What to consider
Home energy explained
Using less energy
Review bills and meter readings, then identify heating, hot-water and appliance use before choosing improvements.
Heating and insulation
Compare the building fabric and heating system together. A suitable sequence depends on the property and its occupants.
Generating and storing electricity
Solar panels and batteries can change when a home buys electricity, but results depend on the roof, usage and tariff.
Smart controls and grants
Controls may improve how energy is used. Eligibility and grant terms must be checked against the current official scheme.
