@JanetE Very useful information, thanks very much.

I shall continue trying to get in touch with them and see what is said. Standby...

Ah. Maybe that is another Openreach change since Jeremy was connected? I had read something similar but couldn't recall where, hence my earlier question.

@JSHarris Thanks again for the comprehensive reply Jeremy.

Did I read somewhere that BT can't be bought up through the slab?

Good thinking re a cable duct for an future ASHP, I presume the cable couldn’t run down the same duct as the ASHP pipes?

I need to finalise this for our timber frame company prior to them installing the raft foundation (they will also site the service ducts and drains). I understand that mains water needs to come in through a 110mm duct/drain pipe to allow space to insulate the main. I want water to go back out again to a garage and/or an accumulator that I can isolate from inside the house. Can both of these water runs fit in the one 110mm duct, or do they have to have one each? Is there a more intelligent way to do it? I understand that mains electricity can come in via a 50mm duct. Can it also go out through the same duct ( to the garage etc) or do they need separate ducts, one in, one out? What about BT, (we weren't going to bother but nothing else is available and the 5G option using Huawei equipment is starting to look dodgy). I presume that needs its own duct and can't share with the electricity? Finally, as a belt and braces option, I'd like to put a spare duct in for a (potential) future ASHP, or AirCon. Would that be 110mm as well? And how would I seal it in a way that I could reopening at some later stage?

@ProDave Dragging this thread back to life. What was the answer?

I'll pop that in the 'too much information' folder ?

Thats already installed, the squirty soap that is, and has remained unused by the gallant groundworkers for the last week (as has the bog brush).

That was a great idea Russ, it's working a treat. I've used loads of the old bungalow roof timber for the frame, and a bit more to cover the soil pipe so it didn't look too much like a gas chamber (though I'm sure it will feel like one at times...). The plywood manhole cover is in two pieces so that I can lift half without disturbing the soil pipe and check that, er, all is in order. The flower thing had decided to grow in our bomb site of a plot so I dug that up to use it as an air freshner. Oh and a bit of old vinyl flooring to make the slopping out a bit easier. No AAV as yet, doesn't seem to need it but it hasn't really been properly stressed tested yet. I have...

@JSHarris, it turns out the helpful guy has retired Jeremy so no joy there. I spoke to the scaffolders and they are not at all concerned with the telephone cable so I'm going to leave it be and see what sort of problem it's likely to present as the build progresses. I'm not entirely sure if that is the wisest move but it's 'plan A' at the moment...

That's the little gem I need to confirm. ~~~ The Openreach wire affecting us comes from a telegraph pole and goes to an SSE pole and then on to the last house in the lane. I'm pretty sure scaffolding will be all around it if it stays put. Why has it taken me so long to realise this??

That's surprising.

@vivienz that was good news. Our flying wire serves 1 property, here's hoping that Jeremys contact might be able to help out.

I'd read your tale Jeremy. I don't know it that ruse is going to work for us because that would mean digging up many meters of right of way to lay the duct but I'd certainly appreciate the phone number as a starting point, thanks.

Help. I've got on Openreach 'flying wire' that looks like it's going to be very close to the new build. (@vivienz What did happen in the end with your Openreach cable?) We have a 'flying wire' that crosses a corner of our plot, to poles that are outside of the plot, and I reckon it's going to be very close to our new build so basically in the way, especially of scaffolding. I understand Openreach can 'fly wires' over property without Wayleaves providing it doesn't interfere with the 'normal business of the property'. I presume redeveloping the site is 'normal business'. Does anyone know where I stand with this?

@Patrick We've got over 50% timber/composite cladding and had similar difficulties for site insurance. We ended up calling the BIBA (0370 number) https://www.biba.org.uk and they put us through to a broker and within a couple of days had a reasonable quote for site insurance. May be worth a try.

A bit of both really. The shed is built (out of timber from the demolition) The toilet and sink are in (not plumbed yet). The light and water heater were going to lift it from 'posh camping' to 'glamping'.

Actually, that's a very good point. Whilst I'm saying 'temporary' it could be there a while knowing what I know about how slowly I operate.

Good morning all. I've built a little shack at the bottom of the plot that is going to house a WC and sink plumbed into the existing foul drain. I plan on putting a 3kW Triton electric handwash heater and a light in the WC. The temporary WC is 30+ meters from my Temporary Building Supply and to route any cable from the TBS to the WC would necessarily cross the access to the plot. What is the best way of doing this, temporarily?

You and me both!

@TerryE thank you for all that Terry, I'll definitely pin down exactly what is and isn't going to be done by MBC. I recall reading @Stones's comments re the female fitting on top of the risers, a good idea. That is definitely on the 'to-do' list, and maybe 3 of them - 1 for water (in and out), 1 for electric (in and out, bt etc), and 1 for last minute changes of plan! As it stands we don't have an ASHP in the scheme - it was going to be Sunamps all the way but my confidence in that plan is being dented in light of recent developments.

@Pete was that MBC? Did they ‘instal all pipes and ducts’ for you? @Russell griffiths some very sound advice there. Thanks.

I do recall your trials and tribulations with that. Water will be a problem for me as well, not sure how hard it will bite yet.
