Pre-Market Engagement (PME) – Data and Insights Transformation Partner

This Pre-Market Engagement (PME) Notice issued by Tai Tarian to encourage Data and Insights Transformation Partner suppliers to register and attend a meet the buyer session for an anticipated procurement process.

Tai Tarian is a not-for-profit Registered Social Landlord (RSL) responsible for managing and maintaining more than 9,000 homes across Neath Port Talbot.

Since our establishment in 2011, we have focused on delivering safe, efficient, and sustainable homes that support thriving communities.

We are now delivering a multi-year transformation programme aimed at improving customer experience, colleague engagement, organisational efficiency, and our ability to make data-driven decisions.

Tai Tarian’s transformation is structured around five inter-linking workstreams:

1. Customer Experience – Improving services and interactions for tenants and communities.
2. Colleague Experience – Enabling a skilled and motivated workforce through better tools and insight.
3. Organisational Excellence – Clarifying processes and strengthening governance and accountability.
4. Data and Insights – Creating integrated, trusted data foundations that support evidence-based decisions.
5. Business Systems – Modernising and connecting systems to improve accuracy, efficiency, and service quality.

This Pre-Market Engagement (PME) aims to understand the capability and capacity within the market to deliver an integrated Data and Insights Transformation Partnership.

Information gathered will inform the final scope and design of a formal procurement to be advertised on Sell2Wales in early 2026.

The programme will replace core business systems in two stages:

• Starting H1 2026: HR, Payroll, and Finance systems.
• Starting H2 2026: Housing Management, Asset Management, Customer Portal, and Field Service (including works scheduling).

To support these changes, Tai Tarian plans to implement a phased Data and Insights Transformation that establishes a single, governed data platform. The supplier will help transition from legacy structures to Housing standard data models, first within the analytics layer of existing systems, then through data migration and integration into the new systems as they go live.

This approach ensures continuity of reporting, insight, and compliance throughout the system replacements and creates a sustainable, standardised data foundation for the future.

The Data and Insights Transformation Partner will support delivery across the five phases of Tai Tarian’s Data and Insights Transformation Programme, forming a core part of our wider organisational change agenda.

Phase 1 – Build Data Platform

Design and implement a secure and scalable data platform to provide a single source of truth across key business domains. This phase will establish foundational datasets, governance, and data models to enable future phases.

Key functions may include:

• Consolidation of data into a single, governed environment.
• Definition of core data entities (tenant, asset, property, finance, HR).
• Implementation of structured data storage, lineage tracking, and metadata standards.
• Establishment of data ownership, stewardship, and quality controls.

Phase 2 – Migrations and Integrations

Develop the ETL and integration capability required to move and align data between legacy and modern systems. This will ensure consistent, timely, and accurate information across organisational platforms.

Key functions may include:

• Data migration planning, transformation, and validation activities.
• Development of automated Extract, Transform and Load (ETL) processes.
• Implementation of master data management and cross-system interoperability.
• Testing and assurance to confirm data accuracy and completeness post-migration.

Phase 3 – AI-Powered Data Cleansing

Introduce automation and rule-based validation to improve data quality, consistency, and usability across the organisation. This will underpin a shift towards self-service reporting, insight generation, and predictive analytics.

Key functions may include:

• Deployment of automated data-cleansing routines and dashboards.
• Application of business rules to identify and resolve duplicates or anomalies.
• Establishment of feedback loops for continuous data improvement.
• Support for data literacy and culture development across teams.

Phase 4 – Analytics Layer Buildout

Develop an integrated analytics and insight capability to deliver actionable information to decision-makers, colleagues, and stakeholders. This will enable evidence-based planning, regulatory reporting, and performance management.

Key functions may include:

• Creation of standardised reporting datasets and dashboards.
• Development of analytics models supporting operational, financial, and sustainability outcomes.
• Implementation of self-service tools for managers and teams.
• Support for environmental and ESG reporting, including decarbonisation progress.

Phase 5 – AI Services & Co-Pilot Development

Establish an insight-driven culture by embedding intelligent automation, predictive modelling, and data-driven decision-making into services. This phase will focus on long-term enablement and innovation.

Key functions may include:

• Development of early AI-enabled use cases that enhance efficiency and tenant experience.
• Introduction of natural-language and conversational query tools for insight access.
• Design of governance processes for ethical and responsible automation.
• Continued capability-building for Tai Tarian’s internal Data & Analytics function.

Each phase will be delivered in alignment with Tai Tarian’s Data Strategy, Information Management Framework, Sustainable Planet Strategy, and Target Operating Model, ensuring that all solutions support long-term sustainability, compliance, and operational excellence.

Meet the Buyer Sessions

Interested suppliers may invited to attend ‘Meet the Buyer’ sessions, held on Monday 1st December and Tuesday 2nd December 2025 at Tai Tarian’s offices.

To register your interest in attending please email [email protected]. Please note that you must email [email protected] to register your interest in attending, no other method of registering will be accepted.

The deadline to register is 12PM Friday 21st November 2025.

The session will allow interested suppliers the opportunity to meet with Tai Tarian’s representatives to gain an understanding of our requirements.

For example, we are asking interested suppliers:

• How their proposal could bring benefit to Tai Tarian and our stakeholders.
• What makes a contract attractive to them.
• Their experience of undertaking similar contracts.
• Their experience both within and outside the Housing sector.
• Lessons learnt from previous contracts.
• Why they want to work with Tai Tarian.
• Innovative ways of working (doing things differently)

Please note that ‘Meet the Buyer’ sessions will only be carried out on specified days and that slots will be reserved by Suppliers on a first come first served basis. When all slots are filled, we will be unable to extend these sessions further. However, depending on the level of market interest, Tai Tarian reserves the right to reduce the number of interested Suppliers by using a questionnaire or another mechanism before opening slots, to ensure the best use of Tai Tarian resources by meeting relevant Suppliers over the specified period for the Meet the Buyer sessions. If this mechanism is used, then Tai Tarian will ensure equal treatment of all interested Suppliers and will share any relevant findings and information (when not commercially sensitive) from the Meet the Buyer sessions to all interested Suppliers.

Please note that recording an interest is voluntary and potential tenderers will not be advantaged or disadvantaged through participation in any ‘Meet the Buyer’ session and any discussions held will not form part of any formal tender process. Tai Tarian reserves the right to change its requirements prior to the Tender Notice being issued and this PME does not commit Tai Tarian to undertake any procurement process.

It is anticipated that a Tender Notice will be published in the coming months.

The estimated contract value and estimated contract period provided in this Notice are for indicative purposes only and the estimated contract value and estimated contract period will be confirmed in any future Tender Notice.
