Not in the UK they don’t.
Practices are run as businesses but hold one contract only, with the NHS. They get a certain amount per patient registered with them, per year, then extra pots of money depending what they do or offer as additional services.
Out of their pot of money they pay rent/mortgage for the property, all bills, all salaries, all consumables, pension contributions, sick pay, costs incurred by referrals and tests. Cleaning, sterilising services, all supplies, maintenance, some vaccinations, some medications used within the surgery eg emergency drugs, medical equipment.
It’s not a business like a normal business with shareholders etc.
And very few GPs will have salaries of £110k, and definitely not salaried GPs.
