Common questions in Calcot
Can you work in Calcot outside opening hours?
Yes, out-of-hours work is a big part of what we do. The work in Calcot can fit around your hours. Tell us your opening hours when you ask for a quote.
Can ventilation in schools around Calcot be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. There are about 11 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Calcot. Booking early in the term gives the best choice of holiday dates.
What do you do to protect the area?
By covering it before any work starts. The work is kept contained and clean down when we finish.
Can you quote from pictures?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
What accreditations do you have?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Do you need to switch the unit off?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
AHU cleaning in Calcot, done properly
We clean air handling units for buildings in Calcot and across West Berkshire, working to TR19® Air, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers filter sections, supply and extract fans and internal panels, and people most often call us about condensate trays that won’t empty and odours coming through the supply air.
In a place like Calcot, air handling units are often tucked into roof spaces or small plant rooms, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.
The paperwork matters as much as the work. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

AHU cleaning around Calcot
The FSA’s food hygiene register lists about 11 schools, colleges and universities and about 15 hospitals, care homes and childcare premises with registered kitchens or food service in Calcot and the streets around it, up to about 1.5 miles out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Battle Hospital is the nearest hospital, about 2.5 miles north-east of Calcot. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. About 41 miles out from central London, Calcot is part of the South East area we work across. Evening, overnight and weekend visits are all possible.
Classrooms and halls at schools such as Calcot Infant School and Nursery are easiest to work in when pupils are away.

Honest limits
We’d rather tell you now than book work that will not help, so these are the things it won’t cover:
- Airflow problems caused by the system’s design
- Coils that are corroded or leaking and need replacing
- The supply and extract ducts, quoted separately
If in doubt, phone us on 0345 646 2711, or email photos and we will say what we think before you book.
Parts of the system we cover
- Supply and extract fans
- Filter sections
- Internal panels
- Drain trays
- Heating and cooling coils
- Dampers and louvres
In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Managing agents and facilities teams in Calcot
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.

Aftercare tips
To keep the system working properly between visits:
- Do not ignore odours coming through the grilles
- Note any water around the unit or leaks below it
- Look at the condensate drain whenever the unit is serviced
- Book the next check in line with the report
The report suggests a date for the next inspection or clean, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
What affects the quote in Calcot
Every site gets its own quote. This is what makes a difference:
- How many systems or sites are involved
- When the work can happen, such as evenings, overnight or weekends
- A single visit or a regular plan
- Travel, parking and unloading
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before we start.
What to send for a quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- The site address and the type of premises
- Photos showing the whole system and its surroundings
- Any previous report or certificate
- The times we could work without disrupting the site
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
How the visit works
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes one overnight shift for many single units, with bigger plant phased. Getting to the system matters more than parking in a place like Calcot, so let us know how to reach it.
- 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.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Have your last certificate or report to hand
- Mention any sign-in, permit or induction we need
- Move anything stored near the system
