@fitheach I am surprised that metric only tapes aren't widely sold - irrespective of Brexit, building materials have been sold in metric for the bulk of my lifetime and every modern building plan and DIY guides I have seen use metric...
@fitheach Yeah, painful: mine was about £14/metre for the first batch earlier last year and £21/m for the most recent lot (0.7 mm plastic coated).
Paul Camilli on Raasay seems to be pleased with the prices he got from Planwell in Buckie: https://lifeattheendoftheroad.wordpress.com/2021/11/25/going-for-a-new-roof/ but they only do trapezoidal AFAIK and I specifically wanted sinusoidal to be able to match up to windows less badly.
