Thanks for the reply, that makes sense.
Just to clarify, does the ridge board need to be independently supported if it’s separated from the chimney, or is it normally only located by the rafters?
Also, when you say the gap needs to be identified and closed off with flashing or similar, are...
Hi all, hoping for some advice on an ongoing chimney leak that’s proving hard to pin down.
Background
A couple of years ago I noticed water ingress around the face of our chimney stack. A roofer found the chimney pot and flaunching were cracked and replaced them. When that didn’t resolve the...

We have a pressurised system boiler with two zone valves, controlling the hot water and heating circuits. We noticed that the radiators are hot when only the hot water zone should be open. The room thermostat is fine and I've narrowed the issue down to a fault in the zone valve...
I used the extension and found no voltage on cable 3 when connected to the known good earth. I then went ahead and connected cable 1 & 2 which resulted in 240V on cable 3 that could be turned on/off via the light switch. At that point I was happy, installed all the lights and it has been working...
Thank you so much! Should have used a multimeter from the start.
* Line 1 had 240V live to neutral and live to earth
* Line 2 had 0V on all cores when either or both of the mcbs were off. When they were both on I could see between 0.2V and 0.8V whenever I tested the cores, in all cases this...
Hello,
We've had an extension built a few years ago and are finally getting round to install some outdoor lights. The electrician at the time left the cables in place for us to connect the lights when ready without giving any further instructions. The plan was always to install two outdoor...
