Great service. It was difficult to source a plumber at short notice. On that note I would like to thank the professional and efficient service provided by Berkshire Heat Ltd.
Leon was very helpful and provided a very good service. Came on time exactly as they said. Emergency plumber was quick and did a good job. Also polite and business-like.
