Data Engineer Salary in Swansea — 2026 ranges

How Swansea compares to other UK cities for data engineers

Swansea pay sits roughly 10-15% below the UK median for most office-based roles, with a full-time median around £29,000-£31,000 in 2026 against a UK figure nearer £37,000. The DVLA pulls the upper distribution materially higher because Civil Service Digital roles benchmark against UK national rates: software engineers at DVLA Digital typically £45,000-£70,000, senior developers and tech leads £70,000-£95,000, with cyber-security and data specialists £55,000-£85,000 — well above general Swansea tech rates. Tata Steel UK pays at sector benchmark rates: chartered process and electrical engineers typically £52,000-£78,000, senior project managers on the electric-arc transition programme £70,000-£100,000. Welsh Government and council roles pay at standard public-sector grades. NHS Agenda for Change applies nationally. Swansea University runs standard academic-pay-spine rates with research-grant uplifts. Admiral's Swansea office pays at insurance-sector benchmarks broadly aligned with Cardiff. Where the market under-pays visibly: senior commercial roles in marketing, sales, and finance, where Swansea runs 15-22% below Cardiff and 25-30% below London. Mainetti UK and BT both pay at standard sector rates. The local salary distribution is tighter than Cardiff because the structural employers are concentrated in the public sector rather than financial services.

Swansea is one of the cheapest UK cities of its size to live in, with housing materially below Cardiff and most of England. A one-bedroom flat in central Swansea or the Uplands typically rents for £550-£750 per month in 2026, around 28-32% of inner-London rates and roughly 70-75% of central Cardiff. Buying is significantly cheaper than Cardiff: average Swansea house prices sit around £180,000-£210,000, with Sketty, Killay, and Mumbles popular family areas and the Mumbles waterfront commanding a premium. Council tax sits broadly at the Welsh average. Public transport within the city is bus-based and reasonable; most residents drive, particularly those commuting to the DVLA at Morriston or to Port Talbot. GWR runs Swansea to Cardiff Central in around 1h and Swansea to London Paddington in around 3h direct, with typical Cardiff season-ticket pricing around £4,500-£5,500. The Gower Peninsula's AONB status gives Swansea a quality-of-life advantage that few comparable cities can match. A mid-career professional on £42,000 in Swansea typically has materially more disposable income than the same role on £48,000 in Cardiff once housing costs are netted off.
