How we got a Carshalton CIS electrician £5,200 back across two years
Client M is a self-employed electrician working CIS for contractors across South London and Surrey. He'd had 20% deducted at source for two years and filed basic returns himself without claiming most of his legitimate expenses, leaving substantial refunds unclaimed.
We reconstructed his expenses from bank statements and receipts: van costs (mileage method), tools and test equipment, PPE, materials he supplied, NICEIC registration, phone proportion, and accountancy. We re-filed both years' self-assessments claiming his personal allowance and the full legitimate expenses against the CIS-deducted income.
