Do you need AHU cleaning in Danehill?
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, a little more each month.
Most sites get in touch after spotting one of these:
- Units needing a clean before a new tenant or handover
- Odours coming through the supply air
- Coils clogged with dust and debris
- Dirty fans and fan housings
For schools like Danehill Church of England Primary School, the holidays are the usual time to inspect and clean ventilation.
Questions to ask before booking
- How VAT is shown on the quote
- Whether they’re fully insured
- How areas they cannot reach will be recorded
- What records you’ll receive afterwards
About our AHU cleaning in Danehill
If the units serving a building in Danehill have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. If you’re dealing with condensate trays that won’t empty and air handling units never cleaned inside, we can help, from supply and extract fans, drain trays and dampers and louvres onwards.
For a building in or near Danehill, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
A written report with pictures follows every visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Questions from Danehill
Do you work at weekends in Danehill?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Just ring 0345 646 2711 or use the quote form with your opening times and we will plan around them.
Do you offer AHU cleaning in Danehill?
Yes, Danehill is covered. A fixed quote normally follows within one working day of the survey details.
Will we get paperwork for the AHU clean?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
Can you fix a faulty AHU?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report so your maintenance contractor can deal with it.
Do you clean the ductwork as well?
Yes. We reach the ducts through access panels, and any sections we can’t reach are noted in the report, and new panels can be fitted.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Will the ventilation be off while you clean?
Yes. We cannot clean a running unit, so it’s switched off and made safe first. The shutdown is planned with whoever runs the building.
What information do you need?
Where the site is, what it is and when it’s open, along with a few photos and any previous report.
Managing agents and facilities teams in Danehill
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
What happens if it’s left?
Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Somewhere as small as Danehill, losing a kitchen or building to a fault is felt by everyone who uses it.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before work begins.
What you get with us
- Fully insured
- One contact for all your sites in London and the South East
- Every job surveyed first
- Every visit written up, with photos

What affects the quote in Danehill
The quote reflects the site in front of us. We take into account:
- Access, including roofs, risers and ceiling voids
- How many systems or sites are involved
- How big the system is
- Parking and loading at the site
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.
What to send for a quote
To speed up the quote, send us:
- Where the site is and what kind of site it is
- Detail shots of panels, filters and grilles
- A few general shots of the system
- When the site is open and when it’s quiet
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
The process
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes one overnight shift for many single units, with bigger plant phased. Somewhere like Danehill, lanes, gates and parking are worth mentioning in advance.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Move anything stored near the system
- Tell us the best time to work, such as after service or at a weekend
- Plan for cooking equipment or plant to be off before we arrive
