BEMS Costing Tool™

A Licensed Excel Framework for Practical, Reliable BMS Pricing


The BEMS Costing Tool™ is a purpose-built Excel workbook created by BEMS Cost Assurance to help industry professionals price Building Management Systems in a way that is sensible, transparent and defensible.


This isn’t a generic spreadsheet or downloadable template.

It’s a structured, logical building block for commercial BMS estimating that reflects real-world project requirements.


With the tool you can create cost plans that are:

  • Clearly structured and easy to follow
  • Built on transparent assumptions
  • Ready to present with confidence
  • Defensible under commercial scrutiny


The workbook is distributed under a formal licence, ensuring version control and consistent methodology across users.

“Since adopting the BEMS Costing Tool, our estimating process has become more structured. It has allowed us to dramatically reduce internal discrepancies between estimators. We now approach pricing with a level of confidence and transparency that simply wasn’t possible before.”

Who It Is For

The BEMS Costing Tool™ is designed for use by specialist BEMS contractors in mind. Use it to sharpen bid pricing, maintain margin discipline and ensure consistency across tenders.

What’s Inside the Tool

Inside the workbook you’ll find structured pricing logic covering:

  • IO point classification and controller allocation
  • Hardware build-ups (including panels and network elements)
  • Field device and integration allowances
  • Software, graphics and commissioning cost layers
  • Labour build-ups with practical productivity adjustments
  • Risk and contingency overlays
  • Summary outputs that are easy to communicate


Every part of the calculation is visible and editable, making assumptions open and traceable.

Benefits at a Glance


Consistency

Remove guesswork and apply a repeatable logic across all projects.


Defensibility

Build estimates that you can justify in commercial discussions or audits.


Efficiency

Cut down on repetitive spreadsheet work without losing control.


Clarity

Make every assumption clear — no hidden mark-ups or unexplained figures.


Governance Support

Operate within a structure that aligns with industry expectations for independence and transparency.

Licensing Structure


The workbook is licensed, not sold.


Each licence includes:

  • A controlled digital copy with a unique licence key
  • Named user options
  • Version updates and notifications
  • Access under our usage agreement


Licences are issued on an annual basis with renewal options.


The workbook may not be redistributed, reverse-engineered, or modified beyond permitted configuration parameters.

Independence & Ethical Use


We licence the tool to a range of specialist BEMS contractors.


To preserve the integrity of our independent services:

  • Project data is never shared between licence holders
  • Cross-client benchmarking information is anonymised
  • Conflict management procedures are applied where needed


This ensures that the tool remains a reliable commercial standard rather than a competitive advantage in any one organisation’s favour.

Getting Started


New licence holders receive:

  • A structured onboarding session to get set up
  • Practical configuration guidance
  • Best-practice usage tips
  • Optional governance alignment support


Additional support packages are available for organisations embedding the tool into formal estimating processes.

Why License Rather than Build Your Own?


Most internal spreadsheets struggle with:

  • Hidden assumptions that aren’t visible to reviewers
  • Inconsistent labour build-ups between estimators
  • Lack of a structured controller pricing logic


The BEMS Costing Tool™ has been shaped by real commercial experience — it’s not theoretical, and it’s been tested on live projects.

Built-In Alignment with the BEMSCA Transparency Mark™


One big advantage of using the BEMS Costing Tool™ pricing approach will already align with the expectations of the BEMSCA Transparency Mark™ accreditation scheme.


The accreditation looks for:

  • Consistent and repeatable methodology
  • Transparent cost build-ups
  • Traceable assumptions
  • Clear governance practices


With this tool, much of that groundwork is already in place — making accreditation easier and more straightforward.

Pricing


Licensing is structured based on the number of users, as follows:

Annual Turnover

Year 1 Fee

Up to 3 Users

From £1,999

3 Users

From £1,999

Estimating time is not inexpensive, especially when salary, overheads, and risk exposure are all considered. On top of this, a single misjudged controller selection, labour allowance, or missing gateway, can erode margin far beyond the estimating cost.


The efficiency gains alone can significantly offset the cost of an annual license. The improvements in quality of your tender submissions and reduction of margin leakage will justify the investment many times over.

Optional Services


The following may be requested where required:

  • Implementation & Calibration Workshop
  • Governance Alignment Review
  • Bespoke Configuration / Custom Modules


These services are optional and charged separately.
