Yorkshire conservatories in Barnsley did our new composite doors recently. Reasonable price and did a very good job. You can design your door and get a price from: https://compositedoorworld.co.uk/
The new composite ones are better than wood. Available in many colours, don’t rot, strong and safe, multi point locking, etc...
Nothing’s better than wood for appearance imo. I can see the ‘plastics’ are improving in appearance but they’re not for me. Just read back the whole of this thread. What has life become!!
