Direct Answer

UK software consulting from ClickMasters costs £120–£250/hour, typically structured as fixed-scope engagements: Technical Discovery (£3,500–£8,000), Architecture Review (£5,000–£12,000), CTO Advisory (£2,500–£5,000/month), or Technical Due Diligence (£8,000–£20,000). The value of expert consulting: preventing £50,000–£500,000 of technical mistakes by spending £5,000–£20,000 on expert assessment before committing to the wrong architecture, the wrong vendor, or the wrong approach.

What Technical Discovery Includes

The most valuable sentence in a Technical Discovery: "the cheapest fix here is to change direction now, not in 12 weeks." ClickMasters has a financial incentive to recommend build — our consultants are instructed to recommend the right approach, even when that is a competitor, a SaaS tool, or no build.

Frequently Asked Questions

Common questions about uk software consulting guide (2025).

ClickMasters Technical Discovery: 4–6 weeks from kick-off. Week 1: stakeholder interviews and requirements workshops (product, technical, compliance). Week 2–3: architecture design and technical spikes (test specific technical approaches that are uncertain). Week 4: compliance assessment and risk register. Week 5: documentation and recommendation report. Week 6 (if needed): presentation to Board and iteration on recommendations. Deliverable: Technical Discovery Report (typically 25–40 pages), architecture diagrams, compliance gap analysis, risk register, and optional fixed-price build proposal.

In ClickMasters' experience: every Technical Discovery that identified a significant architectural error, compliance gap, or direction change paid for itself within the first 4 weeks of build. Examples: Discovery identified that a HealthTech platform needed DTAC Domain 2 compliance — adding this before build cost £4,000 additional. Retrofitting DTAC Domain 2 after the first failed assessment cost the next client £18,000. Discovery identified that a FinTech platform needed FCA PS21/3 multi-AZ architecture — designing this in cost £6,000 in Discovery. The comparable client who did not do Discovery spent £35,000 retrofitting resilience after their first FCA operational resilience review.
