Warranty Solutions Group (WSG) has partnered with Genome Design Ltd, an independent Porsche and supercar tuning specialist, to introduce a new warranty programme tailored specifically for modified Porsches.
According to a press release, the initiative is aimed at providing tailored cover for high-performance, customised vehicles, addressing a long-standing gap in the warranty market.

According to WSG, the programme has been designed to accommodate the nuances of aftermarket enhancements, such as ECU and TCU remapping, without compromising warranty support.
Genome Design, based in West Yorkshire, is known for precision-led Porsche modifications that combine bespoke software calibration with high-quality hardware. The firm’s director, Nick Cook, said the partnership helps “legitimise” vehicle customisation, which he described as “a lifestyle choice” driven by “identity, innovation, and community.”
The move comes as the UK’s aftermarket sector continues to grow, fuelled by a rise in vehicle personalisation and new technologies. According to industry estimates, the UK automotive aftermarket is projected to exceed USD 19 billion by 2030.
WSG’s Group Director, Steph Newbery, said the collaboration reflects a shift in how modified vehicles are perceived within the industry. “For too long, modified vehicles have been excluded from warranty policies,” she said. “Our goal is to support the evolution of the aftermarket and help ensure modified cars remain roadworthy, insurable, and warranty-compliant.”

By GlobalDataNewbery noted that the growing popularity of EVs, online customisation communities, and sustainable components is reshaping expectations around personalisation and reliability. “The lines between OEM standards and aftermarket innovation are blurring,” she added.
Genome’s performance builds, often inspired by motorsport and engineered for reliability, have gained attention from a younger generation of drivers seeking both performance and individuality. Cook highlighted the influence of platforms like TikTok and YouTube in bringing modified cars into the cultural mainstream.
As the global modification market trends toward an estimated USD 70 billion valuation by 2029, partnerships between warranty providers and specialist tuners are expected to play a growing role in supporting innovation while ensuring consumer confidence.
