1. Do You Actually Need Planning Permission?

Not all projects require full permission.

You may not need planning if your project falls under Permitted Development rights (common for some rear extensions and loft conversions).

However, you will usually need planning if:

  • You’re in a Conservation Area

  • The property is Listed

  • It’s a large extension or significant alteration

  • It’s a new dwelling

  • Your PD rights have been removed

In 2026, many councils are stricter on design quality and neighbour impact, so even where PD applies, a Lawful Development Certificate is strongly recommended.


2. Pre-Application Advice (Often Worth It)

Most local authorities now offer formal pre-app advice via the Planning Portal or directly through the council.

Benefits:

  • Early feedback from a planning officer

  • Reduced refusal risk

  • Clarity on design expectations

For larger schemes or sensitive sites, this step can save months.


3. Prepare the Right Drawings & Documents

A strong planning application in 2026 typically includes:

  • Existing & proposed floor plans

  • Existing & proposed elevations

  • Site location plan

  • Block plan

  • Design & Access Statement (where required)

  • Heritage Statement (if applicable)

  • Supporting technical reports (ecology, flood risk etc. if triggered)

The key shift in recent years is design quality expectations. Councils are increasingly assessing:

  • Scale and massing

  • Materials

  • Impact on street scene

  • Neighbour amenity

Poor-quality or vague drawings lead to delays and objections.


4. Submit via the Planning Portal

Most applications are submitted online through the UK government’s Planning Portal system.

The application is validated by the local authority and then enters the statutory consultation period.

Typical timeframes:

  • Householder application: ~8 weeks

  • Minor development: 8–13 weeks

  • Larger schemes: 13+ weeks

Delays often occur due to:

  • Validation issues

  • Missing information

  • Officer workload


5. Public Consultation & Neighbour Comments

Neighbours are notified and can comment.

In 2026, objections commonly relate to:

  • Overlooking

  • Overshadowing

  • Scale

  • Parking

Good design and clear drawings significantly reduce resistance.


6. Decision

You’ll receive either:

  • Approval (possibly with conditions)

  • Refusal

If refused, you can:

  • Amend and resubmit

  • Appeal

However, most refusals stem from design issues that could have been resolved earlier.


7. Planning Permission ≠ Building Regulations

Planning deals with appearance and impact.

You will still need:

  • Building Regulations approval

  • Structural design

  • Detailed construction drawings

Many homeowners underestimate this step. Planning is only the first approval.


What’s Changed in 2026?

While national legislation evolves gradually, key trends include:

  • Greater emphasis on sustainability and energy efficiency

  • Increased scrutiny in rural and conservation locations

  • Faster digital validation systems

  • Stronger enforcement where development breaches occur

Local knowledge now matters more than ever.


How Long Does the Whole Process Take?

Realistically:

  • Design & preparation: 3–6 weeks

  • Determination period: 8–10 weeks

  • Building Regulations preparation: 4–8 weeks

Total: 3–5 months before construction can begin in most cases.


Final Advice

Planning success is rarely about “just submitting drawings.” It’s about:

  • Understanding local policy

  • Designing appropriately for the setting

  • Anticipating objections

  • Submitting correctly the first time

If you’re considering an extension, loft conversion or new build in North Yorkshire, County Durham, Teesside or surrounding areas, early advice makes a measurable difference.
