Voltage Optimisation Finance

Finance voltage optimisation equipment from £2,000 to £100,000, for sites wanting to reduce electricity consumption and protect equipment. HP, lease, or refinance, compare rates from 40+ lenders.

Can you finance a voltage optimisation?

Yes, voltage optimisations are financed as a standard asset purchase, usually on hire purchase or a lease, with the machine itself acting as the security. UK prices typically run £2,000 to £100,000, and most deals are written over 12–60 months with a deposit of around 10–20%. Decisions typically take 24–48 hours. Used machines are financeable too, usually with a shorter term.

What buyers actually specify

Guide prices for sizing a finance agreement, not quotes. Manufacturers in this market mostly price on application, so where a current UK list price could not be confirmed the row describes a specification class rather than naming a model. Your supplier quote is what the agreement is written against.

Tax benefits

Voltage optimisation equipment generally qualifies as plant and machinery for capital allowances, so a business can typically set some or all of the cost against taxable profits through the Annual Investment Allowance or other first-year reliefs, subject to your total qualifying spend for the year. Confirm current treatment with your accountant before finalising the finance structure.

Market context

Voltage optimisation reduces the incoming electricity supply voltage to closer to the level equipment is actually designed for, which for many UK sites is somewhat lower than the nominal supply voltage. The typical buyer has equipment that runs more efficiently, or lasts longer, at a slightly reduced voltage, and wants both an energy saving and reduced wear on motors, lighting and other electrical equipment. Because supply voltage and equipment mix vary by site, actual savings should be assessed through a site survey rather than assumed from a headline percentage, and most suppliers offer this as part of the initial quote.

Bad credit?

Several of our 200+ lenders specialise in businesses with imperfect credit histories. You may need a larger deposit or personal guarantee, but options exist. Checking your options here does not affect your credit score, because we do not run a credit search to match you. A lender will run their own checks only if you decide to apply.

Frequently asked questions

What does a voltage optimiser actually do?
It sits between the incoming electricity supply and your building's electrical distribution, reducing the voltage delivered to equipment to a level closer to what it's actually designed to run at, since UK supply voltage is often somewhat higher than the nominal design voltage of much electrical equipment. This can reduce energy consumption on voltage-sensitive loads like lighting and motors, and may also reduce wear and extend equipment life, though the effect varies by site and equipment mix.
How much energy saving can I expect?
This depends on your site's actual supply voltage, the mix of equipment you run, and how voltage-sensitive that equipment is, so it varies considerably between sites and shouldn't be assumed from a generic percentage. A reputable supplier will normally carry out a site survey, sometimes including voltage logging over a period of days, before quoting an expected saving, and it's worth basing your finance decision on that site-specific assessment rather than a general figure.
Is voltage optimisation suitable for every business?
It suits sites with a meaningful electricity spend and equipment that benefits from voltage reduction, such as lighting, motors and refrigeration, more than sites dominated by modern switch-mode electronics that are largely insensitive to small voltage changes. A site survey will confirm whether your specific equipment mix and supply voltage make the investment worthwhile before you commit to finance. It's a relatively low-cost, low-risk technology to trial, so even where the survey suggests a modest saving, some businesses still proceed given the equipment's long working life and minimal ongoing maintenance requirements.
What deposit is needed for voltage optimisation finance?
For hire purchase, most lenders ask for 10–20% deposit. Finance leases and operating leases often require no deposit, and because this is a well-established, lower-cost equipment category, some lenders offer close to 100% finance, particularly for smaller SME-scale installations backed by a clear supplier survey and quote. The exact figure a lender offers often reflects your trading history and credit profile as much as the equipment itself, so a strong set of accounts can sometimes bring it down further, and it's worth comparing terms from more than one lender rather than accepting the first quote.
How quickly can I get voltage optimisation finance?
Most applications are approved within 24 to 48 hours once accounts and a supplier quote are provided. For deals under roughly £20,000, same-day approval is common, and installation itself is usually completed within a day or two once the unit is on site, given it's typically fitted at the incoming supply point without major building works. Providing a full set of recent accounts and a firm, itemised supplier quote at application stage generally speeds up the underwriting process, since most delays come from lenders chasing missing paperwork rather than from the credit decision itself.
