BOPAS provides assurance to the lending community that innovatively constructed properties against which they may be lending, will deliver a consistent performance over a determined durability of 60 years.

The Technologies

The technologies involved in offsite manufactured systems and innovative construction techniques will change the construction landscape and BOPAS will ensure that they meet stringent quality criteria

Accredited Organisations

The designers, manufacturers, and constructors involved in offsite manufactured systems are rigorously audited and approved to maintain the highest levels of quality assurance throughout the process and ensure their construction systems are approved for integrity, durability and performance.

Lloyd Register

Buildoffsite Property Assurance Scheme (BOPAS)BOPAS exists to provide assurance to the lending community that innovatively constructed properties will be sufficiently durable as to be readily saleable for a minimum of 60 years. The scheme serves as the vehicle for the standardisation of best practice across the offsite construction industry.
With Building LifePlans Ltd (BLP), we accredit designers, manufacturers, and constructors involved in offsite manufactured systems, through an audit process designed to provide lenders with the highest level of quality assurance.

The scheme has been developed by Buildoffsite, The Royal Institution of Chartered Surveyors (RICS), Lloyd’s Register and BLP, in consultation with the Council of Mortgage Lenders (CML) and the Building Societies Association (BSA).

The scheme focuses on ensuring that accredited organisations have robust systems and procedures underpinned by a risk based approach which enables them to competently, and safely, deliver products or services which meet the requirements of their clients.

Benefits of using a BOPAS accredited organisation

Provides an assurance that delivery is through defined processes which meet best practice

Gives assurance that the processes and work controls across the supply chain are synchronised with each member working together with common aims, methods and objectives

Provides an assurance that risks to the project are comprehensively evaluated and mitigated

Quality management

The ISO 9000 family addresses various aspects of quality management and contains some of ISO’s best known standards. The standards provide guidance and tools for companies and organizations who want to ensure that their products and services consistently meet customer’s requirements, and that quality is consistently improved.


The letters ‘CE’ appear on many products that are traded on the single market in the European Economic Area (EEA).

The CE marking is required for many products. It:

shows that the manufacturer has checked that these products meet EU safety, health or environmental requirements

is an indicator of a product’s compliance with EU legislation

allows the free movement of products within the European market

By placing the CE marking on a product a manufacturer is declaring, on his sole responsibility, conformity with all of the legal requirements to achieve CE marking. The manufacturer is thus ensuring validity for that product to be sold throughout the EEA. This also applies to products made in third countries which are sold in the EEA and Turkey.

Not all products must bear the CE marking. Only those product categories subject to specific directives that provide for the CE marking are required to be CE marked.

CE marking does not mean that a product was made in the EEA, but states that the product is assessed before being placed on the market. It means the product satisfies the legislative requirements to be sold there. It means that the manufacturer has checked that the product complies with all relevant essential requirements, for example health and safety requirements.

If you are a manufacturer it is your responsibility to:

  • carry out the conformity assessment
  • set up the technical file
  • issue the EC Declaration of Conformity (DoC)
  • place CE marking on a product
  • If you are a distributor you must check the presence of both the CE marking and the necessary supporting documentation.

If you are importing a product that is from a third country you have to check that the manufacturer outside the EU has undertaken the necessary steps. You must check that the documentation is available.
