AHU cleaning around Rawreth
Going by the FSA’s register, there are about 3 schools, colleges and universities and about 6 care, childcare and hospital premises serving food within 1.5 miles or so of the middle of Rawreth. Busy, occupied buildings like these are where clean supply air matters most. About 5.1 miles south-east of Rawreth is Chartwell Private Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. Rawreth, about 30 miles from central London, is within our usual area. Visits are booked around your hours, evenings and weekends included.
Hospitals such as Chartwell Private Hospital (about 5.1 miles south-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Rawreth are no different. Classrooms and halls at schools such as Our Lady of Ransom Catholic Primary School are easiest to work in when pupils are away.

AHU cleaning in Rawreth
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after pictures in a report. The work covers internal panels, heating and cooling coils and filter sections, and the jobs we see most are stale or musty smells from the ventilation and air handling units never cleaned inside.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

How the job changes from site to site
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.
Drain trays
Older trays can corrode and start leaking. We record their condition with photos so you can decide on any repairs.

FAQs for Rawreth
Can the work in Rawreth be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Can a school’s ventilation in Rawreth be done out of term time?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 3 schools, colleges and universities with registered kitchens within about a mile and a half of Rawreth. Tell us your holiday dates and we will book the visit for when the site is empty.
Is Rawreth in your area?
Yes. Rawreth is part of the area we cover, as part of our area across London and the South East.
Do you give a certificate after the clean?
Yes, both a certificate and a report with photos. It includes a recommended date for the next check.
Do you look at the system first?
Yes. Photos often do the job, and larger or hidden systems get a visit.
What information do you need?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
How far ahead should we book?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
Aftercare tips
After the visit, a few habits help the work last:
- Change filters on schedule and log each change
- Report stiff or damaged access doors
- Do not store bins or materials near the intake
- Report water on the plant room floor
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.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
Multi-site and managed buildings
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Facilities teams in offices, schools and healthcare sites book us too across Essex. Larger estates can be phased building by building to keep disruption down.

How the visit works
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes anything from half a day for one small unit to several shifts for a plant room full of them. A few photos of the system help us make the most of a visit to a place like Rawreth.
- We survey the unit from pictures 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.
- We close up the unit and send the certificate and before and after photos.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Plan for cooking equipment or plant to be off before we arrive
- Arrange a key holder or contact on site
How to get a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
Advice
Leave it or put it right?
Stuffy rooms and stale smells in a building in Rawreth can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. Out of sight is the usual reason a rural system goes too long without attention.
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 make a difference.
Why book with us
- In business since 2009
- One contact for all your sites in London and the South East

- A written report with pictures after every visit
When it’s something else
We’ll always give you a straight diagnosis, so here’s what this work can’t put right:
- Mechanical faults with motors, belts or bearings
- Building management system faults
- Dirty ducts beyond the unit itself
If you are not sure, just ring 0345 646 2711 or send us an email and we will give you a straight answer.
