The cost of a 10-mile taxi ride in Boston could increase to as much as £21 - with extra costs when the price of diesel tops £1.80 a litre.
Lincolnshirelive reports that members of Boston Borough Council's ruling cabinet are set to agree new tariffs for hackney carriages.
It is proposed that under tariff one, the cost of taking a taxi capable of carrying up to four passengers between 7.30am and 11pm would range from £4.80 for one mile to £21 for 10 miles.
The second tariff covering the period between 11pm and 7.30am, Sundays, Bank Holidays, Christmas and New Year is set to be £7.20 for a one-mile trip and £31.50 for 10 miles. The tariff also applies to vehicles carrying five to eight passengers between 7.30am and 11pm.
Changes to the third tariff for larger vehicles between 11pm and 7.30am on Sundays, Bank Holidays and the Christmas and New Year period would be £9.60 for the first mile, with a 10-mile journey costing £42.
In addition, councillors are to consider an additional discretionary fee of 20 pence for each journey when the cost of diesel exceeds £1.80, with a further 20p increase for every 10p rise in the cost of diesel thereafter.
And booking fees are set to increase to a maximum of £8, with the soiling charge going up to a maximum of £100.
The proposed changes comes after Boston Hackney Carriage Association (BHCA) requested a review of the maximum hackney carriage fare structure - the last increase in fares was in April 2018.
The council's regulatory & appeals committee last month recommended the cabinet agree the price rises when it met on July 4.
A report to the cabinet states that councillors previously considered additional relief for hackney carriage firms in the event of fuel costs continuing to increase.
"It was determined that the committee would recommend an additional discretionary fee of 20 pence to be paid for each journey when the cost of diesel exceeds £1.80 with a further 20 pence increase for every respective 10 pence in the cost of diesel thereafter, the report states.
"For example, at the time of writing the regulatory & appeals committee report, the cost of diesel was £1.76 per litre and at the time of writing this report the cost had increased to £1.94 per litre.
This would mean that a hackney carriage fare could be increased by a maximum of 40 pence for each journey."
The report added: "During the meeting, members asked why BHCA had not asked for an increase in tariff 3. BHCA confirmed that, as they do not have any members who would have cause to use tariff 3 it wasn’t a consideration they had taken into account but agreed with the senior licensing officer that an increase in tariff 3 would ensure a fair increase for all."
The recommended option would increase tariff 1 as requested by BHCA, with tariff 2 charges being set at a 50 per cent increase of tariff 1, with tariff 3 charges being a 100 per cent increase of tariff 1.
The report concludes: "It is anticipated that an appropriate increase will maintain a reasonably priced taxi service for members of the public whilst also providing increased income for taxi proprietors and drivers.
"Proprietors or drivers who are opposed to the increase can opt to continue to operate using the existing tariff."
