By national ratios Delft supports about 210 full-time plumber pros — a large market with room for niche specialists, emergency-only operators and franchises alike. Only 37 % of homes are owner-occupied: landlords, building managers and housing associations place much of the work, often as recurring contracts. The housing stock is old for the country, which pushes repair and replacement demand above the national average.
