Did you know that, with effect from 1st April 2002, the installation of a replacement window, roof light, roof window or specified type of glazed door must either have Building Regulations approval or be carried out (and certified) by an installer registered with the Glass and Glazing Federation? If you didn't, and you carry out any of these works after that date, then when you come to sell you will find that you have a problem! The lawyer acting for any purchaser will likely query the fact that you have not obtained the required permission. As the property will not comply with mortgage lenders' requirements, any attempt to sell it will stall until the necessary consents have been granted.

There are several reasons for these new regulations:

• To meet the increasingly harsh insulation standards of national and international energy-saving targets
• To regulate levels of ventilation
• To ensure escape in case of fire
• To prevent people from falling.

Building Regulations approval is NOT usually necessary for repair work such as replacement glazing or replacing rotten frame members and even if it is necessary, exemption can still be gained if the work is carried out by an "approved installer" who is a member of FENSA ("Fenestration Self-Assessment Scheme"). This is a scheme that has been approved by the Secretary of State to monitor the quality of installers' work.

Even if local authority approval is not necessary under Building Regulations, you may still require Planning Permission or Listed Building consent. Special rules also apply if you live in a Conservation Area.

So before you sign a contract to buy double-glazing, check whether the company is able to self-certify. If it is not, then you should apply to the Local Authority for Building Regulations approval and this will involve the inevitable "fee". Consent will also be required if you decide to install replacement windows and doors yourself as a DIY project.
