I'm privately renting a flat and last week my boiler broke leaving me with no hot water and no heating. I let the landlord know on Thursday 1/11/12 and he booked a plumber who came on Monday 5/11/12. The plumber filled out a gas safety certificate and said that the boiler needs a new pressure switch. The landlord says he has ordered the pressure switch and will have it fitted towards the end of next week. Would it be unreasonable to ask to have it done sooner as by then I will have been without either heating or hot water for 2 weeks. I've had to wash by boiling the kettle and filling up the sink but it's getting cold and I have long hair that's very difficult to wash in the sink.
