Toy's Hill buildings and their air
London plant rooms are often on roofs or in basements reached through occupied floors. The nearest hospital to Toy's Hill is Tandridge Priory, about 3.5 miles west. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
Wherever a school like Ide Hill Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time. Healthcare ventilation, from large hospitals like Tandridge Priory (about 3.5 miles west) to small clinics, depends on clean filters, coils and ducts.

How we handle AHU cleaning in Toy's Hill
No two plant rooms are the same, 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. We’re often asked to deal with air handling units never cleaned inside and intake sections clogged with outdoor debris, on filter sections, drain trays and supply and extract fans.
Many London buildings have had their ventilation extended and altered through several fit-outs, with old runs left behind that are hard to reach. An inspection first shows where cleaning is needed in a building in Toy's Hill.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

How it works
A visit follows the same order every time: protect the area, isolate whatever needs isolating, do the work, clear away and leave you the report. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. If your building in Toy's Hill has sign-in rules, permits or key holders, mention them when you book.
- We survey the unit from pictures or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- 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
- Agree a time when the area can be out of use
- Tell us about site rules, permits or sign-in
- Make sure someone can let us in and lock up afterwards

Different parts, different methods
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
How we price AHU cleaning
A fixed price needs a few facts first. We look at:
- The times the site is available
- Whether it’s a one-off visit or part of a schedule
- What state the system is in
- How big the system is
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before we start.
Asking for a quote
You do not need the technical terms. It helps if you can send:
- Close-ups of filters, grilles, hatches or access panels
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your opening hours and when the area is out of use
- The paperwork from the last visit, if you have it
For a fixed quote, call us on 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You will usually have a quote within one working day.
Managing agents and facilities teams in Toy's Hill
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
What AHU cleaning can’t fix
We’ll always give you a straight diagnosis, so here’s what AHU cleaning will not do:
- Ventilation that was badly designed in the first place
- Breakdowns that need a mechanical engineer
- Damaged coils beyond cleaning
Not sure which it is? You can call us on 0345 646 2711 or email us and we’ll tell you honestly before you book.
Where we work
- Heating and cooling coils
- Supply and extract fans
- Drain trays
- Dampers and louvres
- Internal panels
- Filter sections
Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Check the drain tray is emptying during routine visits
- Do not store bins or materials near the intake
- Store the TR19 paperwork where auditors can find it
- Watch for drips or damp patches near the plant
The report suggests a date for the next inspection or clean, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
Common questions in Toy's Hill
Can you work in Toy's Hill outside opening hours?
Yes, we can come after you close and finish before you open. That way a site in Toy's Hill doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Can you do AHU cleaning in Toy's Hill?
Yes, Toy's Hill is covered. Just call us on 0345 646 2711, or send details by email with a few details of the site.
What do you need from me for a quote?
A short description and a few photos plus the address and your hours. We’ll ask for anything else we need.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, and any sections we cannot reach are noted in the report, with new panels fitted where needed.
How long does it take to clean an air handling unit?
It takes from a few hours for a compact unit to a day or more for a large one. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. Before we leave, we tidy up and clean down.
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, and the quote follows that.
Why act early in Toy's Hill
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. Choosing the date yourself beats having a fault choose it for you.
You won’t 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 drop us a line, and we will talk you through it.
