IT Services Review from Keiki Ka
HCLTech played a crucial role in supporting our transition to an independent entity, ensuring it was completed within the planned timelines and without any business disruptions. Their global capabilities, expertise in critical projects, and deep understanding of the automotive business value chain made them the ideal IT partner. I highly recommend HCLTech for their excellent digital transformation services, long-term partnership, transparency, and expertise.

Teodora Atanasoaei's Review Sourced from Google
I went to interview for a Delivery Manager role.Had 3 people interview me, one of which was dressed in sports outfit for the interview - I do not regard this as being professional.Second, the role advertised is not the same with the role itself. In the job description, the responsibilities were all related to Project Management, however when the interview started I was completely blindsided.They asked me to basically do the work of Sales, Product Owner, Design, Architecture and we spoke a little of Delivery as well.Only to be told later that because this is a consultancy, it's expected of you to do everything. The job does NOT pay for X5 roles with those responsibilities, but you are expected to do those tasks regardless.My advice - just write down all of these in the job advert, saves people time to decide whether it is suited for them or not.

Apadmi Reviews & Testimonials
Thomas Booth's Review Sourced from Google
I recently had an experience back in 2022 with Apadmi that I feel compelled to share and have debated whether i should post this. As a professional eagerly looking forward to an interview with Apadmi, I was unfortunately met with a series of disappointments.Firstly, the structured process I was initially promised for the interview was not adhered to. This lack of organisation not only threw me off but also made it challenging to present myself effectively and forced to do a presentation in less than 24 hours notice.More concerning, however, was my interaction with the Managing Director, not sure if he is still there. I found his demeanour not just unprofessional but outright rude. This was disheartening, especially coming from a leadership figure in a reputable company. I've actually never been so humiliated in the professional environment.It's important for companies to remember that interviews are a two-way process. They are not just about evaluating candidates, but also about demonstrating the company's values and culture. Unfortunately, my experience with Apadmi fell short of the professional standards one would expect, however i would say Marcus, one of the board members was a delight in my first stage.I hope my feedback is taken constructively, as it is intended to highlight areas where there is significant room for improvement in how Apadmi manages its recruitment process and senior staff interactions.
Steve Jackson's Review Sourced from Google
Fantastic team, you can rely on them always.. Robert a partner of Apadami is an exceptional individual who supported me with my project in a professional manner. With his excellent peoples skills he will look after you. The person you can rely on anything and keep you assured. Will always go back to Apadami.
Manoj Ranaweera's Review Sourced from Google
Apadmi's ability to spin out technology as separate companies is remarkable. A strong supporter of Manchester tech ecosystem, they became unbeatable in mobile category during the first three years of northern tech awards before it adopted a new structure and ownership. Another remarkable achievement is that the four founders have remained together during all these years. I wish them all the best.

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
