Try uk.d-i-y.
But - the important thing is insulation. More of it than you think. Don't just go with what the building regs require, put _lots_. Double glaze it - then add secondary glazing too. put a foot in the roof. Fill the walls with insulation.
The most economic solution will be a heat pump - but whether the cost will be paid back in the lifetime of the building is another matter.
And I do hope you _do_ have planning permission? And Building Regs? If you don't they could force you to demolish it!
