Planning Appeals for London Home Renovations: Process, Success Rates, and Strategy Guide

NOT ALL PLANNING REFUSALS SHOULD BE APPEALED. THE FIRST STEP IS TO OBJECTIVELY ASSESS WHETHER THE LPA'S REASONS FOR REFUSAL HAVE MERIT AND WHETHER AN APPEAL INSPECTOR IS LIKELY TO TAKE A DIFFERENT VIEW.

STRONG GROUNDS FOR APPEAL: THE DECISION WAS INCONSISTENT WITH THE DEVELOPMENT PLAN — THE PLANNING OFFICER REFUSED A SCHEME THAT COMPLIES WITH THE LOCAL DEVELOPMENT FRAMEWORK (LDF), NATIONAL PLANNING POLICY FRAMEWORK (NPPF), AND SUPPLEMENTARY PLANNING DOCUMENTS (SPDS) BUT CITED POLICY REASONS THAT DON'T HOLD WATER. THE DECISION DEPARTED FROM PERMITTED SCHEMES ON COMPARABLE PROPERTIES NEARBY — A REFUSAL FOR AN EXTENSION THAT IS VERY SIMILAR IN SCALE, DESIGN, AND IMPACT TO PREVIOUSLY APPROVED SCHEMES ON THE SAME STREET IS A STRONG ARGUMENT FOR APPEAL. NEIGHBOUR OBJECTIONS DROVE THE DECISION WITHOUT MATERIAL PLANNING GROUNDS — A REFUSAL DRIVEN BY NEIGHBOUR OBJECTIONS BASED ON PERCEIVED LOSS OF VALUE, PERSONAL PREFERENCE, OR NON-MATERIAL PLANNING ISSUES IS A CANDIDATE FOR APPEAL (LOSS OF VALUE AND GENERAL NEIGHBOUR OPPOSITION ARE NOT MATERIAL PLANNING CONSIDERATIONS). A SINGLE REASON FOR REFUSAL THAT CAN BE SPECIFICALLY ADDRESSED — IF THE REFUSAL IS ON ONE CLEAR GROUND (E.G., INSUFFICIENT LANDSCAPING), IT MAY BE ADDRESSABLE BY ADDITIONAL INFORMATION IN AN APPEAL.

WEAK GROUNDS FOR APPEAL: THE DESIGN IS GENUINELY INAPPROPRIATE IN CHARACTER — IF THE INSPECTOR AND LPA ARE LIKELY TO AGREE THAT THE DESIGN IS HARMFUL TO THE CHARACTER OF THE CONSERVATION AREA OR STREET, APPEAL SUCCESS IS UNLIKELY. MULTIPLE CLEAR POLICY BREACHES — WHERE THE PROPOSAL CLEARLY BREACHES SEVERAL PLANNING POLICIES AND THE LPA'S DECISION IS WELL-REASONED, THE EFFORT AND COST OF APPEAL MAY NOT BE JUSTIFIED. THE ALTERNATIVE IS USUALLY REDESIGN AND RESUBMISSION (FREE FOR HOUSEHOLDER APPLICATIONS WITHIN 12 MONTHS OF THE ORIGINAL DECISION).

FOR HOUSEHOLDER PLANNING APPEALS (THE TYPE OF APPEAL RELEVANT TO LONDON HOME EXTENSIONS AND RENOVATIONS), THREE APPEAL PROCEDURES ARE AVAILABLE.

WRITTEN REPRESENTATIONS (THE MOST COMMON FOR HOUSEHOLDER APPEALS): THE MOST COMMON APPEAL PROCEDURE FOR HOUSEHOLDER PLANNING APPEALS — ALL PARTIES (APPELLANT, LPA, INTERESTED PARTIES) SUBMIT WRITTEN STATEMENTS AND THE INSPECTOR DETERMINES THE APPEAL BY READING THE WRITTEN EVIDENCE AND VISITING THE SITE. NO HEARING OR ORAL PRESENTATIONS. TYPICAL TIMESCALE: 14 TO 20 WEEKS FROM START OF APPEAL TO DECISION (PIMS — PLANNING INSPECTORATE MANAGEMENT SYSTEM — TRACKS CASE PROGRESS). SUCCESS RATE FOR HOUSEHOLDER WRITTEN REPRESENTATION APPEALS: APPROXIMATELY 33% NATIONALLY; LONDON BOROUGHS VARY (SOME HAVE HIGHER REFUSAL RATES AND THEREFORE HIGHER APPEAL RATES).

HEARING (SUITABLE FOR MORE COMPLEX CASES): A SEMI-FORMAL DISCUSSION LED BY AN INSPECTOR AT A SET HEARING DATE. APPROPRIATE WHERE THERE ARE COMPLEX POLICY OR TECHNICAL ISSUES THAT BENEFIT FROM DISCUSSION RATHER THAN WRITTEN EXCHANGE ONLY. LESS FORMAL THAN AN INQUIRY — WITNESSES ARE NOT CROSS-EXAMINED. TYPICAL TIMESCALE: 24 TO 32 WEEKS.

INQUIRY (FORMAL, FOR MAJOR OR COMPLEX APPEALS): A FORMAL COURT-LIKE PROCEDURE WITH LEGAL ADVOCATES, EXPERT WITNESSES, AND CROSS-EXAMINATION. RARELY USED FOR SIMPLE HOUSEHOLDER EXTENSIONS — TYPICALLY RESERVED FOR LARGE DEVELOPMENT APPEALS OR WHERE LEGAL ARGUMENTS NEED VENTILATION. COSTS ARE SIGNIFICANTLY HIGHER.

FAST-TRACK APPEAL (HOUSEHOLDER APPEALS UNDER 6 WEEKS): THE PLANNING INSPECTORATE HAS INTRODUCED A FAST-TRACK APPEAL PROCEDURE SPECIFICALLY FOR HOUSEHOLDER APPEALS. ELIGIBLE CASES ARE DETERMINED BY WRITTEN REPRESENTATIONS WITHIN APPROXIMATELY 6 WEEKS. THE FAST-TRACK PROCEDURE IS ONLY AVAILABLE WHERE THE LPA SUPPORTS THE FAST-TRACK APPROACH.

PLANNING APPEALS IN ENGLAND ARE SUBMITTED ONLINE TO THE PLANNING INSPECTORATE (PINS) VIA THE APPEAL A PLANNING DECISION SERVICE ON GOV.UK (HTTPS://WWW.GOV.UK/APPEAL-PLANNING-DECISION).

APPEAL DEADLINE: THE APPEAL MUST BE SUBMITTED WITHIN 12 WEEKS OF THE DATE OF THE LPA'S DECISION NOTICE. MISSING THIS DEADLINE IS FATAL TO THE APPEAL — THERE IS NO EXTENSION. START THE APPEAL PROCESS AS SOON AS A REFUSAL IS RECEIVED.

APPEAL FORM AND DOCUMENTS: THE ONLINE APPEAL FORM (COMMONLY CALLED THE APP FORM OR PLANNING APPEAL FORM) REQUIRES: PROPERTY ADDRESS AND DESCRIPTION OF THE DEVELOPMENT. LPA CASE NUMBER AND DECISION REFERENCE. GROUNDS OF APPEAL (THE REASONS WHY THE DECISION WAS WRONG). APPEAL STATEMENT (A DETAILED WRITTEN ARGUMENT SUPPORTING THE APPEAL). COPIES OF ALL PLANNING APPLICATION DOCUMENTS (DRAWINGS, PLANS, SUPPORTING DOCUMENTS). A COPY OF THE DECISION NOTICE (THE LPA'S REFUSAL LETTER). IF A SITE VISIT IS REQUIRED (USUALLY YES FOR HOUSEHOLDER APPEALS), THE APPELLANT MUST MAKE THE PROPERTY AVAILABLE TO THE INSPECTOR.

GROUNDS OF APPEAL CONTENT: THE APPEAL STATEMENT SHOULD SPECIFICALLY ADDRESS EACH REASON FOR REFUSAL IN THE LPA'S DECISION NOTICE, CITING: THE RELEVANT NATIONAL PLANNING POLICY FRAMEWORK (NPPF) PARAGRAPHS THAT SUPPORT THE SCHEME. THE RELEVANT LOCAL PLAN POLICIES AND HOW THE SCHEME COMPLIES. COMPARATOR DECISIONS — APPEAL DECISIONS AND PLANNING PERMISSIONS ON COMPARABLE PROPERTIES IN THE SAME AREA THAT SUPPORT THE APPELLANT'S CASE. CASE LAW IF RELEVANT (THOUGH LESS COMMON IN SIMPLE HOUSEHOLDER APPEALS). THE PLANNING INSPECTORATE PUBLISHES ALL APPEAL DECISIONS — SEARCHING PINS APPEAL DECISIONS FOR COMPARABLE CASES IN THE SAME LONDON BOROUGH IS ESSENTIAL RESEARCH FOR PREPARING A STRONG APPEAL STATEMENT.

SUCCESS RATES: NATIONALLY, APPROXIMATELY 30 TO 35% OF HOUSEHOLDER PLANNING APPEALS ARE ALLOWED. IN LONDON, BOROUGH-BY-BOROUGH RATES VARY — BOROUGHS WITH TIGHTER DESIGN GUIDANCE (ROYAL BOROUGH OF KENSINGTON AND CHELSEA, CAMDEN) TEND TO HAVE LOWER APPEAL SUCCESS RATES FOR CONSERVATION AREA SCHEMES. BOROUGHS WITH LESS ESTABLISHED CONSERVATION AREA POLICIES TEND TO HAVE HIGHER APPEAL ALLOWANCE RATES.

COSTS OF A PLANNING APPEAL:

APPEAL FEE: THERE IS NO FEE FOR SUBMITTING A PLANNING APPEAL TO THE PLANNING INSPECTORATE — APPEALS ARE FREE. THIS IS AN IMPORTANT POINT OFTEN MISUNDERSTOOD BY CLIENTS.

PLANNING CONSULTANT OR SOLICITOR FEE FOR APPEAL STATEMENT PREPARATION: A PLANNING CONSULTANT PREPARING THE APPEAL STATEMENT AND MANAGING THE APPEAL PROCESS WILL TYPICALLY CHARGE £1,500 TO £4,000 FOR A HOUSEHOLDER APPEAL WRITTEN REPRESENTATIONS CASE. ARCHITECTURAL DRAWINGS OR ADDITIONAL SURVEYS TO SUPPORT THE APPEAL: £500 TO £2,000 DEPENDING ON SCOPE.

COSTS AWARD: IN PLANNING APPEALS, IF EITHER PARTY HAS BEHAVED UNREASONABLY AND THE OTHER PARTY HAS INCURRED UNNECESSARY COSTS AS A RESULT, AN APPLICATION FOR COSTS CAN BE MADE TO THE INSPECTOR. IF THE LPA REFUSED WITHOUT GOOD REASON (E.G., REFUSING A PD-COMPLIANT SCHEME) AND THE APPEAL IS ALLOWED, THE APPELLANT MAY BE AWARDED COSTS AGAINST THE LPA.

APPEAL TIMESCALES: WRITTEN REPRESENTATION HOUSEHOLDER APPEAL: 14 TO 20 WEEKS FROM SUBMISSION TO DECISION. FAST-TRACK: APPROXIMATELY 6 WEEKS. HEARING OR INQUIRY: 24 TO 40 WEEKS.

AN APPEAL IS NOT ALWAYS THE BEST ROUTE AFTER A PLANNING REFUSAL. THE ALTERNATIVES SHOULD BE CAREFULLY CONSIDERED.

REVISED APPLICATION (FREE RESUBMISSION WITHIN 12 MONTHS): FOR HOUSEHOLDER PLANNING APPLICATIONS, IF A REVISED APPLICATION IS SUBMITTED WITHIN 12 MONTHS OF THE DATE OF THE ORIGINAL REFUSAL AND ADDRESSES THE REASONS FOR REFUSAL, THE RESUBMISSION IS FREE OF THE STANDARD PLANNING APPLICATION FEE. THIS IS A COST-FREE ROUTE TO ADDRESSING DESIGN OR SCOPE ISSUES IDENTIFIED IN THE REFUSAL WITHOUT THE TIME AND COST OF AN APPEAL.

PRE-APPLICATION ADVICE: MOST LONDON LPAS OFFER PRE-APPLICATION ADVICE — A PAID SERVICE WHERE A PLANNING OFFICER REVIEWS A SCHEME IN ADVANCE OF FORMAL SUBMISSION AND PROVIDES FEEDBACK ON LIKELY ACCEPTABILITY. FEES VARY BY BOROUGH AND SCHEME SIZE (TYPICALLY £100 TO £600 FOR HOUSEHOLDER PRE-APPLICATION ADVICE). PRE-APPLICATION ADVICE CAN REDUCE REFUSAL RISK AND AVOID THE NEED FOR AN APPEAL.

PERMITTED DEVELOPMENT ROUTE: WHERE A PLANNING APPLICATION HAS BEEN REFUSED, THE QUESTION OF WHETHER THE DEVELOPMENT (OR A MODIFIED VERSION OF IT) COULD BE BUILT AS PERMITTED DEVELOPMENT SHOULD BE ASKED. A LAWFUL DEVELOPMENT CERTIFICATE (LDC) APPLICATION CONFIRMS THAT A SCHEME IS PD WITHOUT REQUIRING FULL PLANNING PERMISSION. IF THE REFUSED SCHEME IS SLIGHTLY OVER THE PD THRESHOLDS, A MODIFIED DESIGN WITHIN PD LIMITS COULD BE PROGRESSED WITHOUT ANY FURTHER PLANNING APPLICATION.

REVIEWING PLANNING INSPECTORATE APPEAL DECISIONS FOR LONDON HOUSEHOLDER APPEALS REVEALS A NUMBER OF RECURRING GROUNDS ON WHICH APPEALS ARE ALLOWED.

INCONSISTENCY WITH COMPARABLE APPROVED SCHEMES: THE SINGLE MOST POWERFUL GROUND. WHERE AN INSPECTOR CAN FIND TWO OR THREE COMPARABLE EXTENSIONS IN THE SAME STREET OR AREA THAT HAVE BEEN APPROVED, THE PRINCIPLE THAT THE DEVELOPMENT PLAN SUPPORTS THE SCALE AND FORM OF DEVELOPMENT IS WELL-EVIDENCED. APPELLANTS SHOULD ALWAYS RESEARCH PLANNING SEARCH DATA FOR THEIR STREET AND SURROUNDING AREA BEFORE SUBMITTING AN APPEAL.

OVERRELIANCE ON NEIGHBOUR OBJECTIONS BY LPA: WHERE THE LPA'S REFUSAL REPORT SHOWS HEAVY RELIANCE ON THE VOLUME OF NEIGHBOUR OBJECTIONS (AS OPPOSED TO THE MATERIAL PLANNING SUBSTANCE OF THOSE OBJECTIONS), AN INSPECTOR IS LIKELY TO ASSESS THE SCHEME ON ITS MERITS AGAINST PLANNING POLICY — AND MAY FIND THAT THE SCHEME COMPLIES.

FAILURE TO APPLY NPPF CORRECTLY: THE NPPF PARA 130 STATES THAT PLANNING PERMISSION SHOULD BE REFUSED FOR DEVELOPMENT OF POOR DESIGN THAT FAILS TO TAKE OPPORTUNITIES FOR IMPROVING CHARACTER AND QUALITY OF THE AREA — BUT IT ALSO STATES THAT PERMISSION SHOULD NOT BE REFUSED FOR SCHEMES THAT ARE NOT POLICY-COMPLIANT IN MINOR RESPECTS. WHERE AN LPA HAS APPLIED DESIGN POLICY TOO RIGIDLY OR INCONSISTENTLY WITH THE NPPF, AN APPEAL INSPECTOR IS LIKELY TO TAKE A MORE BALANCED VIEW.
