BT / Openreach Payslip Explained 2026/27
What Is OCL? Engineer Pay, On-Call & the 10% Pension Match
Last updated: 17 September 2026 · 2026/27 UK tax year
If you're a BT or Openreach engineer, your payslip is full of acronyms and allowances negotiated by the CWU. Here's exactly how your pay, OCL, and massive pension match work.
Openreach Engineer Pay 2026 — What Do You Actually Earn?
Unlike the NHS or Civil Service, BT Group and Openreach salaries are not published in a simple public pay scale. Pay is negotiated annually with the CWU (Communications Workers Union) and varies heavily based on your specific CWU zone, London Weighting, and length of service.
| Role / Experience Level | Estimated Annual Salary (2026) |
|---|---|
| Trainee Engineer (New Start) | ~£22,925 |
| Openreach Engineer (Mid) | ~£35,160 – £35,554 |
| Senior / Experienced Engineer | ~£40,000 – £47,000 |
| London-based Telecoms Engineer | ~£46,759 (Inc. London Weighting) |

BT pays this directly into your pension pot every month. It doesn't come out of your wages!
What Is OCL on My Payslip? On-Call Allowance Decoded
This is the single most common question from new engineers. OCL stands for On-Call Liability.
It is a standby allowance paid to engineers who are scheduled to be "on call" outside of normal working hours. You receive this fixed weekly payment simply for being available, whether you actually get called out or not. It is fully taxable and subject to National Insurance.
If your phone rings and you have to work, you will receive a Call-Out Premium on top of your OCL. Depending on your CWU agreement, this is usually paid at a minimum of 2 hours at an enhanced rate (often time-and-a-third or time-and-a-half).
BTRSS Pension — Why BT Matches Up to 10%
If you joined BT or Openreach after 2018, you will be enrolled in the BTRSS (BT Retirement Saving Scheme), which is a Defined Contribution (DC) pension.
BT offers one of the most generous employer matches in the UK. If you contribute 5% of your salary, BT will match it with a 10% contribution. That means a massive 15% of your salary goes into your pension pot every month, but only 5% comes out of your take-home pay.
Warning: If you opt to contribute less than 5%, BT scales back their match. Don't leave free money on the table!
BTPS Legacy vs BTRSS New Joiners — Two Completely Different Retirements
You may hear older colleagues talking about their "final salary" pension. BT operates the BT Pension Scheme (BTPS), which is a legacy defined benefit scheme. It was closed to new entrants in 2018.
- Pre-2018 Joiners: May be in BTPS Section C. Your retirement income is based on your final salary and years of service, regardless of stock market performance.
- Post-2018 Joiners: Will be in the BTRSS. Your retirement income depends on the size of your investment pot (hence why getting that 10% employer match is crucial).
London Weighting for Openreach Staff
If you work in London or the immediate surrounding areas, you will receive a London Weighting allowance. This is negotiated by the CWU and varies depending on whether you are in Inner London or Outer London.
It is added directly to your gross salary, which means it is fully taxable, subject to NI, and (crucially) counts towards your pension calculations.
