About our grease filter exchange in South Merstham
In South Merstham, our filter exchange runs on a schedule set by how much the kitchen cooks. Busy kitchens need changes more often while a lighter kitchen can go longer. The interval is agreed before the first visit. Common call-outs are for a canopy that drips grease and poor airflow through the filters, on baffle filters, wall canopies and mesh filters.
Around a smaller place like South Merstham, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. A kitchen that cooks fewer hours still builds up grease, so the interval is set by hours of use and grease readings.
A written report with pictures follows every visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How it works
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. Most of the time goes on the work itself, which takes less than an hour in most kitchens. For a place like South Merstham, we load the van from the survey notes so the work can be done in one visit where possible.
- First, we check the canopies and the filters in them.
- Any damaged or missing filters are noted.
- We exchange the dirty filters for a clean set.
- We check the filters are seated and the canopy is ready to use.
- We tell you if the plenum or canopy needs a clean.
Preparing for the visit
- Clear the space around the work
- Have your last certificate or report to hand
- Name a contact who can let us in at the agreed time

South Merstham questions
Which fire service covers South Merstham?
South Merstham is in the area of Surrey Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Can you work in South Merstham outside opening hours?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in South Merstham needn’t be disturbed. Just phone us on 0345 646 2711 or drop us a line with your opening times and we will plan around them.
What types of filter do you exchange?
We work with both baffle and mesh filters. We check what’s in your canopies first and set up the service around them.
How much does a filter exchange service 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 quickly.
How do you protect the area?
Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
Is there a survey before the work?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
What happens to the waste?
It leaves the site with us at the end of the visit. During the work, it’s contained to keep the area clean.
Does the report say when we need you again?
Yes. We put a recommended next date on the report. For kitchen extracts, BESA’s minimum intervals run from every 3 months for heavy use to every 12 months for light use, while fire dampers are tested at least annually.
In-house cleaning or a specialist?
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Keeping the system healthy
Simple habits between visits make a real difference. Our advice:
- Report a dripping canopy early
- Tell us if a filter is bent or damaged
- Clear anything stored on or near the canopy
- Let us know if your cooking hours increase
The canopy looks cleaner and the air moves better straight away. Always run the extract during cooking so they catch grease as intended.
Bent or missing filters let grease straight past. Sorting them now keeps grease where it can be caught.
Do you need grease filter exchange in South Merstham?
Sometimes a filter is taken out and never put back. Every gap in the filter bank lets grease straight into the plenum and on into the ductwork.
Signs it’s time to call us include:
- Filters that leave gaps in the canopy
- Gaps where filters have been removed
- Staff short of time to wash filters
- Smoke and heat lingering under the hood
A kitchen near Merstham station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before work begins.
