The varied opportunities at British Gas make it an exciting place to work. There are more than nine programmes available to graduates alone including engineering, HR and finance. The recruitment process is very similar to Centrica’s with a few variations. This article deals with the four common stages of the application process.

British Gas Recruitment Process

British Gas Application Form

British Gas and Centrica share an application. The online application form is a very important part of the Centrica application process. As well as entering in all your personal information and qualifications you will also have to answer a number of competency questions. These questions are designed to help you show your ability levels in a regular everyday setting.

In your answers you need to demonstrate that you have Centrica key competencies and have put them into practice throughout your life so far. The competencies are known in Centrica as “Leadership behaviours”. They are:

  • Being one team - Build and maintain effective working relationships.
  • Creating a positive environment - Have a positive impact through self-awareness and social skills.
  • Putting our customers first - Deliver excellent customer service.
  • Seizing responsibility - Take initiative and set high standards for self.
  • Seeing beyond our own goals - Look at the bigger picture and recognise the impact of your actions.
  • Learning agility - Learn from experience to perform in new or changing situations.
  • Drive - Focus energy on what will make a difference and deliver exceptionally.
  • Manages relationships - Communicate/collaborate effectively to get the best from people.

You need to show that you possess these qualities and incorporate them into your answers. You do this by using the STAR method where you explain how you have used these competencies through a real-life situation.

Once you have completed the Centrica PLC online application form you will then have three separate online tests.

British Gas Online Tests

As part of the application form are asked to take part in the British Gas online ability tests. These form part and parcel of the online application for British Gas and you need to complete them in order to progress to the next stage. There are four possible tests that you will have to take and we will go through them below. These tests are provided by the Criterion Partnership test company.

Numerical Reasoning Test

In this test you are given some numerical data in the form of tables and graphs. You are then given a series of business- related multiple choice questions to answer. These tests assess your ability to identify trends across a range of data and combine statistics from different sources to establish new information patterns. Numeracy skills are important to British Gas and your score in this section helps determine whether or not your application moves forward. Make sure to get the preparation you need with our Utopia-style practice numerical reasoning tests

Verbal Reasoning Test

In this test you are given a paragraph of information on a certain subject with a statement about the text below. You have to answer as to whether you think the statement is true, false or cannot say. These tests are used to measure different aspects of critical thinking and reasoning. Get ahead of the competition with Utopia-style practice verbal reasoning tests.

Personality Questionnaire

This questionnaire is used to find out about your personality in relation to various stresses that will happen at work. They can also be used to understand your approach and values relating to the job. You will be given a number of statements and you have to select which of the statements you highly agree with to disagree with on a scale. Understanding how these tests work will enable you to give over the right impression. Although there are no right or wrong answers to this test, knowing how to answer personality questions is essential. Learn more about our personality tests on our dedicated page.

Situational Judgement Test (SJT)

As well as the above three tests, you are required to take a situational judgment test, or SJT. This test is used to measure your ability to decide effective ways to handle real life situations, including behavioural and managerial skills. Familiarise yourself with this type of test with our practice SJTs

British Gas Mechanical Reasoning Test

For candidates applying to apprenticeship roles, you may be asked to take a mechanical reasoning test. This is a 20 minute multiple choice tests where you are asked questions relating to your mechanical knowledge. As an example, a question may include a diagram of two cogs and you are asked how cog X is expected to move if cog Y one direction. As this is a specific skill set British Gas is looking for, it’s important to show the best of your abilities here and using our mechanical reasoning practice pack can help you do just that.

British Gas Telephone Interview

Depending on the role you have applied for you may be invited for a telephone interview. This interview can focus on general competencies and/or a role play. The type of interview you encounter depends on the role you apply to and you are told beforehand what types of questions you can expect. Each position at British Gas has its own set of competencies which are listed on the job application form. Review the competencies before your interview and have a real life example to give. A mock interview is a great way to prepare yourself for the interview and you can use our Skype interview preparation pack to get yourself ready 

If you are successful in this interview you will be asked to attend a British Gas assessment centre.

British Gas Assessment Day

The final stage of the application process is the British Gas assessment centre day. After a brief presentation from British Gas you may be asked to participate in any of the following activities:

Verification of British Gas Online Tests

These are a repeat of the previously taken online ability tests in order to verify your scores. Make sure you have done extra practice for these tests as they may be longer than the 15 minute tests that you have already taken.

British Gas Role-play Exercise

The content of the role-play exercise depends on what role you have applied for. One typical situation you could face is an irate customer who complains about the bill, the service, or anything else that comes to mind. Another situation is that you are asked to try and sell something to a customer. This exercise lasts for about 10 minutes and you can prepare yourself fully for this by having a full understanding of the competencies that British Gas wants to see in you. As this exercise shows off important skills to the assessors, a good performance is vital. Learn more about role-play exercises on our dedicated page.

British Gas Competency Based Interview

This interview is based on the answers that you gave in your previous online ability tests and tests your competency levels as well. Make sure to go over the job description and try and remember exactly how you answered in your ability tests. As well as this, it is very worthwhile to get someone to give you a practice interview. Our face-to-face interview pack can help you prepare for this stage of the assessment day.
