Planning service
How the planning service works
Our service provides an end-to-end migration of email data to the cloud. Discovery activities will help quantify the migration and address key issues such as co-existence, shared mailbox consumption and licensing. Planning activities will work closely with the customer to define a migration schedule that minimises any potential business impact. We can work easily as part of a wider infrastructure migration programme, tying our activities into a wider migration schedule with other suppliers and processes. We will undertake or assist with infrastructure impact assessment and configuration of the target environment. Ensuring a performant end solution aligned with government security guidance. Migration approaches will be tailored to meet the customer needs for speed or transparency of migration. We will work closely with the customer to help create exciting, plain English, clear and concise business communications and engagement material. We are equally at home using our own Agile methodology and planning tools or fitting in with our customers' wider agile/hybrid/waterfall programme plans.

Setup and migration

Setup or migration service available
How the setup or migration service works
We have in-depth experience migrating email at enterprise-scale in UK Government. Including from multiple systems, in complex customers and with multi-supplier/disaggregated supply chains. We support migration and co-existence between public cloud solutions (e.g. Google Workspace and Microsoft Office 365), from private clouds and from on-premise solutions. We provide end-to-end service, from user research, requirements analysis and email platform selection, through to the decommissioning old email platforms. We undertake consolidation projects, migrating users from multiple cloud solutions to a single platform, reducing support costs and resolving poor user experience caused by multiple identities, mailboxes, and distribution lists. We configure email security controls and help customers establish processes to ensure email security is properly managed. All planning and scheduling is based around the business and user experience, including co-existence between systems, achieveable migration "beat-rate" from a technology, business, user and support perspective, and scheduling with consideration of key business events. We work with your teams providing clear, plain-English end-user guidance and support business engagement. We also provide migration support and early life support to ensure the best user experience, providing training and knowledge base articles for your service desk to ensure incidents are well managed and first time fix rates are high.

How the support service works
In addition to migration and early life support, we can provide ongoing email system support and security operations (SecOps), including but not limited to: 1st-3rd line end user support, SecOps, Monitoring, etc. Our support services are tailored to customer requirements with SLAs Scope and Service hours to meet your requirements. Even where no ongoing support is required, customers will have a named service manager who will respond to any queries raised after project completion and help organise any future assistance required.

Service scope

Service constraints
Any constraints will be customer specific and therefore identified during the call off contract proposal. Typically these will involve constraints resulting from your business requirements, existing email systems or incumbent suppliers. We have extensive experience managing such issues, so please raise any concerns with us at the outset.

User support

Web chat accessibility testing
We will typically use our customers' IT Service Management tooling or the chat software already in use within their organisation, such as MS Teams, Google or Slack. This avoids the complexity of introducing a new product to your users and Assistive Technology software.
Support levels
This is a migration engagement for which we would specify support levels in agreement with the customer, based upon their existing support capability and the required migration schedule and "beat rate".

We are equally at home using our own IT Service Management toolset or working with a customer's system (e.g. ServiceNow) where we need to fit within a larger service model.

Outside of migration activities, we offer user support services separately through our TT Cloud Services Support offering on G-Cloud lot 3.

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 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). Further detail, including "Beyond Net Zero - The Through Technology Environmental Impact Plan" available upon request.
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.
