How the job changes from site to site
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. The intake section gets particular attention.
How we handle AHU cleaning in Haverstock
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers dampers and louvres, internal panels and supply and extract fans, and common reasons people get in touch are units that have only ever had filter changes and drain trays holding standing water.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. An inspection first shows where cleaning is needed in a building in Haverstock.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

How we price AHU cleaning
The survey tells us what the work involves. We look at:
- Travel, parking and unloading
- One-off work versus a regular cycle
- Whether we need access equipment or extra panels
- Whether several sites go on one quote
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, call us on 0345 646 2711 or email us for straight advice and a fixed quote.
What to send for a quote
You do not need the technical terms. It helps if you can send:
- The times we could work without disrupting the site
- Close-ups of filters, grilles, hatches or access panels
- The paperwork from the last visit, if you have it
- Where the site is and what kind of site it is
To get a fixed quote, phone us on 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. We usually come back within one working day.
What happens on the day
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. Equipment that has to be off is switched off and allowed to cool before we start, and floors and nearby surfaces are sheeted. The work itself takes one overnight shift for many single units, with bigger plant phased. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in Haverstock.
- 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.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Clear loose items from the work area
- Mention any sign-in, permit or induction we need
- Find the previous report, if there is one

Getting a quote does not take long. Call or email with a few details and you will usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Advice
For landlords and multi-site operators
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
In-house cleaning or a specialist?
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
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.
AHU cleaning around Haverstock
The FSA’s food hygiene register lists about 71 schools, colleges and universities, about 59 caring premises (care homes, nurseries and hospitals) and about 30 hotels and B&Bs with registered kitchens or food service within 1.5 miles or so of the middle of Haverstock. Busy, occupied buildings like these are where clean supply air matters most. Haverstock’s nearest hospital, Wellington Hospital, is about 0.9 miles south-west. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. London plant rooms are often on roofs or in basements reached through occupied floors.
If you run a surgery, dental practice or care home near Haverstock, clean ventilation matters as much to you as to a hospital like Wellington Hospital (about 0.9 miles south-west). If you manage offices or shops near South Hampstead station, their ventilation can be inspected and cleaned out of hours. For schools like Fine Arts College, the holidays are the usual time to inspect and clean ventilation.

Honest limits
Before booking, it helps to know what’s not included:
- Building management system faults

- Coils that are corroded or leaking and need replacing
If in doubt, call us on 0345 646 2711 or email us and we’ll say what we think.
Parts of the system we cover
- Supply and extract fans
- Heating and cooling coils
- Drain trays
- Filter sections
- Internal panels
- Dampers and louvres
Between visits
To keep the system working properly between visits:
- Keep the area around the fresh air intake clear
- Plan the next inspection before the last report gets filed away
- Do not ignore odours coming through the grilles
- Keep inspection doors on the unit in good order
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
