Shoring up fence with loose/rotten posts

I’ve got a fence that is 10 posts long, currently leaning (about 20cm at its worst) and flapping in wind. 5 of the posts are still very sturdy when force applied, the other 5 have varying degrees of wobble. Is there a way of fixing without digging out existing posts? I was wondering if I could put a few posts in on opposite side? After reading the costs of getting the posts replaced professionally (£150-250 each) I think it’s a fair bit out our budget just now. Any tips appreciated

"There isn't much you can do about the cost, as it requires digging to a depth of about.1-2 metre, in theory you could install "arms", from the posts, that sit on the ground in your garden, but then you get, obstruction in your garden, what's the issue, is it price per post? If so, why not do a couple at a time? As I said, effectively it's a deep dig followed by concrete to secure it, and that's long lasting, perhaps I could do you a deal depending on location?

However all the temporary solutions wont solve the problem and won't look as good"

"Hi, ideally you would want them replace to guarantee a strong fence. Depending on panels and post price will vary."

"Concrete repair spurs. These are dug in beside the damaged posts and you bolt the old post to the new concrete spur. Really good solid fix and not too expensive to do. Hope this helps. Jon."

"you want the job done properly
either new posts or repair concrete spur posts and coach bolts as long as the leaning posts are timber"

"I’d personally recommend using concrete spur support posts on the other side of the post to try pull it back to where it needs to be, you could also dog around the posts and applying some more post Crete to try and sure the posts up abit more.. are the posts timber or concrete ?"

"£150 to £250 per post seems excessive to me. It appears to me the posts have been set just into the soil and no form of anchor medium such as postcrete has been used. Dig the soil out around one of the posts and see if there is anything holding the posts in place other than the soil around them."

"yes it is possible with the placement of the posts on the other side if the fence is on the back of the house"
