By law it is required to have an EPC for every property in the UK whilst renting or selling, they last for 10 years unless any specified work that can affect it is carried out. As a landlords obligation you must supply the EPC free of charge to any prospective tenants and as an agent marketing the property we are breaking the law if we market your property without an EPC. We can be fined. Speak to us and we can recommend an expert.
