AHU cleaning in Folkestone, done properly
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from photos or a site visit, and give you a fixed quote before any cleaning starts. If you have debris and leaves in the fresh air intake and odours coming through the supply air, we can help.
Buildings in towns like Folkestone often have ventilation added in stages, with units on the roof or in a plant room. An inspection shows which parts need cleaning.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

For landlords and multi-site operators
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
What affects the cost of AHU cleaning
The quote reflects the site in front of us. We take into account:
- Parking and loading at the site
- A single visit or a regular plan
- The times the site is available
- How many systems or sites are involved
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
Helping us quote
Photos and a few facts are often enough to price the work. Useful things to send:
- The times we could work without disrupting the site
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any access panels or hatches you can see
- The paperwork from the last visit, if you have it
Quotes are quick. Call or email with a few details and you’ll typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Report water on the plant room floor
- Make sure condensate is draining away
- Plan the next inspection before the last report gets filed away
- Clear leaves and litter away from the intake
Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to make sure it stays clear.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.
What staff can safely do
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
What we do, step by step
A visit follows the same order every time: protect the area, make the system safe, do the work, clear away and hand over the paperwork. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. A few pictures of the system and its access points help us plan a visit in Folkestone.
- We survey the unit from pictures or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- 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 pictures.
How to prepare
- Tell us about site rules, permits or sign-in
- Clear the space around the work
- Let us know when the site is closed or quiet
How to get a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

AHU cleaning around Folkestone
The FSA’s food hygiene register lists about 11 schools, colleges and universities, about 23 care, childcare and hospital premises and about 12 hotels and B&Bs with registered kitchens or food service in Folkestone and the streets around it, up to about 1.5 miles out. Busy, occupied buildings like these are where clean supply air matters most. Royal Victoria Hospital is the nearest hospital, about under half a mile north-east of Folkestone.
