In reality a CCGT and a CH condensing boiler are both about 65%
(thermal) efficiency : the kicker is that heat pump is, in terms of heat
out to electricity in, at least 200%, and up to 400% 'efficient'.

That means that overall CCGT plus heat pump is a less energy intensive
heating solution than a gas boiler.

How does that compare to a gas powered domestic heat pump? Presumably that
would out-perform CCGT + electric heat pump?
