What affects the quote in Holly Green
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether it’s a one-off visit or part of a schedule
- How big the system is
- Site requirements such as sign-in and permits
- The number of sites or systems
What you pay depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before any work starts, so you know where you stand.
What we need to know
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any symptoms, from odd noises to smells or leaks
- Your opening hours and when the area is out of use
- The site address and the type of premises
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
AHU cleaning for kitchens and businesses in Holly Green
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. Typical jobs include leaves and litter drawn into the unit and dirty filters cutting the airflow, across heating and cooling coils, dampers and louvres and internal panels.
In a village or hamlet like Holly Green, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

What a clean won’t put right
We will not sell you work that doesn’t address the problem, so these are the things it will not cover:
- Coils that are corroded or leaking and need replacing
- A system that is undersized for the building
- Problems with the unit’s controls or sensors
If you’re not sure, just call us on 0345 646 2711 or drop us a line and we will give you a straight answer before booking.

Aftercare tips
Once we’ve finished, these simple steps help:
- Book the next check in line with the report
- Report musty smells from the vents right away
- Keep inspection doors on the unit in good order
- File each AHU report in the maintenance log
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
Why it’s worth doing now in Holly Green
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. It’s worth booking a check, because nobody sees inside a duct day to day.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before we start.

Your questions about AHU cleaning in Holly Green
Can the work in Holly Green be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. The work in Holly Green can fit around your hours. Let us know the hours you are closed and we’ll book within them.
Can you get to a site in Holly Green?
Yes. Holly Green is within the area we cover across London and the South East. A survey first, from pictures or a visit, means we arrive with the right kit.
How long does an AHU clean take?
The work takes one overnight shift for many single units, with bigger plant phased. Large plant can be split over several shifts, so give us a ring on 0345 646 2711 or use the quote form to talk it through.
How much does AHU cleaning cost in Holly Green?
Every site is different, so each gets its own fixed quote. To get one, call us on 0345 646 2711, or send details by email with the site type, opening hours and a few pictures.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
Are you fully insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
How much notice should we give?
The more notice, the better, especially for out-of-hours work. We typically quote within one working day, and there’s a 24/7 line for emergencies.
Do you give a certificate after the clean?
Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.
In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
What we do, step by step
Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we are 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. If you can send pictures, we can arrive in Holly Green knowing what to expect.
- 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.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Tell us where we can park and unload
- Arrange a key holder or contact on site
