British Standards Institution (BSI) has revised its PAS 2030:2017 specification for the installation of energy efficiency measures in existing buildings.

The updated PAS specifies requirements for the installation of energy efficiency measures in an existing building, applicable whether the building is used for commercial or residential purposes.


In response to recommendations from existing users of PAS 2030, the specification has been expanded to include definitive requirements for design aspects to be validated by installers, as well as specific methods, processes and procedures to be employed in commissioning installation and handover of projects.


The development of this revised PAS was sponsored by BEIS Home Energy and supports the Energy Company Obligation, the government’s energy efficiency scheme to help reduce carbon emissions and tackle fuel poverty. The revisions in PAS 2030 were prompted by changes in UK legislation relating to energy efficiency and to meet the requirements of suppliers and users of energy efficiency measures.


PAS 2030 is also recognized in the recently published Each Home Counts Review, which includes a recommendation for development of a Quality Mark in the domestic retrofit sector.


The revised PAS includes requirements for installation processes, process management and service provision. It also includes criteria relating to installation methods, equipment, tools, product or system and material suitability. The commissioning of installed measures and the training, skills and competence of the people undertaking such installation, is also covered in PAS 2030.


Ant Burd, head of market development for the built environment at BSI, said: “Older buildings are typically much less energy efficient than newly constructed buildings, increasing costs for home occupiers and business alike. PAS 2030 provides a dedicated specification for anyone who wants to install energy efficiency measures into an existing building, whether that building is a Victorian warehouse or a two bedroom apartment built in the 1990s.”


As well as installers of energy efficient measures in existing buildings, PAS 2030 is particularly relevant to certification bodies. PAS 2030 – available online and in PDF format – was launched with a dedicated online resource, which includes expert commentary and regular industry updates to keep purchasers of PAS 2030 abreast with developments in their sector.


The revised PAS does not include requirements relating to the certification of PAS 2030 compliance by independent third parties, which is covered by PAS 2031. PAS 2031 was developed in conjunction with PAS 2030, and is scheduled to launch in March 2017.
