Our Services 

Battery Installation

We are MCS Accredited battery installers, installing standalone systems to use cheaper off-peak tariffs; as part of a new solar install, or to add to an existing setup.

Repair & Maintenance

We maintain and repair domestic & commercial solar installations. We can provide condition reports on existing systems and upgrade older installations.

Domestic Solar PV Installation

Record numbers of people are choosing to install solar panels in the UK. 


With the rising prices of energy, and the reduction in the cost of solar panels, there has never been a better time to chose to generate your own energy, reducing your costs and your carbon footprint, as well as selling any excess energy that you generate back to the grid.

We design systems specifically suited to your needs, maximising your energy yield for the most affordable price. Choosing to add battery storage will allow you to use the energy you generate at night, as well as giving you access to cheap off-peak tariffs to charge your battery when you cannot generate enough power. You can divert your excess power to heat your water, and even replace your gas boiler and incorporate your heating needs too.

We are MCS accredited installers, and members of RECC and Trustmark. Your equipment and installation will have comprehensive warranties, and we guarantee our work will be of the highest standard.

To find out how installing solar panels could benefit you, and for an obligation free assessment and estimate:

Modified Ltd was established in 2018 as a building company providing refurbishments and renovations for domestic and commercial properties. With a speciality in electrical installation and testing by our in-house fully qualified electrician, we are able to undertake all aspects of building renovations, including plumbing and electrical installations.


Over the past few years, our focus has shifted to meet the growing demand for renewable energy, and we now focus mainly on installing and maintaining solar photovoltaic installations and energy storage systems, for both the domestic and commercial market.


We are certified by MCS for both Solar PV and Battery Installation, registered with NAPIT, and are members of the Renewable Energy Consumer Code (RECC), and the UK Government’s Trustmark organisation.




Domestic Solar PV Installation

How it works:

Want an obligation free assessment & quote?

You contact us, either by sending us a message using the enquiry button, or calling us on the number given above, and we book in an no-obligation assessment of your property to discuss your usage requirements and generation capacity.

We visit your property to take measurements, check your existing electrical installation and current usage, and use a drone to inspect your roof, taking images to assess any shading issues.

We then provide you with a comprehensive estimate of the generation capacity of a suitable installation, and a full quote pack and contract.

If you choose to go ahead, we book in the scaffolders, roofing contractors and electrical installation team, and make all the necessary applications to the DNO. The installation usually takes between 2-3 days.

Your system is tested, commissioned and fully operational. We provide you with the MCS and Electrical Certificates, DNO and Building Control notifications, and a full handover pack including manuals & warranties for all of the equipment. We show you how everything works, and help you choose a suitable import & export tariff with your energy provider.

…you sit back & enjoy your free power, 

knowing that you are also doing 

your bit to help save the planet!
