Having the right qualifications
Some of the most common routes to becoming a loft-conversion specialist are by c ompleting an apprenticeship as a builder, carpenter, or joiner. Once you've mastered the basic skills, the specifics of loft conversion techniques are then a case of upskilling.
Apprenticeships are a good place to start in any hands-on career.
Depending on the type of loft conversion work that needs doing, the following qualifications will probably be useful:
Level 2 or 3 Diploma in Bench Joinery
Level 2 or 3 Diploma in Site Carpentry
NVQ Level 1 Certificate in Construction Skills
Equally, national industry bodies offer alternative ways of gaining qualifications. These enable those with experience in a similar trade - such as builders and carpenters - to become qualified loft-conversion specialists.
Short courses from professional bodies
The following bodies provide succinct training courses to improve your understanding. They also formally recognise you as a professional loft converter.
What's more, industry bodies offer accredited memberships to exceptional loft converters. This will highlight your competence and help to impress potential clients.
The importance of having a CSCS card
Loft converters are expected to have completed the Construction Skills Certification Scheme (CSCS). Having a CSCS card isn't a legal requirement, but it will give you the credentials to operate on construction sites. This, in turn, helps to ensure you don’t lose out on any potential work.
