UK-Based Specialists in Contractual Cleaning
APT ICC provides contractual cleaning services across England and Wales, working as a principal contractor or specialist sub-contractor to deliver defined cleaning scopes as part of larger construction, refurbishment, and specialist works projects. Contractual cleaning differs from routine or maintenance cleaning, as it involves a clearly defined set of works delivered from start to completion under an agreed contract.
This type of service is often referred to as project cleaning, contract works cleaning, or specialist cleaning contracts. While the terminology may vary, the purpose remains the same: to complete a specific cleaning package within a wider project, aligned to programme requirements, site conditions, and technical specifications.
APT ICC delivers contractual cleaning across hospitals, universities, industrial facilities, commercial buildings, and construction sites. Works may include specialist surface cleaning, roof and gutter cleaning, lead paint removal, façade cleaning, and post-works cleaning prior to handover. Each contract is assessed in detail to ensure the correct methods, resources, and sequencing are applied to meet project requirements.
Contractual cleaning is commonly required where cleaning forms a critical part of project completion, refurbishment, or compliance works. APT ICC works closely with main contractors, developers, and project managers to deliver cleaning activities safely and efficiently, coordinating with other trades and operating within live or sensitive environments where required.
With over 35 years of experience, APT ICC is trusted to deliver contractual cleaning on complex and high-value projects. Recent works include contracted cleaning services at Morriston Hospital for Lewis Construction, project-based building cleaning for Markbank with Owens Building Cleaning, lead paint removal and external works at Singleton University for John Weaver Construction, and contracted cleaning works for Senior Flexonics under Powell Construction. All services are delivered under strict health, safety, and environmental controls, ensuring reliable delivery from mobilisation through to final completion across England and Wales.
“I would like to express my sincere thanks to APT for the excellent job they carried out at Tai Bach. The project was a much needed one and now that it is completed it has really helped to improve the look of the town. We have received many good comments from the public which is always a good sign.”
Kevin Hiller - Property Surveyor, Neath & Port Talbot Council
“We employed the services of APT to renovate a Grade 2 Listed Building. Under the directive of Cadw we were not allowed to use any wet process or chemicals within the interior of the building. APT used Soda Blasting on sandstone, brick, ceramic glazed tiles, metal work, paintwork on ceilings, coving, woodwork and ornate fixtures.
It was a great achievement to have one system for all the surfaces that needed cleaning and restoring and one that also ticked all the boxes of the environmental and conservation officers. The process saved us both time & money in being able to have just one company on site. We are very grateful to APT for their hard work on this project.”
Tim Luke - Gee Construction
“I would like to thank APT-ICC for their excellent work and assistance on the Barclays Bank project. They delivered the scheme and additional works on time and without issue thanks to Andrew and his team for all your extra effort, long hours and commitment. I look forward to using them on future renovations.”
Graham Lowe - Project Manager, Overbury Plc
“We have been receiving an overwhelming number of positive comments about the war memorial cleaning. Yesterday, during the small ceremony at the Penrallt column on the 1st World War anniversary, many expressed their appreciation for how splendid the memorial looks after the cleaning. We anticipate sharing photos on the internet page later this week. Additionally, we have shared your details with another person who serves as the clerk to two other local councils. Thank you once again for the exceptional work.”
Janice Davies - Gwynedd Council
Contractual cleaning is a fully scoped cleaning service delivered as part of a defined project. It covers specific works from start to finish rather than ongoing routine cleaning. This approach is often used on refurbishment, construction, or specialist cleaning projects.
Contractual cleaning focuses on completing a fixed scope of work within a set programme. Regular contract cleaning is usually ongoing maintenance. Contractual cleaning is planned, scheduled, and coordinated with other trades on site.
Contractual cleaning is typically used when the work is too large, complex, or time-sensitive for in-house teams. This includes project handovers, refurbishment works, or specialist surface cleaning. It helps ensure consistency and accountability across the full scope.
Yes, contractual cleaning is often carried out on live industrial and commercial sites. Works are planned to minimise disruption and fit around site operations. Clear coordination helps avoid delays and conflicts with other activities.
Contractual cleaning can include specialist surface cleaning, façade cleaning, roof and gutter cleaning, post-works cleaning, and other defined tasks. The exact scope depends on the project requirements. All works are delivered to agreed specifications.
In-house teams may support certain tasks, but contractual cleaning usually requires dedicated management and specialist resources. Having a single contractor reduces coordination issues and improves overall control. This is particularly important on complex projects.
Yes, contractual cleaning is often a key part of final project handover. It ensures areas are cleaned to the required standard before inspection or occupation. This helps avoid delays at the final stages of a project.
