or exchange them regularly, and make sure they’re all in place before cooking. The plenum behind them stays cleaner.
What the work involves, part by part
Plenums and filter housings
The rails and channels that hold the filters collect grease. Clean housings let the filters seat properly and leave no gaps.
Pub and hotel kitchens
In pubs and hotels, the kitchen may be busy for much of the day. Long hours mean the canopy collects grease fast, and canopy cleans between full cleans can help.
Kitchen extracts in Underriver
Food Standards Agency records list about 6 restaurants, cafés and works canteens in and around Underriver, up to about a mile and a half out. Each canopy in those kitchens catches grease on the inside of the hood and behind the filters. Underriver sits within the area of Kent Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. It’s Sevenoaks council that sends environmental health officers to food businesses in Underriver. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after.
Term dates shape school work: for a school like Sevenoaks Preparatory School, an extract clean fits neatly into a half-term or summer break. Knole House, about 1.6 miles north-west, is one of the historic houses near Underriver; if you run event catering at a venue like that, cleans can be booked between functions.

How the visit works
Everything the job needs comes with us, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. On site, the work takes a few hours for most canopies. In a small place like Underriver, the journey is planned ahead and the visit arranged around the site’s hours.
- 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.
- We put the filters back, tidy up and photograph the finished canopy.
Getting ready for the visit
- Have your last certificate or report to hand
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Name a contact who can let us in at the agreed time
Getting a quote
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 many jobs can be priced from that alone.
