What staff can safely do
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Grease filter exchange for kitchens and businesses in Apsley
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. Our grease filter exchange service swaps dirty filters for clean ones on a schedule. The work covers restaurants and pubs, wall canopies and island canopies, and common reasons people get in touch are filters left unwashed on busy weeks and filters that leave gaps in the canopy.
For a smaller kitchen near Apsley, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. We plan the visit around your hours, with the journey sorted in advance.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Your questions about grease filter exchange in Apsley
Who carries out food hygiene inspections in Apsley?
That’s Dacorum council, whose environmental health officers carry out food hygiene inspections in Apsley. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Can the work in Apsley be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. The work in Apsley can fit around your hours. Tell us your opening hours when you ask for a quote.
Do we need to close while you work?
Normally not. Out-of-hours visits keep the disruption down. Larger jobs can be phased over several visits to keep things running.
Who has the legal duty for fire safety?
The law calls them the responsible person. It’s normally the employer, or whoever controls the building, and where several people have control, each can have duties. If you are not sure, check your lease and fire risk assessment.
What types of premises do you cover?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
Can you come out in an emergency?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
How regularly do grease filters need exchanging?
That depends on the cooking. Heavy cooking means more frequent changes than lighter ones. We set a schedule that suits your kitchen.
What should go in our maintenance log?
Every certificate and report from each visit, kept together in your maintenance log with your in-house cleaning records. BESA says certificates should show the date, location and technician.
Aftercare tips
Results last longer with the right care. We suggest:
- Do not refit a filter that’s bent
- Always run the extract while cooking
- Clean the canopy surfaces regularly
- Make sure we can reach the canopy on exchange day
Once the clean filters are in, the kitchen can cook right away. We take the greasy filters with us to be cleaned.
Saturated filters let more grease through. A regular cycle keeps the rest of the system cleaner until the next TR19 clean.
Do you need grease filter exchange in Apsley?
Kitchens in Apsley, as everywhere, find filter washing slips down the list on busy weeks. It only takes a couple of missed weeks for a filter bank to clog.
The symptoms we are asked about most are:
- Grease filters clogged with grease
- Bent or damaged filters that don’t sit properly
- Filters that come out of the sink still dirty
- A canopy running with filters missing
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (High Elms Manor is about 4.1 miles south-east), access may need planning.
What to look for in a quote
- If the quote is a fixed price or an estimate
- Whether they recommend a next date
- What’s included in the scope, part by part
- Whether the work can be done while the site is closed
What happens if it’s left?
Grease-loaded filters are a fire risk in their own right. Flames from the range can be drawn up into the canopy, and from there into the duct. Keeping filters clean takes some of that fuel away. A quieter site near Apsley still needs its system looked after.
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before any work starts.

What happens on the day
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. On site, it takes well under an hour for most canopies. Tell us about any gates, ladders or locked plant areas at your site near Apsley when you book.
- We look at the canopies and the condition of the filters.
- We note any filters that are bent, damaged or missing.
- Greasy filters are swapped for clean ones.
- The filters are checked for fit before we go.
- We tell you if the plenum or canopy needs a clean.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about parking and loading
- Mention any locked doors, roof access or ceiling voids

Kitchen extracts in Apsley
The FSA’s data shows about 23 bars, pubs and nightclubs registered within 1.5 miles or so of the middle of Apsley. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. The fire and rescue service for Apsley is 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. It’s Dacorum council that sends environmental health officers to food businesses in Apsley. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after.
Bursars and site managers at schools such as Two Waters Primary School tend to book extract cleaning for when the kitchen is empty. A kitchen near Apsley station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

What affects the quote in Apsley
We don’t publish a price list, because no two systems are the same. The quote depends on:
- Whether several sites go on one quote
- The scale of the work
- Whether we need access equipment or extra panels
- Parking and loading at the site
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.
What to send for a quote
When you contact us, it’s useful to have:
- A few general shots of the system
- The roof, plant room or outside wall the system runs to
- Your opening hours and when the area is out of use
- Detail shots of panels, filters and grilles
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.
