AHU cleaning in Navestock Side
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. If you have dirty coils holding back the airflow and plant that has been serviced but not cleaned, we can put it right, from dampers and louvres, internal panels and drain trays onwards.
Work in a small place like Navestock Side starts with agreeing access and timings.
For insurers and inspectors, the record counts. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What the work involves, part by part
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
For landlords and multi-site operators
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.

Do you need AHU cleaning in Navestock Side?
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
Most sites get in touch after spotting one of these:
- Rooms that smell stuffy when the system runs
- Air handling units never cleaned inside
- Air handling units due a clean after building work
- Dust built up on fan impellers
Healthcare buildings such as Brentwood Community Hospital, about 3.2 miles south-east, depend on their ventilation; if you manage a surgery, clinic or care home near Navestock Side, yours matters too.

What affects the cost of AHU cleaning
The quote reflects the site in front of us. We take into account:
- Where the site is and how we reach it
- Working hours and out-of-hours timing
- Whether we need access equipment or extra panels
- A single visit or a regular plan
The cost depends on how big the system is, the condition 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.
What to send for a quote
When you contact us, these details help:
- Any previous report or certificate
- Photos showing the whole system and its surroundings
- Any access panels or hatches you can see
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
How the visit works
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes one overnight shift for many single units, with bigger plant phased. Somewhere like Navestock Side, lanes, gates and parking are worth mentioning in advance.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Let us know about parking and loading
- Make sure equipment near the work can be switched off and left to cool
- Arrange a key holder or contact on site
Ask for a quote
Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
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.
What a clean won’t put right
We’ll always give you a straight diagnosis, so here’s what AHU cleaning will not do:
- Leaking heating or cooling coils
- Dirty ducts beyond the unit itself
- Faulty motors, drives or bearings
Not sure which it is? You can phone us on 0345 646 2711 or send us an email and we’ll tell you honestly.

What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.
When should our AHU next be cleaned?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
What does TR19 mean?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
Do you give a certificate after the clean?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
