A drier, healthier home; without opening a single window.
Modern British homes are airtight by design, and condensation, mould and stuffiness are the side effects. Mechanical ventilation quietly replaces stale air with filtered fresh air, recovering up to 90% of the heat on the way out.
MVHR is the gold standard for new builds and deep retrofits. PIV is the cheap, fast fix for older homes with damp problems. Neither is hard; both are routinely badly specified by installers who don't measure. Get the design right and you get a house that always feels fresh, without ever feeling cold.
