On my previous device, iPhone 6 plus I never really had this problem on the same commute, the transition from mast to mast was seamless which is the way it should be as the overlap of the masts work this way.
When at home should't the better speed mast (4G at Coolmine) be defaulting for me if I restart or turn on or off data?
The one on the Navan road is much further away than that one.
Also for testing the service I did move to different areas of the house and same thing, sitting room in the front and kitchen in the back and same service.
Will do some speedtests later this evening when home from work.

Oh I just had a look and I see you've had the same SIM since 2013, and as it used to work in your iPhone and the service has changed when you swapped the SIMs, I reckon it's just a new SIM card that you need.
I would recommend getting a new SIM whenever you change phones, or even once a year if at all possible to make sure you're getting the best possible service.
Changing SIMs is free, you just need to pop into a Three store to pick up a blank replacement SIM and activate it here - http://www.three.ie/activate-my-sim/
