How we price AHU cleaning
The price is fixed before any work begins. It’s based on:
- How many systems or sites are involved
- The scale of the work
- Site requirements such as sign-in and permits
- What state the system is in
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before any work starts.
What to send for a quote
You don’t need the technical terms. It helps if you can send:
- Close-ups of filters, grilles, hatches or access panels
- Photos showing the whole system and its surroundings
- How we’d reach plant on a roof or in a plant room
- Your last certificate, test record or report
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before any work starts.
AHU cleaning in Roxbourne
Our AHU cleaning covers sites in Roxbourne and the rest of Greater London, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. We’re often asked to deal with rooms that smell stuffy when the system runs and air handling units never cleaned inside, across filter sections, heating and cooling coils and drain trays.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. In Roxbourne, as elsewhere, cleaning starts with an inspection of what’s there.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
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.
Different parts, different methods
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
Common questions in Roxbourne
Do you do school ventilation cleaning in Roxbourne in the summer holidays?
Yes, out-of-term visits are normal for schools. With about 21 schools and colleges on the FSA’s register within roughly a mile and a half of Roxbourne, it pays to plan holiday dates ahead. You can give us a ring on 0345 646 2711, or email photos with the dates the site is empty.
Can you come to Roxbourne after we close?
Yes, nights and weekends are routine for us. It means the site in Roxbourne keeps running as normal. Just call us on 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
Is a quote from pictures possible?
Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
How much does AHU cleaning cost?
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. You get a fixed price before we start.
What do you need from me for a quote?
Some pictures and a quick description of the system plus the address and your hours. If we need more, we will ask.
How often do AHUs need cleaning?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and we will suggest an interval after the first clean.
What do you do to protect the area?
By covering it before any work starts. We keep the work contained and leave the area clean.
Why it’s worth doing now in Roxbourne
If people in a building in Roxbourne complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before we start.
Why Roxbourne businesses choose us
- Out-of-hours work and a 24/7 emergency line
- CHAS and SafeContractor accredited, with ISO 9001

- A written report with pictures after every visit

Signs you need AHU cleaning in Roxbourne
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
Most sites get in touch after spotting something like this:
- Air handling units with blocked filters
- Leaves and litter drawn into the unit
- Units needing a clean before a new tenant or handover
- Dirty coils holding back the airflow
If you manage a school such as The Moriah Jewish Day School, ventilation cleaning is best booked for the holidays.
Questions to ask before booking
- Whether VAT is included
- Whether the quote is based on a survey or pictures
- What records you’ll receive afterwards
- What insurance they carry
Multi-site and managed buildings
When the building owner and the occupier are different, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
How it works
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, and the sign-off is a written report with pictures. Most of the time goes on the work itself, which takes half a day to a full day per unit, with large plant planned over several shifts. Most London sites can’t stop for the day, so work in Roxbourne is usually done overnight, early in the morning or at weekends.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Tell us where we can park and unload
- Make sure equipment near the work can be switched off and left to cool
- Find the previous report, if there is one
