What we do, step by step
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. In a small place like Frithsden, the journey is planned ahead and the visit arranged around the site’s hours.
- First, we record the size, type and number of filters in each canopy.
- We agree a schedule that suits how much the kitchen cooks.
- On each visit, the dirty filters come out of the canopy.
- 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.
Before we arrive
- Plan for cooking equipment or plant to be off before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Name a contact who can let us in at the agreed time

Grease filter exchange in Frithsden, done properly
We set up grease filter exchange for kitchens in Frithsden on a schedule that suits their cooking. The heavier the cooking, the more often filters need changing while a lighter kitchen can go longer. The interval is agreed before the first visit. The work covers school and hospital kitchens, wall canopies and baffle filters, and common reasons people get in touch are weak extraction at the canopy and grease building up behind the canopy filters.
For a kitchen in or near Frithsden, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How we price grease filter exchange
You’ll get a fixed price before work begins. It takes into account:
- How easy every part is to reach
- The size of the system
- Where the site is and how we reach it
- When the work can happen, such as evenings, overnight or weekends
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.
Helping us quote
We can often survey from pictures. Try to include:
- A few general shots of the system
- Close-ups of filters, grilles, hatches or access panels
- The site address and the type of premises
- The paperwork from the last visit, if you have it
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before work begins.
Grease filter exchange around Frithsden
According to Food Standards Agency records, there are about 5 bars, pubs and nightclubs within roughly a mile and a half of the centre of Frithsden. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Frithsden sits within the area of 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. Food hygiene inspections in Frithsden are the job of Dacorum council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after.
Church and community hall kitchens, near Church of St Lawrence or anywhere around Frithsden, are easy to forget, but their extracts collect grease like any other. School kitchens, at schools like Potten End CofE Primary School for example, are normally cleaned in the holidays so no lunches are lost.

Frithsden: your questions answered
Can you get to a site in Frithsden?
Yes, Frithsden is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Can the work in Frithsden be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. The work in Frithsden can fit around your hours. Let us know the hours you are closed and we’ll book within them.
How long does grease filter exchange take?
That depends on how much there is to do, but for many sites it takes anything from a few minutes to an hour or so, depending on the number of filters. We will give you a better idea when we quote.
Is TR19 a legal requirement?
Not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurers ask for proof of cleaning to it. The law behind it is the Fire Safety Order 2005, which applies in England and Wales.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Do you have insurance?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
What do you do to protect the area?
By covering it before any work starts. We keep the work contained and clean down when we finish.
In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.

Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Never leave gaps in the filter bank
- Keep canopy surfaces wiped down
- Never cook with the extract switched off
- Look out for drips from the canopy
If the plenum behind the filters looks greasy, we say so. It can be a sign that a full TR19® clean is due, and we can arrange it.
Bent or missing filters let grease straight past. Replacing them early protects the plenum and ductwork.
Different parts, different methods
School, care home and staff kitchens
For kitchens closed in the holidays, visits can be timed around term or rota, keeping the filters ready for the busy weeks.
Mesh filters
Layers of mesh catch grease droplets. In a busy kitchen, mesh soon blocks, so they need changing often.
What we are called out for in Frithsden
Washing filters by hand doesn’t always get them clean. Grease hides in the folds of a baffle or the layers of a mesh and a sink wash rarely reaches it.
Clients usually contact us after spotting something like this:
- A canopy running with filters missing
- Filters that leave gaps in the canopy
- Hand-washed filters that still look greasy
- Filters so greasy the air can barely pass
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Hemel Hempstead Hospital is the nearest hospital to Frithsden, about 3.1 miles south-east.

Leave it or put it right?
Once filters are saturated, more grease gets past them. That makes the next full clean a bigger job, and grease may build up faster than the cleaning interval allows. If the system at a site near Frithsden fails, there may be nowhere nearby to move to.
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.
