Different parts, different methods
Inline duct fans
Space around an inline fan can be tight, so we plan how to reach and clean them. Anything out of reach is recorded.
Kitchens with long cooking hours
A long-hours kitchen cannot afford a fan failure. Keeping the fan clean is part of avoiding that, and our 24/7 emergency callout is there if it happens anyway.
About our extract fan cleaning in Long Marston
We’ve been trading since 2009. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we are fully insured, with CHAS, SafeContractor and ISO 9001. The work covers in-line fans, roof-mounted fans and centrifugal fans, and common reasons people get in touch are a noisy fan that has got louder over time and a fan that has never been cleaned.
Work in a small place like Long Marston starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, 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.

Leave it or put it right?
A fan that fails mid-service can stop a kitchen cooking. Many fan problems start with grease, so keeping it clean is part of keeping it running. If it does fail, our 24/7 emergency line is there. Our emergency line runs 24/7, but a planned visit to Long Marston is calmer for everyone.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will explain each part.

What staff can safely do
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Managing agents and facilities teams in Long Marston
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.

What affects the quote in Long Marston
You’ll get a fixed price before any work starts. It’s based on:
- Whether we need access equipment or extra panels
- One-off work versus a regular cycle
- Site requirements such as sign-in and permits
- When the work can happen, such as evenings, overnight or weekends
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, give us a ring on 0345 646 2711 or use the quote form and we’ll give you an honest view and a fixed quote.
What we need to know
When you call or email, these details help:
- The paperwork from the last visit, if you have it
- Close-ups of filters, grilles, hatches or access panels
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, and then give you a fixed quote. To get going, give us a ring on 0345 646 2711, or send details by email.
Long Marston: your questions answered
Which fire and rescue service is responsible for Long Marston?
Long Marston is in the area of Hertfordshire Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Is Long Marston within the area you cover?
Yes. Long Marston is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Are you insured?
Yes. Full insurance covers our work and have been trading since 2009.
What happens if you cannot reach some of it?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
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.
How often does the fan need cleaning?
It’s cleaned with the whole extract at BESA’s minimum intervals for your cooking hours. Readings may show it needs cleaning more often.
Is the fan included in a TR19 clean?
Yes, the fan is cleaned as part of TR19. Anything that can’t be reached is recorded, so you always know what was cleaned.
Who has the legal duty for fire safety?
It depends on the building. The Fire Safety Order 2005 puts the duty on the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
What happens on the day
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes a couple of hours per fan, depending on its size and the build-up. We agree a date with you, plan the drive to Long Marston and turn up when the site is quiet.
- 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.
- The fan goes back into service with a report on its condition.
Preparing for the visit
- Agree a time when the area can be out of use
- Move anything stored near the system
- Mention any locked doors, roof access or ceiling voids

Extract fan cleaning in Long Marston: the local picture
The FSA’s food hygiene register includes about 3 pubs, bars and clubs across Long Marston and its immediate surroundings (about a mile and a half). Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Hertfordshire Fire and Rescue Service covers Long Marston. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. It’s Dacorum council that sends environmental health officers to food businesses in Long Marston. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after photos from each clean are a simple way to show the extract is in hand.
A hospital like Tindal Centre, about 4.4 miles west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Do you need extract fan cleaning in Long Marston?
Poor filters mean a greasier fan. When filters don’t seal, grease goes straight through to the fan, so the fan takes far more than it should.
Signs it’s time to call us include:
- Vibration from an unbalanced impeller
- Grease stains around the discharge
- Grease around the motor and its mounts
- Rough running from the extract fan
Bursars and site managers at schools such as Long Marston VA Church of England Primary School tend to book extract cleaning for when the kitchen is empty.
