Why it’s worth doing now in Farley Green
Some kitchens in Farley Green wash filters themselves to save the cost of a service, and that can work if it’s done thoroughly and on time. Where it slips, an exchange service takes the job off staff. Equipment tucked in a roof space or outbuilding near Farley Green rarely gets looked at unless someone books it.
The cost depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.

Grease filter exchange in Farley Green
Baffle filters and mesh filters both fill with grease. Clogged filters choke the airflow and the extract struggles. A steady cycle of clean filters keeps extraction strong. If you have grease collecting in the filter channels and grease filters clogged with grease, we can help, from mesh filters, school and hospital kitchens and restaurants and pubs onwards.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
The sign-off is always in writing: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

What affects the cost of grease filter exchange
There’s no set price list, because no two systems are the same. What we look at:
- What state the system is in
- The number of sites or systems
- Any permits to work or inductions
- Travel, parking and unloading
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before we start.
Asking for a quote
A few details help us quote accurately. With your enquiry, please include:
- The roof, plant room or outside wall the system runs to
- Your opening hours and when the area is out of use
- The postcode and the type of business
- Close-ups of filters, grilles, hatches or access panels
We don’t publish a price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To start, ring 0345 646 2711 or email us.
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, and that is where we come in.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.

What we’re called out for in Farley Green
Hand-washed filters often come back still greasy. Grease lodges deep in baffles and mesh and a sink wash rarely reaches it.
Common reasons sites call us are:
- Gaps where filters have been removed
- Grease dripping from the canopy
- A greasy plenum behind the filters
- Filters left unwashed on busy weeks
Historic houses near Farley Green, such as Chilworth Manor about 2.7 miles north-west, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
What your quote should include
- What insurance they carry
- Whether inaccessible sections are listed on the report
- Whether the whole system is included, or only the parts that are easy to reach
- Whether VAT is included
What we do, step by step
On the day, we arrive 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 before we start, and the area around the work is covered and protected. On site, it takes less than an hour in most kitchens. Visits to a village like Farley Green are booked in advance, at a time that suits whoever runs the site.
- First, we record the size, type and number of filters in each canopy.
- Together we set how often the filters should be changed.
- 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.
- We flag any damaged filters or anything wrong with the canopy.
How to prepare
- Let us know about parking and loading
- Mention any locked doors, roof access or ceiling voids
- Name a contact who can let us in at the agreed time
How to get a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Advice
Grease, kitchens and Farley Green
At about 27 miles from central London, Farley Green sits well inside the area we cover. A survey and a fixed quote come first, then the visit at a time that suits you. Farley Green sits within the area of Surrey Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Healthcare kitchens, like those at hospitals such as St. Luke’s Hospital (about 4.3 miles north-west), often cook for long hours, which puts them in BESA’s heavier-use bands. A hall kitchen that only cooks for events, whether near St Michael or elsewhere in Farley Green, still needs its extract cleaned, just less often.

Managing agents and facilities teams in Farley Green
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Do not let the full clean slip because filters are changed
- Look out for drips from the canopy
- Wipe the outside of the canopy as part of daily cleaning
- Clear anything stored on or near the canopy
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.
Damaged filters leave gaps in the defence. Sorting them now keeps grease where it can be caught.
Questions from Farley Green
Can you get to a site in Farley Green?
Yes. Villages and rural sites across the South East are part of our work, Farley Green included. Photos of the system and directions to the site help us plan the visit.
Which council inspects kitchens in Farley Green?
Kitchens in Farley Green are inspected by Guildford council’s environmental health officers. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Will we have to stop cooking for a filter change?
A filter change is quick and can be timed around service. The canopy shouldn’t be used without filters so the swap is done promptly.
Can damaged filters stay in the canopy?
A badly damaged filter should be replaced. We will show you which ones on the visit.
What paperwork should we keep on file?
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.
What types of filter do you exchange?
The common types of grease filter: baffle and mesh. Tell us what you have when you ring 0345 646 2711, or send details by email and we will confirm it on site.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Where do the greasy filters go?
The greasy set leaves with us for cleaning and your staff do not have to deal with them. A clean set is fitted in their place.
