About our AHU cleaning in Lower Higham
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after photos in a report. If you have dust-coated heating and cooling coils and leaves and litter drawn into the unit, we can put it right.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Managing agents and facilities teams in Lower Higham
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
Leave it or put it right?
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, particularly where damp has made it stick. With notice, the visit to Lower Higham can be fitted around your bookings and events.
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.

What your team can do, and what needs us
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Common questions in Lower Higham
Is Lower Higham within the area you cover?
Yes. Lower Higham is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Can you clean school ventilation in Lower Higham during the holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 3 schools, colleges and universities with registered kitchens within about a mile and a half of Lower Higham. Tell us your holiday dates and we’ll book the visit for when the site is empty.
What should I send you?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. Then call us on 0345 646 2711 or send us an email.
What accreditations do you have?
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.
How far ahead should we book?
The more notice, the better, especially for out-of-hours work. We normally quote within one working day, and emergencies are covered by our 24/7 line.
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.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. We keep the work contained and clean down when we finish.
What do you do with what you remove?
It leaves the site with us when we go. During the work, it’s contained so the area stays clean.
Ventilation in Lower Higham buildings
The FSA’s food hygiene register lists about 3 schools, colleges and universities with registered kitchens or food service across Lower Higham and its immediate surroundings (about a mile and a half). Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Lower Higham, about 25 miles from central London, is within our usual area. A survey and a fixed quote come first, then the visit at a time that suits you. French Hospital is the nearest hospital, about 3.3 miles south-east of Lower Higham. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
For schools like Higham Primary School, the holidays are the usual time to inspect and clean ventilation. Workplaces around Higham station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. Healthcare buildings such as French Hospital, about 3.3 miles south-east, depend on their ventilation; if you manage a surgery, clinic or care home near Lower Higham, yours matters too.
Lower Higham is about 3 miles north-west of Rochester, in Medway.

Other landmarks nearby include French Hospital (3.3 miles south-east) and Upnor Castle (3.1 miles south-east). Open spaces near Lower Higham include Gad's Hill and Rede Common.
Looking after it afterwards
Simple habits between visits make a real difference. We recommend:
- Make sure condensate is draining away
- Keep the area around the fresh air intake clear
- File each AHU report in the maintenance log
- Report stiff or damaged access doors
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.

Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey, before we quote.
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
