Custom software development london teams can run inside their own working day: DigiWagon builds bespoke platforms for London companies from Ahmedabad, four and a half hours ahead, with UK GDPR designed in from the first diagram, the FCA’s outsourcing and resilience expectations understood, and a record of shipping AML, screening and lending platforms under audit.
This is the London version of our custom software development practice — the bespoke software development london buyers ask for is the same discipline, on the parent page. What changes here is the regulatory map, contracting and VAT, residency, and which of our work transfers.
Talk to us about a London buildHow we work here
Four things a software development company london buyers ask first.
London is four and a half to five and a half hours behind Ahmedabad, so your nine o’clock is our afternoon and our day runs into your early afternoon. Stand-ups, reviews and decisions happen live in your hours every working day; incident cover is agreed in the contract, not assumed.
You contract with DigiWagon Technologies Private Limited in India under a master agreement with statements of work, IP assignment on payment and an NDA before discovery, invoiced in GBP or USD. Services from a non-UK supplier are reverse-charged for VAT by a UK business; your advisers confirm that and anything an R&D claim needs, and we supply the documentation.
Every personal-data flow is mapped in discovery and the platform designed to UK GDPR and the Data Protection Act 2018 — lawful basis, retention, international transfer arrangements for the work we do from India, UK-region hosting where you or your customers require it — with the record kept for your DPO.
Fortnightly increments into your environment, every decision recorded, ISO/IEC 27001 and ISO 9001 controls applied to our side — so an FCA outsourcing question, an operational-resilience review or a customer’s due diligence can be answered from records.
What we build here
The bespoke work London teams commission most — a software development agency london firms would call it; we call it a build partnership — each row exiting to its practice page.
01
Onboarding, KYC, screening, monitoring and lending platforms for banks, payment firms and FinTechs answering to the FCA and the PRA — built to UK rules and hosted where your contracts and the regulator require.
02
The systems a London business runs on — operations, case management, client portals, reporting — replacing spreadsheets and off-the-shelf tools that never quite fit, with finance, CRM and HR integrations that reconcile.
03
Multi-tenant products for UK enterprise and public-sector buyers — tenancy that keeps UK data where the contract says, WCAG 2.2 AA built in, and the evidence procurement asks for.
04
Legacy estates — the .NET Framework system finance depends on, the vendor platform nobody can change — brought onto current stacks in stages, the business running throughout.
The market's own rules
The laws, regulators and standards that bind bespoke software built for London companies, and the rows above each one touches.
01
Lawful basis, impact assessments, retention, individual rights and the transfer arrangements for work done from India — mapped in discovery, designed in and recorded for your DPO.
02
Outsourcing and third-party risk expectations for regulated firms, and the resilience regime that asks how important business services survive a vendor’s failure — our controls and exit provisions answer those questions.
03
Public-sector bodies must meet WCAG 2.2 AA under the 2018 regulations and private firms owe reasonable adjustments under the Equality Act; we build to AA and test with assistive technology.
04
Eligible development may attract R&D relief under the merged scheme; services from a non-UK supplier are reverse-charged for VAT by a UK business. Your advisers rule on both; we keep the records a claim needs.
Discovery settles each of these with your counsel and your compliance lead before the architecture is drawn.

FAQ
Direct answers to what London teams ask before a bespoke software engagement.
Less with us than with a London-based team for the same delivery, because the cost base is Indian and the standard is not. The drivers are integrations, regulatory regime, throughput and audit needs, legacy migration and how much of the run you hand over. We scope those in discovery and give the estimate with its assumptions in conversation.
For the moments that need a room — discovery workshops, milestone reviews, launches — yes, we travel. The day-to-day is remote in your hours: London’s morning and early afternoon fall inside our working day, so stand-ups, reviews and decisions happen live, and incident cover is agreed in the contract rather than assumed.
Off-the-shelf software is built for a market and configured for you; bespoke software is built for your process, your data and your rules. Off-the-shelf wins when your need is common and your process can bend; bespoke wins when the process is your advantage, the integrations are yours alone, or a regulator asks for control you cannot buy.
With the transfer arrangements the law provides — the UK’s international data transfer agreement or addendum, a data-processing agreement, and access controls that keep production data in your environment where possible — plus a data-protection impact assessment where the processing warrants one. Your DPO gets the record; we design to it.
Yes: the controls, records, audit access and exit provisions the FCA’s SYSC 8 and the operational-resilience regime expect of a technology vendor are part of our standard agreement, backed by ISO/IEC 27001 and ISO 9001. Your compliance function keeps the register; we supply what it needs, on a schedule.
Support is a cadence: monitoring your team can read, scheduled patching, incident response within the agreed window and a quarterly review of cost, performance and security posture. Documentation and runbooks are handed over from the first release, so you can run it, hand it to your own team or leave it with us.
We will show you comparable regulated builds and the UK decisions behind a project before anything is scoped.
