That looks like a metal enclosure? Hager RCBOs are about £15 a pop, so about £150 for parts. Can anyone see why it shouldn't be upgraded rather than replaced?
As a cheaper option I'd agree you would at least get type A RCD protection with minimal disruption.
For about £150 more in parts you could have surge protection and RCBO's that switch the Neutrals too (Hager's don't) giving better isolation of future faults.
