About our extract fan cleaning in Dorchester
Any fan serving a kitchen in Dorchester is cleaned the same careful way as anywhere else: we isolate it, open the housing, scrape the impeller and degrease the lot. The result is photographed for your records. We’re often asked to deal with a fan that has never been cleaned and hot, greasy smells near the fan, across discharge points, roof-mounted fans and fan housings.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Grease, kitchens and Dorchester
The fire and rescue service for Dorchester is Oxfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. About 47 miles out from central London, Dorchester is part of the South East area we work across. Visits are booked around your hours, evenings and weekends included.
Where a hall near Dorchester Abbey, or anywhere in Dorchester, hosts lunch clubs or events, its extract gathers grease just as a café’s does. If you look after a school kitchen, at a school such as Dorchester St Birinus Church of England School or anywhere near Dorchester, the holidays are the usual time for a TR19® clean.

What affects the cost of extract fan cleaning
The quote reflects the site in front of us. We consider:
- The condition of the system
- How easy every part is to reach
- One-off work versus a regular cycle
- Site rules, permits and inductions
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before we start.
Asking for a quote
Photos let us diagnose from a distance. Try to include:
- The roof, plant room or outside wall the system runs to
- Detail shots of panels, filters and grilles
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The site address and the type of premises
For a fixed quote, call us on 0345 646 2711 or use the quote form and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You will normally have a quote within one working day.
Why it’s worth doing now in Dorchester
Grease on a roof fan can also escape outside. It marks the area around the outlet and leaves more fuel outside, which is one more reason to keep it clean. A fault that closes a site in a village like Dorchester affects everyone who depends on it.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we’ll price it together.

Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Facilities teams in offices, schools and healthcare sites book us too in Dorchester and across Oxfordshire. Work can be phased by floor, building or site to keep disruption down.
What we do, step by step
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. The work itself takes a few hours where there are several fans or heavy deposits. If you can send photos, we can arrive in Dorchester knowing what to expect.
- 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.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Mention any parking or loading restrictions
- Name a contact who can let us in at the agreed time

Common questions in Dorchester
Can you get to a site in Dorchester?
Yes. Villages and rural sites across the South East are part of our work, Dorchester included. Photos of the system and directions to the site help us plan the visit.
Can you work in Dorchester outside opening hours?
Yes, nights and weekends are routine for us. The work in Dorchester can fit around your hours. Tell us your opening hours when you ask for a quote.
What’s the cleaning interval for an extract fan?
It’s cleaned with the whole extract at BESA’s minimum intervals for your cooking hours. Grease readings and the fan’s condition can show it needs more.
Do you need to turn the fan off to clean it?
We always isolate the fan first, so it can’t run during the clean. With the extract off, the kitchen cannot cook, so we work out of hours.
How do you keep the site clean during the work?
By covering it before any work starts. The work is kept contained and clean down when we finish.
Can you look after several sites?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
Is the fan included in a TR19 clean?
Yes, it should be. The whole system is cleaned, from the canopy to the discharge, and the fan sits right in that path, so it’s cleaned too.
Why has my extract fan got louder?
Uneven grease on the impeller often causes it. After cleaning, we’ll tell you if wear or damage is also involved.
When something else is needed
It’s worth knowing the limits before booking:
- A dirty duct upstream of the fan
- A motor that has burnt out
- Wiring faults to the fan
If you’re not sure, just ring 0345 646 2711 or send us an email and we will give you a straight answer.

Signs you need extract fan cleaning in Dorchester
How fast a fan gets greasy in Dorchester depends on the cooking: daily hours and the amount of frying and grilling. BESA guidance sets minimum intervals of 3, 6 or 12 months for the whole system by daily use.
If you notice any of these, it’s worth a diagnosis:
- A motor area thick with grease
- Fat spreading onto the roof or wall by the fan
- A noisy fan that has got louder over time
- A fan shaking on its mounts
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Clifton Hampden Manor is about 2 miles west), access may need planning.
What to look for in a quote
- What happens if part of the system can’t be accessed
- How they set the interval to the next visit
- Whether the figure could change on the day
- What paperwork you get at the end
In-house cleaning or a specialist?
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
In-house cleaning and specialist cleaning do different jobs. 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.
