AHU cleaning for kitchens and businesses in Standford
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. The work covers filter sections, internal panels and drain trays, and common reasons people get in touch are intake sections clogged with outdoor debris and condensate trays that won’t empty.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
A written report with photos follows each visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Why it’s worth doing now in Standford
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. Equipment tucked in a roof space or outbuilding near Standford rarely gets looked at unless someone books it.
We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.
Why book with us
- Survey first, then a fixed quote
- One contact for all your sites in London and the South East
- A written report with pictures after each visit
- Ventilation hygiene specialists since 2009
What affects the cost of AHU cleaning
You’ll get a fixed price before we start. It takes into account:
- Access, including roofs, risers and ceiling voids
- How many systems or sites are involved
- Travel, parking and unloading
- The size of the system
What you pay depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before we start, so you know where you stand.
Helping us quote
We can often survey from photos. Try to include:
- Any symptoms, from odd noises to smells or leaks
- Your opening hours and when the area is out of use
- Any previous report or certificate
- Close-ups of filters, grilles, hatches or access panels
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before any work starts.
What a clean will not put right
To be straight with you, some problems need a different fix:
- Breakdowns that need a mechanical engineer
- Leaking heating or cooling coils
- Problems with the unit’s controls or sensors
Not sure which it is? You can call us on 0345 646 2711 or send us an email and we’ll tell you honestly before booking.
Where we work
- Internal panels
- Drain trays
- Dampers and louvres
- Filter sections
- Heating and cooling coils
- Supply and extract fans
For landlords and multi-site operators
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 can quote for the whole system.
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
The process
At the end of the visit, someone from your team can look over the work with us. 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 a single shift for a typical unit, longer for large or heavily soiled ones. Seeing the system in photos first means the trip to Standford can be planned properly.
- 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.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Dig out any earlier paperwork for the system
- Arrange a key holder or contact on site
- Let us know how we reach the system, including roofs, risers and plant rooms

Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
Advice
Questions from Standford
Can the work in Standford be done at night or at weekends?
Yes, nights and weekends are routine for us. That way a site in Standford doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Do you do school ventilation cleaning in Standford in the summer holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 3 schools, colleges and universities with registered kitchens within about a mile and a half of Standford. Just call 0345 646 2711, or email photos with your term dates and we will plan around them.
What about areas you cannot get to?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
How much notice do you need?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Which accreditations do you hold?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
What do you do to protect the area?
By covering it before any work starts. We keep the work contained and leave the area clean.
Do you give a certificate after the clean?
Yes, both a certificate and a report with photos. The report also suggests when the unit should next be inspected.

What we’re called out for in Standford
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and slime and smells soon follow.
Keep an eye out for any of the following:
- Dirty coils holding back the airflow
- Blocked condensate drains and slimy trays
- Fan sections that haven’t been cleaned in years
- Rooms that smell stuffy when the system runs
Classrooms and halls at schools such as Weyford Nursery and Primary School are easiest to work in when pupils are away.
Questions to ask before you book
- Proof of insurance
- Proof of accreditation you can verify
- If the quote is a fixed price or an estimate
- Whether inaccessible sections are listed on the report
What else we do in Standford
Keeping the system healthy
After the visit, a few habits help the work last:
- Make sure condensate is draining away
- Keep filter changes on time and recorded
- Do not ignore odours coming through the grilles
- File each AHU report in the maintenance log
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
