6 Reasons to Switch to Solar in London This Year
If you’ve been thinking about installing solar panels in London, there’s no better time than now. With rising energy costs, improved technology, and generous incentives, more London homeowners and businesses are turning to solar as a reliable, long-term energy solution.
As someone who’s worked closely with both domestic and commercial solar installation projects across Greater London, I’ve seen first-hand the benefits—and savings—that solar power brings. Below, I’ll walk you through six reasons why making the switch to solar in
1. Lower Your Energy Bills – For Good
One of the biggest motivations for installing solar panels in London is to reduce energy bills. With electricity prices rising steadily in the UK over the past decade, solar offers a practical way to cut costs.
In fact, the Energy Saving Trust estimates that a typical London household can save between £400 to £535 per year by installing a standard 4kW solar system. These savings can increase if you pair solar panels with a home battery system.
2. London Is Sunnier Than You Think
A common misconception is that the UK isn’t sunny enough for solar. But here’s the truth: solar panels don’t need blazing sunshine to work effectively—they need daylight.
According to UK Met Office data, London receives around 1,500 hours of sunlight per year, making it one of the sunniest regions in the country. Modern solar technology also works efficiently in cloudy conditions, capturing diffused sunlight.
So even on those overcast London afternoons, your panels are still generating power.
3. Government Incentives Make It More Affordable
The Smart Export Guarantee (SEG) lets you earn money for any unused electricity your panels send back to the National Grid. This scheme replaced the old Feed-in Tariff and ensures you’re paid a fair market rate for your exported energy.
There are also grants and zero VAT on solar panel installation, making the upfront cost much more manageable. If you choose a reputable solar installation London company, they can guide you through all the paperwork and eligibility checks.

4. Increase Your Property Value
Properties with solar panel installation in London are increasingly seen as premium real estate. Energy-efficient homes often attract environmentally conscious buyers and command higher selling prices.
A 2019 study by Zillow found that homes with solar systems sold for 4.1% more on average. In competitive London neighbourhoods, this could equate to tens of thousands in additional value.
Not to mention, EPC (Energy Performance Certificate) ratings improve significantly with solar, which is a huge plus for landlords and homeowners alike.
5. Reduce Your Carbon Footprint
Installing solar panels isn’t just good for your wallet—it’s good for the planet. The average UK home using solar can cut its carbon emissions by up to 1.6 tonnes per year.
For those aiming to live more sustainably or reduce their household’s environmental impact, switching to solar is one of the most impactful changes you can make.
Many of our clients combine solar with other eco-friendly upgrades, such as heat pumps or electric vehicle charging stations, for even bigger environmental gains.
6. Solar Technology Has Never Been Better
Gone are the days of bulky, inefficient panels. Today’s solar systems are sleek, efficient, and often come with warranties of 25 years or more.
Some panels even use half-cell technology, which boosts efficiency and energy production in low-light conditions—ideal for London’s variable weather.
Plus, with the rise of smart inverters and home batteries, it’s easier than ever to track your energy usage and store surplus electricity for later.
What to Look for in a Solar Installer
Choosing the right company for solar panel installation in London is crucial. Look for:
- MCS Certification – Mandatory for SEG eligibility.
- Experience in local planning regulations (especially for listed buildings).
- Transparent pricing and product warranties.
- Strong customer reviews and case studies.
