UK-Based Specialists in Confined Space Cleaning
APT ICC provides specialist confined space cleaning services across England and Wales, supporting organisations that require safe and controlled cleaning within enclosed or restricted environments. Confined space cleaning involves entering low- and medium-risk confined spaces to remove contamination that cannot be accessed or cleaned from outside.
The service is sometimes referred to as confined space entry cleaning or enclosed space cleaning. While the wording may differ, the purpose remains the same: to safely clean areas where access is limited and hazards are
more likely to be present. These environments can include pits, tanks, silos, ducts, ovens, sumps, and other enclosed structures used within industrial and manufacturing settings.
APT ICC cleans a wide range of confined spaces, from machine pits and sumps to large industrial ovens and internal tanks. Cleaning works may involve the removal of oil, grease, dust, swarf, coolant, waste run-off, and other build-up that can affect safety, hygiene, or equipment performance. Each confined space is assessed individually to determine the safest and most effective cleaning approach.
Safety is central to all confined space cleaning operations. Works are carried out with continuous gas monitoring, clearly defined entry and escape procedures, and trained personnel in support roles such as banksmen at
all times. This ensures cleaning can be completed safely, even in environments
with increased risk.
With over 35 years of experience, APT ICC is trusted to deliver confined space cleaning in complex and sensitive
environments. Recent projects include Klansman pit cleaning at Blaenavon
Forgings, internal silo cleaning at Abingdon Carpets involving the removal of excess resin, and cleaning works inside tile ovens for Marshalls and Marley to remove dust and material deposits. All services are delivered under strict health, safety, and environmental controls, providing reliable, high-quality results across England and Wales.
“APT did a fantastic job cleaning our warehouse. Their team was efficient and thorough, leaving the space spotlessly clean. Highly recommended!”

Lance Wilmott – Health & Safety Manager, Mayphil
“Another great job completed on the Joe Calzaghe Bridge, it looks as good as new! Thank you to all the team in managing the job with this very difficult structure.”
Veronica Tsak – Structures & Highways, Caerphilly Borough Council
Confined space cleaning involves cleaning enclosed or restricted areas that cannot be safely accessed or cleaned from outside. These spaces often contain build-up that affects safety, hygiene, or operations. Common examples include pits, tanks, silos, ducts, and sumps.
Some confined spaces can be partially cleaned from outside using specialist tools or flushing methods. However, when build-up is heavy or access is limited, safe entry is often required to fully remove contamination. This is where trained confined space teams are needed.
Confined spaces can be high-risk if not properly managed. Hazards may include poor air quality, restricted movement, or hidden residues. Professional cleaning involves planning, monitoring, and controlled entry to reduce these risks.
Small or low-risk tasks may be handled in-house if the correct training and controls are in place. For deeper, more complex, or hazardous spaces, specialist equipment and experience are usually required. Poor planning can quickly increase safety risks.
Confined space cleaning can remove dust, grease, oil, sludge, resin, swarf, and other waste materials. This build-up can restrict access, affect equipment performance, or create safety issues if left untreated. Cleaning prepares the space for inspection or maintenance.
It can if not carefully planned. Professional cleaning is usually scheduled to minimise disruption and fit around site operations where possible. Clear planning helps reduce delays and keeps work controlled.
A specialist should be used when access is restricted, hazards are present, or results need to be consistent and documented. Confined spaces are not forgiving environments, and experience plays a major role in safety and efficiency. This is especially important on live industrial sites.
Yes. In some cases, the right cleaning chemicals can reduce the need for heavy manual cleaning or repeated entry. APT ICC can advise on suitable professional-grade products, including those manufactured by APT Commercial Chemicals, which we use across industrial sites in England and Wales.
