Yes Harminder it does sound quite simply that your element requires replacing on the oven, when i carry out this kind of repair i also replace the Thermal Cut Out also known as a TOC at the same time as these can also go at the same time as the element. The category you require is the Electrical one and im sure a local tradesman will be able to help you out. The cost of the job would depend upon a number of issues - 1. Make/Model of Oven, 2. Is a Genuine replacement spare required or would an equivalent part surfice. The replacement would take no longer than an hour at the most and cost depending upon the above factors shouldn't cost more than approx. £150 in total. I hope this helps in some way.
