How we handle grease filter exchange in Alfold
A clean set of filters is a simple, regular dose of prevention. It keeps airflow up and grease down between full cleans, and it saves your staff a greasy job. Full TR19 cleaning still comes at the right interval, with a certificate. The work covers school and hospital kitchens, baffle filters and mesh filters, and people most often call us about gaps where filters have been removed and grease left in baffles after washing.
In a village or hamlet like Alfold, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.
Every visit ends with a written report and pictures, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Keeping the system healthy
To keep the system working properly between visits:
- Never cook with the extract switched off
- Book full TR19 cleans alongside filter changes
- Report a dripping canopy early
- Keep the canopy clear for exchange visits
Keep an eye out for filters that have been taken out. A missing filter leaves a gap for grease so tell us if you need a replacement.
Filters that are left too long stop protecting the system. A regular cycle keeps the rest of the system cleaner between full cleans.

Fixed quotes for grease filter exchange in Alfold
Before we fix a price, we need to know a few things. We look at:
- Whether it’s a one-off visit or part of a schedule
- Whether we need access equipment or extra panels
- Site requirements such as sign-in and permits
- Whether several sites go on one quote
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
Asking for a quote
You do not need the technical terms. It helps if you can send:
- The roof, plant room or outside wall the system runs to
- Where the site is and what kind of site it is
- Detail shots of panels, filters and grilles
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
For grease filter exchange in Alfold, call 0345 646 2711, or email photos. Let us know the site type and the opening hours, and send photos or your last report if you can. We normally send a fixed quote within one working day.
What staff can safely do
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, alongside our reports.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Why act early in Alfold
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. Rural sites cannot always move to another kitchen or room when something fails.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before we start.

What the work involves, part by part
Canopy filter housings
Every exchange includes a check of how the filters sit, because gaps let grease through.
Busy restaurant and pub kitchens
Heavy cooking means more grease reaching every part of the system. Regular changes help protect the ductwork.
Multi-site and managed buildings
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.
We also work for facilities teams across offices, schools and healthcare in Alfold and across Surrey. Work can be phased by floor, building or site to keep disruption down.
Common questions in Alfold
Who is the fire and rescue service for Alfold?
Alfold is in the area of Surrey Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Do you clean school canteen extracts around Alfold out of term?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Alfold. Just ring 0345 646 2711, or email photos with your term dates and we will plan around them.
Do you recommend a next date?
Yes. The recommended date is on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, and fire dampers need testing at least once a year.
How often should grease filters be changed?
It depends on how much and what the kitchen cooks. Kitchens that fry and grill all day need changes more often than lighter ones. We set a schedule that suits your kitchen.
How long does the visit take?
It depends on the size of the system, but for many sites it takes a few minutes per canopy, longer for a large kitchen with several canopies. We’ll give you a better idea when we quote.
Are you insured?
Yes. Full insurance covers our work and have been trading since 2009.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Can we skip TR19 cleans if the filters are changed regularly?
It is not. Clean filters help keep grease down, but the ducts and plenum still need cleaning at the right interval.
What happens on the day
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes anything from a few minutes to an hour or so, depending on the number of filters. Rural roads and tight entrances are worth telling us about before a visit to Alfold.
- First, we check the canopies and the filters in them.
- 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.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Tell us where we can park and unload
- Clear the space around the work
