Spread the cost of a voltage optimisation unit from £5,000 to £60,000 with flexible finance options. HP, lease, or refinance, compare rates from 40+ lenders.
Yes, voltage optimisation units 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 £5,000 to £60,000, and most deals are written over 24–60 months with a deposit of around 10–20%. Decisions typically take 24–48 hours. Used machines are financeable too, usually with a shorter term.

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.
| Machine or specification | Guide price | Type |
|---|---|---|
| Single-phase voltage optimisation unit for a small commercial unit (specification class) | £5,000 – £10,000 | Single-Phase VO Unit |
| Three-phase voltage optimisation unit for an office or light industrial site | £12,000 – £25,000 (indicative; UK suppliers include Powerstar, price not independently verified) | Three-Phase VO Unit |
| Larger three-phase unit for a factory or distribution centre (specification class) | £25,000 – £45,000 | Industrial-Scale VO Unit |
| Site-wide voltage optimisation for a multi-building campus (specification class) | £40,000 – £60,000 | Campus-Scale VO System |

Check EligibilityA voltage optimisation unit is wired directly into a building's incoming electrical supply, which means it's often treated as a fixture rather than free-standing plant for capital allowances purposes, similar to a heat pump or EV charge point installed the same way. This can affect both the allowances available and whether an asset lender is comfortable lending against the unit on its own, since it's not something that can be easily unplugged and moved elsewhere. Confirm the correct tax treatment with your accountant based on how the unit is actually installed at your site.
Voltage optimisation units are bought by businesses on sites where the incoming electricity supply runs consistently above the standard nominal voltage, common in parts of the UK network, and by landlords and facilities managers looking to reduce equipment strain and extend the working life of motors, lighting and other electrical plant across a site. Because the unit is wired into the main incoming supply, most buyers finance it as part of a wider electrical or energy efficiency project rather than as a standalone item, and installation needs a qualified electrician working alongside the finance process. Replacement is generally driven by a site's electrical load changing significantly, such as a major refit or expansion, rather than the unit itself wearing out, since these units have no moving parts and typically have a long working life.
