  A multi-pass re­cir­cu­lat­ing su­per­con­duct­ing CW linac of­fers a cost ef­fec­tive path to a multi-user fa­cil­ity with un­prece­dented sci­en­tific and in­dus­trial reach over a wide range of dis­ci­plines. We pro­pose such a fa­cil­ity to be con­structed in stages. The first stage con­sti­tutes an op­tion for a po­ten­tial UK-XFEL; the linac will si­mul­ta­ne­ously drive a suite of short wave­length Free Elec­tron Lasers (FELs) ca­pa­ble of pro­vid­ing high av­er­age power (MHz rep­e­ti­tion rate) at up to 10 keV pho­tons and high pulse en­ergy (3 mJ) 25 keV pho­tons. The sys­tem ar­chi­tec­ture is cho­sen to en­able ad­di­tional co­her­ent sources at longer wave­lengths, de­pend­ing on com­mu­nity need. In later stages the scope of the pro­ject ex­pands; we pro­pose beam trans­port mod­i­fi­ca­tions to en­able op­er­a­tion in En­ergy Re­cov­ery mode. This en­ables multi-MHz FEL sources, e.g. an X-ray FEL os­cil­la­tor. Com­bin­ing with lasers and / or self-in­ter­ac­tion will pro­vide ac­cess to MeV and GeV gamma-rays via in­verse Comp­ton scat­ter­ing at high av­er­age power. Op­por­tu­ni­ties are also cre­ated for in­ter­nal tar­get and fixed tar­get ex­per­i­ments. We ex­plore pos­si­ble sys­tem ar­chi­tec­tures and out­line a path to con­firm fea­si­bil­ity through ex­per­i­ments.
