About our AHU cleaning in Batchworth Heath
Our AHU cleans for sites in Batchworth Heath cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after photos in a report. If you are dealing with dirty coils holding back the airflow and condensate trays that won’t empty, we can help.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

How it works
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes one overnight shift for many single units, with bigger plant phased, and the area is cleaned down before we leave. Pictures of the system and its access let us plan the work in Batchworth Heath before we set off.
- We survey the unit from photos or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Before we arrive
- Mention any parking or loading restrictions
- Clear loose items from the work area
- Let us know when the site is closed or quiet
Getting a quote
Getting a quote doesn’t take long. Call or email with a few details and you’ll typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

What affects the cost of AHU cleaning
Every site gets its own quote. These are the things that affect it:
- Working hours and out-of-hours timing
- The condition of the system
- Travel, parking and unloading
- Whether several sites go on one quote
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Asking for a quote
You do not need the technical terms. It helps if you can send:
- The roof, plant room or outside wall the system runs to
- The paperwork from the last visit, if you have it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Detail shots of panels, filters and grilles
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 we start.
What we’re called out for in Batchworth Heath
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:
- Plant that has been serviced but not cleaned
- Blocked condensate drains and slimy trays
- Debris and leaves in the fresh air intake
- Air handling units with blocked filters
Hospitals such as Mount Vernon Hospital (about within half a mile south) show how much a building can rely on clean ventilation, and smaller healthcare sites near Batchworth Heath are no different.

FAQs for Batchworth Heath
Do you cover smaller places like Batchworth Heath?
Yes, we work in villages as well as towns, and Batchworth Heath is covered. The journey is planned ahead, so a few details about the route help.
Do you do school ventilation cleaning in Batchworth Heath in the summer holidays?
Yes. The holidays are the usual time for school work. With about 14 schools and colleges on the FSA’s register within roughly a mile and a half of Batchworth Heath, it pays to plan holiday dates ahead. Send us your term dates when you give us a ring on 0345 646 2711 or send us an email, and we’ll fit the work in.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
What accreditations do you have?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
Do you look at the system first?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Do you repair air handling units?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report so your maintenance contractor can deal with it.
Can you come out in an emergency?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
Can you clean without disrupting the building?
Yes. We time the work to fit the building’s hours. Healthcare and care settings are planned with staff.
Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
How the job changes from site to site
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.
What happens if it’s left?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, ready to show anyone who asks. It’s worth booking a check, because nobody sees inside a duct day to day.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will go through it with you.
