Shurgard

First of all don’t get fooled by their offers which they advertise.
The £1 first month rent, only applies to a very limited number of storage units which are not available at %90 of the times.
It goes the same with the «%50 off» offer as well.
You also need to pay £30 for the lock.
They say you can use your own lock but in fact they designed the doors in a way that you can only use the locks they offer themselves.
They say there is no minimum stay, yet again they set their «Terms and conditions» in a way that forces you to rent the storage for at least 1 month, then they offer a refund for maximum of 2 weeks.
For instant if you need a storage for 1 week only, you have to pay for the whole month then you get a refund back for only 2 weeks.
Speaking of refunds, they say it takes 5 – 7 working days to reach to your account. In my case was 18 days.
Also when I received the refund it was £3 less than the amount I suppose to receive.
Storage hallways smells like someone urinated there. (literally)
Also there is no 24hr access.
Very rude and irresponsible staff. Insurance is mandatory as well regarding to their few times security breaches, which is another extra non-​refundable amount you have to pay.
Security is horrendous. I highly recommend you check out the BBC’s Watchdog program on this matter:

Rather than further clutter my overcrowded flat, I decided to put some bits and pieces into storage.
This branch of Shurgard has recently been upgraded (which is probably why they claim they are in Holland Park — ha ha) and there are only some of the old style cages left. Most units — which are ambitiously referred to as rooms — are boxes of varying sizes with secure metal doors and uniform cylinder locks (paid for as part of the £20 sign-​up fee which is non-​refundable).
It’s all really straight forward and with your keys and code card you have 24 hour access. The rates seem fairly reasonable (I didn’t compare prices of any competitors as this is located more conveniently for me) and discounts apply if you commit yourself for a longer period — at the moment new customers receive the first month’s rent for just £1.
Packing materials are available for sale at the office — while I was here one guy was complaining about the price. Some obvious advice: come prepared — after all, Westfield is in spitting distance.
I was looked after by a lovely guy called Anthony who knew how to handle all types of customers with the highest level of professionalism.
