MVHR Retrofit Building Regulations

[arbennett]

Hello,

 

I'm a long time lurker, but first time poster. 

 

We're planning installing an MVHR in our bungalow which we have been working to retrofit airtightness as much as possible. When retrofitting an MVHR is it notifiable under building regulations? I plan to self install, with my electrician doing the electrical connection during our rewire. We're not undertaking any other 'building work', but do plan to replace a few doors and windows which will require a visit from the BCO as a non-fensa registered builder relative will be installing them for us. We don't intent to have trickle vents in the new windows so don't want to get caught up after install during the BCO visit for the windows.

 

I'll be giving them a call over the coming week but figured someone may have similar experiences. 

 

If it is notifiable work, am I right in that they will just require a commissioning report which I can complete myself?

 

Thank you!

AFAIK, only notifiable as part of a wider ventilation change, I.e. if you're changing windows now you have to ensure you allowing sufficient air changes per room, and need to show how the MVHR unit allows for that.
