About double socket installation in Southampton
Southampton is a large city of around 253,000 in Hampshire. The housing is mostly period cottages, Edwardian villas and 1930s semi-detached housing alongside newer commuter developments. That matters: older properties usually mean more pipework, rewiring and retrofit surprises, while newer builds in districts like SO14, SO15, SO17 tend to be quicker jobs with standardised fittings. Local trade prices sit a little above the UK average, which tracks with Hampshire labour and material costs.
A lot of South East firms work both London and local jobs. Rates usually track London with a small discount, so you're rarely getting a bargain. Peak season runs May to September and good tradespeople can be three to four weeks out. Out of season is the time to price round.
Anything notifiable (new circuits, consumer unit swaps, bathroom zones, EV chargers) falls under Part P and has to go through an NICEIC, NAPIT or ECA registered electrician. Day rates run £200 in the regions up to about £400 in London. If your sparky can't give you a Building Control certificate at the end of a rewire or CU change, walk away.
