Standard commercial viability file
Standard commercial viability file, £49.
A printable decision-support memo built from the saved commercial check assumptions. It helps organise rent burden, cash pressure, downside risk, evidence gaps, lease questions, and any rent-free period, deposit, or fit-out incentive before you sign. It is unlocked from a saved result, then opens as a memo you can print or save as PDF. If your assumptions change, rerun the free commercial check so the file reflects the latest numbers. It can also frame business-type assumptions such as covers, orders, appointments, footfall, stock margin, and chair utilisation where relevant.
Quick answer
The £49 Standard Commercial Viability File turns the free check into a printable decision memo with assumptions, stress tests, lease questions, evidence prompts, and a clear view of what still needs verifying before signing. It is useful when the site deserves a deeper read but you want the numbers organised first, including location prompts such as nearby rent evidence, business rates, EPC, and building-condition assumptions.
That makes it easier to think in the language of the business: covers, orders, appointments, footfall, stock margin, or chair utilisation, rather than only the headline rent. If you enter a postcode or address, it also keeps the local evidence prompts in view rather than leaving the file at a generic rent ratio.
If you are still comparing sites, start with the commercial lease checklist before signing. The same issues then appear in the paid memo as cost, cash, and exit checks.

Needs caution: rent burden is high and the opening buffer is thin.

Whether the site survives six weak trading months
The downside month covers known operating costs, but a £9k opening buffer is thin relative to setup risk and early trading friction.
Value comparison
Spend £49 before you spend £2,500+.
Professional lease reviews, surveys and pre-signing checks can quickly cost £2,500+ before you commit to a site. YieldLens gives you a £49 first-pass viability screen so you can pressure-test rent burden, opening cash, break-even pressure and downside risk before deciding whether to take the lease further.
Important limits
YieldLens does not replace solicitors, surveyors, valuations or professional due diligence. It helps you test whether the numbers are worth taking further.
Professional costs vary by lease, property, location and scope. £2,500+ is an indicative comparison for legal review, surveys and pre-signing checks, not a guaranteed cost or saving.
Why the £49 file exists
The Standard file turns the free snapshot into a printable decision memo.
The free check gives the fast view. The £49 file organises the same result into a decision memo before you spend more on legal review, surveys, and professional due diligence.
If a rent-free period or fit-out incentive is part of the deal, see commercial rent-free periods before signing for the timing and cash impact before you commit.
What it does not do
What the file does, and what it does not do.
The page stays clear about the product boundary so users know what they are buying.
What do I get for £49?
- • A printable decision-support memo
- • An assumption review linked to the saved result
- • Stress-test interpretation and downside context
- • Negotiation levers, evidence checklist, and lease questions
What it will not tell you
- • It does not value property.
- • It does not review lease documents.
- • It does not verify sales assumptions.
- • It does not check legal liability, planning, licensing, or tax issues.
- • It does not replace a solicitor, surveyor, accountant, or professional adviser.
Use estimates if you are still comparing units. The file is useful when the deal looks promising but you want to understand rent pressure, opening cash, weak-start risk, and whether an incentive like a rent-free period or deposit actually changes the picture before committing.
Methodology proof
The memo is built from practical lease pressure points.
Why the checks matter
Rent burden checks affordability pressure. Break-even customers check trading realism. Opening cash checks setup strain. Business rates and service charge can move the cost base. Lease length shapes commitment risk. Assignment and subletting affect exit flexibility. Permitted use can stop the concept before it starts. Downside survival checks weak-start resilience. Rent-free periods and fit-out incentives can change the cash picture. The evidence checklist reduces assumption risk.
What the memo helps you do
It helps the user see what to challenge before signing, what to verify, and where negotiation effort is most likely to change the result.
Illustrative example
A fictional cafe lease becomes easier to judge once the levers are visible.
This is not a real case. It shows the kind of pressure-test the paid memo is built to organise.
Before negotiation
- High rent burden
- Thin opening buffer
- Demanding break-even customers
- Weak downside survival
Possible improvements
- Rent-free period
- Lower deposit
- Staged fit-out
- Landlord contribution
- Better revenue evidence
Free vs paid
The free check gives the numbers. The paid file turns them into a decision memo.
The comparison below keeps the offer honest. The free check is the screen. The paid file is the printable pressure-test and action plan. The sample file is a separate redacted example, not the same case as the homepage sample.

Important limits
What it is not
This distinction matters. YieldLens UK is a decision-support tool for early screening, not a regulated advice service or a substitute for professional due diligence.
Business-type rent checks
Use the page that matches the unit type.
The Standard commercial viability file sits alongside the business-type affordability checks.
Unlock the Standard Commercial Viability File from your result
Run a free commercial check first, then unlock the Standard Commercial Viability File from the results page.
The check creates the saved result that powers the file. From the results page, you can unlock the Standard commercial viability file for that result or view the separate redacted sample file first.
