The savings should help, but you’ll need to explain the provenance of the funds in your savings account, otherwise it will appear that you are using a strategy referred to on this forum as ‘funds parking’.

However, just having savings back home may not be viewed as sufficient to demonstrate a strong intention to leave the U.K. You should also consider reducing the intended length of stay - understandably because of the cost, distance etc you want to spend as much time as possible in the U.K. but a shorter stay is likely to be more credible from the ECO’s point of view.

• Family Visa: To be eligible you and your partner must intend to live together permanently in the UK after you apply.
