Ready to make the switch to renewable energy?
We’ll guide you from your first survey through to powering your home with clean, homegrown energy. Our installation process is simple:

  • Pre-installation survey & structural assessment
    An Engineer conducts a property, roof and/or electrical survey and provides a tailored design for your home, whether that's solar, battery storage or a heat pump.
  • DNO approval (where applicable)
    For solar and battery systems, we'll acquire DNO approval: G99 pre-installation (up to 45 working days) and G98 post-installation.
  • Site preparation
    Scaffolding or other access equipment is arranged where needed to ensure a safe, efficient installation.
  • Installation and commissioning
    We'll install your system - solar panels, battery, or heat pump - then test everything and set up monitoring.
  • Handover
    Complete installation paperwork and system guidance will be provided for your records.
  • Peace of mind
    Our UK team monitor your system, supporting you promptly and reliably.

Everything you need to know about renewable energy for your home

Is renewable energy really better for the environment?

Yes. Solar panels, battery storage and air source heat pumps all help cut reliance on fossil fuels. Solar generates clean electricity from sunlight, batteries make the most of that clean energy by storing it for later, and heat pumps replace gas or oil heating with a low-carbon alternative – together reducing your carbon footprint.

Can I stay at home during installation?

Yes, you can usually stay at home throughout. Solar and battery installations are typically completed within one to two days, while heat pump installations usually take longer – often several days – depending on the property and system. Whatever the timeframe, installers work efficiently and safely to keep disruption to a minimum.

 

 

Do I need solar panels to have a battery, or a battery to have solar?

No – each can work independently. Solar panels alone reduce reliance on the grid, a battery alone lets you store cheap, off-peak electricity to use when rates are high, and the two together give the greatest savings* and energy independence by storing your own generated power to use whenever you need it.

 

 

Do you need planning permission?

In most cases, solar panels and air source heat pumps can be installed under permitted development rights, so planning permission isn’t usually required. Battery storage typically doesn’t require planning permission either. This is always checked during your survey to ensure your installation meets local regulations.

 

 

Will renewable technology increase the value of my home?

Solar, battery storage and heat pumps can all make a home more appealing to buyers, particularly those looking for energy-efficient properties. Lower running costs* and improved energy performance are often seen as valuable long-term benefits.

 

 

Do solar panels and heat pumps still work in winter?

Yes. Solar panels continue generating electricity through winter – output is lower due to shorter days, but they still work efficiently in daylight. Air source heat pumps are designed to perform reliably in UK winter conditions, extracting heat from the air even at low temperatures.

How do I know which system is right for me?

It depends on your goals: solar alone reduces bills by generating your own electricity, a battery lets you cut costs using off-peak rates, solar plus battery maximises savings and independence, and a heat pump replaces your heating system for lower running costs and emissions. Our team can help you choose the right combination for your home.
