Free Solar Survey & Quote in Glasgow: What Happens and Why It's the Essential First Step
Every successful solar installation in Glasgow begins with one thing: a professional, no-obligation solar survey. Yet many homeowners don’t know what to expect from this visit — or why it matters so much. This guide explains exactly what happens during a free solar survey with Solar Installers Glasgow, what questions to ask, and why skipping this step (or choosing a surveyor who rushes it) can cost you thousands.
What Is a Free Solar Survey?
A solar survey is a detailed assessment of your property carried out by a qualified, MCS-accredited surveyor. It is completely free and carries no obligation to proceed. The purpose is to determine:
Whether your roof is structurally and technically suitable for solar panels
Which system size will maximise your return on investment
Your projected annual energy generation, savings, and SEG income
Any planning or building considerations specific to your property
Solar Installers Glasgow has surveyed thousands of Glasgow properties — from Victorian terraces in the West End to modern new-builds in Pollokshields and detached homes in Bearsden. Every survey is carried out by an experienced, NICEIC-certified engineer — not a sales representative.
What Happens During Your Solar Survey?
Stage 1: Roof Assessment (20–30 minutes on-site)
The surveyor will examine:
Assessment PointWhat We’re Looking ForWhy It MattersRoof orientationSouth / East / West facingDetermines annual output — south yields up to 20% moreRoof pitchAngle between 15° and 50°Affects panel mounting and output optimisationRoof conditionAge, tile type, structural integrityEnsures panels can be safely and securely mountedShading analysisTrees, chimneys, dormer windows, neighbouring buildingsIdentifies micro-inverter or optimizer needsRoof area availableUsable square metres after obstructionsDetermines maximum system sizeElectrical entry pointLocation of consumer unit/fuse boardAffects installation complexity and cable routing
Stage 2: Energy Consumption Review (10–15 minutes)
The surveyor will ask to see a recent electricity bill or smart meter data. This allows us to:
Model your solar system against your actual usage pattern
Calculate your self-consumption rate (how much solar energy you’ll use directly)
Recommend whether battery storage will materially improve your return
Stage 3: System Recommendation & Output Modelling
Using surveying data and solar irradiance models specific to your Glasgow postcode, our engineers produce a system design that includes:
Recommended panel type, quantity, and layout
Inverter specification
Battery storage recommendation (if appropriate)
Projected annual kWh output
Estimated annual savings and SEG income
Payback period calculation
Stage 4: Quote Presentation
You receive a detailed, written quote within 48 hours. This includes:
Full itemised breakdown (panels, inverter, mounting hardware, cables, labour, scaffolding, certification)
Three package options where applicable (solar only / solar + battery / premium system)

Solar Installers Glasgow surveys tick every green flag. We have a 4.9-star average across Google, Trustpilot, and Checkatrade.
How Long Does the Survey Take?
A thorough solar survey for a typical Glasgow semi-detached home takes approximately 45–60 minutes on-site. For larger detached properties or commercial buildings, allow 60–90 minutes. We will not rush a survey — cutting corners here leads to under-performing systems and disappointed customers.
Do I Need to Prepare Anything?
To get the most from your survey, have the following ready:
A recent electricity bill or smart meter app showing your annual kWh consumption
Access to your loft (for checking roof structure, if needed)
Access to your consumer unit / fuse board
A list of any planned changes — EV charger, extension, hot tub — that will affect electricity usage
Frequently Asked Questions
Q: Is the solar survey really free with no obligation?
A: Absolutely. Solar Installers Glasgow conducts every survey at no charge and with no sales pressure. If your roof isn’t suitable, we will tell you honestly. If you decide not to proceed after receiving your quote, there is no charge and no follow-up pressure.
Q: Can I get a quote without a survey?
A: We can provide a high-level indicative cost range online, but we will not give a firm quote without a survey. Doing so would risk either overcharging you (for a larger system than needed) or underquoting (missing complexity that adds cost). A proper survey protects you.
Q: How quickly can you book a survey in Glasgow?
A: We typically have availability within 3–5 working days across all Glasgow postcodes including the West End, South Side, East End, and surrounding areas including Bearsden, Newton Mearns, Milngavie, and East Kilbride.
