How Excelergy Mortgages works

Every deal is taken from information the lender publishes itself: its own rates pages, the rate sheets it posts online, or the product guides it publishes for mortgage brokers. Each deal has a source link so you can check the original.

We do not buy data from a rates aggregator and we do not accept payment from lenders to be listed.

We re-check every lender once a week, on Monday mornings. The footer of the comparison page shows the date the rates were last checked.

Lenders can change or withdraw a deal at any time, sometimes with less than a day's notice, so a deal may have changed since we last looked. Always confirm on the lender's own website before you rely on a figure.

Barclays, Coventry Building Society, HSBC UK, Leeds Building Society, Lloyds Bank, NatWest, Nationwide, Santander UK, Skipton Building Society, TSB, Virgin Money and Yorkshire Building Society.

Halifax is not listed separately because it now directs new mortgage customers to Lloyds and does not publish its own rates.

No. The UK market has thousands of mortgage products, and many smaller lenders only sell through brokers and never publish their rates. We show a representative set of deals from large lenders that advertise publicly, covering 2 and 5 year fixes and trackers across the main loan to value bands.

A mortgage broker can search a much wider range, including deals that are never advertised.

Several lenders, including Nationwide, Virgin Money, TSB, Skipton and Coventry, publish their full range in a guide written for mortgage brokers. Those deals are real and current, but some are only available through a broker rather than by going to the lender directly. The lender or a broker can confirm.

It is the standard repayment mortgage formula: the payment that clears the loan, with interest, over your chosen term if the rate stayed the same throughout. It does not include the product fee, insurance, or any other costs.

The figure applies to the initial deal period only. When the deal ends the rate changes, so your payment will too.

It is every monthly payment you would make during the deal period, plus the product fee. For a 2 year fix that is 24 payments plus the fee; for a 5 year fix it is 60 payments plus the fee. Trackers are compared over 2 years.

It lets you compare a low rate with a big fee against a slightly higher rate with no fee on equal terms. Only compare it between deals of the same length: a 5 year total will always be bigger than a 2 year total.

Each deal has a maximum loan to value (LTV). If your loan is a bigger share of the property value than the deal allows, you would not qualify, so we hide it. Increase the deposit, or reduce the amount to borrow, and more deals appear.

In the Max LTV filter, bands you cannot reach are greyed out. Hover over one to see the deposit it needs.

They change what you type in that box. In Deposit mode you enter your deposit (or, if remortgaging, your equity) and we work out the loan. In Borrow mode you enter the amount you want to borrow and we work out the deposit. Switching converts the figure, so your loan stays the same.

It adds up your income (counting half of any bonus, overtime or commission), takes off a year of your monthly debt and childcare costs, and multiplies the result by 4, 4.5 and 5, the range most UK lenders use. It also checks your deposit, because most lenders will not lend more than 95% of the property value.

Real lenders use their own detailed models, so treat the result as a guide. The See deals at this price button opens the comparison with that property price and your deposit filled in.

The rates in force for 2026/27: Stamp Duty Land Tax in England and Northern Ireland, Land and Buildings Transaction Tax in Scotland, and Land Transaction Tax in Wales. It covers first-time buyer relief, the surcharges for additional properties and, in England and Northern Ireland, the surcharge for non-UK residents.

It does not cover every relief or special case, so your conveyancer will confirm the exact figure.

It compares doing nothing, switching when your deal ends, and switching now, all over the same period: the months left on your current deal plus the length of a new deal. For each it adds up the interest you would pay plus any fees and early repayment charge. Capital repayments are left out because you repay the same debt whichever you choose.

It uses the remortgage deal with the lowest cost over the deal for your loan to value. Your own lender may also offer existing customers a "product transfer" deal, which is often worth comparing.

Overpaying saves interest at your mortgage rate, with no tax to pay on that saving. Savings earn interest that may be taxed. So if your mortgage rate is higher than what your savings would earn after tax, overpaying usually comes out ahead on the numbers.

But money paid into your mortgage is hard to get back, so most people keep an emergency fund first. Check your deal's overpayment allowance (often 10% a year) to avoid early repayment charges. The overpayment calculator shows the interest and time you could save.

It works out your "net wealth" each year down both paths. If you buy, that is what you would walk away with if you sold: the home's value, minus the mortgage left and selling costs. If you rent, it is the deposit, stamp duty and fees you did not spend, invested at your savings rate. Each month, whichever option is cheaper invests the difference.

The answer depends heavily on house prices, rent rises and investment returns, none of which anyone can predict, so try a few different figures. Buying usually loses in the first few years because of the costs of buying and selling.

Average prices come from HM Land Registry's UK House Price Index, by local authority and property type (detached, semi-detached, terraced, flat). Northern Ireland figures are not split by type. Average rents come from the ONS Price Index of Private Rents, by local authority and number of bedrooms; in Scotland they are published for wider rental market areas, and Northern Ireland only has a national figure. Both are updated monthly and run about two months behind.

Official figures do not give house prices by number of bedrooms, so property type is used instead. An average covers a wide range of homes, so treat it as a starting point.

If you own the property yourself, you pay income tax on the rent minus running costs, but mortgage interest is not deducted. Instead you get a tax credit at the basic rate on the interest (the "Section 24" rules). From April 2027 property income is taxed at 22%, 42% or 47%, two points above other income, and the credit rises to 22%.

A limited company deducts mortgage interest in full and pays corporation tax (19% on profits up to £50,000), but taking money out of the company is taxed again, which the calculator does not include. The lender test checks the rent covers the interest at a test rate by 125% (basic-rate taxpayers and companies) or 145% (higher and additional-rate taxpayers). Lenders vary, so treat it as a guide.

Yes. Click any column heading to sort by it, and click again to reverse the order. The arrow shows the current sort.

It copies that deal into the payment calculator further down the page, where you can add overpayments or try interest only. For fixed deals it also shows roughly what you would owe when the deal ends, and what the payment would be if you then moved to the lender's standard variable rate.

Your loan as a percentage of the property's value. Borrowing £240,000 on a £300,000 home is 80% LTV. Lenders price their deals in LTV bands (60%, 75%, 85%, 90%, 95% and so on), and lower bands usually have lower rates.

A fixed rate stays the same for the deal period, so your payment is predictable. A tracker moves with the Bank of England base rate, usually at a set margin above it, so your payment can go up or down.

You move to the lender's standard variable rate, or a similar reversion rate, unless you arrange a new deal. That is the "Then" column. It is usually much higher than the deal rate, which is why most people remortgage or switch to a new deal with their lender before the old one ends.

A fee the lender charges for the deal, sometimes called an arrangement or booking fee. Many lenders let you add it to the loan instead of paying upfront, but then you pay interest on it. Other costs, such as valuation, legal or broker fees, are not included in our figures.

The Annual Percentage Rate of Charge is a standard figure lenders must show. It combines the deal rate, the reversion rate and the main fees over the whole mortgage term. It is useful for comparing like for like, but it assumes you never switch deals, which few people do.

Most fixed and some tracker deals charge a fee if you pay off the mortgage, or overpay by more than an allowance (often 10% a year), during the deal period. Check the lender's terms before choosing a long fix if you might move or repay early.

No. Excelergy Mortgages lists publicly advertised deals and does the arithmetic. It does not know your circumstances and does not recommend any product. Whether you qualify, and which deal suits you, depends on things like your income, credit history and the property. A qualified mortgage adviser can give advice.

Your home may be repossessed if you do not keep up repayments on your mortgage.

No. We never ask for personal details and never run a credit check. Lenders only search your credit file when you apply.

Nothing on our servers. Your filter choices and the light or dark theme are remembered in your own browser so the page looks the same next time. The numbers you type are not saved or sent anywhere.

No. There are no paid placements and no commission. Deals are ordered by the column you choose, nothing else.

Use the envelope button at the top of the page, or email hello@excelergy.co.uk. Please include the lender and deal.
