Extract fan repair for kitchens and businesses in Bow
Everything a kitchen extract does depends on the fan. When it starts to rattle, hum or slow down, the kitchen gets hot and smoky very quickly. Our engineers track down the fault and fix it, by repairing the fan or replacing it. The work covers kitchen extract fans, roof and wall fans and belts and pulleys, and common reasons people get in touch are a fan running too slowly to clear the kitchen and a whining or grinding extract motor.
Replacing a fan in a London building often means working at height or in a tight plant space, and in Bow, parking and lifting are part of that. Work can be done after service, so the kitchen loses as little time as possible.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

When a fan fails in Bow
There are about 539 cafés, restaurants and staff canteens and about 177 takeaways and sandwich shops within 1.5 miles or so of the middle of Bow, according to the Food Standards Agency’s register. Those that cook under a canopy rely on a fan that runs every hour they’re open. It’s Tower Hamlets council that sends environmental health officers to food businesses in Bow. Food hygiene rules expect food premises to have suitable and sufficient ventilation. That is one more reason not to keep cooking with a broken fan. A failed fan in a London kitchen normally means a closed kitchen, so access details help us plan the repair.
Holidays are the time to replace a tired kitchen fan at schools such as Old Ford Primary - A Paradigm Academy, rather than mid-term. For kitchens close to Hackney Wick station, a fan that stops mid-service needs fixing fast, and our emergency line runs 24/7.

Around Bow
In Bow, that means kitchens and buildings near Lord Tredegar Public House, Grove Hall Park and Mulberry UTC. For rail, the closest station is Hackney Wick station, about 0.9 miles north of the centre.

What happens if it’s left?
Weak extraction leaves heat, smoke and fumes in the kitchen. Staff work in hotter, steamier air, and more grease settles where it shouldn’t. Every month a London system goes without attention adds to what has to be done later.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.

What staff can safely do
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.

Your questions about extract fan repair in Bow
Can you come to Bow after we close?
Yes, out-of-hours work is a big part of what we do. The work in Bow can fit around your hours. Just give us a ring on 0345 646 2711 or drop us a line with your opening times and we will plan around them.
Is there an emergency callout for extract fans in Bow?
Bow is covered, and our emergency callout runs 24/7. Use 0345 646 2711, our emergency number, at any time. A photo of the fan’s rating plate helps.
Do you replace extract fans as well as repair them?
Yes. Where a fan is beyond repair, we replace it with one suited to the duct and the kitchen, and you get a fixed quote first.
Do you provide a certificate or report?
Yes. It’s your proof that the work was done: a dated report with pictures, listing the work and any areas we couldn’t reach.
Which records should we keep?
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.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
How long will the fan be out of action?
That depends on what’s wrong, but most jobs take part of a day for most faults, with a return visit if parts have to be ordered. We’ll give you a better idea once we’ve diagnosed it.
What will a fan repair or replacement cost?
It depends on the fault, the parts and the access. After diagnosing, you get a fixed quote so there are no surprises.
Between visits
Think of this as the after-treatment advice, in brief:
- Do not turn the fan down to hide a noise
- Make sure the fan is cleaned with the rest of the system
- Keep access to the fan controls unobstructed
- Keep a record of any trips or stoppages
Listen to the fan over the next few weeks. If anything changes, let us know rather than waiting for it to fail.
A 3, 6 or 12-monthly cleaning plan brings us back at set intervals, so the fan is looked at as part of each visit and problems are spotted sooner.
Managing agents and facilities teams in Bow
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
The process
Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Getting kit into a London building takes planning, so let us know where we can load and park in Bow.
- We agree a time to attend, out of hours if needed.
- The extract is switched off and the fan opened up.
- We inspect every moving part and the fixings.
- You hear whether repair or replacement makes sense, with a fixed quote.
- We complete the work and check the fan runs smoothly.
Before we arrive
- Name a contact who can let us in at the agreed time
- Move anything stored near the system
- Let us know how we reach the system, including roofs, risers and plant rooms
Ask for a quote
To get a fixed quote, call us on 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You’ll normally have a quote within one working day.

Signs you need extract fan repair in Bow
Grease that gets past the filters ends up on the fan. Deposits gather on the blades, never quite evenly, and an unbalanced impeller shakes and the noise follows.
Clients typically contact us when they notice something like this:
- A fan that whines, hums or grinds
- A fan running too slowly to clear the kitchen
- A fan shaking on its mountings
- A worn or slipping fan belt
Occasional-use kitchens, such as a hall kitchen near St Paul Old Ford or elsewhere in Bow, are where a stiff or seized fan can turn up.
