Any additional works have to meet the current regulations. this means that the sockets you wish to add must be rcd protected. if your consumer unit doesn’t have rcd protection then there is a couple options available to you.
you may be able to get an rcbo that will fit into your existing consumer unit which will suffice as the circuit being worked on will be rcd protected.
you could have a new circuit wired from a new rcd enclosure
or you could have the entire existing consumer unit replaced but before you consider replacing the whole consumer unit i would recommend that you have an electrical installation condition report carried out as this will highlight any issues you may have within the electrical installation. if you don’t have this done first then you could end up having issues with the the rcd’s and nuisance tripping due to an underlying issue and any faults highlighted once work has already started will have to be rectified before you can get the work signed off and a certificate issued.
hope this helps a little

Hi this will all depends on who you get to undertake the eicr but i generally charge £120 for an eicr.

The cost of replacing a consumer unit varies. it all depends on how many circuits there are, if the water and gas bonding require upgrading and what protective devices are being used in the new consumer unit.
our regulations have changed and now we are required to install consumer units with surge protection in addition to the rcd protection that was required before. this has added additional costs to replacing a consumer unit as you can imagine. i am from leeds so the prices up here are a little less than down there but here is a breakdown of how i’d price the works to give you an idea
eicr (to be carried out first to highlight any issues) £120
materials to replace consumer unit £280
labour to replace consumer unit £160
upgrading of main gas and water bonding (if required) £150
obviously these prices are an estimate due to not seeing the property but hopefully this will give you an idea
