What does a Solar PV Structural Engineer do?
A solar PV structural engineer assesses whether an existing commercial roof can carry the static and dynamic loads of a proposed photovoltaic array. The assessment is calculated to BS EN 1991-1-3 (snow), BS EN 1991-1-4 (wind, with UK National Annex), BRE Digest 489 (PV-specific wind coefficients) and the relevant Building Regulations duty (Approved Document A in England and Wales). Reports are signed by a qualified structural engineer, accepted by lenders and planning authorities. Solar Surveys Ltd works to a 48-hour benchmark from the site visit, or from complete information for desktop reports.
What We Deliver
Four core services. One engineering team.
Every commercial solar PV project we touch starts with a structural engineering decision. The four core services below cover the full pre-construction structural pipeline from desktop structural roof loading reports to on-site structural surveys to drone-supported condition assessment to design.
01 . On-Site
Structural Surveys for Solar PV

02 . Aerial
Drone Roof Condition Assessment
BDF and BMFA accredited drone pilots, £25M public liability. Engineer-reviewed aerial condition assessment. No scaffold required. Combined with structural survey on the same site visit.
03 . Remote
Desktop Structural Roof Loading Reports
Eurocode-verified structural assessment without a site visit. From £130 per report. Lender and MCS-accepted format. 48-hour benchmark from receipt of complete information. Used for portfolio programmes and pre-design diligence.
04 . Design
Solar PV Design and G99 Support
In-house solar PV CAD layout, G99 and G98 DNO application support, electrical survey integration. Engineer-produced design packages compatible with Eurocode-verified structural sign-off.

Engineering Certainty
Why a specialist structural engineer for your solar PV project.
A roof condition survey records the coverings, fixings and drainage. A structural assessment for solar panels calculates whether the frame, purlins and connections can carry the array under permanent, imposed, snow and wind loads, and states a determination. Many commercial projects need both, and we deliver them under one instruction. The wind uplift calculation chain (BS EN 1991-1-4 with UK National Annex, plus BRE Digest 489 PV-specific coefficients) is the most consequential single load case for rooftop PV. A standard Eurocode wind reading without the BRE Digest 489 PV layer understates uplift on the array.
For ballasted flat-roof systems, MIS 3002 V6.0 Section 5.9.13(h) makes structural engineer consultation an absolute requirement. There is no discretion. Solar Surveys Ltd is a UK structural engineering practice for rooftop solar panels and solar PV, and provides that engineer.
Reports are signed by qualified structural engineers, formatted for lender acceptance, and issued to a 48-hour benchmark from the site visit, or from complete information for desktop reports.

Frequently Asked Questions
Structural Engineer Questions.
Do I need a structural engineer for solar panels in the UK?
For commercial rooftop solar PV, yes. The Building Regulations Approved Document A duty applies to every rooftop PV installation. For sub-50kWp DC systems within MCS scope, MIS 3002 V6.0 Section 5.9.6 makes a qualified structural engineer mandatory if the roof has any of: hipped geometry, valley geometry, asymmetric duo-pitched form, dormers, parapets, pitch below 30 degrees, or visible structural distress. For flat-roof ballasted systems, Clause 5.9.13(h) makes engineer consultation absolute regardless of size. For commercial systems above 50kWp, MCS does not apply but Eurocode 1 calculations and Building Regulations duty remain.
How quickly can a structural engineer deliver a survey for solar PV?
Solar Surveys targets 24-hour mobilisation on on-site structural surveys for priority instructions, with a signed report to a 48-hour benchmark from the site visit. Desktop Structural Roof Loading Reports involve no site visit: they are issued to a 48-hour benchmark from receipt of complete information. Quotes are issued to a 24-hour target from enquiry. Volume programmes are absorbed into the same delivery cadence at portfolio scale.
What standards does a structural survey for solar PV need to satisfy?
For UK commercial PV in 2026, the binding framework is Eurocode 1 (BS EN 1991-1-3 snow, BS EN 1991-1-4 wind with UK National Annex), BS EN 1990 load combinations, BRE Digest 489 (2014) for PV-specific wind coefficients, and Building Regulations Approved Document A. For sub-50kWp segments within MCS scope, MIS 3002 V6.0 Section 5.9 also applies, mandatory from 18 June 2026. BS 6399-2:1997 was withdrawn in 2010 and is no longer a valid reference standard.
How much does a structural survey for solar PV cost?
Desktop Structural Roof Loading Reports start from £130 per report. Combined on-site structural survey and drone roof condition assessment programmes start from £600 per building, varying by roof count and complexity. Volume programmes from 10 sites attract structured discounts. Full pricing on the pricing page.
Do you cover the whole UK?
Yes. Solar Surveys operates across England, Scotland, Wales and Northern Ireland from Glasgow HQ, with 24-hour mobilisation target across all 12 city pages above. Northern Ireland and Republic of Ireland coverage included. European deployment available for client-instructed projects.
Can the structural survey be combined with a drone roof condition assessment?
Yes. The two services are commonly instructed together on a single site visit. Structural calculations and aerial roof condition findings are produced as a unified report. Drone pilots are BDF and BMFA accredited with £25M public liability. Read more on the drone roof survey page.
Will the report be accepted by lenders and planning authorities?
Reports are produced in formats routinely accepted by institutional lenders and local planning authorities. The standards anchor (Eurocode 1, Building Regulations Approved Document A, MIS 3002 V6.0 where applicable) and engineer signature satisfy the documented structural-evidence requirement under MIS 3002 V6.0.
What client types do you typically work with?
Asset managers running portfolio-scale solar PV programmes, PPA providers requiring lender drawdown sign-off, EPC contractors needing pre-construction structural diligence, MCS-licensed solar installers, and housing developers installing PV across new build and existing residential portfolios. Audience-specific pages are linked in the Who We Serve menu.
