Had the survey, a couple of days later there was an opportunity at short notice to have my boiler replaced. A few hours & it was installed. A very professional & thorough service. Arafat’s survey left me feeling confident & with good reason. Konrad a really nice guy did a totally efficient & professional installation. The new boiler is very quiet & already seems to be more economical. Although it’s just been installed I would have no qualms about recommending this company very, very happy!
