Poorly Tree

I thought it was a Montanery Pine

Give it LOADS OF WATER

Your tree is a "cut out" Norfolk Island pine. It's a mediterranean variety that needs high humidity and isn't as hardy as the varieties we grow outside in the UK.

Thanks everyone for your help. Knowing the name has enabled me to read up on it. We have just bought the house and I think we now need to check the watering system? I think it was probably suffering from lack of water.
