AHU cleaning for kitchens and businesses in Felsted
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. We are often asked to deal with plant that has been serviced but not cleaned and dust built up on fan impellers, across heating and cooling coils, supply and extract fans and dampers and louvres.
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.
Good records are part of the job. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Looking after it afterwards
Simple habits between visits make a real difference. Our advice:
- Change filters on schedule and log each change
- Note any water around the unit or leaks below it
- Diary the inspection date recommended in the report
- Clear leaves and litter away from the intake
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
Managing agents and facilities teams in Felsted
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
In-house cleaning or a specialist?
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
The process
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere as small as Felsted, the date and timings are agreed with you well before the day.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Dig out any earlier paperwork for the system
- Arrange a key holder or contact on site
Ask for a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.

What affects the cost of AHU cleaning
The quote reflects the site in front of us. We take into account:
- The condition we find in the survey
- The size of the system
- Travel, parking and unloading
- Access, including roofs, risers and ceiling voids
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 any work starts, so there are no surprises.
What to send for a quote
You do not need the technical terms. It helps if you can send:
- Wide pictures of the system and the area around it
- When the site is open and when it’s quiet
- Where the site is and what kind of site it is
- How we’d reach plant on a roof or in a plant room
For a fixed quote, call 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You’ll normally have a quote within one working day.

Questions from Felsted
Can you work in Felsted outside opening hours?
Yes, evening, overnight and weekend work is normal for us. It means the site in Felsted keeps running as normal. Tell us your opening hours when you ask for a quote.
Is Felsted within the area you cover?
Yes. Felsted is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you clean the ducts connected to the AHU?
Yes, the ductwork, grilles and diffusers the unit serves. We will tell you after the survey whether the ducts need it.
Will you repair the fan or motor?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report for your maintenance team to follow up.
How much does AHU cleaning cost?
We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before any work starts.
Do you look at the system first?
Yes. We always survey first, either from pictures and details you send or on a site visit. Then you get a fixed quote.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What’s included in an AHU clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
When to call us in Felsted
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
Clients usually contact us when they notice something like this:
- Intake sections clogged with outdoor debris
- Odours coming through the supply air
- Fan sections that haven’t been cleaned in years
- Dirty coils holding back the airflow
Healthcare buildings such as Braintree Community Hospital, about 4.6 miles east, depend on their ventilation; if you manage a surgery, clinic or care home near Felsted, yours matters too.
