Electricity prices in the UK change regularly. Ofgem reviews the price cap every three months, and time-of-use tariffs can change from hour to hour. Nobody can tell you for certain where prices will go next, and we won’t try.

What solar does is change how much of your electricity you have to buy in the first place.

What Solar Changes

Every unit of electricity your panels generate and you use in the house is a unit you don’t buy from the grid. That means:

Less of your bill depends on the unit rate. If prices go up, the electricity you generate yourself isn’t affected.
You get paid for what you export. Through the Smart Export Guarantee (SEG), larger energy suppliers have to offer a tariff for the electricity you send back to the grid from an MCS certified system. The rate is set by the supplier, so it’s worth shopping around.
Your standing charge doesn’t change. You’re still connected to the grid, so you still pay it.

Where a Battery Fits In

Panels generate most in the middle of the day, which is often when people are out. A battery stores that power so you can use it in the evening instead of exporting it.

With a time-of-use tariff, a battery can charge overnight at the cheap rate as well as from your panels. What that’s worth depends on your tariff, your battery size and when you use power, so we work it out for your property at survey.

What Affects Whether It’s Worth It for You

How much electricity you use, and when. Daytime use makes the most of the panels. Evening use is where a battery helps.
Your roof. Orientation, pitch and shading all affect generation.
Your tariff. Some tariffs suit solar and batteries much better than others.
Future plans. An electric car or heat pump will change how much you use.

We look at all of this at survey and give you our honest view. If solar won’t work well for your property, we’ll say so.
