AHU cleaning in Britwell
If the units serving a building in Britwell have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. If you have blocked condensate drains and slimy trays and debris and leaves in the fresh air intake, we can help, from supply and extract fans, internal panels and filter sections onwards.
Around a place like Britwell, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Even a small system collects dust in its ducts and filters.
The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

What we do, step by step
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes one overnight shift for many single units, with bigger plant phased. In a smaller place like Britwell, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Have your last certificate or report to hand
- Mention any locked doors, roof access or ceiling voids
- Make sure someone can let us in and lock up afterwards
How to get a quote
We do not publish a price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To get going, phone us on 0345 646 2711, or email photos.
Advice
How we price AHU cleaning
The survey tells us what the work involves. The main factors are:
- The size of the system
- Travel, parking and unloading
- Any permits to work or inductions
- Whether we need access equipment or extra panels
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before any work starts, so you know where you stand.
What we need to know
Many jobs can be priced from pictures and some basics. Useful things to send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The postcode and the type of business
- The paperwork from the last visit, if you have it
- Close-ups of filters, grilles, hatches or access panels
Quotes are quick. Call or email with a few details and you’ll usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
In-house cleaning or a specialist?
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Your questions about AHU cleaning in Britwell
Do you work overnight in Britwell?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.
Is Britwell within the area you cover?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Where does the waste go?
We take it away when we go. During the work, it’s contained to keep the area clean.
What’s included in an AHU clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
How much does AHU cleaning cost in Britwell?
Size, condition, access and working hours all affect the cost. Call for a fixed quote, normally ready within one working day.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. Before we leave, we tidy up and clean down.
Do you have a 24/7 line?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Can you clean the ducts connected to the AHU?
Yes. Ductwork is cleaned through access panels, and any sections we can’t reach are noted in the report, with new panels fitted where necessary.
Part by part
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards before the unit is handed back.
Why act early in Britwell
A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. It also means the next inspection has less to find. You choose the date of a planned visit, and a breakdown never asks.
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before we start.
Why book with us
- A single point of contact for sites across the South East and London
- Each visit written up, with pictures
- Full insurance on every job
- CHAS and SafeContractor accredited, with ISO 9001
Aftercare tips
So the system stays in good health:
- Stick to the filter change plan
- Note any water around the unit or leaks below it
- Keep the area around the fresh air intake clear
- Check the drain tray is emptying during routine visits
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
