We install MVHR systems all over England and Wales. We offer a full MVHR installation service, employing our own in-house team of engineers. Many of our competitors use sub-contracted labour or don’t offer installation at all, so it is important to check the small print when comparing MVHR quotes. We can guarantee continuity and quality as our in-house engineers are trained by us and are required to meet an extremely high standard of work to be employed by us.

At Earthwise, our dedicated in-house MVHR Design team is committed to guiding you through every step of your MVHR journey, ensuring a smooth and efficient experience.

At Earthwise, for your peace of mind, we provide a full turnkey MVHR service—from design to supply, installation, commissioning, and ongoing servicing. This ensures a hassle-free experience and optimal system performance. Find out more about this process, timings and how it works in our MVHR brochure.

What happens in an MVHR install?

Typically we would break the installation down into two stages, as follows:

1st fix MVHR install

What stage of the build is the 1st fix MVHR install?

  • We will need to install ductwork before any of your 1st fix plumbing and electrics takes place. This is because our ductwork is usually the largest, most immovable, service to be installed. If your plumber or electrician has already put their pipes/wires in, this can prevent MVHR ducting from fitting where it needs to go. This can obviously be very costly to sort out, so to avoid any issues the MVHR ductwork should always be fitted first.

How long does it take?

  • Materials are sent to the site a week before our 1st fix visit.
  • It usually takes one week (or longer for larger systems).

What happens?

  • All ducting is installed back to the position of where the MVHR unit will be. Air vent locations are set and intake and exhaust ducts (that go to the outside of the house) are usually installed.
  • Intake and exhaust ducts are fitted through the wall or roof.

2nd fix MVHR install

What stage of the build is 2nd fix install?

  • The 2nd fix MVHR install usually happens after your plastering has taken place, and at the same time that 2nd fix electrics and 2nd fix plumbing take place. If the MVHR unit is going in a place where it will be left on show, then you’ll need to have completed all the finishing works, such as painting. This is because once the MVHR unit has been installed it could be very difficult to get access to the areas around it to finish them.

How long does it take?

  • Usually 1-2 days (or longer for larger systems)

What happens?

  • The MVHR unit, control panel and air vents are sent to site before we arrive, or sometimes we bring them with us.
  • The MVHR unit/s is installed and any outstanding works to do with the installation are completed.

Can I install the MVHR system myself?

If you’d prefer to install the system yourself, we can offer a Supply only service. We would not recommend this with a steel ducted branch system due to the complexity and amount of parts required and the fact the design needs to be strictly followed. However, a semi-rigid (radial) system has far fewer parts and can be installed in an easier way. Please contact us about your exact requirements and we can work with you to find a solution that works for your project.
