Lawrence from J & L Gas & Renewables Limited plumbed and fitted a new garden tap today 8th May. He quoted us a very competitive price, arrived on time, and did a wonderful and very professional job. Everything was left clean and tidy including refitting the drawers into the kitchen sink unit. In addition to an excellent, fast and professional job, Lawrence was kind and very helpful and explained everything to us. I would not hesitate to recommend him and his firm for any plumbing and gas heating work.

Andre and team did a great job with the shed /summerhouse construction, and were very accommodating with the request to build it at short notice ( (within 5 days) and alter the layout of the building to meet our requirements. Also were very friendly and professional. Reasonably priced too. Would recommend.
