Extract fan repair in Hatfield
Grease and fans don’t mix. Deposits on the impeller throw it out of balance and the vibration wears out bearings and fixings. So when we repair extract fan, we look at the grease too and can arrange a TR19® clean of the whole system at the same time. We’re often asked to deal with a worn or slipping fan belt and a knocking noise from the extract fan, across roof and wall fans, fan motors and belts and pulleys.
Extract fans on buildings in towns like Hatfield are often on a flat roof or an outside wall, exposed to wind and rain as well as grease. In time, belts, bearings and motors wear.
Nothing is signed off by word of mouth: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Extract fans in Hatfield
Food Standards Agency data counts about 65 restaurants, cafés and works canteens and about 28 takeaways within about 1.5 miles of central Hatfield. Every one of them that cooks under a canopy depends on its extract fan to keep cooking. In Hatfield, food businesses are inspected by environmental health officers from Welwyn Hatfield council. Under food hygiene rules, a kitchen needs suitable and sufficient ventilation. That makes a fan repair urgent rather than something to put off. We cover Hatfield, about 19 miles from central London, as part of our work across London and the South East. The visit is fixed around your opening hours, not ours.
If you cook near Hatfield station, long trading hours wear fan belts and bearings, so noise and vibration are worth reporting early. A fan that rarely runs, like one in a hall kitchen near Church of St Luke or elsewhere in Hatfield, can seize between uses.
Hatfield is about 4 miles east of St Albans, in Hertfordshire. From the centre of Hatfield to the outskirts, extract fan repair is available to all kinds of commercial premises, from a single unit to a large public building. Hatfield is one of 381 towns, villages and districts in Hertfordshire where we work for commercial clients. You can also see our page for London, about 19 miles away.
Every address in AL10 and AL9 is covered for extract fan repair, from the main roads to the quietest streets. Local streets include Market Place, Bishop Square and Fiddle Bridge Lane, all of which we cover for extract fan repair. Hatfield sits on or near the A414 and B197, which makes travel easy for evening and night visits. Neighbouring places we cover for extract fan repair include Smallford (2 miles west), Colney Heath (2 miles south-west), Sleapshyde (2 miles south-west), Stanborough (2 miles north) and Cooper's Green (2 miles north-west). Within a short drive, we also cover Watford (10 miles south-west), Hemel Hempstead (10 miles west), Stevenage (10 miles north), St Albans (4 miles west), Welwyn Garden City (3 miles north-east) and Harpenden (6 miles north-west).

In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
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.
Common problems we fix in Hatfield
Grease that gets past the filters ends up on the fan. It builds up on the impeller blades unevenly, so the fan runs out of balance and the noise follows.
Most sites get in touch when they notice one of these:
- A dead fan motor
- A failed fan that needs a replacement
- A squealing belt on start-up
- Poor airflow at the canopy
For school kitchens, at schools like Bishop's Hatfield Girls' School for example, a planned fan repair in the holidays avoids losing lunches in term time.
Comparing quotes
- Whether they’re fully insured
- Whether inaccessible sections are listed on the report
- When the next visit should be, and why
- If the quote is a fixed price or an estimate
When it’s something else
Not every problem is solved by extract fan repair, and we will tell you before we start. It will not put right:
- Problems with the electrical supply to the fan (an electrician’s job)
- Gas interlock faults that a Gas Safe registered engineer must deal with
- Odour complaints that need filtration rather than a fan repair
If you’re not sure, just phone us on 0345 646 2711 or email us and we’ll give you a straight answer before you book.

What affects the cost of extract fan repair
There’s no set price list, because sites vary so much. What we look at:
- Site requirements such as sign-in and permits
- Whether it’s a one-off visit or part of a schedule
- The size of the system
- Where the site is and how we reach it
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will explain each part.
What we need to know
What to send for a quote:
- Wide pictures of the system and the area around it
- When the site is open and when it’s quiet
- The postcode and the type of business
- Any symptoms, from odd noises to smells or leaks
Photos are the quickest way to a quote: 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.
The process
Your staff don’t need to do much 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. Parking in a town like Hatfield is usually straightforward, so the main questions are access and timing.
- You describe the fault and we arrange a visit.
- We isolate the fan before touching it.
- We diagnose the fault, checking the controls as well as the fan.
- A fixed quote for the repair or replacement follows.
- The work is done and the fan is tested running.
How to prepare
- Arrange a key holder or contact on site
- Clear loose items from the work area
- Find the previous report, if there is one
Getting a quote
To get a fixed quote, call 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. We normally come back within one working day.

Questions from Hatfield
Who carries out food hygiene inspections in Hatfield?
Kitchens in Hatfield are inspected by Welwyn Hatfield council’s environmental health officers. Inspections are risk-based, so a visit can come at any time, including the week a fan stops.
Can you come out to a failed extract fan in Hatfield out of hours?
Extract fan emergencies in Hatfield are covered around the clock. Phone 0345 646 2711 and we will talk through the fault and access. Let us know whether the fan is silent, noisy or tripping the power.
How much notice do you need?
For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
Will I get paperwork for my records?
Yes, on every job. The report is dated and includes pictures, plus a certificate via the BESCA Vent Hygiene Elite portal for TR19® Grease cleans. Keep it in your maintenance log.
What should go in our maintenance log?
Visit reports, certificates and your in-house cleaning logs. They’re what an insurer, fire officer or EHO may ask for, so keep them together and easy to find.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. At the end, the area is cleaned down.
Is it worth cleaning the extract while you are fixing the fan?
The ductwork is a separate job. We will point out grease where we find it and quote for a TR19 clean if it’s needed.
Why act early in Hatfield
Where the cooking gas supply is interlocked with the extract, a failed fan can stop the kitchen cooking. Even without an interlock, cooking without extraction is not sensible and fixing the fan early avoids a forced shutdown. A fresh certificate on file is the best thing to have when someone asks to see your records.
What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before any work starts.
