How we price AHU cleaning
The price is fixed before any work begins. It’s based on:
- Whether we need access equipment or extra panels
- A single visit or a regular plan
- Parking and loading at the site
- Site rules, permits and inductions
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
What to send for a quote
To speed up the quote, please include:
- The paperwork from the last visit, if you have it
- Where the site is and what kind of site it is
- Problems your staff have spotted
- When the site is open and when it’s quiet
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. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
About our AHU cleaning in Finmere
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so the report shows exactly what was done. If you’re dealing with stale or musty smells from the ventilation and units that have only ever had filter changes, we can help, from filter sections, heating and cooling coils and dampers and louvres onwards.
For a building in or near Finmere, 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.
Duct Doctor has 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.

Landlords, agents and facilities managers
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
Common problems we fix in Finmere
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that’s the air they breathe for hours on end.
Keep an eye out for these warning signs:
- Fan sections that haven’t been cleaned in years
- Plant that has been serviced but not cleaned
- Intake sections clogged with outdoor debris
- Filters that are clogged or overdue
Wherever a school like Finmere Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Questions to ask before booking
- Whether a written report and photos are included
- If they look at the system before pricing
- What happens if part of the system cannot be accessed
- Which accreditations they hold, and whether you can check them

FAQs for Finmere
Can you get to a site in Finmere?
Yes. Villages and rural sites across the South East are part of our work, Finmere included. Let us know about access, parking and anything unusual about getting there when you book.
Do you work overnight in Finmere?
Yes, nights and weekends are routine for us. It means the site in Finmere keeps running as normal. When you call us on 0345 646 2711 or use the quote form, mention when the site is quiet.
How long does an AHU clean take?
As a guide, it takes anything from half a day for one small unit to several shifts for a plant room full of them. We plan the shutdown around that, including evenings or weekends.
What types of premises do you cover?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
Can you quote from pictures?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we typically come back within one working day. Some sites still need a visit, and we’ll say so.
Do you work with multi-site operators?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
How much does AHU cleaning cost?
We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before any work starts.
How do you protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
What happens on the day
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’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a single shift for a typical unit, longer for large or heavily soiled ones. For a village or hamlet like Finmere, tell us about narrow lanes, gates and parking when you book.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after pictures.
Getting ready for the visit
- Mention any sign-in, permit or induction we need
- Move anything stored near the system
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Ask for a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Aftercare tips
Think of this as the after-treatment advice, in brief:
- File each AHU report in the maintenance log
- Make sure the unit’s access doors open easily
- Report water on the plant room floor
- Don’t store bins or materials near the intake
Stick to the filter change schedule, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
Staff cleaning versus specialist work
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Why act early in Finmere
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. With notice, the visit to Finmere can be fitted around your bookings and events.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.
