About our extract fan cleaning in Welwyn
Kitchen extract fans come in different forms: fans on the roof, fans built into the duct run, and fans on an outside wall. Each is isolated and opened in its own way and the survey shows us how to reach it. The work covers roof-mounted fans, discharge points and axial fans, and people most often call us about grease escaping from the fan outlet and hot, greasy smells near the fan.
In a smaller place like Welwyn, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. A kitchen that cooks fewer hours still builds up grease, so cleaning is planned around how much it cooks and what the readings show.
The sign-off is always in writing: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Between visits
Here’s the after-treatment advice, in brief:
- Note any drop in extraction at the canopy
- Listen for new noises or vibration from the fan
- Keep the fan on whenever the range is lit
- Keep records of every fan clean
When we’ve finished, the fan is reassembled and run. Anything we notice, like noise, vibration or a worn part, goes on the report, so you can plan any repair.
Listen to the fan. New noise or vibration often means grease is building on the impeller, and catching it early keeps it a cleaning job.
How the job changes from site to site
Fan housings and motors
We clean around the motor without soaking its electrics, and the fan is isolated throughout. Grease around the motor can make it run hotter, so we clean what we safely can.
Inline duct fans
Hidden in a ceiling void, an inline fan is easily missed. We find it during the survey and include it in the clean.
What extract fan cleaning looks like in Welwyn
Food Standards Agency records include about 11 pubs, bars and clubs in Welwyn and the streets around it, up to about 1.5 miles out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Kitchens in Welwyn get their food hygiene inspections from Welwyn Hatfield council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked. Fire safety in Welwyn falls to Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
A hospital like Queen Elizabeth II Hospital, about 3.5 miles south, is the kind of site where a kitchen may cook for patients, staff and visitors all day. A hall kitchen that only cooks for events, whether near Parish Church of St Mary or elsewhere in Welwyn, still needs its extract cleaned, just less often.
Welwyn is about 2 miles north-west of Welwyn Garden City, in Hertfordshire. Welwyn gets the same approach as every site we work on: a survey first, a fixed quote, work timed around your hours and a report with pictures. Welwyn is one of 381 towns, villages and districts in Hertfordshire we cover for commercial clients. You can also see our page for London, about 23 miles away.
All of AL6 is within our area for extract fan cleaning, from the main roads to the quietest streets. If you need extract fan cleaning at premises on High Street, London Road and Mimram Place or a nearby road, our technicians can take on the work.

The closest station to Welwyn is Welwyn North station, roughly 1.1 miles south-east.

When to call us in Welwyn
Poor filters mean a greasier fan. When filters don’t seal, grease goes straight through to the fan, so the fan takes far more than it should.
Signs it’s time to call us include:
- A fan that has never been cleaned
- A fan that hums, whines or rumbles
- Fat spreading onto the roof or wall by the fan
- A smell of hot grease from the extract
If your kitchen is in a listed or historic building, like the houses around Welwyn (Digswell House is about 0.9 miles south-east), fitting access panels needs care.
Questions to ask before you book
- Whether a written report and pictures are included
- Whether they’re fully insured
- Exactly which parts of the system are covered
- Whether a survey comes first
Welwyn questions
Can the work in Welwyn be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Your opening times are the first thing we ask for.
Do you do school kitchen extract cleaning in Welwyn in the summer holidays?
Yes, out-of-term visits are normal for schools. With about 11 schools and colleges on the FSA’s register within roughly a mile and a half of Welwyn, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
Can you come out in an emergency?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
How do you keep the site clean during the work?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
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. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
What happens if you can’t reach some of it?
Anything we cannot reach goes on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
Why deal with it now?
For a kitchen in Welwyn, a noisy, greasy fan is often the first sign the whole system is overdue. If the fan is coated, the duct before it typically is too, so it’s worth checking the whole system. Booking now means the visit to Welwyn is planned around you, not forced by a breakdown.
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.

Fixed quotes for extract fan cleaning in Welwyn
We quote each job individually. This is what makes a difference:
- Whether it’s a one-off visit or part of a schedule
- Parking and loading at the site
- The times the site is available
- Whether several sites go on one quote
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
What to send for a quote
Before you ask for a quote, gather:
- Close-ups of filters, grilles, hatches or access panels
- The postcode and the type of business
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- When the site is open and when it’s quiet
The quickest way to a quote is to send pictures: 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.
How it works
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the extract fan cleaning, clear away and hand over the paperwork. On site, the work takes an hour or two for most single fans. A site near Welwyn usually has room to park, so the questions are about access to the system and your hours.
- First we check the fan’s condition and how it sounds.
- With the fan isolated, the housing is opened.
- Each blade is cleaned so the impeller runs evenly.
- We clean the casing, the outlet and around the motor.
- The fan goes back into service with a report on its condition.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Agree a time when the area can be out of use
- Have your last certificate or report to hand

For a fixed quote, give us a ring on 0345 646 2711 or email us with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You’ll normally have a quote within one working day.

In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
When your team notices a problem 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.
