At PSS (Perfect Support Services), we’re not just another R&D tax relief consultancy. We’re a close-knit team of financial, technical and industry professionals committed to doing things properly - and that means delivering legitimate, fully compliant R&D tax claims that genuinely help UK businesses grow.
Born out of a frustration with misleading practices in the market, we built PSS to offer a better alternative: expert guidance, clear communication, and zero shortcuts.
To deliver technically robust, ethically sound, and client-focused R&D tax solutions that empower businesses to innovate and grow with confidence.
To be the UK’s most trusted and innovative R&D consultancy, recognised for our technical excellence, integrity, and ability to drive sustainable client success
PSS was founded by Rob and Ranjan - two experienced professionals who recognised the need for a consultancy that prioritised client care and compliance over quick wins. Since then, our team has grown in size and strength, combining chartered accountants, industry experts, and project managers with a shared goal: to help businesses claim what they’re entitled to - and nothing more.
We’ve supported companies across software, construction, architecture, engineering, manufacturing, pharmaceuticals, farming and beyond. And we’ve done it without inflated claims, unethical practices, or hidden fees.
At PSS, we don’t rely on shortcuts or overselling. We’ve built our reputation - and our results - on doing the work properly, honestly, and with purpose. These six pillars guide everything we do, from how we assess a client’s eligibility to how we support their long-term growth. They’re not buzzwords. They’re how we do business.
