How the job changes from site to site
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that will not bend or flatten the fins.
AHU cleaning in Batchworth, done properly
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 pictures or on site, followed by a fixed quote, so you know where you stand. If you have air handling units due a clean after building work and debris and leaves in the fresh air intake, we can help.
In a village or hamlet like Batchworth, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Staff cleaning versus specialist work
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
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 will take a look and give you a fixed quote.
Fixed quotes for AHU cleaning in Batchworth
Your quote is based on your site. We take into account:
- The times the site is available
- Site rules, permits and inductions
- Whether it’s a one-off visit or part of a schedule
- The condition of the system
What you pay reflects the actual work. That’s why every job is surveyed first, and the price is agreed before any work starts.
What we need to know
Before you ask for a quote, gather:
- The roof, plant room or outside wall the system runs to
- Detail shots of panels, filters and grilles
- Any symptoms, from odd noises to smells or leaks
- The paperwork from the last visit, if you have it
To get a fixed quote, call us on 0345 646 2711 or send us an email and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We usually come back within one working day.

Ventilation in Batchworth buildings
There are about 10 schools, colleges and universities, about 13 hospitals, care homes and childcare premises and about 3 hotels and guest houses on the FSA’s food hygiene register in Batchworth 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. At about 18 miles from central London, Batchworth sits well inside the area we cover. We work evenings, overnight and at weekends, so the visit fits around the site. The nearest hospital to Batchworth is Bishops Wood Hospital, about 1.1 miles south-east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Wherever a school like St Mary's Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time. If you run an office near Rickmansworth station, its supply ductwork can gather dust for years before anyone looks inside.

How the visit works
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes from a few hours for a compact unit to a day or more for a large one. If you can send photos, we can arrive in Batchworth knowing what to expect.
- 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.
- 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
- Let us know when the site is closed or quiet
- Make sure equipment near the work can be switched off and left to cool
- Have your last certificate or report to hand

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 pictures, get a survey first. Either way, you get a fixed price before any work starts.
Related advice
Keeping the system healthy
Looking after the system between visits is straightforward, and it helps at the next visit:
- Keep inspection doors on the unit in good order
- Don’t ignore odours coming through the grilles
- Watch for drips or damp patches near the plant
- Look at the condensate drain whenever the unit is serviced
When we have closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
Common questions in Batchworth
Can you clean school ventilation in Batchworth during the holidays?
Yes, holiday work suits schools best. There are about 10 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Batchworth. Tell us your holiday dates and we will book the visit for when the site is empty.
Is Batchworth within the area you cover?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Can you come out in an emergency?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
What do you do to protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
How often should an air handling unit be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
What we’re called out for in Batchworth
Whatever surrounds a building in Batchworth, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and some travels further into the unit.
Common reasons sites call us are:
- Units that have only ever had filter changes
- Leaves and litter drawn into the unit
- Dust built up on fan impellers
- Drain trays holding standing water
If you run a surgery, dental practice or care home near Batchworth, clean ventilation matters as much to you as to a hospital like Bishops Wood Hospital (about 1.1 miles south-east).
