I have just been fitted with a modem for my internet and also had a new phone line put in the same corner as my tv, set top box , router, dvd, video etc. etc. So need 2 new plug points-I have a double socket in that corner and run 2 multi extension cables from them - one holds 3 plugs and one holds 6. My question is are these extension boards quite safe even at full capacity or should I get a new double socket put in the corner? Advice from an electrician would be appreciated to put my mind at rest.
