FAQs for Locksbottom
What do you need to know about parking in Locksbottom?
A loading bay, a visitor permit or off-street space near the site in Locksbottom makes the visit easier to plan. Where restrictions apply in the day, an evening or overnight visit usually gets round them.
Can you clean school ventilation in Locksbottom during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Locksbottom, the Food Standards Agency lists about 12 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
Can you fix a faulty AHU?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report for your maintenance team to follow up.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
Do you give a certificate after the clean?
Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.
Can you clean the ducts connected to the AHU?
Yes, the ductwork, grilles and diffusers the unit serves. The survey shows whether the ducts need cleaning now.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
What information do you need?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply call us on 0345 646 2711 or email us.
AHU cleaning in Locksbottom
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after pictures in a report. The work covers dampers and louvres, heating and cooling coils and filter sections, and common reasons people get in touch are odours coming through the supply air and fan sections that haven’t been cleaned in years.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. For a building in Locksbottom, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
We have been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Locksbottom buildings and their air
There are about 12 schools, colleges and universities and about 21 caring premises (care homes, nurseries and hospitals) on the FSA’s food hygiene register in Locksbottom and the streets around it, up to about 1.5 miles out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Locksbottom’s nearest hospital, Princess Royal University Hospital, is about 0.5 miles south-west. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. Ventilation cleaning in London buildings is normally planned for evenings or weekends.
If you run a surgery, dental practice or care home near Locksbottom, clean ventilation matters as much to you as to a hospital like Princess Royal University Hospital (about 0.5 miles south-west). Classrooms and halls at schools such as Darrick Wood Infant & Nursery School are easiest to work in when pupils are away.

Aftercare tips
So the system stays in good health:
- Flag stale or damp smells in the supply air
- Report stiff or damaged access doors
- Store the TR19 paperwork where auditors can find it
- Keep filter changes on time and recorded
The report suggests a date for the next inspection or clean, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
The process
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. The work itself takes one overnight shift for many single units, with bigger plant phased. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in Locksbottom.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Have your last certificate or report to hand
- Agree a time when the area can be out of use
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 photos, get a survey first. Either way, you get a fixed price before we start.
Related advice
What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
How the job changes from site to site
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
Honest limits
To be straight with you, there are a few things this work will not fix:
- Breakdowns that need a mechanical engineer
- Ventilation that was badly designed in the first place
- Leaking heating or cooling coils
If you’re not sure, just phone us on 0345 646 2711, or send details by email and we’ll give you a straight answer.

- Whether we need access equipment or extra panels
- Travel, parking and unloading
- Working hours and out-of-hours timing
- Any permits to work or inductions
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711 or send us an email, and we will talk you through it.

Before you ask for a quote, gather:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The postcode and the type of business
