Your green journey

Don't spend thousands on solar or a battery until you've checked your journey.

We look at your whole home at once, your tariff, your roof, your car, and show you what's actually worth doing, in what order, and what it pays back.

Not sure where to start?

It's not you. It's how it's sold.

And nobody's job is to tell you what to do first.
Four decisions, usually sold by four different people.
01
Sold one piece at a time
Installers sell solar and batteries. Energy companies sell tariffs. Car companies sell cars. Nobody brings them together.
02
Sized to the deal
When pay rises with the size of the system, the push is towards the biggest one.
03
Savings with no timescale
A yearly saving means little until you know how long it takes to earn back.

ESME is the one that tells you what to do first.

We look at your tariff, roof, battery and car together, put the steps in order, and show what each one costs and how long it takes to pay back. One plan for your home, before anyone sells you anything.

The short version

The whole idea in 51 seconds.

Why people start with ESME, and what happens when you do. Sound on.
Why we're different

Most tools look at one thing. We look at the whole picture at once.

Your home
Your tariff
The cheapest hours of the day are worth more than most people realise.
Your energy profile
How much electricity you use, and when, so we can match you with the right tariff.
Your roof
We measure it from above, so you don't have to guess how many panels fit.
Your battery
Stored cheap power you use in the evening, when everyone else is paying peak.
Your car
An electric car changes the maths more than almost anything else.
Your budget
If the best option costs more than you want to spend, we say so.
How we make money
If you ask for quotes, the installers we pass your details to pay us for that introduction. If you switch tariff through us, the supplier pays us a commission. You never pay us anything, and we'll always tell you who pays us.
Read the full version
What we won't do
We won't pass your details to anyone unless you tick the box, and then only to the installers we name. We won't push a product at you, and we won't tell you to buy a battery if your money is better spent elsewhere. Sometimes the answer is just change your tariff.
Advice whatever you decide
If the best move is to change your tariff, or to wait, that's what we'll tell you. The plan is yours to keep, whoever you use.
Tariffs

The best tariff changes with what's in your home.

A tariff that suits you today can be the wrong one after a battery, solar panels or an electric car. So we choose it for the home you'll have, and tell you when it's time to switch.
Example
The tariff that wins at each stage.
Today
A standard fixed rate
Add a battery
A cheap overnight rate
Add an electric car
An EV overnight rate
Payback, not just savings

A saving only matters next to what it costs.

Two options can save similar amounts a year and take very different times to pay back. We show cost, saving and payback together for every option.
Indicative only, not financial advice.
Example
Years to pay back
EV tariff and a battery
Costs £6,800, saves £1,690 a year
4.0 years
Tariff, solar and a battery
Costs £11,400, saves £1,860 a year
6.1 years

When you're ready to buy

Quotes you can check against your own numbers.

No inflated prices and no guesswork. Because you already know what your house needs and what it will return, you can tell a fair quote from a padded one before you sign anything.

Higher, ask why
01
Know what you need before anyone quotes.
Your journey sets the spec, so every installer quotes for the same job.
02
Spot an inflated price straight away.
Each quote sits next to the cost and payback we worked out for your house.
03
Only if you tick the box.
Your details go to the installers we name for your area, and to no one else.
04
Local installers we have vetted.
Checked for the certificates and the track record before they quote for anyone.
A plan, not a shopping list

You don't have to do it all at once.

We put the steps in order: what to do now, what to do next, and what to leave until something changes, like the boiler going or the roof needing work.
Example
Now

Change your tariff

Costs nothing. Worth doing whatever else you decide.
Next

Add a battery

When you're ready. It stays in your plan.
Later

Add solar panels

When the roof needs work, so it's only done once.
Before you buy anything

Five mistakes worth avoiding.

Free advice, whether you use us or not. Take these questions to anyone who quotes you.
  • 1
    Buying the biggest system you're offered.
    Ask instead. Ask what a smaller one would pay back.
  • 2
    Getting quotes before you know what you need.
    Ask instead. Get your numbers first, so you can tell a fair price from an inflated one.
  • 3
    Choosing a tariff before your kit is in.
    Ask instead. Ask what the best tariff will be afterwards.
  • 4
    Putting solar on a roof that needs work soon.
    Ask instead. Ask whether to fix the roof first.
  • 5
    Sizing a battery without thinking about a car.
    Ask instead. Ask what changes if you go electric.
