Hi,

A bit of advice, and maybe a bit amusing. 

I have had our lightning protection systems tested recently, and it passed as expected, but I then received a quote from the same people stating that there is no surge protection on the main LV panel.

They didn't have access to it, its in the powerhouse, fed by a 1MVA transformer, but they have actually quoted £1,350 for a type 1 SPD to the main board and one SPD to the fire alarm. I know they have just sent this as a standard sort of touting for business thing, but it did make me wonder if there is actually any requirement to retrofit SPD to our existing installation

Any thoughts?

Thanks
