Lloyds Bank is the cheapest lender for the third month in a row, but this time it shares the crown with another provider, Nationwide Building Society, according to the latest Which? analysis.
April has been a mixed month for borrowers, with rate hikes dominating the beginning of the month and cuts in the second half. The best rates are now lower than those seen at the start of April, but more expensive than February's best deals.
Our research uses Moneyfacts mortgage data collected throughout March to compare the best deals across 24 different mortgage scenarios. A score of 100% represents a market-leading mortgage deal based on our typical borrower scenarios.
Nationwide and Lloyds received an overall score of 97%, indicating they offered excellent mortgage deals for a range of borrowers. However, other lenders may be more cost-effective depending on your situation.
Read on to find out which other lenders consistently offered competitive deals and see the top five cheapest providers for first-time buyers, home movers and remortgagers.
April's cheapest mortgage lenders
Nationwide Building Society and Lloyds Bank were the cheapest lenders overall in April. Two lenders topping the table show how highly competitive the mortgage market is currently.
Nationwide is also the only Which? Recommended Provider (WRP) for mortgages in 2026.
For the typical borrower, the providers were £150 a year cheaper than the next best lender, Santander, which achieved an overall score of 96%.
Our analysis reveals that some lenders have slipped down the rankings following rate rises. For example, in February HSBC had the joint-second-highest overall score of 97%. However, in April and March it scored 91%. This means that in April, for a typical borrower, it was £900 more expensive per year than the cheapest lenders.

Recommended Provider, a lender must get a top customer score, consistently offer competitive deals and be fully covered by the Financial Conduct Authority banking standards regime.
Cheapest lenders for first-time buyers
Our research enables us to look more closely at the cheapest lenders for different types of borrowers, including first-time buyers.
Lloyds Bank was also the cheapest for first-time buyers.
For a typical first-time buyer, Lloyds was almost £300 cheaper per year than the next-best lenders.
First-time buyers are the riskiest borrowers for lenders, as they typically have smaller deposits and usually need to take out larger loans. So you sometimes see a variety of smaller lenders in the table. In April, for example, Leeds Building Society was among the cheapest lender for this group of borrowers.

About our research
In our analysis, we use Moneyfacts mortgage data collected weekly on each Monday of the month.
To determine the cheapest lender of the month, we combine results across all three borrower types: first-time buyers, home movers and remortgagers. A lender can only be named overall cheapest if it offers at least one of the most popular mortgage products across all three borrowers.
We've used market data to identify the most popular mortgage types and include them in our research. Lenders are not penalised for not offering a particular type of mortgage.
To score providers, we create a typical borrowing scenario using market data, including loan amounts and term lengths. We factor in the interest rate and any initial fees to calculate the monthly cost. Each lender’s best deal is then compared with the cheapest product available for that scenario.
