What the work involves, part by part
Grilles and diffusers
Grilles and diffusers are where the ducts meet the room. We clean them as part of the job, so dust on them is not blown back in.
Offices and retail
Offices and shops tend to need the work done outside opening hours to keep the space open.
Ventilation duct cleaning for kitchens and businesses in Aspenden
Ductwork is reached through access panels at intervals along the system. Where there aren’t enough panels to reach every section, we note the uncleaned parts in the report, and we can fit new panels so they’re covered next time. The work covers offices and schools, supply ductwork and toilet extract systems, and the jobs we see most are odours carried round the building by the ducts and ventilation that needs a TR19® Air inspection.
In a village or hamlet like Aspenden, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

How we price ventilation duct cleaning
There’s no set price list, because no two systems are the same. What we look at:
- A single visit or a regular plan
- Site rules, permits and inductions
- The scale of the work
- Travel, parking and unloading
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before any work starts.
What we need to know
There’s no need for technical detail. It helps if you can send:
- Problems your staff have spotted
- The site address and the type of premises
- Close-ups of filters, grilles, hatches or access panels
- Your last certificate, test record or report
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.
Honest limits
A few issues sit outside what this work can do:
- Grease in kitchen extract systems, cleaned to TR19® Grease instead
- Problems with how the system is controlled
- Ducts that are damaged, corroded or leaking and need replacing
If you’re not sure, just call 0345 646 2711, or email photos and we’ll give you a straight answer.

What staff can safely do
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Why it’s worth doing now in Aspenden
Smells, dust around grilles and stuffy rooms are signs the system needs attention. Acting early keeps the clean simpler. Equipment tucked in a roof space or outbuilding near Aspenden rarely gets looked at unless someone books it.
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and the price is agreed before we start.

Aspenden questions
Do you do school ventilation cleaning in Aspenden in the summer holidays?
Yes, holiday work suits schools best. Around Aspenden, the Food Standards Agency lists about 5 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
Can you come to Aspenden after we close?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Just call us on 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
Do you provide a report?
Yes. You get a TR19® certificate and a report with before and after pictures. Keep them in the maintenance log.
Who is the responsible person?
In the words of the Fire Safety Order 2005, it’s the responsible person. It’s normally the employer, or whoever controls the building, and where several people have control, each can have duties. Your lease and fire risk assessment should make it clear.
Will you clean the vents in the rooms?
Yes. Where they can be removed, they’re taken down, cleaned and refitted. Fixed ones are cleaned in place.
How do you protect the area?
Floors and surfaces near the work are sheeted before work begins, and anything we remove is contained. Before we leave, we tidy up and clean down.
Do you survey before quoting?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where needed. Then you get a fixed quote.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Looking after it afterwards
A little care between visits keeps the system in better shape. We recommend:
- Keep to the inspection interval in your report
- Switch the ventilation off or cover grilles during dusty building work
- Report dust blowing from grilles straight away
- Make sure nothing is stacked against extract grilles
Pass the paperwork to your facilities or maintenance team, so the history stays together. Over time, it shows how quickly the system gets dirty.
Make sure there are enough access panels to inspect and clean the ducts. Hidden sections are the ones that get worst.

What we do, step by step
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. 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 weekend for a modest system, with large buildings phased floor by floor. Pictures of the system and its access let us plan the work in Aspenden before we set off.
- We agree timings that suit the building, including evenings and weekends.
- We open the ductwork through its access panels.
- Before pictures are taken and the ducts cleaned section by section.
- We clean the grilles and diffusers and put them back.
- We take after photos and send the certificate and report.
Preparing for the visit
- Find the previous report, if there is one
- Clear loose items from the work area
