Ventilation duct cleaning in Northney
Every ventilation system has ducts bringing air in and ducts taking it out. Over time, both collect dust and debris, and some of it is blown back into the building. Our cleaning covers the ducts, grilles and diffusers, to TR19® Air. The work covers offices and schools, general extract ductwork and toilet extract systems, and people most often call us about ductwork that hasn’t been inspected and dust marks around grilles and ceiling diffusers.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What happens on the day
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes anything from a single shift for a small office to a planned programme of nights for a large building. In a small place like Northney, the journey is planned ahead and the visit arranged around the site’s hours.
- First the system is surveyed, on site or from photos and drawings.
- Inspection comes next, with photos of the inside of the ducts.
- We protect the rooms beneath and switch the system off.
- We clean the ductwork, grilles and diffusers through access panels.
- You get a TR19® certificate and photo report, with any unreached sections noted.
Before we arrive
- Move anything stored near the system
- Have your last certificate or report to hand
- Plan for cooking equipment or plant to be off before we arrive

Questions from Northney
Is Northney in your area for ventilation duct cleaning?
Yes, we work in Northney and the places around it. A fixed quote usually follows within one working day of the survey details.
Do you work overnight in Northney?
Yes, nights and weekends are routine for us. It means the site in Northney keeps running as normal. Your opening times are the first thing we ask for.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
Does the law say we must follow TR19?
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 cleaning to TR19® is the recognised way to show grease is under control.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Each site gets its own report and pictures.
Are grilles and diffusers included?
Yes, along with the ducts behind them. You’ll see them in the before and after photos.
What if parts of the system cannot be reached?
We record them on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
Different parts, different methods
Grilles and diffusers
Grilles and diffusers are where the ducts meet the room. We clean them as part of the job, so the room side matches the duct side.
Hospitals and care homes
Hospitals and care homes are occupied day and night. The work is sequenced with staff so care carries on.
What ventilation duct cleaning cannot fix
Before you book, it helps to know what’s not included:
- Leaks from roofs, pipes or walls into the ductwork
- Ventilation that is undersized for the building
- Problems with how the system is controlled
If in doubt, phone us on 0345 646 2711 or drop us a line and we’ll say what we think before booking.
What we work on in Northney
- Offices and schools
- Supply ductwork
- Grilles and diffusers
- Hospitals and care homes
- Toilet extract systems
- General extract ductwork
Leave it or put it right?
Leave dust in the ductwork and it keeps building. The longer it’s left, the more there is to remove, and the more gets blown back into the rooms. In a place like Northney, ductwork and fans are easy to forget until something goes wrong.

Fixed quotes for ventilation duct cleaning in Northney
The quote reflects the site in front of us. We consider:
- Site requirements such as sign-in and permits
- Working hours and out-of-hours timing
- Where the site is and how we reach it
- One-off work versus a regular cycle
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before any work starts.
What we need to know
When you contact us, it’s useful to have:
- Your opening hours and when the area is out of use
- Any access panels or hatches you can see
- The paperwork from the last visit, if you have it
- The roof, plant room or outside wall the system runs to
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
What ventilation duct cleaning looks like in Northney
Food Standards Agency records list about 5 hotels, B&Bs and guest houses registered as food businesses within about 1.5 miles of central Northney. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Northney is about 60 miles from central London, well within the area we cover across London and the South East. The visit is fixed around your opening hours, not ours. About 2.1 miles north-west of Northney is Havant War Memorial Hospital, the nearest hospital. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
Wherever a school like Warblington School has ducted ventilation, a half-term visit keeps the work out of lesson time. If you run a surgery, dental practice or care home near Northney, clean ventilation matters as much to you as to a hospital like Havant War Memorial Hospital (about 2.1 miles north-west).
Northney is about 3 miles south-east of Havant, in Hampshire. We provide ventilation duct cleaning for businesses, landlords and public buildings in Northney and the rest of Hampshire. Northney is one of 683 towns, villages and districts in Hampshire we cover for commercial clients.

Local landmarks in Northney
Around Northney, our work takes us to kitchens and buildings near Eames Farm and The Ship Inn and the streets around them. For rail, the closest station is Warblington station, roughly 1.7 miles north of the centre.

What staff can safely do
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Switch the ventilation off or cover grilles during dusty building work
- Include grilles in the cleaning rota
- Tell your facilities team about dirty diffusers
- Stick to the filter change schedule
We recommend when the system should next be inspected, in line with the risk-based approach of TR19® Air. Put it in the diary now so it is not missed.
Make sure there are enough access panels to inspect and clean the ducts. The worst build-up tends to be where no one can look.
