Why Choose An Oftec Tec
OFTEC-certified technicians undergo thorough training to ensure they meet industry standards for oil, solid fuel, and renewable heating systems. Each registered technician is issued an official photo ID card, and businesses must have valid public liability insurance when working in customer properties.
In England and Wales, registered technicians can self-certify new installations, eliminating the need for local authority building control checks. A similar scheme is also available in Scotland and the Republic of Ireland.
Hampshire Heating Services
When striving to keep your home warm, especially in such cold winters, you must ensure the broad range of components from the complete heating system are updated and all well-maintained. Our heating services can ensure that all the latest technologies, radiators, and systems inside your home are all fit for regular use and in the best shape, ready for the colder seasons.

Building Regulations
Oil-fired heating, solid fuel, renewable and electrical installations must comply with regional building regulations. In England and Wales, technicians registered with OFTEC have the authority to self-certify their work, eliminating the need for local authority building control involvement.
If you hire a technician who is not part of a ‘competent person’ scheme, you will need to apply for a building control notice and arrange an inspection, which can be both expensive and time-consuming. Additionally, work completed by non-registered individuals is unlikely to come with a warranty.
