What happens if it’s left?

AHU cleaning in Tower Hamlets, done properly
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. If you’re dealing with air handling units due a clean after building work and debris and leaves in the fresh air intake, we can put it right, from dampers and louvres, heating and cooling coils and drain trays onwards.
In a smaller place like Tower Hamlets, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Smaller systems still gather dust and need inspecting.
For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Different parts, different methods
Drain trays
The drain tray collects water from the cooling coil. Standing water and slime are removed and the outlet is checked.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey, before we quote.
What we do, step by step
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes from a few hours for a compact unit to a day or more for a large one. Everything the job in Tower Hamlets needs is worked out beforehand, from the survey.
- We survey the unit from photos or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Before we arrive
- Move anything stored near the system
- Let us know how we reach the system, including roofs, risers and plant rooms
- Name a contact who can let us in at the agreed time
How to get a quote
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 pictures, get a survey first. Either way, you get a fixed price before we start.

Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Keep the certificate and photo report with the plant records
- Do not ignore odours coming through the grilles
- Report stiff or damaged access doors
- Diary the inspection date recommended in the report
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
Fixed quotes for AHU cleaning in Tower Hamlets
You’ll get a fixed price before we start. It takes into account:
- How easy every part is to reach
- Whether several sites go on one quote
- Site rules, permits and inductions
- Whether it’s a one-off visit or part of a schedule
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.
Helping us quote
When you call or email, these details help:
- The times we could work without disrupting the site
- How we’d reach plant on a roof or in a plant room
- The site address and the type of premises
- Detail shots of panels, filters and grilles
Getting a quote doesn’t take long. Call or email with a few details and you’ll typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Ventilation in Tower Hamlets buildings
The FSA’s food hygiene register lists about 11 schools, colleges and universities, about 21 caring premises (care homes, nurseries and hospitals) and about 8 hotels and B&Bs with registered kitchens or food service in Tower Hamlets and the streets around it, up to about 1.5 miles out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Royal Victoria Hospital is the nearest hospital, about within half a mile east of Tower Hamlets. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Classrooms and halls at schools such as Priory Fields School are easiest to work in when pupils are away. If you run a surgery, dental practice or care home near Tower Hamlets, clean ventilation matters as much to you as to a hospital like Royal Victoria Hospital (about within half a mile east).

Questions from Tower Hamlets
Do you work at weekends in Tower Hamlets?
Yes, out-of-hours work is a big part of what we do. The work in Tower Hamlets can fit around your hours. Your opening times are the first thing we ask for.
Can you get to a site in Tower Hamlets?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Will you repair the fan or motor?
The clean includes noting faults, but repairs sit with your maintenance contractor, with pictures where it helps.
What information do you need?
A short description and a few photos, with the address and opening hours. We’ll ask for anything else we need.
Can you price the work without visiting?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
How do you keep the site clean during the work?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, and new panels can be fitted.
What we’re called out for in Tower Hamlets
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Look out for any of the following:
- Air handling units never cleaned inside
- Dust built up on fan impellers
- Debris and leaves in the fresh air intake
- Units needing a clean before a new tenant or handover
For workplaces around Dover Priory station with mechanical ventilation, cleaning can be done in the evening or at weekends.
What your quote should include
- Which accreditations they hold, and whether you can check them
- Whether the quote is based on a survey or pictures
- Whether VAT is included
- Whether the figure could change on the day
Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
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. Leave those to us.
