Knightwood: your questions answered
Who inspects food businesses in Knightwood?
Food hygiene inspections in Knightwood are carried out by Eastleigh council. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Do you work in villages like Knightwood?
Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.
Will we have to shut during the visit?
Not typically. Visits are timed for when the area is closed, such as overnight or at a weekend, so the site can carry on as normal.
What accreditations do you have?
Duct Doctor is 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.
Who is responsible for fire safety on the premises?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: normally the employer or whoever controls the premises. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Do you need to turn the fan off to clean it?
We isolate the fan, so the kitchen cannot cook while we work. We work evenings, overnight or weekends, and the kitchen is ready when we leave.
Do you look at the system first?
Yes. We always survey first, from your pictures and details, or with a visit where needed. A fixed quote follows.
How we handle extract fan cleaning in Knightwood
Think of the fan as the system’s heart and the grease as a clot. A greasy fan works harder and moves less air. Our job is to clear it, check it runs smoothly and record what we found so you get a clean bill of health. If you have thick grease on the impeller and casing and a fan that has never been cleaned, we can help, from in-line fans, fan housings and centrifugal fans onwards.
For a smaller kitchen near Knightwood, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. The visit is booked around your opening hours, and the journey is planned ahead.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Fixed quotes for extract fan cleaning in Knightwood
We do not publish a price list, because sites vary so much. The quote depends on:
- One-off work versus a regular cycle
- The number of sites or systems
- The condition we find in the survey
- Working hours and out-of-hours timing
The cost 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 we start, so there are no surprises.
Asking for a quote
We can often survey from pictures. The most useful are:
- Close-ups of filters, grilles, hatches or access panels
- When the site is open and when it’s quiet
- Your last certificate, test record or report
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before we start.
Do you need extract fan cleaning in Knightwood?
How fast a fan gets greasy in Knightwood depends on the cooking: daily hours and the amount of frying and grilling. BESA guidance sets minimum intervals of 3, 6 or 12 months for the whole system by daily use.
What we are most often called out for:
- An extract fan with no cleaning record
- A noisy fan that has got louder over time
- An extract fan that vibrates or rattles
- A heavily greased fan housing
Commuter trade near Chandlers Ford station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.
Questions to ask before you book
- Whether the price is fixed
- When the next visit should be, and why
- What records you’ll receive afterwards
- Proof of accreditation you can verify
The process
Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes a couple of hours per fan, depending on its size and the build-up. Getting to the system matters more than parking in a place like Knightwood, so let us know how to reach it.
- First we locate the fan and agree how it’s safely isolated.
- Power to the fan is isolated before anyone touches it.
- The impeller and the housing around it are scraped clean.
- The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
- It’s closed up, run and checked, and photos go into your report.
How to prepare
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know when the site is closed or quiet
- Dig out any earlier paperwork for the system

In-house cleaning or a specialist?
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Managing agents and facilities teams in Knightwood
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
We also work for facilities teams across offices, schools and healthcare in Knightwood and across Hampshire. Larger estates can be phased building by building around the people who use them.
How the job changes from site to site
Roof-mounted fans
On a roof, the air is cooler and grease drops out faster. The impeller and housing are scraped and degreased.
Impellers and blades
A clean impeller shows any damage: chips, distortion or wear. Anything we see goes on the report.
When something else is needed
We’d rather tell you now than book work that won’t help, so here are the limits:
- A cracked or broken impeller (it needs replacing)
- A fan that will not start
- Grease in the canopy and ductwork
Not sure which it is? You can call us on 0345 646 2711 or send us an email and we will tell you honestly before booking.
