Louise France - domestic heating, plumbing and gas engineer
If you would like me to come round, do a survey and give you in depth advice about your requirements, I charge a consultancy fee at the rates below. 
I mostly give estimates rather than quotes, as it isn't always possible to predict the many issues that might arise whilst working in vintage buildings. However, I do promise to make you aware of any problems and to deal with them accordingly.
