Certain things do seem to be early here, though not specially so. If naturescalendar statistics are anything to go by – many things (most) are later than what happens further south. Autumn comes early too or, to put it another way, summer is much shorter here than in many parts further south. I actually got The Woodland Trust naturescalendar survey to change something because they kept asking if I was sure I was seeing what I was reporting (early yellowing of silver birch leaves, for instance; I was sure and I sent photos). I argued that they had a preconceived idea of when natural things "should" happen and so they had set time limits in the survey. They've removed those limits now as they agreed that a scientific survey such as they are doing is about observing and noting what actually happens without particular expectations.
Another interesting thing we've found here is that even 30 metres altitude above sea level can make as much as two weeks' difference to when certain species flower.
You may find spring is earlier where you are now, jess, than it was when you were in MK. We found nights in Oxfordshire could be as cold as in Edinburgh and spring frosts as late. The west of Britain is generally milder than the east because of the greater influence of the Atlantic currents. You might find it breezier too. I missed fresh wind when I lived in the Oxon bit of the Thames and Cherwell valleys.
