CIBSE CP1 (2020) goes free to all!

Monday 13th May 2024
CP1 (2020), the recognised Code of Practice for heat networks in the UK, is now freely available following an agreement between the Chartered Institution of Building Services Engineers (CIBSE) and the Department for Energy Security and Net Zero (DESNZ).

CP1 contains technical guidance and sets out voluntary minimum standards for UK heat networks. Having most recently been updated in 2020, CP1 will be the basis for the minimum regulatory standards used within the Heat Network Technical Assurance Scheme (HNTAS).  

Since it was published, CP1 has gained widespread acceptance and support across the sector. It has been used as the go-to technical publication and is also used by developers to specify technical standards they require for their new heat networks. However, until now it’s only been free to CIBSE members. A partnership between CIBSE and DESNZ has now removed the paywall to make CP1 (2020) free-to-all.  

To download a free copy of CP1 (2020), simply register at the CIBSE website and use the voucher code FREE.

DESNZ is also working with CIBSE to update the voluntary Code of Practice throughout 2024, to ensure continuing alignment with the HNTAS regulatory technical requirements that are also in development. The aim is to publish the next version of CP1 as a download that is freely accessible to all in 2025.  

CP1 (2020) is therefore not an exact representation of the standards which heat networks will be required to follow within regulation. However, it does give a very good starting point in that CP1 (2020) compliant networks will be very well prepared for forthcoming regulatory technical standards.
