AHU cleaning for kitchens and businesses in Bushey Heath
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with pictures, so the report shows exactly what was done. The work covers supply and extract fans, internal panels and dampers and louvres, and people most often call us about plant that needs cleaning after a refit and filters that are clogged or overdue.
Visits to a place like Bushey Heath are fitted around opening hours. The method doesn’t change: inspect first, clean, then record what was done.
Nothing is signed off by word of mouth: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Fixed quotes for AHU cleaning in Bushey Heath
A fixed price needs a few facts first. We look at:
- Where the site is and how we reach it
- The scale of the work
- When the work can happen, such as evenings, overnight or weekends
- Site rules, permits and inductions
What you pay depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before work begins, so there are no surprises.
What we need to know
Many jobs can be priced from photos and some basics. Useful things to send:
- How we’d reach plant on a roof or in a plant room
- Wide pictures of the system and the area around it
- The postcode and the type of business
- Close-ups of filters, grilles, hatches or access panels
If you need AHU cleaning in Bushey Heath, phone us on 0345 646 2711 or send us an email. Tell us what kind of premises it is and when it’s open, plus photos or the previous report if they’re to hand. We typically send a fixed quote within one working day.
How the visit works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes one overnight shift for many single units, with bigger plant phased, and the area is cleaned down before we leave. For a site near Bushey Heath, the work is booked around your opening hours, evenings and weekends included.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
How to prepare
- Name a contact who can let us in at the agreed time
- Tell us the best time to work, such as after service or at a weekend
- Let us know how we reach the system, including roofs, risers and plant rooms

Why act early in Bushey Heath
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. Light use slows the build-up but does not stop it.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
Why book with us
- Fully insured
- Every visit written up, with photos
- CHAS and SafeContractor accredited, with ISO 9001
- Fixed quotes from a survey or photos

Common questions in Bushey Heath
Do you clean school ventilation in Bushey Heath in the holidays?
Yes, holiday work suits schools best. There are about 11 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Bushey Heath. Booking early in the term gives the best choice of holiday dates.
Can you work in Bushey Heath outside opening hours?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Bushey Heath needn’t be disturbed. Your opening times are the first thing we ask for.
What should I send you?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. Then call 0345 646 2711, or send details by email.
Do you have a 24/7 line?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
How often should an air handling unit be cleaned?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and the report recommends a next date.
Where does the waste go?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
What about areas you cannot get to?
Anything we cannot reach goes on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
How much does AHU cleaning cost in Bushey Heath?
It depends on the site, so we quote each one individually. For a quote, give us a ring on 0345 646 2711, or send details by email and tell us about the site and its opening hours.
Keeping the system healthy
No system stays clean for ever, but care slows the build-up. Our tips:
- Check the drain tray is emptying during routine visits
- Report stiff or damaged access doors
- Clear leaves and litter away from the intake
- Don’t ignore odours coming through the grilles
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
Multi-site and managed buildings
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
When it’s something else
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- Building management system faults
- Mechanical faults with motors, belts or bearings
- A system that is undersized for the building
If in doubt, ring 0345 646 2711, or send details by email and we will say what we think before you book.
What the work covers
