We are roughly 60 domestic 40 commercial , years ago I had all my eggs in one basket with doing all my commercial work for one company that was a big mistake as they decided to go with a national company so I lost the contract costing me many thousands of pounds ,it had a big impact on my buisness, however I now have got this contract back due to the poor standard of the work being done but now do commercial work for a number of company’s so if I lost a contract it wouldn’t have such an impact , if there was enough commercial work in my area I would only do that as I much prefer it and it pays better and no chasing smaller payments like domestic
