Most UK warehouse solar PV does not need planning permission — it's covered by Permitted Development under Class A Part 14 of the GPDO 2015. This means installation can proceed without formal planning application. There are exceptions — listed buildings, conservation areas, AONBs, and specific local Article 4 Directions — but they apply to a minority of stock.
Permitted Development criteria
Class A Part 14 covers most non-domestic solar PV installations subject to: building must not be listed; site must not be in a Conservation Area, AONB, or World Heritage Site; PV must not be on the principal elevation visible from a highway; PV must not project more than 0.2m above the roof. Most modern UK warehouse stock outside city centres meets all these criteria.
When you do need consent
Listed buildings: Listed Building Consent required regardless of scale. Typical timeline 8-14 weeks for sympathetic warehouse PV installs. Conservation areas: planning application required (typically 8-12 weeks). AONB: planning application + sometimes landscape impact assessment (12-16 weeks). Article 4 Directions: some councils have removed PD rights in specific areas — always check the local Council's adopted Article 4 Directions.
Pre-application engagement
For complex sites, we recommend pre-application engagement with the council planning team. Pre-app fees typically £200-£800. Allows planning officer to flag issues early and reduces formal application risk.
What we do as standard
For every project, we confirm planning route during desk feasibility. For PD projects, we hold the technical evidence (roof drawings, PV layout, structural calculations) ready for any future Council enquiry. For consent-required projects, we manage the full planning process including pre-app engagement.
