What the work involves
In a draughty older house it still ventilates well, but less of the heat-recovery benefit is felt because warm air escapes through gaps instead of the unit. We check this on survey and tell you plainly if a simpler system would do the job for less.
Radial semi-rigid ducting
One small duct per valve from a manifold. Quieter and easier to balance than branched rigid duct in most homes.
Summer bypass and boost controls
Bypass lets cooler night air in without heat recovery; humidity or switch boost for showers and cooking.

Rules that apply in England
English building work follows Approved Document F (2021 edition) for ventilation rates, installation and commissioning. For homes, it sets minimum extract rates such as 15 litres a second for a bathroom and 30 or 60 for a kitchen, and expects mechanical systems to be airflow-tested.
Questions from Blackheath
Do you cover Blackheath and nearby?
Yes. We cover Blackheath and nearby places including Lee, Kidbrooke, Greenwich and Ladywell. Send your postcode and we will confirm.
Do I keep my trickle vents with MVHR?
No. Under Approved Document F, background ventilators should not be installed with a whole-home MVHR system, so we advise closing or removing them once the system is commissioned.
How often does MVHR need servicing?
Filters usually need changing every 6 to 12 months, and a full service with a clean and airflow check once a year keeps the system efficient. Clogged filters are the most common reason MVHR stops working properly.
