Methodology you can review

Deeper insight, less friction

In internal user testing, the vast majority of participants found Energicore more in-depth and easier to use than other energy planning tools they had tried. Pages load faster, information is clearer, and forms take less time to complete.

Start in minutes, not weeks

Individuals and organisations can sign up and get started straight away. No waiting for a demo, a sales call, or manual setup from our team.

How our engine works

Built on real data, not guesswork

Official EPC records or RdSAP-aligned predictions, cleaned for clarity, then modelled into a plan you can stand behind.

1. Data in

1

EPC data & predictions

Official Government register data where a certificate exists; RdSAP-aligned estimates where it doesn’t.

2

Clearer, simpler data

Raw records cleaned and normalised into a consistent, jargon-free view of each property.

2. Model & plan

3

RdSAP-aligned modelling

Calculations follow the methodology used in real UK EPC assessments.

4

Measure interaction

Measures modelled together: insulation changes heating load, which affects sizing and savings.

5

Prioritised plan

A sequenced plan with modelled savings, grant flags, and EPC projections.

Savings figures are indicative and based on our RdSAP-aligned model. Actual savings vary by property, occupancy, and fuel prices. See our security & compliance posture.
