It’s been brought to our attention that our back door is not legally wide enough. We’ve been in our new build for 8 years (it was new when we bought it). I’ve always thought our back door was a squeeze. It’s a sliding patio door. We had a carpenter in to give us a quote on some new fencing and he commented that he didn’t think it was legal. It slides open 19 inches.
Does anyone know how I can go about checking this? I’ve had a look online but I’d like to get my facts straight before I write to the builders. Many thanks.
