Your home 159 has been installed by a professional. You should keep this safe, as you may need it should you want to sell your home in the future. See the Gas Safe Register website: www.gassaferegister.co.uk. Additionally, members of the Heating and Ventilating Contractors' Association can advise on all types of central heating. All domestic installation work done by member companies is covered by a free three-year guarantee. See the Heating and Ventilating Contractors' Association website: www.hvca.org.uk. When looking for contractors to install your equipment, an important point to note is that new legislation places tighter controls on the standard of electrical and other installation work in households across England and Wales. It is now a legal requirement for electricians as well as kitchen, bathroom and gas installers to comply with Part P of the Building Regulations. You would therefore be well advised to check that any contractor you propose using is enrolled with the relevant inspection council or is a member of the relevant trade association. Electricians should be approved by the NICEIC. All approved contractors are covered for technical work by the NICEIC Complaints Procedure and
