AHU cleaning in St Giles, done properly
Our AHU cleans for sites in St Giles cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. The work covers supply and extract fans, heating and cooling coils and dampers and louvres, and the jobs we see most are air handling units due a clean after building work and intake sections clogged with outdoor debris.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in St Giles, dust settles in the units and ducts year after year.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What your team can do, and what needs us
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
What affects the quote in St Giles
Your quote is based on your site. We consider:
- The condition of the system
- Whether it’s a one-off visit or part of a schedule
- The scale of the work
- Parking and loading at the site
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
What to send for a quote
You don’t need the technical terms. Just send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any symptoms, from odd noises to smells or leaks
- Detail shots of panels, filters and grilles
- A few general shots of the system
If you need AHU cleaning in St Giles, phone us on 0345 646 2711 or send us an email. Tell us what kind of premises it is and when it’s open, and send pictures or your last report if you can. A fixed quote typically follows within one working day.
Common problems we fix in St Giles
Whatever surrounds a building in St Giles, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and the finer material travels on.
Any of these means the system needs a check-up:
- Dirty filters cutting the airflow
- Air handling units due a clean after building work
- Rooms that smell stuffy when the system runs
- Leaves and litter drawn into the unit
If you run an office near Tottenham Court Road station, its supply ductwork can gather dust for years before anyone looks inside.
What your quote should include
- Whether the price is fixed
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether VAT is included
- Whether they’re fully insured

What else we do in St Giles
St Giles buildings and their air
Food Standards Agency records list about 81 schools, colleges and universities, about 48 caring premises (care homes, nurseries and hospitals) and about 236 hotels and guest houses registered as food businesses within roughly a mile and a half of the centre of St Giles. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. For St Giles, the closest hospital is St Paul's Hospital, roughly within half a mile east. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. Ventilation cleaning in London buildings is usually planned for evenings or weekends.
For schools like St Josephs Catholic Primary School, the holidays are the usual time to inspect and clean ventilation. If you run a surgery, dental practice or care home near St Giles, clean ventilation matters as much to you as to a hospital like St Paul's Hospital (about within half a mile east).

Between visits
Results last longer with the right care. We suggest:
- Don’t store bins or materials near the intake
- Keep inspection doors on the unit in good order
- Plan the next inspection before the last report gets filed away
- Report musty smells from the vents right away
Stick to the filter change schedule, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
When something else is needed
In fairness, some problems need a different fix:
- Faulty motors, drives or bearings
- The supply and extract ducts, quoted separately
- Ventilation that was badly designed in the first place
If in doubt, phone us on 0345 646 2711 or email us and we will say what we think.

St Giles questions
Do you do school ventilation cleaning in St Giles in the summer holidays?
Yes. The holidays are the usual time for school work. There are about 81 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of St Giles. Booking early in the term gives the best choice of holiday dates.
Do you work at weekends in St Giles?
Yes, we can come after you close and finish before you open. It means the site in St Giles keeps running as normal. Your opening times are the first thing we ask for.
How far ahead should we book?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
How often should an air handling unit be cleaned?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and we’ll suggest an interval after the first clean.
What should I send you?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then phone us on 0345 646 2711 or use the quote form.
How long will the unit be out of action?
It takes anything from half a day for one small unit to several shifts for a plant room full of them. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
Do you clean the ductwork as well?
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.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Multi-site and managed buildings
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
The process
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site 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. Most London sites can’t stop for the day, so work in St Giles is typically done overnight, early in the morning or at weekends.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Before we arrive
- Name a contact who can let us in at the agreed time
- Dig out any earlier paperwork for the system
- Move anything stored near the system
How to get a quote
Getting a quote does not take long. Send a few details and photos, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
