Buckinghamshire · Extract fan repair and replacement
Swan Bottom extract fan repair
Extract fan repair for Swan Bottom, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- A humming noise from the fan motor
- A fan running too slowly to clear the kitchen
- Vibration spreading from the fan into the ducts
Looking after it afterwards
Results last longer with the right care. Here’s what we suggest:
- Save our number for the 24/7 emergency line
- Avoid lowering the speed to quieten a fault
- Make sure the isolator and controls are easy to reach
- Keep a record of any trips or stoppages
Before we leave, the fan is run and checked. We explain the fault and the fix, and anything else we noticed is pointed out.
A fan that’s starting to make noise is giving you a warning. Getting it checked now means a planned repair rather than an emergency during service.
How we handle extract fan repair in Swan Bottom
Grease is hard on extract fans. Deposits on the impeller throw it out of balance and the vibration wears out bearings and fixings. That’s why we check the grease whenever we work on a fan and can arrange a TR19® clean of the whole system at the same time. The work covers belts and pulleys, roof and wall fans and kitchen extract fans, and common reasons people get in touch are a whining or grinding extract motor and poor airflow at the canopy.
In a small place like Swan Bottom, fans are often on an outside wall or roof, open to wind and rain. That, with the grease, is hard on motors and bearings.
Nothing is signed off by word of mouth: a dated report with photos of the work, 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.

How the visit works
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards.

- The fan and its controls are checked to pin down the fault.

- We fix the fault and run the fan to check it.

Advice
Why it’s worth doing now in Swan Bottom
A fan that is running slowly is not clearing the kitchen properly. Staff work in hotter, steamier air, and more grease settles where it shouldn’t. Rural sites can’t always move to another kitchen or room when something fails.
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.

What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
When a fan fails in Swan Bottom

A kitchen without a working fan has a problem to fix quickly. About 31 miles out from central London, Swan Bottom is part of the South East area we work across. A survey and a fixed quote come first, then the visit at a time that suits you.
For school kitchens, at schools like Lee Common Church of England School for example, a planned fan repair in the holidays avoids losing lunches in term time.

Swan Bottom questions
Can the work in Swan Bottom be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. That way a site in Swan Bottom doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
Who do I call if an extract fan fails in Swan Bottom?
Extract fan emergencies in Swan Bottom are covered around the clock. Use 0345 646 2711, our emergency number, at any time. Tell us where the fan is and how to reach it.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.
Does the report say when we need you again?
Yes. The report recommends when the next visit should be, based on use and what we found.
Who is the responsible person?
That depends on who controls the premises. Under the Fire Safety Order 2005, it’s the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
How far ahead should we book?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
How much time does a fan repair need?
It depends on the fault, but as a guide it takes a few hours for most repairs, longer for a full fan replacement. We will give you a better idea once we’ve diagnosed it.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before work begins, and anything we remove is contained. Before we leave, we tidy up and clean down.
For landlords and multi-site operators
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so each one has its own record.
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
How the job changes from site to site
Direct-drive fans
In a direct-drive fan, the impeller sits on the motor shaft. There are no belts, so faults tend to be in the motor, bearings or impeller.
Impellers and housings
Grease settles inside the fan housing as well as on the blades. We check both and cleaning may be part of the fix.
