EPC C by property type

Getting a Modern flat (post-2000) to EPC C

Flats built since the early 2000s were constructed to tighter building regulations and frequently already meet EPC C.

Why this type behaves the way it does

  • Insulated walls and roofs to modern standards
  • Double glazing as standard
  • Often efficient gas or electric heating

Measures that typically reach C

Low-energy lighting

Low-energy lighting

Swapping any remaining halogen or incandescent bulbs for LEDs is the cheapest improvement of all, and it appears on a surprising number of EPCs. It won’t move a property a whole band on its own, but as part of a package it’s an easy, instant win with no installer required.

Heating controls

Heating controls

A programmer, a room thermostat and thermostatic radiator valves let the heating run only when and where it’s needed, rather than heating the whole home all the time. Adding the controls a system lacks is inexpensive, improves the EPC, and is one of the simplest ways to trim a tenant’s energy bills.
