Hi: Have you tried http://www.homespares.co.uk ? They do a range of Ariston elements & if they dont have it in stock can usually supply pretty quick & a lot cheaper than £60.00

Have both the sections gone?
You could measure the old one up, then have a look at http://www.elementman.co.uk/index.htm
You should be able to sort something out from all that info. The Whirlpool ones might be a good place to start. Get the original part no of one that looks similar and you can then shop around. 😉
