Platform Engineering in London — Developer Platforms That Scale
Internal Developer Platforms, golden paths, and developer self-service for London’s fastest-growing tech companies.
Stop making developers wait for infrastructure. We build platforms that let your engineers ship features — not file tickets.
Why London Tech Companies Are Investing in Platform Engineering
London’s tech sector is one of the most competitive in the world. From FinTech giants in Canary Wharf to AI startups around King’s Cross and SaaS companies in Shoreditch’s Silicon Roundabout, engineering teams are under relentless pressure to ship faster. But there is a hidden tax slowing everyone down: infrastructure complexity.
The problem is not Kubernetes, cloud, or CI/CD themselves — it is that platform engineering in London companies is typically handled by the same 2-3 senior engineers who also build product features. Developers wait days to get environments provisioned. Every new service requires a DevOps expert to set up pipelines, monitoring, and deployment configs. Compliance checks are manual gates that delay every release.
This creates a bottleneck that no amount of hiring can solve. Senior platform engineers in London command £85,000-£125,000 in salary, take months to recruit, and even when you find them, they spend most of their time answering the same questions from developers instead of building reusable infrastructure.
Platform engineering solves this by building a self-service layer — an Internal Developer Platform — that abstracts infrastructure complexity behind golden paths. Developers provision environments, deploy services, and monitor applications through a portal instead of filing tickets. Compliance guardrails are embedded in the templates, not bolted on as manual review steps.
Signs You Need Platform Engineering
- Developers wait days for environments — provisioning a new staging or dev environment requires tickets, approvals, and manual setup by your overloaded infrastructure team.
- Inconsistent deployments across teams — each team has a slightly different CI/CD pipeline, monitoring setup, and deployment process. Nobody follows the same standards.
- Compliance slows every release — FCA, UK GDPR, and SOC2 checks are manual gates. Developers avoid releasing because the compliance process takes longer than the coding.
- Only 2-3 people understand the infrastructure — if they leave, your entire deployment pipeline is at risk. Knowledge is trapped in heads, not codified in platform tooling.
- Developer onboarding takes weeks — new hires spend 2-4 weeks setting up their environment, learning deployment processes, and understanding the infrastructure before they can ship their first feature.

How Much Time Do Your Developers Waste on Infrastructure?
The average London engineering team spends 25-35% of their time on infrastructure toil instead of product development. Book a free platform review and we will quantify the productivity gains an IDP would deliver for your team.
Our Platform Engineering Process
Developer Experience Audit
We interview your developers, audit your toolchain, and map the end-to-end developer journey from code commit to production. Within one week, you receive a developer experience report with pain points, productivity bottlenecks, and quick wins that can be addressed immediately.
Platform Design
We design your Internal Developer Platform architecture — which capabilities to build, which tools to use (Backstage, Port, custom), and which golden paths to create first. The design is tailored to your team’s size, tech stack, compliance requirements, and growth trajectory. We start with your highest-impact use case.
Build & Iterate
We build the MVP platform alongside your team in 6-8 weeks: self-service provisioning, standardised CI/CD, service catalogue, and your first 2-3 golden paths. Real developers use the platform from week 3 — their feedback shapes every iteration. We do not build in isolation.
Enable & Evolve
We train your team to maintain and extend the platform, write documentation, and establish a platform product mindset — treating developers as customers. Optionally, we stay on retainer to evolve the platform as your company grows from 30 to 100 to 500 engineers.
Who We Help with Platform Engineering in London
Growing Startups (20-50 Engineers)
You have outgrown ad-hoc infrastructure management. Developers wait for environments, deployments are inconsistent, and your 2 DevOps people are the bottleneck for every release.
Typical project: £32K-£48K, 6-8 weeks
Scale-ups (50-200 Engineers)
You have Kubernetes, CI/CD, and cloud infrastructure — but every team does things differently. You need standardisation, golden paths, and a self-service platform that enforces best practices.
Typical project: £48K-£80K or monthly retainer
Enterprises (200+ Engineers)
Multiple teams, multiple tech stacks, regulatory requirements. You need an enterprise-grade IDP with compliance guardrails, multi-tenancy, and integration with your existing ITSM and security tooling.
Typical project: Assessment + phased engagement
Common Questions About Platform Engineering in London
How much does platform engineering consulting cost in London?
Platform engineering consulting in London ranges from £32,000 to £80,000 ($40,000-$100,000) for a full Internal Developer Platform build (6-12 weeks), or £12,000-£24,000 per month for ongoing platform team retainer. A 2-week platform assessment starts at £4,000-£8,000. This is typically 40-60% less than hiring a 3-person platform team at London salaries.
When does a London company need platform engineering?
When you reach 20-30 engineers and developers spend more than 20% of their time on infrastructure instead of features. Common triggers: developers waiting days for environments, inconsistent deployments across teams, compliance slowing releases, and infrastructure knowledge trapped in 2-3 people’s heads.
What is an Internal Developer Platform and why do London companies need one?
An IDP is a self-service layer that abstracts infrastructure complexity so developers can deploy and manage applications without deep Kubernetes or cloud expertise. For London companies, it embeds FCA and UK GDPR compliance into golden paths, enforces security standards automatically, and reduces the bottleneck on infrastructure specialists.
Do you use Backstage for platform engineering?
Backstage is one of our primary tools — we deploy and customise it with software catalogue, TechDocs, scaffolder templates, and custom plugins. However, for smaller teams under 30 engineers, we sometimes recommend lighter approaches like custom CLI tools or Port.io. We assess your needs first and recommend the right tool.
How long does it take to build an Internal Developer Platform?
MVP in 6-8 weeks: self-service provisioning, standardised CI/CD, service catalogue, and golden paths. A full-featured IDP with Backstage and comprehensive templates takes 10-16 weeks. We recommend starting with the MVP and iterating based on real developer feedback.
