The Smart Way to Finance Home Improvements
Keep your savings growing. Pay zero interest. End up with a home worth more. Here’s how the numbers actually work.
Most people approach a significant home improvement the same way: they either dip into their savings to pay cash, or they take out a personal loan and start paying interest. It’s completely understandable — these are the obvious options, and nobody in the home improvement industry tends to point you towards anything else.
But there’s a third way that most people simply haven’t been shown. One that lets you have the improvement you want, pay zero interest, keep your savings fully intact and growing, and potentially end up better off financially than before you started. It sounds too good to be true. The numbers show it isn’t.
In this article we’re going to walk through exactly how it works, and then run three real scenarios — different financial starting points, same £15,000 home improvement — so you can see where you fit.
The Core Idea: Your Savings Are Working. Don’t Fire Them.
Here’s what most people don’t think about when they raid their savings for a home improvement: that money was already doing a job. If it’s in a cash ISA or easy access account, it’s currently earning somewhere around 4–5% per year (check MoneySavingExpert for current best rates). If it’s in a Stocks and Shares ISA tracking a broad index — say, a fund tracking the S&P 500 — the long-term historical average return is around 8–10% per year, though this is variable and not guaranteed.
When you pay cash for a home improvement, you don’t just spend that money — you also lose everything it would have earned while it sat in your account. That’s the hidden cost that never shows up on any invoice.
Now contrast that with borrowing on a 0% purchase credit card. The best cards currently offer up to 25 months with no interest whatsoever. If you can clear the balance within that period, the total cost of your borrowing is precisely zero. You’ve kept your savings earning, paid no interest, and got your home improvement.
The smart play: borrow for free on a 0% card, keep your savings working. The only discipline required is repaying the card within the interest-free window.
The 0% Purchase Card: How It Actually Works
A 0% purchase credit card charges no interest on spending made during the promotional period — typically 20 to 26 months with the best current offers. After that period, the standard rate kicks in (usually 22–25% APR), so the discipline is to clear the balance before it expires.
For a £15,000 home improvement spread over 24 months: that’s £625 per month with zero interest. Compare that to a personal loan at a typical 9.9% APR over five years, which costs around £318 per month — but over 60 months, and with roughly £4,000 in interest on top.

Section 75 protection is a bonus worth having. If you pay any portion of a purchase between £100 and £30,000 on a credit card, Section 75 of the Consumer Credit Act makes your card provider jointly liable with the supplier. Even if you pay just the deposit on the card and the rest by bank transfer, you may have this protection. It costs you nothing and gives you an extra safety net alongside any product warranty.
What If 24 Months Isn’t Enough? The Balance Transfer Play
Not everyone can clear £15,000 within 24 months — and that’s fine. There’s a well-established strategy for this: the balance transfer.
Before your 0% period ends, you transfer the remaining balance to a new 0% balance transfer card. Most balance transfer cards charge a one-off fee of around 3% of the amount moved — so if you have £5,000 remaining, that’s a £150 fee. You then get another stretch of 0% time to clear it.
Total cost of financing £15,000 this way: perhaps £150–£200 in balance transfer fees. Compare that to £4,000+ in interest on a personal loan. The maths is not subtle.
You can repeat this process if needed — lenders don’t prevent it — though it does require some organisation: setting calendar reminders and staying on top of the dates is essential. MoneySavingExpert maintains an up-to-date guide to the best 0% balance transfer cards.
The Property Value Factor: Why the Maths Gets Even Better
So far we’ve talked about the cost side. But a well-chosen home improvement also changes the value side of your balance sheet — and this is where things get genuinely interesting.
Nationwide Building Society research shows that a 10% increase in usable floor area can add up to 5% to a property’s value. Industry commentary from property professionals suggests that a quality covered outdoor structure — one that extends the usable living space of a home year-round — can add between 5% and 15% to a property’s value depending on quality, size, and local market conditions. We explore the research and the numbers in full in our dedicated article: How a Veranda Can Add 5–7% to Your Property Value.
On a £270,000 home — close to the current UK average — a conservative 5% uplift is worth £13,500. That’s not a paper gain you have to wait years for. It’s added to the value of your home the moment the installation is complete. On that basis, a £15,000 veranda effectively costs you £1,500 net in terms of your overall financial position — before you’ve even considered the financing savings or what your preserved savings earn.
This is the combination that makes a quality veranda genuinely unusual in home improvement: the property value uplift offsets most of the purchase cost, the 0% finance means you pay nothing to borrow, and your savings keep growing throughout. We’ll factor all three into the scenarios below.
Three Real Scenarios
Let’s put this into practice. Three people. All want the same thing: a quality covered outdoor space costing £15,000, installed and ready to use. Same home improvement, different financial starting points. We’ll factor in the property value uplift for each — because it applies to everyone equally, regardless of how they finance it.
We’re using a £15,000 veranda as our example throughout — that figure could represent something like a mid-size Haven or Sanctuary with side options, or a larger Pavilion. If you want to see what your specific quote would look like, our online quoter gives you an instant price without needing to speak to anyone first.
Scenario 1: Sarah — “I’ve got £20,000 in savings”
Savings: £20,000 in a Stocks & Shares ISA · Veranda cost: £15,000
Sarah has plenty in savings. Her instinct is to just pay cash — it’s simpler, there’s no borrowing involved, and she can afford it. But let’s look at what actually happens to her money over the next two years under each approach.
Smart Path — 0% Credit Card
Card: £15,000 over 24 months = £625/month
Interest paid: £0
Savings: £20,000 stays invested @ ~8%/yr
After year 1: £21,600
After year 2: £23,328
Savings gained: +£3,328
After 2 years: £23,328 in savings + veranda
Conventional Path — Pay Cash
Savings spent: £15,000
Remaining savings: £5,000
Savings grow @ ~8%/yr on £5k only
After year 1: £5,400
After year 2: £5,832
Savings gained: +£832
After 2 years: £5,832 in savings + veranda
Both paths get Sarah her veranda. But the smart path leaves her with £17,500 more in savings after two years — the £15,000 she didn’t spend, plus around £2,500 more in growth on the full £20k versus just £5k.
And that’s before the property value side. On a £270,000 home, a 5% uplift from the veranda adds approximately £13,500 to the property’s value from day one. So the veranda that cost £15,000 has added £13,500 to her home — a net outlay of just £1,500 in balance sheet terms. Combined with the smart financing, Sarah’s overall financial position has improved substantially. See our article on how a veranda can add value to your property for the full breakdown.
Sarah’s verdict: Smart path + property uplift means she has her veranda, £23,000+ in savings, and a home worth ~£13,500 more. The cash approach costs her nothing in interest but roughly £17,500 in opportunity cost — and she’d have got the same property uplift either way.
Scenario 2: Mark — “I’ve got no savings”
Savings: £0 · Veranda cost: £15,000 · Monthly budget: ~£400
Mark doesn’t have savings to draw on. His options are: use dedicated finance (personal loan), use a 0% credit card and pay it down from income, or wait until he’s saved enough.
Smart Path — 0% Card + Balance Transfer
Month 1–24: £400/month = £9,600 paid
Balance remaining: £5,400
Balance transfer (3% fee): £162
Month 25–38: £400/month clears remainder
Total time: ~38 months
Total cost of financing: £162
Conventional Path — Personal Loan
9.9% APR, 5 years
Monthly payment: ~£318
Total repaid: £19,080
Interest paid: £4,080
Total time: 60 months
Total cost of financing: £4,080
Mark’s monthly outgoing on the 0% card (£400) is actually higher than the loan payment (£318), but he’s done in 38 months vs 60 — and has paid £3,918 less in financing costs.
The property value uplift applies to Mark exactly as it does to Sarah. On day one, his home is worth approximately £13,500 more than it was before — regardless of how he finances the veranda.
Mark’s verdict: 0% card + balance transfer. He gets the same ~£13,500 property uplift, but pays only ~£162 in financing costs versus ~£4,080 on a personal loan. The organisation required — setting reminders, doing the balance transfer — is genuinely worth £3,900 of anyone’s time.
Scenario 3: Emma — “I’ve got some savings, but not quite enough”
Savings: £6,000 in cash ISA · Veranda cost: £15,000
Emma has £6,000 in savings — enough to make a significant dent, but not enough to cover the whole cost. She’s tempted to use the savings and top up with a loan. There are actually two smarter options.
Smart Path A — Keep All Savings, 0% Card
Card: £15,000 over 24 months = £625/month
Savings: £6,000 stays in cash ISA @ ~4.5%
After year 1: £6,270
After year 2: £6,552
Interest earned: +£552
Total cost of financing: £0. Savings preserved.
Smart Path B — Mix: Savings + 0% Card
Put £6,000 as upfront payment
Card: £9,000 over 24 months = £375/month
Interest paid: £0
Monthly commitment: lower, easier to manage
Total cost: £0. More manageable monthly.
Path A keeps all of Emma’s savings working. Path B reduces the monthly card repayment to a more comfortable £375 by using her savings upfront. Both cost £0 in interest.
As with the other scenarios, the property value uplift applies from day one. Emma’s home gains approximately £13,500 in value the moment the veranda is installed — whatever route she takes to pay for it.
Emma’s verdict: Either smart path costs £0 in interest and preserves her savings. Combined with the ~£13,500 property uplift, the veranda effectively costs Emma very little in net terms.
At a Glance: The Three Approaches Compared
| Approach | Interest Paid | Savings Impact | Property Uplift | Verdict |
|---|---|---|---|---|
| 0% Card (cleared in time) | £0 | Fully preserved | Yes — immediately | Best |
| 0% Card + Balance Transfer | ~£90–£200 (fee only) | Fully preserved | Yes — immediately | Excellent |
| Personal Loan (9.9% APR, 5yr) | ~£4,000 | Preserved | Yes — immediately | OK if 0% unavailable |
| Pay Cash from Savings | £0 | Significantly depleted | Yes — immediately | Often the worst option |
| Wait and Save | £0 | Grows in meantime | Delayed by years | Years of delayed benefit |
What About Dedicated Home Improvement Finance?
Some home improvement companies offer their own finance products — fixed-term loans at a stated APR, processed at the point of sale. These can be convenient, but convenience usually comes at a cost.
Typical rates for dedicated home improvement finance through retailers sit anywhere from 9.9% to 18% APR, and the terms are fixed. By contrast, a 0% credit card is completely flexible: pay more in good months, less in tighter months, and clear it whenever you like.
We’re in the process of developing our own credit facility at The Good Veranda Company, and we’ll update our website when it’s available. In the meantime, independent 0% cards accessed through comparison sites are the most cost-effective route for most customers.
One practical note on TGVC’s payment terms: we take 50% on order, 40% when the goods arrive at our warehouse (before installation), and 10% on completion once you’re happy with the finished work. This staggered structure actually works well with a 0% card — many customers put the deposit on the card and pay the remainder by bank transfer, using the card specifically to gain Section 75 protection on the deposit.
The Honest Bit: When This Approach Doesn’t Work
The 0% card strategy works brilliantly when you have the income and discipline to clear it within the promotional window. It doesn’t work well if:
- Your credit score means you only qualify for cards with short 0% periods or low credit limits
- Your monthly budget is tight and you need the certainty of a fixed long-term payment
- You know from experience that having available credit leads to spending it on other things
- You’re close to retirement and prefer no borrowing of any kind
In these cases, a personal loan at a competitive rate from a comparison site is a perfectly reasonable choice. Use MoneySavingExpert’s loan eligibility checker or Which?’s personal loans guide to compare current rates.

Is it better to pay cash or finance a home improvement?
If a 0% purchase credit card is available to you, it’s almost always smarter to use it and keep your savings working. You pay no interest, your savings keep earning, and you typically end up financially better off than if you’d paid cash.
How long can I get 0% on a credit card for home improvements?
Currently the best 0% purchase credit cards offer up to 25–26 months interest-free. Check MoneySavingExpert’s eligibility checker to see what you’d qualify for — it uses a soft search that won’t affect your credit score.
What do I do if I can’t repay the 0% card before the interest-free period ends?
Transfer the remaining balance to a new 0% balance transfer card before the promotional period expires. Most charge a one-off fee of around 3%. Even with this fee, the total cost is a fraction of what you’d pay in interest on a personal loan.
Does a veranda add value to my home?
Research indicates it can. Nationwide Building Society data shows a 10% increase in usable floor area can add up to 5% to a property’s value. We explore this in detail in our article on veranda property value and ROI.
Can I pay for a veranda on a 0% credit card?
Yes — we accept credit card payments. Many of our customers use 0% purchase cards to spread the cost interest-free.
What are TGVC’s payment terms?
We take 50% on order, 40% when the goods arrive at our warehouse (before installation), and 10% on completion. Many customers find the initial 50% deposit is the most natural point to use a credit card for Section 75 protection.
