AHU cleaning for kitchens and businesses in Stanton St John
Our AHU cleans for sites in Stanton St John cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after photos in a report. The work covers dampers and louvres, heating and cooling coils and internal panels, and people most often call us about dirty filters cutting the airflow and dust built up on fan impellers.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

How we price AHU cleaning
The survey tells us what the work involves. The main factors are:
- The condition we find in the survey
- A single visit or a regular plan
- Whether several sites go on one quote
- Travel, parking and unloading
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. The price is fixed before we start.
What we need to know
When you contact us, these details help:
- Any access panels or hatches you can see
- The times we could work without disrupting the site
- Your last certificate, test record or report
- Wide pictures of the system and the area around it
We do not publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To get going, call 0345 646 2711, or email photos.
What we do, step by step
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before work begins, and the area around the work is covered and protected. On site, it takes anything from half a day for one small unit to several shifts for a plant room full of them. Pictures of the system and its access let us plan the work in Stanton St John before we set off.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after photos.
Getting ready for the visit
- Mention any locked doors, roof access or ceiling voids
- Tell us about site rules, permits or sign-in
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.
Advice
Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
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, next to our reports.

What we are called out for in Stanton St John
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that’s the air they breathe for hours on end.
Signs it’s time to call us include:
- Rooms that smell stuffy when the system runs
- Debris and leaves in the fresh air intake
- Units that have only ever had filter changes
- Air handling units due a clean after building work
Wherever a school like Wheatley Park School has ducted ventilation, a half-term visit keeps the work out of lesson time.
What to look for in a quote
- What paperwork you get at the end
- When they can work, and whether that is outside your opening hours
- Proof of accreditation you can verify
- What’s included in the scope, part by part
When something else is needed
We’d rather tell you now than book work that will not help, so these are the things it will not cover:
- Breakdowns that need a mechanical engineer
- A system that is undersized for the building
- Leaking heating or cooling coils
Not sure which it is? You can ring 0345 646 2711 or email us and we will tell you honestly before you book.
Parts of the system we cover
- Drain trays
- Supply and extract fans
- Dampers and louvres
- Internal panels
- Heating and cooling coils
- Filter sections
Leave it or put it right?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. It’s worth booking a check, because nobody sees inside a duct day to day.
The cost depends on the size of the system, what state it’s in and access to every part of it. We give you a fixed price before we start, so there are no surprises.
What you get with us
- A fixed price before any work starts
- Every visit written up, with pictures
- Out-of-hours work and a 24/7 emergency line
- We diagnose before we treat

Multi-site and managed buildings
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
Stanton St John questions
Do you cover smaller places like Stanton St John?
Yes, we work in villages as well as towns, and Stanton St John is covered. Photos of the system and directions to the site help us plan the visit.
Do you work overnight in Stanton St John?
Yes, nights and weekends are routine for us. That way a site in Stanton St John doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, plus pictures of the system and your last certificate or report if you have one.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and we will quote them together.
Do you need to switch the unit off?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
Can you price the work without visiting?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
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. Work is timed around how each site runs.
