Hi, Just looking to get some advice on improving the BER in the house. Have been getting a few quotes for different things but want to know what are the best investments and will make the biggest difference.
House is 19 years old, 4 bed semi, BER from 4 years ago was C2 and all we have done so far is switch lightbulbs to LED. Our bills aren't terrible at all but we would like the house to be more comfortable.
Construction of house means external insulation is the only option for the walls which is the only thing we aren't really considering because of the price (15-20k+ incl grant). What we are considering is;
*Attic insulation (seems like the main no brainer)
*Replacing front and back door with composite and triple glazed glass (Quote 3600)
*Replacing open fire with a stove (probably wood burner)
*Replacing all window glass to lowEplus glass (Quote 3700)
*Replacing original gas boiler to energy efficient one with heat controls (Quote 1800 incl grant)
*8 solar panels with battery(Quote 8600 incl grant)
So lots of options but just want advice on picking the best ones. Ideally we would also like to be able to achieve a B3 energy rating as we could then get a cheaper rate on our mortgage. Not sure what ones improve the BER most.
Any advice greatly appreciated, TIA!!
