You can do very good work on both commercial and residential. There are pros and cons to both:
Residential:
+ relatively easy to get
+ customers are loyal
+ losing one or two doesn’t have a major impact
+ more flexible than some commercial
+ no compliance issues usually
- can be a pain to deal with (nutters)
- can be fussy about wet weather working
- more admin per £1 of work
- sensitive about who actually does the cleaning
Commercial:
+ Higher value so a good way to get a lot of work quickly
+ not much admin per £1 worked
+ not sensitive about who does the work
+ usually parking is not a problem
+ wet weather working not a problem
- losing one or two contracts can be a bigger impact on your turnover.
- not much loyalty, especially when staff and managers change
- more compliance faff
- harder to get than residential
You have to be careful that any one or two contracts don’t make up too much of your turnover, otherwise losing them could see you in dire straits.
(BTW I’m not talking about shops. I’ve never ever done, nor will I ever do, shops. Most want cleaning weekly which is no good for me at all)
