How it works

Postcode plus three roof inputs. Server-side engine matches your postcode to a snow zone, applies altitude correction, calculates the combined design load against indicative capacity, returns Green, Amber, or Red.

  • Postcode → snow zone + altitude
  • Roof type → shape coefficient
  • Material → dead load
  • Combined ULS load check
  • Verdict band returned

Email-gated before the result. Verdict shown on screen and emailed to the address you provide.

Standards applied

  • BS EN 1991-1-3 + UK NA (snow)
  • BS EN 1991-1-4 + UK NA (wind)
  • BS EN 1991-1-1 Annex A (dead loads)
  • BS EN 1990 (load combinations)
  • MIS 3002 V6.0 §5.5.5(b)
  • BRE Digest 489 (PV-specific)

Same Eurocode anchor for MCS-licensed (sub-50kWp) and commercial portfolio assessments.

Top three questions

Is this enough? No. Indicative only. The documented assessment is what installers, insurers, lenders, and building control require.

Commercial or MCS? Both. Same screening, same standards, same routing.

Whatever the screening result, the documented structural assessment is the deliverable.

Fixed-fee. Quote within 24 hours of enquiry. Delivered within 48 hours from confirmed scope. Qualified structural engineer sign-off. For MCS-licensed installations under MIS 3002 V6.0 and for commercial portfolios under PPA finance / Technical Advisor / insurer review.

WHY COMMISSION THE DOCUMENTED ASSESSMENT

For MCS-licensed installations, the documented structural assessment is mandatory from 18 June 2026. For commercial portfolios, it unlocks PPA finance, lender Technical Advisor sign-off, and insurer cover. The pre-check tool is the funnel. The documented assessment is what closes the deal.

WHO USES THIS TOOL

Equal weight: commercial and MCS-licensed.

Asset managers and PPA developers

Portfolio screening at scale. Pre-due-diligence on candidate sites before commissioning documented assessments. Unlocks PPA finance and Technical Advisor sign-off.

EPC and construction contractors

Early-stage feasibility filtering on solar tender opportunities. Triages which sites warrant full documented assessment before bid pricing locks.

MCS-licensed installers

Pre-screening sites before quoting. Triages which projects need documented structural assessment under MIS 3002 V6.0 Section 5.5.5(b), mandatory from 18 June 2026.

Commercial occupiers and homeowners

Understanding structural feasibility on your roof. Indicative screening signed off by Solar Surveys — useful before quoting installers, lenders, or insurers.

WHAT YOU GET WHEN YOU COMMISSION

The documented structural assessment.

Six deliverables in the documented assessment package. Single fixed fee. Quote within 24 hours of enquiry. Delivered within 48 hours from confirmed scope.

01 · Calculation

Eurocode load calculation

Site-specific snow, wind, dead load, and PV load combined per BS EN 1990 ULS. Numerical capacity check against the actual roof structure.

02 · Engineering

Drift and exposure analysis

Site-specific drift geometry at the panel array. Exposure factor calculated for your roof, not a generic terrain category.

03 · Roof condition

Existing roof condition statement

Roof structure condition, fixings, and known defects assessed. Foundation transfer and load path continuity verified.

04 · Compliance

MIS 3002 V6.0 evidence

Compliance evidence under Section 5.5.5(b) for MCS-licensed installations. Equivalent compliance under commercial / PPA / TA review requirements.

05 · Sign-off

Qualified structural engineer sign-off

Signed by a qualified structural engineer. £5M Professional Indemnity cover. Independent qualified structural sign-off.

06 · Delivery

48-hour turnaround. Fixed fee.

Quote within 24 hours of enquiry. Delivered within 48 hours from confirmed scope. Single fixed fee. No hourly creep. Forward-ready for installers, insurers, lenders, and building control.

FREQUENTLY ASKED QUESTIONS

Pre-Check Questions.

What does the screening result mean?
The screening returns Green (indicative capacity clear), Amber (conditional, sensitive to factors not measured in the screening), or Red (indicative capacity exceeded). The result is a starting point, not a structural assessment.
Is this screening enough to satisfy MIS 3002 V6.0 for MCS-licensed installations?
No. The screening is indicative only. MIS 3002 V6.0 Section 5.5.5(b), mandatory from 18 June 2026, requires a documented structural assessment and wind loading calculation as evidence on file. The widget does not produce that document. A Solar Surveys documented structural assessment does.
Can commercial portfolio buyers use this?
Yes. The same indicative screening applies. Commercial portfolio screening at scale, PPA finance pre-due-diligence, lender Technical Advisor sign-off, and insurer cover for solar PV all reference the same documented structural assessment that the screening routes you toward.
How is the screening different from the documented structural assessment?
The screening uses postcode-level snow and wind data, generic shape coefficients, and indicative dead-load values to return a directional result in under 60 seconds. The documented structural assessment includes site-specific drift geometry, exposure factor calculation, roof condition assessment, foundation transfer analysis, and signed-off compliance evidence produced by a qualified structural engineer.
What standards does the screening use?
BS EN 1991-1-3 with UK National Annex for snow, BS EN 1991-1-4 with UK National Annex for wind, BS EN 1991-1-1 Annex A for material dead loads, BS EN 1990 for load combinations. MIS 3002 V6.0 Section 5.5.5(b) is the regulatory anchor for MCS-licensed installations; the same standards anchor commercial portfolio assessments.
What do I receive from the screening?
On screen: the verdict band, engineering reasoning, capacity bar, four-cell summary of the calculation, and the regulatory anchor. By email: the verdict, your reference number, and the engineering reasoning so you can forward the result to installers, asset managers, lenders, insurers, or building control.
When is the documented structural assessment essential?
The documented structural assessment sits on file for the lifetime of the installation. Insurance claims, building-control queries, future remortgage surveys, lender refinance reviews, and asset-portfolio audits all reference it. Solar Surveys is the specialist structural engineering firm that installers, asset managers, EPCs, and commercial occupiers commission to produce this evidence. Qualified structural engineer sign-off, MIS 3002 V6.0 compliant. Quote within 24 hours of enquiry. Delivered within 48 hours from confirmed scope.
How long is the screening result valid?
The screening result has no fixed expiry on its own. The regulatory framework it cites, MIS 3002 V6.0, becomes mandatory from 18 June 2026 for MCS-licensed installations. The documented structural assessment, by contrast, is valid for the lifetime of the installation as designed.
What happens to my data?
Your email is held by Solar Surveys Ltd only and is not shared with third parties. The screening result and your reference number are emailed to you. Solar Surveys may follow up once with information about the documented structural assessment. Full privacy policy at /privacy-policy/.
