How we price extract fan repair
The diagnosis comes before the price. The main factors are:
- Whether several sites go on one quote
- What state the system is in
- How easy every part is to reach
- Site rules, permits and inductions
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before any work starts.
What to send for a quote
To speed up the quote, send us:
- How we’d reach plant on a roof or in a plant room
- Where the site is and what kind of site it is
- Your opening hours and when the area is out of use
- Photos showing the whole system and its surroundings
For a fixed quote, give us a ring on 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. You will typically have a quote within one working day.
How we handle extract fan repair in Preston
Every fan job begins with finding the fault. Noise can come from grease on the impeller, worn bearings or a slipping belt, while a fan that will not start may have a motor or control fault. We explain the problem, and what it will take, before we start. If you have an old fan that needs replacing and a fan shaking on its mountings, we can help.
Rural kitchens often have fans mounted on outside walls or roofs, exposed to the weather. Weather and grease together wear out motors and bearings.
A written report with photos follows every visit, 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.

Part by part
Direct-drive fans
An impeller coated in grease vibrates straight into the motor bearings. Sometimes a clean is all it needs, if the bearings haven’t been damaged.
Impellers and housings
Where an impeller is bent or corroded, cleaning won’t help. It may be replaced on its own, or with the whole fan.
What extract fan repair can’t fix
We will always give you a straight diagnosis, so here’s what extract fan repair will not do:
- Gas interlock faults that a Gas Safe registered engineer must deal with
- Wiring and supply faults beyond the fan itself
- Grease throughout the ductwork, which needs a full TR19 clean
If in doubt, ring 0345 646 2711, or send details by email and we’ll say what we think before booking.
Where we work
- Belts and pulleys
- Bearings
- Kitchen extract fans
- Fan motors
- Roof and wall fans
- Fan housings
Leave it or put it right?
Where the cooking gas supply is interlocked with the extract, a failed fan can stop the kitchen cooking. Without extraction, the heat and fumes build up fast and fixing the fan early avoids a forced shutdown. Out of sight is the usual reason a rural system goes too long without attention.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before work begins.

Extract fan repair around Preston
About 29 miles out from central London, Preston is part of the South East area we work across. Evening, overnight and weekend visits are all possible. Kitchens in Preston get their food hygiene inspections from North Hertfordshire council. Under food hygiene rules, a kitchen needs suitable and sufficient ventilation. That makes a fan repair urgent rather than something to put off.
For school kitchens, at schools like Preston Primary School for example, a planned fan repair in the holidays avoids losing lunches in term time. Occasional-use kitchens, such as a hall kitchen near Church of St Martin or elsewhere in Preston, are where a stiff or seized fan can turn up.
Preston is about 3 miles south of Hitchin, in Hertfordshire. Whatever kind of site you run in Preston, we can take on extract fan repair.

The process
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. Most of the time goes on the work itself, and that takes a few hours for most repairs, longer for a full fan replacement. Pictures of the system and its access let us plan the work in Preston before we set off.
- We agree a time to attend, out of hours if needed.
- The extract is switched off and the fan opened up.
- We inspect every moving part and the fixings.
- You hear whether repair or replacement makes sense, with a fixed quote.
- The fan is repaired or replaced, then checked running.
Getting ready for the visit
- Mention any parking or loading restrictions
- Allow time for equipment near the work to be turned off and cool down
- Clear loose items from the work area

Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
We also work for facilities teams across offices, schools and healthcare across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.
What staff can safely do
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.

Common questions in Preston
Can you work in Preston outside opening hours?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Preston needn’t be disturbed. Let us know the hours you’re closed and we’ll book within them.
What if my kitchen extract fan stops in Preston at night?
We run a 24/7 emergency line for failed extract fans, and Preston is part of our area. Phone 0345 646 2711 and we’ll talk through the fault and access. Details of the make and model help us plan the repair.
What should go in our maintenance log?
The reports and certificates from each visit, plus your own logs. They’re what an insurer, fire officer or EHO may ask for, so keep them together and easy to find.
Who is responsible for fire safety on the premises?
The law calls them the responsible person. It’s normally the employer, or whoever controls the building, and in shared buildings more than one person can have duties. Your lease and fire risk assessment should make it clear.
What about areas you can’t get to?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
Are you insured?
Yes. We carry full insurance, and we’ve been trading since 2009.
Should the fan be cleaned as well as repaired?
The ductwork is a separate job. We will point out grease where we find it and quote for a TR19 clean if it’s needed.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
