What would be the process of fitting a new consumer unit? Would there be an EICR first? If so I should probably trace the lighting circuit and its junction boxes and tighten the terminals, so I don’t have to pay for more of the electrician’s time.

Okay, fair enough. I haven't noticed anything wrong with the wiring, no rust or green stuff, it seems to be in good condition. There hasn't been any electrical issues in the last 30 years. I can see that some of the cable clips have broken and when using strippers on a lighting cable it was...

No RCD. It's the original 1970's wiring. The cables to the sockets and switches are all in conduit in the walls. The plan is for me to replace the cables and accessories section by section, apart from the final legs to the fuse board and then get an electrician to replace the fuse board with a...

1.5mm Lighting circuit 5A fuse, 2.5mm Socket ring 30A fuse and 6mm Cooker circuit 30A fuse. It's tricky interpreting those methods in relation to this application. My understanding is that the gap between the cable and the PIR is not relevant although it shouldn't touch, but the cables need to...

This is a photo of the ceiling-floor void that I will be plugging with PIR insulation. In some of these sections there are cables running down the joists. Some are 1.5mm for light fittings, some are 2.5mm for the ring and on one section there is 6mm for the cooker circuit. I will be cutting a...

Okay, thanks! (y)

I have a tub of 'Monument' brand Tallow that I bought from Toolstation. On the label it states, 'Used as a lubricant for threading, pulling electric cables through conduit etc.' However, Google says Tallow can react with and damage PVC sheathing on twin and earth cables, so I'm confused. Can I...

I am currently installing insulation in the pink and purple areas to the upstairs of my parent’s chalet bungalow. I’m doing this while avoiding any destruction that would result in re-decorating. The pink area is to plug the floor void at both ends for three reasons: 1. Stop drafts that...

Would it be okay if I drilled a hole in the 75mm PIR and just fed the cable through into the back of the back box?

As it's a chalet bungalow, there are storage areas on each side of the house accessible via a hatch in the wall, so I am behind the bedroom wall. It is unheated. The difference in temperature between this storage area and and bedroom is between 2 or 3 degrees throughout the year. I will be...

Hello, I am fitting 75mm PIR insulation behind a plasterboard wall in a bedroom in a chalet bungalow. There are a couple of sockets I need to work around and am unsure about how to route the cables so I can fit the insulation. I have a photo showing the current cable routing and proposed...

Hello, I am looking to better insulate my parent’s 1970’s chalet bungalow as the upstairs is noticeably warmer than the downstairs. The upstairs also gets very hot in summer and cold at night and the living room downstairs can be very cold in the winter. The living room has large windows and...

Excellent! Thanks for your help. (y)

I will have to use a short length of trunking. What size would be appropriate for 2x 2.5mm twin and earth that has to negotiate a corner?

Ok cool. Thanks for your help. (y)

Hello, I’m a DIYer planning to add some sockets and resolve some double spur issues I have found on my parent’s mains rings. There are two 30A rings, one serving the front of the house and the other, the rear. As there are crawl spaces on either side of the house, I have been able to trace the...
