Bill validation, reliefs, usage and renewal options · Newcastle and Gateshead
We reviewed 4 bills covering 4 meters (2 half-hourly, 1 non-half-hourly, 1 gas) for Northbank Precision Engineering Ltd, using about 405,000 kWh of electricity a year and 185,000 kWh of gas. We found £247.95 of overcharges on the bills reviewed, which we'll ask the supplier to correct and credit. You may qualify for British Industrial Competitiveness Scheme, worth up to £16,200 a year. Your earliest contract ends on 31 Dec 2026 (83 days away), so renewal needs acting on now. For electricity, the best quote is Supplier E (fixed energy, pass-through non-energy) at about £99,129 a year, £5,371 (5%) less than your current electricity costs. For gas, the best quote is Supplier H Gas (fully fixed) at about £11,784 a year, £2,116 (15%) less than your current gas costs. A 120 kWp solar PV system would generate about 101,300 kWh a year, 93% of it used on site, saving about £22,753 in year one with a payback of 3.1 years after Annual Investment Allowance tax relief. Your half-hourly data shows 46% of electricity is used outside opening hours, which is a quick area to cut costs, and our energy management service can track it meter by meter.
