Progressive Web Apps (PWA) Company in the UK

Techglock delivers Progressive Web Apps (PWA) for UK-based businesses — from London fintech scale-ups to Manchester-based SaaS startups and Edinburgh enterprise IT. Our engagements are GDPR-native by default: data residency in EU/UK regions, ICO-aligned DPIA documentation, and PECR-compliant marketing surfaces. Contracts are UK-style: clear IP assignment, indemnity for sub-processors, and GBP invoicing through our preferred UK bank rails. We work with clients across London, Manchester, Edinburgh, Bristol, Cambridge, Birmingham, and Leeds.

Service Overview

Progressive Web Apps represent the convergence of web reach and native app capability. PWAs are installed directly from the browser, work offline via service workers, deliver push notifications, and load in under a second on repeat visits — all without the publishing overhead of native app stores. For businesses targeting mobile-first audiences, PWAs routinely deliver 3–5× improvements in mobile conversion rates over traditional web experiences.

Performance as a Feature: Techglock builds PWAs to Lighthouse performance standards — targeting 90+ scores across Performance, Accessibility, Best Practices, and SEO. We implement app shell architecture, aggressive caching strategies, lazy loading, and code splitting to ensure sub-second first contentful paint even on 3G connections. Every interaction feels instant, every page transition is smooth, and offline mode degrades gracefully.

Business Impact: PWAs are particularly powerful for e-commerce, media, and SaaS companies who want to bridge the gap between web acquisition and app engagement. Our clients routinely see 30–50% improvements in session duration, 20–40% reductions in bounce rate, and significant gains in mobile checkout completion rates after migrating to PWA architecture.

Frequently Asked Questions

The questions clients ask most often before kicking off a progressive web apps (pwa) engagement.

How long does a progressive web apps (pwa) engagement take?
Most progressive web apps (pwa) projects ship within 8–14 weeks. Typical timeline: 1 week for discovery and scoping, 1–2 weeks for solution design, 4–8 weeks of agile delivery sprints, and 1–2 weeks for QA, security review, and go-live. We give you a fixed timeline before any work starts — no surprises three months in.
How much does progressive web apps (pwa) cost with Techglock?
Pricing depends on scope, but most progressive web apps (pwa) engagements land between $15,000 and $80,000 depending on complexity, integrations, and team size. We offer both fixed-price and time-and-materials models. Every quote breaks down per-deliverable so you can scale up or scale back before committing.
Do you sign NDAs before discussing the project?
Yes — request a mutual NDA when you book the discovery call and we send it within the hour. We have signed thousands of NDAs across regulated industries (healthcare, finance, defence) and never had a confidentiality dispute.
What does your progressive web apps (pwa) team look like?
Every engagement gets a dedicated squad: a senior tech lead, 2–4 engineers, a project manager, and (where relevant) a designer or DevOps engineer. No offshore handoffs, no junior-only teams, no rotating staff. The people you meet on day one are the people who ship the project.
What happens after the Progressive Web Apps (PWA) project launches?
Every engagement includes 30 days of free hypercare (bug fixes, performance tuning, user-feedback iteration). Beyond that, we offer monthly retainers from $1,500/month covering monitoring, security patches, dependency updates, and a fixed pool of iteration hours. Roughly 80% of clients move onto a retainer after launch.
Who owns the code and IP we build together?
You do — completely. Once final invoice is settled, all source code, designs, infrastructure-as-code, and CI/CD pipelines transfer to your accounts. No vendor lock-in, no licensing fees on code we wrote, no hidden escrow.
