Performance – people

We want to see equal opportunities for all and people to succeed to their best of their abilities, regardless of background, personal challenges or circumstances.

Safety and wellbeing

Safety is a core value held by every one of us at National Grid and underpins everything we do. Any incident is one too many and we continually strive to improve safety for our employees, contractors and the public. 

We take safety very seriously at National Grid – it remains a fundamental priority – and we will do everything we can to learn from incidents, so we can continually improve our performance.

Both our UK and US businesses remain committed to achieving the highest possible standards for safe working.

Our workforce

Some of our employees will always be exposed to high-risk working environments on a daily basis. 

We are committed to raising the standards of visible safety leadership across the business and supporting a culture of instinctive safety in our people. We continue to foster the belief across our businesses that all accidents can be avoided.

Operating major hazard sites and pipelines means managing process safety risks is always a prime consideration in the way we run our business. We continue to aspire to be an industry leader in this area. 

For the year 2017/18

  • Employee lost time injury frequency rate (IFR) was 0.10, equalling the safety level rate we achieved in 2016/17.
  • There were 52 employee lost time injuries, 9 less than in 2016/17.
  • 69 high-potential incidents were identified, compared with 94 last year.

Members of the public 

The safety of the public in the communities we serve is of prime importance to us.

In 2017/18, four members of the public were injured as a result of our activities, compared with 14 in 2016/17. 

Following the sale of our Gas Distribution business in March 2017, the risk of injuries to members of the public in our UK operations has dropped significantly. The injuries we have had were in our US business and were from road-traffic collisions and one instance of a member of the public entering a work area and falling into an excavation.

Those who work for us 

We believe everyone who works for us is entitled to high levels of safety, whether they are a direct employee or employed by one of our contract partners.

During 2017/18 there were 31 contractor lost time injuries, compared with 34 in 2016/17.

National Grid is committed to support and, where possible, help employees improve their health and wellbeing. Our focus is on mental wellbeing and stress management, physical wellbeing and diabetes awareness. 

We provide support for employees through training as well as our occupational health services, employee assistance programme and physiotherapy services.


To achieve our strategic objectives, we need to make sure our employees have the right skills and capabilities. Equally, having the optimum workforce for our business means our growth is more likely to be long term.

We are involved in a number of initiatives to help attract new talent into our organisation and industry. More information on these can be found in the Responsibility and Sustainability section of our website.

We negotiate with recognised trade unions. Around 27.36%* of employees are members of a trade union in the UK and 61% of our employees are members in the US. Globally this equates to around 44% of our employees who are members of a recognised trade union. Those not covered by a Collective Bargaining Agreement are management grade employees in the UK and non-trade union members in the US. 

There have been no material disruptions to our operations from labour disputes during the past five years.

* This figure represents those employees who pay through payroll for union membership and will not include any private payments for employees who pay for membership via direct debit.

Employee engagement 

We measure how engaged our people are through our employee engagement index, calculated from certain questions in our annual employee engagement survey.

The results of our 2018 survey, which was completed by 87% of our employees, have helped us identify specific areas where we are performing well and any areas where we need to improve. Our engagement index has remained the same this year, at 77% favourable. From the survey results, action plans are put in place at company, regional, business unit, function and team levels.

​​​​Talent and skills

To achieve our strategic objectives, we need to make sure our employees have the right skills and capabilities. Equally, having the optimum workforce for our business means our growth is more likely to be long term.

We remain committed to investing in our people, providing the training and other support necessary for them to build, maintain and operate our networks safely and reliably. During 2017/18, we provided over 1.2 million hours of training for our employees. This equates to around 6.5 hours per employee. 

Our training focuses on technical, safety, leadership and personal effectiveness training across our workforce. We see these capabilities as crucial in helping us improve our performance and meet customer expectations.

Inclusion and diversity

We aim to develop and operate our business with an inclusive and diverse culture; with equal opportunity in recruitment, career development, training and reward. This applies to all our employees, regardless of race, gender identity, nationality, age, disability, sexual orientation, religion and background. Our policies support the attraction and retention of the best people, improve effectiveness, deliver superior performance and enhance our success.

As at 31 March 2018, 24.6% of our 23,023 employees were female and 17.9% were from ethnic minority groups. Around 31% of our senior management team are female and around 8% are from ethnic minority groups.

As at 31 March 2018, 38% of our Board members were female and 7% were ethnic minorities.

We continue to support Stonewall, the Business Disability Forum and Inclusive Employers.

Code of Ethical Business Conduct

Our Code of Ethical Business Conduct provides a common set of practical guidelines to help make sure our behaviours are lawful and comply with our policies and licences. It applies to all employees, from the Board down, and defines the values that underpin our everyday decisions. 

Our Ethics and Compliance Office provides our employees with information and advice on ethical issues. It also operates our Business Conduct Helplines, which allow our UK and US employees to raise any ethical concerns (anonymously if desired) they may have. 

In 2017/18, there were 148 substantiated breaches of our Standards of Ethical Business Conduct. This equates to 6.4 substantiated breaches of the Standards per 1,000 employees compared with a total of 73 in 2016/17.

We take all breaches very seriously and disciplinary action can range from a verbal warning to dismissal. In 2017/18, there were 32 terminations of employment (2016/17: 31) resulting from substantiated breaches; for offences such as fraud and theft, drugs and alcohol abuse, safety violations and misuse of company assets, and discrimination, bullying and harassment.

During 2017/18, around 96% of our US and 94% of our UK employees completed training on ethics.
