About our canopy cleaning in The Folly
Every TR19® Grease clean includes the canopy, but a canopy can also need cleaning on its own, between full system cleans. Where that is the case, we will be clear that the ducts and fan aren’t included, so your records stay accurate. If you’re dealing with filters that never seem to stay clean and smoke hanging around the canopy during service, we can put it right.
Work in a small place like The Folly starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Managing agents and facilities teams in The Folly
Facilities teams in offices, schools and healthcare sites book us too in The Folly and across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
Keeping the system healthy
So the system stays in good health:
- Use non-abrasive cloths on the hood
- Clean the baffle filters often
- Leave the extract running until cooking stops
- Tell us when the canopy starts to drip
After the clean you get a photo report showing the canopy, plenum and housing before and after. It notes what was cleaned and anything we couldn’t reach, so the record is honest and complete.
A daily wipe of the hood keeps fresh grease from baking on. It won’t replace a professional clean, but it slows the build-up you can see.
What canopy cleaning looks like in The Folly
The FSA’s food hygiene register includes about 4 pubs, bars and clubs in and around The Folly, up to about a mile and a half out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. It’s St Albans City council that sends environmental health officers to food businesses in The Folly. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Hertfordshire Fire and Rescue Service covers The Folly. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
If you look after a school kitchen, at a school such as St Helen's Church of England Primary School or anywhere near The Folly, the holidays are the usual time for a TR19® clean. Historic houses near The Folly, such as Shaw's Corner about 2 miles north-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

Leave it or put it right?
A canopy clean in The Folly now stops the grease spreading further. The work takes an hour or two for one small canopy, longer where there are several, out of hours so service carries on. Put off, the grease simply moves further into the system. In a small place like The Folly, a system that fails can take a site out of use.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.

Common questions in The Folly
Which environmental health team covers The Folly?
In The Folly, it’s St Albans City council that carries out food hygiene inspections. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Will you come out to The Folly?
Yes. Villages and rural sites across the South East are part of our work, The Folly included. A survey first, from pictures or a visit, means we arrive with the right kit.
Do you have insurance?
Yes. Full insurance covers our work and have been trading since 2009.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
Who has the legal duty for fire safety?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: normally the employer or whoever controls the premises. Landlords, facilities managers and managing agents can also hold responsibility.
Are the filters cleaned too?
Filters are removed so we can clean the plenum and housing, then cleaned and refitted. Between cleans, a filter exchange service can keep them in good order.
Do you look at the system first?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. Then you get a fixed quote.
What do you do to protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
What happens on the day
Our technicians bring everything the work needs, 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. The visit takes an hour or two for one small canopy, longer where there are several. Somewhere like The Folly, lanes, gates and parking are worth mentioning in advance.
- First the canopy is surveyed, by pictures or in person.
- 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.
- Clean filters are refitted and before and after pictures go into your report.
Preparing for the visit
- Clear loose items from the work area
- Let us know about permits to work or site inductions
- Let us know about parking and loading
Ask for a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.
Related advice
Signs you need canopy cleaning in The Folly
Grease does not build up any differently in The Folly: the hours and the type of cooking decide how fast. High-heat cooking coats it fastest.
Keep an eye out for these warning signs:
- Wet, greasy drips from the hood
- Drips from the canopy onto the range
- Canopy gutters full of old fat
- An EHO comment about the canopy
Volunteers running a hall kitchen near St Helen's Church, or anywhere in The Folly, may not know when the extract was last cleaned, and a grease test settles it.
What your quote should include
- Whether the price is fixed
- Whether the work can be done while the site is closed
- What’s included in the scope, part by part
- What paperwork you get at the end
What staff can safely do
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
