Netflix started as a simple idea: let people watch what they want, when they want, without leaving the house. Spotify did the same thing for music. Both began as nothing more than a concept sketched out by people with no guarantee of success — and both grew into platforms used by hundreds of millions of people worldwide. Your idea for a streaming platform, whether it’s UK-focused entertainment, niche genre content, live events, or something nobody has quite built yet, could follow a similar path. The difference between an idea that stays a slide deck and one that becomes a real business is having it actually built.
That’s where By Design UK comes in. We’re a UK software development studio that sits between hiring a freelancer and signing with a big agency. You don’t need to understand code, servers, or video streaming infrastructure to work with us — you just need the idea. We handle the rest: design, video delivery, subscriptions, payments, user accounts, and the admin tools you’ll need to run it day to day.
Every project is different depending on how many features you need on day one — user profiles, multiple subscription tiers, offline downloads, recommendation engines, and content licensing all add complexity. As a guide, custom platform builds like a streaming service typically fall between £18,000 and £650,000+, depending on scope, scale, and how much of the platform you want at launch versus added later. We agree the fixed price upfront, in writing, before any work starts — no hourly billing, no surprise invoices. You can see the full breakdown of how we scope and price projects on our platform development services page.
If your vision is closer to a content subscription storefront rather than a full custom streaming engine, it’s worth having a conversation — sometimes a simpler build using an existing commerce framework, in the £499–£18,999 range via our Shopify build services, is the smarter first step before investing in a bespoke platform.
Freelancers are often cheap and fast to start with, but a single person building a streaming platform alone means one point of failure — if they disappear mid-project, get overloaded with other clients, or simply can’t handle the complexity of video infrastructure and payments at scale, you’re left holding an unfinished product with no support. Traditional agencies solve the reliability problem but introduce new ones: long discovery phases, vague scopes, opaque day-rate pricing, and months of process before a single line of usable code exists. Neither model is built for a founder who wants speed, certainty, and something they actually own.
By Design UK is built to sit in between. We use AI-accelerated development practices to move at a pace closer to a skilled solo builder, but with the structure, accountability, and technical depth of a proper studio. You get a fixed price agreed before work starts, a working platform rather than a pitch deck, and full ownership of the source code when we’re done — it’s yours outright, not licensed back to you.
We’re not asking you to take that on faith. Tackly.co.uk is a live, multi-toolkit platform we designed, built, and continue to run ourselves — real infrastructure, real users, real uptime, handling the same category of challenges a streaming platform faces: accounts, subscriptions, performance at scale, and ongoing feature development. It’s not a case study written after the fact; it’s software you can visit right now. That’s the standard we hold every client build to.
A streaming platform isn’t a one-off deliverable — video encoding needs, content libraries, and user demand all change over time, and things occasionally need fixing at 11pm on a Friday. That’s why we offer ongoing support plans, starting from £797/month for custom-built platforms (or £299/month for Shopify-based builds), covering monitoring, updates, bug fixes, and incremental feature work so your platform keeps improving after launch instead of quietly rotting.
We’re a UK-based studio operating out of Office 13, 25 Mollison Avenue, Enfield, EN3 7NJ, and every engagement starts with an honest conversation about what you’re trying to build and whether it’s realistic at your budget. Read more about how we work on our about page, or get in touch directly via our contact page to talk through your idea.
No. Most of our clients arrive with an idea, not a technical spec. We translate what you want into a working platform, explaining decisions in plain English throughout the process.
Yes. Full source code ownership transfers to you on completion. There’s no licensing arrangement or vendor lock-in — the platform is genuinely yours.
Timelines depend heavily on scope. A focused first version with core streaming, accounts, and subscriptions can move faster than a full Netflix-style feature set, thanks to our AI-accelerated development process. We’ll give you a realistic timeline during scoping.
That’s a much smaller and cheaper project, often built on a commerce platform rather than custom infrastructure. We’ll tell you honestly which route fits your goals and budget rather than upselling a bigger build than you need.
