Somewhere around Ł120 labour would be average for a proper chippy, specialist loft installers will usually charge more, there are a lot a variables on the materials depending on what you want.
High ceilings, awkward access, above staircase or lath and plaster ceilings might knock the price up a bit.
Its not a bad job for a handyman but he'd take longer than a proper chippy so its swings and roundabouts depending how cheap he is.
