Extract fan repair near Harrow

What happens on the day

Every visit runs to the same pattern: protect the area, make the system safe, do the work, tidy up and hand over the paperwork. The visit itself takes a few hours for most repairs, longer for a full fan replacement. Getting kit into a London building takes planning, so let us know where we can load and park in Harrow.

  1. We start with the symptoms, such as rattling, humming, slow running or a fan that will not start.
  2. Power to the fan is isolated before we open the housing.
  3. The impeller, bearings, belts or drive, motor and mounts are all inspected.
  4. We explain the fault and give you a fixed price for the fix.
  5. Once the work is done, we run the fan and check it’s steady and quiet.

Getting ready for the visit

  • Have your last certificate or report to hand
  • Tell us where we can park and unload
  • Tell us about site rules, permits or sign-in

Getting a quote

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

Extract fan repair for kitchens and businesses in Harrow

A faulty fan does not always mean a new one. Often a clean, a new belt or new bearings brings it back and we will say so. Where the motor has burnt out or the unit is past saving, a replacement suited to the system goes in. If you have a fan shaking on its mountings and a whining or grinding extract motor, we can put it right, from kitchen extract fans, roof and wall fans and fan motors onwards.

London extract fans often sit on rooftops, exposed to the weather as well as the grease, and bearings, belts and motors wear out in the end. A fan that is noisy or vibrating is giving a warning.

The sign-off is always in writing: 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. Any parts we couldn’t reach are recorded on it too.

Do you need extract fan repair in Harrow?

In Harrow, as anywhere, long cooking days mean long hours for the fan. Belts on a belt-driven fan stretch and wear and a slipping belt means slower fan speed and weaker extraction.

Clients typically contact us when they notice one of these:

  • An old fan that needs replacing
  • A belt-driven fan that squeals
  • A knocking noise from the extract fan
  • A fan that keeps cutting out

If you run a kitchen close to Harrow-on-the-Hill station and the extract fan is getting noisy, a planned repair after closing beats a breakdown at the rush.

What your quote should include

  • Whether inaccessible sections are listed on the report
  • How they set the interval to the next visit
  • Whether VAT is included
  • When they can work, and whether that is outside your opening hours

Questions to ask before you book

Keeping the system healthy

Results last longer with the right care. Here’s what we suggest:

  • Keep the fan on a planned cleaning cycle
  • Tell us about a new rattle or whine right away
  • Don’t turn the fan down to hide a noise
  • Keep the emergency number where staff can see it

Grease on the fan usually means grease in the duct as well. A full TR19® clean deals with the canopy, ductwork and fan together, with a certificate and photo report.

Noise is normally the first sign of a fan problem. Getting it checked now means a planned repair instead of a breakdown at the worst moment.

How we price extract fan repair

The price is fixed before any work begins. It’s based on:

  • Site requirements such as sign-in and permits
  • A single visit or a regular plan
  • The condition we find in the survey
  • How many systems or sites are involved

Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.

What we need to know

Photos and a few facts are often enough to price the work. Send what you can of the following:

  • Wide pictures of the system and the area around it
  • Any access panels or hatches you can see
  • The paperwork from the last visit, if you have it
  • When the site is open and when it’s quiet

To get a fixed quote, call us on 0345 646 2711 or use the quote form with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.

When something else is needed

We will not sell you work that doesn’t address the problem, so these are the things it will not cover:

  • Problems with the electrical supply to the fan (an electrician’s job)
  • Problems with the gas supply or its interlock valve
  • Ductwork designed too small for the kitchen’s cooking

If in doubt, phone us on 0345 646 2711, or send details by email and we’ll say what we think before you book.

Extract fan repair around Harrow

Look up Harrow on the FSA’s food hygiene register and you will find about 280 restaurants, cafés and works canteens and about 127 sandwich bars and takeaways within roughly a mile and a half of the centre of Harrow. A kitchen with a dead extract fan gets hot and smoky fast, and kitchens like these feel it at once. It’s Harrow council that sends environmental health officers to food businesses in Harrow. A kitchen with no working extract can fall short of the suitable and sufficient ventilation food hygiene rules expect. That makes a fan repair urgent rather than something to put off. Lifting a replacement fan onto a London roof can need a loading slot and the building’s agreement.

If you run a school kitchen, at a school such as Whitmore High School or nearby, a fan that is getting noisy is best repaired in the holidays before it fails in term. Occasional-use kitchens, such as a hall kitchen near Church of St Peter or elsewhere in Harrow, are where a stiff or seized fan can turn up.

FAQs for Harrow

Who would carry out a food hygiene inspection at a kitchen in Harrow?

In Harrow, it’s Harrow council that carries out food hygiene inspections. Inspections are risk-based, so a visit can come at any time, including the week a fan stops.

Do you work overnight in Harrow?

Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.

Does a fan repair include cleaning the ductwork?

A fan repair on its own does not include the ductwork. We will point out grease where we find it and quote for a TR19 clean if it’s needed.

Does a faulty extract fan always need replacing?

Repair is always our starting point. Where the motor has burnt out or the fan is worn out, replacing it can be the better answer, and we’ll explain why.

Do you offer emergency callouts?

Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.

Do you work with multi-site operators?

Yes. Tell us the addresses and what each needs and we’ll quote them together.

What causes a noisy extract fan?

Common causes are grease on the impeller, worn bearings, slipping belts and loose mountings. Each sounds a little different and we find the exact cause on site.

Where does the waste go?

It leaves the site with us when we go. While we work, it’s kept contained so the area stays clean.

Staff cleaning versus specialist work

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, and that’s where we come in.

Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.

For landlords and multi-site operators

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.

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
