As said oxy-propane is easier for home use. Difficult to get hot enough for welding and cutting but perfectly adequate for heating and brazing.
Adams Gas do hobby cylinders of oxy and deliver/have stockists across most the country now. Hobby bottles aren’t filled to full pressure and you will use a lot of oxygen with propane.
If you have the cash now look to get a recon oxygen concentrater. They are around £300 but that is only 8 fills of the oxy bottle (even less if you take the deposit into account)
The oxy propane kit from Weldequip is excellent and well priced. If you do go for oxy-propane make sure you get the specific (red) propane hose as propane will damage an (orange) acetylene hose.
