Hi @gaz108
Welcome to the community.
The Bluelight discount would only be able to be used on brand new contracts, and not on upgrades.
Who is it you work for? If it is a employer who is part of our Perk scheme, you may be able to get a discount code that can be used on eligible upgrade plans. The Perk discount gives you up to 5 codes to use each year, which can be given to friends and family members.
