Temp gauge low and heater not very warm

Hi. I have UK market 2000 model year 3.2 XJ8.
When running (especially in cool evening temps here in the UK) the temp gauge doesn't get much beyond 25% from cold. It will get up to 50% if it left to sit and idle. Additionally the heater at full heat doesn't feel as hot as I think it should be. Could this be a faulty thermostat? I'm aware the temp gauge is software driven so may not be a true reflection of engine temp.
Any clues where to start diagnosing?
