AHU cleaning in West Twyford
Our AHU cleaning covers sites in West Twyford and the rest of Greater London, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers heating and cooling coils, internal panels and supply and extract fans, and people most often call us about dirty fans and fan housings and coils clogged with dust and debris.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in West Twyford is typically planned out of hours. Parking and loading are agreed with the building in advance.
Good records are part of the job. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

How it works
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes from a few hours for a compact unit to a day or more for a large one, and the area is cleaned down before we leave. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in West Twyford.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after pictures.
Getting ready for the visit
- Let us know about permits to work or site inductions
- Mention any parking or loading restrictions
- Find the previous report, if there is one

Keeping the system healthy
Aftercare is simple, and it makes the next visit easier:
- Plan the next inspection before the last report gets filed away
- Report water on the plant room floor
- Do not ignore odours coming through the grilles
- Make sure the unit’s access doors open easily
Restart the unit with your site team or maintenance contractor once we’ve finished. Check the drain tray is emptying over the first few days to confirm water is draining away.
Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
What the work involves, part by part
Drain trays
Drain trays can rust and leak over time. We record their condition with photos so repairs can be planned.
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
Why act early in West Twyford
If people in a building in West Twyford complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. For a site in West Twyford, fitting the work in overnight now is far easier than closing at short notice later.
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, give us a ring on 0345 646 2711, or email photos and we will give you an honest view and a fixed quote.

Fixed quotes for AHU cleaning in West Twyford
You will get a fixed price before work begins. It’s based on:
- How easy every part is to reach
- Whether several sites go on one quote
- The times the site is available
- The size of the system
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, give us a ring on 0345 646 2711 or use the quote form, and we’ll explain what it covers.
Helping us quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Your opening hours and when the area is out of use
- Any access panels or hatches you can see
- How we’d reach plant on a roof or in a plant room
- Photos showing the whole system and its surroundings
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.

West Twyford: your questions answered
Do you work overnight in West Twyford?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Let us know the hours you’re closed and we’ll book within them.
Does London parking affect a job in West Twyford?
London parking can be tight, so details of loading bays and permits help. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
Can you come out in an emergency?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’re fully insured and have been trading since 2009.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and we will quote them together.
Are you insured?
Yes. We carry full insurance and have been trading since 2009.
What do you do to protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
