Building stronger quality foundations for reliable energy services
Challenge
A leading UK energy company needed to modernise quality engineering, increase automation maturity and improve consistency across digital delivery.
Approach
Resillion modernised web, API and mobile automation using Playwright, WebDriverIO and Appium, with early exploration of AI-assisted testing to support more efficient automation creation
Results
The organisation is building a more scalable automation capability, helping teams release change with greater confidence and deliver more reliable digital services for customers.
Supporting smarter, safer digital transformation in energy
The client is one of the UK’s leading integrated energy companies, supplying electricity and gas to millions of homes and businesses while investing heavily in the technologies that will support a smarter, more sustainable energy future.
As digital transformation accelerates across the energy sector, software quality has become increasingly important to delivering reliable digital services, supporting operational resilience and enabling innovation. For customers, that can mean smoother app journeys, fewer service issues and greater confidence when managing accounts, payments or new energy products. The client wanted to modernise its quality engineering capability, increase automation maturity and create a more consistent approach to assuring change across its digital platforms.
Resillion is helping the organisation achieve this through a modern quality engineering strategy that combines scalable automation, shared standards and independent assurance, enabling teams to deliver change with greater speed and confidence.
The challenge: Building quality for the next generation of digital services
The client’s digital landscape spans multiple business units, technologies and delivery teams. These systems support important customer and operational journeys, from account management and payments to field activity and new energy services. Maintaining consistent quality across this environment while supporting faster software delivery presented a growing challenge.
Traditional manual testing remained valuable, but it could no longer provide the scale or consistency required for an increasingly agile delivery model. Automation existed across the organisation, but approaches varied between teams, making frameworks harder to maintain and limiting opportunities for reuse.
At the same time, the client wanted to make automation easier to scale across delivery teams.
The client needed a quality engineering partner that could help modernise automation, increase reuse and build more scalable ways of assuring software quality across a complex delivery environment.
Our approach: Modern quality engineering with scalable automation
Resillion is supporting the client through a quality engineering programme designed to modernise automation and make testing more scalable, maintainable and accessible across delivery teams.
Resillion is helping the client transition from legacy automation technologies towards a modern TypeScript-based framework covering web, API and mobile testing.
Rather than simply migrating existing scripts, the programme focuses on creating maintainable automation that delivers long-term value. Existing frameworks are being rationalised, duplicated tests removed and automation aligned around the customer journeys and business processes that matter most, so teams can test the real experience customers depend on, not just the underlying code.
By adopting technologies including Playwright, WebDriverIO and Appium, the client is building a more scalable automation capability that can evolve alongside its digital platforms.
Resillion is also helping the client make automation more accessible across delivery teams, so quality engineering can scale beyond specialist automation resources.
Where appropriate, AI-assisted scripting can help testers describe scenarios using plain language before generating framework-aligned automation. This supports more efficient test creation while keeping experienced testers focused on risk, business context and quality decisions
Results: Creating stronger foundations for digital transformation
By modernising automation and strengthening delivery standards, the client is building stronger quality foundations to support ongoing digital transformation. This helps teams find issues earlier, reduce late-stage surprises and release updates with greater confidence.
For customers, the impact is simple: digital services are more likely to work smoothly when they need them, whether they are checking account information, managing payments or using new smart energy features.
Key outcomes include:
Modern automation frameworks that improve maintainability across web, API and mobile testing
Greater release confidence through more consistent quality gates, automation and evidence-based decision making, helping teams launch changes with fewer late-stage issues
More reliable digital journeys for customers across account, payment and new energy services
Broader participation in automation by enabling manual testers to contribute using AI-assisted scripting
A more scalable approach to software assurance across complex digital platforms
Improved collaboration between quality engineering and delivery teams through shared standards and clearer automation priorities
A scalable quality engineering capability that supports innovation while maintaining control across a complex regulated environment
Modern quality engineering is about building confidence into delivery. By creating scalable automation, shared standards and stronger quality gates, organisations can release change faster while protecting the digital services customers rely on every day.
The Total Quality perspective
For organisations delivering essential energy services, quality engineering is no longer simply about finding software defects. It is about making sure digital services work as expected for the people and teams who rely on them, while enabling innovation, operational resilience and regulatory confidence.
By combining modern automation, shared standards and independent assurance, Resillion is helping the client build a quality engineering capability that can support both today’s digital platforms and future innovation.
As the energy sector continues to evolve, the client is developing the foundations to deliver change faster without compromising the quality, safety and reliability that customers depend on every day.
