Am I overpaying on my mortgage?
You are likely overpaying if your rate is higher than the best available for your loan to value band, property type and ownership. Most people find out months after a better deal appeared, because nobody checks for them. Savings Intelligence checks every property you own, every day, so you know where you stand.
How Savings Intelligence works
To answer am I overpaying on my mortgage, Theo reads your balance, rate, remaining term, fix end date, property type, ownership and band. Every night it matches your profile against 10,000+ live deals from 100+ UK lenders and works out the monthly payment at today’s best rate for your band. It shows the plain monthly difference, then lists the lender fee and any early repayment charge separately, with how many months the saving takes to cover them. If the costs outlast the deal paying for them, Theo says so plainly.
The early repayment charge, counted properly
An early repayment charge is what your lender charges for leaving a fixed deal early, and it can wipe out years of savings. Theo includes it only when you would actually pay it. If your fix ends within about six months, you can usually apply now and complete the day it ends, so Theo marks the charge as not payable. See early repayment charges explained.
Compare the whole market for your band
If the answer to am I overpaying on my mortgage is yes, the next question is who with. With Premium, you can step through every live deal for your band, sorted by lowest rate, lowest fee or lowest total cost over the deal, with the lender, rate, monthly payment and fee for each. Sorting by total cost often reorders the list: a headline low rate with a big fee can drop well down. Premium also shows the lender behind today’s best rate, how much it would take to reach your next loan to value band, and, with two or more properties, the detail of any equity move.
Deal Watch, for a home you are buying
