Serviced my boiler - I cannot comment on the quality as I did not have the Which? checklist to hand. However - rather than getting steps from his van he knelled on my kitchen sink with his boots in the basin and bending the sink, to get access to the boiler. I find this totally inappropriate. Also he gave me just the combustion analysis result but no other emission results despite me asking. The engineer used a brush to clean my boiler (rather than a vacuum cleaner) and the dust spread into my kitchen. The impression I have is that - though they probably own a step ladder and a vacuum cleaner - on this occasion the engineer could not be bothered to bring them into my house. Also left a pile of rubbish.The cost was £70 + VAT which is low for the area, But I do not consider that good value and would rather pay a bit more for a better service. Another firm who I will not ask to do any work for me again.
