For landlords and multi-site operators
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
AHU cleaning in Sunnymeads
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from photos or on site, followed by a fixed quote before any cleaning starts. If you have dust built up on fan impellers and odours coming through the supply air, we can help, from supply and extract fans, dampers and louvres and filter sections onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Ventilation in Sunnymeads buildings
Food Standards Agency data includes about 12 schools, colleges and universities and about 6 hospitals, care homes and childcare premises within 1.5 miles or so of the middle of Sunnymeads. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. For Sunnymeads, the closest hospital is King Edward VII Hospital, roughly 2.4 miles west. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Sunnymeads is about 20 miles from central London, well within the area we cover across London and the South East. Visits are booked around your hours, evenings and weekends included.
School buildings such as Wraysbury Primary School are normally done in the holidays, so classrooms are not disturbed. If you manage shops or offices close to Sunnymeads station, a TR19® Air inspection shows whether the ductwork needs cleaning.
Sunnymeads is about 3 miles north of Egham, in Surrey.

Local landmarks in Sunnymeads
Locally, jobs take us to businesses close to The Perserverance Public House, Arthur Jacob Nature Reserve and Churchmead School and the streets around them.

Green spaces nearby include Staines Reservoirs.
How it works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere like Sunnymeads, lanes, gates and parking are worth mentioning in advance.
- We survey the unit from photos or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Mention any locked doors, roof access or ceiling voids
- Tell us the best time to work, such as after service or at a weekend
- Name a contact who can let us in at the agreed time

What else we do in Sunnymeads
What a clean will not put right
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning won’t do:
- Mechanical faults with motors, belts or bearings
- A system that’s undersized for the building
- Leaking heating or cooling coils
If you are not sure, just call us on 0345 646 2711 or email us and we’ll give you a straight answer before you book.
Parts of the system we cover
- Drain trays
- Filter sections
- Internal panels
- Supply and extract fans
- Heating and cooling coils
- Dampers and louvres
Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Different parts, different methods
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and clean the filter housing.
Keeping the system healthy
Results last longer with the right care. We suggest:
- Report water on the plant room floor
- Do not store bins or materials near the intake
- Keep inspection doors on the unit in good order
- Keep the certificate and photo report with the plant records
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
Signs you need AHU cleaning in Sunnymeads
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and that is where slime and odours start.
Look out for these warning signs:
- Blocked condensate drains and slimy trays
- Units that have only ever had filter changes
- Plant that needs cleaning after a refit
- Air handling units with blocked filters
King Edward VII Hospital, about 2.4 miles west, is the nearest hospital to Sunnymeads, and healthcare sites of every size need their supply air kept clean.

Do you work in villages like Sunnymeads?
Yes. Villages and rural sites across the South East are part of our work, Sunnymeads included. A survey first, from photos or a visit, means we arrive with the right kit.
How often should an air handling unit be cleaned?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.

Do you offer maintenance contracts?

Which parts of an air handling unit do you clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.
What should I send you?

What’s TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
