What the work involves

Inside the unit the two airflows pass each other across a heat exchanger without mixing, so the incoming fresh air picks up heat from the outgoing air. Filters on both sides keep pollen and dust out of the house and keep the exchanger clean.

Summer bypass and boost controls

Bypass lets cooler night air in without heat recovery; humidity or switch boost for showers and cooking.

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.

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 Lewes

What is the price of MVHR in Lewes?

Guide prices for Lewes use South East rates: whole-home MVHR retrofit, 1 to 2 bedroom flat is typically £4,900 to £7,650 inc VAT per home. We confirm a fixed price in writing before any work starts.

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.

Is the survey free in Lewes?

For new installations on the UK mainland, yes. The survey is free and the quote that follows is fixed and in writing. Servicing, testing and repair visits are charged, and we confirm the cost before booking.
