Why Renewable Energy Matters More Than Ever for Homes and Businesses in the South East

Rising global tensions often translate directly into rising energy costs, but recent analysis shows something important: the UK’s growing investment in renewable energy is actively shielding households and businesses from more volatile gas prices.

At SolarTherm UK, we’re seeing this shift play out in real time across the South East – where more property owners are turning to solar PV and battery storage to reduce reliance on the grid.

£7 Million Saved Per Day – Here’s What It Means

Recent industry analysis has revealed that Britain has been saving approximately £7 million per day during the latest Middle East conflict. This isn’t theoretical – it’s a result of a structural shift in how electricity is generated.

Instead of relying heavily on imported gas (which is vulnerable to geopolitical disruption), the UK is increasingly powered by solar PV systems, onshore and offshore wind and locally generated renewable electricity. This transition reduces exposure to global fuel price spikes – and that directly impacts what consumers pay.

What’s Driving These Savings?

The key factor is rapid renewable energy deployment over the past few years. Since 2021, the UK has significantly expanded its clean energy infrastructure:

  • Over 15GW of combined solar and wind capacity added
  • Nearly 28% of total renewable capacity installed in just a few years
  • Solar leading deployment, accounting for the majority of new projects

This acceleration followed the 2021 energy crisis, prompting both government and private sector investment into energy independence.

For homeowners and businesses in the South East, this national trend mirrors what we’re seeing locally – greater demand for solar installations as energy users seek control over their costs.

Solar and Wind Now Power a Large Share of the UK

The impact of renewables is no longer marginal – it’s central. Since the recent escalation in global conflict solar and wind have supplied around 40% of UK electricity demand. Gas has dropped to roughly 23% of the energy mix, with renewable generation increasing by over 50% compared to 2021 levels. This is a fundamental shift in the UK energy landscape.

The Real Cost of Gas vs Renewable Energy

Gas prices remain highly volatile. In a matter of weeks during the recent crisis electricity generated from gas nearly doubled in cost, with prices surging from around £53 per MWh to over £100 per MWh.

Without the increased contribution from renewables, the UK would have faced significantly higher import costs – adding millions per day to national energy spending. For end users, that would translate into higher bills and less predictable pricing.

What This Means for Solar Owners in the South East

For existing solar customers, this is validation. Your system isn’t just reducing your bill – it’s protecting you from sudden price spikes, grid instability and long term energy inflation. With battery storage, the benefits increase further by allowing you to storage surplus energy and using it during peak pricing windows, reducing grid reliance even further. Every unit of your own self-generated electricity you use is one less you buy from expensive suppliers.

Why More Property Owners Are Switching to Solar

For those considering solar, the case is becoming increasingly compelling. Key advantages include:

Energy independence – generate your own electricity and reduce reliance on imported fuels.

Cost control – avoid unpredictable tariff increases tied to global gas markets.

Long term ROI – solar systems typically deliver strong returns over their lifespan, especially with rising grid prices.

Increased property value – energy efficient homes and commercial properties are becoming increasingly more attractive to buyers and tenants and can result in up to a 14% uplift on value.

FAQs

Is solar still worth it in the UK with changing energy prices?

Yes. In fact, rising and volatile energy prices make solar more valuable, as it reduces your dependence on the grid.

How much can I save with solar panels?

Savings vary depending on system size and usage, but many South East homeowners see significant reductions in electricity bills—especially when paired with battery storage.

Do solar panels work well in the UK climate?

Absolutely. Modern solar panels are highly efficient even in cloudy conditions and generate electricity year-round.

Should I add a battery to my solar system?

In most cases, yes. Battery storage allows you to maximise self-consumption and reduce reliance on peak-rate electricity.

How long does a solar installation take?

Most residential installations are completed within 1–2 days, with minimal disruption.
