Check all this with your water company before doing anything! They may replace their lead pipe (from main to your boundary) free-of-charge.

Contact your water board they will be able to advise they will also have to inspect the pipe run before you bury it,about 900mm they will also inspect your current stop cock and and replace it in the road way if nessary. When I replaced mine I found them very helpfull,

Consider getting a quote for getting it moled in before you go breaking your back, you may find it a much more appealing proposition. I have lead pipe aswell but just filter all the drinking water through a RO / Di filter.

The lead for lead policy seems to have been shelved in my area in the interests of private enterprise, they wanted £700 from my recent customer just for their side, so we just joined to the lead as it entered his boundary. No real need to do any more than that in most situations. If your water board do still operate lead for lead go for it.
