Harpenden Building Society

Harpenden Building Society is a UK building society that offers savings accounts and cash ISAs to personal savers, alongside mortgage lending to borrowers. Its savings range is built around instant access accounts and cash ISAs, most of which can be opened and run through Harpenden Online, its internet banking service, as well as in branches or by post¹. Its website is www.harpendenbs.co.uk².

For a saver, the practical points are these. Money held in eligible deposits with the Society is protected by the Financial Services Compensation Scheme (FSCS)³, which covers eligible savers up to £120,000 per person⁴. Everyday electronic transfers out of Harpenden savings accounts are free of charge, with a maximum limit of £100,000 for payments made through Harpenden Online⁵. The Society can vary interest rates and withdraw products from sale, so the terms of a particular issue are always the place to check before committing money⁶.

Savings accounts and ISAs at Harpenden Building Society

Harpenden's savings range falls into two broad families: instant access accounts, where money can be withdrawn at any time, and cash ISAs, which hold savings inside the tax-free ISA wrapper. The Society also runs a regular savings account aimed at a specific age group. Each account has its own terms on how it can be opened, how it is operated and how money is paid in and taken out, so the account page on the Society's website is the place to check the details of a particular issue before applying.

The Instant Access Account (Issue 2) can be opened on Harpenden Online via the Society's website, in one of its branches, or by post¹. The Online Instant Access (Issue 3) account sits alongside it in the instant access family, and the Online Single Access (Issue 3) account is another online-operated option⁷. The 18-30 Regular Saver (Issue 1) is different: it can only be opened on Harpenden Online via the website, and is not available to open in branch or by post³. That age-linked name signals who it is designed for, and its terms are on its own product page.

On the ISA side, the Cash ISA (Issue 2) can be opened on Harpenden Online, in a branch or by post⁸, while the Online Single Access ISA (Issue 3) is opened on Harpenden Online via the website at www.harpendenbs.co.uk⁹. ISAs are covered in more detail in our guide to ISAs, and the general workings of savings accounts, including notice periods, fixed terms and how interest is paid, are explained in our guide to savings accounts.

Mortgages: Harpenden as a building society lender

Harpenden is a building society, and building societies exist to take savings deposits and lend them out as mortgages. As a mutual, a building society is owned by its members rather than by outside shareholders, and its lending is funded largely by the money savers place with it. That is the model behind Harpenden's mortgage lending: money placed with the Society by savers is lent on to borrowers buying property.

Because Harpenden publishes its mortgage terms and product details on its own website, anyone considering a mortgage from the Society should read the current terms there, since products and conditions change. Our guide to mortgages explains how mortgage lending works generally, including how deposits, terms and repayment methods affect what a borrower pays, and our guide to buying a home covers the process end to end. If you are comparing lenders, the directory of lenders and card issuers lists the firms operating in the UK market.

Harpenden can change rates and withdraw products

Two rules in Harpenden's account terms matter to every saver, whatever account they hold. First, on interest rates: the Society states plainly that it has the right to vary the rate of interest⁶. Second, on availability: the Society reserves the right to withdraw a product without notice at any time⁶. Both rules are standard across the savings market, but they are worth understanding before money is committed.

What this means in practice is that the rate on a variable rate account is not fixed for the life of the account. If the Society changes it, the account terms will set out how you are told and whether there are any consequences for withdrawing your money in response. A product being withdrawn from sale does not affect an account you have already opened, but it does mean new deposits into that issue may stop being accepted. The safest habit is to note the issue number of your account and check its page on the Society's website, where the current terms and any changes are published.

Fees and charges on Harpenden savings accounts

Harpenden publishes a tariff of charges that relates to all the savings accounts it offers⁵. The headline for most savers is a good one: the electronic transfer of funds by Faster Payment is free⁵, so moving money out of a Harpenden savings account to a current account elsewhere does not cost anything in normal circumstances.

The charges that do exist are for less routine services. A CHAPS transfer, the same-day telegraphic transfer of funds used for large or urgent payments, costs £11.00 per transfer⁵. A stopped cheque costs £10.00 per cheque, and the return of an unpaid cheque costs £5.00 per cheque⁵. The tariff also lists a Data Subject Access Request, the service used when you ask the Society for a copy of the personal information it holds about you⁵. Because the tariff can be updated, check the current version on the Society's website before relying on these figures for a transaction you are about to make.

Banking with Harpenden: branches, Harpenden Online and payments

Harpenden's accounts are operated through three main channels: Harpenden Online, the Society's internet banking service reached via its website; its branches; and post. Which of these you can use depends on the account. The Instant Access Account (Issue 2) can be opened on Harpenden Online, in a branch or by post¹, while the 18-30 Regular Saver (Issue 1) is online-only, and cannot be opened in branch or by post at all³. The Online Single Access ISA (Issue 3) is likewise opened on Harpenden Online via the website⁹.

For getting money out, electronic transfers by Faster Payment are free, subject to the £100,000 maximum limit that applies to Harpenden Online transactions⁵. If you need to move more than that limit, or need the money the same day, a CHAPS transfer at £11.00 is the alternative⁵. Withdrawals can also be made through a branch or by post on accounts that support those channels, following the instructions set out in each account's terms. Before a large transfer, it is worth confirming the daily arrangements with the Society, since the limit applies to Harpenden Online specifically. Our guide to sending money in the UK explains how Faster Payments and CHAPS differ in speed and cost across the market.

Opening an account, including for someone else

Opening a Harpenden account starts with choosing the issue you want and checking its terms on the Society's website. The application route then depends on the account: the Cash ISA (Issue 2) and Instant Access Account (Issue 2) can be opened on Harpenden Online, in a branch or by post⁸, the Online Single Access ISA (Issue 3) is opened on Harpenden Online via www.harpendenbs.co.uk⁹, and the 18-30 Regular Saver (Issue 1) can only be opened on Harpenden Online³. Identity and address checks are part of opening any UK savings account, so have documents to hand.

Opening or running an account for someone else works differently, and this is where Harpenden's rules are strict. The Society states that you cannot open an account within Harpenden Online on behalf of another person⁶. Its online accounts are only available in sole name and are not designed to be operated for someone else⁸. Instead, if you hold a Power of Attorney or a Court of Protection Order and want to open or operate an account on behalf of another person, you need to obtain the Society's form called 'Operating an Account for Someone Else' and return it by post to any branch or to Head Office⁶.

This sits within a wider set of options for letting someone else deal with your money. Most banks, building societies and other account providers allow a third party access to your account, for example with a second card¹⁰. You can also give someone the right to access the money in your account by asking for a 'third-party mandate'¹¹. These arrangements suit different situations, from a temporary spell in hospital to long-term loss of capacity, and our guide to consumer protection explains the safeguards around each.

How to complain to Harpenden Building Society

Harpenden sets out a clear first step for complaints about its savings accounts: contact the Branch Manager at your local branch, or the Savings Operations Manager at Head Office, either by telephone or in writing⁶. The Society also gives an email route for member services at memberservices@harpendenbs.co.uk⁶. Whichever route you use, set out what went wrong, what the account is, and what you would like the Society to do, and keep a copy of what you send.

If Harpenden cannot resolve the matter to your satisfaction, the complaint can be taken to the Financial Ombudsman Service. The ombudsman's process is to talk to your bank or building society first, then fill in its complaint form; a case handler is assigned to investigate and may ask for more information¹². The ombudsman is free to use and looks at the facts independently of the firm. Separately, if a complaint relates to a claim for compensation, the FSCS also accepts complaints over the phone or in writing, or using its contact form¹³.

Your personal data and marketing

Harpenden's account terms include a commitment that many savers will welcome: the Society will not send you marketing material on any other services, and will not share your personal details with any other organisation for marketing purposes, without your consent¹. In practice this means the Society does not pass your details around the wider financial industry for advertising unless you agree to it.

For anything to do with the personal information the Society holds about you, Harpenden asks you to contact its Data Protection Officer in the first instance at privacy@harpendenbs.co.uk⁷. That covers asking what data it holds, requesting a copy of it, and asking for corrections. The Society's tariff of charges lists a Data Subject Access Request among its services⁵, so check with the Society about any current cost before applying. Our guide to consumer protection explains the rights everyone has over their financial data.

FSCS protection for Harpenden savers

Eligible deposits with Harpenden Building Society are protected by the Financial Services Compensation Scheme³. The FSCS is the UK's statutory compensation scheme: if a bank or building society fails, eligible depositors are protected up to £120,000 per person⁴. The limit applies to the total across all accounts you hold with the Society, not to each account separately, so someone with several Harpenden accounts counts them together towards one £120,000.

You can check the Society's entry on the FCA Register, and its status and permissions are also confirmed by its appearance on the Prudential Regulation Authority's list of building societies incorporated in the UK, dated 1 September 2026¹⁴. If a firm were to fail, the FSCS handles claims, and complaints about a claim can be made over the phone or in writing¹³. Our guide to consumer protection sets out how the scheme works across the market.
