Executive Summary
A SaaS dashboard built through a mid-market UK agency in 2026 lands between £22,000 and £75,000 depending on scope — with London shops pricing at the top end, Manchester/Bristol/Leeds around 20–30% lower, and Edinburgh/Belfast lower still. Day rates at competent mid-market product studios sit around £650–£900 in London and £500–£750 outside it. Add 20% VAT on top if you're not VAT-registered yourself.
The DIY route using the MyAppTemplates boilerplate ($199 / ~£155 one-time) plus Claude Code lands most SaaS dashboard scopes for £45–£180 in marginal AI spend over 3–8 days. That only works for founders comfortable shipping software themselves — it is not a like-for-like swap for an agency relationship, and it is not the right route if you're building regulated FCA-permissioned fintech.

1. UK agency rates — what you're actually paying for
A competent mid-market UK product studio in 2026 charges a £650–£900 day rate in London and £500–£750 outside it. That's 50th–75th percentile — not Shoreditch brand studios, not Big 4 digital. For a standard subscription SaaS with auth, workspaces, Stripe and a dashboard, a 6–10 week engagement at that rate lands you in the £30–£60k bracket before VAT. Add roughly 20–30% for London shops vs. Manchester, Bristol, Leeds.
Reality check
Where a £40k SaaS quote actually goes
Discovery & design~£6k–£10k (2 weeks of a PM + designer)
Backend + infra setup~£10k–£14k (auth, DB, Stripe, CI — the week the boilerplate removes)
Feature build~£14k–£18k (the bit you actually care about)
QA, handover, buffer~£4k–£6k
VAT on all of it+20% if you're not VAT-registered
When an agency is the right call
You should probably hire a UK agency if…
You're FCA-permissionedYou need a delivery partner with named engineers on SoW, PI insurance, and audit trails. DIY doesn't clear that bar.
You need procurement coverEnterprise buyers often require a UK Ltd supplier with references and insurance — a solo founder shipping with Claude Code fails vendor onboarding.
You don't want to touch codeAgencies own the outcome. DIY with a boilerplate assumes you'll be in the repo daily.
2. The DIY route with a boilerplate — what you skip, what you still build
The honest version: the boilerplate removes the first week of any SaaS build. JWT auth, D1 + Drizzle schema, Stripe adapter for subscriptions, RevenueCat adapter, rate-limited endpoints, Sentry, CI/CD, Expo mobile shell, theme system — all scaffolded. That's the part UK agencies bill as ~£10–14k of setup. Week 2 onwards is Claude Code building your actual SaaS features (workspaces, dashboards, webhooks) against working foundation.
MobileExpo Router, tabs, onboarding, paywall, profile, theme system
AI-native toolingAGENTS.md, CLAUDE.md, .cursorrules, Kilo subagents @backend-dev / @mobile-dev, slash commands like /new-feature
You still build this
Scope that lives on top of the boilerplate
Stripe Connect (marketplace payouts)Billing adapter accepts Connect — you wire the Connect integration. ~1 day with @backend-dev.
Real-time collaborationWorkers supports Durable Objects; you define the channel classes. 2–3 days with Claude Code.
Admin panelNot scaffolded — RBAC pattern and modular routes give you the skeleton; build the UI with /new-feature admin.
SSO (SAML / OIDC), SCIMExternal integration against the auth flow; rate-limiting and session handling already exist.
3. UK-specific notes: VAT, Stripe, FCA
Three things UK SaaS founders trip over regardless of route: VAT on agency invoices, Stripe's UK-vs-EU routing, and FCA scope for anything that touches regulated activity. Get these wrong and the software cost becomes a rounding error.
Three UK gotchas
Cost items outside the build quote
VAT (20%)Agency quotes in this table are ex-VAT. If you're not VAT-registered, a £40k quote is £48k out the door.
Stripe UK vs EUPost-Brexit, if you sell to EU consumers you'll likely need a separate Stripe entity or OSS VAT registration. Neither route changes — both need it.
FCA permissionsAnything resembling e-money, payments, lending, insurance mediation, or crypto custody needs FCA authorisation. Software cost is the small number here — legal and audit dwarf it.
How to price your UK SaaS build in 30 minutes
A straight process for deciding between agency, freelance, and DIY — with actual numbers attached.
1
Find your row in the table above
Pick the scope line that matches what you're actually shipping in v1 — not v3. Most founders overscope by two tiers.
2
Add VAT to the agency column
If you're not VAT-registered, multiply by 1.2. That's the real out-the-door number for comparison.
3
Check the FCA / regulated flag
If you're touching payments, lending, e-money or insurance, stop the software pricing exercise. Get a compliance quote first — it will be the bigger number.
4
Decide on delivery mode
Agency if you need a named supplier, procurement cover, or you don't want to touch code. Freelance (£400–£600/day in the UK) if you need flexible capacity. DIY with the boilerplate if you're hands-on and want speed.
5
Estimate your AI spend with the calculator
Marginal Claude Code spend varies by scope complexity and how tight your prompting is. The calculator gives you a GBP range based on the same benchmarks.
Frequently Asked Questions
Why are UK agency quotes lower than US ones for the same SaaS scope?
UK mid-market day rates sit around £650–£900 in London and £500–£750 elsewhere. US equivalents run $1,000–$1,800. The work is comparable; the rate card isn't. Don't assume a US SOW converts 1:1.
Does the £155 boilerplate fee include VAT?
The boilerplate is priced at $199 USD (~£155) and sold as a digital product. Check the checkout for the exact VAT treatment at purchase — it varies by your VAT status.
Can I really ship a multi-tenant SaaS with RBAC for ~£135 of AI spend?
Yes, if you're comfortable in a codebase. The boilerplate already has JWT auth, Drizzle schema, and the modular route pattern — Claude Code plus @backend-dev adds the organisation tenancy, role middleware and invite flow in roughly 6–7 days. It does not replace a senior engineer's judgement on data isolation. Review the migrations before you ship.
What about London vs. Manchester vs. Edinburgh pricing?
Rough deltas from London at the mid-market tier: Manchester / Bristol / Leeds around 20–25% lower, Edinburgh / Glasgow 25–30% lower, Belfast 30–35% lower. Quality varies within each city more than between them — pick the studio, not the postcode.
I'm building FCA-permissioned fintech. Should I still consider DIY?
Not as a primary route. You can prototype with the boilerplate to prove the product, but your production build needs named engineers on an SoW, PI insurance, auditable change management and often SOC 2 Type II. Use the boilerplate for the unregulated parts (marketing site, internal tools) and hire an agency for the regulated core.
Do I need Stripe Connect on day one?
Only if you're paying out to third parties (marketplaces, creator platforms). Standard B2B SaaS uses vanilla Stripe subscriptions — which the boilerplate's Stripe adapter already handles. Connect is a feature module you add later when the marketplace scope arrives.
What does a credible UK freelance developer cost in 2026?
Competent full-stack contractors outside IR35 charge £400–£600/day. Specialists (React Native, real-time, data) push £700+. Cheaper than that usually means junior or offshore-via-middleman — verify directly.
UK SaaS pricing is clearer than it looks — once you separate scope from overhead.
A standard B2B SaaS dashboard in the UK is a £30–£60k agency engagement, or a £155 boilerplate plus ~£80–£150 of Claude Code spend across a week if you're building it yourself. Pick the route that matches how you want to operate, not the one that looks cheaper on paper.
