Delivering for our customers
By asking this question – what do our customers want and need from us? – of customers of all ages and walks of life, we make sure our service is truly responsive.
We continue to listen to and understand our customers needs by working closely with them and our stakeholders – whose feedback helps to guide and develop our services and shape our strategic business decisions.
To make sure we deliver a great service to customers, our regulator, Ofgem, sets performance standards. These are known in the industry as Guaranteed Standards of Performance (GSOP).
If we fail to meet these standards, customers are entitled to compensation. You can find out more information about all this in our Standards of Service.
Outputs - a detailed look
Customer service | Target | Status | |
---|---|---|---|
Unplanned interruptions (score out of 10)Unplanned interruptions are issues such as gas escapes, which result in the gas going of suddenly and without warning. Each year, Ofgem carries out surveys among a cross-section of customers affected by such an interruption, to gauge their level of satisfaction with our response. Our score of 9.55 is ahead of target, and in line with our outperformance throughout RIIO GD1. The professionalism and dedication of our emergency engineers had a lot to do with this great performance. |
9.0 | Ahead | |
Planned interruptions (score out of 10)Planned interruptions are periods when the gas goes off for essential repair or maintenance work. Customers are given advanced notice, usually through letters. Our score of 8.92 is ahead of target and in line with our outperformance throughout much of RIIO GD1. Lots of elements went into this strong performance, including the use of detailed mitigation plans for each job, to minimise inconvenience, and weighting our programme of work, so that fewer jobs are carried out in winter, when the impact of losing gas is more acute. |
8.5 | Ahead | |
Connections (score out of 10)This is a measure of how we performed when installing private gas connections for homes or businesses. Our score of 9.05 out of 10 is ahead of our target and in line with our outperformance throughout RIIO GD1. We’ve transformed our connections service in recent years, to make it far more customer focused, and this is reflected in the strong score. |
8.4 | Ahead | |
Complaints metricWe receive an overall complaints score each year, based on four different elements: the percentage of complaints unresolved after one working day; percentage of complaints unresolved after 31 working days; percentage of repeat complaints and the number of Energy Ombudsman decisions that have gone against us. |
11.6 | Ahead |
