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.
New build or full renovation
Ducts go in at first fix before plasterboard, which is the cheapest and neatest time to fit MVHR.
Radial semi-rigid ducting
One small duct per valve from a manifold. Quieter and easier to balance than branched rigid duct in most homes.

Rules that apply in England
In England, ventilation is covered by Part F of the Building Regulations and its guidance, Approved Document F (2021 edition). 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 Gravesend
What area around Gravesend do you work in?
All of Kent. Near Gravesend that includes Tilbury, Swanscombe, Grays and Longfield.
Is MVHR worth it in an older house?
It can be, but the payback is best in a home that is fairly airtight. In a draughty house MVHR still gives steady fresh air and condensation control, but a PIV unit or continuous extract fans may solve the same problem for far less. We will tell you which on survey.
How noisy is MVHR?
Correctly sized and balanced MVHR is very quiet on normal speed; most people stop noticing it within days. Noise problems usually come from undersized ducts or a unit running flat out, which is why we design the rates first.
