About us
A consultancy centred on structure, not slogans
IT ARCH SOLUTIONS LT is a United Kingdom company engaged in information technology consultancy activities. We work with leadership teams, CIO offices, and programme directors who need disciplined thinking about how technology supports strategy — whether they are consolidating legacy estates, launching new digital products, or preparing for regulatory change.
Our name reflects what we believe matters most: architecture — the deliberate arrangement of applications, data, infrastructure, security controls, and operating models so that change remains coherent over years, not just sprints. We are not a body-shop for generic resource augmentation; we are advisors who help you decide what to build, what to buy, what to retire, and how to govern it.
Based at our registered office in Bexleyheath, Kent, we serve clients throughout London, the South East, and nationally. Engagements are delivered through a blend of on-site workshops, remote design sessions, and structured documentation that becomes part of your organisational memory.
We favour transparent scope, explicit assumptions, and measurable exit criteria. When we recommend a path, we explain trade-offs, dependencies, and the skills your teams will need to operate the solution day to day.
Consultancy capabilities across the IT lifecycle
From discovery through transition, we provide advisory and hands-on architecture support tailored to mid-market and enterprise environments in the UK.
Enterprise & solution architecture
Develop target-state reference architectures, integration patterns, and solution outlines aligned to your business capabilities. We produce views that development teams, security, and operations can all use — avoiding shelf-ware diagrams.
- Capability and process mapping
- Application portfolio rationalisation
- API and event-driven design patterns
Cloud & infrastructure strategy
Assess readiness for public, private, or hybrid cloud; define landing zones, networking, and identity models; and plan migrations with realistic cutover sequencing. We emphasise FinOps, resilience, and operational runbooks from day one.
- Cloud adoption frameworks
- Migration wave planning
- Disaster recovery and BCP alignment
Data & analytics advisory
Clarify data domains, ownership, quality rules, and analytics pipelines. We help you move from fragmented spreadsheets and siloed warehouses toward governed data products that support reporting and machine learning responsibly.
- Data governance operating models
- Modern data platform design
- Metadata and lineage practices
Cyber security & risk architecture
Embed security into architecture decisions — zero trust principles, segmentation, privileged access, and secure SDLC — rather than bolting on reviews at the end. We translate NCSC-aligned guidance into actionable technical controls.
- Threat modelling workshops
- Security architecture patterns
- Third-party and supply-chain risk
Digital transformation & change
Support programme initiation, benefits realisation, and organisational design for digital initiatives. We connect technology roadmaps to process change, training, and service management so adoption sticks.
- Transformation business cases
- Operating model design
- Stakeholder and comms planning
Independent assurance & review
Provide second-line challenge on vendor proposals, in-flight programmes, or inherited estates. Our reviews highlight gaps, hidden costs, and architectural drift before they become production incidents or audit findings.
- Architecture maturity assessments
- Technical due diligence
- Post-implementation reviews
What sets our consultancy apart
Depth over buzzwords
We write specifications, decision records, and architecture principles in plain English. Stakeholders leave workshops understanding not only what was decided but why alternatives were rejected — essential for organisations subject to audit or public scrutiny.
Respect for in-house teams
Our role is to strengthen your capability, not create dependency. We pair with your architects and engineers, transfer patterns, and leave templates that match how you already document and deliver.
Pragmatic time horizons
Roadmaps distinguish quick wins, foundational investments, and optional futures. We avoid binary “big bang” vs “do nothing” framing and instead sequence work so funding and capacity stay credible.
Commercial awareness
Licensing, support contracts, exit clauses, and internal chargeback matter as much as technical elegance. We help finance and IT jointly understand total cost of ownership over a realistic multi-year horizon.
Our approach
A five-phase engagement model
Discover. We interview sponsors, review existing documentation, and map the current landscape — applications, integrations, infrastructure, data flows, and pain points. Workshops surface constraints: regulatory, budgetary, skills, and contractual.
Define. Together we articulate outcomes, principles, and non-negotiables. We agree scope boundaries, success measures, and governance — who approves architecture decisions and how exceptions are handled.
Design. We produce target architectures, transition states, and option appraisals. Where appropriate, we run proof-of-concept spikes to validate risky assumptions before large spend is committed.
Deliver. We support procurement, RFP evaluation, and supplier selection with weighted criteria tied to your architecture. During build, we act as design authority — reviewing significant changes and preventing unmanaged drift.
Develop. After go-live, we help institutionalise monitoring, continuous improvement, and periodic architecture reviews so your estate evolves deliberately rather than by accretion alone.
Sectors we frequently advise
While our methods are sector-agnostic, we bring contextual knowledge of regulatory pressures, typical system landscapes, and integration ecosystems common in these UK markets.
Financial services & insurance
Banks, insurers, and fintech scale-ups face heightened expectations around resilience, outsourcing registers, and customer data handling. We help align architecture with FCA/PRA themes, operational resilience testing, and legacy core modernisation without compromising audit trails.
Public sector & education
Councils, NHS trusts, academies, and arm’s-length bodies must demonstrate value for money and transparency. We design solutions compatible with public cloud frameworks, identity federation, and accessibility standards while respecting tight capital cycles.
Professional services
Law firms, consultancies, and accountancy practices need secure collaboration, matter-centric workflows, and client confidentiality. We architect Microsoft 365 or Google Workspace estates, DMS integrations, and client portals with appropriate information barriers.
Retail, hospitality & logistics
Omnichannel estates combine POS, e-commerce, WMS, and loyalty platforms. We address peak-traffic resilience, PCI considerations, and real-time inventory visibility across franchise or franchise-like operating models.
Manufacturing & engineering
OT/IT convergence, ERP extensions, and shop-floor data collection require careful segmentation. We plan edge connectivity, MES integrations, and analytics without exposing industrial systems to undue cyber risk.
Technology & scale-ups
High-growth product companies need architecture that supports rapid feature delivery without re-platforming every year. We introduce lightweight governance, platform teams, and observability practices suited to venture-backed timelines.
Technology landscape
Platforms and patterns we work with daily
We remain vendor-neutral while maintaining hands-on familiarity with ecosystems our clients already use or are evaluating.
Cloud & platform
Microsoft Azure, Amazon Web Services, Google Cloud Platform, VMware, and Kubernetes-based platforms. Landing zone design, identity (Entra ID, IAM), and infrastructure-as-code using Terraform or Bicep.
Integration & applications
REST and GraphQL APIs, enterprise service buses, iPaaS (MuleSoft, Boomi, Logic Apps), and microservices on .NET, Java, or Node. ERP and CRM packages including SAP, Oracle, Microsoft Dynamics, and Salesforce.
Data & AI
SQL and NoSQL stores, lakehouse patterns on Databricks or Synapse, streaming with Kafka or Event Hubs, and responsible adoption of copilots and ML services with governance guardrails.
Operations
ITIL-aligned service management, DevOps toolchains (Azure DevOps, GitHub Actions, Jenkins), observability with Datadog, Splunk, or native cloud monitoring, and ITSM platforms such as ServiceNow.
Illustrative engagement outcomes
The following anonymised scenarios reflect the types of challenges we address. Client names are withheld for confidentiality.
Regional insurer — core policy administration renewal
Over eighteen months we co-led an architecture workstream for replacing a twenty-year-old policy admin suite. Deliverables included a canonical data model, phased strangler-fig migration, and a £14m business case scrutinised by the board. The programme achieved first production slice on schedule with zero unplanned downtime during peak renewal season.
London borough — shared services cloud exit
Following datacentre closure notices, we assessed 240 workloads and classified them into rehost, replatform, or retire buckets. A hybrid Azure estate with mandated encryption and backup policies was approved by information governance. Year-one run-rate savings of 22% funded reinvestment into cyber tooling.
B2B SaaS provider — platform team inception
We defined platform boundaries, golden paths, and internal developer portal requirements for a 120-engineer product organisation. Time-to-production for new microservices dropped from six weeks to nine days while maintaining SOC 2 control objectives.
What leaders say about working with us
“They translated a contentious ERP upgrade into a decision framework our CFO and CIO could both sign. No slide-deck theatre — just clear options, costs, and risks.”
“Our internal architects were sceptical of external consultants. IT ARCH SOLUTIONS LT earned trust by documenting alongside us and defending our standards in supplier negotiations.”
“The post-implementation review was as valuable as the upfront design. We finally have a living architecture repository tied to our change advisory board.”
FAQ
Common questions
How do engagements typically start?
Most clients begin with a short discovery call and, where helpful, a fixed-fee diagnostic (one to three weeks) to validate scope. We then propose a statement of work with deliverables, cadence, and assumptions explicit.
Do you implement solutions or only advise?
Our registered activity is consultancy. We focus on architecture, strategy, and assurance. Implementation is usually performed by your teams or delivery partners we help you select and govern — we do not position ourselves as a reseller or MSP.
Can you work under client security policies?
Yes. We routinely operate under NDAs, cleared laptop policies, and client-provided collaboration tools. Data minimisation and UK/EU hosting preferences are respected by default.
What engagement sizes do you support?
Assignments range from executive workshops and targeted reviews to multi-year transformation advisory. We scale team shape — lead architect plus specialists — to match complexity without inflating headcount unnecessarily.
Where are you based?
Our registered office is at 60 Barrington Road, Bexleyheath, Kent, DA7 4UW. We meet clients across London and the UK, with remote delivery available for distributed stakeholders.
Perspectives on UK IT architecture practice
Why architecture review boards fail — and how to fix them
Many ARBs become ticket-chasing forums because they lack decision rights, principles, and published standards. We outline a lightweight governance model that preserves delivery speed while catching high-impact drift early.
