More than likely although there are still circumstances even on new installations were a socket circuit does not need RCD protection. Remember in TN systems the RCD is only there for additional protection. RCD's are not the be all and end all, do you know how many would fail proper testing.
Back to your op, so long as the installation complied to the version of BS 7671 in place at that time and is still in a serviceable condition then there is no need to upgrade.
