AHU cleaning in Fernhurst, done properly
Our AHU cleaning covers sites in Fernhurst and the rest of Surrey, 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 are often asked to deal with leaves and litter drawn into the unit and units that have only ever had filter changes, on filter sections, supply and extract fans and drain trays.
In a village or hamlet like Fernhurst, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Questions from Fernhurst
Can the work in Fernhurst be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. It means the site in Fernhurst keeps running as normal. Tell us your opening hours when you ask for a quote.
Do you cover smaller places like Fernhurst?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Can you price the work without visiting?
Yes, where the photos show enough. If not, a site survey comes first, then a fixed quote.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
What information do you need?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
Where does the waste go?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Signs you need AHU cleaning in Fernhurst
No filter stops everything. 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:
- Fan sections that haven’t been cleaned in years
- Dust-coated heating and cooling coils
- Blocked condensate drains and slimy trays
- Filters that are clogged or overdue
Healthcare buildings such as Haslemere and District Hospital, about 2.9 miles north, depend on their ventilation; if you manage a surgery, clinic or care home near Fernhurst, yours matters too.
What to look for in a quote

When it’s something else
To be straight with you, some problems need a different fix:
- Airflow problems caused by the system’s design
- Building management system faults
- The supply and extract ducts, quoted separately
Not sure which it is? You can call 0345 646 2711 or send us an email and we will tell you honestly.

Fernhurst buildings and their air
Food Standards Agency records list about 3 schools, colleges and universities registered as food businesses in and around Fernhurst, up to about a mile and a half out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. About 2.9 miles north of Fernhurst is Haslemere and District Hospital, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. About 41 miles out from central London, Fernhurst is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site.
For schools like Fernhurst Primary School, the holidays are the usual time to inspect and clean ventilation.

How the job changes from site to site
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
Why act early in Fernhurst
Stuffy rooms and stale smells in a building in Fernhurst can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. Somewhere as small as Fernhurst, losing a kitchen or building to a fault is felt by everyone who uses it.
What you pay reflects the actual work. That’s why every job is surveyed first, and the price is agreed before work begins.
Why Fernhurst businesses choose us
- Fixed quotes, typically within one working day
- Each visit written up, with pictures
- Trading since 2009
- One number for every site across the South East and London
See our cost guide or our accreditations.
Between visits
Simple habits between visits make a real difference. We recommend:
- Do not ignore odours coming through the grilles
- Report stiff or damaged access doors
- Plan the next inspection before the last report gets filed away
- Keep the certificate and photo report with the plant records
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
What happens on the day
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. A few pictures of the system help us make the most of a visit to a place like Fernhurst.
- 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.
- 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 the best time to work, such as after service or at a weekend
- Let us know about permits to work or site inductions
- Move anything stored near the system
How to get a quote
We do not publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, phone us on 0345 646 2711 or use the quote form.

Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
