Think of the time when you moved in the property. You probably signed a contract. And in every rental contract there is a clause, saying that the tenant has to take care of the property and clean it regularly, just as if it is his own. And just for insurance, you probably gave to your landlord a deposit, which he has to give you back at the end of your tenancy, BUT if everything is as it was.
So when the time to move out comes, do not rush to leave the place as soon as possible. Look around and check if everything is clean and undamaged. If there is something which you don't like, fix it or clean it. Otherwise you will not receive your rental deposit back. If you don't have the time to clean the place on you own you can use the services of some professional end of tenancy cleaning Clapham company. They will do the work for you and they surely will cost you less than the amount of the rental deposit. Not only this, but they will also do the work better than you will if you clean on your own.
So, if it is time to move out, do not hesitate to use professional end of tenancy cleaning Holborn services. It is better to spend some money, than to lose a lot.
