What happens on the day
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes anything from a few minutes to an hour or so, depending on the number of filters. Somewhere as small as Holwell, the date and timings are agreed with you well before the day.
- We start by noting how many filters you have and what type they are.
- Together we set how often the filters should be changed.
- At every visit, the greasy filters are lifted out.
- Clean, dry filters are fitted in their place, with no gaps left between them.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Mention any parking or loading restrictions
- Have your last certificate or report to hand

Grease filter exchange in Holwell, done properly
Think of filter exchange as routine care for the extract. It keeps airflow up and grease down between full cleans, and it saves your staff a greasy job. Full TR19 cleaning still comes at the right interval, with a certificate. Typical jobs include grease left in baffles after washing and weak extraction at the canopy, across wall canopies, island canopies and mesh filters.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.
Nothing is signed off by word of mouth: a dated report with photos 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.

What affects the quote in Holwell
The quote reflects the site in front of us. We take into account:
- Any permits to work or inductions
- The number of sites or systems
- Travel, parking and unloading
- One-off work versus a regular cycle
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before we start.
Helping us quote
When you call or email, it’s useful to have:
- The paperwork from the last visit, if you have it
- Your opening hours and when the area is out of use
- Close-ups of filters, grilles, hatches or access panels
- Photos showing the whole system and its surroundings
If you need grease filter exchange in Holwell, give us a ring on 0345 646 2711 or send us an email. Let us know the site type and the opening hours, and send photos or your last report if you can. We typically send a fixed quote within one working day.
Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
In-house cleaning and specialist cleaning do different jobs. 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.
Managing agents and facilities teams in Holwell
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Part by part
Canopy filter housings
The filter housing holds each filter at an angle in the canopy. If it’s bent or greasy, filters won’t seat properly.
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.
What a clean won’t put right
To be straight with you, some problems need a different fix:
- Extraction problems caused by the fan rather than the filters
- Cooking smells reaching neighbours, which need odour control
- A canopy that does not capture the vapour properly
If in doubt, give us a ring on 0345 646 2711 or send us an email and we’ll say what we think before you book.

What grease filter exchange looks like in Holwell
The Food Standards Agency lists about 4 bars, pubs and nightclubs as registered food businesses across Holwell and its immediate surroundings (about a mile and a half). Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Fire safety in Holwell falls to Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. In Holwell, food businesses are inspected by environmental health officers from North Hertfordshire council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
For schools such as The Priory School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed. If you run a church or community hall kitchen, near Church of St Peter (C of E) at Corner with Holwell Road or elsewhere in Holwell, its extract still collects grease from every lunch and event. Healthcare kitchens, like those at hospitals such as Fairfield Hospital (about 2.7 miles north-east), often cook for long hours, which puts them in BESA’s heavier-use bands.

Near you in Holwell

Why deal with it now?
Once filters are saturated, more grease gets past them. The ductwork then loads up faster and grease readings can rise between cleans. Rural sites can’t always move to another kitchen or room when something fails.
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.

Common questions in Holwell
Will you come out to Holwell?
Yes. Holwell is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Who is the fire and rescue service for Holwell?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Holwell. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
Can damaged filters stay in the canopy?
We check every filter at each visit. We tell you about any that are damaged since a poor fit lets grease past.
What does grease filter exchange cost?
Pricing depends on the kitchen, so we quote once we know your filters and schedule. We give you a fixed quote before the service starts.
What’s the right interval for changing filters?
It varies from kitchen to kitchen. The schedule is based on how heavily you cook and can change if your kitchen gets busier.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’re fully insured and have been trading since 2009.
How long does grease filter exchange take?
On site, it takes anything from a few minutes to an hour or so, depending on the number of filters. Larger systems naturally take longer, and we will tell you what to expect.
