AHU Cleaning in Hazelwood
Specialist AHU cleaning for Hazelwood: a survey, a fixed price, careful work and proper paperwork. Ask us for a fixed quote.
- Plant that needs cleaning after a refit
- Plant that has been serviced but not cleaned
- Intake sections clogged with outdoor debris
Different parts, different methods
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
AHU cleaning for kitchens and businesses in Hazelwood
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, once the unit has been shut down and isolated. The work covers dampers and louvres, supply and extract fans and heating and cooling coils, and the jobs we see most are plant that has been serviced but not cleaned and coils clogged with dust and debris.
In a village or hamlet like Hazelwood, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Every visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning will not do:
- Building management system faults
- Coils that are corroded or leaking and need replacing
- Airflow problems caused by the system’s design
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we will tell you honestly before you book.
Parts of the system we cover
- Dampers and louvres

- Heating and cooling coils
- Drain trays
- Filter sections
- Supply and extract fans
In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
How we price AHU cleaning
The survey tells us what the work involves. The main factors are:
- How many systems or sites are involved
- Site rules, permits and inductions
- What state the system is in
- Where the site is and how we reach it
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will go through it with you.
What we need to know
A few details help us quote accurately. With your enquiry, please include:
- Wide pictures of the system and the area around it
- The paperwork from the last visit, if you have it
- The roof, plant room or outside wall the system runs to
- When the site is open and when it’s quiet
For a fixed quote, ring 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You will usually have a quote within one working day.
Why it’s worth doing now in Hazelwood
Standing water in a drain tray does not clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. It’s worth booking a check, because nobody sees inside a duct day to day.
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.

What AHU cleaning looks like in Hazelwood
Orpington Hospital is the nearest hospital, about 2.1 miles north-east of Hazelwood. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Hazelwood, about 14 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site.
Healthcare ventilation, from large hospitals like Orpington Hospital (about 2.1 miles north-east) to small clinics, depends on clean filters, coils and ducts. If you manage a school such as Downe Primary School, ventilation cleaning is best booked for the holidays.

Common questions in Hazelwood
Can you come to Hazelwood after we close?
Yes, nights and weekends are routine for us. That way a site in Hazelwood doesn’t have to lose a day’s trading. Let us know the hours you are closed and we’ll book within them.
Is Hazelwood within the area you cover?
Yes, we work in villages as well as towns, and Hazelwood is covered. Photos of the system and directions to the site help us plan the visit.
What do you do to protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Is there a report after cleaning?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
Is a quote from photos possible?
Yes, where the photos show enough. If not, a site survey comes first, then a fixed quote.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
Does the AHU have to be shut down for cleaning?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
What happens on the day
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes anything from half a day for one small unit to several shifts for a plant room full of them, and we clear up before we go. Somewhere like Hazelwood, lanes, gates and parking are worth mentioning in advance.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any sign-in, permit or induction we need
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
We don’t publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To start, call us on 0345 646 2711 or drop us a line.

For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
