- From £4,225 inc VAT per home
- Free survey
We survey South Glamorgan homes for MVHR before quoting, because the duct routes decide the price more than the unit does.
Our team is based in Great Barr, Birmingham, and we work throughout South Glamorgan, from Penarth, Llantwit Major, Whitchurch, Rhiwbina and Cardiff. We survey first, free of charge for new installations on the mainland, then send a fixed written quote.

How we do it
Insulated ducts carry extract air from the wet rooms and supply air to the habitable rooms. 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.
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.
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.

Questions about MVHR installation in South Glamorgan
Which rules apply to ventilation in South Glamorgan?
In Wales, the Welsh Government's own Approved Document F (2022 edition) applies to ventilation in homes, with a new edition taking effect on 4 March 2027. Rented homes must be fit for human habitation under the Renting Homes (Wales) Act 2016, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.
How much does MVHR cost to install?
A typical retrofit costs £6,450 to £9,450 including VAT for a three-bedroom house, and £4,950 to £7,950 when it goes in during a new build or full renovation. Flats start lower and large detached homes cost more because of the duct runs. We give a fixed price after the survey.
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.
