About our grease filter exchange in Ash
Baffle filters and mesh filters both fill with grease. Once they’re clogged, airflow drops and the extract struggles. Regular exchange keeps the air moving. If you have bent or damaged filters that don’t sit properly and filter washing that keeps being missed, we can help.
In a smaller place like Ash, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. Quieter kitchens still collect grease in the duct, just more slowly, so cleaning is planned around how much it cooks and what the readings show.
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.

Questions from Ash
Can you work in Ash outside opening hours?
Yes, out-of-hours work is a big part of what we do. The work in Ash can fit around your hours. Tell us your opening hours when you ask for a quote.
Can school kitchens in Ash be cleaned in the holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 19 schools, colleges and universities with registered kitchens within about a mile and a half of Ash. You can phone us on 0345 646 2711 or drop us a line with the dates the site is empty.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What does grease filter exchange cost?
Filters, canopies and how often you need visits all affect the price. Tell us what you have and we’ll come back with a fixed quote, normally within one working day.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
What happens to the waste?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
Can you look after several sites?
Yes. You deal with one contact for every site in our area, and visits can be set on a regular cycle.
How much notice should we give?
The more notice, the better, particularly for night and weekend visits. We normally quote within one working day, and there’s a 24/7 line for emergencies.
Common problems we fix in Ash
Cooking vapour carries grease into the canopy. Much of it is trapped by the filters so they gradually clog until the air can barely get through.
What we are most often called out for:
- Filters left unwashed on busy weeks
- Filters so greasy the air can barely pass
- Grease collecting in the filter channels
- Missing filters in the filter bank
If you cook for passing trade around Ash station, the extract can be cleaned between your last and first customer.

What grease filter exchange looks like in Ash
Look up Ash on the FSA’s food hygiene register and you will find about 15 cafés, restaurants and staff canteens and about 18 takeaways and sandwich shops within 1.5 miles or so of the middle of Ash. Where they cook under a canopy, the grease filters are the first line of defence and clog quickly. Ash is covered by Surrey 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. In Ash, food businesses are inspected by environmental health officers from Guildford council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after photos from each clean are a simple way to show the extract is in hand.
Bursars and site managers at schools such as Walsh CofE Junior School tend to book extract cleaning for when the kitchen is empty. A hall kitchen that only cooks for events, whether near Church of St Peter or elsewhere in Ash, still needs its extract cleaned, just less often.

For rail, the closest station is Ash station, roughly 0.5 miles north-east. Other landmarks nearby include Farnham Castle (4 miles south-west) and Ash Museum (less than half a mile north-east).

What your team can do, and what needs us
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Different parts, different methods
Mesh filters
Layers of mesh catch grease droplets. They clog quickly in a busy kitchen and need frequent attention.
The plenum
The plenum is the space behind the filters. It collects whatever grease the filters miss.
Honest limits
Grease filter exchange can’t fix everything, and we’d rather say so up front. It won’t put right:
- A canopy that doesn’t capture the vapour properly
- Cooking smells reaching neighbours, which need odour control
- A noisy or failed extract fan
If you are not sure, just call 0345 646 2711 or email us and we’ll give you a straight answer.

Keeping the system healthy
So the system stays in good health:
- Always run the extract while cooking
- Make sure no filter is left out
- Clear anything stored on or near the canopy
- Watch for grease drips between visits
There’s no waiting: the canopy is ready as soon as the clean set is fitted. The dirty set leaves with us to be cleaned.
Dripping filters are a clear sign they’re full. Changing them now reduces the fuel above the cooking, and it’s worth checking the plenum too.
The process
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes a short visit, depending on how many filters the canopies hold. Around Ash, access is typically simpler than in a town centre, though gates and roof access are worth mentioning.
- We record the number, size and type of your filters.
- An exchange schedule is agreed to suit your cooking.
- On each visit, we remove the greasy filters.
- A clean set is fitted and checked for gaps.
- We take the greasy set away and confirm the next date.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Move anything stored near the system
- Have your last certificate or report to hand
Getting a quote

Managing agents and facilities teams in Ash
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
