Little Wigborough questions
Is AHU cleaning available in Little Wigborough?
Yes, Little Wigborough is covered. A fixed quote usually follows within one working day of the survey details.
Do you work overnight in Little Wigborough?
Yes, nights and weekends are routine for us. The site is handed back ready to open. When you call us on 0345 646 2711 or drop us a line, mention when the site is quiet.
How much notice do you need?
Earlier is better, particularly for night and weekend visits. Quotes normally come back within one working day, and emergencies are covered by our 24/7 line.
Do you look at the system first?
Yes. We always survey first, either from pictures and details you send or on a site visit. Then you get a fixed quote.
Will you repair the fan or motor?
We clean the unit and flag faults rather than repair them, with pictures where it helps.
Do you give a certificate after the clean?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
How do you keep the site clean during the work?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
AHU cleaning in Little Wigborough
Our AHU cleaning covers sites in Little Wigborough and the rest of Essex, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. The work covers supply and extract fans, heating and cooling coils and drain trays, and the jobs we see most are debris and leaves in the fresh air intake and stale or musty smells from the ventilation.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

The process
Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Somewhere as small as Little Wigborough, the date and timings are agreed with you well before the day.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Name a contact who can let us in at the agreed time
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
How to get a quote
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, call us on 0345 646 2711 or use the quote form.

Aftercare tips
So the system stays in good health:
- Keep inspection doors on the unit in good order
- Don’t store bins or materials near the intake
- Check the drain tray is emptying during routine visits
- Keep filter changes on time and recorded
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.

How we price AHU cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- Parking and loading at the site
- Any permits to work or inductions
- Whether several sites go on one quote
- The times the site is available
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. Call for a fixed quote and we will explain each part.
What to send for a quote
Before you ask for a quote, gather:
- Where the site is and what kind of site it is
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Wide photos of the system and the area around it
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before work begins.
Staff cleaning versus specialist work
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
What a clean will not put right
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
- Coils that are corroded or leaking and need replacing
- A system that’s undersized for the building
Not sure which it is? You can phone us on 0345 646 2711 or use the quote form and we’ll tell you honestly before you book.
Where we work
- Filter sections
- Drain trays
- Internal panels
- Heating and cooling coils
- Supply and extract fans
- Dampers and louvres
What we’re called out for in Little Wigborough
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Clients usually contact us when they notice one of these:
- Intake sections clogged with outdoor debris
- Units that have only ever had filter changes
- Condensate trays that won’t empty
- Air handling units with blocked filters
Around Little Wigborough, as anywhere, ventilation cleaning begins with an inspection.
What your quote should include
- How they set the interval to the next visit
- What happens if part of the system cannot be accessed
- Whether the quote is based on a survey or pictures
- Whether the whole system is included, or only the parts that are easy to reach
What the work involves, part by part
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
