One of the primary reasons buyers choose new builds over older properties is energy efficiency. With rising energy costs, a high EPC rating is a major selling point.
However, if the construction quality is poor, your “A-rated” home might be performing like a “C-rated” one.
Thermal Bridging and Insulation Gaps
The most common issue we find in new builds is incorrectly installed insulation. If there are gaps in the cavity wall insulation or the loft rolls aren’t tucked into the eaves correctly, “cold spots” occur.
This leads to heat loss and, eventually, localised damp and mould.
The Role of Air Leakage
New homes must meet strict air permeability targets. During our detailed snagging reports, we often find missing sealant around window frames, pipework, and skirting boards.
These small gaps allow warm air to escape, forcing your heating system to work harder.
Smart Homes and Renewables
Many new developments in Devon and Cornwall now include solar panels or air-source heat pumps. These systems are complex and often poorly commissioned by subcontractors.
Part of a thorough inspection involves checking that these systems are installed to the manufacturer’s standards.
How Snagging Saves You Money
By identifying these “invisible” defects early, you can hold the developer to account. Fixing insulation or sealing draughts ensures your home is as cheap to run as the brochure promised.
Don’t take your energy rating at face value. Ensure your home is as green as it’s supposed to be with a professional inspection from Snagmaster SW.
