Fixed quotes for AHU cleaning in Polstead
You will get a fixed price before any work starts. It’s based on:
- The times the site is available
- Whether it’s a one-off visit or part of a schedule
- Access, including roofs, risers and ceiling voids
- The condition of the system
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before we start.
Helping us quote
Photos let us diagnose from a distance. Try to include:
- A few general shots of the system
- The roof, plant room or outside wall the system runs to
- Your last certificate, test record or report
- Where the site is and what kind of site it is
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
How we handle AHU cleaning in Polstead
Our AHU cleans for sites in Polstead cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. The work covers internal panels, dampers and louvres and heating and cooling coils, and common reasons people get in touch are condensate trays that won’t empty and dust built up on fan impellers.
In a village or hamlet like Polstead, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

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. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes from a few hours for a compact unit to a day or more for a large one. In a small place like Polstead, the journey is planned ahead and the visit arranged around the site’s hours.
- We survey the unit from photos or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Agree a time when the area can be out of use
- Tell us about site rules, permits or sign-in
- Make sure equipment near the work can be switched off and left to cool

Is AHU cleaning available in Polstead?

How long does an AHU clean take?

Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.

Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Call us any time and explain what’s happened.
Can you fix a faulty AHU?
Our AHU work is cleaning rather than mechanical repair. Any faults we notice are recorded for your maintenance team to follow up.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
What we are called out for in Polstead
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Any of these means the system needs a check-up:
- Filters that are clogged or overdue
- Units that have only ever had filter changes
- Stale or musty smells from the ventilation
- Dirty coils holding back the airflow
Every job around Polstead ends with a record of what was cleaned and what was found.
Questions to ask before you book
- What hours they’ll be on site
- What records you will receive afterwards
- Which accreditations they hold, and whether you can check them
- If they look at the system before pricing
What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
How the job changes from site to site
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
Aftercare tips
Aftercare is simple, and it makes the next visit easier:
- Don’t ignore odours coming through the grilles
- Don’t store bins or materials near the intake
- Plan the next inspection before the last report gets filed away
- Check the drain tray is emptying during routine visits
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
