Passive house experienced contractors in south east London

[WisteriaMews]

Does anyone have any recommendations for passive house experienced builders that operate in south east London?

 

We are hoping to issue our tender soon for the house we're aiming to build to a certified passive house standard. We'd ideally like a contractor experienced in the passive house approach so they are across all of the necessary airtightness and thermal bridging requirements etc....

 

I've looked on the Passive House trust and AECB websites, but south east London seems to be a bit of a desert for registered contractors!

 

We have spoken to one contractor who has sent someone on the PH contractors training course, but they have never done a passive house project.

MBC is very well regarded in the timber frame space and they are national.

We have a timber frame company hopefully lined up (MBC weren't interested due to our foundation design). We're searching for a follow on contractor that will know how to install windows to a passive standard, wont puncture lots of holes in the air tightness layer and just generally buy into the concept of what we're doing.
