Why now

Your Bill Climbs Every Evening. And You Generate None Of It.

Right now, every unit of power your home uses comes from the grid.

You pay the most in the evening.

Oven on. Kettle going. Lights, TV, washing machine, devices charging.

That's when a home draws the most... and it's also when grid electricity costs the most.

You have no buffer.

You buy every unit at the price the grid sets, on the day it sets it.

And the price cap is set to rise again on July 1st.

(Then again in October.)

If it goes up, every evening costs more than it does today... and there's nothing on your side of the meter to soften it.

That's the gap a solar and battery system closes.

Daytime

  • Your roof generates power
  • Your home uses some
  • The battery stores the rest

Evening

  • Dinner on, lights on, devices charging
  • Your home runs on stored power
  • You buy far less from the grid at peak price

The system logic

Generate It By Day. Store It. Spend It When The Grid Is Most Expensive.

Your panels make power while the sun is up.

Your battery holds it.

In the evening, when usage spikes and grid prices are highest... your home runs on power you already made.

Less reliance on the grid.

Lower evening bills.

A buffer against future price rises instead of full exposure to them.

If you're on a time-of-use tariff, the battery can also charge overnight at the cheap rate... and run your home through the expensive daytime hours.

Performance Guarantee

Your Year-One Saving. In Writing. Backed By Our Guarantee.

£1,032

Last year our customers saved an average of £1,032 in year one.

Protected.

If your system doesn't hit the written year-one forecast, we pay you the difference.

Most solar companies hand you an estimate and hope it lands.

Before you commit anything, we give you a personalised year-one savings forecast based on your roof, your usage, your tariff and your battery setup.

Not an industry average.

Your number.

Last year our customers saved an average of £1,032 in year one.

Yours may be higher or lower.

The survey is what tells you... which is why we do it first.

If your system doesn't hit the written year-one forecast, we pay you the difference.

That's the Performance Guarantee.

The saving isn't a hope on this page.

It's a number you see before you decide... with money standing behind it.

Why The Price Is This Low

We normally install on SolaX and Fox hardware.

For this campaign we negotiated a one-off bulk purchase on SAJ solar and battery systems.

SAJ is an established manufacturer with certified equipment used across multiple markets.

The lower price comes from how we bought... in a single fixed block.

Not from cutting corners.

Not from skipping paperwork.

Not from using unqualified installers.

We bought exactly 90 complete systems.

Once they're reserved, this campaign price ends.

There's no plan to restock at this cost.

Review your forecast.

You see your projected year-one saving and estimated payback period in writing.

Step 3

Reserve your system.

If the numbers work, a £99 deposit holds your system at £7,999.

If your property isn't suitable... or you see the forecast and decide not to move forward... you get the £99 back.

Step 4

We handle the rest.

Installation, paperwork, grid connection, sign-off.

Suitability

We'll Tell You If Solar Doesn't Make Sense For Your Home

Not every home is right for solar.

Your roof, usage, tariff and expected saving all matter.

If your property isn't suitable, we tell you.

If the numbers don't stack up, we tell you.

We're not here to put a system on a home that shouldn't have one.

If the numbers don't stack up, we tell you.

FAQ

Clear Answers Before You Book

The key checks before booking your free survey, visible without opening anything.

Is £7,999 the full installed price?

For qualifying homes, yes. If extra work is needed, we show you the cost before you decide.

Can I get this installed before the price cap change?

If you book your survey this week we can fast-track qualifying homes. Install dates depend on property suitability, paperwork and availability.

Do I need to switch energy suppliers?

No. You can stay with your current supplier. Some homes save more on a time-of-use tariff.

What if my roof isn't south-facing?

That doesn't automatically rule you out. The survey shows what your roof can produce.

What happens if my property isn't suitable?

We tell you during the survey. And you get your £99 deposit back.

Is SAJ a cheap brand?

No. SAJ is an established solar and battery manufacturer with certified equipment used across multiple markets. The price comes from how we bought, not from the hardware grade.

How long does installation take?

Most installs take 1 to 2 days once scheduled.

What if I don't save what you forecast?

If your system doesn't hit the written year-one forecast, we pay you the difference. That's the Performance Guarantee.
