How much does it cost to replace glow plugs?

How long will it take and how much will it cost, on average, to replace the glow plugs on my Saab 9-5 1.9 TDI?
It will depend on who actually changes them, i.e. a local garage or dealership, plus where they are purchased from. Cost of four could be around £50 - £60. Labour could be up to two hours, but be aware that whoever is to do the job knows exactly how and what they are doing as a sheared glow plug can turn out to be very expensive.
