About our AHU cleaning in Aldwych
Our AHU cleaning covers sites in Aldwych and the rest of Greater London, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. We are often asked to deal with units that have only ever had filter changes and dirty fans and fan housings, across drain trays, supply and extract fans and filter sections.
London buildings tend to keep their plant on the roof or below ground, so work in Aldwych is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
A written report with pictures follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Looking after it afterwards
A little care between visits keeps the system in better shape. We recommend:
- Clear leaves and litter away from the intake
- Report stiff or damaged access doors
- Don’t ignore odours coming through the grilles
- Make sure condensate is draining away
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.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
What AHU cleaning looks like in Aldwych
Food Standards Agency data includes about 95 schools, colleges and universities, about 60 care, childcare and hospital premises and about 234 hotels and guest houses in Aldwych and the streets around it, up to about 1.5 miles out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. About within half a mile north of Aldwych is St Philip's Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
Healthcare ventilation, from large hospitals like St Philip's Hospital (about under half a mile north) to small clinics, depends on clean filters, coils and ducts. For schools like St Clement Danes CofE Primary School, the holidays are the usual time to inspect and clean ventilation. Workplaces around London Charing Cross station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.

Fixed quotes for AHU cleaning in Aldwych
We don’t publish a price list, because sites vary so much. The quote depends on:
- How many systems or sites are involved
- What state the system is in
- How big the system is
- Any permits to work or inductions
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
Asking for a quote
When you call or email, these details help:
- Your last certificate, test record or report
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Where the site is and what kind of site it is
- Your opening hours and when the area is out of use
For AHU cleaning in Aldwych, call us on 0345 646 2711, or send details by email. Tell us what kind of premises it is and when it’s open, plus photos or the previous report if they’re to hand. A fixed quote usually follows within one working day.
Part by part
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
What we do, step by step
Before we leave, we walk the area with whoever is on site. 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 one overnight shift for many single units, with bigger plant phased. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Aldwych.
- We agree a shutdown window that suits the building.
- We take before photos 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
- Mention any parking or loading restrictions
- Find the previous report, if there is one
- Clear the space around the work

Advice
Aldwych questions
Can you clean school ventilation in Aldwych during the holidays?
Yes. The holidays are the usual time for school work. There are about 95 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Aldwych. You can phone us on 0345 646 2711 or drop us a line with the dates the site is empty.
Do you work at weekends in Aldwych?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. When you call us on 0345 646 2711 or email us, mention when the site is quiet.
Do you repair air handling units?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report for your maintenance team to follow up.
What information do you need?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. After that, simply call 0345 646 2711 or email us.
Do you give a certificate after the clean?
Yes. You get a TR19® certificate plus before and after photos. They’re worth keeping with the plant records.
Do you have insurance?
Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.
Do you work in Aldwych?
Yes. We work in Aldwych and across Greater London, within our South East and London area. To book, give us a ring on 0345 646 2711 or drop us a line.
How long does an AHU clean take?
Expect it to take half a day to a full day per unit, with large plant planned over several shifts. Size, layout and how dirty it is decide the rest, and we will confirm the time when we quote.

What else we do in Aldwych
Managing agents and facilities teams in Aldwych
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.
Why deal with it now?
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, call us on 0345 646 2711 or send us an email and we will give you an honest view and a fixed quote.
