Local EPCs for Caerphilly properties
Caerphilly has a clearly defined housing mix, shaped by the town’s growth around Caerphilly Castle and its development as a commuter town for Cardiff.
EPCs are commonly required for properties in areas such as:
Lansbury Park – predominantly post-war housing, where insulation levels and heating systems can vary significantly
Mornington Meadows – newer residential development, often achieving stronger EPC ratings than older stock
Central Caerphilly – traditional terraced housing close to the town centre and castle, sometimes with solid walls and older construction methods
Because EPC ratings are influenced by construction age, insulation, and heating systems, properties across Caerphilly can produce very different results even within short distances of each other.
What happens during an EPC assessment?
During an EPC assessment in Caerphilly, the assessor will typically review:
Property size, layout, and age
Wall construction and insulation (where visible)
Loft or roof insulation (if accessible)
Heating system, controls, and hot water provision
Windows, glazing, and fixed lighting
The assessment is non-invasive and usually takes 30–60 minutes, depending on the size and type of property.

In most cases:
Appointments are available within a few days
