Extract fan cleaning in Southsea, done properly
The fan is cleaned as part of every full TR19® Grease clean, but some fans need cleaning between full cleans, for example when it’s noisy or vibrating. Where only the fan is cleaned, the report says so. The work covers in-line fans, fan housings and axial fans, and common reasons people get in touch are a motor area thick with grease and a heavily greased fan housing.
Most kitchens in a town like Southsea cannot close for a day, so cleans are booked after closing, early in the morning or on a quiet day. The kitchen is handed back clean and ready to cook.
Nothing is signed off by word of mouth: 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.

Managing agents and facilities teams in Southsea
We regularly work with managing agents. Send the address, what’s needed and how access works and we will come back with a fixed quote.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.

Signs you need extract fan cleaning in Southsea
Each blade collects a slightly different amount. Over time, that imbalance shakes the fan, wearing bearings and mounts. What starts as a grease problem can become a mechanical one.
Keep an eye out for these warning signs:
- Vibration from an unbalanced impeller
- Hot, greasy smells near the fan
- Fat spreading onto the roof or wall by the fan
- Rough running from the extract fan
School kitchens, at schools like Craneswater Junior School for example, are usually cleaned in the holidays so no lunches are lost.

What we do, step by step
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before any work starts, and the area around the work is covered and protected. The work itself takes a couple of hours per fan, depending on its size and the build-up. Send us pictures of the system and we can plan most of a visit in Southsea before we arrive.
- The fan is found and its type, access and isolation checked.
- It’s isolated so it can’t run while we work.
- Grease is scraped off the impeller blades and casing.
- The fan is degreased, taking care around the motor.
- We reassemble, run and photograph the fan.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure someone can let us in and lock up afterwards

Advice
Part by part
Inline duct fans
Inline fans sit within the duct run, often above a ceiling. They’re reached through access panels or by opening the casing after isolating them.
Roof-mounted fans
On a roof, the air is cooler and grease drops out faster. We scrape and degrease the blades and casing.
Leave it or put it right?
A fan clean in Southsea does not take long: it takes a couple of hours per fan, depending on its size and the build-up. Leaving it means more wear, more noise and a bigger clean later. If an inspection, an insurer’s survey or a fire risk assessment is coming up in Southsea, having the work done and recorded first helps.
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.
Why us?
- Evenings, overnight and weekends, plus 24/7 emergency callout
- Fixed quotes from a survey or pictures

Questions from Southsea
Which fire authority looks after Southsea?
Hampshire and Isle of Wight Fire and Rescue Service is the fire and rescue service for Southsea. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Do you work at weekends in Southsea?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Let us know the hours you are closed and we’ll book within them.
Is it safe to clean the fan while the kitchen is open?
The fan must be isolated, for safety. We clean out of hours, in the evening, overnight or at weekends, so cooking is not affected.
Do you survey before quoting?
Yes. Photos often do the job, and larger or hidden systems get a visit.
Do you offer emergency callouts?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we’ll advise on what to do next.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
Who has the legal duty for fire safety?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: often the employer, owner or occupier. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
Extract fan cleaning around Southsea
Sea air reaches Southsea, 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 data shows about 78 pubs, bars and clubs and about 20 hotels and B&Bs registered across Southsea and its immediate surroundings (about a mile and a half). Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Fire safety in Southsea falls to Hampshire and Isle of Wight Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
If you cook for passing trade around Fratton station, the extract can be cleaned between your last and first customer. A hospital like St. Mary's Hospital, about 1 mile north, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Check the report shows the fan was cleaned
- Watch for grease marks around the outlet
- Listen for new noises or vibration from the fan
- Keep the grease filters clean and in place
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. A fan-only clean is recorded in the photo report.
The fan stays cleaner when less grease gets past the canopy. Clean, well-seated filters are the fan’s first protection, and replace any that are damaged.
What affects the cost of extract fan cleaning
The diagnosis comes before the price. The main factors are:
- Working hours and out-of-hours timing
- The number of sites or systems
- Any permits to work or inductions
- How big the system is
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we’ll price it together.
What to send for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- The roof, plant room or outside wall the system runs to
- The times we could work without disrupting the site
- Any access panels or hatches you can see
- A few general shots of the system
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
