About our AHU cleaning in Wrotham

Our AHU cleans for sites in Wrotham 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. Common call-outs are for odours coming through the supply air and dirty fans and fan housings, on internal panels, dampers and louvres and heating and cooling coils.

For a building in or near Wrotham, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.

Each visit ends with a written report and photos, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Ventilation in Wrotham buildings

There are about 8 schools, colleges and universities and about 3 hospitals, care homes and childcare premises on the FSA’s food hygiene register across Wrotham and its immediate surroundings (about a mile and a half). Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Wrotham’s nearest hospital, Sevenoaks Hospital, is about 5.1 miles west. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. About 22 miles out from central London, Wrotham is part of the South East area we work across. Evening, overnight and weekend visits are all possible.

Healthcare ventilation, from large hospitals like Sevenoaks Hospital (about 5.1 miles west) to small clinics, depends on clean filters, coils and ducts.

The process

The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes a single shift for a typical unit, longer for large or heavily soiled ones, and we clear up before we go. Pictures of the system and its access let us plan the work in Wrotham before we set off.

  1. We survey the unit from photos or on site and agree what’s included.
  2. We arrange the shutdown with your staff and sheet the area.
  3. Filters are dealt with as agreed, and the coils, fan and casing cleaned.
  4. Drain trays are cleared and cleaned and the outlet checked.
  5. A TR19® certificate and photo report follow the clean.

How to prepare

  • Dig out any earlier paperwork for the system
  • Move anything stored near the system
  • Let us know about parking and loading

What happens if it’s left?

Standing water in a drain tray doesn’t clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. Somewhere as small as Wrotham, losing a kitchen or building to a fault is felt by everyone who uses it.

What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before any work starts, so you know where you stand.

Fixed quotes for AHU cleaning in Wrotham

A fixed price needs a few facts first. We check:

  • One-off work versus a regular cycle
  • Any permits to work or inductions
  • Travel, parking and unloading
  • What state the system is in

The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before work begins.

What to send for a quote

There’s no need for technical detail. It helps if you can send:

  • Any symptoms, from odd noises to smells or leaks
  • When the site is open and when it’s quiet
  • The site address and the type of premises
  • Close-ups of filters, grilles, hatches or access panels

For a fixed quote, call 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.

Looking after it afterwards

Looking after the system between visits is straightforward, and it helps at the next visit:

  • Don’t ignore odours coming through the grilles
  • Make sure the unit’s access doors open easily
  • Check the drain tray is emptying during routine visits
  • Note any water around the unit or leaks below it

The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.

Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.

FAQs for Wrotham

Can a school’s ventilation in Wrotham be done out of term time?

Yes. Half-terms and the summer break are the natural time for school work. There are about 8 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Wrotham. Send us your term dates when you call 0345 646 2711, or send details by email, and we will fit the work in.

Do you work overnight in Wrotham?

Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Let us know the hours you are closed and we will book within them.

What do you clean inside the unit?

Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.

Is there a survey before the work?

Yes. We always survey first, from your photos and details, or with a visit where necessary. A fixed quote follows.

Are you insured?

Yes, we’re fully insured. We also hold CHAS and SafeContractor, for sites that check contractor safety.

How long does it take to clean an air handling unit?

It takes half a day to a full day per unit, with large plant planned over several shifts. Size, layout and how dirty it is decide the rest, and we’ll confirm the time when we quote.

What if parts of the system can’t be reached?

The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.

Do you do ventilation duct cleaning too?

Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.

Signs you need AHU cleaning in Wrotham

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, a little more each month.

It’s time to book a visit if you see:

  • Filters that are clogged or overdue
  • Units that have only ever had filter changes
  • Air handling units due a clean after building work
  • Fan sections that haven’t been cleaned in years

For schools like Wrotham School, the holidays are the usual time to inspect and clean ventilation.

Questions to ask before booking

  • Whether the whole system is included, or only the parts that are easy to reach
  • Whether the figure could change on the day
  • What records you’ll receive afterwards
  • Whether inaccessible sections are listed on the report

How the job changes from site to site

Fans and fan sections

Before the fan is touched, the unit is shut down and made safe in agreement with the site.

Filters

Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.

Honest limits

Before booking, it helps to know what’s not included:

  • Building management system faults
  • Ventilation that was badly designed in the first place
  • The supply and extract ducts, quoted separately

If in doubt, phone us on 0345 646 2711, or send details by email and we’ll say what we think before booking.
