You can spend a lot on kitchen & bathroom upgrades on a 1930s semi or very little. Which one is right depends on measurements, not on the quote. The scope is standard once the physical routing is planned around that construction. The practical question for a Caerphilly property is not what usually happens, but what this installation actually shows when it is tested. Focus on the porch is the part worth confirming rather than assuming.
The regulations move; installations do not. Part of the job is explaining which differences actually matter and which are simply age. Which is why the price follows the test rather than the other way round. Kitchen & bathroom upgrades on a 1930s semi sits somewhere between routine and urgent depending on what the property is doing right now.
