In British Gas Energy, we continue to invest in strengthening our operational foundations to drive innovation, retention and better customer outcomes in order to underpin long-term profit sustainability. The number of residential customers remained broadly flat over the year, as price competition remained low in the market and suppliers competed more on service and brand. The number of small business customer sites increased by 15% in the year. We saw lower complaints and a higher NPS, reflecting our conscious decision to invest in customer service.

In British Gas Services & Solutions we have significantly improved our operations, as we look to stabilise our core activity of contract service and repair, whilst driving growth in on-demand and heating installs. Operational metrics continued to improve over the year, including a halving of job reschedule rates to 3%. This improved operational performance underpinned improved customer satisfaction, which was reflected in lower complaints and higher engineer NPS. Our improved operational performance and increased engineer capacity means we can now better target the significant opportunity that exists in the on-demand and heating installation markets.
