Ground anchors: recommendations and London installers?

[Londoner2015]

I will soon be moving to a property with a small driveway, and will want to install a ground anchor to secure my bike with my Pragmasis chain.

What anchor would you recommend? I know of these:
https://www.yanchor.com/fittingt.html
https://securityforbikes.com/torc-ground-anchor.php
https://biketrac.co.uk/hard-security/
The Y Anchor seems the most promising, but also the hardest to install - not sure if it can be installed on any driveway tbh.

Can you recommend any installer in South London (Wandsworth)?
Someone told me about this guy: https://www.yanchor.com/fittingt.html
Or maybe just any builder?

Finally, has any of you installed an anchor in a rented property? Most landlords would want the property to be returned the way it was found, and would want me to remove the anchor. Unless they don't notice it at all and the yanchor is probably the most discreet. Thoughts?

Thanks!

and the bit.

And 1 hour of your time.

Cheaper than 'some guy' I would guess.

The video on Pragmasis site explains all.

and
"Can it be moved?
The Torc Ground Anchor is designed for permanent fitting, and so is really difficult to move once it has been fitted. So please, don't fit it in the wrong place!

If you have to remove it, e.g. when moving house and the new owner doesn't see the merits of having an anchor available, it can be removed by cutting it out of the concrete. This will not be a quick process but if it is done carefully, the body of the anchor can be recovered and installed at a new location. Contact us for a new fitting kit. The cleanest way to cut it out is generally with the aid of a large (9") angle grinder with a concrete-cutting disc. This is a dangerous tool and should only be used by an experienced operator.

We have recently launched the Double Doofer - a new removable ground anchor. This may be a good option for you if you know you will be moving house or needing to move a ground anchor!"

Even Bodyform could follow those directions.

And owning an SDS drilling machine is high on Man Points too.

If you do install it, the biggest mistake people make with resin capsules is not cleaning the hole out properly. A bottle brush costs a quid or so. Otherwise, the resin bonds to the dust, not the concrete around the hole.

We use these a lot in Climbing and Caving, it's a touch more difficult to clean out the holes when you're hanging 100ft over fuck all, but it's still the most important thing to do with them.

Clean it out (At home, vacuum and bottle brush will work well), and it isn't coming out again without a lot of noise and dust.

Otherwise, make sure it's the proper depth, insulating tape on the bit works well.

Concrete drive? Sink the Y a little too much and refill with concrete when leaving.

Otherwise, ask landlord.

What is the drive? concrete or tar?

If concrete you can use bolt type like the torq, also if you have any walls nearby.

If tar you'll probably need an in anchor like the Y so you can bury it and fill with concrete.

I ended up with one of these

took about an hour to install, hammer drill into tar, dig out a bit, mix concrete and install
