How we handle AHU cleaning in North Crawley
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. If you’re dealing with drain trays holding standing water and units needing a clean before a new tenant or handover, we can put it right, from dampers and louvres, supply and extract fans and heating and cooling coils onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

The process
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before any work starts, and floors and nearby surfaces are sheeted. On site, it takes one overnight shift for many single units, with bigger plant phased. Photos of the system and how to reach it help us plan a visit to North Crawley.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after photos.
Preparing for the visit
- Move anything stored near the system
- Let us know about permits to work or site inductions
- Mention any parking or loading restrictions
Ask for a quote
To help us quote: where the site is, what it is and its opening hours, a few photos and any previous report or certificate. Once you have those, call 0345 646 2711 or send us an email.

Your questions about AHU cleaning in North Crawley
Can you do AHU cleaning in North Crawley?
Yes. We work across London and the South East, and North Crawley is part of that. Get in touch with the details and we’ll arrange a survey.
Will you come out to North Crawley?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
What should I send you?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply ring 0345 646 2711, or send details by email.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7, for problems that can’t wait. Call us any time and explain what’s happened.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.

The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
What the work involves, part by part
Drain trays
Drain trays can rust and leak over time. We record their condition with photos so you can decide on any repairs.
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.
What affects the quote in North Crawley
Sites vary more than people expect. The main factors:
- The times the site is available
- Access, including roofs, risers and ceiling voids
- One-off work versus a regular cycle
- The size of the system
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.
What we need to know
Many jobs can be priced from photos and some basics. Useful things to send:
- Your opening hours and when the area is out of use
- How we’d reach plant on a roof or in a plant room
- Your last certificate, test record or report
- The postcode and the type of business
For AHU cleaning in North Crawley, give us a ring on 0345 646 2711, or send details by email. Let us know the site type and the opening hours, plus pictures or the previous report if they’re to hand. A fixed quote typically follows within one working day.
What your team can do, and what needs us
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Managing agents and facilities teams in North Crawley
Facilities teams in offices, schools and healthcare sites book us too across Milton Keynes. Larger estates can be phased building by building around the people who use them.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.

Common problems we fix in North Crawley
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Any of these means the system needs a check-up:
- Rooms that smell stuffy when the system runs
- Condensate trays that will not empty
- Fan sections that haven’t been cleaned in years
- Intake sections clogged with outdoor debris
School buildings such as North Crawley CofE School are usually done in the holidays, so classrooms aren’t disturbed.
