AHU cleaning in Foster Street, done properly
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from photos or a site visit, and send you a fixed quote before any cleaning starts. If you have drain trays holding standing water and stale or musty smells from the ventilation, we can put it right.
Somewhere as small as Foster Street, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
The paperwork matters as much as the work. You get a written report with pictures after every visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Aftercare tips
Good habits slow the build-up between visits. A few tips:
- Book the next check in line with the report
- Store the TR19 paperwork where auditors can find it
- Make sure the unit’s access doors open easily
- Keep the area around the fresh air intake clear
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
Part by part
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
Foster Street buildings and their air
Food Standards Agency records list about 12 schools, colleges and universities, about 16 caring premises (care homes, nurseries and hospitals) and about 3 hotels and guest houses registered as food businesses in Foster Street and the streets around it, up to about 1.5 miles out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About 3 miles west of Foster Street is Princess Alexandra Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. About 21 miles out from central London, Foster Street is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site.
Princess Alexandra Hospital, about 3 miles west, is the nearest hospital to Foster Street, and healthcare sites of every size need their supply air kept clean.

Fixed quotes for AHU cleaning in Foster Street
We quote each job individually. This is what makes a difference:
- The times the site is available
- Any permits to work or inductions
- Access, including roofs, risers and ceiling voids
- The condition we find in the survey
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.
Asking for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- The times we could work without disrupting the site
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Problems your staff have spotted
- The site address and the type of premises
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Once you have those, give us a ring on 0345 646 2711 or email us.
Foster Street questions
Do you work at weekends in Foster Street?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.
Can a school’s ventilation in Foster Street be done out of term time?
Yes, holiday work suits schools best. Around Foster Street, the Food Standards Agency lists about 12 schools and colleges with registered kitchens within a mile and a half or so. Just ring 0345 646 2711 or use the quote form with your term dates and we will plan around them.
Can you clean the ducts connected to the AHU?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can survey both on the same visit.
What if parts of the system can’t be reached?
Anything we can’t reach goes on the report, with pictures where possible, and we explain what access is needed, for example new access panels.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Each site gets its own report and photos.
Will the ventilation be off while you clean?
Yes, while the clean is under way. Out-of-hours work is available so the building is not left without ventilation when it’s busy.
How often should an air handling unit be cleaned?
That’s set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Managing agents and facilities teams in Foster Street
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
What your team can do, and what needs us
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Signs you need AHU cleaning in Foster Street
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and that’s where slime and odours start.
Clients normally contact us after spotting one of these:
- Condensate trays that will not empty
- Units needing a clean before a new tenant or handover
- Coils clogged with dust and debris
- Intake sections clogged with outdoor debris
Wherever a school like Henry Moore Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Before booking anyone
- When the next visit should be, and why
- What happens if part of the system can’t be accessed
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Exactly which parts of the system are covered
How the visit works
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. If you can send photos, we can arrive in Foster Street knowing what to expect.
- We survey the unit from pictures or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after pictures.
Preparing for the visit
- Find the previous report, if there is one
- Let us know when the site is closed or quiet
- Make sure equipment near the work can be switched off and left to cool
