Leith(Edinburgh Daily) July 01, 2026 – One Mortgage System (OMS) has confirmed that it has secured CRM contract renewals with two UK intermediaries, Promise Money and Leith Mortgage Centre, marking further momentum in its client retention strategy for 2026.

As reported by The Intermediary, OMS stated that the renewed agreements will see both Promise Money and Leith Mortgage Centre continue using the OMS platform to improve efficiency levels. The announcement follows a similar renewal earlier in the year, when OMS confirmed the extension of its technology agreement with Complete FS, another specialist distributor.

The Intermediary noted that the renewals underline OMS’s ongoing focus on maintaining long-term relationships with intermediaries that rely on its CRM and loan origination capabilities. OMS describes itself as a CRM and loan origination platform for intermediaries and lenders, indicating that its technology is designed to support both advice and product-selection workflows across the mortgage lifecycle.

While the announcement does not disclose the length of the renewed contracts or specific commercial terms, the decision by both Promise Money and Leith Mortgage Centre to stay with OMS suggests that the platform continues to meet their operational and strategic needs. In an industry where brokers frequently evaluate CRM options as part of wider technology refreshes, such renewals are often seen as a measure of product stability and customer satisfaction.

Why Do These Renewals Matter for the UK Mortgage Intermediary Sector?

The OMS renewals with Promise Money and Leith Mortgage Centre are significant for the UK mortgage intermediary market because they highlight the retention of established clients in a competitive CRM environment. Brokerages and mortgage centres increasingly treat CRM technology as a core component of their service delivery, dependency on a single platform often growing as firms embed it into case management, compliance, and reporting processes.

As reported by The Intermediary, the renewed agreements will see both firms continue using the OMS platform to improve efficiency levels, suggesting that OMS is being credited with tangible operational benefits. Efficiency improvements in this context typically include faster case progression, reduced manual data entry, better integration with lenders and portals, and more streamlined compliance workflows – all of which can affect a firm’s cost base and service quality.

Mortgage Strategy and similar industry outlets have frequently covered OMS contract news as an indicator of platform momentum, with renewals often framed as validation of the system’s fit for purpose among intermediaries. The fact that OMS has now announced multiple renewals in 2026 – including with Complete FS earlier in the year – reinforces a narrative that the platform is maintaining its position among specialist and high-volume intermediaries.

From a market perspective, these renewals also suggest that intermediaries are not necessarily switching away from incumbent CRM providers in search of newer alternatives, but are instead opting to deepen existing relationships when platforms deliver measurable efficiency gains. This tendency can slow churn in the CRM space and create a more stable competitive landscape, where established players like OMS can leverage long-term client relationships to drive further growth.

How Do These Renewals Fit Into OMS’s Overall Technology Strategy?

The OMS renewals with Promise Money and Leith Mortgage Centre align with the company’s stated strategy of supporting intermediaries and lenders through an integrated CRM and loan origination platform. As reported by The Intermediary, the renewed agreements will see both firms continue using the OMS platform to improve efficiency levels, indicating that OMS is positioning its technology as a driver of operational performance rather than merely a data repository.

Earlier in 2026, OMS confirmed the renewal of its technology agreement with Complete FS, a specialist distributor, demonstrating a pattern of long-term contract extensions with key partners. This pattern suggests that OMS is prioritising relationship continuity and ongoing platform investment, rather than pursuing aggressive replacement of existing clients with new ones.

Industry coverage of OMS technology renewals often highlights the importance of CRM systems in managing high volumes of mortgage applications, maintaining compliance records, and supporting lender panel management. By securing renewals with firms such as Promise Money and Leith Mortgage Centre, OMS reinforces its position as a preferred platform for intermediaries that require a robust, scalable system capable of supporting complex case management and reporting requirements.

Background of the Development: OMS and the UK Mortgage CRM Market

One Mortgage System (OMS) operates as a specialist CRM and loan origination platform designed for the UK mortgage intermediaries and lenders market. The platform is built to support the end-to-end mortgage process, from initial client engagement and financial assessment through to application submission, lender communication, and post-completion administration.

Over recent years, OMS has been frequently cited in industry media such as Mortgage Strategy, The Intermediary, and Modern Lender in connection with new client wins and contract renewals, reflecting its role as one of several established CRM providers in the UK intermediary space. The company’s focus on efficiency improvements aligns with broader market trends where brokers and mortgage centres seek technology that can reduce administrative burden, support compliance, and enable faster case progression.

The renewals with Promise Money and Leith Mortgage Centre are part of a series of 2026 announcements that include the Complete FS renewal, demonstrating OMS’s ongoing emphasis on maintaining and strengthening relationships with existing intermediaries. Such renewals are often interpreted by industry analysts as evidence of platform stability, customer satisfaction, and the maturity of the vendor–client relationship.

Prediction: How This Development Can Affect Mortgage Intermediaries and Their Clients

For Mortgage Intermediaries

The OMS renewals with Promise Money and Leith Mortgage Centre suggest that established intermediaries may continue to prioritise efficiency-focused CRM platforms over switching to new providers, unless there is a clear and substantial improvement elsewhere. This trend could lead to:

• Greater concentration on incumbent CRM providers that have already demonstrated long-term value, reducing churn in the sector.
• More investment by platforms like OMS in efficiency-enhancing features, such as automation, lender integrations, and compliance tools, to retain clients.
• Increased pressure on smaller or newer CRM vendors to offer differentiated value, such as lower cost, niche functionality, or superior user experience, to persuade intermediaries to switch.

For intermediaries considering CRM changes, the OMS renewals may act as a signal that stability and proven efficiency gains can be as important as innovation, particularly for firms that have already integrated OMS deeply into their workflows.

For Brokerage Clients and Mortgage Applicants

The continued use of OMS by Promise Money and Leith Mortgage Centre, with the aim of improving efficiency, could indirectly benefit their clients through:

• Faster case turnaround, as streamlined processes and better integrations reduce delays in application submission and lender communication.
• More consistent service quality, as automated workflows and standardised compliance checks reduce the risk of errors or missed steps.
• Potentially lower operational costs for the intermediary, which could, in some cases, translate into more competitive pricing or value-added services for clients.

However, the impact on individual clients will depend on how each firm implements efficiency improvements and whether they communicate process changes clearly to customers.

For the Wider Market

The OMS contract renewals with Promise Money and Leith Mortgage Centre reinforce a market environment where long-term CRM relationships are valued, particularly when platforms deliver measurable operational benefits. This could:

• Encourage other intermediaries to review their current CRM arrangements with a focus on efficiency and integration, rather than switching purely for novelty.
• Push CRM vendors to emphasise efficiency metrics and case-level performance in their marketing, as intermediaries become more data-driven in their technology decisions.
• Support a more stable competitive landscape, where established players like OMS maintain their position through continued investment and client retention rather than aggressive displacement strategies.

Overall, the OMS contract renewals with Promise Money and Leith Mortgage Centre point towards a sector where efficiency, integration, and long-term platform relationships are becoming central to how intermediaries evaluate and use CRM technology.
