Planning service
How the planning service works
Through Technology has in-depth expertise and experience in managing legacy technology risk in central government, working collaboratively with internal teams and third-party suppliers. Our process starts with a current state assessment where we identify legacy systems in your estate and assess both their business criticality, security/service and impact to other initiatives and digital transformation. This enables prioritisation of your legacy risks and supports creation of a business case to address the issues. We will then look at each system in turn, helping build a strategic approach to address technical debt through our 6 R's: Risk manage, Retire, Replace, Rehost, Replatform, Refactor. The outcome is a pragmatic, justifiable roadmap and business case to reduce your organisations technical debt and legacy risk. Both the development and implementation of this strategy can be undertaken solely by us, or led by us working openly and collaboratively with your internal teams and third-party suppliers. During any transition we work closely with your existing support teams and toolsets, providing early life support and knowledge base article material to ensure a smooth cutover.

Training service provided
How the training service works
We provide training as part of our migration and support services. This includes training of 1st and 2nd Line Support to reflect changes during migration and with the target solution, provision of knowledge base articles and providing end user guidance, communications and training material. Our aim is to transfer knowledge to our customers such that your organisation (or replacement supplier) can operate effectively once the project has concluded. We have a defined exit and knowledge transfer approach to ensure this is the case and tailor it to meet any specific customer requirements. Our company culture is one of open direct knowledge-sharing and this is embedded in our teams. Where required we can engage in upskilling customer teams to reflect the new requirements of modernised legacy systems.
Training is tied to specific services

Setup and migration

Setup or migration service available
How the setup or migration service works
Re-hosting, Re-platforming or refactoring a workload to move to the cloud (or between cloud platforms) is one of the options we consider for legacy systems. We will evaluate this based upon business criticality, risk, performance, compatibility and other key factors. Where cloud is not a viable target, we may recommend moving to Crown Hosting in accordance with the Digital Data and Technology Playbook. If a cloud service is the best option for your business and it's system, we will work independently or with internal teams or third-party incumbent suppliers to recommend a target system aligned with your strategy and define the most appropriate re-hosting, re-platforming or refactoring approach. If required we will then design and plan the migration approach, undertake its implementation and provide early life support integrating into your existing service model.

Quality assurance and performance testing

Quality assurance and performance testing service
How the quality assurance and performance testing works
We are experts in quality assurance and have extensive experience in solution, security and delivery assurance for UK Public sector organisations. Where third-party suppliers are involved, we can objectively assess their detailed strategy and approach for modernisation of any system and address issues in quality, security, viability, risk, pricing, performance and deliverability. For any modernisation we undertake, we will apply the same standards and ensure a robust scenario-based test strategy is in place to ensure any that change does not result in unplanned outage, incident or service degradation. We will work within your defined change process or provide our own if required. Where required we will organise IT Health Checks with appropriately certified testers (or your own chosen provider) and ensure findings are addressed.

Fighting climate change

Fighting climate change

Through Technology is a Carbon Negative Business and formally assessed and certified as such with the PAS2060 Carbon Neutral Plus standard. This means that our services are operated to remove more carbon dioxide from the atmosphere than our business has created or will create in future, already significantly exceeding HM Government's Net Zero targets. Our business was designed with a very carbon-efficient business model. Building on this foundation, we have a process of continual improvement. We annually calculate our carbon footprint using the reputable service, identify further reductions in our environmental impact, then offset -double- the residual carbon footprint of our business through the same scheme reputable UK tree-planting scheme used to offset HM Government ministerial travel. Measuring our footprint every year, optimising it and offsetting double, scales with our business and automatically applies to every service we provide (through G-Cloud or elsewhere). Furthermore, because trees last for many years, our positive impact on carbon capture and storage will continue to grow greater and greater across the lifetime of our business. As a business, we are also focussed upon helping our customers achieve your outcomes. We consider environmental impact in the work we undertake as part of our services many of which involve carbon reduction through modernisation of systems and migration to the cloud. Fighting Climate Change is something we are passionate about. We are proud of the contribution we make as UK Small Business. It also shows our commitment to not only meet, but exceed government targets for fighting climate change and goals of Procurement Policy Notes PPN 06/20 (Social Value) and PPN 06/21 (Taking account of Carbon Reduction in major contracts).

Covid-19 recovery

Covid-19 recovery

In Through Technology, we have a very strong focus on achieving value for the tax-payers money and on supporting the UK economy. We are a UK Small Business, paying all our taxes in the UK and operating in full compliance with UK Tax regulations. We are members of the TechUK industry body, volunteering time via our seat on their Justice and Emergency Services Committee to help to define and deliver best practice in work between the Digital & Technology industry and government. We are signatories to the UK Government Small Business Commissioner’s Prompt Payment Code. Meaning we commit to paying our supply chain within 30 days and have never yet failed to do so, even when we ourselves have faced delays in our payments. Our company principles include sharing knowledge and building capability with our customers’ internal teams. This can be seen in our “Insource Transition Support” service published on G-Cloud. Helping our customers insource and develop their internal teams will drive upskilling and job creation within our public sector customers. We have a defined standard business process to actively seek out opportunities for savings and cost avoidance for our customers in everything we do. This process has resulted in savings and cost avoidance of over £10M in the last 3 years, saving our customers more than we have cost them while we have also delivered all of our contracted scope. We have also created new jobs in our business during the Covid 19 pandemic and continue to collaborate effectively with our customers remotely through their choice of tooling and onsite following all current Covid guidance.
Tackling economic inequality

Tackling economic inequality

Through Technology are committed to fighting economic inequality. As a modern business without strong geographic ties, our hiring policy is to prioritise recruitment from areas of high social deprivation as identified in the Department for Levelling Up, Housing and Communities' English Indices of Deprivation). At present, 40% of our staff are from these areas and as our business grows, so will this percentage, ensuring that most of the tax-payer money spent on our services ends up in the local UK communities that need it the most. We are an equal opportunities employer that recognises and actively seeks out the benefits of diverse and inclusive teams to our business, to our customers and to wider society.
Equal opportunity

Equal opportunity

We are an equal opportunities employer that recognises and actively seeks out the benefits of diverse and inclusive teams to our business, to our customers and to wider society. This is built into our policies, procedures and contracts, and lived day to day. We have worked to remove any bias from our organisational processes, including subconscious bias where it may exist. An example is that the first stage of our recruitment process is anonymised, minimising the impact of any potential bias in CV and Application evaluation. We are signatories to the Armed Forces Covenant and seek proactively to recruit ex-forces personnel, overcoming some of their challenges in returning to civilian life. Our recruitment process for opportunities is intentionally designed to be accessible and open to all. Our teams working through G-Cloud are diverse and include people from different parts of the UK, age groups, ethnic origin, gender, disability and faith.


Through Technology’s defining characteristic is the quality of our people, so we take well-being very seriously and have a number of measures in place to support the well-being of our staff and people they work with. Despite our relative small size, we have a board member responsible for staff wellbeing and a number of policies and processes which we live every week to maintain it. Examples include: Providing private health cover for all employees, offering time out for voluntary work in our local communities (including current staff acting as school governors, volunteering careers guidance in schools, acting as community representatives and teaching practical philosophy/life skills), funding a qualified Mental Health First Aider within the business, fostering a culture that welcomes private or public discussion of mental health and well-being (including open discussion of our CEO’s personal experiences). We also care about the well-being of those we work with in our supply chain, our customers, and their third-party suppliers. If we identify any well-being or stress-related issues with colleagues outside our organisation, then we handle these sensitively through the appropriate process or channel.
