UK-hosted low-code platforms compared (2026)

The short answer. “UK-hosted” means one of three things, and they are not the same. A global platform running in its UK cloud region keeps your data in the UK but runs on the vendor’s terms. A UK vendor hosting in UK data centres adds a UK company that answers for it. A platform you can run in your own tenancy or on your own servers keeps everything inside your boundary. Toca, the platform we build, is a UK company and gives you three ways to run it, chosen for each deployment: in Toca’s own UK cloud, in your own cloud, or on your own servers, air-gapped if you need it. Of the others, Power Platform offers the first kind, Responsiv the second, and n8n and Responsiv’s self-hosted product the third. Decide which kind your data actually needs, and then check the vendor’s G-Cloud listing or contract, not just its website.

The three kinds of UK hosting

The difference matters because each kind answers a different question from the people who look after your data, and a vendor that says “UK-hosted” may mean any one of them.

Kind	What you get	What to check	Fits
A global cloud’s UK region	Data stored and processed in the UK, on the vendor’s global platform	Which features or AI services can move data outside the UK, and who can switch them on	Most commercial work where UK residency is enough
A UK vendor in UK data centres	UK residency, plus a UK company running the service	The data centres’ certification, the sub-processors, and whether you can choose location	Public sector and regulated work that wants a UK supplier
Your own tenancy or servers	Nothing leaves your boundary; you control the infrastructure	Which product and plan allow self-managed deployment, and who patches it	Health, legal and financial work where data cannot leave the building

Toca gives you three ways to run it, which between them cover the second and third kinds. It runs in Toca’s own UK cloud, in your own cloud, whether that is Azure, AWS, Rackspace or a dedicated server, or on premises. You choose for each deployment, and they work together. Toca’s agent bots sit inside your network and connect outbound to the Toca server, needing only internet access and an entry on your allow-list, so a process running in Toca’s UK cloud can still work with a legacy case management system that is hosted on premises.

The platforms

These are the platforms that come up when UK buyers ask. Each is described from the vendor’s own published information or G-Cloud listing on 11 November 2026.

Platform	What it is	UK hosting, as published	Choose it when
Toca	UK-hosted low-code automation, integration, apps and document AI (Spectral)	Toca’s UK cloud, your own tenancy, or your own servers, air-gapped if needed	You have regulated, high-volume processes across several systems, with documents read and a person deciding
Microsoft Power Platform	Low-code apps, automation and RPA in Microsoft 365	Microsoft’s cloud in the region you choose, the UK included; on-premises systems reached through a gateway	You are on Microsoft 365 and the work is team-level
Responsiv	UK integration and automation platform	Responsiv Cloud in ISO 27001 certified UK data centres; Responsiv Unity self-hosted	The work is integration-led and you want a UK specialist, managed or self-hosted
n8n	Workflow automation with an open, self-hostable core	Self-host it anywhere, including your own UK infrastructure; or its cloud	Your technical team wants to run and extend workflow automation itself
Mendix, OutSystems	Enterprise low-code application platforms	Vendor clouds, or self-managed on the products and plans that allow it	You are building a portfolio of complex applications with your own developers

Two phrases in the third column deserve a second look. “In the region you choose” describes a vendor’s global platform, which runs on the vendor’s terms. “On the products and plans that allow it” means self-hosting may not be on the plan you were quoted, so check the current terms before you shortlist. With Toca the choice is made for each deployment, and it includes your own servers.

How Toca does it

Toca is a UK company. The platform runs in Toca’s UK cloud, in your own cloud tenancy or on your own servers, air-gapped if the data cannot leave the building, and you choose for each deployment.

The platform brings apps and portals, automation and integration, using APIs where they exist, RPA where they do not and C# when neither is enough. Its document AI, Spectral, reads documents with more than one model and sends any disagreement to a person, and its models can run inside your boundary. Toca holds ISO/IEC 27001, ISO/IEC 42001 and Cyber Essentials Plus, Spectral is UKCA-marked as a Class I medical device, and both the platform and Spectral are listed on G-Cloud 15.

It is in production at scale. Toca runs around 276,000 workflows a day, among them eTriage across NHS trusts, claims work for UK volume law firms and payroll for around 1,750 schools at EPM.

Customer	Work	Result
NHS trusts	eTriage: the referral, patient record and decision on one screen	15% of England’s population will have their GP referrals to secondary care handled through eTriage
Winn Group	Repair invoices and the claims lifecycle	Around 160 hours of staff time returned every month
Bond Turner	Credit hire rate rebuttal reports	Up to 80% lower cost per report
JMK Solicitors	Key dates on personal injury files	25% fewer files at risk of write-off
EPM	Payroll and pensions as a managed service	Payroll for around 1,750 schools, academies and trusts

It is priced per workflow, not per seat. In NHS acute and general hospitals that is typically £1 per referral, with no other costs, and for law firms it is £30,000 to £150,000 a year as a guide, depending on how many workflows they run and how many users and apps they have.

Hosting is where a shortlist starts, and the platform still has to do the work once it is there. For the law firms that have come to us from Power Platform, where it was hosted was the lesser problem. The greater one was how hard a complex app had become to maintain, and how much work it had to carry. We have set that out in Power Platform alternatives for regulated, high-volume work, and row by row on Toca and Power Platform.

If you need a platform that stays in the UK or inside your own boundary, talk to us. We will spend twenty minutes on where your data has to live and what the process has to do, and then show you one step of it running end to end, with the sign-off and the audit trail in view. There is more on the platform and on our certifications.

What to ask every vendor

These seven questions sort a shortlist, and we have given Toca’s answer to each.

1. Where exactly is my data stored and processed, and can I choose? A vendor’s G-Cloud listing answers both in a standard form. With Toca it is in the UK, and you choose between Toca’s UK cloud, your own tenancy and your own servers for each deployment.
2. Can any feature move data outside the UK? AI features are the usual exception. Microsoft, for instance, says some generative AI features can process UK data outside the UK once an administrator allows it. Spectral’s models can run inside your boundary.
3. Can it run in my own tenancy or on my own servers, and on which plan? “Self-managed is available” often turns out to mean a particular product or tier. Toca runs in your own tenancy or on your own servers, air-gapped if the data cannot leave the building.
4. Who are the sub-processors? A UK data centre run under a non-UK parent may still matter to your DPIA. Toca is a UK company.
5. What is certified? Look for ISO 27001 for the service and Cyber Essentials Plus, for health DSPT and the clinical safety standards, and for AI ISO 42001. Toca holds ISO/IEC 27001, ISO/IEC 42001 and Cyber Essentials Plus, and Spectral is UKCA-marked as a Class I medical device.
6. How does it reach systems with no API? Regulated work usually involves at least one, whether an old case management system, a portal or a desktop application. Ask whether it is reached by API, RPA or code, and who maintains it. On Toca all three sit in one workflow, and agent bots inside your network connect outbound to reach the systems you still host yourself.
7. What does it cost at your volume? Platforms charge per user, per bot, per app or per workflow, so model three years at your real numbers. Toca is priced per workflow, not per seat.

When to choose Toca, and when to choose something else

Toca is the stronger choice when:

• the data has to stay in the UK, in your own tenancy or inside your own building
• you want a UK company answering for the service
• the process is regulated and has to stand up to an audit
• it runs at high volume and crosses several systems, some of them with no API
• documents have to be read, with a person making the decision
• you want a cost that follows the work and is known in advance

Something else may fit better in these cases:

• Power Platform, if UK residency in Microsoft’s cloud is enough, the work is team-level and your people already have the licences.
• Responsiv, if the job is mainly integration and you want a UK specialist.
• n8n, if your engineers want to self-host and extend workflow automation themselves.
• Mendix or OutSystems, if you are building many complex applications with a large development team.

Questions

What does UK-hosted mean for a low-code platform?

It means your data is stored and processed in the UK, but that can be a global cloud’s UK region, a UK vendor’s UK data centres, or the platform running in your own tenancy or on your own servers. Ask which one, and whether any feature can move data elsewhere. Toca is a UK company and gives you three ways to run it: in its own UK cloud, in your own cloud or on your own servers.

Which low-code platforms can run on our own servers?

Toca can, air-gapped if the data cannot leave the building. Several others offer self-managed deployment, often on particular products or plans, including Mendix, OutSystems, n8n and Responsiv Unity. Check which features run self-managed, and not only that it is possible.

Is Power Platform UK-hosted?

It can run in Microsoft’s UK region. Systems on your own network are reached through the on-premises data gateway, and some generative AI features can process data outside the UK if an administrator allows it. If you need the platform itself inside your own boundary, Toca runs in your own tenancy or on your own servers.

What should a DPIA check about a low-code platform?

It should check where data is stored and processed, who the sub-processors are, which features can move data, what is certified and who can access production. G-Cloud listings state several of these in a standard form, and Toca’s G-Cloud 15 listings cover both the platform and Spectral.

Are there UK low-code platforms on G-Cloud?

Yes. Toca lists both its platform and Spectral on G-Cloud 15, and Responsiv lists services there too. Search the Digital Marketplace for “low-code platform” to see the current list.

What does a UK-hosted low-code platform cost?

It depends on the pricing model, which may be per user, per bot, per app or per workflow. Toca is priced per workflow, not per seat: typically £1 per referral in NHS acute and general hospitals, with no other costs, and £30,000 to £150,000 a year as a guide for law firms.
