Imtech Engineering Services provides design, installation and commissioning solutions through our regional businesses in the North, Central, Scotland and London & South across a wide range of sectors including health and social care, education, leisure, commercial and retail. 

Suir Engineering

Suir Engineering in Ireland has over 30 years of mechanical, electrical and instrumentation expertise with many blue chip clients in sectors including commercial, health and social care, manufacturing and industrial, science and technology and utilities.

Technical Facilities Management

Imtech Inviron supports clients in a number of sectors, undertaking the transition of new buildings through practical completion into successful facilities management operations and the maintenance and upgrade of existing facilities.

Systems Integration

Capula, Imtech’s systems integration business, is one of the leaders in its sector. Capula focuses on providing advanced automation control and real-time IT solutions across the built environment and infrastructure, in particular for the nuclear, renewable energy, power generation, oil and gas and process industry sectors.


District Heating Networks

Barkantine Heating Network (London)

The Barkantine Heat and Power Company (BHPC), a subsidiary of EDF Energy Services is a local initiative that harnesses a leading energy efficiency strategy.  The energy centre and distribution infrastructure provides heat to both residential and commercial customers.

The Energy Centre and heating network incorporates a 1.4MWe CHP engine to meet the baseload heat requirements, and four 1.4MWth heat-only boilers for top-up and peak load requirements. The heat is distributed through 2.4 km of underground mains. To date, BHPC has achieved its main objectives: carbon savings - saving 2500 tonnes of CO2 per year and, energy efficient – up to 30% more efficient than conventional heat and power systems and cost effective - providing savings for customers on energy costs.


Aerospace Industry

Imtech Inviron have provided technical facilities management for a large supplier to the aerospace industry since 2009. We ensure that the client can deliver precision products to their customers in complete confidence that the technical services across its complex design and manufacturing facilities are maintained to the highest standards.

We advise and work closely with the client to deliver solutions to reduce its CO2 emissions and help achieve its energy efficiency targets. We undertook a project to upgrade lighting, in one of its’ main buildings, to energy efficient luminaires in conjunction with occupancy and daylight sensors. Since completion, the original estimated saving of £81k per annum has been exceeded, initial costs recovered and energy savings realised.

Energy efficiency

United Biscuits

Energy Services at EDF Energy conducted energy audits at seven of UB’s sites, which included comprehensive ESOS energy audits at four of UB’s main sites in the UK. The objective of these audits was to assess the energy performance and recommend cost-effective energy efficiency savings.

Installation of PV and CHP systems contributed directly to monetary savings of approx. £ 501,500, as well as a reduction of 7191 MWh in electricity consumption and 1961t of greenhouse (CO2) emissions.

Building Energy Services

Chase Farm

On target to open in Autumn 2018, Chase Farm will be operated and maintained by EDF Energy Services. The energy centre will provide power, heating and hot water for the new hospital, using a highly efficient and low carbon combined heat and power plant. This 15-year contract will reduce carbon emissions by 27% saving over 17,000 tonnes of carbon and producing savings to the hospital of nearly £7m over the term of the contract.

Large thermal stores will be used to store excess heat generated by the plant and allow it to be used in the hospital when it is needed – as well as being able to export any power not used back to the national grid.

Low Carbon Solutions

Imtech Low Carbon Solutions

Imtech have been commissioned by the London Borough of Hounslow to design, supply, install and maintain a roof mounted 1.68Mwp Solar Photovoltaic array (6000 solar panels) complete with battery storage to maximise use of renewable energy on site. This decentralised plant will generate over 1,529,640 kWh per annum reducing the local authorities’ carbon footprint by 791 CO2, the equivalent of removing 204 UK cars from the road every year.
