Renerji: integrated renewable energy installations in the south of England

Renerji is a company specialising in the design and installation of integrated renewable energy systems for homes and commercial properties in Dorset, Hampshire and Wiltshire. Its work covers air source heat pumps, solar PV systems, battery storage and electric vehicle charging points. The company presents itself as an integration specialist: the different pieces of equipment are designed to work together and maximise the efficiency of the whole system.

Based in Hampshire, Renerji operates across the south of England and has completed more than 300 installations. The team has over 40 years of combined experience and holds MCS, TrustMark, NAPIT, APHC and HIES certifications.

Renewable energy services for homes and businesses

Renerji's offering covers four main areas, aimed at both private homeowners and businesses and owners of commercial properties:

• Air source heat pumps: low-carbon heating systems, installed and commissioned by MCS-certified engineers. The company handles the Boiler Upgrade Scheme grant application, worth £7,500 for eligible homeowners.
• Solar PV systems: installations designed to integrate with heat pumps and battery storage, with the aim of reducing energy costs.
• Battery storage: smart systems that store the energy generated by solar panels and manage it alongside the heat pump to keep costs down throughout the day.
• EV charging: smart home chargers installed by the qualified team, which allow you to take advantage of cheap overnight tariffs and can be combined with solar and battery to reduce charging costs.

For the commercial segment, Renerji offers heat pump systems, large-scale solar PV installations, battery storage, EV charging infrastructure and energy monitoring and reporting services.

Working process: from initial survey to monitoring

The company structures its projects in several phases. It begins with a no-obligation property visit to assess the heating, energy consumption and roof, and to recommend the most suitable combination of technologies. It then produces the integrated system design and a detailed quote, and confirms eligibility for the Boiler Upgrade Scheme grant, handling the application where applicable. The installation is carried out by certified engineers, who also take care of commissioning, explain how the system works and provide aftercare support.

Renerji makes interactive tools available to interested parties to obtain instant estimates: a roof analysis and indicative price for solar installations, and a property assessment and sizing for heat pumps. According to the company, the quoting process can be completed in under three minutes without the need for a phone call.

Boiler Upgrade Scheme grant

Renerji handles the application for the government's Boiler Upgrade Scheme (BUS) grant, which provides £7,500 towards the installation of an air source heat pump. The company states that homeowners who replace a gas boiler, an oil boiler or electric heating may be eligible, provided the property is in England or Wales, the grant has not been claimed before and there is a valid Energy Performance Certificate (EPC). Renerji handles all the paperwork at no extra cost.
