I don't ask for deposits before work begins, nor do I bill for work that isn't yet completed, so any invoice you have received from me should relate to agreed goods and services that have already been supplied. In the unlikely event that any customer believes the service they have received or the materials I've provided in any way fail to match up to the invoice amount, then I would prefer you to contact me and to not pay the invoice until we have come to a mutual resolution.
If you do pay an invoice and believe within 14 days that the amount was unjust or non relatable to the invoice value, then please contact me with your concerns. Workmanship and materials are all covered by my no-quibble 24 month guarantee, and both my internal complaints procedure and that of NICEIC are there to serve you if you feel you've not had the service you deserve.
Unless other terms have been agreed by all parties in writing, payment is required in full upon presentation of an invoice. Where work is staged, such as on larger jobs with first-fix and second-fix elements, each stage will be billed for upon completion with no new work being scheduled until cleared funds have been received in full for the previous completed stage.
In the event that all parties cannot agree on any other satisfactory resolution to a perceived issue with the workmanship or materials as supplied by David Savery Electrical Services Ltd. or one of its subcontractors, then you may be offered a full or partial refund which will be made via the original payment method.
