About ValuBase
ValuBase is an online business valuation utility designed principally for UK SMEs. It provides a structured analytical tool for estimating the indicative Enterprise Value of established private businesses using financial performance, maintainable EBITDA, market calibration and business-specific characteristics.
In these Terms, references to “ValuBase”, “we”, “us” and “our” refer to the operator of the ValuBase service. The legal entity operating ValuBase is not identified in this application and should be confirmed before formal reliance; please contact us via the Contact page for operator details.
02
Using ValuBase
By accessing or using the website or the valuation tool, you agree to use the service in accordance with these Terms. If you do not agree, you should not use the service. The service is provided without charge and does not require you to create an account.
03
Intended users
ValuBase is intended for:
- business owners
- prospective buyers
- investors
- advisers
- accountants
- corporate-finance professionals
- other commercially experienced users
It is designed primarily for analysis of established private businesses and SMEs. It may not be appropriate for:
- pre-revenue businesses
- start-ups whose value depends principally on future growth
- businesses with zero or negative maintainable EBITDA
- distressed or insolvent businesses
- asset-driven businesses where EBITDA is not an appropriate valuation basis
- highly unusual or complex businesses requiring specialist valuation work
Further detail is set out in the Methodology and Guide pages.
04
Indicative estimate — not a formal valuation
ValuBase does not provide:
- a formal business valuation
- an independent expert valuation
- a fairness opinion
- investment advice
- financial advice
- legal advice
- tax advice
- accounting advice
- regulated financial advice
- due diligence
- transaction advice
- an offer or recommendation to buy or sell a business
- a guarantee of the price obtainable in a transaction
No professional accreditation or regulated status is implied unless and to the extent actually applicable to the operator.
05
ValuBase estimates Enterprise Value
Unless expressly stated otherwise, ValuBase estimates Enterprise Value: the indicative value of the underlying business operations before transaction-specific adjustments for financing and other balance-sheet items.
The price payable for shares may differ after considering items such as:
- cash and cash-like items
- debt
- debt-like liabilities
- working capital
- tax liabilities
- deferred consideration
- transaction-specific adjustments
- due diligence findings
- completion accounts or locked-box adjustments
- other negotiated terms
06
How the valuation is produced
At a high level, the model may use:
- historical financial performance
- EBITDA normalisation
- Maintainable EBITDA
- business-size calibration
- sector / subsector calibration
- business-quality assessment
- customer concentration
- market-conditions adjustments
- professional / manual overrides where available
The methodology is deterministic: the output is generated from the information and assumptions entered into the tool and the valuation methodology implemented within ValuBase. The existence of a structured methodology does not remove professional judgement or uncertainty from private-company valuation.
See the Methodology and Guide pages for further detail.
07
Market calibration and proprietary information
ValuBase uses calibration factors and model parameters intended to reflect observed characteristics of UK SME transactions and business size.
ValuBase does not represent that the model is based on any named number of transactions unless that claim has been independently substantiated and deliberately approved for publication.
08
Your inputs materially affect the result
The valuation is only as reliable as the information and assumptions supplied. Examples of inputs that can materially affect the result include:
- incorrect financial figures
- incomplete normalisation adjustments
- inappropriate EBITDA add-backs
- omitted downward adjustments
- incorrect sector selection
- inaccurate customer concentration
- subjective business-quality scoring
- inappropriate maintainable EBITDA method
- manual valuation assumptions
- market-condition adjustments
- manual multiple overrides
09
Normalisation requires judgement
EBITDA adjustments can materially affect value. Add-backs should not automatically be made merely because an expense is unusual or discretionary. Similarly, downward adjustments may be necessary where reported EBITDA benefits from:
- exceptional income
- below-market owner remuneration
- missing replacement-management cost
- understated rent
- non-recurring benefits
- other unsustainable earnings
An inappropriate normalisation can materially overstate or understate Maintainable EBITDA and therefore the resulting valuation.
10
Business-quality assessments are judgemental
Factors such as the following require judgement:
- customer retention
- recurring revenue
- competitive position
- owner dependence
- supplier concentration
- operating resilience
- financial information quality
- saleability
Two reasonable users may score the same business differently. The scoring framework is intended to impose consistency on that judgement, not eliminate judgement entirely.
11
Customer concentration
The Customer Concentration Adjustment is an analytical risk adjustment based on the information entered regarding the largest customer and the largest customers collectively. The actual commercial impact may depend on:
- contractual terms
- customer longevity
- switching costs
- termination rights
- market alternatives
- customer relationships
- pipeline strength
- other circumstances
The model adjustment is therefore not a substitute for commercial due diligence.
12
Professional market adjustments
Where the valuation tool permits a Market Conditions Adjustment, this allows the user to reflect circumstances that may not be captured fully by the underlying model, such as unusually strong or weak transaction conditions.
13
Manual assumptions and overrides
Where available, advanced users may replace model-derived assumptions with professional or manual assumptions, including a manual Maintainable EBITDA figure and a Manual Multiple Override.
14
Actual transaction values may differ materially
Transaction price can differ from a ValuBase estimate because of factors such as:
- buyer appetite
- strategic value
- synergies
- competitive bidding
- financing availability
- market conditions
- due diligence
- working capital
- cash and debt
- taxation
- legal issues
- warranties and indemnities
- earn-outs
- deferred consideration
- rollover equity
- seller financing
- management arrangements
- customer or supplier risks
- transaction structure
- negotiation
15
Independent judgement and professional advice
ValuBase is designed to support preliminary analysis and informed discussion. You should exercise your own judgement and obtain appropriate professional advice before making a material transaction, investment, financing, legal, accounting or tax decision.
For circumstances requiring a formal or independently supportable valuation — including tax, litigation, regulatory, financial-reporting or third-party reliance purposes — an appropriately qualified valuation professional should be engaged.
16
Accuracy and availability of the service
We aim to keep ValuBase functioning accurately and reliably, but we do not guarantee that the website will always be uninterrupted, error-free or available. Software can contain errors, and users should independently check outputs where material decisions are involved.
17
Changes and updates
ValuBase may update the methodology, calibration, sector classifications, interfaces, explanatory content, valuation factors and features to improve the service or reflect changes in market evidence.

- brand

- methodology presentation
- software

Users may use valuation outputs for their own legitimate business purposes. Users may not copy or reproduce substantial parts of the application, reverse engineer proprietary methodology beyond what the law permits, scrape calibration data, systematically extract model parameters, resell or commercially reproduce the ValuBase service, or falsely represent ValuBase content as their own.

21
Privacy
Use of the website is also governed by the separate ValuBase Privacy Policy. The Privacy Policy describes how personal information is handled, including that valuation inputs are processed within your browser.
22
Liability
To the extent permitted by applicable law, ValuBase and its operator will not be responsible for losses arising solely from a user’s reliance on an indicative valuation where the user has failed to obtain appropriate independent advice for a material decision.
No monetary liability cap is stated in these Terms; the operator’s liability position has not been separately reviewed and is not asserted here.
23
Statutory rights
Nothing in these Terms is intended to affect any statutory rights that apply to you and cannot lawfully be excluded or restricted.
24
No professional relationship created
Use of ValuBase does not create an adviser-client, accountant-client, solicitor-client, fiduciary, partnership, agency or other professional relationship between the user and ValuBase. ValuBase does not act for a buyer, seller or other transaction party merely because the tool has been used.
25
Governing law
The governing law applicable to these Terms and to use of ValuBase has not been finally confirmed in the current application. This section should be settled by the operator following legal review before any formal reliance is placed on it. Until then, no specific jurisdiction (including the law of England & Wales, Scotland or any other jurisdiction) is asserted here.
Regardless of the governing law agreed, nothing in these Terms is intended to remove mandatory consumer rights a user may have under the laws applicable to them.
26
If part of these Terms is unenforceable
If any provision of these Terms is found to be invalid or unenforceable, the remaining provisions will continue to apply to the extent permitted by law.
27
Changes to these Terms
These Terms may be amended as the service changes. Material changes will be reflected by updating the “Last updated” date on this page. Continuing to use ValuBase after a material change constitutes acceptance of the updated Terms to the extent permitted by law.
