What we’re called out for in Vernham Street
Whatever surrounds a building in Vernham Street, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and some travels further into the unit.
What we’re most often called out for:
- Rooms that smell stuffy when the system runs
- Units needing a clean before a new tenant or handover
- Condensate trays that won’t empty
- Dirty filters cutting the airflow

AHU cleaning in Vernham Street
We clean air handling units for buildings in Vernham Street 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. Typical jobs include debris and leaves in the fresh air intake and dust built up on fan impellers, across filter sections, heating and cooling coils and supply and extract fans.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
The report is your system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Staff cleaning versus specialist work
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.

What happens on the day
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. From there, it takes half a day to a full day per unit, with large plant planned over several shifts. Somewhere as small as Vernham Street, the date and timings are agreed with you well before the day.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area 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.
- You get a TR19® certificate and a photo report.
How to prepare
- Find the previous report, if there is one
- Tell us the best time to work, such as after service or at a weekend
- Name a contact who can let us in at the agreed time
Getting a quote
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.
Advice
How we price AHU cleaning
You will get a fixed price before any work starts. It’s based on:
- The scale of the work
- When the work can happen, such as evenings, overnight or weekends
- The condition of the system
- Access, including roofs, risers and ceiling voids
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, call us on 0345 646 2711, or email photos for straight advice and a fixed quote.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Detail shots of panels, filters and grilles
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to

Different parts, different methods
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. The intake section gets particular attention.
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.

FAQs for Vernham Street
Is Vernham Street within the area you cover?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Can you work in Vernham Street outside opening hours?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Just ring 0345 646 2711 or email us with your opening times and we’ll plan around them.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Do you give a certificate after the clean?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
Is there a survey before the work?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, plus pictures of the system and your last certificate or report if you have one.
Does the AHU have to be shut down for cleaning?
Yes. We cannot clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
What happens if it’s left?
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. Rural sites can’t always move to another kitchen or room when something fails.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
