You can tell if a wall is load bearing, if it is a double storey property and there is the exact same wall lay out on the floor above then the wall below is a load bearing wall.

If this wall has no floor above but has a loft space, you can check to see in the loft space if there are any trusses or main beams resting on the wall, if not then it’s not a load bearing wall.

No building contractor should ever charge just for information, it’s all about getting a good reputation and potential clients passing your name on.

Hope this helps.

A degree of common sense will allow you to determine some structural walls but it really depends upon the style of the structure of your house ie victorian terrace, semi detached, etc. A common mistake some people make is tapping the wall, hearing it to be hollow and removing what then turns out to be a structural wall- for example a wall in the middle of a victorian house that carries part of the load from the roof.
You can check with your neighbours to see if they have had similar works carried out or have a selection of builders come around and have a look. But ultimately, if you want peace of mind, engage a structural engineer who will be able to advise you professionally. A typical charge would probably be in the region of £100-£150.

I wouldnt worry about whether or not a builder will charge to take a look.Most builders will look for free but even if they did charge it would be a minimum fee and would be insignificant if it turns out that it is loadbearing and you want it removed.If it is you will have to pay for a structural engineer to calculate what is needed to bear the load currently taken by the wall,a fee for building control to inspect the work,cost of rsj,skip and labour for someone expierienced enough to do the work.All of which will cost you more than half an hours time with a builder for advice.

The wall needs to be inspected above ceiling height by removing some of the ceiling, or by lifting floor boards. A charge will be down to the individual builder and if further work is required once the inspection has been done.

depends if you are only asking a builder for his advice,then yes he would charge for a visit,

A good builder should be able to tell you, but as taking a solid wall down is classed as structural you need to notify building control.
If its load bearing, you will also need a S/E to calculate any steels.
