ᐅ Is an Additional Circuit Breaker / RCD Really Necessary for a Home Office?

Hello!

I need to ask again because we have very little knowledge about electrical work. I’m not sure if our electrician is overcharging us or if these additional costs are necessary and reasonable.

We have planned an office where we want to set up 2 gaming PCs. Originally, we planned for 18 power outlets there (just to have enough), but we are now reducing that to 8. For each PC, we will probably need a power strip (1 computer, 2 monitors, possibly some small devices like a label printer).

The electrician says:

• We need a separate circuit for the office: 150€
• A separate residual current device (RCD) / ground-fault circuit interrupter (GFCI): 115€
• And because we get an additional circuit and RCD/GFCI, we also need a larger distribution panel: 490€

All prices are excluding VAT.
Can it really be true that this creates a chain of costs like this? Is it necessary?
He says that if we don’t do the separate circuit and RCD/GFCI, we can save on the larger distribution panel, but then we wouldn’t be allowed to use power strips there (which he says would be a major fire hazard).

I’m surprised because we have run exactly this setup in our current house (30 years old, with only one RCD/GFCI for everything) for almost 10 years without any problems (or fires). Are we risking our lives every day for years, or is the truth somewhere in between?
I’m not sure what to do here right now.
