TenancyFit
Section 21 is abolished on 1 May. TenancyFit walks every UK landlord through the Renters' Rights Act changes, generates compliant new tenancy agreements, and builds a personalised action plan with 30 days left.
The Idea
The Renters' Rights Act 2025 takes full effect on 1 May 2026. Three things change immediately. Section 21 no-fault evictions are abolished, every existing tenancy automatically converts to a periodic (rolling) tenancy, and every landlord in England must send their tenants the government's Renters' Rights Act Information Sheet by 31 May 2026 or face a fine of up to £7,000. The NRLA estimates 2.3 million private landlords are affected. Most are not ready. TenancyFit is a compliance tool for this transition: it takes a landlord's situation (properties owned, tenancy types, current agreement templates), explains exactly what changes apply to them, generates a compliant post-May 1 tenancy agreement template for new lets, and produces a personalised 5-step action plan they can work through this week.
Why Now
30 days. The May 1 date is fixed and legally significant. Section 21 notices can only be served until April 30. After that, the only route to possession is through the 18 new Schedule 1 grounds under the Act, using new Section 8 notice forms. The old Assured Shorthold Tenancy framework is dead for new lets from May 1. The awareness gap is substantial: a Property118 survey from February 2026 found 38% of self-managing landlords had not reviewed their tenancy agreements or Section 21 procedures ahead of the deadline. The NRLA has been running awareness campaigns since January; Rightmove published a five-part landlord guide series in March. Demand is building but the supply of plain-English, actionable compliance tools for non-expert landlords is thin. Estate agents are offering compliance reviews at £150-300 per property. Solicitors charge £400 per hour. The self-serve gap is wide open.
How to Build
An intake form: property count, current tenancy types (fixed-term AST or already periodic), any tenancies up for renewal before May 1, and whether they self-manage or use an agent. Claude then generates a personalised compliance summary covering what changes apply to them, what they must do before May 1, what they must do by May 31, and what the new rules mean for future lets. The core output is a new tenancy agreement template generator. Post-May 1 agreements cannot use the old fixed-term AST model. Claude generates a clean, compliant template using the Act's required periodic structure, the correct rent review language (must reference the new Chapter 1 statutory process), and updated pet request provisions. A Section 8 possession guide maps the 18 new Schedule 1 grounds to plain-English descriptions, so landlords understand which grounds apply to their situation and what evidence is needed. Output: a PDF pack with the action plan, new tenancy template, and possession ground reference card. Stack: Next.js, Vercel, Stripe, Claude API.
Revenue Model
£29 per landlord for the compliance pack: personalised action plan, new tenancy agreement template, and Section 8 possession guide. £79 per year for the Pro subscription: unlimited tenancy template generation across multiple properties, monthly compliance updates as secondary legislation is confirmed, a document vault for tracking which tenants have received their Information Sheets, and a rent review reminder service when the new statutory process applies. The price anchors against estate agent compliance reviews at £150-300 per property and solicitor consultations at £400 per hour. For any landlord with two or three properties, £29 is a trivial purchase. Target 3,000 landlords in April and May at the £29 rate: £87,000 in the urgency window. NRLA community, Property118, and Landlord Zone are the distribution channels: post free plain-English content on the three most confusing changes, link to the paid pack.
Effort
1 week to v1. Day 1-2: the intake form and Claude prompt chain that generates the personalised compliance summary. Test against five scenarios: single flat, HMO, multiple properties with staggered renewals, fixed-term ending before May 1, and Section 21 notice already served. Day 3-4: the new tenancy agreement template generator, reviewed against the Act's requirements. This is research work: read the Act itself, the GOV.UK guidance, and the NRLA's solicitor-reviewed template framework. Day 5: PDF pack output and the Section 8 possession guide. Day 6: Stripe checkout and landing page with the 30-day urgency framing. Day 7: distribution. Join five landlord Facebook groups and Property118. Post a free plain-English guide to the three most confusing changes. Include the product link.
Risk
Three risks. First, the legal disclaimer: the tenancy template and possession guide are not legal advice and must carry that disclaimer prominently. Frame TenancyFit as a starting point that reduces solicitor time rather than replacing it. Second, accuracy: if the tenancy template contains a non-compliant clause, a landlord could face serious consequences. Every template must be reviewed by a qualified solicitor before shipping. Budget one review session (around £300) before launch. Third, shelf-life: once landlords have updated their templates and understood the new rules, the immediate need is resolved. The £79 subscription tier with ongoing compliance updates and document tracking is what turns this into a durable business rather than a one-month sprint.
How to Market It
The deadline does the marketing for you, but you still need distribution. Start with Property118 and Landlord Zone: post a free plain-English guide to the three most confusing Renters' Rights Act changes and link to TenancyFit in the bio. These are the forums landlords actually use when they get a legal letter they don't understand. Second, Reddit: r/LandlordUK and r/HousingUK. Post as a helpful resource, not a pitch. Third, NRLA: they are actively emailing 100,000 members about these changes. A well-timed outreach email offering TenancyFit as a member resource, even at a discount, could drive hundreds of signups in a week. Fourth, LinkedIn: search "landlord" or "property investor" and post one piece of content per day for the first two weeks, each covering one specific change in plain English. Let the compliance anxiety bring people to you. Fifth, Google: "section 21 abolished 2026", "renters rights act tenancy template", and "guaranteed rent review 2026" will all spike in April and May. A single well-optimised landing page targeting those queries costs nothing and compounds. Budget roughly four hours per week on community posting and LinkedIn, zero on paid ads in the first month.
The urgency is extraordinary. 2.3 million private landlords, a £7,000 fine for missing the Information Sheet deadline, and the end of Section 21 for the first time since 1988 create conditions for fast adoption. The pricing is a rounding error against the alternatives. The awareness gap is documented and large. The one real risk is template accuracy, which a pre-launch solicitor review addresses for around £300. This is a strong, fast urgency play with a clear subscription path beyond the launch window. Build this.
