Are you renting? Probably a silly question given what you mentioned doing, but I'm being vague :)
Pyramid Power did our solar panels, and I was really happy with the service. They were good, their contractors were good, and while there were a couple of minor errors, they were very quick and professional when it came to fixing issues.
Upgrading old insulation is a good starting point. If I had the money, I'd be looking at double glazing. It's getting cheaper and is the norm in many other countries.
Because I'm home during the day, I keep half an eye on the outside/inside temperatures and humidity. So in the mornings I leave everything open until temp is close to even, in the afternoon/evening I keep the windows closed, and curtains drawn until the difference is 2-4 degrees, then open everything up.
