Quick Answer: Remortgage to Borrow More
Yes — almost every UK lender lets you increase your mortgage at remortgage time, provided you have the equity and affordability to support the higher loan. Typical maximum LTV for capital raising in 2026 is 85% (sometimes 90%); typical income multiples are 4-4.5x household income, with up to 5.5x available for higher earners. Most uses are accepted — home improvements, buying another property, debt consolidation, family gifts, business investment — with a few exceptions (gambling debts, speculative crypto). The released cash is added to your new mortgage and repaid over the mortgage term at typical 4.5%-5.5% rates in 2026, vs 7-12% for unsecured personal loans.
Capital raising is one of the cheapest ways to borrow because the debt is secured against your home. That's also the risk — if you can't keep up payments, your home is at stake. This guide covers when it makes sense, when it doesn't, and how to maximise what you can raise.
How a Capital Raising Remortgage Works
The mechanics are simple. Your existing mortgage gets paid off in full by the new lender, and the new lender provides a bigger loan. The excess over your old balance is paid into your bank account as a lump sum, usually on the same day completion happens.
Worked example. Your home is worth £350,000. You owe £180,000 on your current mortgage. You apply for a new £270,000 mortgage (77% LTV). On completion day: the new lender wires £270,000 to your conveyancer, who pays £180,000 to your old lender to clear the existing mortgage, and transfers the remaining £90,000 to your bank account (minus any conveyancing or remortgage fees). Your new monthly payment is calculated on £270,000, not £180,000 — typically £400-£600 higher per month depending on rate and term.
The maximum you can raise depends on three things:
- Your equity — calculated from current property value minus existing mortgage balance
- The lender's LTV cap — typically 80%-90% for capital raising
- Affordability — total mortgage must fit within the lender's income multiple and stress-tested payment capacity
Whichever of these three is most restrictive becomes your binding constraint. Most borrowers find affordability is the limit, not equity.
How Much Can You Raise in 2026?
The maximum total loan depends on your property value and the lender's LTV cap. The maximum amount you can raise on top is the difference between that total and your current outstanding mortgage. Worked through at common property values:
| Property value | Existing mortgage | Max new mortgage (85% LTV) | Cash you can raise |
|---|---|---|---|
| £250,000 | £100,000 | £212,500 | £112,500 |
| £350,000 | £180,000 | £297,500 | £117,500 |
| £450,000 | £220,000 | £382,500 | £162,500 |
| £600,000 | £280,000 | £510,000 | £230,000 |
But affordability typically caps you well below the equity ceiling. Typical 2026 income multiples:
- 4.0-4.5x household income — standard for most employed applicants
- 4.5-5.0x — Halifax, Nationwide, Barclays for joint applicants with strong profiles
- 5.0-5.5x — Higher-earner products (typically requires income £75,000+ single or £100,000+ joint)
- Up to 6x — Professional lenders (Kensington, Clydesdale Professional) for medical, legal, accounting professionals
So a household earning £60,000 with a £180,000 existing mortgage on a £350,000 property may be limited to a £240,000-£270,000 total (4-4.5x income), allowing £60,000-£90,000 cash raised — even though equity supports £117,500.
What Lenders Accept as the Reason for Raising
Most reasons for capital raising are accepted by mainstream UK lenders in 2026. You'll be asked to declare the purpose on the application, and the lender may ask for evidence on completion. Accepted purposes:
Universally accepted:
- Home improvements — extensions, kitchens, bathrooms, loft conversions, garden offices. Easiest reason — lenders see it as adding value to their security.
- Debt consolidation — consolidating credit cards, personal loans, and other unsecured debt into the mortgage. Some lenders cap the proportion (commonly 25-50%).
- Second property purchase — deposit for a buy-to-let, holiday home, or second residential.
- Family gift / Bank of Mum and Dad — gifting deposit to children or other family. Widely accepted; the recipient's lender may require a gifted deposit letter.
- Major life expenses — wedding, IVF treatment, school fees, university tuition, divorce settlement.
Accepted with extra checks:
- Business capital — many lenders accept but require business plan, accountant's letter, or evidence of the receiving business.
- Tax bill payment — accepted in principle, particularly for HMRC self-assessment bills.
- Buying out an ex-partner / divorce settlement — accepted but conveyancer needs court order or formal separation agreement.
Often restricted or refused:
- Gambling-related debt
- Speculative cryptocurrency investment
- Forex / day trading capital
- Funding to lend to third parties
- Cash withdrawal without specified purpose ('general' or 'savings')
Lenders increasingly cross-check stated purposes against bank statements. If you state 'home improvements' but the funds immediately move to a gambling site or crypto exchange, your account may be flagged. Be honest on the application.
Capital Raising vs Further Advance vs Personal Loan
Three common ways to access cash secured against (or related to) your home:
| Method | Best for | Typical rate (2026) | Term |
|---|---|---|---|
| Capital raising remortgage | When your deal is ending; raising £20,000+ | 4.5-5.5% | 10-30 yrs |
| Further advance (same lender) | Mid-fix without ERC; smaller sums | 5.0-6.5% | 5-25 yrs |
| Secured loan / second charge | High ERC; complex profile | 7-12% | 3-25 yrs |
| Unsecured personal loan | Sums under £25,000; short-term | 7-12% | 1-7 yrs |
| Credit card (0% offer) | Sums under £10,000; pay off in 12-24 months | 0% intro, then 20%+ | 12-24 months |
When to choose capital raising remortgage: Your current deal is ending soon (no ERC), you need £20,000+, you want the longest term and lowest monthly payment.
When to choose a further advance: You're mid-fix with a large ERC, you need extra borrowing now, your current lender offers further advances at reasonable rates. The further advance runs alongside your existing mortgage — usually on a separate rate for a separate term — without triggering an ERC on the existing loan.
When to choose a secured loan: Mid-fix with high ERC, you don't want to disturb the current mortgage, OR your credit profile has worsened and you'd struggle to remortgage.
When to choose a personal loan: Sums under £25,000, you want to pay off quickly (3-5 years), you don't want to secure debt against your home, and you have decent credit.
How LTV Bands Affect Your Rate When Raising
Capital raising pushes your LTV higher, which often pushes you into a more expensive rate band. UK mortgage rates are tiered at 60%, 75%, 80%, 85%, and 90% LTV — each step up adds roughly 0.2%-0.5% to the rate.
Worked example. £350,000 property, £180,000 current mortgage (51% LTV).
| Cash raised | New mortgage | New LTV | Typical rate | Monthly payment* |
|---|---|---|---|---|
| £0 (rate switch only) | £180,000 | 51% | 4.4% | £985 |
| £30,000 | £210,000 | 60% | 4.4% | £1,149 |
| £75,000 | £255,000 | 73% | 4.6% | £1,420 |
| £90,000 | £270,000 | 77% | 4.8% | £1,527 |
| £117,500 (max at 85%) | £297,500 | 85% | 5.1% | £1,738 |
*Based on 25-year repayment term
Practical takeaway: Raising £30,000 (staying at 60% LTV) costs you ~£164/month extra at the same rate. But raising £117,500 (pushing to 85% LTV) costs you £753/month extra — partly because of the larger principal, partly because of the higher rate on the entire loan. If you only need a moderate sum, raising less can dramatically reduce the cost.
When Borrowing More Doesn't Make Sense
Capital raising is cheap per month but expensive over the long term, because you spread repayment over your full mortgage term. Common scenarios where remortgaging to borrow more is the wrong choice:
Small short-term need. If you need £8,000 for 18 months, a 0% credit card or 3-year personal loan will cost you less total interest than a 25-year capital raise.
Consolidating low-interest unsecured debt. If your credit card or personal loan is at 6-8%, the case for consolidating into a 25-year 4.5% mortgage is weaker than it looks. £20,000 at 6% over 4 years = £2,549 total interest; £20,000 at 4.5% over 25 years = £13,279 total interest. The mortgage is cheaper monthly but 5x more expensive overall.
You're approaching retirement. Raising £100,000 when you're 50 and planning to retire at 65 means you've got 15 years to pay it back at retirement levels of income. Many lenders won't lend past retirement age without pension income evidence.
Your property is in a falling market. If house prices in your area are dropping, raising your LTV today could leave you in negative equity if values continue falling.
You can't comfortably afford the higher payment. Aim to keep your mortgage payment under 30-35% of net household income.
Important: Your home may be repossessed if you do not keep up repayments on your mortgage. There will be a fee for mortgage advice. The actual rate available will depend on your circumstances. Think carefully before securing other debts against your home.
