No, that's how outsourcing works.

The vendor didn't write the contract themselves. Someone at the DWP made that contract that didn't specify that it should work on the OS/browser combinations that actually matter, and that someone should be fired.

When you write a contract you specify what criteria the contractor must fulfil in order for the contract to be "fulfilled", and hence for the contractor to get paid.

If your contract is so retarded that it allows a website that doesn't work except on WindowsXP/IE6 to be "the finished product" less than a year before that combination leaves service and cannot be used at all within the UK government and isn't used by 90% of the population, then you shouldn't be allowed with a pen anywhere near another government procurement project ever again.
