About oil boiler installation in Worthing
Worthing is a medium town of around 111,000 in West Sussex. The housing is mostly period cottages, Edwardian villas and 1930s semi-detached housing alongside newer commuter developments.

Local trade prices sit a little above the UK average, which tracks with West Sussex 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.
Heating is a regulated trade. Gas Safe for anything gas, OFTEC for oil, HETAS for wood burners and stoves, MCS for heat pumps. The bulk of the price is the engineer's time, roughly £300 to £500 a day in 2025, plus the appliance. A summer quote on the same job is usually 10 to 15 percent less than a winter emergency one, so don't leave an ageing boiler until October.
