What extract fan repair can’t fix

Before booking, it helps to know what’s not included:

  • A greasy canopy and duct that a fan repair will not touch
  • An extract system that was undersized from the start
  • Gas interlock faults that a Gas Safe registered engineer must deal with

If you’re not sure, just call 0345 646 2711 or use the quote form and we will give you a straight answer before you book.

What the work covers

  • Fan housings
  • Roof and wall fans
  • Kitchen extract fans
  • Bearings
  • Fan motors
  • Belts and pulleys

What the work involves, part by part

Roof and wall-mounted fans

An external fan faces the weather as well as the grease. Corrosion of housings and fixings is common.

Direct-drive fans

Direct-drive fans are compact and common in kitchen extracts. When the motor fails, replacing the whole fan unit can make more sense than repairing it and we’ll talk you through it.

Questions from London Colney

Is there an emergency callout for extract fans in London Colney?

Our emergency line runs 24/7, and London Colney is within the area we cover. Ring 0345 646 2711 at any hour and describe the fault. Let us know whether the fan is silent, noisy or tripping the power.

Can you come to London Colney after we close?

Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. When you phone us on 0345 646 2711, or send details by email, mention when the site is quiet.

What happens to the waste?

It’s contained and taken away. We collect grease, debris and waste water as we go, so it does not spread.

Does the report say when we need you again?

Yes. Every report includes a recommended date for the next visit, based on what we found and how the system is used.

Are you accredited?

We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.

How long does an extract fan repair take?

A typical repair takes a few hours on site, depending on the fault and the access to the fan, including testing. We will fit it around the kitchen’s hours where possible.

What paperwork should we keep on file?

Every certificate and report from each visit, filed in the maintenance log, along with your own cleaning log. BESA advises that certificates record the date, location and technician.

Who has the legal duty for fire safety?

In the words of the Fire Safety Order 2005, it’s the responsible person. It’s normally the employer, or whoever controls the building, and where several people have control, each can have duties. Your lease and fire risk assessment should make it clear.

How it works

Each visit runs to the same pattern: protect the area, isolate whatever needs isolating, do the work, clear away and leave you the report. On site, the work takes a few hours on site, depending on the fault and the access to the fan. Your opening hours decide when we come to London Colney, not ours.

  1. You describe the fault and we arrange a visit.
  2. On site, the fan is safely isolated.
  3. We diagnose the fault, checking the controls as well as the fan.
  4. A fixed quote for the repair or replacement follows.
  5. The work is done and the fan is tested running.

Preparing for the visit

  • Make sure equipment near the work can be switched off and left to cool
  • Agree a time when the area can be out of use
  • Arrange a key holder or contact on site

Ask for a quote

To get a fixed quote, ring 0345 646 2711 or email us 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’ll normally have a quote within one working day.

Advice

Staff cleaning versus specialist work

Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.

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. That is our job.

Landlords, agents and facilities managers

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.

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
