Great communication from initial phone call through to the actual service of our boiler. Adrian turned up on time and was great at explaining everything. Apparently none of the previous engineers from a big national had ever serviced our Vaillant combi properly. They'd never emptied the condensate trap that was full of gunk and could potentially cause our boiler to breakdown. It was inaccessible due to a pipe being installed in the wrong place by the original engineer, but Adrian managed to get to it and empty it. I'd highly recommend Adrian (and his team) if you need your boiler service, we'll be using them again next time. They also do plumbing work too apparently.
