Kelvedon Hatch AHU cleaning
We cover Kelvedon Hatch for cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces. Fixed quotes, work around your opening hours and photo reports on every job.

AHU cleaning for kitchens and businesses in Kelvedon Hatch
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. Common call-outs are for debris and leaves in the fresh air intake and air handling units with blocked filters, on heating and cooling coils, internal panels and dampers and louvres.
Work in a small place like Kelvedon Hatch starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Each visit ends with a written report and pictures, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Between visits
Once we’ve finished, these simple steps help:
- Check the drain tray is emptying during routine visits
- Book the next check in line with the report
- Watch for drips or damp patches near the plant
- Report stiff or damaged access doors
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
Managing agents and facilities teams in Kelvedon Hatch
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.

What happens if it’s left?
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. If the system at a site near Kelvedon Hatch fails, there may be nowhere nearby to move to.
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before any work starts.

Busy, occupied buildings like these are where clean supply air matters most. Brentwood Community Hospital is the nearest hospital, about 3.3 miles south-east of Kelvedon Hatch. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. Kelvedon Hatch, about 20 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours.

Staff cleaning versus specialist work
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, and that is where we come in.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
How it works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes anything from half a day for one small unit to several shifts for a plant room full of them. Rural roads and tight entrances are worth telling us about before a visit to Kelvedon Hatch.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Clear the space around the work
- Let us know when the site is closed or quiet
- Let us know about permits to work or site inductions
Ask for a quote
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, the quote is fixed before any work is booked.
Related advice
Kelvedon Hatch: your questions answered
Do you do school ventilation cleaning in Kelvedon Hatch in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Kelvedon Hatch. You can give us a ring on 0345 646 2711, or send details by email with the dates the site is empty.
Will you come out to Kelvedon Hatch?
Yes. Villages and rural sites across the South East are part of our work, Kelvedon Hatch included. Let us know about access, parking and anything unusual about getting there when you book.
Do you work evenings or weekends?
Yes, wherever it helps the building. We plan the shutdown window with you.
What about areas you can’t get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What happens to the waste?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’ve been trading since 2009 and we’re fully insured.
Do you need to switch the unit off?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
Do you need AHU cleaning in Kelvedon Hatch?
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
These are the problems we see most often:
- Condensate trays that won’t empty
- Dirty filters cutting the airflow
- Units needing a clean before a new tenant or handover
- Rooms that smell stuffy when the system runs
If you manage a school such as Kelvedon Hatch Community Primary School, ventilation cleaning is best booked for the holidays.
What to look for in a quote
- Proof of insurance
- How areas they can’t reach will be recorded
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the figure could change on the day
What a clean will not put right
In fairness, there are a few things this work won’t fix:
- Mechanical faults with motors, belts or bearings
- Controls and BMS settings that run the unit
- A system that’s undersized for the building
If you are not sure, just phone us on 0345 646 2711 or email us and we’ll give you a straight answer.
