Welcome to the HEXUS DiY forum, a place to post ideas, request for help or general DiY chit-chat.
However, while DiY on your house may save you money, you should be aware of your own limitations, and remember that some building and DiY work is regulated. Work involving gas must be approved and commissioned by a registered gas installer, major electrical work must conform to part P of the building regulations, and major construction work may require planning permission and/or compliance with building control regulations.
If in doubt seek advice from a qualified professional, such as a construction engineer, architect or builder.
