How we handle extract fan cleaning in Sopwell
Not all extract fans are the same: fans on the roof, fans built into the duct run, and fans on an outside wall. The way in depends on the type, and we plan that during the survey. If you have a fan motor running hot under a coat of grease and grease escaping from the fan outlet, we can help.
Around a smaller place like Sopwell, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.
Each visit ends with a written report and pictures, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What a clean will not put right
A few issues sit outside what this work can do:
- A failed motor or worn bearings (that needs a fan repair or replacement)
- A dirty duct upstream of the fan
- An impeller that’s bent or split

What happens on the day
Each visit runs to the same pattern: protect the area, make the system safe, do the work, tidy up and hand over the paperwork. The visit itself takes a couple of hours per fan, depending on its size and the build-up. Around Sopwell, access is normally simpler than in a town centre, though gates and roof access are worth mentioning.
- We find the fan and check how it’s reached and how it’s isolated.
- With the fan isolated, the housing is opened.
- The impeller and the housing around it are scraped clean.
- We degrease the fan and housing, taking care around the motor.
- We reassemble, run the fan and photograph the result.
How to prepare
- Clear loose items from the work area
- 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

Grease, kitchens and Sopwell
Look up Sopwell on the FSA’s food hygiene register and you’ll find about 147 restaurants, cafés and canteens and about 41 takeaways within 1.5 miles or so of the middle of Sopwell. Each kitchen extract among them ends at a fan, and grease on the impeller strains the motor. Sopwell sits within the area of 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. Food hygiene inspections in Sopwell are the job of St Albans City council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after.
School kitchens, at schools like Mandeville Primary School for example, are usually cleaned in the holidays so no lunches are lost. If you cook for passing trade around St Albans Abbey station, the extract can be cleaned between your last and first customer.
Sopwell is about 1 mile south of St Albans, in Hertfordshire. Across the AL1 area, we cover extract fan cleaning for commercial sites. Across Hertfordshire, we cover 381 places, and Sopwell is one of them. Our London page covers sites nearby, about 19 miles away.
Work in AL1, AL2 and AL3 is surveyed, quoted and booked the same way as anywhere else. Local streets include Nuns Lane, Jenny Lane and Vesta Avenue, and we cover them all for extract fan cleaning. If your site is just outside Sopwell, we cover St Stephens (1 mile north-west), St Albans (1 mile north), Park Street (1 mile south), Chiswell Green (1 mile south-west) and Frogmore (1 mile south).

What we’re called out for in Sopwell
A greasy fan in Sopwell is fuel at the end of the duct. If grease in the duct catches, the fan and its housing can feed the fire and an overworked motor runs hotter.
Keep an eye out for these warning signs:
- Vibration from an unbalanced impeller
- Burning smells from the fan area
- Rough running from the extract fan
- An extract fan with no cleaning record
A hall kitchen that only cooks for events, whether near St. Julian's Church or elsewhere in Sopwell, still needs its extract cleaned, just less often.
What your quote should include
- Whether inaccessible sections are listed on the report
- Whether the quote is based on a survey or pictures
- Proof of insurance
- Whether VAT is included
Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

Aftercare tips
Once we’ve finished, these simple steps help:
- Keep access to the fan clear
- Make sure the fan is included each time
- Keep each photo report with the maintenance log
- Note any drop in extraction at the canopy
The photo report shows the fan before and after cleaning. It notes what was done and anything that couldn’t be reached, along with the recommended next clean date.
A change in how the fan sounds is worth noting. Rattles, hums or shaking can be early signs of build-up or wear and early action can save a repair.
FAQs for Sopwell
Do you work overnight in Sopwell?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Sopwell needn’t be disturbed. When you call 0345 646 2711, or send details by email, mention when the site is quiet.
Which fire authority looks after Sopwell?
It’s Hertfordshire Fire and Rescue Service, which covers Sopwell. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Do we lose a day’s trading?
Normally not. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits to keep things running.
Do you offer maintenance contracts?
Yes, of course. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
Do you provide a report after cleaning the fan?
You get a photo report with before and after photos of the fan. Full system cleans come with a TR19 certificate as well.
Do you repair extract fans as well as clean them?
Cleaning removes grease, but it cannot fix worn parts. We repair and replace extract fans as well, with a fixed quote first.
Who is the responsible person?
The law calls them the responsible person. It’s normally the employer, or whoever controls the building, and where several people have control, each can have duties. If you’re not sure, check your lease and fire risk assessment.
Why deal with it now?
Grease on the impeller makes the fan less efficient. Airflow at the canopy drops and the kitchen gets hotter and smokier and the motor works harder. Around Sopwell, a kitchen or building out of action is missed straight away.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
