I’m John Mapother, founder of Vantage R&D Tax Consulting Limited.

With an engineering background and over 500 R&D tax claims successfully delivered since 2014, I specialise in turning complex technical innovation into clear, robust, and HMRC-compliant claims. My particular expertise lies in motorsport, automotive engineering, quantum technology, and advanced manufacturing.

I’m supported by Jason Banks, a highly experienced R&D tax specialist who brings a similar depth of knowledge and technical understanding. Whether you work directly with Jason or with me, you will receive the same industry-leading experience, engineering insight, and commitment to building strong, defensible claims.

Our Approach

We created Vantage R&D because innovative engineering businesses deserve better support — someone who speaks their language, minimises disruption to their team, and navigates the increasingly complex compliance demands of the R&D tax system.

Our focus is practical and personal:

• We take the time to truly understand your technical work

• We build claims with strong, evidence-based technical narratives

• We handle HMRC interactions efficiently and effectively

• We make the whole process as straightforward as possible

Our Promise

Whether your project is in motorsport, quantum, automotive, or another innovative field, you’ll receive expert guidance grounded in real engineering understanding, transparent pricing, and a genuine commitment to securing the best outcome for your business.

If you’re looking for an R&D tax specialist who understands technical development and delivers high-quality, compliant results, we’d be pleased to help.
