Following a new supply pipe from the road mains being fitted my water pressure is now too high. I have a Worcester Combi boiler and sep elect shower. What incoming pressure do I need at my main tap please. I have a DIY pressure guage on its way at the moment, can I regulate the pressure by turning down the new main tap in the road.

i doubt the guys on here would recommend tampering with the main stopcock, on the other hand they may suggest a pressure reducing valve which i think will keep the pressure down to around 3.5 bar, which is pretty standard.
Turning down the stopcock makes no difference to the static pressure of your water supply, it just reduces the maximum flow rate.
Partly opening the stopcock can damage the valve seat and washer, so it won't work when you need it to.
What is the problem(s) you are trying to solve by reducing the pressure

The problem is that my wife is drenched every time she turns on the kitchen tap ! Seriously though, during the recent cold spell I had what I thought was a pipe burst in the out-side laundry room. I turned off the supply for the time assuming it was due to frost etc. On looking to fix this I now find that the new pressure seems to have blown the pipes away from the sink fittings.

...after the main stopcock in your house
more likely the ice inside the pipe
I used to have very high pressure off main which is 7.6bar, and keep blowing / split electric shower 3 time. I have fitted a pressure reducer valve, with gauge showing what pressure is it, and set it to 3 bar. I had no problem so far. It also help reduce flow noise.
If you need it, fit it after main stopcock.
