City Energy: providing ECO funding solutions to the UK.

City Energy are specialist ECO providers that offer no nonsense explanations on ECO funding and the Green Deal that are easy to understand and will make everyone’s life that little bit greener.

City energy works to provide homes with affordable warmth and to alleviate fuel poverty. We work closely with the public and private sectors to maximise funding opportunities which enable individual and area wide energy efficiency schemes.

We’ve gained a reputation for being respected providers of energy efficiency advice and renewable technologies through our knowledge and expertise in delivering projects requiring complex funding. As well as delivering large government funded projects, we also provide grants for domestic and large scheme connection to the gas network.

Working with housing associations and local authorities, our affordable funding model delivers sustainable and affordable homes which make the most of income from renewable technologies. The income remains in the communities, ensuring they benefit in future years.

The Energy Companies Obligation (ECO) was introduced in early 2013 by the government and aims to help low-income households and low-income areas make energy efficient improvements to their homes.

Under ECO, it is the the big six and the smaller energy suppliers’ duty to help householders save on their energy bills and reduce carbon emissions.

Based in the heart of South Wales, City Energy have a central office in Cardiff providing services to Swansea, Newport, Bristol and across UK, whether it’s turning the light off or having a Green Deal Advice Report carried out on your property City Energy cater for all your energy needs.

From a new boiler to renewable energy, cavity wall and solid wall insulation to loft insulation, we will help make your home more energy efficient.
