What affects the cost of ventilation duct cleaning
We quote each job individually. This is what makes a difference:
- Any permits to work or inductions
- Whether it’s a one-off visit or part of a schedule
- Whether we need access equipment or extra panels
- The scale of the work
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, call us on 0345 646 2711, or send details by email for straight advice and a fixed quote.
What to send for a quote
To help us quote quickly, please include:
- Problems your staff have spotted
- How we’d reach plant on a roof or in a plant room
- Detail shots of panels, filters and grilles
- Where the site is and what kind of site it is
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before work begins.
About our ventilation duct cleaning in Ayot St Peter
Dust in ventilation ductwork isn’t only a cleanliness issue. It can restrict airflow, make the system work harder and send dust back into occupied rooms. A clean puts the system back as it should be. The work covers toilet extract systems, general extract ductwork and hospitals and care homes, and the jobs we see most are systems missing access panels and ductwork never cleaned since it was installed.
Somewhere as small as Ayot St Peter, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
The report is your system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Between visits
Good habits slow the build-up between visits. Our tips:
- Wipe grilles and diffusers during routine cleaning
- Do not run the ventilation while builders are sanding or cutting
- Watch for water stains around grilles
- Don’t block grilles with furniture or storage
A TR19® certificate and photo report follow every clean. BESA advises keeping certificates in the maintenance log, with the date, location and technician on record.
Do not let construction dust into the ventilation by switching it off or covering the grilles.
Do you need ventilation duct cleaning in Ayot St Peter?
Ductwork is hidden above ceilings and in risers, so dust collects unseen. The grilles get a wipe, but what’s behind them doesn’t.
Common reasons sites call us include:
- Musty smells from the ventilation
- Dirty diffusers dropping dust into rooms
- Rooms that feel airless when the system runs
- Systems missing access panels
School buildings such as Monk's Walk School are typically done in the holidays, so classrooms aren’t disturbed.
What your quote should include
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the quote shows VAT
- Whether the work can be done while the site is closed
- Proof of insurance
What we do, step by step
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a shift or two for a small system, longer for a whole building. Pictures of the system and its access let us plan the work in Ayot St Peter before we set off.
- First the system is surveyed, on site or from photos and drawings.
- Ducts are inspected at access points and the condition recorded.
- Floors and furniture are covered and the ventilation turned off.
- We clean the ductwork, grilles and diffusers through access panels.
- We issue a TR19® certificate and a photo report listing what was cleaned.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Arrange a key holder or contact on site
- Tell us where we can park and unload
Ask for a quote
We do not publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To start, give us a ring on 0345 646 2711 or email us.

Your questions about ventilation duct cleaning in Ayot St Peter
Do you cover smaller places like Ayot St Peter?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.

Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Just give us a ring on 0345 646 2711, or email photos with your opening times and we’ll plan around them.
What about areas you can’t get to?

Do you work with multi-site operators?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
Is TR19 cleaning required by law?
Not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurance policies ask for proof of TR19® cleaning. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005 in England and Wales.
How much does ventilation duct cleaning cost in Ayot St Peter?
We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. We fix the price before we start.
Can you price the work without visiting?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
What does TR19 mean?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
How the job changes from site to site
Hospitals and care homes
Dust control matters during work in occupied care settings. We protect the work area and take everything away.
Offices and retail
Fit-outs in offices and shops leave dust in the ventilation. Cleaning before the new occupants move in makes sense.
