Extract fan repair in North Harrow, done properly
Not every failed fan needs replacing. Sometimes cleaning the impeller or renewing worn parts is enough, and that is what we will recommend. Where the motor has burnt out or the unit is past saving, a replacement suited to the system goes in. If you’re dealing with a belt-driven fan that squeals and an old fan that needs replacing, we can put it right.
In London, getting a new fan to the roof or plant room can take planning, and in North Harrow, parking and lifting are part of that. Repairs can be done out of hours so the kitchen keeps trading.
A written report with pictures follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Between visits
A little care between visits keeps the system in better shape. Our advice:
- Don’t wait for a noisy fan to stop
- Do not turn the fan down to hide a noise
- Make sure the fan is cleaned with the rest of the system
- Never run the extract with filters missing
Before we leave, the fan is run and checked. You’ll hear what we found and what we did along with anything else that needs watching.
A 3, 6 or 12-monthly cleaning plan brings us back at set intervals, which means the fan is seen regularly and wear is caught earlier.
Fixed quotes for extract fan repair in North Harrow
Sites vary more than people expect. What affects the quote:
- Whether it’s a one-off visit or part of a schedule
- The condition of the system
- Parking and loading at the site
- Site requirements such as sign-in and permits
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
Asking for a quote
Before you ask for a quote, gather:
- The times we could work without disrupting the site
- The postcode and the type of business
- Wide pictures of the system and the area around it
- The paperwork from the last visit, if you have it
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
When a fan fails in North Harrow
The FSA’s food hygiene register shows about 272 restaurants, cafés and canteens and about 118 sandwich bars and takeaways across North Harrow and its immediate surroundings (about a mile and a half). Those that cook under a canopy rely on a fan that runs every hour they’re open. Kitchens in North Harrow get their food hygiene inspections from Harrow council. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. That is one more reason not to keep cooking with a broken fan. We ask about access first for a London fan job, because roofs and basements need planning.
A fan that rarely runs, like one in a hall kitchen near Church of St Alban or elsewhere in North Harrow, can seize between uses. For school kitchens, at schools like Longfield Primary School for example, a planned fan repair in the holidays avoids losing lunches in term time.

North Harrow: your questions answered
Do you work overnight in North Harrow?
Yes. We work evenings, overnight and at weekends. The work in North Harrow can fit around your hours. Just phone us on 0345 646 2711 or send us an email with your opening times and we will plan around them.
How do you handle parking and loading in North Harrow?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Working overnight, as we often do in London, usually makes it simpler.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before work begins, and waste is contained as we go. At the end, the area is cleaned down.
Can we book visits on a schedule?
Yes, of course. Send details of the systems and how they’re used and we will propose a schedule with a fixed quote.
Is repair an option before replacing the whole fan?
It depends on the fault. We diagnose first and tell you whether a repair is realistic, then give you a fixed quote.
Do you provide a certificate or report?
Yes. You get a written report with photos after each visit, covering the work, any areas we couldn’t access and the recommended next date. Kitchen extract cleans to TR19® Grease also get a certificate through the BESCA Vent Hygiene Elite portal.
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 the job changes from site to site
Impellers and housings
Where an impeller is bent or corroded, cleaning will not help. It may need replacing, or the fan may need replacing as a whole.
Belt-driven fans
In a belt-driven fan, the motor drives the impeller by belt. Worn belts squeal and slow the fan down, so we check the pulleys and bearings as well.
In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Also in North Harrow
Leave it or put it right?
In kitchens with an interlocked gas supply, no extract can mean no cooking. Even without an interlock, cooking without extraction is not sensible and fixing the fan early avoids a forced shutdown. A booked night’s work in North Harrow costs you no trading time; an unplanned closure does.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before we start.

Multi-site and managed buildings
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
The process
A visit follows the same order every time: protect the area, make the system safe, carry out the extract fan repair, clear away and hand over the paperwork. The visit itself takes a few hours on site, depending on the fault and the access to the fan. For a job in North Harrow, tell us about loading bays, permits, lifts and roof access when you book.
- First, you tell us the symptoms: noise, shaking, weak extraction or no power.
- Power to the fan is isolated before we open the housing.
- The impeller, bearings, belts or drive, motor and mounts are all inspected.
- You get our diagnosis and a fixed quote to repair or replace.
- Once the work is done, we run the fan and check it’s steady and quiet.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Clear the space around the work
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Get a fixed quote
Getting a quote doesn’t take long. Send a few details and photos, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
