Energy-Efficient Home Systems in Sandton & Northern Johannesburg

Between City Power's 2026 tariff increases and ongoing grid instability, the cheapest electricity is the unit you never have to buy. Apple Plumbing & Electrical helps Northern Johannesburg homeowners lower their monthly power and water bills by treating the home as one integrated system — solar PV, efficient hot water, backup power and smart electrical upgrades working together rather than as disconnected purchases. Led by registered electricians and PIRB-registered plumbers, we design, install and certify energy-efficient systems across Sandton, Midrand, Fourways and Bryanston. Every upgrade is sized to your actual consumption and signed off with the Certificates of Compliance your insurer and future buyer will ask for.

What we do

Our energy-efficiency work spans three connected areas. First, hot water: a conventional geyser is typically 40% of a household electricity bill, so we replace resistive heating with solar geysers, heat pumps or Geyserwise-controlled scheduling to cut that figure by 60–70%. Second, power: we install hybrid solar PV, lithium battery backup and properly separated essential-loads wiring so you generate your own power by day, ride out load-shedding, and avoid the most expensive tariff blocks. Third, protection and efficiency: whole-home surge protection, LED and smart-lighting conversions, and fixing the plumbing faults — hidden leaks, low pressure, short-cycling pumps — that quietly waste electricity. We start with a home energy assessment, reviewing three months of bills and your DB board, then recommend the upgrades with the fastest payback first rather than selling you the biggest system. Everything is installed in-house and certified with valid Electrical and Plumbing Certificates of Compliance.

Why choose Apple Plumbing & Electrical

Most companies sell you one box — a solar kit, a battery, a geyser. We look at the whole home, so the upgrades work together and pay back faster. As a registered electrical contractor with registered electricians and PIRB-registered plumbers in-house, we do the work ourselves and issue the Electrical and Plumbing COCs that keep you insured and sale-ready.
