Why it’s worth doing now in Segensworth
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. Our emergency line runs 24/7, but a planned visit to Segensworth is calmer for everyone.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.

AHU cleaning for kitchens and businesses in Segensworth
Our AHU cleaning covers sites in Segensworth and the rest of Hampshire, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you are dealing with plant that needs cleaning after a refit and stale or musty smells from the ventilation, we can put it right, from supply and extract fans, internal panels and dampers and louvres onwards.
Work in a small place like Segensworth starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
For insurers and inspectors, the record counts. 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.

When to call us in Segensworth
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. So a unit can be well maintained and still dirty.
Clients usually contact us when they notice something like this:
- Dust built up on fan impellers
- Condensate trays that will not empty
- Plant that has been serviced but not cleaned
- Intake sections clogged with outdoor debris
For schools like Cornerstone CofE (VA) Primary School, the holidays are the usual time to inspect and clean ventilation.
Before booking anyone
- Which accreditations they hold, and whether you can check them
- What paperwork you get at the end
- Whether they’re fully insured
- Whether the work can be done while the site is closed
In-house cleaning or a specialist?
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.

An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning won’t do:

- Ventilation that was badly designed in the first place
- Leaking heating or cooling coils

FAQs for Segensworth
Can you come to Segensworth after we close?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Just call us on 0345 646 2711, or send details by email with your opening times and we’ll plan around them.
Do you do school ventilation cleaning in Segensworth in the summer holidays?
Yes. The holidays are the usual 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 Segensworth. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can you fix a faulty AHU?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.
Do you have insurance?
Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.
What should I send you?
Where the site is, what it is and when it’s open, plus pictures of the system and your last certificate or report if you have one.
What’s included in an AHU clean?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
What happens if you cannot reach some of it?
The report shows them clearly. In ductwork, new access panels are often the answer, which we can install.
What is TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
How the visit works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes half a day to a full day per unit, with large plant planned over several shifts. We agree a date with you, plan the drive to Segensworth and turn up when the site is quiet.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Allow time for equipment near the work to be turned off and cool down
- Mention any sign-in, permit or induction we need

Keeping the system healthy
So the system stays in good health:
- Don’t ignore odours coming through the grilles
- Keep filter changes on time and recorded
- Plan the next inspection before the last report gets filed away
- Make sure the unit’s access doors open easily
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
