How we handle AHU cleaning in Leigh-on-Sea
Our AHU cleans for sites in Leigh-on-Sea cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. The work covers supply and extract fans, internal panels and heating and cooling coils, and the jobs we see most are drain trays holding standing water and dust-coated heating and cooling coils.
For a building near Leigh-on-Sea, the visit is planned around how it’s used, and the journey is planned ahead. The work is the same as in any town: inspect, clean, record.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Leave it or put it right?
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. That makes the next inspection of a building in Leigh-on-Sea simpler. A visit arranged in advance is far less disruptive than a callout on a busy day.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before work begins.
Why us?
- We diagnose before we treat
- Fixed quotes from a survey or pictures
- Fully insured
- Work around your opening hours, with 24/7 emergency cover
Looking after it afterwards
After the visit, a few habits help the work last:
- Keep the area around the fresh air intake clear
- Keep the certificate and photo report with the plant records
- Watch for drips or damp patches near the plant
- Do not ignore odours coming through the grilles
Keep filter changes on schedule between cleans, 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. Overloaded filters let more dirt through to the coils and fan.
Honest limits
In fairness, there are a few things this work will not fix:
- Mechanical faults with motors, belts or bearings
- Airflow problems caused by the system’s design
- Ductwork downstream of the unit, which is a separate clean

Do you clean school ventilation in Leigh-on-Sea in the holidays?
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 Leigh-on-Sea. Send us your term dates when you give us a ring on 0345 646 2711 or use the quote form, and we will fit the work in.
Do you work in villages like Leigh-on-Sea?
Yes. Leigh-on-Sea is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
Which parts of an air handling unit do you clean?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
How long does an AHU clean take?
Cleaning takes anything from half a day for one small unit to several shifts for a plant room full of them. Large plant can be split over several shifts, and you can call us on 0345 646 2711 or use the quote form to plan it.
What about areas you cannot get to?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
What do you need from me for a quote?
Some pictures and a quick description of the system, with the address and opening hours. If we need more, we’ll ask.
Do you work with multi-site operators?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
Can you quote from pictures?
Yes, for many jobs. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote usually follows within one working day. If pictures aren’t enough, we’ll survey first.

What else we do in Leigh-on-Sea
The process
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. For a site near Leigh-on-Sea, the work is booked around your opening hours, evenings and weekends included.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Move anything stored near the system
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us about site rules, permits or sign-in

Landlords, agents and facilities managers
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
What AHU cleaning looks like in Leigh-on-Sea
There are about 10 schools, colleges and universities and about 45 caring premises (care homes, nurseries and hospitals) on the FSA’s food hygiene register across Leigh-on-Sea and its immediate surroundings (about a mile and a half). Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Leigh-on-Sea, about 32 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site. Chartwell Private Hospital is the nearest hospital, about 0.7 miles west of Leigh-on-Sea. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
If you manage offices or shops near Leigh-on-Sea station, their ventilation can be inspected and cleaned out of hours. Wherever a school like West Leigh Infant School has ducted ventilation, a half-term visit keeps the work out of lesson time. Chartwell Private Hospital, about 0.7 miles west, is the nearest hospital to Leigh-on-Sea, and healthcare sites of every size need their supply air kept clean.

What your team can do, and what needs us
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
How we price AHU cleaning
We do not publish a price list, because no two systems are the same. What we look at:
- Parking and loading at the site
- Working hours and out-of-hours timing
- Whether several sites go on one quote
- The size of the system
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will go through it with you.
Helping us quote
We can often survey from pictures. Try to include:
- Your opening hours and when the area is out of use
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The postcode and the type of business
- Any access panels or hatches you can see
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
