Planning and permissionsStraight answers

What people ask us about planning and permissions.

Do I need planning permission for my project?

It depends on your property, the proposed work and any planning restrictions in place.

Some schemes qualify as permitted development. We always check eligibility against your actual building before relying on that route.

Next We review your address, planning history and drawings before advising.

Does permitted development apply to flats and maisonettes?

Flats and maisonettes do not get the same permitted development rights as houses.

Prior alterations and existing restrictions also affect what you can do.

Next We confirm the correct consent route for your property type.

What is a lawful development certificate?

A lawful development certificate confirms development is lawful for planning purposes. It differs from building regulations approval.

It must match the exact proposal or existing work precisely.

Next We tell you if a certificate would give useful evidence for your scheme.

Does an Article 4 direction affect my home?

An Article 4 direction can remove specific permitted development rights in its area.

We check the actual direction against your property. We never assume every restriction is the same.

Next We review the council’s planning information for your address.

Can NU guarantee planning approval?

No. We cannot guarantee a council’s decision, and no responsible team can.

Good preparation identifies policy issues and strengthens what we submit. The decision always stays with the council.

Next We agree a plan B if the first application is refused.

Should I get pre-application advice?

Pre-application advice helps when policy, heritage, scale or neighbour impact are uncertain.

Its value depends on the question we ask and the information we supply. It is not planning permission itself.

Next We discuss whether the fee and time are worth it.

How long will planning permission take?

Allow time for surveys, design and validation before the council’s assessment period begins.

Requests for information, consultation and revisions can extend the timeline. Do not treat an indicative decision date as a guaranteed site start.

Next We give you a programme covering preparation, assessment and post-decision tasks.

Can we start as soon as planning permission is granted?

Not necessarily. Read the decision notice carefully for any conditions attached.

Check the other approvals and agreements the works need. Design, technical and contractual readiness are separate questions.

Next We build a pre-start checklist tied to the work you plan.

What happens if planning is refused?

We review the refusal reasons with you before choosing a way forward.

A revision, a new application or an appeal may suit. The right route depends on the refusal and your brief.

Next We compare the cost, benefit and programme impact of each option.

Do trees, ecology or flood risk affect design?

Trees, ecology and flood risk can all be material design constraints.

We identify the relevant surveys, protections and site risks early. That way the design responds to your site, not surprises found after pricing.

Next We tell you which site specific assessments the project needs.

Can I change the approved design later?

Any change must be checked against the approved drawings and conditions first.

We confirm the correct route for the amendment before you build it.

Next We keep a register of proposed changes and their consent status.

Are neighbour objections an automatic refusal?

No. The council assesses every application against relevant planning considerations.

We design to address neighbour impact properly. Support or objection alone does not decide the outcome.

Next We explain the material planning issues raised by any objection.

Could CIL or other planning charges affect my project?

Extra floorspace or new dwellings can attract the Community Infrastructure Levy.

Exemptions may apply, but we check eligibility and procedure before you start. Planning obligations can be a separate cost too.

Next We identify any liability, exemptions and notices you need to submit.
