This site prints "not established" in six places. You are how that changes.
The kit, and separately the electrician if there was one. Those two numbers together are what nobody currently publishes.
This is the only way this site gets real UK numbers. We will publish ranges once we have enough of them to be worth publishing, with the date they were collected, and we will say how many they are based on. Nobody's details are published and no seller sees your message.
