to Building Regulations vs Planning Permission

The Homeowner's Guide to Building Regulations vs Planning Permission

Planning a renovation or extension can quickly become confusing when terms such as Planning Permission, Permitted Development and Building Regulations start appearing in conversations.

Although they are often mentioned together, they are two separate requirements that deal with different aspects of your project. In many cases, a project may need both.

At Summit Haus, we regularly work with homeowners across Hampshire, Berkshire and Surrey, helping coordinate the construction process and professional project management from the early stages through to completion.

Planning Permission — "Can I build it?"

Planning Permission is primarily concerned with whether a proposed development is acceptable in its location.

It considers things such as:

• The size and appearance of a proposed extension

• How the development affects neighbours

• The use of the property or land

• The surrounding area

• Local planning policies

• Special restrictions such as conservation areas
  

Some home improvements may fall under Permitted Development, meaning a planning application may not be required, provided the relevant conditions and limitations are met.

If you're unsure whether your project requires planning permission, it is important to check before starting work.

Building Regulations — "How must it be built?"

Building Regulations are concerned with the technical standards that construction work must meet.

They cover areas including:

• Structural safety

• Fire safety

• Insulation and energy efficiency

• Ventilation

• Drainage

• Electrical safety

• Accessibility
  

Building Regulations approval is separate from Planning Permission, and many extensions, alterations and renovations will require building control involvement even when planning permission isn't needed.

Do I Need Both?

Possibly.

For example, a new extension could require:

Planning Permission→ Is the proposed development acceptable?

Building Regulations→ Will the extension be constructed to the required standards?

These are separate processes, so receiving planning permission does not automatically mean that the work has Building Regulations approval.

A Simple Way to Remember It

Planning Permission	Building Regulations
Can I build it?	How must it be built?
Looks at the development	Looks at construction standards
Considers the wider area	Considers safety and performance
Local planning authority	Building control body

What About Permitted Development?

Permitted Development rights allow certain types of home improvement and extension to be carried out without a planning application, subject to specific conditions and limitations.

However, Permitted Development does not mean Building Regulations can be ignored. The two systems remain separate.

This is one of the most common areas of confusion for homeowners.

Where Does Your Builder Fit In?

A good contractor should be able to help you understand what needs to be considered before construction begins.

At Summit Haus, our role goes beyond simply carrying out the building work. Through careful project management, we help coordinate the various elements of a renovation or extension, working alongside architects, structural engineers, building control and other professionals where required.

For homeowners, particularly families continuing to live in their property during the works, good planning and a family friendly approach can make a significant difference to the overall experience.

Before Starting Your Project

Before construction begins, make sure you understand:

• Whether Planning Permission is required

• Whether your project falls under Permitted Development

• What Building Regulations requirements apply

• Who is responsible for the relevant applications

• How inspections and certification will be handled

The exact requirements depend on the property and proposed works, so it is important to obtain project-specific advice rather than relying solely on general guidance.

Final Thoughts

Planning Permission and Building Regulations serve different purposes, but both can be important parts of a successful renovation or extension.

Understanding the difference early can help you plan your budget, programme and design with greater confidence.
