suspect wiring


Need some answers to talk to an electrician.

Story
Had my "new" house built eight years ago. Haven't had any major electrical work done since then. Two weeks ago was having air conditioning installed. The contractor said the original wiring of the switchboard was "illegal" or defective and couldn't finish wiring the air conditioner to the switchboard.

Problem
From what I can understand the switchboard doesn't have a main power switch and the main feed is wired straight into one of the RCD switches.

The installer wrote in the defect section of the Electrical Safety certificate:
" No main switch.
1 Power and 1 10ACombo RCD main feed from main supply
no point of isolation except from Western Power Main fuse"

I called the home builder (large company) They said the warranty had expired after six years but being "good guys" they had contacted the original electrical company. The electrical company that installed the wiring are sending a supervisor out tomorrow. He said the rules and regs changed a few years ago and it might be legal/safe.

Questions
Are all switchboards required to have a main switch?
Is this a new reg (less than eight years old)
Is it Ok to wire the mains feed into a 30A RCD?
Can a building company fob you off under this warranty period claim if their wiring was inherently unsafe?

Thanks for viewing

Are you in the UK?

Terminology used in your post suggests that might be your location. It is always helpful to know your location when determining how to answer your inquiry ....
