Top Tech Startups in England, United Kingdom in 2026

At ClearWatt, we’re building the platform that helps people buy, sell and own electric vehicles with confidence. One of the biggest barriers to EV adoption is uncertainty. Buyers don’t know the true condition of a battery. Dealers struggle to communicate vehicle performance. Fleets and leasing companies lack the insights needed to make informed decisions. We’re solving these problems using real-world vehicle data, advanced analytics and AI. Our platform transforms complex EV data into simple, trusted insights. Today, our technology helps consumers understand battery health and real-world range, supports dealerships in selling used EVs with greater confidence, and enables fleets, leasing companies and automotive partners to make smarter decisions. We’re already working with some of the UK’s leading automotive, fleet, insurance and energy organisations, and we’re growing quickly as demand for trusted EV data continues to accelerate. Our mission is simple: remove uncertainty from electric vehicle ownership and help accelerate the transition to cleaner transport. We’re a small, ambitious team that moves quickly and takes ownership. As an early member of the company, you’ll have the opportunity to make a meaningful impact on the product, our customers and the future direction of the business. We value curiosity, initiative, pragmatism and a willingness to get stuck in wherever needed. If you’re excited about technology, sustainability and building products that solve real-world problems, we’d love to hear from you.

deltaflare is the category leader in protecting critical national infrastructure from cyber attack. The power grids, water networks, and transport systems that keep the country running were never built for a connected, adversarial world; we make them defensible without ripping them out and starting again. Defending the systems modern life depends on: power, water, transport. Our platform, phoenix, gives infrastructure operators centralised command over the security of their operational technology (OT) estates: thousands of distributed, often decades-old assets that legacy IT security simply cannot reach. Operators dial protection to their own risk appetite, scale it across the fleet, and stay compliant with sector regulation, all without costly upgrades or downtime. The threat is not theoretical. State actors and criminal groups are actively targeting CNI, and the consequences of failure are measured in blackouts and contaminated water supplies, not lost data. That is the problem we exist to solve. Why it's exciting to work here (optional section, recommended for Wellfound) We are a fast-moving team building genuinely hard things at the intersection of cybersecurity, OT, and AI-augmented engineering. The problems are real, the stakes are national, and the work ships to operators running infrastructure people rely on every day. If you want your code to matter, this is where it does. A few notes on the changes. I've led with stakes and mission because that is what converts a passive browser into an applicant, and saved the technical detail for the second paragraph. I've cut "SaaS-based cybersecurity platform that provides centralised control over cybersecurity" since it repeats itself. I've also corrected phoenix to lowercase throughout and removed the em-dash, per house style.

Stratex Analytics is a sports technology company using data and AI to improve the development, visibility and progression of grassroots football players. Our goal is to give grassroots football better tools, better evidence and better opportunities. We believe talented players should not be overlooked simply because their information is scattered, unstructured or difficult for scouts to access. ScoutLink is our core product and the first of many. It helps coaches create stronger player profiles, gives scouts a faster way to discover suitable players, and helps players and families benefit from a more professional record of performance, development and potential. We are building products that make grassroots football more connected, more data-informed and more accessible, without taking away the human judgement that makes football what it is. :soccer:
