"Building control will want a structural engineer to provide drawings , calculations and design. its not just the steel its also the padstones sizes. He will back his design with his indemnity insurance . So you will need a structural engineer depending on the complexity of the works depends on his costs. Allow £400-1200 for a domestic project"

"You will need the structural calculations for the size of steel and pad stones also if the walls have adequate foundations for point load"

"An experienced builder can put steelwork in but to satisfy building control or private surveyor you would still need a structural engineer to do the calculations and submit them. ( Size of steels, padstones etc.)"

"A competent person will assess the job and if needed would ask a structural engineer for further advice , you don't need a structural engineer unless you want the correct paperwork for the building inspector , but the work can be done to correct regulations by firms like ourselves. Always remember if selling your house in years to come,a prospective buyer may want to see the paperwork"

"If they know how to do the calculations then yes

I always allow for a bigger beam than usual myself

* The question you should be asking is what size beam is required

* Measurement of length and height of wall above the steel

* And having a general idea of how much roof area/ weight is bearing down onto that wall and type of roof tile

This knowledge comes with years of experience and good old know how to install I've been in renovations for twenty three years"

"As long as they know what they are doing it’s fine,the only issue you have is,if don’t go through building control it will void your house insurance which in my opinion I wouldn’t take this risk.

It’s worth having structural calculations and drawings and doing things the right way god for bid something went wrong you would be covered.

And remember old building,houses are not like modern day your find footing are so shallow they might not be able to support the weight and might need to have pad stones fitted to support the steels."

"If you are simply replacing a lintel then yes with no problem, if you are inserting a steel to a load bearing wall then a structural engineer would be required, building control would also have to be notified."

"It’s not recommended and you cannot do without structural engineer calculations about the steel size according to load bearing"
