About our grease filter exchange in St Stephens
A filter that does not sit right lets grease straight past. Bent, damaged or missing filters leave gaps and every filter is checked when we swap them. We point out any that need replacing. We’re often asked to deal with blocked baffle filters and hand-washed filters that still look greasy, across school and hospital kitchens, wall canopies and baffle filters.
Size does not change the work: a kitchen in a place like St Stephens gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

St Stephens: your questions answered
Which fire authority looks after St Stephens?
It’s Hertfordshire Fire and Rescue Service, which covers St Stephens. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Can you clean school kitchen extracts in St Stephens during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around St Stephens, the Food Standards Agency lists about 10 schools and colleges with registered kitchens within a mile and a half or so. You can give us a ring on 0345 646 2711 or drop us a line with the dates the site is empty.
What does TR19 mean?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
What paperwork should we keep on file?
Each report and certificate we give you, kept together in your maintenance log, along with your own cleaning log. BESA says certificates should show the date, location and technician.
What types of filter do you exchange?
We exchange baffle and mesh filters. At the start, we note what your canopies use so every set we bring fits.
Can you give a price for filter changes?
The cost depends on your filters and the schedule. Just give us a ring on 0345 646 2711 or send us an email for a fixed quote, typically within one working day.
Do you recommend a next date?
Yes. We put a recommended next date on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, while fire dampers are tested at least annually.
Will I get paperwork for my records?
Yes, on every job. It’s a dated, written report with photos, and TR19® Grease cleans come with a certificate through the BESCA VHE portal. Keep it in your maintenance log.

What the work involves, part by part
School, care home and staff kitchens
Kitchens that cook for set mealtimes still load their filters, though often more slowly.
Busy restaurant and pub kitchens
Heavy cooking means more grease reaching every part of the system. Changing them on time protects the ducts behind.
Managing agents and facilities teams in St Stephens
Records are where multi-site compliance often slips. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
What staff can safely do
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
How the visit works
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes a short visit, depending on how many filters the canopies hold. For a place like St Stephens, we load the van from the survey notes so the work can be done in one visit where possible.
- We start by noting how many filters you have and what type they are.
- 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
- Make sure equipment near the work can be switched off and left to cool
- Clear the space around the work
- Name a contact who can let us in at the agreed time
Get a fixed quote
Quotes are quick. Send a few details and photos, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

Grease, kitchens and St Stephens
The Food Standards Agency lists about 57 pubs and bars and about 4 hotels and B&Bs as registered food businesses within 1.5 miles or so of the middle of St Stephens. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. St Stephens is covered by 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. Kitchens in St Stephens get their food hygiene inspections from St Albans City council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready.
If you run a church or community hall kitchen, near St. Stephen's Church or elsewhere in St Stephens, its extract still collects grease from every lunch and event. School kitchens, at schools like Marlborough Science Academy for example, are usually cleaned in the holidays so no lunches are lost. Commuter trade near St Albans Abbey station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- Tell us if a filter is bent or damaged
- Look out for drips from the canopy
- Do not let the full clean slip because filters are changed
- Let us know if your cooking hours increase
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 book that in.
Filter exchange and TR19 cleaning work best together. Setting both up on a schedule means neither slips.
