C3 outcome on ‘4.18’ from EICR (“No RCD for some circuits”)

Hello I recently had an EICR done at a rented property. All pass except a C3 outcome on ‘4.18 RCD(s) provided for fault protection...’ comment being “No RCD for some circuits” and therefore recommended for improvement. The EICR issued is also recommending next check in 3 years (reason for not 5 years given by company: engineer likely put is due to no RCD for some circuits). Report Summary:- Extent of report: Electrical installation. Consumer unit, Sockets Circuits, Lighting Circuits, Cooker Circuit and Bonding. Fixed Wiring Only. 10% of circuits where accessible. Limitations: Tested in accordance with GN3 table 3.4. Tested in accordance with GN table 3.3 for inspection and 3.4 for testing. Limited dismantling. Erection methods only visually verified. Zs testes done at all accessable sockets and lightning points. 10% of circuits where accessable in accordance with GN3 table 3.3. Cables are secured and torqued against manufacturers instructions. Is it plausible for the above scenario validate an EICR for only 3 years, or would other factors come into play? Also, is it a requirement for all circuits to have RCD otherwise a C3 rating is given? Presume no RCD is referring to the first 6 MCB circuits in the consumer unit (or specific circuits from these 6) that are not RCCB controlled. I don't think any of these MCB circuits are wall sockets - not sure if this is relevant. Also, what are the various options for improvement? Many thanks in advance, H
