Can you Capitalise Data Warehouse Costs

I am currently working as a Capital Accountant & l have been asked by my boss whether the  Data Warehouse Costs are Capitalisable

The majority of the costs are made up of 400k over 3 years of external consultancy fees & some Internal Management Costs of 200k over 3 years

Software Costs of £100k.

The whole project is really to integrate  data across the organisation and improve the speed & accuracy of reports.

My boss is of the idea that we can capitalise the whole lot as project costs.My view is that we can only capitalise software costs. Another thought is to capitalise in line with IAS 38- development costs but l am not sure.
