Managing agents and facilities teams in Brock Hill
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
AHU cleaning for kitchens and businesses in Brock Hill
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. The work covers supply and extract fans, filter sections and internal panels, and people most often call us about dust-coated heating and cooling coils and plant that has been serviced but not cleaned.
For a building in or near Brock Hill, access is agreed in advance and the visit is planned around the journey.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What affects the cost of AHU cleaning
Every site gets its own quote. These are the things that affect it:
- Whether several sites go on one quote
- Any permits to work or inductions
- A single visit or a regular plan
- How easy every part is to reach
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and why the quote is fixed before any work starts.
What we need to know
To speed up the quote, send us:
- When the site is open and when it’s quiet
- Detail shots of panels, filters and grilles
- Any symptoms, from odd noises to smells or leaks
- Any previous report or certificate
Quotes are quick. Send a few details and photos, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
What AHU cleaning looks like in Brock Hill
Food Standards Agency data includes about 6 schools, colleges and universities and about 6 caring premises (care homes, nurseries and hospitals) within 1.5 miles or so of the middle of Brock Hill. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Brock Hill’s nearest hospital, Mayflower Community Hospital, is about 4.6 miles west. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. Brock Hill is about 28 miles from central London, well within the area we cover across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.

What else we do in Brock Hill
What a clean won’t put right
AHU cleaning cannot fix everything, and we will tell you before we start. It does not solve:
- Coils that are corroded or leaking and need replacing
- Ventilation that was badly designed in the first place
- Breakdowns that need a mechanical engineer
If you are not sure, just call us on 0345 646 2711, or send details by email and we will give you a straight answer before you book.
Parts of the system we cover

How the visit works
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, do the work, tidy up and leave you the report. The visit itself 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 Brock Hill knowing what to expect.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Have your last certificate or report to hand
- Make sure equipment near the work can be switched off and left to cool
- Mention any parking or loading restrictions
Getting a quote
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and the last certificate or report, if there is one. Then ring 0345 646 2711, or send details by email.

How the job changes from site to site
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe with your site team.
What happens if it’s left?
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. Systems in rural buildings are often out of sight and out of mind.
We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.

What we’re called out for in Brock Hill
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. Months can pass without anyone looking inside.
Common reasons sites call us are:
- Dust built up on fan impellers
- Dust-coated heating and cooling coils
- Air handling units never cleaned inside
- Rooms that smell stuffy when the system runs
Hospitals such as Mayflower Community Hospital (about 4.6 miles west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Brock Hill are no different.
