Ventilation duct cleaning in Cottered, done properly
Every clean ends with a TR19® certificate and a photo report. The report lists what we cleaned, any sections not reached and a recommended next inspection, giving the ventilation a clean bill of health on paper. We’re often asked to deal with ducts that need a clean before handover and damp or stale smells from grilles, on supply ductwork, general extract ductwork and toilet extract systems.
In a village or hamlet like Cottered, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
The paperwork matters as much as the work. You get a written report with photos after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Leave it or put it right?
A clean system moves air more easily, which takes strain off the fans. Leaving them means the plant works harder for the same result. In a place like Cottered, ductwork and fans are easy to forget until something goes wrong.
You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.

Keeping the system healthy
Aftercare is simple, and it helps at the next visit:
- Book the next inspection on the date the report recommends
- Report dust blowing from grilles right away
- Wipe grilles and diffusers during routine cleaning
- Log every filter change
The report lists the sections we cleaned and any we couldn’t reach, with photos before and after. We will suggest where new access panels would help.
Fit access panels where the ductwork can’t be reached. The worst build-up tends to be where no one can look.
For landlords and multi-site operators
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.

What happens on the day
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. Most of the time goes on the work itself, and that takes a shift or two for a small system, longer for a whole building. Photos of the system and how to reach it help us plan a visit to Cottered.
- First we plan when the work can happen, often out of hours.
- We open the ductwork through its access panels.
- Before pictures are taken and the ducts cleaned section by section.
- Grilles and diffusers are cleaned and refitted.
- We take after pictures and send the certificate and report.
Getting ready for the visit
- Tell us where we can park and unload
- Mention any sign-in, permit or induction we need
- Make sure someone can let us in and lock up afterwards
Ask for a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before any work starts.

What affects the cost of ventilation duct cleaning
The quote reflects the site in front of us. We consider:
- The scale of the work
- Any permits to work or inductions
- What state the system is in
- A single visit or a regular plan
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
What we need to know
Photos let us diagnose from a distance. Try to include:
- A few general shots of the system
- The site address and the type of premises
- The times we could work without disrupting the site
- Where the plant sits or the system leaves the building, such as a roof or outside wall
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.
FAQs for Cottered

Yes, nights and weekends are routine for us. The work in Cottered can fit around your hours. Let us know the hours you are closed and we will book within them.
Who has the legal duty for fire safety?
It depends on the building. 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.
What does TR19 mean?

There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before work begins.
Do we need to close while you work?
Not normally. We need the work area to ourselves while we are on site, so the visit goes in a quiet slot.
Can you price the work without visiting?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote normally follows within one working day. Some sites still need a visit, and we will say so.
