What happens on the day
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before any work starts, and floors and nearby surfaces are sheeted. On site, it takes a single shift for a typical unit, longer for large or heavily soiled ones. A quick note on how to find the site and where to park makes a visit to Sand Hill run smoothly.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
How to prepare
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Find the previous report, if there is one
- Arrange a key holder or contact on site

Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.

AHU cleaning in Sand Hill
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. If you have air handling units with blocked filters and air handling units due a clean after building work, we can put it right.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Think of the report as the system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Report stiff or damaged access doors
- Note any water around the unit or leaks below it
- Keep the area around the fresh air intake clear
- Keep filter changes on time and recorded
Restart the unit with your site team or maintenance contractor once we’ve finished. Check the drain tray is emptying over the first few days to confirm water is draining away.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
Why deal with it now?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. Somewhere as small as Sand Hill, losing a kitchen or building to a fault is felt by everyone who uses it.
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before we start.

Questions from Sand Hill
Can you come to Sand Hill after we close?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Let us know the hours you are closed and we’ll book within them.
Can you get to a site in Sand Hill?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
How much notice do you need?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
Can one contract cover all our sites?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
What about areas you cannot get to?
Anything we cannot reach goes on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
What a clean won’t put right
A few issues sit outside what this work can do:
- Leaking heating or cooling coils
- Problems with the unit’s controls or sensors
- Faulty motors, drives or bearings
Not sure which it is? You can call us on 0345 646 2711 or send us an email and we’ll tell you honestly.

What else we do in Sand Hill
What AHU cleaning looks like in Sand Hill
The FSA’s food hygiene register lists about 3 schools, colleges and universities and about 5 hospitals, care homes and childcare premises with registered kitchens or food service within about 1.5 miles of central Sand Hill. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. At about 40 miles from central London, Sand Hill sits well inside the area we cover. Evening, overnight and weekend visits are all possible. Sand Hill’s nearest hospital, Braintree Community Hospital, is about 4.7 miles south. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Around Sand Hill, as anywhere, ventilation cleaning begins with an inspection. Healthcare ventilation, from large hospitals like Braintree Community Hospital (about 4.7 miles south) to small clinics, depends on clean filters, coils and ducts.
Sand Hill is about 5 miles north-west of Braintree, in Essex. Whether your site is in the middle of Sand Hill or further out, we cover AHU cleaning for every kind of premises, from a single unit to a large public building. Across Essex, we cover 644 places, Sand Hill among them. There’s also a page for Chelmsford, roughly 14 miles from Sand Hill.
AHU cleaning in CM7 follows the same survey, fixed quote and written report as everywhere else we cover. If your site is just outside Sand Hill, we cover Shalford (1 mile south), Church End (1 mile south), Beazley End (2 miles south-east), Almshouse Green (3 miles north-east) and Bocking Churchstreet (4 miles south-east). We also work in nearby towns such as Chelmsford (14 miles south), Braintree (5 miles south-east), Witham (11 miles south-east), Saffron Walden (12 miles north-west), Halstead (6 miles east) and Great Dunmow (8 miles south-west).
Near you in Sand Hill

In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
What the work involves, part by part
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with pictures so you can decide on any repairs.
Filters
Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and the housing around them is cleaned too.
How we price AHU cleaning
The diagnosis comes before the price. The main factors are:
- Site rules, permits and inductions
- A single visit or a regular plan
- The number of sites or systems
- What state the system is in
You won’t find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.
Asking for a quote
We can often survey from photos. The most useful are:
- Close-ups of filters, grilles, hatches or access panels
- The paperwork from the last visit, if you have it
- Photos showing the whole system and its surroundings
- The times we could work without disrupting the site
