Get the LPG conversion kit for this hob from Neff(www.neff.co.uk) or contact a Neff dealer in your area to order one and supply to you. Get a Calor Gas main dealer or Gas Safe installer that to install and set up the LPG conversion kit for you(if you go to www.calor.co.uk and click on calor dealers and enter your town/postcode you'll find a dealer in your local area that could help you;these are identified by a cooker servicing symbol, or if you don't want to approach a Calor dealer, look in the phonebook for a Gas Safe installer who handles LPG installations and servicing), don't try it yourself. Most propane regulators in the UK are set for 37mbar pressure;this should easily power your cooker/hob/oven, there are also some regulators at 50mbar for propane these are mainly used in caravans.
