Gas will be around for some time yet. When I started 35 years ago it was due to run out in 2012 but here we are with new discoveries all the time, got to get through the gas to get to the new oil fields found so will certainly be ok for a few decades yet.
Renewables will come in slowly, I say slowly as the government keep coming up with new hair brained ways to mess up introduction of new technology e.g. the green deal, cert, eco, loose Kyoto targets and god knows what new ones.
As for technology and focus. As the boilers get better, breakdown rates lower hence longer guarantees, I think we will see the recognised split between a non specialised service only engineer and a more specialised repair engineer with greater skills around fault finding and electrical knowledge.
