Scaling personalised home energy plans with smarter data

Across the UK, organisations are under pressure to help customers and residents cut energy bills, boost comfort and understand their home’s performance. But inconsistent data, low user engagement and complex technical terminology often get in the way.

Here are five ways our Dynamic Engine technology helps organisations deliver accurate, personalised energy advice at scale –  without lengthy questionnaires or costly surveys – and why it could be the key to the success of your engagement programmes.

Dynamic Engine is a high-performance modelling platform designed to deliver fast, accurate, and tailored home energy and retrofit advice at scale.

It fills data gaps and runs thousands of scenarios in seconds, powering a range of Energy Saving Trust tools used by businesses and local authorities to engage customers, residents and internal teams with reliable, personalised recommendations.

A full property dataset can be generated from as few as eight basic inputs. 

Most households aren’t able – or don’t have time – to supply detailed technical information about their homes. Dynamic Engine’s inference module solves this by generating a complete property dataset from as few as eight basic inputs. 

With only an address, it can pre-populate property data by drawing on Home Analytics, our trusted dataset containing more than 90 variables for every property across Great Britain. 

This ensures accuracy while keeping user journeys short, simple and low-effort. 

Setting realistic goals and constraints improves the chance of action.

Users can shape plans generated by our tools based on what matters most – saving money, cutting carbon, or improving EPC performance. They can also set budget limits and input real energy-use data, allowing the model to refine its recommendations further. 

Because pre-made plans are also available, even time-poor users or those unsure about next steps can benefit from great advice.

Real-world behaviours are considered to unlock deeper insights. 

Dynamic Engine goes beyond EPC-level insight. It models electricity demand and solar PV generation at 30-minute intervals, reflecting real-world behaviour across the year. This enables accurate evaluation of: 

• solar PV potential and export 

• heat pump suitability 

• battery storage value 

• EV charging behaviour 

This level of granularity is essential for assessing modern low-carbon technologies and driving awareness of these solutions.

Plus, the more accurate the advice, the more you can educate and engage your users and motivate them to take up any finacial support like loans and grants on offer.

Official standards are applied to ensure customer confidence. 

Our calculation engine is based on the Reduced Data Standard Assessment Procedure (RdSAP), ensuring outputs remain compatible with official standards, but are enhanced with richer datasets and more intelligent assumptions. 

This enables us to deliver more accurate and actionable advice, while still aligning with the official methodology currently used by the government to assess home energy performance. 

Results are delivered fast, so even time-poor users can benefit.

Dynamic Engine runs thousands of simulations per home, rapidly identifying the optimal combination of improvements for each property, budget and motivation.  

Users can still manually adjust their plans, maintaining control and ensuring recommendations are both accurate and practical, but results are still delivered fast. 

One of the tools that uses Dynamic Engine to allow residents to create tailored retrofit plans in Homewise.

Putting users at the centre of energy and retrofit engagement is key to long-term success.

Intuitive, low-effort digital tools that reflect real behaviours, like limited time, varied knowledge and different motivations, drive higher uptake, reduce drop-off and build trust.

By prioritising user experience from the start, organisations deliver better outcomes today while ensuring communication strategies remain scalable, adaptable and future-proof as expectations, technologies and policy landscapes evolve.

If you’re ready to create digital journeys that genuinely motivate residents and customers to act, why not let us show you what’s possible?
