EPC (Energy Performance Certificate) · Morlaix

The EPC and Morlaix’s older stone housing

In Morlaix, much of the housing stock is made of stone houses, longères and historic town-centre homes with thick, often poorly insulated walls. These features weigh directly on the energy rating: many older properties land in E, F or G, with a genuine « thermal sieve » concern when selling or letting.

Our local reading of the EPC factors in the mild but damp and windy Breton oceanic climate, which shapes heating needs. We separate what stems from insulation, heating type and ventilation, so the A–G result reflects how the home actually behaves in northern Finistère.

• Longères and thick-walled stone houses
• Historic, terraced town centre
• Newer homes in surrounding villages

How is a DPE carried out in Morlaix?

Faced with the longères and stone houses of northern Finistère, the assessor evaluates thick walls whose thermal mass and original insulation vary widely. They measure the surface, examine the heating - wood, electric or oil depending on the property - hot-water production and, above all, ventilation, decisive in a damp oceanic climate. These readings feed the 3CL method.

Our assessors travel to the most remote villages in the area. Arrange access to the loft and outbuildings, and gather your insulation records: on this older stock, they can markedly improve a starting rating that is often low.
