If you have wall sockets that sometimes smell of burnings, or plugs with heat damage. STOP using them.
13 AMP single socket overloading is very common in Cyprus due to the use of electric heaters in the winter and high power cooling fans in the summer. Also misuse of the wall sockets by forcing Europeans and Middle East plugs into the wall sockets that are designed for British 13 AMP plug tops only.
Sockets that have overloading damage should be replaced immediately by a qualified electrician only.
Don't not risk your life or the life of others by attempting to replace damaged socket outlets in your home - It is not a DIY job.
