For organizations that require ongoing access to multiple standards, subscription services like BSI Knowledge or IHS Markit Standards Store provide access to BS 8558 as part of a licensing model, eliminating the need for single document purchases.
If you have an old copy of BS 8558:2011 on your hard drive, you are working with a dangerous document. As detailed, the 2015 edition reinstated critical sizing data and aligned the document with the latest health and safety guidance. Relying on the withdrawn 2011 version could result in undersized pipework or inadequate Legionella controls, exposing building occupants to risk and leaving you legally exposed.
According to (and updated in 2015), all new or modified water services must be thoroughly flushed with wholesome water. This is critical to:

The standard promotes designing systems that minimize heat loss, which is essential for sustainability and lowering operating costs, while still maintaining high temperatures for hygiene. Commissioning and Maintenance (Flushing and Sampling)
While BS 8558 remains the current standard (published September 30, 2015), the world of building services is evolving quickly. Modern heating technologies, such as heat pumps, operate at much lower flow temperatures than traditional gas boilers.
: Hot water should be stored at at least 60°C to kill Legionella bacteria.
: Keep pipe runs as short as possible (ideally under 3 meters).
