Our mission is to promote the sustainable use of energy, reducing carbon emissions AND saving our clients money.

In pursuing this mission we will assist our clients by:

providing independent expert advice identifying cost-effective opportunities to reduce energy use and/or improve efficiency promoting the sustainable use of renewable and low carbon energy technologies complying with local and national legislation (e.g. building control, Energy Performance Certificates) engaging their staff and others in the process effectively measuring, monitoring and reporting on progress.

We have been involved in energy conservation since the deregulation of the electricity supply industry some 20 years ago, initially carrying out energy audits and site load profiling using the Hawk™ portable energy logger and Hawk Reporter™ electricity tariff analysis software. Since then we have expanded our experience to include consultancy, training, compliance services, carbon reduction and specialist renewable energy services (e.g. Independent Metering Reports for the Renewable Heat Incentive).

Other Services

An energy audit:

Is a systematic measuring and recording of energy consumption Identifies what energy is being used and where Seeks opportunities to reduce energy consumption while maintaining and improving human comfort in buildings Prioritises opportunities for energy savings from greatest to least cost effective.

An energy survey:

Is a detailed investigation on the feasibility and potential savings from a specific energy saving opportunity.

Why have an energy audit - what are the benefits?

An energy audit identifies in which areas you should expend effort and expenditure. It allows comparison with existing benchmarks, or establishes performance benchmarks specific to your own estate. It contributes to justifying investment decisions, reputation and corporate social responsibility (CSR).

Carbon foot print 

Our Carbon Foot Printing service is based on the Carbon Trust’s methodology for SMEs using concepts developed by the World Resources Institute and the World Business Council for Sustainable Development in the GHG protocol.

Key principles are Transparency, Pragmatism, and Consistency for organisations seeking a basic understanding of their carbon footprint. It is not a substitute for a full analysis of an organisation’s corporate emissions inventory using the GHG Protocol or ISO14064.

Scope 1 Direct emissions:

Cover all emissions that an organisation directly causes and controls, e.g. gas or oil used onsite.

Scope 2 Indirect emissions:

From imported utilities, the most common being emissions from purchased electricity. This accounts for allemissions from power stations that have generated the electricity. Other emissions covered under Scope 2 are those arising from the import of heat, hot water or steam.

Scope 3 Indirect emissions:

Are all other emissions that an organisation causes to occur but which it does not control. Common types of indirect emissions include emissions from transport in vehicles owned by other organisations or emissions from outsourced activities or from an organisation’s supply chain. The process includes data gathering and calculation of emissions from the following:

Renewable energy feasibility studies

Basic Assessment Study

The aim of this report is to enable clients to make an informed judgement about which of the various renewable and LZC (low and zero carbon) technology options is most suitable for their particular circumstances. A basic assessment is often carried out at the design stage of a project, forming part of the planning application. The assessment considers the following technologies:


Solar Thermal

Solar PV


Combined Heat & Power (CHP)

Our basic assessment service comprises a desk based study, the output of which is a report that includes:

Wind resource, solar resource, heat load estimates, electrical load estimates

An estimation of the total annual energy consumption of the building(s) based on data provided by the client

A calculation of required percentage to be offest by renewable and LZC technologies to meet planning requirements

An initial assessment of how this energy could be supplied from renewable and/or LZC technologies for consideration by the client

Heat Pumps

The assessment includes one meeting on site, but excludes travel which will be charged at cost.

Options review 

Optional post-assessment meeting with client to review the findings of the basic assessment study.

The meeting could include input from the client, client’s architect, and M&E design team.

Should further work be requested as a result of the review, for example the detailed feasibility study of option(s), we will provide a fee proposal to your exact requirements.

Hydro Studies

Humans have harnessed water power to do work for thousands of years. Modern hydro systems convert the potential energy stored in water to electricity. Useful power, from a few hundred watts through to several kWs, can be obtained for domestic, community, or commercial use. Determining the potential output from a resource is a two-step process.

Step One: Consists of a desk based assessment to establish the size of the potential resource size and to advise if the site is worthy of more detailed investigation. Clients should provide: OS grid references for the site and land boundaries. A site visit is not normally included at this stage, but is available on request at extra cost.

Step Two: Is a more detailed feasibility study, normally carried out if further investigation is warranted following the desk top study. This typically comprises the following:

Resource assessment, estimation of river flow duration curve

Site visit and survey to assess available head, intake and powerhouse locations, pipe route

Possible abstraction regime (Environment Agency, planners and regulation bodies)

Identify potential connection problems (for grid connected systems, a study fee may be required by the local grid operator)

Estimates of scheme development costs

Operation and maintenance issues and associated cost estimates

Estimated annual energy generation and gross annual value

Recommendations for further work



A Display Energy Certificate shows the energy performance of a building based on actual energy consumption as recorded annually over periods up to the last three years (the Operational Rating). The DEC also shows an Asset Rating for the building if this is available (by way of an EPC). A DEC is valid for one year and must be updated annually.

An Advisory Report accompanies the DEC and contains recommendations for improving the energy performance of the building. 

If you are an occupier of a building requiring a DEC, you will need to display a DEC showing an Operational Rating in a prominent place clearly visible to the public and have in your possession or control a valid advisory report. Full details about DECs, what they are and what they contain, can be found on the CLG website.

TM44 Airconditioning

The EPBD calls for all air conditioning systems with an effective output of 12kW or more to be assessed for energy efficiency at least every 5 years.

An ‘air conditioning system’ comprises ALL of the individual units at a site that are under a common management control – i.e. the control of the same person or organisation. This means it is not necessary to have one large cooling system - a site with several individual small split-cooling units is likely to come under the legislation. The F-gas regulation came into force in July 2006 with key obligations becoming mandatory in July 2007. Maintaining records is a key obligation under the F-gas regulation. 

Further information about air conditioning inspections can be found on the Communities & Local Government web site.


EPCs (Energy Performance Certificates) for non-domestic buildings

An EPC looks broadly similar to the energy labels now provided with vehicles and many household appliances. Its purpose is to indicate how energy efficient a building is. The certificate will provide an energy rating of the building from A to G, where A is very efficient and G is the least efficient. The better the rating, the more energy-efficient the building is, and the lower the fuel bills are likely to be. Each energy rating is based on the characteristics of the building itself and its services (such as heating and lighting). Hence this type of rating is known as an asset rating.

An EPC is required for the sale or let of all properties from 1 October 2008.

An EPC must be obtained before a contract to sell or let is entered into.

Further guidance on Energy Performance Certificates (EPCs) for commercial property (non-domestic) can be found on the CLG website.
