You've built up equity in your home over years of mortgage payments, and now you want to put some of it to work, without the whole thing feeling like a leap into the unknown. This guide walks you through getting a HELOC from start to finish, in order. A HELOC is a home equity line of credit: a flexible line of credit secured against your home that lets you borrow up to an agreed limit, draw what you need, repay it, and draw again. The process runs in four stages: you complete the 10 minute online application, share your documents and pass affordability checks, have your property valued and receive a formal offer, then complete the legal steps and draw down your funds. Below, each stage is set out in plain terms, with what happens, what we check, and roughly how long it takes.
What's a HELOC, and could you get one?
A HELOC lets you borrow against the equity in your home, up to a set limit, and you pay interest, only on what you actually draw. Equity is the share of your home you own outright: your property's value minus what's left on your mortgage. If your home is worth £400,000 and your mortgage balance is £200,000, you have £200,000 of equity.
The key thing to understand is that a HELOC is a second charge. That means it sits on top of your existing mortgage rather than replacing it, so you can access your equity without touching your current mortgage rate or repayments. If you're on a low fixed rate you'd rather not disturb, that matters. It's also what makes a HELOC different from a remortgage, and if you're weighing the two, our guide to a HELOC versus remortgaging sets out where each one fits.
Could you get one? As a rough starting point, you'll usually need to own a home in the UK with a decent amount of equity in it, a reasonable credit history, and enough income to comfortably cover the repayments. The exact criteria depend on your circumstances and are subject to lender checks. If HELOCs are new to you, our explainers on what a HELOC is and how a HELOC works cover the basics in more depth, and our list of reasons homeowners consider one may help you judge whether it suits your plans.
Step 1: get a quote online and complete the application
Start with a quick online quote. We’ll ask about you, your property, your income and your regular expenses, then show you an estimate of how much you could borrow and what it might cost. Getting this quick quote won’t affect your credit score.
If the figures look right, you can complete the full application in around 10 minutes. Your quote is only an estimate at this stage; we’ll confirm the details after reviewing your documents, checking affordability and valuing your home.
Step 2: sharing your documents and affordability checks
Once you decide to proceed, we ask for documents that prove what you told us in the quote, and we run a full affordability check. An affordability assessment simply means we look at your income and spending to make sure the repayments would sit comfortably within your budget, now and if rates were to change.
The documents we'll typically ask for include:
- Payslips from the last three months
- Bank statements for the last three months, from all accounts held in your name
- Your latest mortgage statement, or your mortgage account number
- ID verification, which you complete through a secure link
- Bank details for the account you'd like the funds paid into
If you're borrowing for home improvements, we may also ask for a builder's quotation, plus planning permission where it's needed. If any of the borrowing is going towards clearing other debts, we'll ask you to complete a debt consolidation form confirming the balances involved.
This is also the point where we run a full credit check, which does leave a mark on your credit file. There's nothing to catch you out here. We're checking the same things any responsible lender would: that the borrowing is affordable, that your credit history stacks up, and that the property is suitable security. Send the documents over promptly and this stage moves faster.
Step 3: your property valuation and formal offer
Before we can make a formal offer, we need to know what your home is actually worth. So the next step is a valuation. This confirms your property's current market value, which in turn confirms how much equity you have and how much you can borrow against it.
Depending on your property and circumstances, the valuation may be done using data we already hold and recent local sales, or it may need a surveyor to visit in person. Where a visit is needed, we'll arrange a time that works for you.
Once the valuation is in and the checks are complete, our underwriting team makes its decision. Underwriting is the final review, where a person weighs up everything together: your income, your credit history, the affordability figures, and the valuation. If everything lines up, you receive a formal offer. This sets out your credit limit, the interest rate, and the terms in full. Read it carefully, because this is the document that tells you exactly what you're agreeing to. Take your time over it, and ask us anything that isn't clear before you sign.
Step 4: legal steps and drawing down your funds
After you accept the offer, there are some legal steps to complete before any money moves. Because a HELOC is secured against your home as a second charge, it has to be formally registered against your property. This is standard for any secured borrowing and it's handled for you, though you'll need to sign the paperwork and provide any final confirmations we ask for.
Once those steps are done, your line of credit is open and ready. Now the flexible part begins. Drawing down simply means taking money from your credit limit. You don't have to take the full amount, and you don't have to take it all at once. You draw what you need, when you need it, and the funds go to your nominated bank account.
Here's what makes a HELOC different from a standard loan. You pay interest, only on what you've actually drawn, not on your whole limit. During the first two to five years, the flexible period, you can draw, repay, and draw again as many times as you like, up to your limit. So if you draw £20,000 for a kitchen, repay some of it over a few months, then need £5,000 later for something else, the line is there. This is the point where a HELOC starts to earn its place, and our guide to the top ways to use a HELOC covers where it works best.
How repayments work once you're funded
Your repayments are based on what you've drawn, not your full credit limit. If you've drawn nothing, you've nothing to repay. Draw £30,000 and your repayments are calculated on that £30,000, plus interest, not on the larger amount you were approved for.
A HELOC repayment term can run from 5 to 30 years. During the 2-5 year flexible drawdown period, you have the freedom to draw and repay as your needs change, paying interest on the outstanding balance. After the flexible drawdown period ends, you repay what you still owe over the remaining term, in the usual way.
One point to be clear about: HELOC interest rates can be variable, which means your monthly payment can go up or down if the rate changes. Before you draw, it's worth being sure you could still afford the repayments if rates rose. The exact figures depend on the amount you draw, your rate, and your term, all of which will be set out in your offer. Your home is used as security throughout, so keeping up your repayments is what protects it.

Frequently Asked Questions
Do HELOCs exist in the UK?
Yes. HELOCs began in the United States, but they are now available to UK homeowners. Selina Finance was the first regulated provider to offer one in the UK. A UK HELOC works on the same principle as its US counterpart, a line of credit secured against your home, but it operates under UK rules and regulation.
What's the difference between a HELOC and a Homeowner loan?
A Homeowner loan gives you a single lump sum that you repay over a fixed term, with interest charged on the whole amount from day one. A HELOC gives you a credit limit you can draw from as needed, and you pay interest, only on what you've actually drawn. In short, a Homeowner loan is one fixed sum; a HELOC is a flexible credit line.
Why can a HELOC be considered risky, and could I lose my home?
A HELOC is secured against your home, which means your property is at risk if you fail to keep up the repayments. That's the core risk with any secured borrowing. Rates can also be variable, so your payments can rise. You reduce the risk by borrowing only what you need, being confident you can afford the repayments even if rates go up, and keeping those repayments up throughout the term.
How much can I borrow with a HELOC?
How much you can borrow depends on the equity in your home, your income, and your credit history. Lenders look at your property's value against what you still owe on your mortgage, this is called your equity, then decide how much of that equity you can borrow against. A quick online quote will give you an indicative figure for your own situation before you apply. At Selina, we do have a borrowing range limit of £5k to £500k.
What will my HELOC repayments look like?
Your repayments are based on the amount you draw, not your full credit limit, plus interest at your rate. Draw nothing and you repay nothing. Because HELOC rates can be variable, your monthly payment can change if the rate does, so it's worth checking you could still afford it if rates rose. Your exact figures will be set out in your formal offer.
Your home may be repossessed if you do not keep up repayments on a mortgage or any other debt secured on it. Think carefully before securing other debts against your home. If you consolidate existing borrowing, you may be extending the term and increasing the total amount you repay.
