Truncating Wires in the home and bedding them into the ground

A question about : Truncating Wires in the home and bedding them into the ground

Hoping somebody can advise about this as I'm not terribly knowledgeable about home electrics. To cut a long story short, my family have been moved out the property we own due to flooding and the company doing the work have found the leak and are preparing the drying of the property. Now before they will continue with the repair and restoration work, they have noted that some electrical wiring in three locations will need to be 'truncated' and buried into the ground as this is not the type of work they do (at present the wires are not embedded in the ground and have just been covered up by flooring, assumably by a previous owner of the property, as our home was built in the 1960s and we have owned it since 2006). We've found out that this work will not be covered by our building insurance cover. We do however have British Gas home cover and over the phone today they were uncertain as to whether our policy with them covered such work, and so are dispatching an engineer in three days time to have a look.
So essentially my questions for somebody who may know more about this sort of thing is, how much work will truncating the wires and burying them in three locations consist of, and if possible does anyone know of a ball park figure of how much this work will cost should our British Gas Home Care policy not cover it? Our finances are pretty tight after a cowboy builder ran off with huge chunk of our cash for an extension he was half way through building for us, and we are still paying back the money we needed to borrow to get that work completed, hence we are panicking that this will be another huge amount of cash out of the door! Any help or advice would be greatly appreciated!

Best answers:

• A little more information might be useful. When you say cabling what are they for exactly? Also could you give a bit more information on the existing installation? What sort of floors do you have - wooden, concrete etc etc.
• Need more info. If these are mains cables that are not concealed I can't imagine any insurance or home care policy would cover replacement of them, as they're probably functional.
• If they are service wires that come before the consumer unit, they are for the electricity supplier to deal with. e.g. Western Power, not Eon, EDF, Npower etc
  But as above, more detail needed.
• I think you mean trunking
  To truncate means to cut short or reduce
