Survey (Qualitative)

Data (Quantitative)

Average capital costs of retrofit technologies (E.G. top 5 boilers on which are priced between...)

Reasons to retrofit to lowest requirement

Average savings in operating cost from each technology

Requirements for each EPC rating

Typical technologies used to increase EPC rating

Calculate the cost of each rating increase

Reasons to retrofit to a higher requirement

Consider selling property instead of retrofitting?

Don't own/buy any poorly rated properties

Buying properties to retrofit anyway so poor EPC rating doesn't matter

Why they would retrofit

Risk of penalties

Can charge a higher rent

Have to comply with MEES

Cheaper bills

More attractive for tennants

Churn rate

Types of building - old/new

Possibly more cost effective to retrofit to a higher grade since spending money retrofitting anyway so might as well pay a bit more to get even better energy efficiency and higher savings

(EPC's last for 10 years)

In discussion, say how prices vary between type of installation esp for new boiler (existing location/new location, size of house etc) type of window & size of house
