AHU cleaning in Hyde farm estate, 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 pictures, so you can see the unit’s condition for yourself. The work covers internal panels, drain trays and heating and cooling coils, and common reasons people get in touch are intake sections clogged with outdoor debris and condensate trays that won’t empty.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so work in Hyde farm estate is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
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. It shows what was done and what, if anything, couldn’t be reached.

Your questions about AHU cleaning in Hyde farm estate
Can a school’s ventilation in Hyde farm estate be done out of term time?
Yes, out-of-term visits are normal for schools. There are about 50 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Hyde farm estate. Send us your term dates when you ring 0345 646 2711, or send details by email, and we’ll fit the work in.
Can parking be tricky for a job in Hyde farm estate?
A loading bay, a visitor permit or off-street space near the site in Hyde farm estate makes the visit easier to plan. Night visits tend to make loading easier on London streets.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
What happens if you cannot reach some of it?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
Is there a report after cleaning?
Yes. You get a TR19® certificate plus before and after photos. Keep them in the maintenance log.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Call us any time and explain what’s happened.
What happens to the waste?
We take it away when we go. During the work, it’s contained to keep the area clean.
Do you repair air handling units?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We will flag anything we notice during the clean.

Healthcare buildings such as St James' Hospital, about 1 mile west, depend on their ventilation; if you manage a surgery, clinic or care home near Hyde farm estate, yours matters too.

What affects the cost of AHU cleaning
The survey tells us what the work involves. We look at:
- One-off work versus a regular cycle
- The number of sites or systems
- Working hours and out-of-hours timing
- Site requirements such as sign-in and permits
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and why the quote is fixed before we start.
What to send for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- A few general shots of the system
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any previous report or certificate
- Your opening hours and when the area is out of use
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
Leave it or put it right?
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. Every month a London system goes without attention adds to what has to be done later.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.

What the work involves, part by part
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards before the unit is handed back.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
The process
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before we start, and the area around the work is covered and protected. On site, it takes anything from half a day for one small unit to several shifts for a plant room full of them. If your building in Hyde farm estate has sign-in rules, permits or key holders, mention them when you book.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after photos.
Preparing for the visit
- Let us know about permits to work or site inductions
- Plan for cooking equipment or plant to be off before we arrive
- Agree a time when the area can be out of use
Ask for a quote
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before we start.
Advice
What your team can do, and what needs us
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
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.
