A boiler engineer works on heating systems including boilers, radiators, and all connected hot and cold water pipework. A gas engineer, on the other hand, can do all these things while also being qualified to work with a system’s gas supply.
Many boiler engineers begin their careers as plumbers before specialising in boiler engineering. Many boiler or heating engineers then decide to become Gas Safe registered. This enables them to work on all parts of a gas-powered or combi heating system and allows them to perform Gas Safe testing and provide certification for tested appliances.
Becoming Gas Safe registered
Gas Safe registered engineers are highly skilled and qualified. To become Gas Safe registered you must:
- Have the required qualifications
- Show evidence that you are competent working with gas
There are several ways to achieve Gas Safe certification. Have a read of our article on joining the Gas Safe register to find out more.
Applying to become Gas Safe registered for the first time costs £354 + VAT. However, The Commission for Employment and Skills found a 43% skilled worker shortage in the gas industry, so your experience will be in high demand and you should quickly make back your initial investment.
Boiler engineers general duties
Boiler engineers are qualified to carry out a wide range of duties. These include:
- Regular boiler servicing
- Installation of new boilers and heating systems
- Maintenance and repair of existing boilers
- Safety testing for boilers and heating systems
As a qualified boiler engineer, you may be required to work in various sectors. Many boiler engineers choose to work in the domestic sector. This involves visiting residential properties and servicing and installing boilers for homeowners.
Domestic boiler engineers may work directly for homeowner customers. They may also work for housing associations or property maintenance companies and landlords.
Some boiler engineers will work predominantly in the commercial or industrial sector. Commercial boiler engineers will work on larger-scale heating systems in shops, offices and leisure centres, for instance.
Industrial boiler engineers will be involved in setting up heating system infrastructure. This may be in large factory settings, warehouses, or as part of mains gas supply for the commercial and residential sectors.

This depends on your experience and qualifications. Apprentice boiler engineers will earn around £6.60 per hour. This increases to around £10.50 for newly qualified boiler engineers or £17 for a more experienced boiler engineer working for a heating and plumbing company.
For self-employed boiler engineers who are registered sole traders, hourly earnings are around £37.50. Meanwhile, running your own boiler engineering limited company can generate an hourly income of around £45.
What is the annual salary for boiler engineers?
The annual salary for boiler engineers varies hugely depending on your experience, qualifications and professional status. While apprentice salaries are generally around £11,880 per year, newly qualified boiler engineers tend to earn around £18,900 and more experienced employees make closer to £30,600.
If you’re self-employed, on the other hand, you’ll have the potential to earn more. Sole traders earn around £67,500 per year on average, while owners of boiler engineering companies can expect to earn around £81,000 per year. Just remember that being self-employed comes with business costs, so you’ll need to factor these in too.
What does a boiler engineer do?
Boiler engineers carry out maintenance, inspection, repair work and installation of boiler equipment and heating systems.
This may involve testing boiler water pressure levels; replacing seals, valves, gauges, and filters; and installing new boilers, radiators, and all associated pipework.
What is the difference between a plumber and heating engineer?
The main difference between a plumber and a heating engineer is that most plumbers don’t hold Gas Safe certification. Conversely, many heating engineers will work solely on boiler installation and repairs and not on other parts of a heating system. In this case, a plumber would be needed to work on any radiators, pipework, and water flow.
