What you need to know
Embarking on a building project can feel like a maze of regulations and paperwork, especially when terms like "planning permission" and "building regulations" come into play. While they are often mentioned together, these two requirements serve very different purposes. Here’s a straightforward guide to help you understand what they mean, when you need them, and how Harrington Builders can help.
What is planning permission?
Planning permission is all about ensuring that your building project fits within the broader development plan of your local area. It’s focused on the external appearance and impact of your project. The local planning authority (LPA) assesses your proposal to ensure it complies with guidelines on things like:
- Does the project align aesthetically with the style of the area?
- Will it obstruct views, reduce privacy, or cause disruptions to neighbours?
- Does it respect protected areas or greenbelt land?
When Do You Need Planning Permission?
Planning permission may be required for:
- Building a new property
- Large extensions or loft conversions
- Major external alterations (e.g., changing the roof height)
- Converting a property into flats
Harrington Insight: Some projects can fall within permitted development rights, meaning a separate planning application may not be required, but conditions and limits apply. An architect or planning adviser can confirm the position for your property and proposal; Harrington Builders can coordinate with the appointed professionals as the project develops.
What are Building Regulations?
Building regulations are different as they focus on the safety, functionality, and sustainability of the structure itself. These rules ensure that the building is constructed to a high standard and is safe to use. Key areas covered include:
- Foundations, beams, and load-bearing walls for structural stability
- Escape routes, fire doors, and alarms.
- Insulation, heating systems, and ventilation.
- Ensuring spaces are usable for all individuals.
When Do You Need Building Regulations Approval?
Many construction and alteration projects are covered by Building Regulations even when planning permission is not required, although exemptions and competent-person schemes can apply. This includes:
- Extensions and loft conversions
- Internal alterations (e.g removing a wall)
- Installing new plumbing or electrics
- Window replacements
Harrington Insight: Permitted development and Building Regulations are separate systems. Building Regulations requirements may still apply even where planning permission is not needed, so the position should be checked for the specific work with the relevant professional or building control body.
How Harrington Builders can help coordinate the process
We can discuss the information already available for your project and work alongside your appointed architect, structural engineer, planning adviser and Building Control team where required. Formal design, structural calculations and planning advice should be provided by the appropriately qualified or appointed professional.
During construction, we work to the approved project information and coordinate the building work carefully with the relevant inspections and technical requirements.
See our Design & Build coordination and Structural Alterations services, or get in touch to discuss your project and the stage it has reached.
