ISA Accounts for First Time Buyers in London

How an ISA Can Help You Save a Deposit Faster

Saving a deposit is often the biggest hurdle for a first time buyer in London. An ISA (Individual Savings Account) can make that job easier because your savings can grow tax free, and certain ISA options can add a government bonus towards your first home.

This guide explains the main ISA account benefits for first time buyers, what to watch out for, and how to use ISAs alongside your home buying plan in East London.

Quick definition; what is an ISA “bank account”?

People often say “ISA bank account”. That is basically right for a Cash ISA, which is usually a savings account offered by a bank or building society. Other ISAs, like Stocks and Shares ISAs, are investment accounts rather than standard bank savings accounts.

Key ISA benefits for first time buyers

1) Tax free growth on savings

With an ISA, you do not pay UK tax on interest, dividends, or capital gains inside the account, which helps your deposit grow more efficiently.

2) A generous annual allowance

For the 2025 to 2026 tax year, you can put up to £20,000 into ISAs in total (you can split this across different ISA types).

3) Flexible options depending on your risk and timeline

  • Cash ISA; typically lower risk, savings style

  • Stocks and Shares ISA; higher risk, potential for stronger long term growth
    This matters because a deposit target and moving date should drive the account type you choose.

The Lifetime ISA; the headline option for first time buyers

A Lifetime ISA (LISA) is designed to help you save for either your first home or later life. The big draw is the 25% government bonus.

How the bonus works

  • You can pay in up to £4,000 per tax year into a Lifetime ISA

  • The government adds 25%, up to £1,000 per year

  • The LISA limit forms part of your overall £20,000 ISA allowance

Rules to know before you rely on a LISA

  • You must have had the LISA open for at least 12 months before you can use it for a first home purchase

  • The home must be in the UK, purchased with a mortgage, and cost no more than £450,000

  • If you withdraw for a reason that is not permitted, a 25% withdrawal charge can apply, which can mean you get back less than you put in

Practical takeaway; in East London, where prices can move quickly, you should check the property price cap carefully before committing your deposit strategy to a LISA.

What about the Help to Buy ISA?

Help to Buy ISAs are closed to new applicants (closed on 30 November 2019). If you already have one, you can usually keep paying in until 30 November 2029, with a later deadline to claim the bonus.

For most new first time buyers, the Lifetime ISA is the relevant product to research.

How to choose the right ISA for your deposit

If you want to buy in the next 12 to 24 months

A Cash ISA (or Cash Lifetime ISA, if eligible and the cap works for your target purchase) is often the simpler, lower volatility route.

If your timeline is 5 years plus

A Stocks and Shares ISA or Stocks and Shares Lifetime ISA may be suitable, but investment values can fall as well as rise, so it is not a set and forget option.
