Platform mortgages review What is Platform?

Platform is the mortgage arm of the Co-operative Bank. It came into being in February 2003, when Britannia Building Society subsidiaries Platform Home Loans and Verso merged, before becoming part of the Co-operative Bank in 2009. Platform is a member of UK Finance which is an associate member of the Association of Mortgage Intermediaries. The Co-operative Bank is authorised by the Prudential Regulation Authority and regulated by the Financial Conduct Authority and the Prudential Regulation Authority - No. 121885.

It aims to set itself apart from its competitors by taking an ethical approach to mortgage lending, working with organisations such as homelessness charity Centrepoint in order to give something back to society. 

Its mortgages are only available through an intermediary meaning customers can't deal directly with the company. If you don’t have a broker, we suggest Habito*, which gives independent whole-of-market advice at no cost to the end consumer.

What types of mortgages does Platform offer?

Platform predominantly offers fixed-rate deals for first-time buyers, movers and those who wish to remortgage. It has a comprehensive residential and buy-to-let mortgage range, which sometimes comes with incentives such as cashback. It is known for being competitive in the interest rates it charges and it often appears on best-buy lists, including our mortgage best-buy tables, provided by Habito*.  

Platform has recently added a professional mortgage to its range, which is available to people in certain professions that tend to have clear salary progression, including accountants, actuaries, architects, barristers, chartered surveyors, dentists, medical doctors, optometrists, pharmacists, solicitors and vets. These mortgages offer income multiples of up to 5.5 times annual salary, with a minimum income requirement of £35,000.

How much can I borrow with Platform?

The amount that you will be offered for a Platform mortgage will be determined by its affordability assessment, which takes into consideration your existing financial commitments and how much you can reasonably afford if interest rates were to rise substantially over the lifetime of the loan. Part of the calculation is based on the applicants' income, with multiples at the following levels:

  • 4.75 times annual income for loans up to 60% LTV
  • 4.49 times annual income for loans over 60% LTV
  • 4.49 times annual income for Help to Buy loans
  • Up to 5.5 times annual income for professional mortgages

What interest rates does Platform charge?

Interest rates across all mortgage lenders change frequently, so it is a good idea to check with your mortgage broker at the time you are planning to make your application for the most up-to-date deals. At the time of writing, Platform is offering residential mortgage rates for:

  • 2-year fixed rate mortgage deals starting at 5.09%
  • 3-year fixed rates mortgage deals starting at 5.04%
  • 5-year fixed rates mortgage deals starting at 4.84%

Rates vary depending on the loan-to-value, mortgage size and the product fee that you pay and will change regularly. To find the most up-to-date mortgage rates use our Mortgage Rate Comparison Tool which allows you to check current mortgage deals.

What fees does Platform charge?

In addition to the fees you pay to a solicitor for the conveyancing part of a property purchase, there are also charges levelled by the mortgage lender. In the case of Platform this can include a product fee for some of its mortgages, which can be as high as £1,999. This fee can be added to the mortgage total, although interest will then also be payable on it, at the same rate as the mortgage itself.

In terms of valuation fees, Platform offers one free standard valuation per application for residential and buy-to-let remortgages. There is the option to pay more to have a homebuyer's report or an additional building survey completed at the same time as the valuation, with the fees for this on a sliding scale depending on the asking price for the property. 

Can you make overpayments on your Platform mortgage?

It is possible to overpay your mortgage by up to 10% of the outstanding mortgage balance each year without incurring a financial penalty. Any payment over 10% will be subject to an early repayment charge. In addition, any cashback provided as part of the mortgage deal has to be repaid if the mortgage is redeemed during the initial offer period.

The exact terms of early repayment charges are detailed in the terms and conditions of the individual mortgage product and should be explained to you by your mortgage adviser when you take it out.

What is the maximum mortgage term with Platform?

The maximum mortgage term is 40 years, although the exact length will be determined by the applicant's age when they take out the mortgage. Platform mortgages must end by the time the borrower reaches age 75. It is possible for borrowers to take on a term that goes beyond retirement age if they can show that their pension income is likely to be sufficient to service the mortgage loan.

What credit reference agency does Platform use?

Platform primarily uses Experian for its searches, so it is a good idea to check both your overall credit score and the information in your credit report to make sure it's accurate before making your application. When you apply for a mortgage with Platform, it runs a credit check on you, looking at your past financial behaviour and overall creditworthiness. This helps determine whether it will approve your loan and, if so, how much you will be allowed to borrow and at what interest rate.

There are three main credit reference agencies in the UK: Experian, Equifax and TransUnion.

Does Platform offer mortgages to people with bad credit?

Platform sits between mainstream prime lenders and specialist lenders with products specifically designed for people with impaired credit. While it will consider applications from those with mild adverse credit, including one missed mortgage payment or two unsecured loan payments within the previous 12 months, the applicant is required to provide an explanation to the underwriter and to also pass the broader credit score assessment.

Generally, Platform will not approve mortgages where the applicant:

  • Is bankrupt or has been discharged from bankruptcy in the previous 6 years
  • Has an IVA or had one in the last 6 years
  • Has an unsatisfied CCJ
  • Has had a CCJ in the past 6 years for more than £100
  • Has defaults registered in the past 12 months or defaults during the past 6 years totalling more than £500
  • Has had a repossession

Platform customer reviews

According to customer review site Trustpilot, Platform's parent company The Co-operative Bank scores 1.3 out of 5.0, based on around 3,000 reviews. The majority of respondents had negative views, with 80% claiming it was a "bad" company, mostly based on poor customer service. However, as these reviews don't specifically cover Platform, they aren't necessarily representative of the experiences of customers with the mortgage arm of the business. According to a review by Which? though, Platform is ranked 8th out of 15 lenders, based on a range of factors, including customer service and value for money.


Platform could be a good option for you if you are looking for a lender with ethical credentials, as well as if you have minor blips on your credit record. It may also be appealing to those in professions that mean they will qualify for a professional mortgage, which offers higher income multiples to supercharge your borrowing power. As you have to go through a mortgage broker, there should be the opportunity to weigh up how it compares to other lenders at the time you are looking for a mortgage, including whether you may be able to benefit from cashback or other incentives.
