Aluminium laser cutting in the UK

I am looking for a recommendation of someone in the UK who could do some decent quality laser cut parts in 4 and 3 mm thick aluminium for a reasonable price. Not a huge job few brackets and parts of XY of a corexy printer.

I think laser cutting is the best option. Can you point me in the direction of someone that could help?

Laser cutting ally accurately takes an oxygen free atmosphere. Which isn't as cheap as water cutting.
