NHS Video Consultation Software — Built to the Evidence NHS Buyers Check.

It designs, builds and integrates the software NHS clinicians and patients use for remote consultations: the real-time video, web and mobile apps, patient identity, and links to patient-record and scheduling systems. It also produces the clinical-safety and data-security evidence NHS buyers review before deployment. Trembit specializes in the real-time video layer, down to the WebRTC protocol, and builds that evidence alongside the code.

If it’s going into the NHS, expect it to. The Digital Technology Assessment Criteria are NHS England’s baseline for digital health technologies. NHS adopters review a supplier’s completed DTAC during procurement, across clinical safety, data protection, technical security, interoperability, and usability and accessibility. An updated DTAC form replaced the previous version by April 2026. We engineer so the evidence each area needs already exists when the form arrives.

The Data Security and Protection Toolkit is NHS England’s online self-assessment against the National Data Guardian’s 10 data security standards, and all organisations with access to NHS patient data and systems must use it. We build platforms with DSPT-aligned controls: encryption, access control, audit logging and incident response.

Yes, if your DPIA or buyer requires it. Residency is an architecture decision: hosting region, where TURN relays and media servers run, where recordings and logs are stored, and which third-party services touch the media path. We’ve built to strict residency before: our KBV-certified psychotherapy platform runs on Germany-only infrastructure with no third party routing the media.

Yes, where your service is eligible. NHS login is NHS England’s patient identity service, built on OpenID Connect, with verification levels up to P9 for services that need high identity assurance. Eligibility and onboarding are set by NHS login, not by the developer, so we check that early and design identity and step-up verification into the architecture from the start, rather than adding them at the end.

Yes. We integrate video consultations with patient-record and scheduling systems using FHIR R4 (including UK Core) and HL7 v2, so appointment context flows in and consultation outcomes flow back without re-keying. We’ve built one-click launch and session write-back into Epic and Oracle Cerner for US health systems. National GP-system access routes have their own onboarding rules, which currently vary by API, so we confirm the open route for your product before committing a design.

Trembit LLP is a supplier on the NHS PiP Non-Clinical Systems Dynamic Purchasing System (NOE CPC) in the Video Consultation sub-category, so NHS organisations running a further competition under that DPS can invite us to bid. We also respond to trusts’ own procurements as a UK-registered LLP.

Under DCB0129 the manufacturer of a health IT system needs a Clinical Safety Officer, and under DCB0160 the deploying NHS organisation needs its own. When you’re the product company, the manufacturer CSO is yours: we maintain the hazard log with them and build the controls the safety case relies on, but we don’t sign it.

A lot of the engineering carries over: encryption, access control, audit trails. The obligations don’t. The NHS asks for DCB0129 clinical risk management with a hazard log and safety case, DSPT-aligned data security, UK GDPR evidence for the buyer’s DPIA, DTAC, and often NHS login and FHIR UK Core integration. We start with a gap review against those standards, then fix the architecture rather than the paperwork.

There’s no fixed price; cost follows scope. The main drivers are integration depth (NHS login, EPR, GP systems), the number of apps, recording and UK residency requirements, the clinical-safety evidence scope, and peak concurrency. The first step is a free 30-minute architecture call, and we give a firm estimate after a scoping call.

You do. All source code, documentation and intellectual property we create for you transfer to you. For work commissioned by an NHS organisation through a DPS call-off, NHS standard contract terms apply, including the buyer’s licence to use and adapt what we deliver.
