About our grease filter exchange in Ridge
Baffle filters and mesh filters both fill with grease. Once they’re clogged, airflow drops and the fan has to work harder. A steady cycle of clean filters keeps extraction strong. Typical jobs include staff short of time to wash filters and a canopy running with filters missing, across island canopies, restaurants and pubs and school and hospital kitchens.
Somewhere as small as Ridge, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease, whatever the size of the place.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

For landlords and multi-site operators
We regularly work with managing agents. Send the address, what’s needed and how access works, and we will send a fixed quote.
We also work for facilities teams across offices, schools and healthcare in Ridge and across Hertfordshire. Larger estates can be phased building by building around the people who use them.
What affects the quote in Ridge
The price is fixed before any work begins. It’s based on:
- The condition we find in the survey
- Whether several sites go on one quote
- Any permits to work or inductions
- Travel, parking and unloading
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before work begins.
Asking for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- A few general shots of the system
- Where the site is and what kind of site it is
- How we’d reach plant on a roof or in a plant room
- Any access panels or hatches you can see
If you need grease filter exchange in Ridge, phone us on 0345 646 2711 or send us an email. Tell us what kind of premises it is and when it’s open, plus pictures or the previous report if they’re to hand. A fixed quote usually follows within one working day.
FAQs for Ridge
Can the work in Ridge be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. The work in Ridge can fit around your hours. When you phone us on 0345 646 2711 or drop us a line, mention when the site is quiet.
Which fire service covers Ridge?
Fire safety enforcement in Ridge is handled by Hertfordshire Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Do you recommend a next date?
Yes. The interval depends on how much the system is used and what we find and the report sets out why.
Will I get paperwork for my records?
Yes. It’s your proof that the work was done: a written, dated record with photos of what we did and anything we couldn’t access.
Can you look after several sites?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Each site gets its own report and photos.
Is there a survey before the work?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
What’s the right interval for changing filters?
The right interval depends on the kitchen. If filters are dripping or clogging before the next change, it’s too long, and we can change it.
The process
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes a short visit, depending on how many filters the canopies hold. Somewhere like Ridge, lanes, gates and parking are worth mentioning in advance.
- We record the number, size and type of your filters.
- We set the interval with you.
- On each visit, we remove the greasy filters.
- A clean set is fitted and checked for gaps.
- The dirty filters leave with us and the next visit is booked.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Move anything stored near the system
- Tell us the best time to work, such as after service or at a weekend
Getting a quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before we start.

Looking after it afterwards
After the visit, a few habits help the work last:
- Always run the extract while cooking
- Tell us if the menu or opening hours change
- Make sure no filter is left out
- Do not let the full clean slip because filters are changed
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.
Clean filters plus regular full cleans keep the system in good health. Setting both up on a schedule means neither slips.

What your team can do, and what needs us
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Kitchen extracts in Ridge
According to Food Standards Agency records, there are about 3 bars, pubs and nightclubs within about 1.5 miles of central Ridge. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Food hygiene inspections in Ridge are the job of Hertsmere 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. Fire safety in Ridge falls to 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.
If you run a church or community hall kitchen, near Church of St Margaret or elsewhere in Ridge, its extract still collects grease from every lunch and event. School kitchens, at schools like St Giles' CofE Primary School for example, are usually cleaned in the holidays so no lunches are lost. Healthcare kitchens, like those at hospitals such as Shenley Hospital (about 2.1 miles west), often cook for long hours, which puts them in BESA’s heavier-use bands.
