Home · Guides · Lightning protection conditions on UK planning decision notices

Where lightning protection wording appears

• Numbered conditions — binding if printed on the sealed notice.
• Industrial and warehouse schemes — cross-read fire safety and building safety conditions.
• Approved drawings — approved plans conditions may fix roof plant that interacts with air terminals.
• Telecoms and mast sites — may overlap telecommunications mast conditions.

Common condition phrases

Timing labels

Lightning protection approval is frequently prior to first occupation or prior to connection of permanent electrical services — pair with pre-commencement vs pre-occupation and how to read condition timing.

Officer reports discuss risk narratively — binding text is the sealed notice when issued.

See pre-commencement vs pre-occupation, how to read condition timing, and decision notice vs officer report.

Renewables and rooftop plant overlap

Solar arrays and rooftop plant may constrain air terminal routes — read renewable energy solar conditions alongside LPS lines.

Materials conditions on visible down conductors may fix colour and fixings — read materials condition wording when LPS is surface-mounted.

Cross-read renewable energy solar conditions and materials condition wording.

Worked example

A warehouse notice might include:

• Condition 9 (prior to first occupation): “No building shall be occupied until details of the lightning protection system, including air terminals and bonding arrangements, have been submitted to and approved in writing.”
• Condition 22 (ongoing): “The lightning protection system shall be maintained and tested in accordance with the approved details.”

Programme literacy: design approval tracks Condition 9; maintenance and test cycles track Condition 22 after handover.

Common misreadings

• Building regulations approval treated as planning LPS discharge. Separate workstreams.
• Indicative roof layout assumed to satisfy LPS tests without submission. Read approval triggers.
• Informative on BS EN citation treated as optional. Only numbered conditions bind — see informatives vs numbered conditions.
• Fire alarm condition assumed to cover lightning protection. Read fire safety conditions separately.

Condition triage checklist

DecisionBrief organises condition lists from the notice you name; it does not replace lightning protection engineers or electrical designers.

Store the PDF reference your LPA portal issued — portal summaries sometimes omit condition numbers present only on the sealed attachment.

Drainage and structural crossover

Lightning down conductors may fix to cladding or structural columns governed by other conditions — programme drainage and structural submissions separately.

Contaminated land remediation conditions may delay superstructure works that LPS design assumes — read contaminated land remediation conditions on brownfield sites.

See drainage and flood risk conditions and contaminated land remediation conditions.

Delegated permissions and sealed notice hygiene

Officer-delegated permissions bind in the same way as committee grants — read delegated vs committee wording only to confirm you hold the sealed instrument.

Thin or missing sealed notices make LPS triggers hard to confirm — see thin or missing sealed decision notice when portal HTML is incomplete.

See delegated vs committee wording, where to find the sealed notice, and thin or missing sealed decision notice.

Heritage and industrial retrofit context

Listed buildings and conservation areas may constrain surface-mounted down conductors — programme heritage listing conservation conditions before fixing LPS routes on historic facades.

Archaeology conditions on brownfield warehouses may delay ground works that LPS earthing assumes — read archaeology condition wording on sensitive sites.

See heritage listing conservation conditions and archaeology condition wording.

Waste and construction compound interfaces

Temporary generators on construction compounds may require interim LPS bonding before permanent building LPS is approved — read temporary construction compound conditions when build programmes split handover stages.

Waste management conditions may fix locations for flammable storage that LPS designers must coordinate — read waste management conditions on industrial estates.

See temporary construction compound conditions and waste management conditions.
