If you’re planning to buy your first home, move house, or remortgage, you’ve likely come across the phrase “whole of market” mortgage advice. But have you ever considered what it really means – and why could it be important for you? 

In this article, I explain what whole of market advice is. I outline how it differs from going directly to a bank, using a tied broker, or relying on comparison sites. And I explore why it could help you find a mortgage that genuinely fits your goals.

What Does ‘Whole of Market’ Mean? 

A whole of market mortgage adviser has access to a comprehensive range of mortgage products from across the entire marketplace.  That includes high street banks, specialist lenders, building societies, and exclusive adviser-only deals. 

Unliketied advisers (such as those based at banks, who can only offer that bank’s products) or multi-tied advisers (for example, brokers working for large estate agencies like Connells, who only use a limited panel), whole of market advisers aren’t restricted. They can assess a wide range of options that suit your individual circumstances. 

The Financial Conduct Authority (FCA) defines “whole of market” advice as advice given after reviewing a sufficiently wide range of mortgage products. Brokers must understand those products and ensure their recommendations are the most suitable based on that review. In practice, this means regularly assessing a broad selection of mortgages and guiding clients towards the most appropriate outcome.

It’s worth noting that even a whole of market adviser won’t have access to every mortgage product. Some lenders – such as First Direct or Lloyds – choose not to offer mortgages via intermediaries. However, this doesn’t diminish the value of whole of market advice. These lenders often operate on a direct-to-consumer model that may not always be the most competitive or suitable for everyone. A whole of market adviser is still best placed to assess the widest available range of products and criteria. 

Why Whole of Market Advice Matters 

When you’re making a major financial decision, choice and impartiality matter. Let’s say you’re a first-time buyer with a strong income but a small deposit. A bank’s tied adviser will only offer you their own product – even if there are more suitable deals elsewhere.  This could mean borrowing less than you hoped, or needing to put down a higher deposit. 

However, a whole of market adviser will search a wide range of lenders. This includes those who specialise in low-deposit mortgages or offer enhanced income multiples. 

Real Customer Example:

Jess, a 32-year-old solicitor, was looking to buy her first home in Cardiff. She had a strong salary of £50,000, but assumed she was limited to standard income multiples – usually around 4.5 times her salary (£225,000). As a result, she didn’t think she could afford the type of property she wanted. 

Having researched the whole mortgage market, I recommended a lender offering a “professional mortgage” specifically for her line of work. It allowed her to borrow up to six times her income (£300,000). This made it possible for her to buy a home in her preferred area without compromising her goals. 

Who Can Benefit from Whole of Market Advice? 

• First-Time Buyers: Gain access to products with enhanced income multiples and low or no deposit requirements. 

• Home Movers: Explore a wider range of lenders who can accommodate higher borrowing, complex income, or unique employment structures. 

• Remortgagers: Avoid your current lender’s Standard Variable Rate and explore new deals from the whole market – not just your existing bank. You can also consider options like equity release for debt consolidation or home improvements. 

• Buy-to-Let Investors: Whole of market advice can help you access lenders who support a range of strategies – from HMOs and limited company structures to holiday lets. 

Whole of Market Advice vs. Comparison Sites 

Comparison sites are a popular tool for checking mortgage rates, but there are some important differences between using one and working with a whole of market adviser: 

• Breadth of Access: Comparison sites typically show a limited slice of the market and may exclude specialist lenders or deals only available through brokers. 

• No Regulated Advice: These sites offer data, not advice. They won’t assess your individual needs or recommend what’s most appropriate for you. 

• Surface-Level Matching: What looks like the “cheapest deal” may not be suitable – or even achievable – once your full financial profile is taken into account. 

Whole of market advisers go beyond listings. We assess your full situation and use our access to the wider intermediary market to make tailored recommendations. That personalised support can make a significant difference in both securing a mortgage and getting terms that truly suit you.
