UK Right to Rent Share Code & Renewal Manager
Right to Rent. Done Right.
Executive Summary
In a nutshell
A landlord-side compliance vault that captures every tenant's right-to-rent share code on move-in, schedules the time-limited follow-up checks before each share-code expiry, and exports a court-ready audit trail. Built for the ~1.6m self-managing UK landlords (and a £25–60/mo letting-agent tier) who currently juggle this in spreadsheets and inboxes — and who face up to £20,000 per occupier in repeat-breach civil penalties under the post-2024 enforcement uplift. The eVisa rollout completed 31 December 2024 has effectively reset the entire scheme onto 90-day rolling share codes — the manual workload just multiplied, and incumbents (Goodlord, Vouch, Lendlord, Landlord Studio) bundle RTR inside £25+/mo all-in suites that DIY landlords don't want to buy.
The Story
Meet the user

Marcus is 42, a delivery operations manager in Birmingham who self-manages two flats — one in Selly Oak, one in Edgbaston. Both currently let to international tenants on time-limited visas. Three months ago he got a polite letter from the Home Office reminding him that the eVisa rollout means there are no more biometric residence permits to photocopy: every check now relies on a 90-day share code, and he has to do a follow-up check before either visa expires or the tenancy hits 12 months, whichever comes first. He has the share codes "somewhere in WhatsApp." He has the screenshots in a folder called *Tenant Stuff 2024*. He thinks one of them — the Selly Oak chap — has a visa that runs out in August. Or maybe September. He's not sure. The letter mentions civil penalties of up to £20,000 per occupier for repeat breaches and "up to five years' imprisonment" for knowing breaches. He spends a Saturday morning trying to build a Google Sheet with conditional formatting. By lunchtime he's given up.
Then a mate in his BTL WhatsApp group drops a link: *£6 a month, takes the share code on move-in, verifies it against the Home Office service in 8 seconds, schedules the follow-up reminder automatically, and gives you a one-click PDF audit pack you can hand to a tribunal*. Marcus signs up that afternoon, plugs in both tenancies, and for the first time in six months his right-to-rent risk lives in one place that emails him before — not after — the next deadline.
Scores
How does this idea stack up?
7.7/10
~1.6m self-managing UK landlords + ~17,000 letting agent branches; combined niche search volume ~12k/month with low competition; no standalone RTR-first product; incumbents bundle it inside £25+/mo all-in suites
Up to £20,000 per occupier for repeat breaches, prison sentences for knowing breaches, "most penalties arise from landlord process failures rather than tenant immigration status" (NRLA quote); CPC of £9.66 on "landlord right to rent check" signals real willingness-to-pay
One API (Home Office Landlord Checking Service / online share code service), one core schedule (90-day eVisa cycles + visa-expiry follow-up), Stripe + Supabase + Next.js — solo-buildable in 3–4 weeks
eVisa rollout completed 31 Dec 2024 reset the scheme onto rolling share codes; February 2024 fine increase to £20k; Renters' Rights Act 1 May 2026 (5 days away) reframes every existing tenancy and creates an "I should sort my compliance" moment
Permanent regulatory obligation — won't disappear, but Goodlord/Lendlord/Landlord Studio will keep improving their bundled RTR over the 2-3 year horizon. 5-year window before "good enough" features appear in incumbent suites
Standard web stack, single Home Office integration, low GTM cost via NRLA / r/uklandlord / landlord WhatsApp networks. <£500 to launch
Strongest
Pain
Landlords are facing real, named, well-publicised £20,000 penalties with rolling 90-day deadlines they cannot mentally track.
Watch out
Durability
This needs an MOAT (audit-trail format, integrations with tenant referencing, deposit-protection register links) to defend against incumbents bolting on a "good enough" RTR module.
Pain Point
The problem
“In practice, most penalties arise from landlord process failures rather than from any problem with the tenant's immigration status. Missing records, checks carried out at the wrong time, or failure to complete follow-up checks are far more common causes of enforcement action.”
— NRLA-cited finding on right-to-rent enforcement
Right to Rent is one of the lowest-knowledge / highest-stakes compliance regimes private landlords face. The 2014 Immigration Act made the initial check mandatory for all adults occupying a rented property in England. The 2016 amendment added criminal penalties — up to five years' imprisonment for "knowing" breaches. The 13 February 2024 enforcement uplift raised maximum civil penalties to **£10,000 per lodger and £20,000 per occupier for repeat breaches** (up from £1,000–£3,000). Then on 31 December 2024 the eVisa rollout completed: physical biometric residence permits were withdrawn and every non-British/Irish tenant moved to a digital status proven by a **90-day share code**. The result: the entire follow-up-check workflow — already widely missed — now runs on a tighter rolling schedule that landlords have no native tooling for.
The pain bites in three places: (1) **Initial check chaos** — tenants email screenshots of expired or wrong-flavour share codes (W- and S-codes are not valid for RTR; only R-codes are), and landlords don't know to reject them. (2) **Follow-up amnesia** — for time-limited tenants, the landlord must check before the visa expires; if missed, the statutory excuse lapses and any subsequent enforcement is uninsurable. The NRLA explicitly notes this is the dominant cause of enforcement action. (3) **Audit-trail gaps** — Home Office guidance requires evidence retained for the duration of the tenancy plus one year. "Folder of screenshots in Drive" does not survive a tribunal-grade challenge.
Self-managing landlords currently cope by setting Google Calendar reminders, taking screenshots, and hoping. Letting agents bolt RTR onto Vouch/Goodlord referencing flows at £5+ per tenant, which is fine at the agency tier but absurdly priced for a single landlord with two tenancies.
