Do you need AHU cleaning in Stanford Rivers?
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and the finer material travels on.
Any of these means the system needs a check-up:
- Stale or musty smells from the ventilation
- Dust built up on fan impellers
- Units needing a clean before a new tenant or handover
- Drain trays holding standing water
If you run a surgery, dental practice or care home near Stanford Rivers, clean ventilation matters as much to you as to a hospital like St. Margaret's Hospital (about 4.2 miles west).

AHU cleaning for kitchens and businesses in Stanford Rivers
We clean the parts of the unit where dirt and moisture gather: 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. We are often asked to deal with units needing a clean before a new tenant or handover and filters that are clogged or overdue, on supply and extract fans, heating and cooling coils and filter sections.
Work in a small place like Stanford Rivers starts with agreeing access and timings.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

- Mechanical faults with motors, belts or bearings

Questions from Stanford Rivers
Do you work at weekends in Stanford Rivers?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Let us know the hours you are closed and we will book within them.
Do you cover Stanford Rivers for AHU cleaning?
Yes. We work across London and the South East, and Stanford Rivers is part of that. Just phone us on 0345 646 2711 or send us an email with a few details of the site.
What information do you need?
Some pictures and a quick description of the system, with the address and opening hours. We will ask for anything else we need.
Can you quote from pictures?
Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
What do you do to protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
How often do AHUs need cleaning?
That is set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Where does the waste go?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
How the visit works
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 anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere like Stanford Rivers, lanes, gates and parking are worth mentioning in advance.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Let us know about permits to work or site inductions
- Let us know about parking and loading

Advice
What affects the cost of AHU cleaning
A fixed price needs a few facts first. We check:
- Parking and loading at the site
- The times the site is available
- Any permits to work or inductions
- Whether it’s a one-off visit or part of a schedule
The cost depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.
Helping us quote
Before you ask for a quote, gather:
- Photos showing the whole system and its surroundings
- How we’d reach plant on a roof or in a plant room
- The postcode and the type of business
- The paperwork from the last visit, if you have it
Getting a quote doesn’t take long. Call or email with a few details and you will usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Keeping the system healthy
Aftercare is simple, and it makes the next visit easier:
- Keep the certificate and photo report with the plant records
- Diary the inspection date recommended in the report
- Make sure condensate is draining away
- Watch for drips or damp patches near the plant
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.

Multi-site and managed buildings
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 are happy to quote for all of it.
We regularly work with managing agents. Send the address, what’s needed and how access works, and we will send a fixed quote.
In-house cleaning or a specialist?
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. Leave those to us.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
