When our boiler was serviced the plumber advised me to have the radiators flushed through as the boiler was 'kettling' which I didn't understand as not had radiators before but he told me what had to be done. He arranged for a quote to be sent to me and advised to have it done in the warmer weather as the heating would be off all day. The plumber that came to do the job was efficient, to the point of putting on slip-on covers on his work boots every time he came in the house. It was an all day job, he had to go in the roof etc. I had no idea it was such a big job (a woman of 78 I thought he attached a hose to the radiator and had a bucket to catch the water) My son had helped me move my blanket ottoman from the radiator and the plumber helped me put it back. The quote mentioned problems that could occur but there were no problems and the bungalow was left all okay when he had finished. He did say that when we had the new boiler - 2007 and not fitted by Simon Barker the plumber should have done the radiators then but from the mess he got out it was obvious it wasn't, and I would have remembered it anyway. I'm more than satisfied with the job and would recommend Simon Barker Plumbing and Heating to anyone.
