How we handle AHU cleaning in Ladwell
If the units serving a building in Ladwell have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. If you’re dealing with intake sections clogged with outdoor debris and dirty coils holding back the airflow, we can help, from internal panels, heating and cooling coils and supply and extract fans onwards.
Work in a small place like Ladwell starts with agreeing access and timings.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Ladwell buildings and their air
Food Standards Agency data includes about 3 schools, colleges and universities and about 6 caring premises (care homes, nurseries and hospitals) within 1.5 miles or so of the middle of Ladwell. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Romsey Community Hospital is the nearest hospital, about 4.2 miles west of Ladwell. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
Romsey Community Hospital, about 4.2 miles west, is the nearest hospital to Ladwell, and healthcare sites of every size need their supply air kept clean.
Ladwell is about 2 miles north of Chandler's Ford, in Hampshire. Sites in Ladwell get the same service as everywhere we cover: diagnosis first, a fixed price, out-of-hours working where necessary and a written report with pictures. We cover 683 places across Hampshire, from busy centres to quieter spots. There’s also a page for Southampton, about 7 miles away.
All of SO21 is within our area for AHU cleaning, from the main roads to the quietest streets.

Around Ladwell
We work in commercial kitchens and buildings around Thornden School and The Dolphin Inn, among other places. Ladwell’s nearest station is Chandlers Ford station, roughly 2 miles south. Well-known places in the area include Winchester Castle (4.6 miles north-east) and Romsey Community Hospital (4.2 miles west). For a walk, there’s Flexford Nature Reserve.
Keeping the system healthy
Looking after the system between visits is straightforward, and it helps at the next visit:
- Do not ignore odours coming through the grilles
- Book the next check in line with the report
- Make sure condensate is draining away
- Note any water around the unit or leaks below it
When we have closed the unit up, it can be restarted with your site team. 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.

Multi-site and managed buildings
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
What happens on the day
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. If you can send pictures, we can arrive in Ladwell knowing what to expect.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Tell us where we can park and unload
- Name a contact who can let us in at the agreed time
- Tell us the best time to work, such as after service or at a weekend

Related advice
Staff cleaning versus specialist work
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
How the job changes from site to site
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with pictures.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.
Do you need AHU cleaning in Ladwell?
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Common reasons sites call us are:
- Blocked condensate drains and slimy trays
- Odours coming through the supply air
- Units needing a clean before a new tenant or handover
- Dirty coils holding back the airflow
Wherever a school like John Keble Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Common questions in Ladwell
Can you get to a site in Ladwell?
Yes. Ladwell is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you clean school ventilation in Ladwell in the holidays?
Yes. The holidays are the usual time for school work. There are about 3 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Ladwell. Send us your term dates when you ring 0345 646 2711 or use the quote form, and we’ll fit the work in.
Do you offer emergency callouts?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
Will we get paperwork for the AHU clean?
Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.
How often should an air handling unit be cleaned?
That is set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
Can you clean the ducts connected to the AHU?
Yes, the ductwork, grilles and diffusers the unit serves. We’ll tell you after the survey whether the ducts need it.
What happens to the waste?
It leaves the site with us when we go. While we work, it’s kept contained to keep the area clean.
How much notice do you need?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
Why act early in Ladwell
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. Equipment tucked in a roof space or outbuilding near Ladwell rarely gets looked at unless someone books it.
What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before we start.
