How we handle extract fan cleaning in Alverstoke
Duct Doctor has been cleaning kitchen extract fans since 2009. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, with CHAS, SafeContractor and ISO 9001 and full insurance. If you have rough running from the extract fan and fat spreading onto the roof or wall by the fan, we can help, from discharge points, axial fans and in-line fans onwards.
For a kitchen in or near Alverstoke, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What extract fan cleaning looks like in Alverstoke
Sea air reaches Alverstoke, which sits within about 1 mile of the coast. Corrosion on the fan housing and cowl is worth a look at every clean, alongside the grease. The FSA’s food hygiene register includes about 27 bars, pubs and nightclubs and about 3 hotels, B&Bs and guest houses in Alverstoke and the streets around it, up to about 1.5 miles out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Alverstoke sits within the area of Hampshire and Isle of Wight 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.
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Alverstoke is Gosport War Memorial Hospital, about 0.9 miles north. Bursars and site managers at schools such as Alverstoke Community Infant School tend to book extract cleaning for when the kitchen is empty.
Alverstoke is about 2 miles south of Gosport, in Hampshire. We provide extract fan cleaning for commercial premises of every kind in Alverstoke and the rest of Hampshire. Alverstoke is one of 683 towns, villages and districts in Hampshire we cover for commercial clients.

Looking after it afterwards
Simple habits between visits make a real difference. Our advice:
- Run the extract throughout cooking
- Listen for new noises or vibration from the fan
- Check filters are seated before cooking
- Make sure the fan is included each time
You get before and after pictures of the impeller and housing. It notes what was done and anything that couldn’t be reached, along with the recommended next clean date.
Do not run the kitchen with the extract off. Air that keeps moving carries vapour out rather than letting it settle, so keeping it running helps keep it clean.
Different parts, different methods
Roof-mounted fans
Roof fans sit at the top of the riser. They’re cleaned where safe access allows, with any limits noted.
Inline duct fans
Space around an inline fan can be tight, so the method is planned in advance. Anything out of reach is recorded.
Your questions about extract fan cleaning in Alverstoke
Do you do school kitchen extract cleaning in Alverstoke in the summer holidays?
Yes, holiday work suits schools best. There are about 20 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Alverstoke. Send us your term dates when you call 0345 646 2711 or email us, and we’ll fit the work in.
Which fire service covers Alverstoke?
Hampshire and Isle of Wight Fire and Rescue Service is the fire and rescue service for Alverstoke. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Is TR19 cleaning required by law?
No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Who is the responsible person?
That depends on who controls the premises. Under the Fire Safety Order 2005, it’s the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
Which sectors do you work in?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
Is Alverstoke in your area?
Yes. We cover Alverstoke and across Hampshire, as part of our work across South East England and London. To book, call 0345 646 2711, or send details by email.
Do we lose a day’s trading?
Not usually. We need the work area to ourselves while we are on site, so the visit goes in a quiet slot.
What makes a kitchen extract fan vibrate?
Often it’s grease on the impeller. Grease collects unevenly and unbalances the impeller, causing vibration and noise. If cleaning does not, the bearings or motor may need attention.
For landlords and multi-site operators
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
In-house cleaning or a specialist?
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
How we price extract fan cleaning
There’s no set price list, because no two systems are the same. The quote depends on:
- The number of sites or systems
- Parking and loading at the site
- Access, including roofs, risers and ceiling voids
- Any permits to work or inductions
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
What we need to know
Before you ask for a quote, gather:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Photos showing the whole system and its surroundings
- Detail shots of panels, filters and grilles
- Any previous report or certificate
To get a fixed quote, ring 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You will typically have a quote within one working day.
Common problems we fix in Alverstoke
A fan in Alverstoke builds up grease at a rate set by the kitchen, not the location: how many hours a day the kitchen runs and what it cooks. BESA guidance sets minimum intervals of 3, 6 or 12 months for the whole system by daily use.
These are the problems we see most often:
- An extract fan that vibrates or rattles
- Rough running from the extract fan
- Grease stains around the discharge
- A smell of hot grease from the extract
Volunteers running a hall kitchen near The Little Church, or anywhere in Alverstoke, may not know when the extract was last cleaned, and a grease test settles it.
What to look for in a quote
- Proof of insurance
- Whether they recommend a next date
- Whether a survey comes first
- What records you’ll receive afterwards
What happens on the day
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Rural roads and tight entrances are worth telling us about before a visit to Alverstoke.
- We find the fan and check how it’s reached and how it’s isolated.
- The fan is isolated so it cannot start while we work.
- The impeller and the housing around it are scraped clean.
- Blades, housing and the area around the motor are degreased with care.
- The fan is put back into service, checked and photographed.
How to prepare
- Make sure someone can let us in and lock up afterwards
- Let us know how we reach the system, including roofs, risers and plant rooms
- Clear the space around the work
How to get a quote
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To start, phone us on 0345 646 2711, or send details by email.
