About our AHU cleaning in Nevendon
If the units serving a building in Nevendon have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. The work covers heating and cooling coils, filter sections and drain trays, and people most often call us about dust-coated heating and cooling coils and rooms that smell stuffy when the system runs.
Somewhere as small as Nevendon, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
For insurers and inspectors, the record counts. That is why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What the work involves, part by part
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with pictures so you can decide on any repairs.
Common questions in Nevendon
Can ventilation in schools around Nevendon be cleaned out of term?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 10 schools, colleges and universities with registered kitchens within about a mile and a half of Nevendon. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Do you work overnight in Nevendon?
Yes, out-of-hours work is a big part of what we do. That way a site in Nevendon does not have to lose a day’s trading. When you call us on 0345 646 2711 or send us an email, mention when the site is quiet.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
Can you price the work without visiting?
Normally, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and a fixed quote usually follows within one working day. If photos aren’t enough, we will survey first.
What information do you need?
Where the site is, what it is and when it’s open, plus pictures of the system and your last certificate or report if you have one.
How long does it take to clean an air handling unit?
Typically the clean takes one overnight shift for many single units, with bigger plant phased. We plan the shutdown around that, out of hours if needed.
Can we book visits on a schedule?
Yes, of course. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
What AHU cleaning looks like in Nevendon
Going by the FSA’s register, there are about 10 schools, colleges and universities and about 10 care, childcare and hospital premises serving food across Nevendon and its immediate surroundings (about a mile and a half). Busy, occupied buildings like these are where clean supply air matters most. Basildon University Hospital is the nearest hospital, about 4.1 miles south-west of Nevendon. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. About 28 miles out from central London, Nevendon is part of the South East area we work across. A survey and a fixed quote come first, then the visit at a time that suits you.
Wherever a school like Abacus Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

The process
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. On site, the work takes one overnight shift for many single units, with bigger plant phased. Pictures of the system and its access let us plan the work in Nevendon before we set off.
- The survey covers the unit, its access and how it can be shut down.
- 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.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Tell us where we can park and unload
- Mention any locked doors, roof access or ceiling voids
How to get a quote
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, phone us on 0345 646 2711 or drop us a line.

Fixed quotes for AHU cleaning in Nevendon
The quote reflects the site in front of us. We take into account:
- Whether it’s a one-off visit or part of a schedule
- Whether we need access equipment or extra panels
- Site rules, permits and inductions
- The condition we find in the survey
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.
Helping us quote
When you call or email, these details help:
- How we’d reach plant on a roof or in a plant room
- The times we could work without disrupting the site
- The paperwork from the last visit, if you have it
- Photos showing the whole system and its surroundings
Getting a quote doesn’t take long. Send a few details and pictures, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Store the TR19 paperwork where auditors can find it
- Book the next check in line with the report
- Don’t ignore odours coming through the grilles
- Watch for drips or damp patches near the plant
Restart the unit with your site team or maintenance contractor once we’ve finished. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
Landlords, agents and facilities managers
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.

Signs you need AHU cleaning in Nevendon
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
What we’re most often called out for:
- Dust built up on fan impellers
- Filters that are clogged or overdue
- Odours coming through the supply air
- Blocked condensate drains and slimy trays
Healthcare buildings such as Basildon University Hospital, about 4.1 miles south-west, depend on their ventilation; if you manage a surgery, clinic or care home near Nevendon, yours matters too.
What your quote should include
- When the next visit should be, and why
- Whether the quote shows VAT
- What records you’ll receive afterwards
- Proof of accreditation you can verify
What happens if it’s left?
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. Systems in rural buildings are often out of sight and out of mind.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.
