About our grease filter exchange in Boxmoor
Across Boxmoor, our filter exchange suits restaurants, pubs, cafés, schools, care homes and other kitchens, from a single canopy to several. Visits can be timed around your service so nobody has to stop cooking. If you have poor airflow through the filters and blocked baffle filters, we can put it right, from wall canopies, mesh filters and baffle filters onwards.
In a smaller place like Boxmoor, many kitchens sit in older buildings or later extensions, where the duct may cross a roof void or climb an outside wall. Flat runs collect grease and need proper access to clean.
Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Mention it if the kitchen gets busier
- Clear anything stored on or near the canopy
- Keep the extract on whenever the range is in use
- Keep every filter in place during service
Between visits, check that every filter is still in place. A missing filter leaves a gap for grease, so let us know if one goes missing or gets damaged.
Filters that are left too long stop protecting the system. Getting onto a regular exchange now keeps grease out of the plenum and ductwork until the next TR19 clean.
Grease, kitchens and Boxmoor
The FSA’s food hygiene register shows about 82 restaurants, cafés and canteens and about 52 sandwich bars and takeaways in and around Boxmoor, up to about a mile and a half out. Where they cook under a canopy, the grease filters are the first line of defence and clog quickly. The fire and rescue service for Boxmoor is Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Food hygiene inspections in Boxmoor are the job of Dacorum council’s environmental health team. 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.
Commuter trade near Hemel Hempstead station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. If you run a church or community hall kitchen, near Church of St John the Evangelist and Attached Church Hall or elsewhere in Boxmoor, its extract still collects grease from every lunch and event. School kitchens, at schools like Boxmoor Primary School for example, are usually cleaned in the holidays so no lunches are lost.

Why deal with it now?
Dripping canopies and greasy smells often start with the filters. Drips land on surfaces and equipment below and that is the kind of thing inspectors look for. You choose the date of a planned visit, and a breakdown never asks.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll explain each part.

Boxmoor: your questions answered
Do you work at weekends in Boxmoor?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Boxmoor needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Do you do school kitchen extract cleaning in Boxmoor in the summer holidays?
Yes, out-of-term visits are normal for schools. There are about 20 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Boxmoor. Booking early in the term gives the best choice of holiday dates.
What’s the right interval for changing filters?
That depends on the cooking. Kitchens that fry and grill all day need changes more often than lighter ones. We agree the interval with you.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Do you take the used filters away?
We take them away to be cleaned, so your staff do not have to wash them. A clean set is fitted in their place.
Is there a survey before the work?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Who is responsible for fire safety on the premises?
It depends on the building. Under the Fire Safety Order 2005, it’s the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
Where does the waste go?
We contain it and take it with us. We collect grease, debris and waste water as we go, so it does not spread.
How the job changes from site to site
Baffle filters
Baffle filters use overlapping metal blades that force the air to change direction. Grease is thrown out of the airstream and collects on the baffles.
School, care home and staff kitchens
Even kitchens with fixed meal times build up grease though normally at a gentler pace.
What happens on the day
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes anything from a few minutes to an hour or so, depending on the number of filters. Everything the job in Boxmoor needs is worked out beforehand, from the survey.
- We count and measure the filters in every canopy.
- We agree a schedule that suits how much the kitchen cooks.
- On each visit, the dirty filters come out of the canopy.
- We fit clean filters and check they sit snugly in the housing.
- We flag any damaged filters or anything wrong with the canopy.
Preparing for the visit
- Tell us where we can park and unload
- Tell us the best time to work, such as after service or at a weekend
- Make sure equipment near the work can be switched off and left to cool
Ask for a quote
To get a fixed quote, give us a ring on 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. We normally come back within one working day.

Staff cleaning versus specialist work
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
