Labour charges are simple and transparent. We do not have any hidden charges, but there is a minimum charge of one hour per job. Thereafter work is charged to the nearest 15 minutes. Hourly rates vary according to the time slot – please call for details.

  • Appointments will be made to achieve the maximum convenience possible for our clients.
  • When a visit is made during the higher rate periods we will attempt to resolve the problem fully and swiftly. Should significantly more time be required we will ‘make safe’ to prevent further damage and return to complete the work at regular day rates.
  • Customers will not be charged for travel to the job except for jobs over 15 miles from BS6. There will be a mileage charge over and above 30 miles each day.
  • Materials supplied by MostynCooper will be charged at cost plus handling (unless otherwise agreed).
  • Payment is due in full on completion of the work unless otherwise agreed in advance.
  • Invoices are due on receipt.
  • Payment can be made by BACS, Debit and Credit card or Cheque (payable to MostynCooper).
  • MostynCooper never knowingly overcharges its customers for heating or plumbing services. We aim to build relationships on trust and correct charging is vital to this.
  • Commercial terms may vary from this and are available on request.

Our success depends on your satisfaction. All our plumbing and heating engineers are fully qualified, insured and where necessary accredited by Gas Safe and other trade bodies.

All materials and products are covered by full manufacturers’ warranties and our labour is backed by our own 12 month guarantee of workmanship (unless otherwise stated). All our terms and conditions are available on request or by clicking here.

Any defects arising from faulty installation or repair work that occur within the guarantee period are treated as a priority and will be dealt with at the customer’s earliest possible convenience.
