What we’re called out for in Offington
Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.
These are the problems we see most often:
- Air handling units never cleaned inside
- Dirty coils holding back the airflow
- Units needing a clean before a new tenant or handover
- Odours coming through the supply air
Healthcare ventilation, from large hospitals like Worthing Hospital (about 1.6 miles south-east) to small clinics, depends on clean filters, coils and ducts.
What your quote should include
- What records you will receive afterwards
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- If they look at the system before pricing
- Whether inaccessible sections are listed on the report
AHU cleaning in Offington, done properly
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with photos, so the report shows exactly what was done. Common call-outs are for dust built up on fan impellers and odours coming through the supply air, on supply and extract fans, drain trays and filter sections.
In a village or hamlet like Offington, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
The sign-off is always in writing: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Fixed quotes for AHU cleaning in Offington
The price is fixed before any work begins. It’s based on:
- How many systems or sites are involved
- Where the site is and how we reach it
- Whether we need access equipment or extra panels
- What state the system is in
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before we start.
What we need to know
Photos let us diagnose from a distance. Try to include:
- Wide photos of the system and the area around it
- Your opening hours and when the area is out of use
- The paperwork from the last visit, if you have it
- The postcode and the type of business
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before any work starts.
The process
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes from a few hours for a compact unit to a day or more for a large one, and the area is cleaned down before we leave. A quick note on how to find the site and where to park makes a visit to Offington run smoothly.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Mention any parking or loading restrictions
- Let us know when the site is closed or quiet
Ask for a quote
For a fixed quote, call us on 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.

Keeping the system healthy
A little care between visits keeps the system in better shape. Our advice:
- Make sure condensate is draining away
- Keep inspection doors on the unit in good order
- Stick to the filter change plan
- Flag stale or damp smells in the supply air
Stick to the filter change schedule, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
Why deal with it now?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. Our emergency line runs 24/7, but a planned visit to Offington is calmer for everyone.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
What you get with us
- A fixed price before any work starts
- Every visit written up, with pictures
- One number for every site across the South East and London
- CHAS and SafeContractor accredited, with ISO 9001
How the job changes from site to site
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins aren’t damaged.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
