Our Work

Case Studies and Testimonials from clients


Everyone in The Winning Proposal team has decades of experience under their belt. Before joining us our people were the top Bid Managers, writers and consultants in the organisations they previously represented.

Why is this relevant? Because so often companies that claim to be able to help you bid better and win more haven’t always been round the block themselves.

If they haven’t faced the challenges that you are currently facing, in the markets and sectors in which you operate, how can true value be brought to your proposals?

We pride ourselves on the quality of our work and that fact that our clients ask us back in to help them time and time again.

But don’t just take our word for it!

Here’s what past and present – and in all likelihood future – clients are have already said about the proposal and presentation services we have delivered.

“In six weeks they helped grow our funnel by £65m, £31m of which became closed business within four months – a fantastic achievement!”
