A site survey, not a standard box
Incoming voltage varies by region and time of day. If it is already close to the equipment rating, optimisation will not pay. We would rather tell you that than install hope.
Voltage optimisation
If the incoming voltage is high, you may be paying to dump heat.
UK sites often receive more voltage than equipment needs. Voltage optimisation sits at the incoming supply and trims that extra, so motors, lighting and kit draw less for the same job. We survey before we recommend it — it is not a fit for every board.
No upfront quote fee. No obligation. Clear next steps before you switch.
Survey first
We measure incoming voltage and load before anyone sizes a unit.
Same kit
Existing equipment, less wasted energy — not a full plant replacement.
With the tariff
Savings sit on top of a decent electricity contract, they do not replace it.
Who it is for
Built around how the sites actually use energy
We match the product to the meters, the load and the contract you already have — not a generic package.
- Industrial and commercial sites with motors, refrigeration, HVAC or older lighting.
- Businesses that have already switched tariff and still want to cut kWh, not just p/kWh.
- Estates where a survey shows consistently high incoming voltage.
- Teams comparing solar and efficiency measures and wanting both modelled.
The range
How we treat it
Options explained in plain English. Pricing is quoted to your sites and term — we do not publish a public rate card.
Fixed reduction vs smarter control
Some systems set a lower voltage; others track the incoming supply. The right choice depends on how much the voltage swings and what the load is.
Alongside procurement
A 8–12% kWh cut (where it is real) is worth more if the remaining units are also on a decent contract. We quote VO and the electricity tariff as a pair when both are in play.
With solar
Optimisation cuts import; solar replaces some of what is left. They are not substitutes. A site can justify both, one, or neither — the survey decides.
Included
What a quote includes
- Logged or sampled voltage and a view of the main loads.
- An honest savings range, not a single guaranteed percentage.
- Install constraints at the incoming position.
- Warranty and maintenance expectations.
- Interaction with the current electricity contract and any planned solar.
Worth knowing
If the voltage is already low, do not fit it
Voltage optimisation is a site-specific efficiency measure. On a low-voltage incoming supply it can harm kit. That is why we survey first and walk away when it is the wrong tool.
In practice
Where it tends to work
A factory on a high incoming voltage
Motors and lighting run hot. A measured reduction cuts kWh without changing how the line operates.
Already on a good tariff
Procurement has done its job. The next saving is using fewer units. VO is one of the options we put next to solar and behavioural change.
A small office on LED and laptops
Often not worth it. We will say no rather than squeeze a unit into a comms cupboard.
Questions
What should I know before I request a quote?
It depends on incoming voltage and the mix of loads. Typical marketing percentages are not a quote. A survey gives a range we are prepared to stand behind.
