I am considering moving house shortly. An electrical report supplied by the vendor (from 2009) has a note from the electrician saying something about the "Earth Loop Impedance" being too high (I think it said 0.58ohms). There are also copies of follow-up letters from the local distribution company (YEDL) indicating that this is "normal" due to the design of their network in that area.
The house is a fairly isolated 4 bed detached farmhouse style property (about half a mile from the nearest other houses) . It has a single-phase "PME" supply. My surveyor indicated that the main consumer unit is probably less than 5 years old. Other than the usual cooker, lighting, and socket circuits there appears to be a larger separate outdoing circuit from the consumer unit (via a single 60amp switch) to a smaller consumer unit in an annex.
Can anyone help with these questions:
1) Is this high reading anything I should worry about really and what are the day-to-day implications (if any)?
2) Is this issue likely to restrict anything electrical I would want to do with the property in future? For example:
a) install solar panels
b) fit a large heat-pump (max size that would work on single-phase supply)
c) install a power supply to a new external workshop
Thanks in advance,
Shaun.
