Whole-Property Energy Assessment
A smarter way to plan your property's energy future.
Modern homes and commercial buildings are becoming increasingly complex. Solar PV, battery storage, heating systems, EV charging, ventilation and electrical demand all interact - and changes to one system can affect the performance of another.
Warm Homes Group is developing a connected, whole‑property approach to energy planning. Instead of looking at technologies in isolation, we analyse how your property uses energy today, how its requirements may change in the future and what should be considered before investing in major improvements.
Understand first. Improve second.
Why look at the whole property?
Energy upgrades are often planned one technology at a time - solar panels, batteries, EV chargers or heating systems. But these decisions are connected, and planning them separately can make it harder to understand the right system size, installation order and how different technologies may interact.
A whole‑property energy assessment helps answer essential questions before you invest:
How much energy does the property use?
When is that energy being used?
What electrical capacity is available?
What systems and technologies are already installed?
What additional demand could be created in the future?
Could improvements work better when planned together?
Which improvements should be prioritised?
Our whole‑property approach brings these considerations together, helping you make better‑informed, future‑ready decisions.
Understand first. Improve second.
WHAT A WHOLE‑PROPERTY ASSESSMENT COULD CONSIDER
Depending on the property, its existing systems and your goals, areas considered may include:
-
Current consumption, usage patterns, peak demand and potential future requirements.
-
Existing electrical supply, capacity, consumer unit, circuits and infrastructure relevant to current and future energy technologies.
-
Roof characteristics, shading, potential generation and considerations around appropriate system design.
-
Existing consumption and generation patterns, potential storage requirements and interaction with electricity tariffs.
-
Existing heating and hot-water systems, energy requirements and how future changes could affect property demand.
-
Current or planned electric vehicle charging requirements and their potential impact on electrical demand.
-
Relevant building characteristics, insulation, ventilation and factors that may influence energy use and comfort.
-
Planned technologies, changing occupancy or usage, electrification and potential future property improvements.
How Is This Different From an EPC?
An Energy Performance Certificate (EPC) provides a standardised assessment of a property’s energy efficiency and is required in certain circumstances.
A whole-property energy assessment serves a different purpose.
It looks more closely at the property when considering technologies and future requirements such as solar PV, battery storage, EV charging, heating, electrical demand and future electrification.
The aim is to provide additional insight before major energy improvements are made.
A whole-property energy assessment does not replace an EPC, electrical inspection or any other statutory assessment or certification where one is required.
Is a Whole-Property Energy Assessment Right for You?
You don't need to know exactly what technology you want before speaking to us.
In fact, that's the point.
It could be useful if:
You're considering solar PV or battery storage but aren't sure what size or setup is right for your property
You expect to add an EV charger or other electrical technology in the future
You're considering changes to your heating or hot water
You want to understand whether your existing electrical infrastructure can support future demand
You're planning several energy improvements and want to understand how they could work together
You're a landlord or property investor planning improvements across one or more properties
You manage housing, commercial buildings or a property portfolio
You want to understand the property before deciding what to buy
If you're asking “What should I install?” - we think the better question starts with
“What does my property actually need?”
Why Warm Homes Group?
We begin with the property - not the product.
Our practical experience spans solar PV, battery storage, electrical installations, heating and cooling across domestic and commercial properties.
Renewable and electrical installation services are delivered through Warm Homes Energy Group Ltd, with applicable industry accreditations and certification.
That practical installation experience gives our whole-property approach an important foundation:
Understanding what happens beyond the report - when technology actually has to work in a real property.
We provide services across North Wales and North West England.
Energy MOT or Whole-Property Energy Assessment?
Already have solar, batteries or other energy technology?
An Energy MOT helps you understand how your existing system is performing and whether there are opportunities to optimise it.
Planning your property's next energy improvements?
A Whole-Property Energy Assessment looks at the bigger picture before you invest.
What you already have → Energy MOT
What your property may need next → Whole-Property Energy Assessment
Your Property. Your Energy. Your Future.
Before deciding what to install, understand what your property actually needs.
Understand first. Improve second.
Accredited. Certified. Trusted.
