Hatfield is a small town of around 39,000 in Hertfordshire. The housing is mostly a mix of Victorian terraces, inter-war semi-detached housing and modern new-build estates. That matters: older properties usually mean more pipework, rewiring and retrofit surprises, while newer builds in districts like AL9, AL10 tend to be quicker jobs with standardised fittings. Local trade prices sit a little above the UK average, which tracks with Hertfordshire labour and material costs.
