Many jobs only require a single plumber, but larger jobs may need two. If so, you will be required to pay additional fees to cover the labour costs of both technicians.
Callout fees differ, but you can expect to pay roughly double the standard hourly rate. However, ask your plumber what this fee includes; some include one hour of labour.
As you might anticipate, the standard rate for an emergency plumber is higher than the average rate. This is because the plumber may be required to arrive outside normal business hours. The callout fee will be approximately £100, and the hourly rate will likely be higher.
Plumbers must include business costs, travel costs, training costs, insurance costs, and various other costs, such as membership fees to competent member schemes, in their pricing. A plumber's talents and expertise are in high demand, and the price reflects this.
