r896neo Thanks for that, that makes perfect sense, Ipresume i'm going to need welly's?

I'm converting my garage into a habitable space and have excavated the base and in-filled with MOT, sand blinding layer, DPM and 100mm insulation boards with 25mm upstand. I'm now ready to lay the concrete, any ideas on the best method? The upstands are level with the DPC but I want the...

I have excavated the old garage floor as the area is going to become a habitable space and I have some queries. I have layed some type1 mot (100mm) and compacted with a wacker, on top of this I am about to lay a thin layer of building sand (10mm). I have 100mm insulation boards to go in...

ban all sheds Thanks, it's ok to use 20amp then, and 5amp for the lighting radial? if that's safe i'd prefer that as 30's are a bit bulky for the space. thanks again

Thanks for the replies. The JB's are a temporary measure until I get the time to extend the rings correctly. 30 amp JB's for power and 5amp for lighting it is then.

In response to my first post all is now well! I have used two seperate JB's, one for out going and one for the return. The power circuits are on B32's can I use 20amp JB's and 5amp JB's for the lighting radials?

ban all sheds I am trying to do as much of the donkey work as possible, the electrician will be doing the kitchen wiring, I am just creating a bank of JB's for the electrician to connect to for the rest of the house.

I need to move my consumer unit to an opposite wall as the wall it's on is going to be demolished and therefore I need to extend all the rings and radials. An electrician said the best thing to do would be to put a bank of junction boxes within the ceiling void with a trap door. Here's the...

Thanks for all the advice and guidence, I shall now contact an electrician and ask him to prepare a design with agreed intervals of inspection before finally signing off. Thanks again.

Yes I know it's notifiable and they have been notified. I want to do the donkey work and get an electrician to then check it and sign it off. Would just like some pointers on the correct method.

Can anyone advise if this will meet building regs? Create a ring main with 2.5mm cable to supply five double power points above the worktop and spur off to dp power points below the worktop for a dishwasher washing machine and tumble dryer to plug in? Will also run a length of 6mm for the...

Taylor Yes I've notified BC as it's part of a garage conversion. My understanding is that I can do the wirin myself and then pay the extra bdg notice fee to have it signed off? Here is the scheme.... My consumer unit is in the garage which will become the new kitchen. I was...

Thanks for the quick reply. Rewiring a kitchen, was going to go for a simple ring main with fused spurs for the appliances or is that not necassary i.e. just spur off with power points? and a 6mm supply for the built-in cooker. Plus extend the groundfloor lighting radial to add some sunken...

Am I right in thinking that 2.5mm is still the required size for power and 1mm for lighting?

Which Celotex should I use for under floor, BC want 90-100mm depth. I see there's different types! Many thanks

Sorry, one more thing, what is a 25mm perimeter?

One more thing, well two actually! Will need to run a gas supply under the floor for a hob in a central island and also power for said hob and a couple of other appliances (fridge & freezer). Should I just run a length of copper say 15mm for the gas supply within the floor once I get to...

Just been reading up on excavating as will be doing my own floor preparations for garage conversion. Does this sound ok or is there a better way? Excavate and lay and compact 100mm of MOT then 5mm sand then 90mm celotex/kingspan? then dpm then concrete depth?? then screed 75mm. Any...

One more thing. I've been told the old garage floor slab will need to come up, any ideas on depth that will need to be excavated below finished floor level and what it consists of i.e. so many mm of mot/sand insulation/concrete and top screed dpm what order etc?

I have started excavating my footings where my garage door is (window and 15 courses of bricks replacing door) in readiness for the building inspector. I have found out that the house sits on 8" footings, however a couple of people have told me the BI will want a1M footing for the infill. I have...
