AHU cleaning for kitchens and businesses in Fleet
We clean air handling units for buildings in Fleet and across Hampshire, working to TR19® Air, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers filter sections, internal panels and supply and extract fans, and common reasons people get in touch are dirty filters cutting the airflow and rooms that smell stuffy when the system runs.
Buildings in towns like Fleet often have ventilation added in stages, with units on the roof or in a plant room. The work starts with an inspection to decide what needs cleaning.
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. It shows what was done and what, if anything, couldn’t be reached.

How the visit works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes one overnight shift for many single units, with bigger plant phased. A few pictures of the system and its access points help us plan a visit in Fleet.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Mention any locked doors, roof access or ceiling voids
- Move anything stored near the system
- Let us know when the site is closed or quiet
Ask for a quote
To help us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Once you have those, phone us on 0345 646 2711 or send us an email.

AHU cleaning around Fleet
There are about 8 schools, colleges and universities, about 19 hospitals, care homes and childcare premises and about 5 hotels and B&Bs on the FSA’s food hygiene register in and around Fleet, up to about a mile and a half out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. We cover Fleet, about 36 miles from central London, as part of our work across London and the South East. Evening, overnight and weekend visits are all possible. Fleet’s nearest hospital, Fleet Community Hospital, is about 1 mile north-west. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
Classrooms and halls at schools such as Heatherside Junior School are easiest to work in when pupils are away.
Fleet is about 13 miles south-east of Reading, in Hampshire. Sites in Fleet get the same service as everywhere we cover: diagnosis first, a fixed price, out-of-hours working where necessary and a written report with photos. Across Hampshire, we cover 683 places, Fleet among them. We also work in Guildford, around 12 miles away.
We work across the GU51, GU52 and GU10 postcode area for AHU cleaning and the streets around it. Streets in the area include Church Road, Durnsford Avenue and Hankins Court, and we cover them all for AHU cleaning. With the A323 and A3013 close by, Fleet is easy for our technicians to reach at any hour. Close by, we work in Church Crookham (1 mile south-east), Crookham Village (1 mile west), Elvetham Heath (1 mile north-west), Dogmersfield (2 miles west) and Elvetham (2 miles north-west). We also work in nearby towns such as Basingstoke (11 miles west), Farnborough (3 miles north-east), Aldershot (4 miles south-east), Alton (10 miles south-west), Yateley (4 miles north) and Tadley (14 miles north-west). Fleet is among the bigger places we cover in Hampshire for AHU cleaning.
What’s near Fleet
Locally, jobs take us to businesses close to Court Moor School, The Prince of Wales pub and School. For rail, the closest station is Fleet station, roughly 1.2 miles north. A little further out are Royal Army Dental Corps Historical Museum (3.9 miles east) and Fleet Community Hospital (1 mile north-west). Open spaces near Fleet include Fleet Pond Nature Reserve and Hitches Hill.
Different parts, different methods
Internal casing and panels
We open each section through its doors and close them securely when we’re done, and check every one is shut.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
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 can diagnose it and quote.
What affects the cost of AHU cleaning
Your quote is based on your site. We consider:
- Any permits to work or inductions
- The condition we find in the survey
- One-off work versus a regular cycle
- Whether several sites go on one quote
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.
Helping us quote
To help us quote quickly, please include:
- Wide photos of the system and the area around it
- The times we could work without disrupting the site
- Any symptoms, from odd noises to smells or leaks
- Any previous report or certificate
For AHU cleaning in Fleet, call us on 0345 646 2711 or use the quote form. Tell us what kind of premises it is and when it’s open, and send photos or your last report if you can. We typically send a fixed quote within one working day.
Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
Why act early in Fleet
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. Each month of use adds to the build-up, so a site in Fleet is better off booking it now.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we will price it together.

When to call us in Fleet
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
Any of these means the system needs a check-up:
- Stale or musty smells from the ventilation
- Plant that has been serviced but not cleaned
- Dust-coated heating and cooling coils
- Fan sections that haven’t been cleaned in years
Fleet Community Hospital, about 1 mile north-west, is the nearest hospital to Fleet, and healthcare sites of every size need their supply air kept clean.
Before you book anyone
- Whether VAT is included
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- When they can work, and whether that’s outside your opening hours
- Whether a survey comes first
