How calculated prices work
Alternative-brand figures use Chris's matching Baxi installed price, then add or subtract the VAT-inclusive difference between comparable boiler, horizontal-flue and filter supply packages. Calculated totals are rounded to the nearest £10.
Labour, the RF thermostat, chemical treatment, certification and ordinary installation materials stay the same. Merchant prices can change, so every calculated comparison is checked again in the written quotation.
