How we price grease filter exchange
The survey tells us what the work involves. The main factors are:
- One-off work versus a regular cycle
- Site rules, permits and inductions
- The condition of the system
- Whether several sites go on one quote
You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711 or drop us a line, and we’ll explain what it covers.
Helping us quote
To speed up the quote, send us:
- Your opening hours and when the area is out of use
- Where the site is and what kind of site it is
- Your last certificate, test record or report
- Wide pictures of the system and the area around it
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before we start.
About our grease filter exchange in Whempstead
The filters in the canopy are the first thing cooking vapour meets. Their job is to stop grease getting further into the system and they do it best when they’re clean. With grease filter exchange, clean filters replace greasy ones at regular intervals. The work covers baffle filters, restaurants and pubs and wall canopies, and people most often call us about staff short of time to wash filters and a greasy plenum behind the filters.
Somewhere as small as Whempstead, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Whempstead questions
Which fire authority looks after Whempstead?
Fire safety enforcement in Whempstead is handled by Hertfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Do you work at weekends in Whempstead?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Just call 0345 646 2711, or send details by email with your opening times and we will plan around them.
What paperwork should we keep on file?
Each report and certificate we give you, filed in the maintenance log, along with your own cleaning log. BESA says certificates should show the date, location and technician.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Which accreditations do you hold?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We are fully insured and have been trading since 2009.
Is there a cleaning option for the filters we have?
Yes, filters can be cleaned on a schedule as well as exchanged. We will explain the options when we quote.
Will we have to shut during the visit?
Not usually. The area we are working in has to be out of use while we are there, so the visit goes in a quiet slot.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.
What we do, step by step
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes well under an hour for most canopies. A quick note on how to find the site and where to park makes a visit to Whempstead run smoothly.
- We look at the canopies and the condition of the filters.
- Any damaged or missing filters are noted.
- Greasy filters are swapped for clean ones.
- The filters are checked for fit before we go.
- Anything that needs attention, such as a greasy plenum, is pointed out.

Grease, kitchens and Whempstead
Food Standards Agency records include about 4 bars, pubs and nightclubs in and around Whempstead, up to about a mile and a half out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Fire safety in Whempstead falls to Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Environmental health officers from East Hertfordshire council inspect food businesses in Whempstead. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.
Volunteers running a hall kitchen near Parish Church of All Saints, or anywhere in Whempstead, may not know when the extract was last cleaned, and a grease test settles it. If you look after a school kitchen, at a school such as Munden Church of England Voluntary Controlled Primary School or anywhere near Whempstead, the holidays are the usual time for a TR19® clean.

Why act early in Whempstead
Some kitchens in Whempstead wash filters themselves to save the cost of a service, and that can work if it’s done thoroughly and on time. Where it slips, an exchange service takes the job off staff. In a small place like Whempstead, a system that fails can take a site out of use.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.

What we’re called out for in Whempstead
However long the kitchen cooks each day, the filters see every minute of it. Heavy daily use means fast build-up so changes need to come round sooner.
Any of these means the system needs a check-up:
- Filters so greasy the air can barely pass
- Grease dripping from the canopy
- Damaged filters letting grease past
- Hand-washed filters that still look greasy
Historic houses near Whempstead, such as Aston Bury about 2.6 miles west, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
What to look for in a quote
- Whether they recommend a next date
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- If they look at the system before pricing
- Whether a written report and pictures are included
In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Between visits
So the system stays in good health:
- Look out for drips from the canopy
- Make sure we can reach the canopy on exchange day
- Keep every filter in place during service
- Wipe the outside of the canopy as part of daily cleaning
If the plenum behind the filters looks greasy, we say so. That might mean bringing a TR19® clean forward and we can book that in.
If filters are already dripping, they’re overdue. A clean set right away cuts the grease in the canopy and the plenum may need a clean as well.
