Manchester is among the cities where boiler engineers are most in demand, according to new research.
As the mercury drops, gas specialists are hot property in cities up and down England.
Locations including Birmingham, Hull and Coventry also face a shortage of skilled tradespeople, according to the research by leading training company Engineering Real Results.
Managing director Ricky Sharma said: “Skilled tradespeople are in short supply all across the UK.
“At this time of year, when temperatures start to drop and homeowners need help with their boilers and heating systems, it serves as an even greater reminder that as a country we need to invest in filling the skills gap.”
The data was compiled by analysing the number of active jobs on leading online recruitment sites, such as Reed and TotalJobs.
At the top of the list were Birmingham and Hull, closely followed by Manchester.
Coventry was the fourth, while boiler experts are also in demand in Nottingham, Newcastle and Milton Keynes.
Gas engineers specialise in installing, repairing and maintaining gas appliances and heating systems.
According to the National Careers Service they can expect to earn up to £38,000 a year depending on experience.
Mr Sharma added: “We are also seeing a high number of job vacancies for electricians and plumbers.
“Across the construction industry there is a growing demand for skills but unfortunately a shortage of the correct qualifications.
“These are careers which will always be in demand, especially if the government is to meet their ambitious house-building targets.
“We need to be focusing on bridging the skills gap as a matter of urgency to ensure the UK has enough tradespeople to meet the demand.”
