Is professional installation worth it?

A standard 8x6 shed is a half-day job for two reasonably practical people with a drill and a spirit level. Larger buildings, log cabins and anything with heavy glazing are a different proposition.

Pay for installation when

• The building is over about 10ft x 8ft, or uses 28mm+ interlocking logs.
• Panels are too heavy for two people to lift safely.
• The building includes large glazed units.
• Access is difficult and materials must be carried through the house.
• You want a workmanship guarantee on the assembly.

Check what is included

• Base preparation is almost never included — you must have it ready and level.
• Removal of packaging may be an extra charge.
• Treatment and painting are normally excluded.
• Confirm whether the fitter will position the building precisely where you want it.
