About our extract fan cleaning in Westwick Row
A clean fan is not a repaired fan. Anything that looks worn or damaged goes on the report, and we also repair and replace extract fans. You’ll know whether the fan just needed cleaning or something more. The work covers fan housings, roof-mounted fans and in-line fans, and the jobs we see most are grease escaping from the fan outlet and a noisy fan that has got louder over time.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
What extract fan cleaning looks like in Westwick Row
According to Food Standards Agency records, there are about 11 bars, pubs and nightclubs in Westwick Row and the streets around it, up to about 1.5 miles out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Food hygiene inspections in Westwick Row are the job of Dacorum council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready. Westwick Row is covered by Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
If your kitchen is in a listed or historic building, like the houses around Westwick Row (Batchwood Hall is about 3.1 miles north-east), fitting access panels needs care. For schools such as Leverstock Green Church of England Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. If you run a church or community hall kitchen, near Church of Holy Trinity or elsewhere in Westwick Row, its extract still collects grease from every lunch and event.

What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Questions from Westwick Row
Who would carry out a food hygiene inspection at a kitchen in Westwick Row?
Kitchens in Westwick Row are inspected by Dacorum council’s environmental health officers. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Can school kitchens in Westwick Row be cleaned in the holidays?
Yes. The holidays are the usual time for school work. There are about 12 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Westwick Row. Just phone us on 0345 646 2711 or send us an email with your term dates and we’ll plan around them.
Is Westwick Row in your area?
Yes. Our area takes in London and the counties of South East England, and that includes Westwick Row.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
Do we need to close while you work?
Not typically. The area we’re working in has to be out of use while we’re there, so the visit goes in a quiet slot.
Can you come out in an emergency?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Why has my extract fan got louder?
Uneven grease on the impeller often causes it. We clean the fan and tell you if anything else, like worn bearings, is to blame.
Which kinds of sites do you work on?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
What happens on the day
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes a few hours where there are several fans or heavy deposits, and we clear up before we go. A few pictures of the system help us make the most of a visit to a place like Westwick Row.
- The fan is found and its type, access and isolation checked.
- We isolate the power before opening the housing.
- Grease is scraped off the impeller blades and casing.
- Blades, housing and surrounds are degreased with care around the electrics.
- We reassemble, run and photograph the fan.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know about permits to work or site inductions
Getting a quote
To help us quote: where the site is, what it is and its opening hours, a few pictures and the last certificate or report, if there is one. Then phone us on 0345 646 2711, or send details by email.

Fixed quotes for extract fan cleaning in Westwick Row
There’s no set price list, because no two systems are the same. The quote depends on:
- How many systems or sites are involved
- Any permits to work or inductions
- Working hours and out-of-hours timing
- The scale of the work
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before we start.
What to send for a quote
Photos let us diagnose from a distance. Try to include:
- Any previous report or certificate
- Any access panels or hatches you can see
- Problems your staff have spotted
- Wide photos of the system and the area around it
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.

Between visits
Once we have finished, these simple steps help:
- Check filters are seated before cooking
- File the fan’s report with your other records
- Report grease escaping from the fan
- Note any drop in extraction at the canopy
File the photo report with your other extract records. It gives a dated record of the fan’s condition, which helps if anything changes later.
Stick to the interval for the full extract. Regular full cleans keep the fan from building up heavy deposits, in line with BESA guidance.
