What does the panel think?

I doubt if you would find one more than approx 3m to 4m. The weight and
base width rise quite a bit in a non-linear way the longer the
telescopic ladder.

Your gutter is probably more like 6m from the ground and for a ladder to
reach with the required lean you probably want more like 8 to 10m.
Ideally you want a ladder that reaches beyond the gutter. Working on the
inside of a gutter from a ladder that only reaches to below the gutter
is a PITA and possibly considered dangerous.

Screwfix do one at 4.4m.

I saw this one on Amazon:

but I wouldn't feel very confident with it's strength.

A 2 story Victorian house typically has higher than average ceilings too.
