IoT · London

IoT Software Development Company in London, built to ship.

A sensor reading is worthless if it arrives too late to act on. Our IoT platforms move data from device to operator insight in milliseconds, handling provisioning, real-time telemetry, edge processing, and operational dashboards inside one connected system. The architecture is built to grow from a hundred devices to a hundred thousand without buckling. We have done it at fleet scale. London (GMT, or BST in summer) sits 5.5 hours behind India (IST), which is the most convenient overlap of any major Western market because your morning is our afternoon and the two working days share a large chunk of live, productive hours.

London market

London is Europe's leading technology hub and ranked third globally in Startup Genome's 2025 ecosystem report, with UK tech raising 12 billion USD in the first nine months of 2025. Its fintech sector is the strongest in Europe and second only to the United States, which keeps demand high for custom software, payment platforms, dashboards and mobile apps. Geminate Solutions acts as the remote product and engineering arm for London founders and businesses that need to move quickly without overstretching local hiring budgets.

Local signal: The UK tech ecosystem recorded 12 billion USD in funding in the first nine months of 2025, with London's fintech sector confirmed as the number one fintech hub in Europe and second globally.

FAQ

IoT Software Development in London, answered

Which IoT protocols and device types can you support?

We support MQTT, CoAP, HTTP and REST, WebSockets, Modbus over TCP and RTU, BLE, and LoRaWAN out of the box. A protocol abstraction layer lets us add new device protocols without rewriting your application code, so mixed fleets stay on one platform.

How do you secure connected devices and their data?

Each device receives a unique X.509 certificate for mutual TLS authentication, so only trusted devices connect. We add device identity management, encrypted channels, secure boot verification, and network segmentation between the device and application layers.

Can you integrate an IoT platform with our existing SCADA or industrial systems?

OPC-UA and Modbus are how we reach SCADA and industrial control systems, plus historians such as OSIsoft PI. That bridge connects existing operational technology to a modern cloud platform without ripping out the equipment you already run.

How much of the working day do London and India actually share?

London is 5.5 hours behind our India team, which gives one of the best overlaps we work with. Your full morning is our afternoon, so live calls, code reviews and approvals happen in real time without anyone working unsociable hours.

Is offshore development with Geminate Solutions more cost-effective than a London agency?

London carries some of the highest developer rates in Europe, so an offshore product partner usually reduces your build cost substantially while keeping delivery quality high. We scope the exact cost on a call once we understand your product, rather than listing a headline rate.

How much does IoT Software Development cost in London?

Every iot project is scoped on a free call rather than sold as a fixed package, and most engagements start with a paid pilot sprint so you see the work before you commit. You get a clear number in GBP before anything starts.

Do we own the code?

Yes, completely. The code, the project, and the content are handed to you. You hold the keys, not us. We sign an NDA before you share anything.

How long does it take?

Most builds go live in two to four weeks. Larger products with a custom backend or migration take longer, and you get a firm timeline before any work begins.
