Households are being warned not to attempt DIY repairs on their heating systems this summer.
The warning comes as Dorset residents, looking to save money during the summer months, may be tempted to tackle boiler or oil tank repairs themselves while heating systems are less frequently used.
Trade association OFTEC, a registration scheme for non-gas heating technicians, has outlined five key reasons to leave such work to professionals.
Malcolm Farrow from OFTEC said: "Summer is often the time when households start tackling DIY jobs around the house.

"However, it’s important to remember that boilers and heating systems are burning fuels and can be incredibly dangerous if you aren’t qualified.
"They aren’t designed to be user-serviceable and, whilst we are all trying to save money, cutting corners and attempting fixes yourself will be much more expensive in the long run.
"It’s not worth the risk."
DIY errors can result in carbon monoxide leaks, environmental contamination from oil spills, invalidated warranties, and higher repair or replacement costs.
Unqualified repairs may also reduce the efficiency of heating systems, leading to increased fuel consumption and rising bills.
It is estimated that UK homeowners collectively spend £539 million each year on professional repairs to fix DIY jobs that have gone wrong.
Poorly completed repairs may also complicate property sales, as they can lead to reduced offers or sale delays if additional inspections or remedial work are required.
Mr Farrow said: "OFTEC technicians are regularly inspected to ensure the highest standards of work, and using one gives households peace of mind that their heating system is safe, efficient and ready for when it’s needed again later this year."
While simple tasks like bleeding radiators or adjusting timers can be carried out by homeowners, OFTEC stresses that any servicing or repairs should be left to qualified technicians.
This means using GasSafe-registered technicians for mains gas systems, or OFTEC-registered technicians for oil and solid fuel systems.
Inappropriate DIY attempts can make minor problems much worse, turning what may seem like a small fix into a major and costly issue, especially when the heating is turned back on in colder months.
OFTEC urges Dorset residents to prioritise safety and long-term savings by hiring certified professionals for any heating system repairs or servicing.
