Greater London · Extract fan repair and replacement
Brockley Hill extract fan repair
Repair and replacement of kitchen extract fans, fan motors and worn fan parts for businesses, landlords and public buildings in Brockley Hill. CHAS, SafeContractor and ISO 9001, and fully insured.
- A knocking noise from the extract fan
- A fan that keeps cutting out
- A fan that whines, hums or grinds
Aftercare tips
Here’s the after-treatment advice, short and simple:
- Don’t wait for a noisy fan to stop
- Save our number for the 24/7 emergency line
- Keep access to the fan controls unobstructed
- Book regular TR19 cleaning, which includes the fan
Clean filters help a repaired fan stay that way. Less grease on the impeller means less wear and fewer faults.
The fan is part of every full TR19 clean. Keeping grease off the impeller is one of the simplest ways to protect it and that means less wear.
Extract fan repair for kitchens and businesses in Brockley Hill
Think of it as a check-up for the fan: listen to it, diagnose the fault, then treat it. What you want back is a fan that runs smoothly and a plain account of what we found. If you are dealing with a fan that whines, hums or grinds and weak extraction and a smoky kitchen, we can put it right.
Rooftop fans in London take the weather as well as the grease from below, and in time, bearings, belts and motors fail. A fan that is noisy or vibrating is giving a warning.
Insurers, fire officers and environmental health officers all look at records. That is 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.

What a clean won’t put right
To be straight with you, some problems need a different fix:
- Gas interlock faults that a Gas Safe registered engineer must deal with
- Wiring and supply faults beyond the fan itself
- Ductwork designed too small for the kitchen’s cooking
Not sure which it is? You can call 0345 646 2711 or drop us a line and we will tell you honestly.

In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
What affects the cost of extract fan repair
We quote each job individually. This is what makes a difference:
- One-off work versus a regular cycle
- When the work can happen, such as evenings, overnight or weekends
- Access, including roofs, risers and ceiling voids
- How many systems or sites are involved
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before any work starts, so you know where you stand.
Helping us quote
You do not need the technical terms. It helps if you can send:
- Photos showing the whole system and its surroundings
- The paperwork from the last visit, if you have it
- Your opening hours and when the area is out of use
- Close-ups of filters, grilles, hatches or access panels
Need a price for extract fan repair? Please phone us on 0345 646 2711 or send us an email and tell us about the site. We’ll explain what we’d do and send a fixed quote before you commit to anything.
How it works
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. 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 Brockley Hill.
- We agree a time to attend, out of hours if needed.
- We isolate the extract and open the fan housing.
- Bearings, drive, impeller, motor and mounts are inspected.
- You hear whether repair or replacement makes sense, with a fixed quote.
- We complete the work and check the fan runs smoothly.
How to prepare
- Have your last certificate or report to hand
- Mention any sign-in, permit or induction we need
- Name a contact who can let us in at the agreed time
Ask for a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Advice
What we’re called out for in Brockley Hill
Blocked filters and greasy ducts make the fan work harder. A motor that strains runs hot and may cut out or fail.
Clients typically contact us when they notice one of these:
- An extract fan that rattles or knocks
- A motor that trips out or overheats
- Weak extraction and a smoky kitchen
- A whining or grinding extract motor
Occasional-use kitchens, such as a hall kitchen near St Peter or elsewhere in Brockley Hill, are where a stiff or seized fan can turn up.

- Whether the figure could change on the day
- Whether the whole system is included, or only the parts that are easy to reach

Extract fan repair around Brockley Hill
Look up Brockley Hill on the FSA’s food hygiene register and you’ll find about 52 restaurants, cafés and works canteens and about 15 takeaways and sandwich shops in and around Brockley Hill, up to about a mile and a half out. Every one of them that cooks under a canopy depends on its extract fan to keep cooking. Food hygiene inspections in Brockley Hill are the job of Harrow council’s environmental health team. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. That makes a fan repair urgent rather than something to put off. A failed fan in a London kitchen normally means a closed kitchen, so access details help us plan the repair.
If you run a school kitchen, at a school such as London Academy or nearby, a fan that is getting noisy is best repaired in the holidays before it fails in term.

Common questions in Brockley Hill
What if my kitchen extract fan stops in Brockley Hill at night?
Our emergency line runs 24/7, and Brockley Hill is within the area we cover. Use 0345 646 2711, our emergency number, at any time. A photo of the fan’s rating plate helps.
Who inspects food businesses in Brockley Hill?
Kitchens in Brockley Hill are inspected by Harrow council’s environmental health officers. An officer may ask how the kitchen is ventilated, so keep repair records with your maintenance file.
How long will the fan be out of action?
As a guide, it takes a few hours on site, depending on the fault and the access to the fan. If parts have to be ordered, we will tell you how long that’s likely to be.
Are you fully insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Do you look at the system first?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Who is the responsible person?
The Fire Safety Order 2005 calls them the responsible person: often the employer, owner or occupier. Landlords, facilities managers and managing agents can also hold responsibility.
Do I get a report after the visit?
Yes, on every job. It’s a dated, written report with pictures, and TR19® Grease cleans come with a certificate through the BESCA VHE portal. Keep it in your maintenance log.
What happens to the waste?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
