Norcott Hill extract fan cleaning
Extract fan cleaning for Norcott Hill, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.

Extract fan cleaning in Norcott Hill, done properly
Every TR19® Grease clean includes the extract fan, but a fan can also need attention on its own, for example when it’s noisy or vibrating. A fan-only clean is recorded as exactly that. If you’re dealing with fat spreading onto the roof or wall by the fan and a fan coated in grease inside its housing, we can put it right, from in-line fans, centrifugal fans and axial fans onwards.
Work in a small place like Norcott Hill starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Why deal with it now?
A greasy fan at the discharge can spread grease onto the roof or wall around it. That stains surfaces and can add to the fire risk outside the building, which is one more reason to keep it clean. It’s worth booking a check, because nobody sees inside a duct day to day.
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before any work starts.

Aftercare tips
A little care between visits keeps the system in better shape. We recommend:
- Make sure the fan is included each time
- Report rattles or humming early
- Keep access to the fan clear
- Report grease escaping from the fan
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. If only the fan is cleaned, the photo report says so.
Fewer grease particles reaching the fan means less build-up. Clean, well-seated filters are the fan’s first protection, and replace any that are damaged.

Honest limits
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- A fan that is too small for the system (a design question)
- Damaged fan blades
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
If you are not sure, just ring 0345 646 2711, or send details by email and we will give you a straight answer.

Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will go through it with you.
What we need to know
When you call or email, these details help:
- Where the plant sits or the system leaves the building, such as a roof or outside wall

What extract fan cleaning looks like in Norcott Hill
Food Standards Agency records list about 6 cafés, restaurants and staff canteens within about 1.5 miles of central Norcott Hill. Where they cook under a canopy, an extract fan is pulling grease-laden air through its blades every service. In Norcott Hill, food businesses are inspected by environmental health officers from Dacorum council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after photos from each clean are a simple way to show the extract is in hand. The fire and rescue service for Norcott Hill is Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
If you run catering at a historic house or estate in the area (Cholesbury Manor House is about 3.1 miles south-west), event kitchens in older buildings often have awkward duct runs that need planning. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Norcott Hill is Hemel Hempstead Hospital, about 5.9 miles south-east. Term dates shape school work: for a school like St Mary's CofE Primary School, an extract clean fits neatly into a half-term or summer break.

What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
What we do, step by step
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes an hour or two for one fan, longer when it’s hard to reach. Rural roads and tight entrances are worth telling us about before a visit to Norcott Hill.
- 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.
- It’s closed up, run, checked and photographed for the report.
Getting ready for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us the best time to work, such as after service or at a weekend
- Tell us about site rules, permits or sign-in

Norcott Hill questions
Do you work overnight in Norcott Hill?
Yes. We work evenings, overnight and at weekends. That way a site in Norcott Hill does not have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Can you clean school kitchen extracts in Norcott Hill during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 3 schools, colleges and universities with registered kitchens within about a mile and a half of Norcott Hill. Just ring 0345 646 2711 or use the quote form with your term dates and we will plan around them.
What’s the cleaning interval for an extract fan?
It’s cleaned with the whole extract at BESA’s minimum intervals for your cooking hours. Grease readings and the fan’s condition can show it needs more.
Who has the legal duty for fire safety?
The Fire Safety Order 2005 calls them the responsible person: normally the employer or whoever controls the premises. Landlords, facilities managers and managing agents can also hold responsibility.
What makes a kitchen extract fan vibrate?
Build-up on the impeller is a frequent reason, because it unbalances the fan. It can also be wear in the bearings or motor, which our report will flag.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Do you provide a report after cleaning the fan?
A photo report, including the fan’s condition and the next clean date. File it with your other extract records.
