I have to replace a boiler in a guesthouse with 7 rooms upstairs and 5 downstairs. The current wall mounted boiler, a Potterton, has done the job well but is now quite old and I will replace it with a similar one. The plumber who checked it recently (and unfortunately is not available to replace it) said it would cost about £1300 to do the job. Can anyone advise me if this is accurate and what I should expect to pay?
Many thanks
