Volt Optimization

Volt Optimization

Chapmans Electrical are your local E-Pro approved Volt Optimization energy saving experts in Birmingham and the West Midlands.

In the UK, the average single phase mains electrical supply voltage is 242 volts. This is quite high compared to other countries. Electrical appliances with the CE mark must be capable of working anywhere between 207 and 253 volts.

Our unusually high voltage in the UK can cause a reduction in the life expectancy of equipment which is really being used above it’s optimum supply voltage. Depending on the type of load on the circuit being supplied, it is also wasteful and substantial direct energy savings can be made through optimising the supply voltage to the equipment being used.  Every site is different but we can advise you on suitability and potential energy savings. Any facility using electrical equipment and lighting should consider voltage optimization to reduce carbon footprint and energy bills.

Chapmans Electrical was established as a family business in 1925 and remains a family run company to this day. Our core values of honesty and integrity, combined with high standards and providing a quality service remain unchanged 90 years later.

We’re based in Cradley Heath in the Black Country, near Birmingham, West Midlands, with an army of engineers and fleet of vans that extends our voltage optimisation service to most of the Birmingham and West Midlands region. Beyond neighbouring Halesowen, Stourbridge, Dudley, Wolverhampton and West Bromwich to cover all areas including Worcester, Shrewsbury, Solihull, Walsall, Sutton Coldfield and further afield.

All of our work is fully guaranteed and insured and all our engineers are fully qualified and certified, properly trained, well equipped and even CRB checked for your peace of mind.

Voltage optimisation is an established technology that manages incoming voltage and reduces it to a level more suitable for the electrical equipment being used. An optimised single phase supply voltage will normally be in the region of 220 volts but there is no one size fits all solution and optimal voltage differs depending on the load being supplied.

Chapmans Electrical will work with you to guide and advise you and recognise your needs. We will perform a site survey in which we take all necessary voltage and current measurements, determine the types of equipment and other factors which need to be taken into account. We will then be able to make all necessary calculations to specify the right voltage optimisation equipment, or choice of voltage optimisation equipment, and suggested configuration which will be tailored specifically for you. We can also predict estimated savings and return on investment.

As E-pro approved energy management professionals of Marshall-Tufflex energy management solutions for single or three phase supplies and with 90 years of experience behind us, you can be assured that we have an in-depth understanding of current energy management technologies and are experts in our field.

Once we have installed the voltage optimisation system you need we can offer maintenance and repair services and also reconfigure the system if your loading requirements significantly alter or you have any other issues.

Call the professionals for your voltage optimisation needs and arrange for a Chapmans engineer to visit you.

What our Customers have to say:


Just had new electric heating installed throughout the house. Really impressed with the professionalism of the team, from the girls on the switchboard, Mark who came to do the survey and prepare the quote, through to Chris and his electricians. Any mess made was cleared up immediately and all the packaging and old equipment removed. Highly impressed from start to finish!
