Just had a builder round to quote for removing an internal load bearing wall. Told him I want it all done properly to regs etc. and he said that they don't need building control to do the job if they use a Catnic lintel. He said if using a standard RSJ then you would need structural engineers calculations and would then need to go through building control. I questioned this but he said no that is definitely correct. Sounds wrong to me - can anyone confirm please. He also wants to put two new doorways in internal walls without building regs (both brick requiring a small lintel).
Thanks.
Thanks.
