Hi guys I’m going to hospital for surgery and was wondering if anyone knows how likely is it to contract coronavirus ?

Depends on whether or not there are any active cases at the hospital in question

The  hospital  will have implemented  all  sorts  of  infection  control measures to  ensure the  safety of  their  staff and the patients.

 My common sense and medical background tells me you're actually quite safe.  Much of the building is sanitized daily.  patients are screened and tested for Covid 19 prior to entering the hospital.  And once you're in-room, no one is allowed to visit at the moment to lesson your chances of contracting CovID  Contagions are separated from   non-contagions. 

If there are alot of people with corona virus at the hospital then your chance of catching it is high. It can circulate in the air system and spread throughout the hospital. Also remember though that most people who get it do not even have symptoms. So even if you get it you probably won't know it. 

- Wear the mask they give you whenever you're not alone in a closed room that nobody's been in for several minutes.

- Clean the bedrails, call-bell remote, and other surfaces that you might touch. If they'll let you, bring a container of disinfecting wipes so you can clean things yourself.

- Sanitize your hands whenever you touch any surface that could be contaminated. Wash when you can, but if you're stuck in bed use an ethanol based hand sanitizer. Again, bring a bottle of your own because you won't be able to rely on staff to come clean your hands every time you want.

The government says masks are ineffective. That's not what nurses say. Nurses at the UCI/Orange County Medical Center can't strike during the day or patients will die. So they strike at night, carrying signs asking for more masks. Governor Newsome is taking flack for paying $2/ mask (these are N95 masks that block 95% of 0.3 micron particles). The going price is less than a dollar, but that increased due to bidding from other hospitals for rare and extinct items necessary to keep patients and hospital workers safe. This is why Governor Newsome was willing to pay more, with assured delivery (which didn't get delivered on time due to red tape with approvals). In your case, in the UK, the situation is slightly different, but many factors are the same. Thus, each region has different statistics, and it is impossible to predict the odds of catching COVID. You are weakened by surgery, so more apt to succumb. It boils down to whether or not the surgery is mandatory or could be put off. Catching COVID is not an instant death sentence. The statistics are impossible to state, but I'll try to state them anyway. In Los Angeles County, roughly1 person out of 500 officially has COVID (or had it), based on nose swabs. That number is known (by blood virology reports looking for antibodies) to be false. It is estimated that at least 10 times as many people have COVID or had it (roughly 1 out of 50 people in Los Angeles County). Out of 27,000 known cases of COVID in Los Angeles County, roughly 5% died (roughly 1,350 died), but some of those might be from the undiagnosed group. Assuming that 5% die, you likely would survive COVID even if you caught it. The numbers are bleak, because it stands to reason that if a hundred people shop for food at a store, one of them might have COVID and might have polluted the products and the air.

They keep it at hospital, you should get some.

It's actually very likely.  I'm so sorry.

Normal wards are well away from the critical care units, there is no cross staffing, so you will be fine. Most probably safer than going to Tesco.

Speak to the Hospital about your concern, your be well away from anybody

being treated for coronavirus.
