Upgrading your fuseboard from an old style fuseboard has many advantages.The first & foremost is from a safety aspect. If you have a fuseboard that utilises rewireable fuses or has no Rcd protection then you will certainly benefit from having this work done.
An old style fuseboard usually means that you will have limited protection from serious electrocution if something should go wrong. If you need to have any additional circuits added at any time to your home for an extension, additional sockets or an electric shower etc, you will have to have these items added to a seperate board that incorporates Rcd protection which in turn adds to the cost of having these jobs done. A new fuseboard should have spare capacity available for this type of addition. Just the convenience of flicking a switch instead of fumbling around with fuse wire is a major benefit in itself. The safety features of protecting you and your family is the major reason for having this essential work done.
