Hello, new to the forum and still finding my way around so apologies if this has been covered before.
We are starting to renovate a house built in around 1800, which is not listed or in a conservation area. The exterior brickwork is crumbling badly all over on one side (possibly not assisted by application of regular masonry paint in previous years). We thought of repointing with lime mortar and then rendering the whole house with a lime based render, but then I looked at Part L1B - insulating render is out of budget, insulating internally not practical.
Part L1B effectively has an exemption if the cost of the work wouldn't pay for itself in reduced heating bills over the following 15 years. My query is how would the heating costs be calculated - the only heat source in the house is a wood burning stove fuelled by wood cut from the fairly sizeable garden, so effectively, the heating cost is zero! There is one gas fire in the kitchen, which along with the cooker, runs off LPG, but it is never used.
Many thanks.
