Experiencing the Following Challenges? Engena Can Help.

Purple Stop Sign Icon - Hexagon with Exclamation mark

Capital at Risk from Planning Refusal

A planning refusal doesn't just delay your project, it puts already-invested capital, land options, and grid connection deposits at risk. Appeals are your route to recovery, but they require specialist expertise.

Complex Appeal Procedures

Choosing the wrong appeal route (written reps vs. hearing vs. inquiry), missing procedural deadlines, or submitting weak evidence leads to wasted costs and upheld refusals.

Technical Evidence Requirements

Appeals require robust technical evidence - updated assessments, policy analysis, and expert witness testimony. Planning Inspectors have no tolerance for gaps, contradictions, or speculation.

Purple Date and Time Icon

Lost Time & Investor Confidence

Appeals add 6-18 months to project timelines. Without clear strategy and experienced management, investor confidence evaporates and projects fail before the appeal is even heard.

We specialise in renewable energy planning appeals; managing the entire process from grounds of appeal through to inquiry advocacy, with a proven track record of overturning refusals across England, Scotland and Wales.

We prepare comprehensive grounds of appeal, manage all procedural submissions (statements of case, proofs of evidence, rebuttal evidence), and coordinate with the Planning Inspectorate to ensure compliance with timetables.

We update and strengthen technical assessments as needed (landscape, ecology, noise, etc.), instruct expert witnesses, and coordinate evidence to address the specific reasons for refusal effectively.

We prepare robust planning policy arguments supported by relevant case law, demonstrating how your project complies with development plan policies and aligns with national planning policy (NPPF, NPS).

For public inquiries and hearings, we represent you throughout, cross-examining Council witnesses, presenting expert evidence, and delivering closing submissions that frame the case for the Inspector.

If successful, we coordinate discharge of conditions with the LPA. If unsuccessful, we advise on potential legal challenge or alternative strategies.

FAQs

National statistics show approximately 30-40% of planning appeals are allowed. Our success rate for renewable energy appeals is 70%+, reflecting our specialist expertise and case selection.

6-9 months for written representations, 9-12 months for hearings, 12-18 months for public inquiries. Government targets are shorter, but real-world timelines are typically longer due to Inspector availability and procedural delays.

Sometimes. If the refusal is due to fixable design issues (e.g., turbine height, panel layout), scheme amendments can strengthen your case. We'll advise during our refusal analysis whether redesign is strategically beneficial.

It varies by complexity and appeal route. Written reps: £20k+. Hearings: £40k+. Public inquiries: £80k+. This includes professional fees, expert witnesses, and updated technical assessments. We'll provide a fixed-fee quote after reviewing your refusal.

You have limited options for legal challenge (High Court judicial review) if you believe the Inspector erred in law. Alternatively, we can advise on scheme redesign and resubmission strategies. Some schemes benefit from waiting for policy changes.

Yes, though it depends on what stage you're at. If deadlines have been missed or weak evidence submitted, recovery is harder. We'll conduct an urgent review and advise on the best path forward.

Our fees are fixed and not contingent on outcome, we can't ethically operate on a "no win, no fee" basis for planning appeals. However, we're selective about cases we take on and will be honest during initial review if we believe appeal prospects are weak.
