Does your fuseboard look like this? Does it have re-wireable fuses?

Old Style Rewireable Fuseboard

If so, it should be replaced.
All domestic circuits should be protected by an RCD (trip switch) for your safety, in the event of an electrical fault.
Modern consumer units offer you the safety protection required by the 17th Edition wiring regulations.

Earthing

Is your gas meter and water stop cock earthed?  You should be able to see a large green and yellow striped cable and earth clamp at each point.

Gas Meter With Safety Earthing Bond

If not, this should be done. These earthing cables are an important safety feature of your installation.
Contact us if you are at all unsure if these cables are installed.
