sun those are all basic legal obligations that ALL cleaning business owners must ensure in order to trade legally unless of coursethey use self employed contractors in which case they are morally and ethically obliged to pay around 25% above the min wage to adequately compensate for employment benefits.
We are on the panel of a trade association for domestic cleaning start ups and all of our members are acting responsibly and meeting their obligations as they should - but I have to say i am also aware of other cleaning business owners that do not meet all of these obligations! However that was fortunate for me because i have ended up with some of their staff (without poaching I hasten to add) who responded to my job ad for a better rate of pay and fair conditions.
The two main business models to consider are:
Private company - usually have employes staff, fully managed by the business owners and fully equipped to do the job.
Agency - just act as a match-maker for self employed cleaning operatives and clients. Cheaper than the fully-managed option above obviously but no real management or equipment supplied and a 'hands off' approach to the staff. The management is client driven in this case and this is why it costs less to run.
Neither model is wrong when implemented correctly and ethically, there is a relevant market for either and high demand for each model, some services are a mix of both, which ca still be done correctly.
Obviously when hiring and paying for a company - the most obvious benefit is the management of staff which is definitely (and notoriously) the most difficult part. Even with the agency model you can ask for a replacement if your cleaner is not a good match.
The crucial thing about choosing is to find a good match for your own needs. Get a few quotes in and see who is offering more or less what you need personally and whether the service level they describe is the right one for you. Every client is different and every service is different. There's always more than enough work for every service to enjoy healthy growth and enough services around to choose a great match for yourself. If you do a bit of homework first, chances are you'll enjoy a great and long-term relationship.
