You haven't heard the hype? £450 a year savings on a £500 heating bill.

Bring back the sarcastic smiley.

My heating is still on.

I assume you don't live in Scotland? 12 deg C at the beginning of the week.

I think there are a lot of silly estimates out there regarding energy savings due to cavity wall insulation.
It's reckoned that up to 35% of your heat loss is via the walls so inserting insulation should give you savings of between 10-20% (there will always still be some heat loss so you'll never save it all)
You should hope to get a reduction in your heating bills of around 10-20% depending on how bad the walls were before, how good your controls are and whether you've done a bit of draught proofing etc. So even assuming that you pay about £1000 a year just for heating (excluding hot water, cooking etc) the best you'd save is about £100-£200 a year, a long way short of the £400-500 being quoted, even by the Energy Savings Trust.
Obviously if you don't pay that much then you'll save even less.

However I do think it make's the place a bit more comfortable, it can reduce condensation and will help retain heat that's been generated by having people in the house and other stuff like the telly, lights and cooking
