But what is an EPC? How is it calculated? What does it tell you? What is an EPC classification? Get your EPC Certificate in London.

What is an EPC?

In short, an Energy Performance Certificate shows how efficient the energy of a building is, how efficient it could be and how to get from one to the other.

How is an EPC calculated?

A London Property Inspections consultant, the person qualified to produce an EPC for your property, considers three important things:

The size of your property. The first thing a consultant will do is measure the volume of your property. This shows them the exact amount of space that needs to be heated.
How to heat your property. Do you have a gas boiler? If so, how efficient is it? If not, what energy source do you use to heat your home? What does heat radiate? (floor heating, radiators) How do you regulate this heat? (a timer, TRV, room thermostat)
How do you keep that heat and energy in your property? In other words, how easy is it for heat to escape when you heat your home? Do you have a decent loft, wall insulation?

What does it tell you?

Your EPC will tell you how efficient your property is and how efficient it could be. You also get a list of measures that would improve the energy efficiency of the property. For example, if the building has walls with non-insulated cavities, it will show how much more efficient the insulation would be.

What is an EPC classification?

The EPC gives you two scores of 100 for your property. These scores correspond to an A-G letter rating system (A is the most energy efficient). The first score shows the current EPC classification of the house, the second score shows the EPC classification in case all energy efficiency measures are installed.
