After nearly five years of holding Telecom Plus we have a paper capital gain of around 25pc, plus 268p in dividends per share that double our return, and last week’s interim results offer plenty of scope for believing the next five years could offer a similarly pleasing bounty – if not more.

Britain’s energy market can be held up as an example of how price caps can create as many problems as they purport to solve but Telecom Plus looks capable of coming out of the mess smelling of roses.

The “multi-utility”, which provides energy, broadband, mobile and insurance to households and small businesses, is profitable and cash generative and has limited debt, so it is no surprise to see the firm attract both new partners who can sell its wares and new customers who are looking for a reliable supplier.

In the first half of the FTSE 250 firm’s fiscal year customer numbers rose slightly to 660,700 and the total number of services supplied to just over 2m, as customers continued to take more than one service from it.

Thanks to the chaos in the energy market Telecom Plus added another 15,000 customers in October alone and management is now looking forward to double-digit percentage growth in the second half of the year as more rivals go broke and leave consumers looking for a more reliable service elsewhere.

Churn is already low – just 0.7pc of energy customers left for another provider in the first half – and going lower thanks to the collapse of those rivals that were offering energy prices that proved to be unsustainable. Existing customers are staying put and new ones are joining.
