Homeowners planning an extension, conversion or renovation in 2026 should be aware of a number of changes to England’s planning system.

A new National Planning Policy Framework (NPPF) has been introduced, alongside changes to planning application fees and permitted development rights. While many of the everyday rules for home improvements remain familiar, the changes make it more important than ever to check the planning position before starting a project.

New Planning Framework for 2026

The government published a new National Planning Policy Framework in August 2026, replacing the previous version from December 2024.

The NPPF sets out the government’s planning policies for England and is used by local authorities when preparing local plans and making planning decisions.

For homeowners, the new framework does not mean that extensions, loft conversions or other improvements suddenly have a completely different set of rules. However, it forms part of wider reforms to the planning system and will influence how development is approached across England.

Do Homeowners Still Need Planning Permission?

Whether you need planning permission for an extension or home improvement will continue to depend on the project and property.

Many extensions and alterations can be completed under permitted development rights, meaning a full planning application may not be necessary if the work stays within certain limits.

There are important exceptions. Restrictions can apply to listed buildings, conservation areas and properties where permitted development rights have been removed. Larger extensions may also require prior approval.

Homeowners should also remember that planning permission and Building Regulations are separate. Even if planning permission isn’t required, Building Regulations approval may still be needed.

Planning Application Fees Have Increased

The cost of submitting a planning application in England increased from 1 April 2026 as part of the annual adjustment to planning fees.

For anyone budgeting for an extension or renovation, the application fee is just one potential cost. Architectural drawings, structural calculations, surveys, planning advice and Building Regulations fees may also need to be considered.

Further reforms could also give local authorities greater flexibility over planning fees in the future.

Permitted Development Changes

Changes to permitted development rights are also arriving in October 2026, including new provisions relating to electric vehicle charging.

From 21 October 2026, new rules will make it easier in certain circumstances to install cross-pavement EV charging solutions. These allow a charging cable to run safely through a purpose-built channel across a pavement.

Restrictions will still apply in certain locations, including conservation areas and around listed buildings, so homeowners should check the requirements before installing one.

Planning a Home Improvement in 2026?

The planning system may be changing, but the best advice for homeowners remains simple: check before you build.

Before starting an extension, loft conversion or major renovation, establish whether you need planning permission, whether the work falls under permitted development and what Building Regulations approval may be required.

Checking the rules early can help avoid delays, unexpected costs and problems later in the project.

Planning requirements vary by property, project and location. Always check the requirements that apply to your individual project.
