UK Telecoms business rates: Taxing (and distorting) investment

7 October 2025
Access report

BT’s recent protests against the very high “government-inflicted” costs in the UK versus other countries likely relate to business rates, which are already sky-high by European standards and set to rise further.

The business rates reform has some worthy aims in providing some permanent relief for shops and pubs, but at the expense of discouraging much-needed investment in utilities and telecoms by dramatically inflating the cost.

Telecoms business rates also discourage investment by being hard-to-predict, and are distortive between competitors with dramatic differences in unit costs, with these issues partially addressable through valuation reform.

TAR 2026: You can’t always get what you want…

1 October 2024

In the next fixed line regulatory review—TAR 2026—Ofcom is likely to maintain light regulation on Openreach’s pricing levels, while also maintaining strict restrictions on its pricing structures, which both help altnets. 

On other matters, none of the interested parties (Openreach/altnets/ISPs) look like getting exactly what they want, but by and large the industry will likely get what it needs—regulatory stability with a broadly pro-investment slant.

The next TAR in 2031 is likely to be more dramatic, but by our estimates, even a full return to cost-based charging will not result in significant wholesale price cuts, which is likely to be a relief to longer term investors in BT and the altnets alike.
