How we handle extract fan cleaning in Merstham
Think of the fan as the system’s heart and the grease as a clot. A heart under strain works harder for less. Our job is to clear it, check it runs smoothly and record what we found so you get a clean bill of health. The work covers discharge points, centrifugal fans and axial fans, and the jobs we see most are a fan left out of previous cleans and a fan coated in grease inside its housing.
In a village or hamlet like Merstham, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.
Each visit ends with a written report and photos, 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.

What staff can safely do
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We will take a look and send you a fixed 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. Cleaning inside ducts and units is specialist work.
Managing agents and facilities teams in Merstham
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Tell us if the extract feels weaker
- Don’t turn the fan off mid-service
- Report rattles or humming early
- Watch for grease marks around the outlet
When the fan is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. If only the fan is cleaned, the photo report says so.
The fan stays cleaner when less grease gets past the canopy. Clean, well-seated filters are the fan’s first protection, and replace any that are damaged.
Different parts, different methods
Kitchens with long cooking hours
When a busy kitchen’s fan fails, cooking stops. A clean fan is less likely to strain, and our 24/7 emergency callout is there if it happens anyway.
Inline duct fans
An inline fan can be easy to forget because it’s out of sight. The survey makes sure it’s part of the clean.
Merstham: your questions answered
Can you come to Merstham after we close?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. When you call 0345 646 2711 or send us an email, mention when the site is quiet.
Can school kitchens in Merstham be cleaned in the holidays?
Yes, and it’s the easiest time to do it. With about 4 schools and colleges on the FSA’s register within roughly a mile and a half of Merstham, it pays to plan holiday dates ahead. You can ring 0345 646 2711 or use the quote form with the dates the site is empty.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we will talk you through the next steps.
Do we lose a day’s trading?
Usually not. Out-of-hours visits keep the disruption down. Larger jobs can be phased over several visits to keep things running.
Do you work in Merstham?
Yes. Our area takes in London and the counties of South East England, and that includes Merstham.
How long does extract fan cleaning take?
A single accessible fan doesn’t take long, but hard-to-reach fans take more time. It’s done while the kitchen is closed.
Are you insured?
Yes. We are fully insured, and the details are available on request.
What does TR19 mean?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
The process
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. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. The work itself takes an hour or two for one fan, longer when it’s hard to reach. Seeing the system in photos first means the trip to Merstham can be planned properly.
- Diagnosis first: we look for grease, noise and vibration.
- With the fan isolated, the housing is opened.
- The impeller is cleaned blade by blade so it runs balanced.
- We clean the casing, the outlet and around the motor.
- We run the fan and note its condition in the photo report.
Before we arrive
- Let us know about permits to work or site inductions
- Tell us where we can park and unload
- Dig out any earlier paperwork for the system
Getting a quote
For a fixed quote, give us a ring on 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. We usually come back within one working day.

How we price extract fan cleaning
We quote each job individually. This is what makes a difference:
- The number of sites or systems
- How easy every part is to reach
- Travel, parking and unloading
- Site requirements such as sign-in and permits
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
What we need to know
A few details help us quote accurately. When you get in touch, it helps to send:
- Your last certificate, test record or report
- Any access panels or hatches you can see
- The site address and the type of premises
- Problems your staff have spotted
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Why deal with it now?
For a kitchen in Merstham, a noisy, greasy fan is often the first sign the whole system is overdue. Grease on the fan means grease in the duct before it so a full TR19 clean may be due. It’s simpler to plan the work at Merstham now than to arrange it in a hurry later.
You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711 or use the quote form, and we’ll explain what it covers.

Kitchen extracts in Merstham

Grease builds up on fan blades and housings in kitchens like these, unbalancing the impeller. It’s Reigate and Banstead council that sends environmental health officers to food businesses in Merstham. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Merstham 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.
If you run a church or community hall kitchen, near Church of St Katharine or elsewhere in Merstham, its extract still collects grease from every lunch and event. 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. If you run catering at a healthcare site, such as a hospital like St Lawrence's Hospital about 2.3 miles north-east, the extract may need cleaning more often than a part-time kitchen.
