Grease filter exchange in Cheshunt, Hertfordshire
Grease filter exchange for Cheshunt, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Hand-washed filters that still look greasy
- Bent or damaged filters that do not sit properly
- Poor airflow through the filters
Grease filter exchange in Cheshunt
Think of filter exchange as routine care for the extract. Between full cleans, it keeps the airflow healthy and takes a messy task off your team. The full TR19 clean then gives the system its clean bill of health. The work covers island canopies, restaurants and pubs and baffle filters, and the jobs we see most are poor airflow through the filters and damaged filters letting grease past.
Many kitchens in a town like Cheshunt were fitted into buildings built for something else, which can mean awkward duct routes, long flat runs and not enough access panels. Where the duct can’t be reached, new panels can be fitted, and anything left uncleaned is recorded on the report.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

Common questions in Cheshunt
Which fire and rescue service is responsible for Cheshunt?
It’s Hertfordshire Fire and Rescue Service, which covers Cheshunt. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Which environmental health team covers Cheshunt?
Kitchens in Cheshunt are inspected by Broxbourne council’s environmental health officers. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
How often should grease filters be changed?
It varies with the type and amount of cooking. If filters clog early, the interval needs shortening and we will adjust it.
Where does the waste go?
It leaves the site with us at the end of the visit. While we work, it’s kept contained so the area stays clean.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
How much notice should we give?
Earlier is better, especially for out-of-hours work. We typically quote within one working day, and there’s a 24/7 line for emergencies.
Is there a cleaning option for the filters we have?
Yes, filters can be cleaned on a schedule as well as exchanged. We’ll talk you through which suits your kitchen when you get in touch.
What does TR19 mean?
A BESA specification, with two parts that matter most here: 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.
Kitchen extracts in Cheshunt
Food Standards Agency records list about 40 restaurants, cafés and works canteens and about 29 takeaways and sandwich shops within roughly a mile and a half of the centre of Cheshunt. Swapping filters on a schedule keeps kitchens like these drawing air properly. It’s Broxbourne council that sends environmental health officers to food businesses in Cheshunt. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready. Fire safety in Cheshunt 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.
A hall kitchen that only cooks for events, whether near St Mary the Virgin or elsewhere in Cheshunt, still needs its extract cleaned, just less often. Healthcare kitchens, like those at hospitals such as St Michaels Hospital (about 3.7 miles south-west), often cook for long hours, which puts them in BESA’s heavier-use bands.

What affects the cost of grease filter exchange
You will get a fixed price before work begins. It’s based on:
- Site requirements such as sign-in and permits
- One-off work versus a regular cycle
- Access, including roofs, risers and ceiling voids
- The condition we find in the survey
The cost depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before any work starts, so there are no surprises.
Helping us quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- Problems your staff have spotted
- Close-ups of filters, grilles, hatches or access panels
- Where the site is and what kind of site it is
- Your opening hours and when the area is out of use
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before we start.
How it works
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes less than an hour in most kitchens. A few pictures of the system and its access points help us plan a visit in Cheshunt.
- First, we record the size, type and number of filters in each canopy.
- A change schedule is agreed to match the kitchen’s cooking hours.
- At every visit, the greasy filters are lifted out.
- We fit clean filters and check they sit snugly in the housing.
- We flag any damaged filters or anything wrong with the canopy.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about parking and loading
- Let us know how we reach the system, including roofs, risers and plant rooms
Ask for a quote

Advice
What your team can do, and what needs us
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
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 can diagnose it and quote.
Do you need grease filter exchange in Cheshunt?
Wherever you are, Cheshunt included, filter washing is the job that gets skipped when the kitchen is busy. It only takes a couple of missed weeks for a filter bank to clog.
Keep an eye out for these warning signs:
- Grease building up behind the canopy filters
- Gaps where filters have been removed
- Hand-washed filters that still look greasy
- Filter washing that keeps being missed
School kitchens, at schools like Andrews Lane Primary School for example, are normally cleaned in the holidays so no lunches are lost.
Before booking anyone
- How VAT is shown on the quote
- What insurance they carry
- What happens if part of the system can’t be accessed
- Whether the figure could change on the day

Why deal with it now?
Grease dripping from the canopy is a sign the filters cannot hold any more. Drips land on surfaces and equipment below and that’s the kind of thing inspectors look for. Before an inspection or an insurer’s visit in Cheshunt, it helps to have up-to-date records.
Every site is different, 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.

Different parts, different methods
The plenum
Behind the filters sits the plenum, where air gathers before the duct. Grease that gets past the filters settles there.
Busy restaurant and pub kitchens
Kitchens that fry and grill all day load their filters fast. Their exchange schedule is typically the tightest.
