About radiator replacement in Plymouth
Plymouth is a large city of around 264,000 in Devon. 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 PL1, PL2, PL4 tend to be quicker jobs with standardised fittings. Local trade prices sit in the same ballpark as the UK average, with Devon firms quoting close to national rates.
Bristol and Bath run hot. Step outside them and into Devon, Cornwall or rural Somerset and the supply thins out fast, especially for specialist trades like heat pumps or unvented cylinders. Lead times get longer the further west you go, and most firms will add travel if you're past the nearest big town.
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.
