Itransition Reviews & Testimonials
Software Development Review from Robert Hager
Itransition carried out the entire software testing process without a single delay. Despite the remote cooperation, the company ensured ceaseless communication, which indicates a high level of the team’s professionalism and organization.
Software Development Review from Jimmy Carlisle
We needed an in-depth upgrade of the legacy auditing system. We chose Itransition because they swiftly responded to our project requirements and had relevant expertise. The team helped us decide on the solution’s tech stack and designed the new architecture, migrated legacy data, developed new features, and customized the software with extensions. We got a powerful and user-friendly auditing system and were very impressed with the Itransition’s dedication and attention to detail.
Software Development Review from Shoshana Parker
We enjoyed working with Itransition. We needed a solution for transferring health records from our EHR into the data warehouse without losses. We chose Itransition for their experience, portfolio, and past clients’ references, and the team fully met our expectations. They built a custom ETL tool that increased our visibility into clinical data and helped us spot inefficiencies in patient workflows. Needless to say, they also delivered it on time and budget.

Frequently Asked Questions
What are the core specializations of IT services companies in the United Kingdom?
IT services companies in the United Kingdom offer a full suite of digital transformation and operational support services, focused on accelerating business growth, ensuring regulatory compliance, and strengthening security. In addition to core functions like managed IT, cloud hosting, and help desk support, key specializations include:Â
- IT consultingÂ
- Digital strategyÂ
- Managed security services (MSS)Â
- Cloud servicesÂ
- Network infrastructure and unified communicationsÂ
- Data backup and recoveryÂ
- System modernizationÂ
What certifications should an IT support company have?
For IT support companies, certifications signal adherence to global and local best practices. ISO/IEC 27001 is essential, crucial for complying with the UK's high data protection standards, including GDPR. Staff-level certifications like ITIL Foundation are also important, as well as Cyber Essentials for cybersecurity. Â
For assessing technical proficiency, look for vendor accreditations like Microsoft Gold Partner or high-level certifications like CISSP (Certified Information Systems Security Professional) for senior staff.Â
What information do I need to provide to an IT services company?
To initiate a successful partnership with an IT services company, you must be prepared to share detailed information across three critical tiers. Initially, outline your business context: including key growth objectives, the total count of users and endpoints, budget constraints, and a clear list of current IT challenges or 'pain points.'Â
Secondly, you’ll need to supply technical documentation, i.e., a complete inventory of hardware, existing licensed software and their keys, a network topology map, and details on any critical legacy systems. Lastly, you'll need to provide a statement of all mandatory compliance requirements and the necessary access credentials for core systems, such as firewalls, cloud tenants, and primary servers.Â
What factors affect IT services agency pricing?
Pricing for IT services in the UK is heavily influenced by the scope and inherent complexity of the required support, which determines the necessary staffing and skillset. Factors that directly impact costs include: the size and scale of the organization (number of users and managed devices), the stringency of the Service Level Agreement (SLA) required, especially for 24/7 or mission-critical support, and the technical maturity of the existing IT estate.Â
Additionally, stringent regulatory compliance will increase pricing, as well as the agency's location within the UK (London-based services typically cost more due to higher labor rates).Â
What questions should I ask United Kingdom IT support company before hiring?
Before committing to a United Kingdom IT support company, pose these questions to thoroughly assess its suitability, expertise, and operational alignment with your business:Â
- What are your guaranteed response and resolution times as per your Service Level Agreement (SLA)?Â
- How do you ensure full compliance with GDPR and other UK-specific data protection legislation?Â
- Do you operate a 24/7/365 UK-based service desk or is support outsourced after hours?Â
- What is your defined process for handling a high-priority cyber-security incident or major outage?Â
- Can you provide an example of how you've helped a client leverage cloud technology for a business outcome?Â
- How frequently do you conduct proactive security testing, patching, and hardware life-cycle reviews?Â
