How we handle canopy cleaning in Whippendell Bottom
Has the canopy started to drip or look neglected? A photo of the canopy and filters is a good start when you call 0345 646 2711, or send details by email, and we’ll send you a fixed quote for canopy cleaning, normally within one working day. We’re often asked to deal with filters that clog soon after cleaning and a hood coated in old grease, on canopy light fittings, wall canopies and plenum chambers.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What happens on the day
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. We agree a date with you, plan the drive to Whippendell Bottom and turn up when the site is quiet.
- We look at the canopy, filters and troughs first.
- Once the kitchen has closed, the cooking line is cooled and sheeted.
- With the filters removed, the plenum and filter channels are cleaned.
- Inside and out, the hood and its troughs are cleaned.
- Filters are refitted, the area cleaned down and the photo report put together.

Signs you need canopy cleaning in Whippendell Bottom
Moisture in the air mixes with the grease on the canopy. Water vapour condenses on the cooler canopy surfaces and drips and runs with the grease. The result is sticky streaks and drips onto the range.
Keep an eye out for these warning signs:
- A canopy flagged at an environmental health inspection
- Drips from the canopy onto the range
- A canopy that no longer draws the smoke away
- Grease channels that no longer drain
Where a hall near Church of St Paul, or anywhere in Whippendell Bottom, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

What happens if it’s left?
Getting the canopy cleaned in Whippendell Bottom now saves a bigger job later. It takes an hour or two for one small canopy, longer where there are several, done while the kitchen is closed. Left alone, grease keeps moving into the plenum and duct. Planning a trip to Whippendell Bottom ahead is easier for everyone than a rushed one.

Grease, kitchens and Whippendell Bottom
The Food Standards Agency lists about 11 pubs and bars as registered food businesses within roughly a mile and a half of the centre of Whippendell Bottom. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Whippendell Bottom is covered by Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Food hygiene inspections in Whippendell Bottom are the job of Dacorum council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after.
If you run catering at a historic house or estate in the area (Chenies Manor House is about 3.4 miles south-west), event kitchens in older buildings often have awkward duct runs that need planning. Bursars and site managers at schools such as Kings Langley School tend to book extract cleaning for when the kitchen is empty.

What the work involves, part by part
Plenums and filter housings
Filter housings hold the filters in place, and their channels fill with grease. Clean housings let the filters seat properly and leave no gaps.
School and staff canteen kitchens
Canteen staff see the canopy, not the duct behind it. We clean it and the plenum behind the filters, so what’s out of sight is dealt with too.

In-house cleaning or a specialist?
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Common questions in Whippendell Bottom
Can a school canteen extract in Whippendell Bottom be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 5 schools and colleges with food registrations within roughly a mile and a half of Whippendell Bottom. Tell us your holiday dates and we will book the visit for when the site is empty.
Can the work in Whippendell Bottom be done at night or at weekends?
Yes, we can come after you close and finish before you open. It means the site in Whippendell Bottom keeps running as normal. When you ring 0345 646 2711 or send us an email, mention when the site is quiet.
Which kinds of sites do you work on?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
What kinds of canopies do you clean?
Wall canopies, island canopies and single hoods over individual appliances. The method is the same: filters out, plenum and housing cleaned, canopy degreased inside and out.
Do you offer emergency callouts?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
How much of the canopy do you clean?
All of it: the outer surfaces, the inner skin, the seams and the troughs. We also remove the filters and clean the plenum and housing behind them because that’s often the dirtiest part.
Are the filters cleaned too?
We take them out, clean them and put them back. Between cleans, a filter exchange service can keep them in good order.
How far ahead should we book?
The more notice, the better, particularly for night and weekend visits. We usually quote within one working day, and emergencies are covered by our 24/7 line.
