Do you really need 32mm the whole way into the house? We've a ridiculous length of 32mm from the road tapping down to the site, but I added another toby at the side of the house (so no need to drive up the lane) and came out of it at 25mm for the short run into the utility.
Our installer works with Spectus

and was happy to produce oversized openers just by adding a rider to the warranty.
the internal bore of the flexy is much less tho, and some are better than others. Those looks like JG ones, so the hose is only 13mm inside.
Whilst eg BES item 13753 is compression, it's also 19mm bore, much better flow
