AHU cleaning in Pig Street
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. We are often asked to deal with dirty coils holding back the airflow and stale or musty smells from the ventilation, on filter sections, internal panels and drain trays.
For a building in or near Pig Street, access is agreed in advance and the visit is planned around the journey.
The paperwork matters as much as the work. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

AHU cleaning in Pig Street: local notes
Food Standards Agency data includes about 6 hospitals, care homes and childcare premises in and around Pig Street, up to about a mile and a half out. Busy, occupied buildings like these are where clean supply air matters most. About 59 miles out from central London, Pig Street is part of the South East area we work across. The visit is fixed around your opening hours, not ours.
School buildings such as Rolph CofE Primary School are typically done in the holidays, so classrooms aren’t disturbed.

What happens on the day
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. The middle part takes longest, which takes half a day to a full day per unit, with large plant planned over several shifts. Photos of the system and how to reach it help us plan a visit to Pig Street.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Preparing for the visit
- Have your last certificate or report to hand
- Name a contact who can let us in at the agreed time
- Let us know about permits to work or site inductions
Ask for a quote
Getting a quote doesn’t take long. Send a few details and photos, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

Common problems we fix in Pig Street
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Pig Street, that’s air they breathe for hours at a time.
Clients normally contact us after spotting something like this:
- Dirty filters cutting the airflow
- Stale or musty smells from the ventilation
- Air handling units due a clean after building work
- Coils clogged with dust and debris
If you run an office near Thorpe-Le-Soken station, its supply ductwork can gather dust for years before anyone looks inside.
Questions to ask before booking

- Proof of insurance
- What records you’ll receive afterwards
- Whether the price is fixed
How the job changes from site to site
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.
Filters
Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and the housing around them is cleaned too.
Aftercare tips
Good habits slow the build-up between visits. A few tips:
- Clear leaves and litter away from the intake
- Diary the inspection date recommended in the report
- File each AHU report in the maintenance log
- Make sure the unit’s access doors open easily
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
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.

FAQs for Pig Street
Do you offer AHU cleaning in Pig Street?
Yes, we work in Pig Street and the places around it. A fixed quote typically follows within one working day of the survey details.
Is Pig Street within the area you cover?
Yes. Pig Street is within the area we cover across London and the South East. A survey first, from pictures or a visit, means we arrive with the right kit.
Does the AHU have to be shut down for cleaning?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
Which parts of an air handling unit do you clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
Can you look after several sites?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We have been trading since 2009 and we’re fully insured.
Staff cleaning versus specialist work
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.
When something else is needed
Some problems need a different service or another trade:
- Airflow problems caused by the system’s design
- Breakdowns that need a mechanical engineer
- Damaged coils beyond cleaning
If in doubt, ring 0345 646 2711 or email us and we’ll say what we think before you book.
Parts of the system we cover
- Internal panels
- Heating and cooling coils
- Supply and extract fans

For landlords and multi-site operators
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
