They can’t be arsed so want the easy option. some timber wedged in the web of the beam. Fine for the national housebuilders….

Weld metal plates, drill and tap to suit would be my choice.

Do you have the engineer code to access to alter these features?

https://mcscertified.com/wp-content/uploads/2021/10/MIS-3002_Solar-PV-Systems-V4.0.pdf page 18 looks like 400mm on a pitched roof now unless extra design is in place to prevent uplift

Use a compressor and blow it through rather than a domestic hoover sucking it…

Scottish Water made us use a boundary box for a recent connection the link also mentions other utilities so. It just specific to SW https://store.jdpipes.co.uk/scottish-water-boundary-box-meter-chamber/

Get a ball of string and a plastic bag and a vacuum cleaner. tie string to handle of plastic bag, stuff into duct, go to other end with hoover and suck bag which will pull the string, then pull a blue rope through for cable pulling.

I know I bought the book last year, and contributed to the author for his efforts

Might have been better to screw a timber plate to the angled ceiling then fix the vertical timbers and similar wall plate just like making a partition looks a bit thin on substance.

I’m sure the original MCS rules were 200mm from the ridge on a pitched roof. I would be happy with that, lots of new skirtings/architraves now to prevent bird nesting imagine that will help with uplift

You will need a structural engineer’s input to get sign off for building control purposes

https://heatpumps.co.uk The author has been doing this for 30plus years, some good info, you tube videos etc worth a look

4 days for non reinforced OPC ( ordinary Portland cement) slab watch it doesn’t dry out to quicky with the nice weather we are having watch the edges of the slab they may still be prone to damage

Can’t see a link to see the full spec

He would issue a electrical installation certificate as advised above.

Make sure the concrete is pokered. I can’t find the info, but sure it increases concrete strength significantly. concrete like smooth chocolate or aero bar chocolate I know which I would prefer for strength

what kind of logs? sufficient weight in these to have a deeper perimeter foundation? I’ve been using c35 a lot for work foundations for special columns with fibre additives to save climbing down a 1 m hole and placing mesh on chairs

My local authority-Fife is happy with a copy of the SJIB/JIB card proving competency, no scheme membership required

And they will request a hole of a certain size to make the connection. I would also check with the gas company that the spec proposed for the gas duct is correct. effectively check all the suppliers and their own underground requirements

Make sure you fit 2 single sockets for the washing machine and dryer and not a double socket

If it’s free standing I would allow 605mm internal width for both machines, gives some room for wiggling in and out and some clearance when it goes into Mach 2 spin mode. with appropriate timber support in between, I think 1200mm unsupported worktop is too much

Well over the going rates for an employee https://www.jib.org.uk/documents/publications/182-final-jib-industrial-determination-2022-2023-7-7-21.pdf

I bought a cheap 600 watt inverter from eBay and connected it to a spare 250 watt panel. inverter lives in an IP box, it comes with a plug and this is plugged into a power meter Excluding panel think it was under £100

6mm for me
