Purple Roofing first engaged CALLANN after being let down by a larger bid provider. The outputs had not delivered value and no wins had been secured, so the priority was clear: raise bid quality, remove the stress from the process, and create a reliable approach that would stand up in competitive procurement.
From the first Teams meeting we took a different approach. We had already reviewed the tender documents, so the conversation was practical and focused on what would score. We asked the right questions early, cut out the fluff, and shaped Purple Roofing’s responses around their real strengths and the buyer’s pain points, with a clear, evidence-led method that made the submission easy for evaluators to follow.
Our delivery model is designed to support the client, not add to their workload. That means short, purposeful touchpoints, structured information capture, and strong drafts that come back ready for quick approval, rather than pushing writing and repeated reviews back onto the client. As the working relationship has developed, each tender has become more efficient because the evidence base and standard content have strengthened with every submission.
The impact has been immediate. Purple Roofing has achieved a 100% success rate to date, including wins where quality was the deciding factor, demonstrating that a strong, well-presented quality submission can move a bidder ahead even when pricing is not ranked first.
CALLANN continues to support Purple Roofing across individual contracts and frameworks in the North West of England, including:
“I knew it! The quality difference between the previous bid company and you was clear to see, and this just shows it. 3rd place on pricing, but romped it to 1st with the quality. Thank you so much for this, look forward to the others returning based on this result Director, Yorkshire Roofing Contractor
