How to Reconnect with Old UK Colleagues (2026)

Why this matters

UK professional networks decay structurally without maintenance. Most candidates have 20-50 ex-colleagues they've lost touch with. Reconnecting reactivates relationships that took years to build, often producing career help years later. The reconnection cost is small (30 minutes for 5-10 messages); the compound is enormous.

Step-by-step

1. 1 List 10-20 ex-colleagues you've lost touch with
2. 2 For each, identify one specific positive memory of working together
3. 3 Send a brief LinkedIn message: 'Realised we hadn't spoken in [time]; remember when we [specific thing]'
4. 4 No ask — just reconnecting
5. 5 If they respond positively, suggest a 15-min catch-up call
6. 6 Add to your quarterly maintenance list afterwards
7. 7 Don't reconnect with everyone simultaneously — 5-10 per month is sustainable

Common mistakes

• ✗Generic 'hope you're well' messages without specific reference
• ✗Asking for help in the first reconnection message
• ✗Reconnecting only when you need something — flags transactional
• ✗Skipping the specific memory anchor — generic messages convert at half the rate
• ✗Not following up to the people who do respond
