Part Exchange Homes: The 2025 Guide for UK Buyers
Selling a home while trying to secure your next one can feel like a juggling act — unpredictable, stressful, and often slowed by long chains.
For many buyers across the UK, especially those eyeing new-build or luxury developments, Part Exchange (PX) has become one of the simplest and most reliable solutions.
This guide breaks down everything you need to know about part exchange in 2025: how it works, when it’s smart, and what to watch out for.
1. What Is Part Exchange?
Part exchange is when a housebuilder buys your current home directly so you can purchase one of their new properties.
Instead of waiting for a buyer, negotiating endlessly, or risking your sale falling through, the developer becomes your guaranteed purchaser.
Part exchange typically offers:
No chain
No estate agent fees
No uncertainty or fall-through risk
A faster, smoother move
In the UK, around 38% of new-home movers consider PX as part of their buying journey.

2. How Part Exchange Works
Although every developer has its own structure, PX usually follows this four-step flow:
Step 1: Valuations
The developer arranges two to three independent valuations of your existing home.
Step 2: Offer
You receive an offer based on local market evidence.
Step 3: Reservation
If you accept, you reserve the new-build home you’re buying.
Step 4: Completion
The developer buys your home; you complete your move with no chain delays.
The PX process is often 2–3 times faster than selling on the open market.

3. The Benefits of Part Exchange
1. A Guaranteed Buyer
No viewings. No negotiations. No fall-through risk.
This is especially valuable in a cooling or uncertain market.
2. No Chain Complications
Around 1 in 3 property chains collapse in the UK.

PX removes that anxiety completely.
3. No Estate Agent Fees
A typical home sale incurs 1–1.5% in agent fees — PX wipes this cost out.
4. Faster Move-In
If the new home is already built, buyers can sometimes move within weeks.
5. No Need to Refurbish Your Old Home
Developers buy your property “as is,” meaning no staging or repairs required.
6. Perfect for Upsizing or Modernising
PX is especially appealing to buyers moving from older homes into:
energy-efficient new builds
larger layouts
low-maintenance luxury developments
4. Things to Be Aware Of
Part exchange is convenient — but not perfect for everyone.
1. The Offer May Be Below Market Value
Developers typically offer 90–95% of the open-market price.

You’re paying for speed and certainty.
2. Your Home Must Qualify
Developers usually accept homes that are:
sellable
mortgageable
in good structural condition
within certain price bands relative to the new home
3. Developer Choice Is Limited
You can only PX into that developer’s own properties, so you need to love their product.
4. Not Ideal for Those Wanting Top Market Value
If maximising your selling price is your priority, selling independently might yield a higher figure — though more slowly.
5. Who Should Consider Part Exchange?
PX can be a smart move if you are:
upgrading to a new-build
seeking a chain-free move
working to a tight timeline
tired of the unpredictability of the open market
relocating or downsizing
buying a luxury or premium development and want simplicity
It’s especially useful for families, upsizers, and anyone whose home isn’t selling quickly.
6. When Is Part Exchange Not Ideal?
You may want to avoid PX if:
your home is likely to achieve well above its valuation
you want to test the open market
you need the absolute maximum sale price
you’re buying from a developer who doesn’t offer PX on your chosen plot
7. How to Get the Most Out of a Part Exchange Deal
✓ Compare recent sales on your street
Know your true market value before accepting a PX offer.
✓ Review the developer’s timeline
Some require fast exchange — make sure it suits you.
✓ Ask about incentives
Many developers offer extras such as:
stamp duty contribution
upgrades
flooring packages
legal fee contributions
✓ Check the long-stop date (if buying off-plan)
Important for new-builds still under construction.
✓ Always use an independent solicitor
Never rely solely on the developer’s recommended advisers.
Final Verdict: Is Part Exchange Worth It?
For many UK buyers — especially those targeting new-build or luxury developments — part exchange is a lifesaver.
It removes stress, cuts down the timeline and guarantees your sale, allowing you to move forward without chaos or uncertainty.
PX may not give you the absolute highest price for your existing home, but it gives you something far more valuable: certainty, speed and simplicity.
