Did you pay by credit card ? If so start a claim back. The process starting will kick them into gear.

He is using independent ground workers, builder for the shell and individual trades for the interior. Sorry do not have further details, he told me the price was higher than anticipated and has abandoned the idea.

and look into the cost of a basement, my neighbor was quoted an additional 200k on his build for a basement in a 4 bedroom house.

What was the outcome of your DIY CEMP ? I have just had a requirement of an approved CEMP before work can start. Crazy for a diy self build. there are 6 individual plots all applied for planning permission within weeks of each other, two have the requirement for a CEMP, four do not.

You only have to comply at the time the house was built, you do not need to update the house to the current regs when you sell the house. not sure what additional value triple vs double would add to the value of the house, I would look at it has potentially saving x amount on heating costs, planning to live there Y years.

ahh ok, I was looking at the schneider range, I didn't realize the single phase MCB's/rcbo's would be interchangeable between easy 9 single phase CU and KQ 3 phase boards. Is it straight forward to assign what phase the each mcb/rcbo is connected to ?

Thanks for your feedback regarding the MHVR, I could put an extractor with ducting to the loft as I have a access run for the MHVR close by. Could use a temperature controller to switch the fan on/off as required.

Just realized I added that up wrong it is 82cm required for a pivot. I have a mid atlantic rack here that I did my network build on to have a play ready for the new house, on the basis I would be short on time with other stuff to play with IT gear. I have seen some pull out racks on rails that would work for your install. 12U Slide Out Open Frame Network/AV Rack - Server-Racks | United Kingdom (startech.com)

Just measured it, mine is the 17" not 22" depth. The wall plate to the pivot pin hole is 16cm The pivot pin in the rack is 66cm to the diagonal corner. 72cm+ minimum space required to full pivot.

Goya or Marranello

looks similar to some Nellissen Belgium bricks I have looked at.

Just seems somewhat overkill as I would need a large 3 phase distribution board and probably an extender, filled mostly with single phase MCBO's The single phase MCBO.s RCD's ect for 3P units are significantly more expensive than compared to their 1P brethren.

Accountant advice is to live in the house for 24 months from completion, moving on has to be for a valid reason e.g new job, move to different area, downsize ect. Multiple self builds in the same location will be treated as a developer not a self build.

I'm not an electrician, this is all based on what I have researched for my own install.

My understanding is the meter "tails" to the consumer can pass pretty much straight through a cavity wall to a consumer unit, they cannot be longer than 2M. and cannot run or change direction in a cavity. If they are longer than 2M an intermediary switch/isolator is required. If the meter tails need to be run to a consumer unit they need to be protected in metal trunking

Obviously this will be done by an electrician but would like to have a good idea on an approach so I do not get over engineered or over charged by Electricians doing the work. I have a bunch of questions. We hit a bit of a curve ball on the service plot we have bought with that the 125mm duct in the new road it seems doesnt exist as per the drawings.... looks like the new road is getting dug up. So assuming that gets sorted we will have a 3 Phase connection to a GRP meter cupboard at the edge of the plot. First is to sort out a temporary supply for the build. Assuming 3 phase supply and a 3 phase meter in the GRP kiosk. The build only needs a single phase. Can a single phase consumer unit be hooked up to a 3 phase meter, or do I need a small 3 phase distribution board right from the off ? the CU/DB will go into a surface mount meterbox on the side of the site office (Shed) along with a couple of double sockets. Once the build is finished a 3phase SWA cable will be used to connect the GRP kiosk to the dedicated plant room in the house, and we have the following needs(big power wise) 3P 16KW 3 Phase ASHP 3 Phase Car Charger. (Maybe two in the future) 10KW 3Phase Solar 1P 32A Hot Tub 3x 16A garden heaters Double Oven Steam Oven Plate Warmer 2 x Dishwashers 2 x MHVR units Tumble Dryer Washing Machine. Large electric fire in living room. My thinking is something like this. A medium size 3 phase distribution board, (12 way ?) for all the 3 phase MCB's 3 x single phase consumer units. and spread the load. unit 1, Washing Machine, 1 oven, 1 dishwasher and upstairs sockets and lights Unit 2, tumble dryer, 2nd oven, 2nd dishwasher and downstairs lights and sockets Unit 3, Hot Tub, Outdoor lights. garden heaters, indoor fire. The reason for doing this I can use 3 pre-populated schneider single phase consumer units, for a much lower cost than a large 3-phase distribution board with extension units considering the cost of the MCB/RCBO (1P or 3P) in the 3P distribution board. Space in the plant room isn't really an issue. am I missing something ? or making this way more complicated than it needs to be ?

My network/AV build is as follows. 2 x Middle Atlantic Wall pivot rack (16U) 1st rack Cisco 8 Port POE switch Cisco 48 Port Gigabit switch 2x2.5Gb Fibre trunks between switches. 48 port patch panel TP Link cloud controller. 6 x TP Link Access Points Sonicwall Firewall EMC NAS Bunch of smart home stuff. I should of got a bigger POE switch. I am on the limit of the poe output and have no further upgrade potential. The 48 port switch has 32 ports used, I have swapped the fans out for noctua's to reduce the obscene noise it produces. 2nd rack Pioneer AV Receiver (Living Room) Pioneer AV Receiver (Family room) Yamaha Network Amp (Garden) The house has a T-shape stairs, with two separate under stair cupboards, one of these will be the comms room, it measures 1.7M x 0.9M, has a slanted ceiling hence the two separate racks. My plan is to have both a feed and exhaust for the MHVR system into this comms room for cooling.

Utility and hide it in a wall cupboard. Pretty sure regulations prevent it from being directly above a toilet/cistern.

keystone jacks use RJ45 termination and enable stranded cable to be use for structured cabling. It still shouldnt be used for POE applications. use solid core cables and punchdowns for both patch panel and wall sockets. fitting rj45's on solid core cables for keystones is a real chore as the solid cores are to big for the pin sockets of the RJ45.

it is voltage drop, resistance and heat related. The switch has to work harder and can be problematic over long runs. IMO a short patch lead being stranded and the structured (in-wall) cable being solid is fine.

regarding the patch panel or not conversation. Structured cabling should be solid core copper, these are a pain to fit an rj45 connector directly to. Solid core copper cables are not great at being bent, wriggled, plugged in and out ect and can break the core in doing so. You should use solid core copper between the patch panel and the wall socket, and stranded cable as "patch" leads to the switch and to the end device. POE devices should run over solid core cables for the patch leads and the structured cable. A patch panel is about £30. I wouldn't do a structured cabling install without one.

The ASHP in my quote was a 3 phase 16kw panasonic bi-bloc T-Cap. We have 10kw of solar, and I believe both water tanks had immersion heaters.

We had a quote for a Panasonic ASHP with two hot water tanks, 1 for the master bedroom, kitchen, cloak room, laundry room, utility, the other for 2 further ensuites and the master bathroom.

What electricity outfits did you sign up with to get a meter that supports vector sum. My current supplier has been less than helpful and I could still potentially switch from single to 3 phase and change as UKPN havent started the work yet. I can manage on single phase, but well 3 phase is more power scotty.

You must be in a very fortunate location with 3 Phase smets2 meters that support vector sum. Not available for my install, and maximum demand billing applies.
