Property law in England is undergoing a concentrated period of change. Several reforms that were debated or consulted on in previous years have now taken effect, while others remain at the proposal stage. Understanding which rules are already binding, which are imminent and which are still under consultation is the first practical step for anyone buying, selling, developing or letting property in 2026.
Building safety regime: what the new levy and updated standards require
Most competitor guides group building safety under a single heading tied to the Grenfell aftermath. The operational detail that matters now is more granular, because two specific measures landed in autumn 2026.

An updated Approved Document B took effect on 30 September 2026. It introduced provisions concerning evacuation lifts and staircases in taller residential blocks, tightening the technical standards that developers must meet at design stage. The day after, on 1 October 2026, the Building Safety Levy began applying to many new residential developments, subject to exceptions.
The levy is a funding mechanism. Its purpose is to make developers contribute towards the cost of remediating unsafe cladding in existing buildings. For anyone costing a new scheme, this changes the financial model: the levy sits alongside construction costs and must be factored into viability assessments before a project breaks ground.

Separately, the government has proposed a new statutory route to address unsafe cladding not only in taller buildings but in medium-rise residential buildings as well. These are proposed measures rather than reforms already in force, so their final shape may shift after consultation. The direction of travel, though, is clear: liability for defective building work continues to widen.
Nature Restoration Levy: how planning obligations are shifting for developers
Environmental mitigation has traditionally been handled project by project. A developer assesses the ecological impact of a specific site, agrees mitigation measures, and delivers them (or pays for them) before or during construction. That model is being supplemented by something structurally different.
Under the framework established by the Planning and Infrastructure Act 2025, developers may be able to use Environmental Delivery Plans and pay a Nature Restoration Levy for specified environmental impacts. The idea is strategic rather than piecemeal: instead of each site producing its own bespoke ecological offset, a centrally managed fund directs money towards restoration at landscape scale.
What this means in practice:
- Developers working on sites covered by an Environmental Delivery Plan could discharge certain nature-related obligations by paying the levy, rather than commissioning individual ecological surveys and on-site mitigation for every protected species or habitat.
- The levy amount will relate to the type and scale of environmental impact, so costs will vary between projects. Developers need to check whether their site falls within an active Environmental Delivery Plan area.
- Strategic restoration funded by the levy is intended to deliver better ecological outcomes than fragmented, site-level measures.
This reform applies to England. Scotland, Wales and Northern Ireland each have their own environmental planning frameworks, so cross-border developers cannot assume the same rules apply everywhere.
Renters’ Rights Act: what changed for landlords and tenants in England
The Renters’ Rights Act has already altered the private rented sector in England, and its effects are now visible in how tenancies operate day to day.
The most significant change is the abolition of Section 21 “no-fault” evictions. Landlords can no longer end an assured shorthold tenancy simply by giving two months’ notice without stating a reason. Possession now requires a specific ground, such as the landlord intending to sell the property or move into it.
For tenants, this means greater security of tenure. For landlords, it means tighter procedural requirements when seeking possession. A landlord who fails to use the correct ground, or who cannot evidence the stated reason, faces a longer and more uncertain legal process.
The Act also introduced measures affecting rent increases. Landlords must follow a prescribed mechanism for raising rent, and tenants can challenge increases they consider excessive through the First-tier Tribunal. The practical result is that rent-setting in the private sector now operates within a more regulated framework than at any point in the past three decades.
Practical impact on portfolio landlords
Landlords holding multiple properties face a compliance burden that scales with portfolio size. Each tenancy must be managed under the new rules, and the cost of a single procedural error (a failed possession claim, a disputed rent increase) can run to several months of lost income plus legal fees. Professional letting agents have had to retrain staff and update template documents to reflect the reformed grounds for possession.
Home buying and selling reform: the government consultation roadmap
A separate reform track targets the transaction process itself. The government’s consultation on home buying and selling reform sets out a roadmap to reduce the time between an accepted offer and completion.
The roadmap identifies several causes of delays and failed transactions:
- Upfront information is often missing, late or inconsistent, so problems surface only after significant time and money have been spent.
- The role of property agents is not defined by clear professional standards, leading to varying practices in how transactions are managed.
- There is no unified digital infrastructure for sharing property data between parties, which forces professionals to chase updates manually.
The proposed reforms include mandatory upfront property information packs and clearer regulatory expectations for estate agents. These are consultation-stage proposals. They are not yet law, and their final form will depend on industry responses and parliamentary time. But the direction suggests that the conveyancing process will become more front-loaded, with sellers expected to gather and disclose key information before marketing a property rather than after a buyer has committed.
Commercial lease reform: upwards-only rent review proposals
In the commercial sector, the government has proposed a prohibition on upwards-only rent reviews in new commercial leases. Under the current convention, many commercial leases include a clause ensuring that rent can only be adjusted upward at review, never downward, regardless of market conditions.
A ban would mean that new leases must permit rent to move in either direction at review, reflecting actual market value at the time. For tenants, this reduces the risk of being locked into above-market rents during a downturn. For landlords and their lenders, it introduces income uncertainty that could affect property valuations and loan covenants.
This reform remains at the proposal and consultation stage. It would apply only to new leases, not to existing agreements. Landlords negotiating long-term lettings in 2026 should consider how a future ban might interact with lease terms agreed now, particularly where a lease is due for renewal after the reform takes effect.
The breadth of change across residential, commercial and environmental law makes 2026 a year where assumptions built on older rules carry real financial risk. Each reform described above applies primarily to England, and timelines differ between enacted law, commenced provisions and open consultations. Checking which category a rule falls into, before acting on it, remains the single most useful habit for anyone operating in this market.
