MVHR for Larne homes
A single unit, usually in the loft, a utility cupboard or a garage, runs all the time at a low, quiet speed. Insulated ducts carry extract air from the wet rooms and supply air to the habitable rooms.
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 from Larne
What is the price of MVHR in Larne?
Guide prices for Larne use Northern Ireland rates: whole-home MVHR retrofit, 1 to 2 bedroom flat is typically £4,100 to £6,400 inc VAT per home. We confirm a fixed price in writing before any work starts.
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.
Is the survey free in Larne?
Visits here are by arrangement. Because of the ferry or long travel involved, we quote travel separately and in writing before you commit, and we can often combine visits to keep the cost down.
