If you’ve been wondering, “Is it worth getting solar panels in the UK in 2025?” — you’re not alone. With over 1.73 million UK homes now running on solar, and more being added every day, it’s clear we’ve reached a tipping point.

This blog answers some of the most common questions UK homeowners have about solar panels — from installation to costs — and explains how Platinum Electrical Solutions, backed by trusted supplier Platinum RS, is leading the charge for domestic and commercial solar in the South East and beyond.

How many homes in the UK have solar panels in 2025?

As of March 2025, there are over 1.73 million residential solar installations across the UK, contributing to a national solar capacity of more than 18GW. According to Solar Power Portal, 73% of all new installations in February 2025 were on homes.

This reflects a growing trend: UK homeowners want to cut bills, gain energy independence, and do their part for the environment.

What are the financial benefits of installing solar panels?

One of the most Googled phrases right now is: “Do solar panels really save money in the UK?”
The answer is yes — especially in 2025.

Here’s how UK homeowners are saving:

• Lower energy bills: Home solar systems can cut bills by 50–70% annually.

• Smart Export Guarantee (SEG): Sell your unused energy back to the grid and earn a passive income.

• Long lifespan: Panels typically last 25–30 years, offering excellent return on investment.

With energy prices continuing to fluctuate, locking in your own power source is one of the smartest financial moves homeowners can make.

Are new homes in the UK being built with solar panels?

Yes — and in increasing numbers. In Q4 of 2024, 42% of new homes in England included solar panels, up from just 13% the year before (The Times).

This is due to:

• Stricter energy efficiency regulations

• Eco-conscious buyers demanding greener homes

• Lower installation costs and better tech

If you’re planning a self-build or working on a residential development, installing solar from day one is a smart move — for resale, sustainability, and energy performance.

🔋 What is the best solar panel system for UK homes in 2025?

While there’s no one-size-fits-all answer, a typical UK home in 2025 can benefit from:

• A 3.5–5kW solar PV system

• A hybrid inverter that connects solar to battery and grid

• A 10–15kWh battery to store surplus energy overnight

Platinum’s team can recommend the best system based on your roof space, energy use, and budget — with all products supplied by Platinum RS, so there’s no middleman or guesswork involved.
