The Energy Recovery Linac Prototype (ERLP) is a new accelerator being built at Daresbury Laboratory in the UK. The project is a research facility to develop the technology required to build a 4th Generation Light Source (4GLS). The vacuum science group of ASTeC* is responsible for the design of the vacuum systems for the ERLP machine and their subsequent commissioning. The ERLP project is the first at Daresbury to require XHV and as such has presented a number of challenges to the design team. This paper will outline the requirements for XHV for the ERLP and detail some of the challenges that have been faced. Some details of bakeout, particle control, measurement limitations and leak detection will be presented. @FootnoteText@ *Accelerator Science and Technology Centre of CCLRC
