AHU cleaning for kitchens and businesses in Wymering
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. Typical jobs include units needing a clean before a new tenant or handover and blocked condensate drains and slimy trays, on drain trays, supply and extract fans and internal panels.
For a building near Wymering, the visit is planned around how it’s used, and the journey is planned ahead. The method doesn’t change: inspect first, clean, then record what was done.
Every visit ends with a written report and pictures, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Wymering buildings and their air
Food Standards Agency records list about 15 schools, colleges and universities, about 26 care, childcare and hospital premises and about 6 hotels and B&Bs registered as food businesses in Wymering and the streets around it, up to about 1.5 miles out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. For Wymering, the closest hospital is Queen Alexandra Hospital, roughly less than half a mile north-east. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
Hospitals such as Queen Alexandra Hospital (about less than half a mile north-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Wymering are no different. If you manage shops or offices close to Cosham station, a TR19® Air inspection shows whether the ductwork needs cleaning. Classrooms and halls at schools such as Medina Primary School are easiest to work in when pupils are away.

Why deal with it now?
Standing water in a drain tray does not clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. Booking now means the visit to Wymering is planned around you, not forced by a breakdown.
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before we start.
Why Wymering businesses choose us
- Fully insured
- Fixed quotes from a survey or photos
- Trading since 2009
- Work around your opening hours, with 24/7 emergency cover

For landlords and multi-site operators
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
Facilities teams in offices, schools and healthcare sites book us too in Wymering and across Portsmouth. Work can be phased by floor, building or site to keep disruption down.
Between visits
Looking after the system between visits is straightforward, and it helps at the next visit:
- Watch for drips or damp patches near the plant
- Keep the area around the fresh air intake clear
- Check the drain tray is emptying during routine visits
- Report stiff or damaged access doors
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
Different parts, different methods
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins are not damaged.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey, before we quote.
What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, and that takes from a few hours for a compact unit to a day or more for a large one. Because the survey comes first, a visit to Wymering can normally be finished without a second trip.
- 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.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Have your last certificate or report to hand
- 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
How to get a quote
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To start, call us on 0345 646 2711 or drop us a line.

Your questions about AHU cleaning in Wymering
Do you do school ventilation cleaning in Wymering in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 15 schools and colleges with food registrations within roughly a mile and a half of Wymering. Tell us your holiday dates and we will book the visit for when the site is empty.
Do you work overnight in Wymering?
Yes. We work evenings, overnight and at weekends. The work in Wymering can fit around your hours. Tell us your opening hours when you ask for a quote.
What happens if you cannot reach some of it?
Anything we cannot reach goes on the report, with photos where possible, and we tell you what would make it reachable, for example new access panels.
What’s TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
How much does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. For a quote, phone us on 0345 646 2711 or send us an email with the site type, opening hours and a few photos.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Ring any time and tell us what’s happened.
Is there a report after cleaning?
Yes, both a certificate and a report with photos. It includes a recommended date for the next check.
Which sectors do you work in?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
What affects the quote in Wymering
We quote each job individually. This is what makes a difference:
- Access, including roofs, risers and ceiling voids
- Site requirements such as sign-in and permits
- What state the system is in
- One-off work versus a regular cycle
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 make a difference.
Helping us quote
Photos let us diagnose from a distance. The most useful are:
- The paperwork from the last visit, if you have it
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The site address and the type of premises
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
