Section 21 Is Gone, MTD Is Live: What August 2026's Rule Changes Mean for UK Landlords

Two major rule changes have landed for UK landlords this year — the Renters' Rights Act's abolition of Section 21 evictions and the first Making Tax Digital filing deadline. Here's what's changed, and why most professional investors aren't slowing down.

Let me ask you: if you'd read the property headlines from this year in isolation — no-fault evictions banned, rent increases restricted, quarterly tax filing now mandatory — would you guess that 84% of professional landlords are planning to grow their portfolios over the next year?

It sounds counterintuitive. But that's exactly where the data sits right now, and it says a lot about the difference between reacting to regulatory noise and understanding what it actually means for your strategy.

The Renters' Rights Act has teeth now

The headline change: Section 21 "no-fault" evictions ended on 1 May 2026. Landlords can no longer end a tenancy simply because they choose to — every eviction now has to go through Section 8, backed by one of the statutory grounds (rent arrears, sale of the property, moving in a family member, and so on). Section 21 notices served before 1 May can still be used to apply to court, but only up until 31 July 2026, so that transition window has now closed too.

Rent increases have changed as well. From 1 May, landlords must serve a formal Section 13 notice to raise rent, and it can only happen once per tenancy period. Tenants who think an increase is above market rate can challenge it — for a £47 fee — through the First-tier Tribunal. On top of that, all assured tenancies are now periodic ("rolling") agreements rather than fixed terms, tenants need only give two months' notice to leave, and existing tenants must have received the government's official information sheet by 31 May 2026 or landlords risk penalties starting at £7,000 for a first offence and rising to £40,000 for repeat non-compliance. A Private Rented Sector database — where landlords register themselves and their properties — is due to roll out by region later this year, followed by a mandatory Ombudsman scheme in 2028.

None of this is small print. It's a genuine shift in how tenancies are managed day to day, and it rewards landlords who treat compliance as a system rather than an afterthought — proper documentation, clear grounds for any possession claim, and rent reviews done by the book.

Making Tax Digital has its first real deadline

Alongside the tenancy changes, the tax side of the ledger has shifted too. Landlords with qualifying gross income over £50,000 have been required to use Making Tax Digital for Income Tax since 6 April 2026, and 7 August 2026 marks the deadline for their first quarterly update — a digital summary of income and expenses for the 6 April to 5 July period, filed through MTD-compatible software rather than a traditional Self Assessment return. The threshold drops to £30,000 from April 2027 and £20,000 from April 2028, so this is a widening net, not a one-off adjustment. The annual End of Period Statement and Final Declaration still follow by the usual 31 January deadline — the quarterly update is an added layer of reporting discipline, not a replacement for it.

So why are professional investors still buying?

Here's the part that tends to surprise people. Handelsbanken's 2026 Property Investor Report, surveying 200 UK property professionals, found that only 1% plan to exit the market entirely this year — while 84% intend to grow their portfolios over the next 12 months, up sharply from 54% the year before. Nearly all respondents (93%) expect their portfolio values to rise. Asked why they're buying, 70% pointed to attractive valuations and buying opportunities, 58% cited continued strong rental demand, and 33% named improving access to financing.

That's not investors ignoring the regulatory changes — it's investors who've priced them in. Every cycle of tighter compliance tends to push out landlords who were managing property as a side hustle, which typically means less amateur competition and steadier, more professionally-run stock for everyone else. For hands-free investors in particular, this is precisely the kind of environment where having proper systems already in place — legal safeguarding, vetted lettings management, KYC/AML compliance built in from day one — stops being a nice-to-have and starts being the difference between a smooth year and a stressful one.

What this means for your next move

If you're holding property, now is a sensible moment to check your paperwork is airtight: correct notices, up-to-date compliance records, and a plan for the MTD deadlines heading your way. If you're weighing a first purchase, the fundamentals professional investors are pointing to — valuations, rental demand, financing access — haven't gone anywhere; the rules around how you manage the asset have simply matured.
