United Kingdom
Software Development Agency for UK Businesses
GridCore builds custom software, MVPs, SaaS platforms and AI automation for UK companies with a senior-only engineering team working London hours. MVPs start from around £3,100 (billed at $4,000 USD or in GBP), embedded senior engineers from about £1,200 per month, and every engagement is month-to-month with full IP transfer and UK GDPR-aligned data handling.
UK founders and operations leads usually reach us after a London agency quote in the tens of thousands of pounds, or after a contractor stopped answering. GridCore gives you a senior team working your hours at a fraction of the cost, without the risk profile of one-person freelancing.
Engineers work full UK business hours (GMT/BST), join your stand-ups, and communicate in your Slack or Teams. IR35 is not a concern: you engage GridCore as a company on a services agreement, not an individual contractor.

Questions from United Kingdom clients
Do you sign a Data Processing Agreement for UK GDPR?+
Yes. We sign a DPA with UK GDPR and Data Protection Act 2018 clauses, follow least-privilege data access and can keep production data inside UK or EU regions on your cloud account.
Is engaging GridCore inside or outside IR35?+
Outside. You contract with GridCore as a company on a services agreement with deliverables, not with an individual in a role. This is the standard model for agency engagements.
What hours do your engineers work for UK clients?+
UK clients get a full working-day overlap with London (GMT/BST), including stand-ups and same-day responses in Slack or Teams.
How much does a software development agency cost in the UK?+
London agencies typically charge £80-£150 per hour and £30,000-£100,000+ for an MVP. GridCore fixed-scope MVPs start around £3,100 and full-time senior engineers are about £3,100 per month, with the same seniority.
Can you work with an existing UK development team?+
Yes - team augmentation is our most common UK engagement. Engineers embed in your repo and process within a week, month-to-month, scaling up or down with two weeks notice.
Do you serve Ireland as well?+
Yes. Irish clients get the same model with EU GDPR-aligned processing and EUR or USD invoicing.
