How we handle grease filter exchange in Merstham
Think of filter exchange as routine care for the extract. It keeps airflow up and grease down between full cleans and takes a messy task off your team. The full TR19 clean then gives the system its clean bill of health. If you have a canopy running with filters missing and grease left in baffles after washing, we can help, from island canopies, wall canopies and restaurants and pubs onwards.
In a small place like Merstham, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. We agree access and timings in advance.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Between visits
No system stays clean for ever, but care slows the build-up. A few tips:
- Always run the extract while cooking
- Clean the canopy surfaces regularly
- Keep the canopy clear for exchange visits
- Watch for grease drips between visits
Your next visit is scheduled before we leave. If the kitchen gets busier, the interval can be shortened to keep up.
Clean filters plus regular full cleans keep the system in good health. A maintenance plan that covers both keeps everything on track.
Multi-site and managed buildings
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
In-house cleaning or a specialist?
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and give you a fixed quote.
What we do, step by step
Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes anything from a few minutes to an hour or so, depending on the number of filters. Pictures of the system and its access let us plan the work in Merstham before we set off.
- The filters in each canopy are measured and counted.
- An exchange schedule is agreed to suit your cooking.
- On each visit, we remove the greasy filters.
- Clean filters go in and we check they sit snugly.
- We take the greasy set away and confirm the next date.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Dig out any earlier paperwork for the system
- Arrange a key holder or contact on site
Getting a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.
Advice
How we price grease filter exchange
Some jobs are bigger than they look, and some smaller. The main factors:
- One-off work versus a regular cycle
- What state the system is in
- Access, including roofs, risers and ceiling voids
- Site rules, permits and inductions
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.

A few details help us quote accurately. With your enquiry, please include:
- Any previous report or certificate
- Wide pictures of the system and the area around it
- The roof, plant room or outside wall the system runs to

Grease filter exchange around Merstham
There are about 15 restaurants, cafés and canteens and about 4 sandwich bars and takeaways in Merstham and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. Clogged filters slow the airflow, and busy kitchens like these clog them fast. It’s Reigate and Banstead council that sends environmental health officers to food businesses in Merstham. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready. Surrey Fire and Rescue Service covers Merstham. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
A hall kitchen that only cooks for events, whether near Church of St Katharine or elsewhere in Merstham, still needs its extract cleaned, just less often. If you run a café or takeaway near Merstham station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. Term dates shape school work: for a school like Merstham Primary School, an extract clean fits neatly into a half-term or summer break.

Why act early in Merstham
Grease-loaded filters are a fire risk in their own right. Flames from the range can be drawn up into the canopy and grease in the duct can carry a fire further. Clean filters mean less fuel in the canopy. Equipment tucked in a roof space or outbuilding near Merstham rarely gets looked at unless someone books it.

Common questions in Merstham
Do you work overnight in Merstham?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Let us know the hours you are closed and we’ll book within them.
Which council inspects kitchens in Merstham?
In Merstham, it’s Reigate and Banstead council that carries out food hygiene inspections. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
What should go in our maintenance log?
Visit reports, certificates and your in-house cleaning logs. They’re what an insurer, fire officer or EHO may ask for, so keep them where they can be found quickly.
What if parts of the system cannot be reached?
We record them on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
Do you offer emergency callouts?
Yes. Our emergency line runs 24/7, for problems that can’t wait. Call us any time and explain what’s happened.
Do I get a report after the visit?
Yes, on every job. It’s a dated, written report with pictures, plus a certificate via the BESCA Vent Hygiene Elite portal for TR19® Grease cleans. File it with your fire safety records.
Where does the waste go?
It leaves the site with us when we go. While we work, it’s kept contained so the area stays clean.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
