Independent advisory · Domestic & commercial
Know the next 25 years before you spend the next £20,000.
Most homeowners commit tens of thousands to energy without ever testing whether it is the right decision. We are the advisers who check first — independently, in writing, and plainly either way.
Free eligibility review · £195 assessment fee, refunded in full if we can't improve your position · No obligation, ever

Our standing
The reference point for household energy and heating advice
Energy Wise was established to bring the discipline of professional advisory — the standard expected of a surveyor, an accountant or a mortgage adviser — to a market shaped almost entirely by installers and salespeople.
We hold no obligation to any manufacturer and no incentive to recommend works a property doesn't need. Every projection is independently verified. Every recommendation is written down, with its assumptions shown, so it can be challenged.

Why it matters
A diagnosis, in a market full of prescriptions
A doctor diagnoses before prescribing. A mortgage adviser assesses suitability before recommending. Energy deserves the same discipline — and almost never receives it.
Doing nothing is still a decision. The assessment tells you whether it's the right one.
What property owners tell us
- “Every company tells me something different.”
- “I can't tell whether my current position makes financial sense.”
- “I don't know if the savings projections are realistic.”
- “I don't want to back the wrong technology — or the wrong company.”
- “I don't have months to spend researching and comparing.”
- “I don't know what I should actually do next.”

Guarantees
Very little risk, entirely by design
Three written commitments that carry the risk on our side of the table.
Suitability Guarantee
We don't invite every household to book. If Smart Energy won't create a genuine long-term advantage for you, we say so — before you spend anything.
No-Pressure Guarantee
The assessment exists to create clarity, not to close a sale. You are under no obligation to proceed with any recommendation we make.
Fee-Back Guarantee
If we can't demonstrate a solution that leaves you in a stronger long-term financial and energy position, the fee is refunded in full.
Commercial advisory
The same discipline, at building scale
For commercial owners and operators, energy is a controllable operating cost hiding in plain sight. We profile consumption, tariff exposure, generation and storage potential, and electrification readiness — then model the financial case honestly.
- Consumption & load profiling
- Tariff and price-risk exposure
- Generation & storage feasibility
- Fleet electrification planning
- Transparent financial modelling
- Procurement & delivery oversight
Before you book
The honest answers, before you spend anything
Invitation only
Not every property qualifies
We review energy usage, financial suitability and technical suitability before inviting a household to book. Homes that can't meet ecovia's minimum performance standards aren't invited — and are told exactly why.
Free and without obligation. Within two working days we'll tell you whether an assessment is worth your time — including when it isn't.
