Posted By Phil A door frame is is not an anchor point, your looking at something that is either specifically fitted for the purpose (eyebolts) or something that is designated as part of the structure (steel beams etc...) Neither is generally found in domestic properties but eyebolts can be fitted. They have to be inspected and tagged every 6 months (LOLER) but would be the homeowners liability Also, it would probably be cheaper to hire out a MEWP or use a scaffold tower (if you have enough access) as to install eyebolts is at least £110 each with a minimum of 1 per window then the costs of the updated tests. It also depends if the wall by the window is structually sound enough to withstand the weight test. Phil

Posted By Stephen Grant Thanks for the responses. Unfortunately all the premises are private homes and our maintenance engineer spends enough time arguing use of his safety footwear so doubt they'd let you instal a fixed anchor point and then accept responsibility for its maintenance. Think we will just have to be inventive. Cheers all.
