How Upgrading Your Home’s Electrical System Can Lower Energy Bills
Introduction
With UK energy costs rising and no end in sight, home owners are looking to smarter means of cutting down electricity bills. Changing suppliers or switching off lights is included in the package, but not many see a great opportunity hiding behind the walls—your electrical infrastructure.
In fact, the age, design, and efficiency of your home's electrical infrastructure have a direct impact on your energy consumption and wastage. As will be outlined in this guide, an upgraded system can go a long way towards greater energy efficiency and how OTG Electrical can help you in attaining savings in the long run.
1. Old Wiring = Wasted Energy
Most UK houses—particularly those constructed prior to the 1980s—are still running on outdated wiring. These systems were not planned for today's energy demands and have the propensity to deteriorate as a result of inefficiencies or cannot safely accommodate new appliances.
⚠ Indications of Aging Wiring:
Constantly blown fuses or tripped circuits
Warm or buzzing sockets
Dimming light when appliances are turned on
Rubber or lead-insulated cables
???? How It Affects Your Bills:
The existing cables can heat up unnecessarily, increasing resistance and consuming more electricity than needed.
✅ Solution: Part or complete rewiring with new PVC-insulated cables cuts down energy wastage, enhances performance, and averts safety hazards.
2. New Consumer Units Are More Efficient
Still dealing with an old fuse box? Those older models don't have RCD (Residual Current Device) protection and don't have energy-saving advantages that newer ones do.
✅ Benefits of Changing to a New Consumer Unit: Better circuit protection
Abrupt reaction to surges or faults
Cleaner, more efficient current flow
Smart meter compatibility
SafER Energy Monitoring
We fit smart-ready consumer units at OTG Electrical that monitor usage and assist energy-efficient home technology.
3. Energy-Efficient Lighting = Big Savings
Lighting accounts for approximately 15% of the typical UK household's electricity bill. If you still have halogen or incandescent bulbs in your home, you're spending far more than you need to.
✔ Upgrade Tips:
Change all of the bulbs to LED lights—they utilize as much as 80% less energy and endure 25x longer.
Consider a motion sensor or dimmer in less-used areas
Smart bulbs support scheduled lighting and remote control
We can rewire and enhance your lighting circuits to completely accommodate low-energy or smart lighting systems.
4. Smart Home Integration
A new electrical system enables the incorporation of smart home devices—everything from thermostats and outlets to energy monitors and heating devices.
✅ Benefits: Program appliances to shut off when they are not being used
Control lights, heating, and even plugs with your smartphone
Monitor real energy usage and modify accordingly
OTG Electrical installs smart sockets, thermostats, and home energy monitors that allow you to take charge of your usage—and your bills.
5. Additional Sockets = Less Extension Leads Dependence
A bunch of extension cords? Not only is that cluttered—it's also ineffective.
⚠ Why It Matters:
Extension lead causes voltage drops
They generate heat and consume power inefficiently
Overloaded sockets are a fire hazard
✅ Our Fix: We can install strategically located, power-efficient sockets where you need them, doing away with the necessity of superfluous adapters and allowing you to utilize power more effectively and securely.
6. Balanced Load = Lower Consumption
Older systems often place too much demand on a few circuits, making them work harder and waste more energy.
✅ With a Properly Designed System:
Circuits are distributed evenly
Appliances run more efficiently
You avoid unnecessary energy loss from overheating or overuse
An OTG Electrical inspection includes load balancing analysis to ensure your home uses electricity smarter—not harder.
7. Timed & Zoned Heating Controls
Electric heating systems can be some of the biggest energy drains—especially when left on longer than needed.
✅ Solutions We Offer:
Timer-controlled heated towel rails
Smart thermostats and heating zones
Boost switches for limited-time heating
Underfloor heating with programmable controls
8. Solar-Ready Installations
Thinking of solar panels in the future? A new electrical system means it's easier—and cheaper—to transition when the time comes.
OTG Electrical installs solar-ready consumer units, matching inverters, and smart energy meters which can:
Blend in effortlessly with solar technology
Monitor energy produced vs. consumed.
Optimize your return on investment
Cost vs. Savings: Is It Worth It?
Yes. A power upgrade will save hundreds of pounds a year—and more each year.
Upgrade Estimated Annual Savings
LED Lighting\t£75–£100+
Smart Thermostats£130–£180
Modern Consumer Unit\tUp to 10% system efficiency Full Rewire (30+ year old houses) £200–£300 (plus added safety)
