Extract fan repair in Welham Green
Not every failed fan needs replacing. Often a clean, a new belt or new bearings brings it back, and that is what we’ll recommend. Where the motor has burnt out or the unit is past saving, we fit a replacement matched to the duct and the kitchen. The work covers roof and wall fans, kitchen extract fans and fan motors, and the jobs we see most are a fan shaking on its mountings and an extract fan that has stopped working.
In a place like Welham Green, extract fans are often older units on a wall or roof. An older fan that fails may be better replaced than repaired.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Keeping the system healthy
Aftercare is simple, and it helps at the next visit:
- Book regular TR19 cleaning, which includes the fan
- Get a noisy fan checked rather than slowed down
- Keep access to the fan controls unobstructed
- Keep the emergency number where staff can see it
If parts have to be ordered, we tell you how the kitchen can carry on in the meantime. We then come back and fit them at a time that suits your service.
Regular TR19 cleaning includes the extract fan. Keeping grease off the impeller is one of the simplest ways to protect it, so planned cleaning helps the fan last.
When it’s something else
Not every problem is solved by extract fan repair, and we’d rather say so up front. It does not solve:
- Faults in the building’s electrical supply, which need an electrician
- Grease throughout the ductwork, which needs a full TR19 clean
- An extract system that was undersized from the start
If in doubt, phone us on 0345 646 2711, or email photos and we will say what we think before booking.

Leave it or put it right?
It can be tempting to turn the fan down to quieten it. That reduces extraction without fixing anything while the underlying wear continues. A proper diagnosis in Welham Green gets to the real cause. When a site near Welham Green shuts unexpectedly, the people who rely on it notice at once.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, ring 0345 646 2711 or send us an email for straight advice and a fixed quote.

FAQs for Welham Green
Can you come out to a failed extract fan in Welham Green out of hours?
Extract fan emergencies in Welham Green are covered around the clock. The number to ring is 0345 646 2711. Tell us where the fan is and how to reach it.
Can you get to a site in Welham Green?
Yes. Welham Green is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
Do we need to close while you work?
Usually not. Out-of-hours visits keep the disruption down. Larger jobs can be phased over several visits to keep things running.
Will you fit a new fan if ours can’t be repaired?
We do. A replacement is matched to the system it’s going into with a fixed price agreed before any work starts.
Does the report say when we need you again?
Yes. The recommended date is on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, while fire dampers are tested at least annually.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
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 about areas you can’t get to?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
How it works
Every visit runs to the same pattern: sheeting and protection first, make the system safe, carry out the extract fan repair, tidy up and hand over the paperwork. On site, the work takes anything from an hour or two to a full visit, depending on the fault. Getting to the system matters more than parking in a place like Welham Green, so let us know how to reach it.
- We take details of the symptoms and book a time that suits the kitchen.
- We isolate the fan before touching it.
- The fan and its controls are checked to pin down the fault.
- A fixed quote for the repair or replacement follows.
- The work is done and the fan is tested running.
How to prepare
- Clear loose items from the work area
- Mention any locked doors, roof access or ceiling voids
- Make sure someone can let us in and lock up afterwards

Managing agents and facilities teams in Welham Green
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 on a regular cycle.
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
