iCOZi: electric heating and renewables for homes in the UK

iCOZi presents itself as a supplier and installer of modern electric heating systems, high heat retention storage heaters, solar panels, battery storage and thermal store hot water solutions. The company operates across mainland UK — England, Scotland and Wales — and targets both homeowners and property managers.

Its approach is based on a free, no-obligation technical survey, in which heating requirements, room characteristics and the existing electrical installation are assessed. From that analysis, they produce a heat-loss calculation to size the equipment and present a specification tailored to each property.

HHR+ high heat retention storage heaters

The company supplies and installs Elnur HHR plus high heat retention storage heaters for electrically heated homes. According to the company's information, these units are designed to retain stored heat for longer and offer greater control over when it is released compared with older storage heaters. Regulations require high heat retention storage heaters to store 45% of unused heat over 24 hours; Elnur states that its units achieve 51%.

The HHR plus can work with Economy 7, Economy 10 and some smart or time-of-use tariffs. They are controlled via Wi-Fi and can use surplus solar energy through separate control boxes. Four models are available, with outputs of 270 W, 550 W, 820 W and 1,100 W. Choosing the right size depends on factors such as the room and its heat-loss characteristics, the electricity tariff, the meter configuration and heating usage habits.

The service includes a free, no-obligation survey, heat-loss calculation, electrical assessment, solar PV assessment if panels are already installed, supply and installation by qualified electrical engineers approved by iCOZi, system programming and setup, and post-installation telephone support. The company identifies itself as an Alcumus SafeContractor approved contractor.

PROSSH smart Wi-Fi storage heaters

iCOZi also offers a complete supply and installation service for Elnur PROSSH smart Wi-Fi storage heaters across mainland UK. These units combine stored heat with integrated boost elements, which can help heat the room more quickly when additional heat is needed. They incorporate smart charging technology that manages when energy is stored to avoid unnecessary charging.

Wi-Fi control is via the free Elnur app, provided the G Control Hub is installed, which is sold separately. They also support voice control through compatible Alexa and Google Assistant functions, using the relevant apps or skills to turn the heating on or off, raise or lower the temperature, adjust the temperature of a specific room or change the operating mode.

The replacement process includes a free, no-obligation survey, heat-loss calculation, removal and disposal of old storage heaters, supply and installation of the new units, programming and setup, and post-installation telephone support at no extra cost. Installations are carried out by engineers qualified in electric heating and the company holds Alcumus SafeContractor approval. Prices published on the website are subject to survey and exclude VAT.

Technical survey and working process

The starting point is a free, no-obligation survey that iCOZi carries out at the property. This includes a technical study and a heat-loss calculation to determine the requirements of each room. The customer then receives a supply and installation quotation based on the identified requirements. Installation includes the removal and disposal of existing storage heaters, the installation of the new units and their programming. Post-installation telephone support is part of the service.

Scope and property types

iCOZi's high heat retention storage heaters are intended for a variety of electrically heated properties, such as houses, flats, residential homes, social housing, commercial premises and retirement accommodation. The company serves England, Scotland and Wales.
