The Considerate Constructors Scheme is a not-for-profit, independent organisation founded in 1997 by the construction industry to improve its image.

Construction sites, companies and suppliers voluntarily register with the Scheme and agree to abide by the Code of Considerate Practice, designed to encourage best practice beyond statutory requirements. For more information on the Code, please click here.

Construction Line

Constructionline is the UK’s leading procurement and supply chain management service that collects, assesses and monitors standard company information through a question set that is aligned to PAS 91, the standardised pre-qualification questionnaire developed by BSI to reduce duplication within the construction industry.


SMAS is an H&S Assessment organisation that takes great pride in professionalism, customer service and efficiency. Working with many of the major UK housebuilders, SMAS have developed experience and expertise in new-build construction, as well as dealing with many other construction organisations. As a dedicated H&S assessment company, they do not get distracted by other activities, such as H&S Training or Consultancy. 


Suppliers show compliance with important parts of health and safety law (the core criteria described in the CDM regulations). On achieving compliance a supplier is approved to work for all of CHAS’ buyers. Inconsistencies are reduced where some suppliers may be judged compliant by one buyer but not another. CHAS gives guidance on any weaknesses in a supplier’s safety management, including how they can improve.


CQMS are a leading third party health and safety organisation who recognise high standards of health and safety among UK contractors.

CQMS are part of the Safety Schemes in Procurement Forum (SSIP), an umbrella organisation that facilitates mutual recognition between health and safety pre-qualification schemes wherever it is practical to do so.


The National Demolition Training Group (NDTG) was formed in 1978 with the sole objective of providing specific and relevant training opportunities to demolition workers. Almost 30 years later, that objective remains at the heart of the NDTG.


 Acclaim Accreditation supports the objectives of SSIP (Safety Schemes In Procurement) to improve health and safety standards across the UK and reduce duplication of paperwork in procurement.


CSCS is the leading skills certification scheme within the UK construction industry. CSCS cards provide proof that individuals working on construction sites have the required training and qualifications for the type of work they carry out.
