We will help our customers reduce their energy consumption by providing more than 90% energy efficient lighting in our new homes.

All lighting installed in new homes was energy efficient in 2014/15.

We will seek to design new sites to achieve an average energy efficiency of at least 5% better than the applicable building regulations standard.

Average efficiency rate was 9% better than the applicable building regulations standard.

We will aim to ensure that 100% of new and hired-in construction compounds will include at least 2 energy saving devices, bringing the percentage of all compounds with energy saving devices fitted to at least 60%

By the end of the year 84.3% of compounds were fitted with energy saving devices, compared to 52% in the previous year.

We will, at the planning stage, aim to design our homes to have a site Dwelling Emission Rate that is 5% better than required by the relevant building regulations.

Homes constructed in the 2015/16 year achieved an average DER of 5.67% better than the applicable building regulations.

We will aim to undertake energy audits at a minimum of 2 divisional offices to identify energy saving opportunities that can be implemented across our office estate

Audits were undertaken at 2 offices and relevant findings have been taken forward for implementation.

We will increase the proportion of construction compounds with energy saving devices to at least 90%.

We will limit the engine size of fork lifts to 55 watts on all sites by 2019, delivering fuel and carbon savings.

We will develop a ‘best practice’ energy saving campaign, implement in 1 division and assess its impact prior to considering roll-out across the wider business.



Becoming more energy efficient, both in our own operations and in the energy performance of the new homes we build, is an important part of our CR strategy. We have continued to introduce compounds fitted with a range of energy saving devices to drive down energy usage, increasing the proportion of developments with such compounds from 52% to 84%. We have also introduced standardised guidelines and procedures for the use of heating in our show homes and sales offices to drive further efficiencies.

Carbon Footprint

We calculate our annual carbon footprint using emission factors from the 2016 Government GHG Conversion Factors for Company Reporting. The results are reported to the Carbon Disclosure Project as well as published in our latest Annual Report. For the second year our carbon footprint has been externally verified by Zeco Energy to a ‘reasonable assurance level’, as well as subject to scrutiny by our external auditors KPMG. More details on our carbon footprint can be found under the climate change section of this report.

Energy Audits

As part of the Energy Saving Opportunity Scheme (ESOS), we undertook energy efficiency consumption audits at some of our offices and development sites with a view to identifying a range of energy saving initiatives that could be rolled out across the Group. Initiatives identified included:

  • Installing more energy efficient lighting
  • Controlling the heating via thermostats
  • Potential for photovoltaic panels on office roofs
  • Use of timed devices and sensors to control lighting
  • Training employees and sub-contractors in energy efficiency good practice

Work in the coming year will include the trial of energy saving campaigns in divisions and the production of best practice energy efficiency guides for offices. 

Number of home with energy saving and renewable technoloy


All our new homes are designed to meet the energy efficiency criteria set out in the relevant building regulations, and in many cases we exceed this criteria. This helps our customers minimise their running costs and their impact on the environment once they have taken ownership of the property. Where appropriate we may use a range of renewable energy technologies on developments, such as solar panels, photo-voltaic panels, air source heat pumps and ground source heat pumps. Lighting in new homes is energy efficient while boilers are ‘A’ rated for energy and going forward we will be introducing ‘dual zone’ heating capability into all our news homes to further improve efficiency. In addition all windows are double-glazed and kitchen appliances are A-rated or better for energy consumption. All these initiatives help to lower the energy bills for our customers. 



Our informative home owner packs include our ‘Go Green’ information sheet, developed specifically for customers to help them make informed environmentally-friendly choices about how they live in their property, ensuring that they have the best possible experience of a Bellway home from the moment they move in.


Case Study Case Study

Renewable Energy

As part of our site in Bishopstoke, Eastleigh, the borough council’s sustainability policy required that all new housing developments comply with energy efficiency levels equivalent to Code for Sustainable Homes Level 4, as well as for 15% of the total development’s energy usage to come from a renewable source. This combined requirement was the equivalent of the homes being 19% more energy efficient than required by Part L of the 2013 Building Regulations. We were able to deliver this by improving the energy efficiency of the building fabric in the homes as well as by installing PV panels to each plot on the development.
