How we approach MVHR in Sidcup
MVHR works best in a home that is reasonably airtight: a new build, a deep retrofit with insulation and new windows, or a renovation where ceilings are coming down anyway. 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.
Retrofit in an occupied home
Ducts routed through the loft and down through cupboards or boxed corners. Most semis are done in 3 to 5 days.
New build or full renovation
Ducts go in at first fix before plasterboard, which is the cheapest and neatest time to fit MVHR.

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 Sidcup
Do you cover Sidcup and nearby?
Yes. We cover Sidcup and nearby places including Chislehurst, Bexley, Welling and Eltham. Send your postcode and we will confirm.
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.
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.
