Mortgage fees explained (UK): arrangement fee, booking fee, valuation fee and broker fee

Summary

Mortgage fees are the extra costs you may pay to arrange and complete a mortgage. They can be:

  • upfront (paid during application), or
  • added to the mortgage (so you pay interest on the fee).

This guide explains the most common fees in plain English and shows how to compare two deals so you don’t get caught by a “low rate” that costs more overall.

Key terms (quick definitions)

  • Arrangement fee (also called product fee): a fee for setting up the deal. /glossary/arrangement-fee/
  • Booking/reservation fee: paid to secure a rate (often non‑refundable).
  • Valuation fee: the lender’s valuation of the property (not the same as a survey).
  • Broker fee: a fee charged by some mortgage brokers (varies).
  • APRC: an “overall cost” rate shown on mortgage documents. /glossary/aprc/

How it works

The main fee types (and what they usually mean)

Arrangement fee (product fee)
Often charged by the lender for a particular mortgage product. Some lenders offer a choice of:

  • lower rate + higher fee, or
  • higher rate + lower (or no) fee.

Booking/reservation fee
Often paid early in the process to “reserve” a product. Refund rules vary, so treat it as potentially non‑refundable unless the lender clearly says otherwise.

Valuation fee
The lender’s valuation is for the lender’s benefit: it checks the home is worth the amount being borrowed and is acceptable security. Some lenders include it for free on some products.

Broker fee
Some brokers charge a fee; others do not. Fee structure varies (fixed fee vs percentage) and may depend on case complexity.

Why fees matter (especially for shorter fixes)

If you’re comparing a two‑year fix, you only have two years of rate savings to “earn back” a fee. Over five years, the same fee may look smaller relative to the interest you pay.

Also remember:

  • If you add a fee to the mortgage, you pay interest on it.
  • If you pay it upfront, you need extra cash on top of your deposit and other buying costs.

Worked examples

These examples are illustrative and simplified.

Example 1: Fee vs rate over two years

Mortgage: £200,000 (interest‑only example to keep the maths simple)

  • Deal A: 4.20% + £999 fee
  • Deal B: 4.40% + £0 fee

Approx monthly interest:

  • A: (£200,000 × 0.042 / 12 ≈ £700)
  • B: (£200,000 × 0.044 / 12 ≈ £733)

Difference ≈ £33/month → about £792 over two years.

In this simplified example, the fee is larger than the rate saving. The conclusion can flip with a bigger mortgage or a bigger rate gap.

Example 2: Adding the fee to the mortgage

If the £999 fee is added to the mortgage balance, you borrow £999 more and pay interest on it. Over time that can make the “real” cost of the fee higher than the sticker price.

If you add fees, compare the total cost, not just the headline rate.

Example 3: Valuation vs survey costs

The lender valuation is not the same as a buyer’s survey. You may decide to pay separately for a survey for your own peace of mind. Budget for both unless you’re sure your lender product includes a valuation and you’re not taking a separate survey.

Common mistakes

  • Comparing rates only: always compare fees and total cost over the fixed period.
  • Forgetting about cash needed upfront: fees + legal + surveys can be separate from your deposit.
  • Assuming fees are refundable: refund rules vary; check the product details.
  • Ignoring the “add to loan” effect: adding fees increases borrowing and interest.
  • Mixing up valuation and survey: a valuation protects the lender, not you.
  • Not checking broker fees early: ask upfront to avoid surprises.
