Yes very easy job.
Assuming you will be getting someone in to do it and what area you live in, I would estimate £80-£100 for the glass and £60+ for fitting and disposal of the old panel.
Take some rough sizes bear in mind glass will go about 20mm behind each bead (so bead to bead +40mm for rough sizes) then pop around to some local glazers/double glazing companys asking for a quote.
To be honest at £115 if that includes a side panel, Checking the size and fitting as well Id just let them do it.
Would you have a vehical big enough to transport the glass if you do it yourself? I suspect their supply and delivery price wouldnt be much cheaper as it would only take the guy 20-30 mins or so to do it while he was there.
