About MyUtilityTools UK & Systems Engineering
MyUtilityTools UK is an independent computational portal engineered specifically for British taxpayers, home buyers, mortgage holders, clinicians, and engineers. Our mission is to provide transparent, statutory-verified, and privacy-first calculation engines that run with sub-millisecond execution directly in client memory.

David Miller is a senior software engineer and systems architect with over a decade of experience in client-side software engineering, mathematical modelling, and accessibility compliance. Prior to creating MyUtilityTools, David designed financial data pipelines and high-volume transaction interfaces.
At MyUtilityTools UK, David oversees core algorithmic design, cross-browser IEEE 754 precision compliance, and continuous synchronization with HM Revenue & Customs (HMRC), the Department for Work and Pensions (DWP), and the National Health Service (NHS) statutory guidelines.
Architectural Principles: Zero Tracking & Local RAM Processing
Modern web utilities frequently transmit sensitive financial and personal details back to centralized servers for analytics, profiling, or lead generation. MyUtilityTools UK rejects this paradigm. Every calculator hosted on this portal operates on an uncompromising 100% Client-Side Architecture.
When you calculate your Stamp Duty Land Tax, model mortgage overpayments, or calculate statutory entitlements, your numbers never leave your browser sandbox. The calculations execute directly within your device’s volatile memory (RAM) using native JavaScript mathematical primitives.
Cross-Platform Compatibility & Screen Reader Testing Matrix
We believe statutory tools should be universal. Every tool undergoes systematic automated and manual testing against major screen readers, assistive platforms, and viewport constraints:
