Cloud & infrastructure services for UK organisations
Cloud migration, hybrid infrastructure and datacentre services that modernise your IT without disrupting the business that runs on it.
Cloud migration, planned and delivered end-to-end
Moving to the cloud is one of the highest-stakes changes you can make to your IT, and one of the easiest to get wrong. Our cloud migration services take that risk off your plate. We assess what you have, plan the move workload by workload, and migrate you to AWS, Azure or Google Cloud without the downtime, cost overruns or security gaps that derail rushed migrations.
Every migration starts with discovery: understanding your environment, your dependencies, and the right order to move things in. From there we run the whole programme, from first assessment to full handover, and stay with you afterwards to keep the environment secure, optimised and cost-efficient. Whether you're moving a single workload or consolidating multiple sites, you get a clear plan, one point of accountability, and a migration your users barely notice.
The infrastructure problems we typically fix
On-premise infrastructure is expensive and inflexible
Capital costs, maintenance and refresh cycles tie up budget that could be working elsewhere.
Cloud migrations can go wrong
Without proper planning, you risk downtime, cost overruns and security gaps that take months to unpick.
Most businesses overspend on cloud capacity
Overprovisioned environments waste money; underprovisioned ones slow the business. Few optimise either side actively.
Hybrid environments are complex to run
Co-ordinating on-premise, cloud and colocation needs expertise most mid-market IT teams cannot keep in-house.
Cloud & infrastructure services
Six services that cover the full lifecycle, from first assessment to ongoing optimisation.
Cloud assessment & migration
A roadmap and full execution scoped to your environment and dependencies. We map what you have, decide what should move, then migrate in a sequence that keeps the business running.
Infrastructure-as-a-Service (IaaS)
Managed cloud infrastructure tailored to your workloads, so you get the capacity you need without buying and maintaining hardware. Sized right from the start.
Cloud cost optimisation
Cloud bills grow quietly. We identify waste, right-size what's running and bring monthly spend under control, typically finding savings of 20 to 40 percent.
Datacentre migrations
End-to-end relocation planned around your business. We manage the whole cutover, with a tested rollback path in place, so operations keep moving.
Infrastructure health checks
A clear assessment of performance, security and capacity, so you can plan ahead with confidence. A prioritised picture of what needs attention now.
Installation services
Servers, storage and networking deployed to your specification by engineers who install this kit every week. Sourced through our own hardware supply service.

Sectors we work with
Cloud & infrastructure for every sector. Three of the industries where infrastructure modernisation matters most:
Manufacturing
Integrate IT and OT environments and build the infrastructure resilience that keeps production lines running when something goes wrong.
Retail & wholesale
Scalable cloud infrastructure that handles seasonal peaks without over-provisioning year-round, with reliable access for distributed teams.
Charity & not-for-profit
Cost-efficient cloud environments that reduce IT overhead, improve reliability and free up resource for the work that matters most.
Certified to standards you can check
Highgate’s managed services run under an ISO 9001 certified quality management system, so you get dependable, repeatable delivery backed by documented processes and a 24/7 UK-based service desk.
Cloud & infrastructure insights
Cloud & infrastructure: frequently asked questions
Should we move everything to the cloud?
For most businesses, no. The right answer depends on your workloads, your regulatory environment and your existing infrastructure investment. Cloud is the better option for many applications – flexible, scalable, no hardware refresh cycle – but some workloads run better on-premise, some have data residency or compliance requirements that complicate cloud adoption, and a wholesale migration is rarely the most cost-effective path. We assess your environment workload by workload and give you a clear recommendation, which for most businesses is a hybrid model that moves what makes sense and keeps what does not. The goal is the right infrastructure for your business, not cloud for its own sake.
How long does a cloud migration take?
It varies significantly with the complexity of your environment, the number of workloads being moved, and how much preparation is needed upfront. A straightforward migration for a smaller business might take six to eight weeks. A more complex programme across multiple sites, legacy systems or significant data volumes is typically measured in months. The businesses that experience the smoothest migrations are the ones that invest in discovery and planning – understanding what they have, the dependencies, and the right sequence – before anything moves. Rushing the plan to accelerate the timeline is the single most common cause of migrations that overrun.
What's the ROI of cloud vs on-premise?
More nuanced than it first appears. Cloud removes capital expenditure on hardware and refresh cycles, but operational costs (licensing, storage, egress fees) can grow quickly without governance. On-premise carries higher upfront costs but can be more predictable over a longer horizon for stable workloads. The businesses that see the strongest ROI from cloud are typically the ones that actively manage their cloud spend rather than lifting and shifting existing infrastructure. We help clients model the true cost of both options before committing, and for those already in the cloud our cost optimisation work typically identifies savings of between 20 and 40 percent on existing cloud bills.
How do you ensure zero downtime during migrations?
Careful planning, staged execution, and a refusal to cut over until the new environment is stable. In practice that means running parallel environments during the transition, migrating workloads in a sequence that respects dependencies, and scheduling any required cutovers during low-traffic windows. We test thoroughly before each migration step and keep a rollback path live throughout, so if something unexpected occurs we can revert quickly. The goal is that your users notice the performance improvement after a migration, not the migration itself.
What happens after our cloud migration is complete?
Migration is the starting point, not the finish line. Keeping a cloud environment secure, optimised and cost-efficient takes ongoing attention. Our proactive managed services mean you are not left to run it alone – we monitor, maintain and continuously improve your cloud setup as your business evolves.
Do you handle IT migrations other than cloud?
Yes, and they are a good share of the work. Cloud is one destination among several. The same assessment and sequencing process covers tenant-to-tenant Microsoft 365 consolidations after a merger or acquisition, data centre and office moves, on-premises server refreshes, and moves between cloud platforms where the original choice stopped fitting. What does not change is the order the work happens in: map the dependencies, model the cost, sequence by risk, and hold a rollback position at every stage. If you are moving something and are not sure which category it falls into, that is what the assessment is for.
