About our AHU cleaning in Lamb Corner
Our AHU cleans for sites in Lamb Corner cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. The work covers internal panels, filter sections and dampers and louvres, and common reasons people get in touch are leaves and litter drawn into the unit and dirty fans and fan housings.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Evening, overnight and weekend visits are all possible. The nearest hospital to Lamb Corner is Severalls Hospital, about 4 miles south-west. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.

Near you in Lamb Corner

What we’re called out for in Lamb Corner
Filters that are not changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
Any of these means the system needs a check-up:
- Air handling units with blocked filters
- Debris and leaves in the fresh air intake
- Plant that needs cleaning after a refit
- Odours coming through the supply air
Hospitals such as Severalls Hospital (about 4 miles south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Lamb Corner are no different.

What AHU cleaning cannot fix

- Damaged coils beyond cleaning
- Building management system faults

What we work on in Lamb Corner
- Supply and extract fans
- Filter sections
- Dampers and louvres
- Heating and cooling coils
- Drain trays
- Internal panels
How the job changes from site to site
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
Internal casing and panels
Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.
Lamb Corner questions
Can you get to a site in Lamb Corner?
Yes, we work in villages as well as towns, and Lamb Corner is covered. Let us know about access, parking and anything unusual about getting there when you book.
Do you clean school ventilation in Lamb Corner in the holidays?
Yes, out-of-term visits are normal for schools. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Lamb Corner, it pays to plan holiday dates ahead. You can call us on 0345 646 2711, or send details by email with the dates the site is empty.
Is there a survey before the work?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Are you insured?
Yes. We carry full insurance and have been trading since 2009.
Will you repair the fan or motor?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.
What happens if you cannot reach some of it?
The report shows them clearly. In ductwork, new access panels are often the answer, which we can install.
Can you quote from pictures?
Yes, where the pictures show enough. If not, a site survey comes first, then a fixed quote.
How much notice do you need?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
How it works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before we start, and floors and nearby surfaces are sheeted. On site, it takes half a day to a full day per unit, with large plant planned over several shifts. Somewhere as small as Lamb Corner, the date and timings are agreed with you well before the day.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Getting ready for the visit
- Let us know about parking and loading
- Agree a time when the area can be out of use
- Have your last certificate or report to hand
How to get a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
Related advice
What happens if it’s left?
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. That makes the next inspection of a building in Lamb Corner simpler. Rural sites cannot always move to another kitchen or room when something fails.
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711, or send details by email, and we’ll talk you through it.

Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Flag stale or damp smells in the supply air
- Stick to the filter change plan
- Look at the condensate drain whenever the unit is serviced
- Clear leaves and litter away from the intake
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
