Make a DIY blowerdoor fan yourself before Aerobarrier come. 

 

You will get 90% of the way there by yourself.

It doesn't have to be a door of course.  Depending on the diameter of your fan, it might be easier to fit one to an opened window light.

Yeah we did a sheet of OSB with a fan in a window. It sealed nicely against the gaskets. Dead easy, just measure the tilt and turn sash and cut the OSB the same. 

 

It stayed in there for weeks.

We did the same but I used a variable speed dust extraction unit and even on the slowest speed I had to restrict the hole so much to get it to hold the pressure.

Did you manage to get any useful readings from it?

Yes - were within 5% of the official test a few days later.

The MBC package is the most complete one I know of. It's really well though out. 

 

The only bits I'm a little iffy about is the sparse window and threshold details. 

 

 

I can't fault them, Scan House just gave me a quote of £106 K for a the frame only without insulation and couldn't be bothered to provide a detailed quote. MBC are 90 K including insulation - their support service has been A1 in my view.
