In simple terms any Barnett allocation is based on the following

So for example, a £1BN increase in HS2 budget would lead to a £1Bn increase the DfT budget, on the basis of the above CF then the Barnet allocations are approximately:

Scotland             = £1Bn* 92% * 10%        =  £92M

NI                        = £1Bn *95%  * 3%         =  £29M             

Wales                 =£1Bn  *36%  * 5%         = £18M

 

Applying that process to  the entire £108BN allocated to HS2 on the same basis as a change to DfT budget

Scotland             =  £9.9Bn

NI                        =  £3.1Bn

Wales                 =  £1.9Bn

 

One could apply the same to NR Enhancement funding which is calculated the same way as HS2
