Every month you buy power you could be making on your own roof. Solar makes it, a battery saves it for the evening, and a heat pump turns it into warmth. That's the whole idea.
Pick one, or combine them for the biggest savings. Every system is designed around your home.
High-efficiency panels sized for your roof, so you run your home on your own electricity through the day and sell the extra back to the grid.
Store what your panels make in the day and use it at night, instead of buying electricity back from the grid at peak prices.
Swap your gas, oil or LPG boiler for low-carbon heating that warms your home and your hot water all year round.
Move the slider to match your monthly electricity bill.

Your energy supplier pays you for spare electricity you send back to the grid.
From the first survey to switch-on, everything was explained clearly and nobody pushed us into anything. The panels and battery went in over two days and the team left the place spotless. Our bills have already dropped.
We were nervous about replacing our old gas boiler, but OESL sorted the grant and talked us through every step. The house is warmer than it's ever been and the heat pump is surprisingly quiet.
I got three quotes and OESL were the clearest by far, with no hidden extras. The install was tidy, and I love checking the app to see what the roof is making each day.
Yes. Panels run on daylight, not heat, so they still generate on cloudy days. Output is highest from spring to early autumn.
It depends on your roof, the size of the system and whether you add a battery. After a free home survey we give you a clear, itemised quote.
Most rooftop solar on houses in England counts as permitted development, so usually not. Listed buildings, conservation areas and flat roofs can be different, and we check this for you.
Most solar and battery installs take 1 to 2 days. Heat pumps usually take a few days, depending on your current heating system.
Yes. With an MCS certified install you can sign up to the Smart Export Guarantee and your energy supplier pays you for the power you send to the grid.
Most homeowners in England and Wales replacing a fossil fuel boiler can get £7,500 through the Boiler Upgrade Scheme, or £9,000 for oil and LPG homes until 31 March 2027. We apply on your behalf and take it off your invoice.
Most panels last 25 years or more, and quality panels come with long performance warranties.
