    Ducting question

    Hi, I'm planning to bury some 50mm ducting under my drive to carry SWA (two circuits) and x3 external CAT6 cables. The run is only about 6 meters under a gravel driveway. Each end will terminate at a brick wall (my garage and garden wall). While unlikely I'll need to use it again, I'll include...

    Cosmetic or Structural Cracking? Expertise please

    Hi, We're about to embark on a significant renovation project on a 1970s detached house we recently bought.

    Hi, Daft question I'm sure, but I'm laying SWA (about 40m of 10mm2) to a new workshop building which will have its own CU, circuit and ground spike. I want to do the donkey work and laying the cable before calling a pro to terminate etc. I was surprised by the difference in price between the 2...

    Metal Clad Sockets: Advice installing

    Hi, I'm planning to install some basic Screwfix metal clad sockets into an outdoor workshop that has chipboard interior walls. I'm conscious these sockets are typically installed as part of a grid system with conduit. In this case, however, the 2.5mm cable runs behind the chipboard walls. It...

    Size of cable to shed?

    Hi, I’d appreciate any insight on the following matter. I’m having 5 dual gang sockets installed in a relatively large tool shed. I’m not planning on any large loads, namely a some battery chargers, LED lighting and a powered table saw. I would estimate the maximum load to never exceed 20A. The...

    Rewiring Fun. Estimating the Age of Electrics

    Hi, I'm about to take leap of faith buying a property which I've not been able to see properly. It has a been extended a couple of times since it was built in 1970 and the current owner has no idea about the history of electrics, no certificates of any kind and doesn't want any visiting...

    Flat Roof: Converting Cold Deck to Warm Deck

    Hi, Would really appreciate any experienced view on an approximate price range to convert a 9m2 ‘cold deck’ flat room to an EPDM 'warm deck’. The roof is in good structural condition but I’ve been informed by a surveyor that this should be upgraded to a warm deck standard. I'm working on the...
