Your questions about extract fan repair in Barnehurst
Can you work in Barnehurst outside opening hours?
Yes, nights and weekends are routine for us. That way a site in Barnehurst doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
Which council inspects kitchens in Barnehurst?
That’s Bexley council, whose environmental health officers carry out food hygiene inspections in Barnehurst. Keeping the fan serviced is easier than explaining a broken one on inspection day.
Does a faulty extract fan always need replacing?
In many cases, yes. Many faults are fixed by cleaning the impeller or renewing worn parts, and we’ll always say when repair makes sense.
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.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Is Barnehurst in your area?
Yes. Our area takes in London and the counties of South East England, and that includes Barnehurst.
Do you offer maintenance contracts?
Yes, of course. Send details of the systems and how they’re used, and we’ll suggest a schedule and quote for it.
Which accreditations do you hold?

How we handle extract fan repair in Barnehurst
Wherever your kitchen is in Barnehurst, fan work means the extract has to be isolated, so we plan it around your service. We can work in the evening, overnight or at the weekend, and a fan that dies mid-service can go straight to our 24/7 line. Common call-outs are for a belt-driven fan that squeals and an extract fan that rattles or knocks, on fan motors, bearings and kitchen extract fans.
Rooftop fans in London take the weather as well as the grease from below, and bearings, belts and motors wear out in the end. Noise and vibration are worth reporting before the fan stops.
We have been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows.

- A visit is booked, in the evening or overnight if that suits.
- The extract is switched off and the fan opened up.
- We inspect every moving part and the fixings.

What we’re called out for in Barnehurst
Some grease always slips past the filters and reaches the fan. It builds up on the impeller blades unevenly, and an unbalanced impeller shakes and the noise follows.
It’s time to book a visit if you see:
- An extract that vibrates through the ductwork
- A fan that keeps cutting out
- A belt-driven fan that squeals
- A dead fan motor
Hall kitchens near Church of St Paulinus, or anywhere around Barnehurst, often use their fans only now and then, and an idle fan can stick.

What extract fan repair cannot fix
We’d rather tell you now than book work that will not help, so here are the limits:
- Ductwork designed too small for the kitchen’s cooking
- Grease throughout the ductwork, which needs a full TR19 clean
- Odour complaints that need filtration rather than a fan repair

Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.

What affects the quote in Barnehurst
The price is fixed before any work begins. It’s based on:
- How big the system is
- The number of sites or systems
- A single visit or a regular plan
- When the work can happen, such as evenings, overnight or weekends
We don’t list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.
What to send for a quote
You don’t need the technical terms. It helps if you can send:
- Wide pictures of the system and the area around it
- The site address and the type of premises
- Any access panels or hatches you can see
- How we’d reach plant on a roof or in a plant room
The quickest way to a quote is to send photos: 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.
Why act early in Barnehurst
An overloaded motor is under constant strain. Every hour of strain takes its toll, and when it finally fails, it may take other parts with it. Early attention keeps the cost and disruption down. London sites work long hours, and the longer a job is left, the bigger it gets.
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 any work starts.

What your team can do, and what needs us
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.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
