Comprehensive Infrastructure as a Service (IaaS) Solutions

Our Infrastructure as a Service (IaaS) offering is not an off-the-shelf solution. We tailor infrastructure solutions to meet the specific needs of your particular business, whether that means working with your existing equipment, providing on-site support, or calling on trusted partners for specialist requirements.

If your business has particular security concerns, compliance pressures, or operational constraints, we'll work with you to build a setup that truly fits your needs.

Hardware

We supply, configure and help manage all the physical components your business needs:

Our team is highly experienced in ensuring everything is optimised for performance and reliability, with proactive monitoring and support tailored directly to your business.


Software

From operating systems to your bespoke line-of-business applications, we manage:

  • OS deployment and updates
  • Application licensing and patching
  • Provision of your line of business (LOB) apps

We also integrate security into every layer - from endpoint protection to secure configurations - ensuring your IT environment is safe and compliant.


Networking

We design and maintain robust network infrastructures:

  • Routers, switches and firewalls configured for speed and security
  • VPNs and remote access for hybrid or multi-location teams
  • Network monitoring and optimisation to prevent downtime

Security is baked into every networking solution, with firewalls and access controls tailored to your business needs.


Cloud Services

We help SMBs embrace the cloud with scalable, secure solutions:

  • Azure Virtual Desktop for remote and hybrid work
  • Cloud-hosted servers for flexibility and cost-efficiency
  • Backup and disaster recovery to protect your data

Whether you're migrating to the cloud or want to improve your current setup, we make it seamless and secure.

We have used The Final Step as our IT support for nearly a year and a half and we couldn’t be happier with the level of service that they provide. They have helped to massively transform our IT infrastructure, enabling us to tighten our security as well as seamlessly moving us to cloud-based working.

Why you should choose us over other infrastructure management companies

Is your infrastructure ready for hybrid work, secure collaboration and investor scrutiny?

Our services help you organise workloads for better sharing, security and recovery - whether you're using cloud, traditional on-premises setup or a hybrid setup. We work with businesses that need reliability, speed and control, and we help them build IT environments that support growth and meet rising expectations from regulators, insurers and stakeholders.


Scalability and Flexibility

Our IT IaaS for London's small and medium-sized businesses and enterprises offers unparalleled scalability to accommodate business growth without infrastructure constraints.

Scale server capacity up or down based on demand, add cloud storage as needed and expand networking capabilities seamlessly. This flexibility enables rapid response to market opportunities whilst controlling infrastructure costs through optimised resource allocation.


Return on Investment and Operational Efficiency

Our managed IT infrastructure services are built to deliver long-term value. Whilst moving to platforms like Microsoft may initially increase costs compared to legacy providers, the long-term benefits are clear - improved reliability, better security and infrastructure that supports how your business actually works. We help you invest in systems that scale with your needs, meet compliance demands and reduce the risk of downtime or data loss.

Our infrastructure lifecycle management ensures optimal performance throughout your technology investment, whilst our IT backup solutions protect against data loss and operational disruption. Transform fixed infrastructure costs into flexible operational expenses aligned with business performance.

IT Infrastructure Management FAQs

What specific service tiers and pay-as-you-go structures do you offer and how do you calculate monthly charges?

We no longer offer a pay-as-you-go model. Our service is structured around three tiers: Essentials, Enhanced and Evolved, each adding increasing layers of security protection.

  • Essentials: unlimited helpdesk support, proactive maintenance and strategic IT planning. The foundation of our service and the minimum requirement for working with us.
  • Enhanced: everything in Essentials, plus Advanced Email Protection, Microsoft 365 data backup and encryption.
  • Evolved: everything in Enhanced, plus MDR (Managed Detection and Response), SIEM (Security Information and Event Management), Vulnerability Management, Security Awareness Training and a Password Manager.

Individual services can also be added outside of these tiers. Your monthly charge is based on the number of users requiring support, plus any applicable licensing or software costs. Whichever tier you choose, the service and responsiveness you receive from our team remains identical. We apply the same standards to every client and every user.

As a London-based provider, how does your local presence guarantee better performance and superior support for London SMBs and enterprises?

Being close to our clients matters in practical, tangible ways. If you need an engineer on-site at short notice, we can usually make that happen. If you are receiving a hardware delivery and need us to take it on your behalf, we can do that too. On-site support costs less when travel distances are short, meaning you are not paying a premium every time an engineer needs to come in.

Beyond logistics, proximity contributes to a better working relationship. Face-to-face meetings, site visits and being genuinely accessible to your team all make a difference. It is the kind of thing that is easy to underestimate until you have experienced the alternative.
How do your specific IaaS security and compliance measures meet UK/GDPR requirements and what guarantees are in your SLA?

We design our cloud infrastructure to protect personal data and keep services running, in line with UK legislation and GDPR requirements. In practical terms, that means:

  • Only the right people have access to systems and data, and we use extra checks (like MFA) for all users.
  • Systems are shielded from the public internet unless there’s a clear business reason.
  • Updates and fixes are applied regularly to close security gaps.
  • Data is protected and backed up, with the ability to restore quickly if something goes wrong.
  • Activity is monitored so we can spot and respond to issues fast.
  • We can also help with on-site requirements (e.g. comms cabinets and cabling) so the whole setup is secure end-to-end.
  • Uptime targets so your services are available.
  • Clear response times and escalation for urgent issues.
  • Recovery objectives so you know how quickly data and services can be restored.
  • UK/EU data location options and timely incident notifications if something serious happens.
  • Regular reviews and reporting so you have evidence for stakeholders and auditors.

What we commit to in the SLA (at a glance):

  • Uptime targets so your services are available.
  • Clear response times and escalation for urgent issues.
  • Recovery objectives so you know how quickly data and services can be restored.
  • UK/EU data location options and timely incident notifications if something serious happens.
  • Regular reviews and reporting so you have evidence for stakeholders and auditors.

Ultimately, we keep access tight, exposure low, systems updated, data protected and we back this with clear, business-friendly commitments in the SLA.

What is your proven step-by-step process for migrating our existing on-premise infrastructure to your cloud solution?

We follow a structured, low-risk approach designed to minimise disruption and keep the business in control throughout.

  1. Assess and plan – We review your current infrastructure, understand what the business needs, and agree what should move, what shouldn’t and why.
  2. Design the target solution – We design a cloud setup that meets your performance, security and compliance requirements.
  3. Prepare and test – We ready systems, users and data, and test the migration approach before anything critical moves.
  4. Migrate in stages – Systems are migrated in a controlled order to reduce risk and downtime.
  5. Validate and optimise – We confirm everything is working as expected and fine-tune performance and costs.
  6. Handover and support – We document the new environment and provide ongoing support or management if required.

The focus is always on business continuity, clear communication and no surprises.

What criteria should an SMB use to evaluate your IaaS solution versus a global provider?

Choosing the right infrastructure provider is about more than price. Here are the criteria worth weighing up:

  • Support model: do you get direct access to experienced engineers when something goes wrong, or are you navigating a self-service portal with paid support tiers?
  • Fit for purpose: is the infrastructure designed around your workloads, or a vast hyperscale platform you have to adapt to?
  • Cost predictability: are your costs easy to forecast and control, or variable and easy to underestimate?
  • Security and data residency: where is your data hosted, and are the compliance responsibilities clearly defined?
  • Flexibility: can the service scale and adapt quickly as your business evolves?
  • Integration: does the infrastructure align seamlessly with your managed IT, security and continuity services?
  • Partnership approach: are you treated as a long-term client with proactive guidance, or one of thousands of anonymous accounts?

For most SMBs, a specialist provider delivers better simplicity, clearer accountability and more business-aligned support than a global self-service platform.

Can you detail the full technical scope of your offering, including hardware, data centre locations and virtual machine capabilities?

Our IaaS offering provides a secure, UK‑hosted cloud platform designed to support day‑to‑day business systems as well as more critical workloads.

At a high level, it includes:

  • Enterprise‑grade hardware, designed for resilience and performance, with built‑in redundancy
  • UK data centre locations, supporting data residency and regulatory requirements
  • Virtual servers (VMs) that can be sized and adjusted to match your needs, including CPU, memory and storage
  • Secure networking, allowing systems to be accessed safely from offices, remote users or other cloud services
  • Backup and disaster recovery options, to protect data and support business continuity
  • Ongoing maintenance, including patching and platform updates, so the environment stays secure and reliable

The service is flexible by design, allowing capacity and capabilities to scale as your business changes, without the need to invest in or manage physical infrastructure yourself.
