Voltage Optimisation Saves Energy & Protects Your Equipment
READ MORESmarter Voltage for Greater Efficiency

Voltage optimisation is a proven way to cut energy use, lower electricity bills, and extend the life of appliances and electrical systems. Many UK buildings receive more voltage than they need—often 240–250 V instead of the optimal 220 V—wasting power and placing extra heat stress on equipment.Forest Electrical designs and installs tailored optimisation systems for homes, commercial spaces and industrial sites, delivering consistent, efficient power where it’s needed.
Is Your Property Using More Electricity Than It Needs To?
A voltage optimiser automatically steps the supply down to the optimal level, preventing over‑supply and reducing wear. Our units include built‑in monitoring so you can track savings in real time and document results for audits or ESG reporting.

- Grid Supplied Voltage
- Optimised Voltage
- Returned Voltage

Who Benefits from Voltage Optimisation?

DOMESTIC
Homes with solar PV, heat pumps or battery storage, where stable voltage supports overall system efficiency and protects equipment.

COMMERCIAL
Commercial sites running HVAC, refrigeration or mission‑critical IT equipment, where voltage swings raise costs and accelerate wear.

PUBLIC & COMMUNITY
Schools, offices and public buildings with extensive lighting and electronics, where consistent savings accrue year after year.
Why It Makes Sense
- Save 12–15% on your electricity bills
- Typical ROI over 25% with 2–3 year payback
- Protect & extend electrical equipment life
- Cut your carbon footprint & improve energy efficiency
- No need to switch energy tariffs
