Wall Insulation

Hi there, I am looking to increase BER rating from its current level of D2 in a bungalow with cavity walls built in the 70's. I will insulate the attic with 100mm Rockwool so should make a difference. The windows were replaced about 8 years ago with double glazed PVC. Not the best but will do for now. I am just wondering…

Hi there,
I am looking to increase BER rating from its current level of D2 in a bungalow with cavity walls built in the 70's. I will insulate the attic with 100mm Rockwool so should make a difference. The windows were replaced about 8 years ago with double glazed PVC. Not the best but will do for now. I am just wondering what is the rough cost per metre to pump the walls with beads.
Also just wondering the average cost of upgrading the heating system which is an oil fired one to a zoned heating system and replacing the boiler with a modern efficient one.
Guidance appreciated
