Our engineer, Nathan Edwards, carried out our annual boiler service at the end of August. He was excellent. He let us know when he was arriving, he was polite, put on overshoes without being asked, and worked on our boiler efficiently. He explained everything he had done and answered our questions, which was very reassuring. Thank you, Alpha Heating Innovation, for employing skilled engineers and for ensuring they have excellent customer service skills. Nathan is a credit to your organisation.
