UK has the resources
UK has several options, not necessarily satellite based only. For instance eLoran has been discussed and can in many ways be far more resilient than satnav where all systems (GPS, Glonass, Galileo, Beidou, QZSS etc.) all use the same bands while eLoran is on a very different band.
Also a UK only system can be based on 3 x 3 satellites in Molnya orbits, reusing Japanese QZSS tech. Reusing tried technologies with few satellites would be a lot cheaper than Galileo will be.
