Nationwide Scheme
Reduced energy consumption isn’t the only advantage to switching to a central heating system.
A central heating system makes it much easier to maintain a consistent temperature throughout your home when compared to electric heaters.
A modern central heating system can improve the value of your home, as well as making it easier to sell.
Most central heating systems are compatible with smart thermostats, which makes it easy to control the temperature of your home when you’re away.
EPC RATINGS
Majority of properties in the UK have an EPC ( Energy Performance Certificate), if a property does not have one or it has expired, customers will get one on survey.
You can use this service to find an existing:
Energy performance certificate (EPC)
Display energy certificate (DEC) for a public building
Air conditioning inspection certificate and report
The EPC will tell indicate what rating a property is. 7 bands in total, A, B, C, D, E, F, G All properties that currently qualify are D, E, F G rated properties.
This website will give us indication on property type and sq meters along with the current band rating.
The EPC register will also advise the type of heating source currently in the property.
If a band can be improved by 2 SAP ratings, ie from an E to a D then it would qualify. In order to do this you will need to conduct the insulation measures first followed by the heating controls.
It will then advise what measures can be installed along with the typical annual savings for the customer.
