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.


  • 94% of compounds were fitted with energy saving devices (2016: 84%)
  • By the end of the year all fork lift machines with a less than 17 metre reach were fitted energy efficient engines – this represented 78% of our fork lift fleet.
  • 3,723 homes incorporated renewable and energy saving technology (2016: 3,351)
  • Our homes constructed achieved an average dwelling emission rate (DER) of 6.04% better than building regulations (2016: 5.67% better)
  • An energy saving campaign was trialled in 3 divisions

Performance against 2016/17 target

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

By the end of the year 94.0% of our compounds were fitted with energy saving devices (2016: 84.3%)

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

83.5% of our forklift fleet has now been fitted with 55 watt engines (2016: 68.9%)

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

The campaign has now been launched in 3 divisions. We will assess its effectiveness in reducing energy usage before considering a roll-out to all divisions throughout 2018

Comparative Data

Percentage of homes developed on Brownfield Sites

For the 2017/18 Bellway financial year, we have set a range of targets across our three CR themes (Environment, Construction, and Society and Economy). We have prioritised these targets and published our top 12 priorities across the themes for this financial year. This approach allows us to focus our efforts on the areas of greatest impact, while continuing to work internally on our additional targets.

Below you can find our public targets relating to energy.


We will ensure that 100% of our compounds are fitted with energy saving devices by 2020

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

We will roll-out an energy saving campaign to all divisional offices as a trial to measure and reduce office energy use (measured in kwh per employee)


We have continued to introduce compounds fitted with a range of energy saving devices to drive down energy usage and have 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 the latest emission factors from the 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. Our carbon footprint is externally verified by Zeco Energy to a ‘reasonable assurance level’, as well as subject to scrutiny by our external auditors KPMG.

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.


All our new homes are designed to, as a minimum, 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 where possible 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

Energy Saving

For the proposed development of 176 new homes at the Brambles (Coventry), Bellway South Midlands oversaw the incorporation of design measures capable of reducing the site’s energy requirement by over 12%. The energy efficiency measures incorporated into the detailed design of the site/homes included:

  • High levels of insulation in the ground floor, external walls and roof spaces.
  • House designs incorporating the thermal bridging guidance to reduce significant sources of heat loss.
  • Efficient gas condensing boilers in each property, including dual zone heating controls with delayed start thermostats.
  • Energy efficient lamps installed in every light fitting.
  • Properties naturally ventilated using efficient decentralised extract fans.
  • The white goods installed will be energy efficient with an A+/A rating.

In addition, roof mounted PV arrays were installed on a number of homes to further reduce the site’s energy requirement.
