Fixed quotes for AHU cleaning in Belgravia
Every site gets its own quote. These are the things that affect it:
- One-off work versus a regular cycle
- Site requirements such as sign-in and permits
- The condition of the system
- The size of the system
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before we start.
What to send for a quote
When you contact us, these details help:
- Any symptoms, from odd noises to smells or leaks
- The roof, plant room or outside wall the system runs to
- Wide pictures of the system and the area around it
- The postcode and the type of business
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
AHU cleaning in Belgravia
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. If you have filters that are clogged or overdue and stale or musty smells from the ventilation, we can help, from filter sections, drain trays and heating and cooling coils onwards.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Belgravia is usually planned out of hours. Loading and parking are planned with the building first.
The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

AHU cleaning in Belgravia: local notes
Going by the FSA’s register, there are about 60 schools, colleges and universities, about 17 hospitals, care homes and childcare premises and about 172 hotels and guest houses serving food across Belgravia and its immediate surroundings (about a mile and a half). Busy, occupied buildings like these are where clean supply air matters most. London plant rooms are often on roofs or in basements reached through occupied floors. Belgravia’s nearest hospital, London Lock Hospital, is about within half a mile north-east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Healthcare ventilation, from large hospitals like London Lock Hospital (about within half a mile north-east) to small clinics, depends on clean filters, coils and ducts. Workplaces around London Victoria station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.

Common questions in Belgravia
How do you handle parking and loading in Belgravia?
London parking can be tight, so details of loading bays and permits help. Much of our London work is done overnight, which helps.
Do you clean school ventilation in Belgravia in the holidays?
Yes, and it’s the easiest time to do it. Around Belgravia, the Food Standards Agency lists about 60 schools and colleges with registered kitchens within a mile and a half or so. Just call 0345 646 2711, or send details by email with your term dates and we’ll plan around them.
How much does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we’ll typically reply within one working day.
Can you come out in an emergency?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we’ll advise on what to do next.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
What should I send you?
Where the site is, what it is and when it’s open, plus pictures of the system and your last certificate or report if you have one.
Can you fix a faulty AHU?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We’ll flag anything we notice during the clean.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, and any sections we can’t reach are noted in the report, and new panels can be fitted.

Multi-site and managed buildings
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.

What we are called out for in Belgravia
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
Keep an eye out for any of the following:
- Units needing a clean before a new tenant or handover
- Stale or musty smells from the ventilation
- Dust built up on fan impellers
- Debris and leaves in the fresh air intake
School buildings such as Holy Trinity CofE Primary School are usually done in the holidays, so classrooms aren’t disturbed.
Questions to ask before booking
- How VAT is shown on the quote
- Whether they recommend a next date
- What hours they’ll be on site
- If the quote is a fixed price or an estimate
Staff cleaning versus specialist work
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Looking after it afterwards
Once we have finished, these simple steps help:
- Store the TR19 paperwork where auditors can find it
- Keep inspection doors on the unit in good order
- Keep the area around the fresh air intake clear
- Don’t ignore odours coming through the grilles
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
How the visit works
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, do the work, clear away and leave you the report. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. If your building in Belgravia has sign-in rules, permits or key holders, mention them when you book.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Before we arrive
- Name a contact who can let us in at the agreed time
- Tell us about site rules, permits or sign-in
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
