MVHR installation in Mid Glamorgan

We survey Mid Glamorgan homes for MVHR before quoting, because the duct routes decide the price more than the unit does.

Mid Glamorgan has every kind of building, from old terraces to new estates and business parks, and every job is designed around the building in front of us, not a standard kit.

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.

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.

Radial semi-rigid ducting

One small duct per valve from a manifold. Quieter and easier to balance than branched rigid duct in most homes.

Questions about MVHR installation in Mid Glamorgan

Are prices different in Mid Glamorgan?

Our guide prices are adjusted by region. In Mid Glamorgan we use Wales rates, so whole-home MVHR retrofit, 1 to 2 bedroom flat is typically £4,225 to £6,600 inc VAT per home.

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.

Is the survey free in Mid Glamorgan?

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.

Which rules apply to ventilation in Mid 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.

Every MVHR job in Mid Glamorgan finishes with a measured commissioning sheet, so you know the system does what it should.
