Pre-Construction That
Protects Your Margin
on Every Site.

An independent structural survey protects the EPC contractor from liability arising from roof loading assumptions. UK Building Regulations require structural adequacy to be demonstrated before any rooftop solar PV installation proceeds; for commercial PV this means a Eurocode-verified appraisal by a qualified structural engineer. Without this, lender drawdown conditions may not be met. For sub-50kWp installations within MCS scope, MIS 3002 V6.0 Section 5.9 also applies and MCS certification cannot be issued without the engineer-signed appraisal.

The package covers structural survey, roof condition assessment, CAD layout drawing, electrical survey and G99 application. Delivered as a single programme output by one engineering team: no coordination overhead, one report format, one point of contact. All outputs are produced in-house and benchmarked at 48 hours from site visit.

Reports are delivered in a consistent format compatible with standard EPC programme schedules. We work to your programme milestones: Desktop Structural Roof Loading Reports can be issued within 24 hours of instruction for pipeline screening, with on-site surveys scheduled to your mobilisation window. Volume programmes are managed with a dedicated schedule and direct account manager contact.

We handle both. Single-site commissions receive the same named engineer, report format and 48-hour delivery benchmark as volume programmes. For EPC contractors managing pipeline batches of 10 or more sites, we provide programme-level management with dedicated scheduling, consistent report formatting and priority mobilisation.

Yes. The design package is built directly on our structural survey findings by the same in-house engineering team. Panel layout, setback zones and fixings positions are confirmed against the actual load-bearing capacity identified during the survey. This eliminates the redesign risk that occurs when a separate design firm works from survey data they didn't produce.

A Drone Technical Survey is required where the structure is industrial, large-span or where the cladding system is complex: warehouses, distribution centres, manufacturing plants and similar building types. The technical survey provides detailed facade condition data, penetration mapping and substrate integrity classification that a standard drone roof condition assessment does not cover. It is conducted alongside the on-site structural survey under the same instruction, with outputs delivered in the same 48-hour benchmark.

MIS 3002 V6.0, issued 18 March 2026 and mandatory from 18 June 2026, requires a suitably qualified engineer to confirm structural adequacy before any rooftop commercial solar PV installation proceeds. For EPC contractors, this means obtaining a structural engineer-signed report that addresses the specific requirements of MIS 3002 V6.0 Section 5.9 before mobilising installation resource. Desktop Structural Roof Loading Reports from Solar Surveys satisfy this requirement for eligible building types. For sites triggering a mandatory on-site assessment, see On-Site Structural Surveys.

The EPC contractor typically holds the Principal Contractor role under the Construction (Design and Management) Regulations 2015 on a commercial solar PV installation. CDM 2015 requires the Principal Contractor to ensure that design outputs are structurally adequate before work commences. An engineer-signed structural report from Solar Surveys directly satisfies this obligation and forms part of the health and safety file required under CDM 2015.

Desktop Structural Roof Loading Reports are delivered within a 48-hour benchmark from receipt of instruction. For EPC contractors clearing a pipeline of 10 or more sites, batch screening via desktop reports identifies which sites require on-site structural surveys before installation resource is mobilised. This prevents late-stage programme delays caused by structural unknowns discovered on site. See Desktop Reports for the full scope and pricing.

G99 connection applications submitted to the DNO require confirmation that the roof structure can support the proposed installation, particularly for larger commercial systems where the structural load calculations form part of the design package review. Solar Surveys produces the structural engineer-signed documentation required for G99 submission alongside the on-site survey or desktop report, under the same instruction. G99 application management is handled in-house by the same engineering team.

Yes. Every structural report produced by Solar Surveys is signed by a qualified structural engineer and formatted to satisfy MIS 3002 V6.0 Section 5.9 requirements. The report provides the pass, conditional or fail determination, the supporting load calculations and the engineer’s declaration required by MCS certification bodies. For EPC contractors managing multiple sites, consistent report formatting across the entire batch is maintained as standard.
