The GDS is one of the more credible parts of government IT in the UK and IME generally well respected. The government websites and online services have largely been well done. But there are limits on how much that organisation can take on with the resources it has and it's still subject to the same challenges around compensation and working environment I mentioned in another comment that make it difficult to hire and retain good people. Unfortunately it's not realistic to build all government IT projects in house that way at the moment.
