How to Sell an Apartment Block in the UK: The Complete Guide

Posted by Block Land on 25 July 2025

If you’re wondering how to sell an apartment block in the UK or where to sell an apartment block in the UK, you’re not alone. Selling a multi-unit freehold block is very different from selling a single residential property, and choosing the wrong route can cost you tens of thousands of pounds in lost value.
 
In this guide, we’ll explore the three main options for selling an apartment block:
 
  1. Auction
  2. High Street Estate Agents
  3. Specialist Apartment Block Agents like BlockLand

Selling at Auction: Fast but Often Below Market Value

 

The benefits of selling at auction:

  • Speed – Auction sales can be quick, often completing in 28 days.
  • Certainty – Once the hammer falls, the buyer is legally committed.

The downsides:

  • Lower Prices – Properties at auction often sell at 10 to 20 percent below market value due to buyers looking for bargains.
  • Fees Impact the Price – Buyers pay hefty auction fees, meaning they often reduce their bids to compensate.
  • Limited Buyer Pool – Most auction buyers are cash investors looking for distressed or undervalued deals, which means fewer competitive bids.
  • Data Point – According to Allsop Auction Reports, average auction sales often achieve 10 to 15 percent less than private treaty sales, especially for investment properties.

Selling Through High Street Estate Agents: A Poor Fit for Blocks

 

Why high street agents struggle with apartment blocks:

  • Wrong Audience – Around 80 percent of their database consists of homebuyers, with another 15 percent being HMO or single-house investors. Very few are interested in apartment blocks.
  • Incorrect Marketing – We’ve seen 10-unit blocks listed as “10-bedroom houses,” which confuses serious buyers.
  • Over or Under-Valuation – Mispricing leads to properties sitting unsold for months, forcing sellers to accept big discounts later.
While high street agents may have large networks, they rarely have the specialist investor audience required to achieve true market value for blocks.

Which is the Best Way to Sell an Apartment Block?

If you want the fastest sale, auctions can work, but you’ll likely leave money on the table.

If you want maximum exposure, high street agents might seem appealing, but their buyer pool is not suited for apartment blocks.
