Canopy cleaning in Hemel Hempstead, done properly
Grease troughs, seams and the inside edge of the canopy are the spots a daily wipe misses. Thick deposits are scraped off by hand, then the surfaces degreased to suit what’s there, using hot water or steam where it helps. The work covers grease gutters, wall canopies and baffle filters, and people most often call us about overflowing grease troughs and gutters and poor capture at the hood.
A place as big as Hemel Hempstead has kitchens of every kind, from takeaways and restaurants to school, hotel and staff kitchens. BESA’s minimum intervals run from every three months for heavy use to once a year for light use, so the right schedule depends on the kitchen.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Honest limits
An honest diagnosis matters more to us than a booking, so here’s what canopy cleaning will not do:
- A light fitting that does not work
- Poor airflow from a fan that needs repair
- A canopy too small for the cooking under it (that’s a design question)
If in doubt, call 0345 646 2711, or email photos and we’ll say what we think.

What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
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, and that’s where we come in.
The process
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes part of a shift for most kitchens, more where there are several canopies or heavy deposits. Town-centre sites in a place like Hemel Hempstead can be tight for parking, so it helps to know the options 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.
- The canopy shell, seams, troughs and gutters are degreased inside and out.
- We put the filters back, tidy up and photograph the finished canopy.
How to prepare
- Find the previous report, if there is one
- Clear the space around the work
- Allow time for equipment near the work to be turned off and cool down
Ask for a quote
Getting a quote does not take long. Send a few details and photos, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Related advice
What we are called out for in Hemel Hempstead
Most canopies have troughs or channels that catch running grease. If they’re not emptied, they fill and overflow, so fat ends up running down the front of the hood.
Look out for these warning signs:
- Smoke hanging around the canopy during service
- A hood coated in old grease
- Filters that never seem to stay clean
- Fat running down the front of the hood
If you run a church or community hall kitchen, near St Barnabas or elsewhere in Hemel Hempstead, its extract still collects grease from every lunch and event.

Keeping the system healthy
To keep the system working properly between visits:
- Clean the baffle filters often
- Check and empty canopy gutters regularly
- Never run the range with a filter out
- Report new drips or smells from the canopy
Keep the photo report with your maintenance log where an inspector can see it. Photos of a clean canopy and plenum make the record easy to follow.
Tell us if the canopy starts dripping or the filters clog sooner than usual. It can mean the cooking has changed or the interval is too long, which a grease thickness test can confirm.
Part by part
Wall canopies
Wall canopies sit against a wall over a cooking line. Grease often collects where the canopy meets the wall, so we clean along it as well as the inner skin.
Grease troughs and gutters
Where a trough drains into a grease cup, that’s emptied and cleaned too, and we will show staff where it is.
