Common problems we fix in London Colney
The canopy takes the hottest, wettest air in the kitchen. Fat in that air settles on the inside of the hood, in its seams and on the filters, and the plenum behind them collects the rest.
Keep an eye out for these warning signs:
- Grease filters blocking between washes
- A plenum thick with grease behind the filters
- A greasy hood noticed by an inspector
- Grease channels that no longer drain
Term dates shape school work: for a school like Bowmansgreen Primary School, an extract clean fits neatly into a half-term or summer break.

Canopy cleaning in London Colney, done properly
Canopy cleaning is part of every full TR19® Grease clean, but some sites need the canopy done between full cleans. In that case, the report makes clear what was and wasn’t cleaned, so your records stay accurate. If you are dealing with grease dripping from the canopy edge and smoke hanging around the canopy during service, we can put it right.
For a smaller kitchen near London Colney, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. The visit is booked around your opening hours, and the journey is planned ahead.
The sign-off is always in writing: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Kitchen extracts in London Colney
Look up London Colney on the FSA’s food hygiene register and you will find about 17 cafés, restaurants and staff canteens and about 12 takeaways within roughly a mile and a half of the centre of London Colney. Wherever there’s a canopy over the cooking, its hood and plenum collect grease with every service. London Colney is covered by Hertfordshire 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. Environmental health officers from St Albans City council inspect food businesses in London Colney. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked.
If you run catering at a historic house or estate in the area (Batchwood Hall is about 3.9 miles north-west), event kitchens in older buildings often have awkward duct runs that need planning. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to London Colney is Napsbury Hospital, about 0.5 miles west.

When it’s something else
Some problems need a different service or another trade:
- Faulty canopy lights or wiring (a job for an electrician)
- Filters that no longer seal in the housing
- A canopy undersized for the equipment
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.

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.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.

How it works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes part of a shift for most kitchens, more where there are several canopies or heavy deposits. Everything the job in London Colney needs is worked out beforehand, from the survey.
- We look at the canopy first, from pictures or on a visit.
- Equipment below is switched off and left to cool, then sheeted.
- We remove the grease filters and clean the plenum and filter housing.
- We degrease the canopy shell, its seams and the grease troughs.
- Filters go back, the area is cleaned down and pictures are taken.
How to prepare
- Let us know about permits to work or site inductions
- Clear loose items from the work area
- Arrange a key holder or contact on site
Ask for a quote
Quotes are quick. Send a few details and photos, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Related advice
Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Flag any change in how the canopy behaves
- Give the canopy a wipe after service
- Wash or exchange the filters on a regular cycle
- Avoid harsh scourers that scratch the canopy
We recommend when the canopy, or the whole system, should next be cleaned. That date is based on your cooking hours and what we found, in line with BESA guidance.
The best thing a kitchen can do for its canopy is keep the filters clean. Wash or exchange them regularly, and never cook with one missing. Less grease gets into the plenum as a result.
What the work involves, part by part
School and staff canteen kitchens
A canteen canopy may cook fewer hours, but it still collects grease. BESA guidance still sets a minimum interval for the whole system, and the canopy is part of it.
Grease troughs and gutters
Many canopies have troughs or gutters around the edge to catch running grease. We empty and degrease them, so they can do their job again.
Why deal with it now?
A greasy canopy is fuel directly above the flame. Flames from the range can ignite it and be pulled further into the system, where a fire is much harder to stop. Cleaning it removes that fuel. Booking now means the visit to London Colney is planned around you, not forced by a breakdown.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will go through it with you.
Why book with us
- A single point of contact for sites across the South East and London
- We diagnose before we treat
- We’re fully insured
- A fixed price before any work starts
