An AWS Partner UK is a British company accredited by Amazon Web Services to design, migrate and run AWS environments. For an SME moving off on-premise hardware, the choice of partner matters more than the choice of migration tooling, because the partner decides the sequence, the guardrails and what happens when a cutover goes sideways.
Most guides to this subject explain how to migrate. That is the easy half. The harder question, and the one buyers actually ask, is who should do it and how you tell a genuine engineering partner from a reseller with a logo. This covers both, starting with the partner.
A reseller can provision your accounts and pass through your AWS bill. A services partner does the architecture, the migration and the running of it. The difference only becomes obvious when something breaks.
What Is an AWS Partner UK?
A UK-based company AWS has formally accredited to sell, build and manage services on its cloud platform. Partners sit in tiers, and the tier signals how much delivery they have proven rather than claimed. It is awarded by AWS on published criteria, which is why an AWS Partner UK badge cannot be self-declared.
An AWS Advanced Tier Partner has cleared a high bar of certified engineers and validated customer migrations. That is the experience an SME wants on a project where downtime has a direct cost, and it is the tier Transputec holds as an AWS Advanced Tier Services Partner.
Tier alone is a filter rather than an answer. It tells you a firm has the certifications and the deployments behind it. It tells you nothing about whether they have done your migration, in your sector, at your size.
Reseller or Services Partner: Which Do You Need?
Two different things get sold under the same word. A reseller provisions accounts and passes through your AWS billing, which is genuinely useful if you already have the engineering in house. A services partner does the work: architecture, migration, security and day-to-day operations.
The test is simple. Ask who writes the landing zone design, who runs the cutover weekend, and who answers at three in the morning when a workload fails over. If the answer to any of those is ‘you do’, you are buying a reseller agreement, whatever the contract calls it.
For an SME with no spare platform engineer, the services route is usually the only one that works. Transputec operates as a services AWS Partner UK, with named architects in the UK and ISO 27001 governance across the engagement.

Get a Strategic ConsultationWhat Does Staying On-Premise Actually Cost?
More than the hardware line in the budget. On-premise kit depreciates whether you use it or not, and every refresh cycle lands as a capital outlay. The costs that hurt most are the ones nobody forecasts: a failed disk array, a flooded comms room, a ransomware hit that takes the business offline for days.
Disaster recovery is the usual weak point. Most SMEs have a documented DR plan and very few have a tested one, and the gap between those two states only becomes visible on the worst possible day. Cloud infrastructure you can rebuild in minutes changes that calculation, which is why disaster recovery as a service tends to be the first thing that gets properly tested after a move.
The UK government’s own Cloud First policy reflects how settled this thinking now is. For most SMEs the question stopped being whether to move some time ago. It is how to move without breaking what already works.
How Does an AWS Migration Actually Run?
In five stages, and a credible AWS Partner UK will walk all five with you rather than handing you a plan and leaving. The sequence matters more than the speed: most failed migrations go wrong at the assessment stage and only reveal it at cutover, when the dependency nobody mapped brings down something unrelated.
Assess and plan. An honest audit of applications, dependencies, data volumes, licences and compliance obligations. The AWS Cloud Adoption Framework is a structured way to frame it across business, people, governance, platform, security and operations. The output should be a costed plan you keep, not a sales document.
Choose a strategy per workload. AWS groups the options into six approaches, usually called the 6Rs. Most SME migrations are a mix, and the skill is matching each workload to the right one.
| Approach | What it means | When it fits |
|---|---|---|
| Rehost | Lift and shift, move it as-is | Speed matters and the workload is stable |
| Replatform | Small optimisations during the move | Quick wins available without re-architecting |
| Repurchase | Switch to a SaaS alternative | The software has a credible cloud equivalent |
| Refactor | Re-architect to run cloud-native | The workload is core and worth the investment |
| Retire | Switch it off | Nobody has used it in a year and nobody will |
| Retain | Leave it where it is, for now | Licensing, latency or compliance says not yet |
Build the landing zone first. Before anything moves, your partner sets up a governed AWS environment, often with AWS Control Tower, to create an AWS landing zone: accounts, networking, identity and security guardrails up front. Aligning it with NCSC cloud security guidance keeps the design defensible to an auditor, and it is far cheaper than retrofitting cloud security later.
Migrate in waves, then cut over. Workloads move in groups, validated against the original and run in parallel where possible. A measured cutover beats a big-bang weekend every time, and it is the stage where real cloud migration experience earns its keep.
Optimise and operate. Go-live is the start. Regular cost reviews, security hardening and resilience testing are what turn a project into a capability.
How Do You Choose the Right AWS Partner UK?
Look past the logo at four things: the AWS tier, where the engineers actually sit, the security credentials, and whether there is a documented way out. The last one gets skipped most often and matters most, because a partner who will not write an exit path into the contract is telling you something.
UK-based engineers and the London region (eu-west-2) matter for more than latency. Data residency is simpler to evidence under UK GDPR when the processing never leaves the country, and a good partner documents that as part of the design rather than as an afterthought.
On credentials, ISO 27001 and Cyber Essentials Plus are the baseline worth insisting on. Ask to see them rather than taking the website’s word, and check they are current.
Then ask for proof at your size. Transputec helped events business IQPC restructure its AWS estate and the saving now runs to over $1 million a year, set out in our AWS cost optimisation case study, and the partner overview lists the full credentials. Two references at your scale and in your sector will tell you more than any case study.
What Happens After Go-Live?
The part most migration quotes go quiet about. A workload that has been lifted into AWS without anyone tuning it afterwards will cost more than the server it replaced, which is how cloud migration earns its reputation for overspending. The engineering that controls the bill happens after the move, not during it.
Expect regular cost reviews, security hardening and resilience testing as a standing commitment rather than a project phase. Transputec’s typical saving on AWS consumption after quarterly FinOps reviews is around 30%, enough to pay for the management fee several times over. Those reviews cover reserved instance and savings plan planning, right-sizing, and clearing up resources nobody is using.
Ask what the reporting looks like before you sign. Monthly reporting your finance team and your auditor can both read is a reasonable expectation, and a partner who cannot produce an example is unlikely to start once the contract is signed.
What Does It Cost and How Long Does It Take?
Most SME migrations run in phases over several weeks rather than months, and the honest answer on cost is that it depends on the estate rather than on a price list. What you can pin down before committing is the shape of the engagement, and that is what to compare between suppliers.
Ask whether AWS funding applies. The Migration Acceleration Program can offset a meaningful part of a complex move, and an AWS Partner UK at Advanced Tier can access it directly. A partner who does not raise funding unprompted may not have it.
Then separate the three numbers: the one-off migration cost, the ongoing AWS consumption, and the management fee. Quotes that blend them are hard to compare and harder to hold anyone to.
Your Checklist Before You Appoint an AWS Partner UK
Work through these before you sign anything.
- Confirm the current AWS tier and the path it sits on, not a historic badge.
- Ask who writes the landing zone design and who runs the cutover. Get names.
- Check where the engineers are based and which AWS region your data will sit in.
- Ask to see the ISO 27001 and Cyber Essentials Plus certificates, and check the dates.
- Get the exit path in writing before you start, not at renewal.
- Ask whether AWS migration funding applies to your move.
- Separate migration cost, AWS consumption and management fee in the quote.
- Ask for two references at your size and in your sector.
Conclusion
Moving off ageing on-premise hardware swaps a capital-heavy, fragile setup for infrastructure you can scale, recover and budget for. The route is well understood: assess, pick the right approach per workload, build a secure landing zone, migrate in waves, then optimise and operate.
The decision that actually changes the outcome is who walks it with you. An AWS Partner UK at Advanced Tier brings the methodology, the security baselines and the cost discipline an internal team rarely has spare capacity to build. Transputec does that work through AWS managed services, with named UK architects accountable for the result. Talk to us about the work behind your migration.
FAQs
What Is an AWS Partner UK?
A UK-based company accredited by Amazon Web Services to sell, build and manage AWS cloud services. Partners hold tiers that reflect proven delivery, and a services partner handles architecture, migration, security and day-to-day operations on your behalf rather than just reselling capacity.
What Is the Difference Between an AWS Reseller and a Services Partner?
A reseller provisions accounts and passes through your AWS billing. A services partner does the engineering: landing zone design, the migration itself, security baselines and ongoing operations. Ask who runs the cutover and who answers out of hours, because that is where the two separate.
How Long Does an AWS Migration Take for an SME?
It depends on the size and complexity of the estate, but many SME migrations move in phases over several weeks rather than months. A phased, tested cutover protects production, which is why an experienced partner plans the move in waves rather than a single switchover.
Will My Data Stay in the UK After Migrating to AWS?
It can. AWS operates a London region, eu-west-2, so a well-designed landing zone keeps data and processing within UK borders, which simplifies UK GDPR and sector compliance. A good partner documents data residency as part of the design rather than leaving it to be assumed.
How Do I Check an AWS Partner's Credentials?
Ask which tier they hold today and on which path, then verify it rather than taking the website’s word. Add ISO 27001 and Cyber Essentials Plus certificates with current dates, UK-based named architects, and a documented exit clause. Those four separate a genuine engineering AWS Partner UK from a reseller.
