	In this paper we present an overview of current and proposed FEL developments at STFC Daresbury Laboratory in the UK. We discuss progress on the ALICE IR-FEL since first lasing in October 2010, covering the optimisation of the FEL performance, progress on the demonstration of a single shot cross correlation experiment and the results obtained so far with a Scanning Near-Field Optical Microscopy beamline. We discuss a proposal for a 250 MeV single pass FEL test facility named CLARA to be built at Daresbury and dedicated to research for future light source applications. Finally we present a brief overview of other recent research highlights.

	The ALICE facility at Daresbury Laboratory is an energy recovery test accelerator which includes an infra-red oscillator-type free electron laser (IR-FEL). The longitudinal phase space of the electron bunches and the longitudinal transport functions in the ALICE accelerator are studied in this paper.

	Ultrafast lasers are able to generate THz pulses with >1MV/m field strengths, and with controllable electric field temporal profiles. We report on an experiment to demonstrate the use of laser generated THz pulses to manipulate the γ-z correlation of a ∼ 20MeV electron bunch on a sub picosecond time scale. The manipulation is achieved in free space, without external magnetic fields or undulators, by the interaction of the bunch with the longitudinal electric field of a co-propagating THz pulse in a TEM10*-like mode. We discuss the potential for arbitrary phase space control, including the possibility of correcting temporal jitter and driving electron beams into synchronisation with the laser.
