Guesswork is the most expensive part of a renewable energy project. A feasibility survey establishes what your roof or land can carry, how much it will generate, and how that generation lines up against the way you actually use power.
What a solar feasibility survey involves
A solar feasibility survey assesses whether a property or site is suitable for solar PV, and if so, what size and configuration of system would work best. We look at roof orientation, pitch, shading, structural condition, available roof or land space, and your existing electrical infrastructure. We then model likely generation against your actual consumption data, so you get a realistic picture of how a system would perform before any design or costing work is finalised.
Who it is for
Feasibility surveys suit homeowners and businesses who want to understand whether solar is worthwhile for their property before committing to a full design and quotation. This includes commercial and public sector organisations assessing solar as part of a wider energy strategy, landlords and property managers weighing up options across a portfolio, and anyone with a complex roof, shading, or site that needs proper assessment rather than a desktop guess. We have worked with organisations including Premier Inn, the NHS, Greater Manchester Police and Greater Manchester Fire Service, alongside domestic customers across the region.
When it is needed
A feasibility survey is the right first step when you are considering solar but are not yet ready to commit to installation, when a roof has awkward orientation, multiple pitches or shading that makes a simple online estimate unreliable, or when a business needs generation modelling to support an internal business case or funding application. It is also useful ahead of a roof replacement, extension or new-build, where designing solar in from the outset avoids costly retrofitting later.
Why professional assessment matters
Online solar calculators cannot account for real shading patterns, roof structure, local network capacity or your actual half-hourly consumption profile. A generic estimate can significantly overstate or understate what a system would actually generate and save. A proper site survey and generation model, carried out by the same MCS certified team that would go on to design and install the system, gives you numbers you can actually rely on when deciding whether to proceed.

What it costs to wait
What happens when this is left alone
Relying on desktop estimates alone
Satellite-based or desktop-only estimates cannot see local shading from chimneys, trees or neighbouring buildings, or assess the actual condition of your roof structure. Decisions made on this basis alone can lead to a system that underperforms against expectations, or a business case built on numbers that do not hold up once installation begins. Our surveys are carried out on site, not from a desk.
Committing before checking site constraints
Roof condition, available structural capacity, and existing electrical infrastructure all affect what is actually achievable on a given site. Committing to a system size or budget before these are checked can mean discovering mid-project that the roof needs remedial work first, or that the electrical supply needs upgrading, adding cost and delay that a feasibility survey would have flagged early.
Generation modelling that ignores your consumption
A system sized purely on available roof space, without matching generation against your actual consumption pattern, can end up oversized relative to what you use during daylight hours, reducing the value of the investment. Our modelling is built around your real consumption data wherever it is available, not a generic assumption of how a typical household or business uses electricity.
Our process
How we deliver the work
- 01
Initial information gathering
We ask for your energy bills, full address and postcode, and any information you have on your roof or site, so we can prepare for a targeted site visit rather than a generic once-over.
- 02
Free site survey
We visit your property or site to assess roof orientation, pitch, shading, structural condition, available space and your existing electrical setup, checking everything that would affect a future installation.
- 03
Generation modelling
Using the survey data and your consumption data, we model expected generation and how it would align with your usage pattern, giving you a realistic picture rather than a generic estimate.
- 04
Feasibility findings and options
We present the findings clearly, covering suitability, indicative system size and configuration, and any site constraints identified, along with any recommended remedial work.
- 05
Written quotation, if you proceed
If you decide to move forward, we produce a full written quotation covering specification, funding route and timescales, typically within 1–2 working days of the survey.
Benefits
What this changes for you
Free and no-obligation
The feasibility survey and generation modelling are provided free of charge, with no obligation to proceed to installation. You get a clear, honest assessment before you commit any budget.
On-site assessment, not a desktop guess
Every survey is carried out on site by our own team, checking roof condition, shading and electrical infrastructure in person rather than relying on satellite imagery alone.
Modelling based on your real consumption
Where consumption data is available, generation modelling is built around your actual usage pattern, so the picture you get reflects how a system would perform for your property or business specifically.
One team from feasibility to installation
The same in-house team of around ten people that carries out your feasibility survey also handles design, installation and commissioning, so nothing is lost in translation between assessment and delivery if you choose to proceed.
MCS certified assessment
As an MCS certified installer for solar PV and battery storage, our feasibility work is grounded in the same standards used for the eventual installation, not a generic sales estimate.
Clear next steps either way
If a site is not suitable, or only suitable with remedial work first, we tell you plainly. If it is suitable, you receive a written quotation typically within 1–2 working days, so you always know where you stand.
In detail
Feasibility Surveys & Energy Assessments explained properly
What the survey physically checks
The site visit covers roof orientation and pitch, shading from chimneys, trees, dormers and neighbouring buildings across the day and across seasons, roof covering type and structural condition, available roof or ground space, and the condition and capacity of your existing consumer unit and electrical supply. For commercial sites, we also assess access, scaffolding requirements and any structural loading considerations for larger arrays.
How generation modelling works
We combine the physical survey data, including roof angle, orientation and shading, with local solar irradiance data and your consumption profile to model expected generation across the year. Where half-hourly or historic consumption data is available, we use it directly, giving a far more accurate picture than a flat annual estimate. This modelling underpins any system sizing recommendation that follows.
Variations for different site types
Domestic feasibility surveys typically focus on a single roof with one or two orientations and a fairly predictable consumption pattern. Commercial and public sector feasibility work often involves multiple roof planes or ground-mount options, higher and more variable daytime consumption, and a business case that needs to stand up to internal scrutiny or funding requirements, which our modelling and reporting are built to support.
Common findings and constraints
Typical issues identified during feasibility surveys include partial shading that reduces usable roof area, roof coverings needing repair or replacement before panels could be fitted, electrical supplies needing upgrading to support a larger system, and consumption patterns that would suit a smaller array with battery storage rather than maximising panel numbers. Identifying these at feasibility stage avoids surprises during installation.
Residential versus commercial feasibility
Domestic feasibility surveys are generally quicker to complete and focus on whether solar makes sense for a single property's roof and consumption. Commercial and public sector feasibility work tends to be more involved, covering larger or multiple roof areas, more complex electrical integration, and funding routes structured through commercial finance, a Power Purchase Agreement or CAPEX purchase, since we do not currently offer a domestic finance product.
Common questions
Questions about feasibility surveys & energy assessments
Is the feasibility survey really free?
Yes. The site survey and generation modelling are provided free of charge and with no obligation to proceed to installation.
What do I need to provide before the survey?
We ask for your energy bills, full address and postcode so we can prepare properly. If you have any information on your roof, existing electrics or previous quotes, that helps too, but is not essential.
How is a feasibility survey different from an online solar calculator?
An online calculator relies on satellite imagery and generic assumptions and cannot account for real shading, roof structure or your actual consumption pattern. Our survey is carried out on site by our own team and the generation model is built around your real data wherever it is available.
How long does the survey take?
The site visit itself typically takes a short amount of time depending on the size and complexity of the property or site. Findings and any generation modelling are then prepared and, if you wish to proceed, a written quotation is typically returned within 1–2 working days.
What happens if my site is not suitable for solar?
We will tell you plainly if a site is not suitable, or only suitable subject to remedial work such as roof repairs or an electrical upgrade. There is no obligation to proceed and no pressure either way.
Can you model generation for a commercial or public sector site?
Yes. We carry out feasibility work for commercial and public sector sites, modelling generation against site-specific consumption data to support internal business cases or funding decisions.
Do you cover feasibility surveys across the North West?
Yes. We cover Lancashire, Merseyside, Cheshire and Greater Manchester, including Preston, Ormskirk, Southport, Liverpool, Warrington, Chester, Wigan and Bolton, from our base at Westhead near Ormskirk.
If the survey shows solar is suitable, what happens next?
We move straight into a full written quotation covering system specification, panel, inverter and battery options, warranty terms and funding route, typically within 1–2 working days of the survey.
