The challenge

Portfolio decarbonisation is more than just a technical problem

Fragmented portfolio data

Building, energy, condition, compliance and financial data sit in different systems, owned by different teams.

Weak investment evidence

Carbon plans often lack the financial evidence needed for board or lender approval.

A gap between strategy and delivery

Recommendations don't always become invested, phased and trackable programmes.

Quantaco connects technical, carbon, financial and delivery decisions in one platform.

Frequently asked questions

+What is portfolio retrofit decision-making?

Prioritising which buildings to upgrade first, and with which measures, based on carbon impact, cost and risk — rather than treating every asset the same.

+How is Quantaco different from an ESG reporting platform?

Reporting platforms measure and disclose performance. Quantaco sits upstream: it analyses buildings, builds the investment case, and helps deliver the programme that produces the numbers you report.

+What information is needed to analyse a portfolio?

At minimum, addresses, floor areas and use types, energy bills, EPCs and condition surveys sharpen the analysis further, but Quantaco can start from public and modelled data alone.

+Can Quantaco support public-sector estates after the closure of PSDS?

Yes. Quantaco's financial modelling is built to stand up business cases without relying on any single grant scheme, including after the Public Sector Decarbonisation Scheme.

+Can consultants use Quantaco for multiple clients?

Yes. Consultants can run multiple client portfolios from one account, with each client's data and outputs kept separate.

+How are predicted savings verified?

Against metered energy data after delivery, using the same methodology used to model them — so the verified number can be compared directly against the original business case.
