About our extract fan cleaning in South Merstham
We have been trading since 2009. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, with CHAS, SafeContractor and ISO 9001 and full insurance. If you are dealing with burning smells from the fan area and fat spreading onto the roof or wall by the fan, we can help, from fan housings, discharge points and axial fans onwards.
For a smaller kitchen near South Merstham, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. We plan the visit around your hours, with the journey sorted in advance.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

South Merstham questions
Which environmental health team covers South Merstham?
Kitchens in South Merstham are inspected by Reigate and Banstead council’s environmental health officers. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Can you get to a site in South Merstham?
Yes, South Merstham is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
What should I send you?
Some photos and a quick description of the system plus the address and your hours. We’ll ask for anything else we need.
Will we have to shut during the visit?
Not normally. The area we’re working in has to be out of use while we are there, so we book a time when it would be closed anyway.
Does the law say we must follow TR19?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and without records, many insurers may refuse or reduce a claim.
Do you have a 24/7 line?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
What types of premises do you cover?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Do you repair extract fans as well as clean them?
A fan that needs repair is noted on the report, with what we found. We offer extract fan repair and replacement, and if it fails outright, our 24/7 emergency line is there.
Fixed quotes for extract fan cleaning in South Merstham

What we need to know
When you contact us, these details help:
- A few general shots of the system
- The times we could work without disrupting the site
- Any symptoms, from odd noises to smells or leaks
- Where the site is and what kind of site it is
If you need extract fan cleaning in South Merstham, call us on 0345 646 2711, or email photos. Let us know the site type and the opening hours, plus photos or the previous report if they’re to hand. We normally send a fixed quote within one working day.
The process
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes an hour or two for most single fans. A site near South Merstham normally has room to park, so the questions are about access to the system and your hours.
- We locate the fan and plan how to reach and isolate it.
- It’s isolated so it can’t run while we work.
- Grease is scraped off the impeller blades and casing.
- Blades, housing and surrounds are degreased with care around the electrics.
- It’s closed up, run, checked and photographed for the report.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know about permits to work or site inductions
- Plan for cooking equipment or plant to be off before we arrive
Get a fixed quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Advice
What staff can safely do
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
What a clean won’t put right
We’ll always give you a straight diagnosis, so here’s what this work can’t put right:
- A motor that has burnt out
- Electrical faults in the fan’s supply or controls (an electrician’s job)
- A cracked or broken impeller (it needs replacing)
If you’re not sure, just give us a ring on 0345 646 2711 or email us and we will give you a straight answer before booking.
Parts of the system we cover
- In-line fans
- Axial fans
- Centrifugal fans
- Roof-mounted fans
- Fan housings
- Discharge points
Multi-site and managed buildings
Facilities teams in offices, schools and healthcare sites book us too across Surrey. Work can be phased by floor, building or site around the people who use them.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.

Different parts, different methods
Inline duct fans
Inline fans can be in tight spaces, so we plan how to reach and clean them. Anything out of reach is recorded.
Kitchens with long cooking hours
In a busy kitchen, the fan rarely gets a rest, so grease and wear build up together. Cleaning on time helps keep it running.
