Kensington: your questions answered
Do you do school ventilation cleaning in Kensington in the summer holidays?
Yes, holiday work suits schools best. Around Kensington, the Food Standards Agency lists about 93 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can parking be tricky for a job in Kensington?
London parking can be tight, so details of loading bays and permits help. Working overnight, as we often do in London, typically makes it simpler.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, along with a few pictures and any previous report.
Do you give a certificate after the clean?
Yes. A TR19® certificate and photo report are sent after the clean, with any faults we noticed.
Do you need to switch the unit off?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
What if parts of the system cannot be reached?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, along with a quote to put access in.
Can one contract cover all our sites?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
About our AHU cleaning in Kensington
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from pictures or on site, followed by a fixed quote, so you know where you stand. If you have odours coming through the supply air and debris and leaves in the fresh air intake, we can help, from internal panels, drain trays and dampers and louvres onwards.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Kensington is typically planned out of hours. Parking and loading are agreed with the building in advance.
Each visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Between visits
No system stays clean for ever, but care slows the build-up. Our tips:
- File each AHU report in the maintenance log
- Book the next check in line with the report
- Change filters on schedule and log each change
- Make sure condensate is draining away
When we’ve closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
How the visit works
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, do the work, tidy up and leave you the report. On site, the work takes one overnight shift for many single units, with bigger plant phased. Security desks and permits-to-work are routine in London, so let us know what your building in Kensington needs from us.
- We start with a survey of the unit and a fixed quote for the work.
- 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.
Preparing for the visit
- Allow time for equipment near the work to be turned off and cool down
- Move anything stored near the system
- Dig out any earlier paperwork for the system
Ask for a quote
Quotes are quick. Call or email with a few details and you will normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

What affects the cost of AHU cleaning
The survey tells us what the work involves. We look at:
- Site requirements such as sign-in and permits
- When the work can happen, such as evenings, overnight or weekends
- Where the site is and how we reach it
- How easy every part is to reach
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
Asking for a quote
When you contact us, these details help:
- How we’d reach plant on a roof or in a plant room
- The times we could work without disrupting the site
- Any previous report or certificate
- Wide pictures of the system and the area around it
Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and the last certificate or report, if there is one. Once you have those, give us a ring on 0345 646 2711 or drop us a line.
AHU cleaning around Kensington
Food Standards Agency data includes about 93 schools, colleges and universities, about 66 caring premises (care homes, nurseries and hospitals) and about 138 hotels and B&Bs in and around Kensington, up to about a mile and a half out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Getting kit to a London plant room normally means lifts, stairs and an agreed loading slot. The nearest hospital to Kensington is St Mary Abbot's Hospital, about 0.5 miles east. 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 Mary Abbot's Hospital (about 0.5 miles east) to small clinics, depends on clean filters, coils and ducts. If you manage a school such as St Barnabas and St Philip's CofE Primary School, ventilation cleaning is best booked for the holidays. If you run an office near Kensington Olympia station, its supply ductwork can gather dust for years before anyone looks inside.

What a clean won’t put right
We’d rather tell you now than book work that won’t help, so here are the limits:
- Breakdowns that need a mechanical engineer
- Ductwork downstream of the unit, which is a separate clean
- Damaged coils beyond cleaning
If in doubt, phone us on 0345 646 2711, or send details by email and we will say what we think before booking.
Parts of the system we cover
- Drain trays
- Supply and extract fans
- Heating and cooling coils
- Internal panels
- Filter sections
- Dampers and louvres
What happens if it’s left?
If people in a building in Kensington complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. Leaving it on a busy London site only adds to the work.
We don’t list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.
