I'm looking to get a water meter installed on my property, as I don't use much water.

My water provider's website says this:
"When installing meters in properties built before 1996, it may be necessary to replace old metal pipes. Some older electricity systems still rely on the supply pipe providing an 'earth' - this is now prohibited. If you believe your property may have this system, you should contact a qualified electrician to ensure you have an adequate earth."

Is it a difficult or easy task to identify whether this may be the case? My house was built in 1938 and still has a very old electricity meter (the kind with clockface dials, not even a 'digital' read-out). Is this something a non-electrician could identify, or would I need to get someone out?

thanks!
 
Yep,pictures of the installation,would assist,but do not always match results of testing.
I tested a rod on one occasion,which gave poor results,and had only been in a couple of years.
The same property had an old,redundant steel pipe entering the property,which had fed an oil boiler,once,from the garden. The Ra of which,beat the rod,by a factor of four.

I also remember several properties in north Manchester,all semis,on one road,which were TN-S,but had sweated solid core singles,to short,roman spear like rods,inserted a few feet away,in the sub-floor space.
