Two products. One mission.
UK paperwork, sorted.

BritStack started with a frustration: most life-admin and business-admin moments in the UK are either hand-crafted by a £500/hour specialist or DIY-ed at midnight on the GOV.UK website hoping you got it right.

We sit in the middle. We build two kinds of products that solve this — one for businesses, one for individuals.

For businesses

AI Voice Agents

A 24/7 AI receptionist that answers your line after hours, captures viewing requests, and routes emergencies to your on-call mobile. Done-for-you setup — your branches, your tone, your booking system.

  • From £499 setup + £299/mo · two tiers (Lite / Pro)
  • Live in 5 working days
  • Cancel anytime, 30 days' notice
  • UK estate & letting agents now · plumbers / clinics next

For individuals

The Toolkit (Shop)

Browser-first apps that walk you through one-off life-admin moments — landlord compliance, self-assessment tax, NHS care appeals, school admissions appeals. Pay once, lifetime updates, your data stays on your device.

  • £49–£89 one-off, no subscription
  • 14-day money back, no questions
  • 100% browser-based, GDPR by design
  • 4 apps · landlord, tax, CHC, school appeals

What we believe

UK-specific, always.

Generic American tools don't know HMRC, the Renters' Rights Act, or the School Admissions Code. We do — because we live here too.

Honest pricing.

No hidden per-minute fees on voice agents. No trial-then-£99/mo subscription on apps. The price you see is what you pay.

Cancel anytime.

Voice agent retainer cancels with 30 days' notice. Toolkit apps refund within 14 days. We earn your repeat business — we don't lock you in.

Honest about limits.

Voice agent isn't a lawyer; the toolkit isn't a chartered accountant. For complex contested cases, we'll point you to free expert helplines (Coram, ACE, Beacon, Citizens Advice, NRLA).
