For landlords and multi-site operators
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 can quote for the whole system.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.

What affects the cost of AHU cleaning
You’ll get a fixed price before any work starts. It takes into account:
- The times the site is available
- Whether we need access equipment or extra panels
- Site rules, permits and inductions
- One-off work versus a regular cycle
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and why the quote is fixed before we start.
What to send for a quote
Photos let us diagnose from a distance. Try to include:
- Close-ups of filters, grilles, hatches or access panels
- Any symptoms, from odd noises to smells or leaks
- How we’d reach plant on a roof or in a plant room
- Any previous report or certificate
For AHU cleaning in Longstock, call us on 0345 646 2711 or send us an email. Tell us what kind of premises it is and when it’s open, and send pictures or your last report if you can. A fixed quote normally follows within one working day.
The process
Your staff do not need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. A few pictures of the system help us make the most of a visit to a place like Longstock.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Agree a time when the area can be out of use
- Let us know about parking and loading
- Plan for cooking equipment or plant to be off before we arrive

Advice
Common problems we fix in Longstock
Whatever surrounds a building in Longstock, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
It’s time to book a visit if you see:
- Dirty filters cutting the airflow
- Debris and leaves in the fresh air intake
- Units that have only ever had filter changes
- Fan sections that haven’t been cleaned in years
For schools like Test Valley School, the holidays are the usual time to inspect and clean ventilation.
What to look for in a quote
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the work can be done while the site is closed
- Whether inaccessible sections are listed on the report
- What paperwork you get at the end
Between visits
Here’s the after-treatment advice, in brief:
- Check the drain tray is emptying during routine visits
- Keep the certificate and photo report with the plant records
- Diary the inspection date recommended in the report
- Clear leaves and litter away from the intake
The report suggests a date for the next inspection or clean, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
What your team can do, and what needs us
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
