My work is insured and carries a standard two year guarantee on parts and workmanship.  Work that is notifiable to Local Authority Building Control will be processed through NAPIT.

Guarantee. Of course, I would expect any electrical installation work I perform for you to last for decades as I use quality component parts compliant with British or equivalent European standards which I install to BS7671 and to the building regulations, but for reasons of practicality, all my installation work carries a (non insurance backed) two-year goodwill guarantee as standard to give you the peace of mind that in the unlikely event of something going wrong afterwards, it will be put right quickly and without fuss. My two-year guarantee only applies if you pay the related invoice in full within five days of issue. If paid after five days, then a 12-month parts-only guarantee applies instead. If not paid in full then you can expect short shrift if you make a claim.
