David, as the GPS I use sits directly over the Pi I’ve just started a cron job to collect the CPU temperature every 10 minutes, which I’ll run for 24 hours or so, but was wondering if you (or anyone) could offer suggestions with regards to keeping temperature constant in a normal home environment (room heated but only as needed and not overnight, computer and GPS placed near a window through necessity (GPS antenna is placed on the window sill)). Any advice much appreciated.

Quick and cheap test to see if you get the results you need. Put the combination in a closed cardboard box to protect it from air currents and if you can find something suitable, surround the r-pi and receiver in the box with some thermal mass, or even foam to lessen temperature gradients. You may have to poke a few holes in the top if the cpu temp gets too high.  If you find you need better, prettier, you can use the pi itself to control a fan to regulate box temp. Plenty of sources on the web.  I myself am just using an insulated cardboard box without fan for one. It is fine for NTP.
