There are no rules on who could be a guarantor. In practice, potential guarantors are more likely to be accepted if they are accepted: even if you make sure the other guarantors have registered, it is always possible that your co-guarantors “disappear”. An owner does not have to act against all guarantors, but may choose to sue the guarantors most likely to pay. So even if there are other guarantors, you can make yourself responsible for the total amount of all debts. It depends on what the guarantee agreement says or what is agreed orally. Holme v Brunskill (1878) 3 QBD 495 is the originator of the rule that would exempt guarantors from deviations in the creditor-debtor agreement; a change in the agreement may result in a change in risk, as the surety has never agreed to guarantee the new risk. Cotton LJ`s decision explains this reasoning: “If there is an agreement between the contracting entities regarding the guaranteed contract, the guarantee should be consulted and that, if it did not accept the amendment… He`s released. In North Shore/Anstead Holdings (see above), it was found that the amendments to the underlying agreement were an objective fact. the Tribunal found that an amendment had been made, although both parties testified the opposite of the agreement. It may be possible to negotiate a change to a warranty agreement with the owner. This would ensure that the liability of the deposit is limited to your rent or damage that you have caused.
The law requires that a guarantee agreement be concluded in writing. The agreement defines the legal obligations of the surety. The guarantee agreements provided for the money may constitute insurance which is an activity regulated by the ACF. In addition to collateral for their assets, they can also help guarantors create jobs and secure passport documents. In these situations, guarantors certify that they personally know the applicants and confirm their identity by confirming photo ID cards. If you share the accommodation with other tenants as part of a rental agreement, i.e. a common rent, it is customary that the guarantee applies to the entire rent, not just your share. The Rental Costs Act 2019 applies to guarantors of leases.
 The interest rate on unpaid rents is thus capped at 3 per cent above the Bank of England`s base rate.  It is always best to carefully review each warranty contract so that the surety knows how and when its liability ends.
