How we handle AHU cleaning in Winchmore Hill
Our AHU cleaning covers sites in Winchmore Hill and the rest of Buckinghamshire, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers drain trays, internal panels and heating and cooling coils, and people most often call us about rooms that smell stuffy when the system runs and air handling units never cleaned inside.
In a village or hamlet like Winchmore Hill, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Nothing is signed off by word of mouth: 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.

Part by part
Internal casing and panels
We open each section through its doors and close them securely when we are done, and check every one is shut.
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and clean the filter housing.
How the visit works
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes half a day to a full day per unit, with large plant planned over several shifts. Somewhere like Winchmore Hill, lanes, gates and parking are worth mentioning in advance.
- We agree a shutdown window that suits the building.
- We take before photos 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.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Tell us about site rules, permits or sign-in
- Move anything stored near the system
- Let us know how we reach the system, including roofs, risers and plant rooms
Getting a quote
To help us quote: where the site is, what it is and its opening hours, a few pictures and any previous report or certificate. Once you have those, phone us on 0345 646 2711 or use the quote form.

Staff cleaning versus specialist work
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
When something else is needed
We’ll always give you a straight diagnosis, so here’s what this work cannot put right:
- Controls and BMS settings that run the unit
- Breakdowns that need a mechanical engineer
- Coils that are corroded or leaking and need replacing
Not sure which it is? You can ring 0345 646 2711, or send details by email and we will tell you honestly.
What we work on in Winchmore Hill

Fixed quotes for AHU cleaning in Winchmore Hill
The diagnosis comes before the price. We look at:
- One-off work versus a regular cycle
- The number of sites or systems
- When the work can happen, such as evenings, overnight or weekends
- Site rules, permits and inductions
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before work begins.
What to send for a quote
You do not need the technical terms. It helps if you can send:
- Any previous report or certificate
- When the site is open and when it’s quiet
- Detail shots of panels, filters and grilles
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Photos are enough for some jobs, while others need a look on site. 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.

Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Plan the next inspection before the last report gets filed away
- Keep the area around the fresh air intake clear
- Flag stale or damp smells in the supply air
- Note any water around the unit or leaks below it
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
Winchmore Hill: your questions answered
Do you do school ventilation cleaning in Winchmore Hill in the summer holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Winchmore Hill. Send us your term dates when you phone us on 0345 646 2711 or use the quote form, and we’ll fit the work in.
Do you cover smaller places like Winchmore Hill?
Yes, we work in villages as well as towns, and Winchmore Hill is covered. Just mention lanes, gates or anything else about the site when you book.
Can you fix a faulty AHU?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report so your maintenance contractor can deal with it.
Do you work evenings or weekends?
Yes, wherever it helps the building. Tell us when the unit can go off and we’ll work to that.
Do you look at the system first?
Yes. We always survey first, from your pictures and details, or with a visit where needed. A fixed quote follows.
How long will the unit be out of action?
It takes from a few hours for a compact unit to a day or more for a large one. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
What happens if you can’t reach some of it?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
For landlords and multi-site operators
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
