Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
About our AHU cleaning in Hawley
Our AHU cleans for sites in Hawley 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. We are often asked to deal with units that have only ever had filter changes and stale or musty smells from the ventilation, across dampers and louvres, heating and cooling coils and drain trays.
Work in a small place like Hawley starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Aftercare tips
Think of this as the after-treatment advice, short and simple:
- Keep the certificate and photo report with the plant records
- Stick to the filter change plan
- Make sure condensate is draining away
- Keep the area around the fresh air intake clear
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.
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.
Hawley buildings and their air
Going by the FSA’s register, there are about 11 schools, colleges and universities, about 24 caring premises (care homes, nurseries and hospitals) and about 3 hotels, B&Bs and guest houses serving food within about 1.5 miles of central Hawley. Busy, occupied buildings like these are where clean supply air matters most. Hawley, about 15 miles from central London, is within our usual area. A survey and a fixed quote come first, then the visit at a time that suits you. About 1.7 miles north-east of Hawley is Darenth Park Hospital, the nearest hospital. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
If you run a surgery, dental practice or care home near Hawley, clean ventilation matters as much to you as to a hospital like Darenth Park Hospital (about 1.7 miles north-east). Wherever a school like Sutton-At-Hone Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Hawley is about 1 mile south of Dartford, in Kent. Across the DA2 area, we cover AHU cleaning for commercial sites. Hawley is one of 922 towns, villages and districts in Kent we cover for commercial clients. There’s also a page for London, about 15 miles away.

Neighbouring places we cover for AHU cleaning include Clement Street (1 mile south-west), Sutton at Hone (1 mile south-east), Darenth (1 mile east), Dartford (1 mile north) and St Margarets (2 miles south-east).

What’s near Hawley
Around Hawley, our work takes us to kitchens and buildings near Darenth Country Park, Leigh Academy and The Four Lymes pub. The nearest railway station is Farningham Road station, about 1.5 miles south. A little further out are Bluewater (2.4 miles north-east) and Darenth Park Hospital (1.7 miles north-east). The countryside around Hawley includes Wansunt Pit and Sawyers Lake.
Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
What the work involves, part by part
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey, before we quote.
Honest limits
Not every problem is solved by AHU cleaning, and we’ll tell you before work begins. It will not put right:
- Ventilation that was badly designed in the first place
- Coils that are corroded or leaking and need replacing
- The supply and extract ducts, quoted separately
If you are not sure, just call 0345 646 2711 or use the quote form and we will give you a straight answer before booking.

What else we do in Hawley
The process
Each visit runs to the same pattern: sheeting and protection first, make the system safe, carry out the AHU cleaning, tidy up and hand over the paperwork. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Somewhere as small as Hawley, the date and timings are agreed with you well before the day.
- We survey the unit from photos or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- 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.
Getting ready for the visit
- Mention any sign-in, permit or induction we need
- Let us know about parking and loading
- Move anything stored near the system
Get a fixed quote
We do not publish a price list, because every site is different. We look at your system first, from photos or on a visit, and then send you a fixed quote. To start, give us a ring on 0345 646 2711 or send us an email.
Advice
What affects the cost of AHU cleaning
The price is fixed before any work begins. It takes into account:
- Where the site is and how we reach it
- The times the site is available
- Any permits to work or inductions
- How big the system is
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so you know where you stand.
Helping us quote
When you call or email, these details help:
- How we’d reach plant on a roof or in a plant room
- The times we could work without disrupting the site
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Where the site is and what kind of site it is
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.
