Approved doc S arrived 15th Dec

Thank you Jon. Interesting reading!  Introducing cost caps is a minefield. Where we are, BC fees are based on the project cost, needless to say, there are perennial arguments. I can see the bean counters and QS guys doing better than the sparks!

where did the £3600 and 7% come from, I wonder?

You'll never know the math behind those figures.

Some weird modelling. Garbage In Garbage Out.

The infrastructure for EV's is now law and it's not going to be cheap.

The network infrastructure cost upgrades will exceed the £3600

Even if it exceeds £3600/7%, I read it as provision for cable routes need to be provided. What does that mean? A spare way in the DB, and room to mount an adaptable box, so that a SWA cable can be put in later? Or, a cable already in place? I'd say the former. 

As said above, Large Building Companies will be getting their Accountants onto it , so that they do not have to provide an EV point. This, to me, shows it is poor Legislation. IMO, It should be mandatory to provide it, and also PV panels, why aren't they mandatory on new builds now?

PV Panels, wind turbines, battery storage room, Hydrogen storage depot.

All to highly subsidised to become main stream.

I take it to mean that ducting or some other form of containment must be provided. The cables and EVCP can come later.

I must admit having tried to read it after a second night without much sleep, new rescue dog. I think the lawyers will have a field day. It is even worse than the wiring regs but much shorter.

WhIle finding Part S I found Part R High Speed coms. Even more complexity. 

Given Building Controls lack of enforcement of Part P and the numerous new houses built with major faults can we expect these new requirements to be met in the same way?

It strikes me that all that is required is to give all the parking spaces around block B to flats in block A and vice versa, and the developers are absolved of any need to provide anything at all. I'd be surprised if this has not occurred to others as well. At current funding levels I cannot see local authorities having the manpower or the will to do more than accept a letter saying' we looked at this and its too expensive'  if developers wish to wiggle out.  It may be buyer pressure rather than anything that drives charge points to appear as developers wish to drive up the asking price of houses - or not.

AD R has been around for 5 years so I assume we have all noticed it's impact already (no ? me neither really) given the impending copper line switch off, it would be more relevant to require a location for a small UPS to keep the phone line and internet up if there is a power cut. As storm Arwen recently revealed, a power cut soon means no comms at all these days if you have fibre to the house.

For part S, the bare minimum is cable routes to charge points , so burying some spare lengths of soil pipe with ropes in  from driveway to meter cupboards will probably be as good as it gets in a lot of lower end places for now. Far more worrying to the typical occupants will be next years leccy bills.

Although there will likely be market pressure to provide charge points ... EV sales are rocketing those with an EV aren't likely to buy a new property if the developers have skived out of providing a charge point.

That's a valid point, but, with the large house building Companies, everything is done to a price, if something is 10 pence cheaper, they will pick it. For example, they only just meet the requirements for insulation now (and, many houses do not, as the workers skimp on it), if they spent a further £1k to 2k more on insulation, the houses would be reaching super insulated standards, not passive house standard, but a very good level could be achieved with a <1% increase in material costs. That cost would pay for itself in less than 5 years of heating bills, yet they don't even think about doing it, they just specify the bare minimum, as it is cheaper.

It is happening with electrical installs. I was at a £350k house last week, 6 months old. No SPD. A minimum of sockets through the house , that's what I was there for, to add extra sockets, as the design was so poor, where the TV would naturally go, there were no sockets in that corner.

If there is a way of reducing costs, the House Builders will do it.

Correct me if I am wrong. Take a new four bedroom dwelling which in some Council areas may require four car parking spaces. These would be associated with the dwelling. The requirement then is at least one of these must be provided with a charge point unless the supply cost would be more than £3600 above the cost of the required supply to the dwelling had the charge point not been required. If the cost was £3601 then the requirement is for a cable route only. The other three associated parking spaces do not require attention, at least according to Part S.
