In direct heating terms, probably not - as a large proportion of our
electricity will continue to be generated from fossil fuels, even when
more nuclear power stations come on stream (plus the costs of cleaning
up emissions from both existing and new fossil fuel power stations).

However, electrically powered ground/air source heat pumps might
become much more attractive, as they already have a considerable
efficiency advantage over direct heating.

The initial costs are considerable though, and your site must be
suitable.
