When a Budget is released, the headlines usually fly by so fast that it’s hard to understand what any of it means for you. There’s always a lot of noise, especially around the Big Headlines, such as energy bills, support schemes, and the wider push towards cleaner power.

If you’re thinking about installing solar panels or adding a battery to your home, last week’s Autumn Budget contained a few changes worth knowing about. Nothing dramatic, nothing that forces your hand, but enough to shape the way you think about the long-term cost of running your home.

Electricity bills are set to fall from April 2026

The government has decided to take two long-standing policy costs off your electricity bill and fund them through taxation instead. These are the Energy Company Obligation (ECO) and most of the domestic part of the Renewables Obligation (RO). You don’t need to know the inner workings of either scheme, but it is important to understand the potential impact on homeowners.

From April 2026, the average household should see roughly £134–£154 taken off their annual energy bill. That number is the estimate put forward by government and energy analysts. Essentially, households that use more electricity than average, such as homes with heat pumps or storage heaters, could see even higher savings.

So, from April 2026, your electricity will cost a little bit less than it does now.

No new grants for solar panels

There were no new grants or incentives for homeowners in this Autumn Budget for rooftop solar panel installations, with or without batteries for energy storage.

As a homeowner, however, your decision on whether to install solar panels for your home still depends on:

• The upfront price from your chosen installer
• How much electricity your home uses
• Your home’s capacity for solar generation
• Your access to Smart Export Guarantee tariffs
• The existing 0% VAT on solar and domestic batteries

The good news is that while the Chancellor’s latest budget hasn’t added anything new in terms of grants or funding for domestic solar installations, it does maintain the current solar installation incentives.

ECO is ending, and the wider retrofit landscape is adjusting

The Energy Company Obligation (ECO), which has existed in various forms for more than a decade, is removed from energy bills from March 2026. ECO has mainly supported insulation and heating upgrades in low-income households, so while this change isn’t directly about solar, it’s still relevant to some homeowners.

The removal of the existing contribution to the ECO scheme from domestic energy bills, does create a gap that the government intends to fill through the Warm Homes: Local Grant funding. This new approach includes additional funding and could eventually support a range of home upgrades.

Some local and national schemes linked the Warm Homes programme of funding already allow solar panels and battery storage where the household meets eligibility rules. But the details of how the wider Warm Homes scheme will run haven’t yet been fully published, and the transition from ECO to the new model will take time.

You really don’t need to become an expert in retrofit funding to understand what this means. Installer capacity, supply chains and confidence across the energy-upgrade sector all rely on stability. Any change as big as the end of ECO creates uncertainty until the new approach beds in.

It certainly doesn’t stop you installing solar, but it’s part of the wider energy efficiency picture in the UK.

0% VAT on solar panels and batteries is still in place

The Budget left VAT relief on solar panel installations unchanged, so the 0% VAT relief for home solar panels and battery systems is still in place until the end of March 2027.

This tax change, introduced in recent years, is still one of the most significant financial benefits for homeowners. It keeps the upfront cost lower and makes solar more achievable for a wider range of households. You don’t need to apply for anything or meet any special criteria. It’s automatic when you use a VAT-registered installer.

No changes to export tariffs or planning rules

When you work with an MCS accredited solar installer and you’ve registered with your energy supplier, you’ll continue to receive payments for the surplus electricity you export back to the grid under the Smart Export Guarantee (SEG).

This Autumn Budget did not make any changes to the Smart Export Guarantee (SEG), and each energy supplier still sets their own tariff rate. Planning rules for rooftop solar on most homes remain the same too.

In practical terms, you can still access the SEG programme via your energy supplier, and benefit from significantly reduced energy consumption and associated costs.

How lower electricity prices affect solar savings

Domesitc solar panels, especially with battery storage, save you money in two ways:

• By cutting down the electricity you’d normally buy from your supplier
• By earning you payments for any extra power you export under the Smart Export Guarantee (SEG)

When electricity prices drop, the savings from avoiding those costs shrink a little. For most homeowners, the difference is small and barely noticeable once you look at your actual usage and generation.

Here’s what hasn’t changed:

• Daytime electricity rates are still high, so generating your own power during the day saves you more.
• Standing charges keep rising, which solar can’t eliminate, but they make reducing your usage even more valuable.
• Export tariffs still pay you for every unit you send back to the grid.
• Adding a battery boosts your return, because you can store solar energy and use it later instead of buying from the grid.

So, the bottom line is that solar energy is still a strong long-term choice for sustainability and lower energy bills, especially if you use a lot of electricity during the day or plan to pair your panels with a home battery.

Some households will gain more from solar than others after the Budget

The Chancellor’s Autumn Budget doesn’t change the basic profile of who benefits most from solar:

• High-electricity households
  Homes with EVs, electric heating, or day-time appliances continue to see meaningful savings. They also gain from the reduction in electricity bills, so their overall running costs fall further.
• Homes already using a lot of electricity in the evening
  A battery can make a big difference by shifting solar energy into the times you need it most.
• Lower-usage homes
  Solar still brings value, but the financial return relies more on long-term planning, export rates, and personal preference.

The Budget makes minor adjustments without altering the core beneficiary groups.

Why now is a great time to go solar

You’re in a better position today than you’ve been for quite a while. The 0% VAT relief remains in place, installation prices have settled after several years of volatility, and the wider energy market is more predictable than it has been in a long time. That gives you a solid foundation for making a confident decision.

Solar technology has moved on too. Panels are more efficient, batteries offer better storage capacity, and export tariffs continue to reward every unit of clean energy you send back to the grid. You’re working with mature, proven technology rather than early-stage innovation, which keeps both performance and running costs steady.

The Budget didn’t introduce time-limited grants that would make waiting worthwhile, and there’s no sign of a large national incentive arriving soon. What you do have is a combination of stable pricing, clear policy, and a long-term reduction in electricity costs. Taken together, it creates a sensible moment to move forward, especially if your home uses a decent amount of electricity or you plan to add a battery.

When the figures already look good for your household

A simple wrap-up

So, here are the highlights from the Autumn Budget in terms of solar panels for homes:

• Your electricity bill should fall by £134–£154 a year from April 2026.
• No new grants or funding specifically for solar or batteries.
• 0% VAT on solar and domestic storage is unchanged.
• Export tariffs and planning rules remain the same.
• ECO is ending, and the Warm Homes Plan will replace parts of it, but that shift won’t affect most solar buyers.
• Solar remains a strong long-term option for many homes, especially those with higher usage or plans to add a battery.

In short, this Budget changes the background economics of energy, not the fundamentals of buying solar. Your decision rests on your home, your usage, and your plans – get in touch with us today to discuss your requirements and to get a FREE quote on a solar installation for your home.
