New Build Reservation Fee & Reservation Agreement Explained
Before paying a new build reservation fee, understand what the reservation agreement should tell you, when money may be refundable and which costs, dates and property details to check.
A new build reservation fee is usually one of the first payments you make when you decide to secure a particular plot. It can feel like a relatively small step compared with the deposit and mortgage that follow, but the reservation agreement contains information that can shape the rest of the purchase.
Before paying, understand exactly what you are reserving, what the fee covers, how long the reservation lasts and what happens if you decide not to proceed.
For buyers using developers covered by the New Homes Quality Code, the rules changed for homes reserved from 2 March 2026, making the current reservation requirements particularly important to understand.
What is a new build reservation fee?
A reservation fee is a payment used to secure a specific new build home for an agreed reservation period.
The developer should normally stop actively offering that plot to other buyers during the reservation, subject to the terms of the agreement.
It is not the same as the larger contract deposit normally paid when contracts are exchanged.
Do not pay a reservation fee purely because you are worried another buyer will take the plot. First make sure you have enough information to decide whether the home, developer and purchase timetable are suitable.
What is a new build reservation agreement?
The reservation agreement is the document setting out the terms on which the property is being held for you.
It should identify the home and explain important parts of the transaction.
If the developer is registered with the New Homes Quality Board and your reservation falls under Code V2 from 2 March 2026, the Code sets out detailed information that must be included before the agreement is entered into.
This includes information about the price, reservation fee, warranty, tenure, expected completion, management costs and the deadline for exchange.
What should you check before paying a reservation fee?
At minimum, make sure you know:
the exact developer or seller
development name and plot number
purchase price
reservation fee
how long the reservation is valid
whether and when the fee is refundable
the expected exchange deadline
the expected completion period
tenure
warranty provider
parking arrangements
estimated management or service charges
what is included in the specification
how changes and upgrades are handled
If any of these points are unclear, ask before paying.
The sales office should not be your only source of advice. Use an independent conveyancer to explain the legal effect of the documents.
Is a new build reservation fee refundable?
It depends on the agreement and the rules that apply.
The GOV.UK home-buying guide warns that reservation fees may only be refundable in certain circumstances, so buyers should check the small print before paying.
For qualifying reservations covered by New Homes Quality Code V2, there is a 14-day cooling-off period after the Reservation Agreement is signed. The Code says a customer who ends the agreement during that cooling-off period can have the reservation fee refunded in full.
Different rules can apply after the cooling-off period or where a development is not covered by the Code.
Check your agreement rather than assuming every reservation fee is refundable.
How long do you get before exchange?
Developers often want the purchase to progress quickly after reservation.
A key 2026 change under New Homes Quality Code V2 is that, where the Code applies, the date by which contracts must be exchanged should not be less than six weeks after reservation unless the customer asks for an earlier date.
That period includes the Code's 14-day cooling-off period.
Your individual legal timetable still depends on the transaction, so tell your conveyancer and mortgage adviser about the deadline immediately.
Our new build mortgage guide explains how the mortgage process fits around reservation, valuation and completion.
What completion information should you receive?
For Code-covered homes, the reservation information includes the developer's expected completion date.
When buying off plan, this may initially be an estimate rather than a fixed moving day.
Make sure you understand:
how the completion estimate will be updated
when the developer can serve notice to complete
how much notice you will receive
what happens if the build is delayed
whether the contract contains a long-stop mechanism
If the property is not yet built, read our guide to buying a new build off plan.
Check management charges before reservation
Do not wait until the legal pack arrives to discover that the property has ongoing estate costs.
Under the current New Homes Quality Code, reservation information for covered homes includes the estimated yearly cost of management services, relevant tenure costs and how shared spaces, roads and amenities are expected to be managed.
Ask for enough information to understand what the annual figure pays for and how it may change.
Our service charges and estate management fees guide explains the questions worth asking.
Check what is included in the property
Reservation is the point to separate the actual specification from the show-home presentation.
Ask for written details covering:
kitchen specification
appliances
flooring
bathrooms
wardrobes
landscaping
fencing
parking
garages
electric vehicle charging
optional extras
If you are offered upgrades or financial contributions, make sure they are properly recorded and disclosed.
Our new build incentives guide explains why the real value of an incentive can differ from the developer's headline figure.
Research the developer before you reserve
A reservation fee should come after developer research, not before it.
Look at the housebuilder's current customer satisfaction data, third-party reviews, development record and aftercare comments.
Browse new build developers and compare the latest developer rankings.
New Build Rankings keeps HBF customer satisfaction data separate from consumer review scores so you can see what each source actually measures. Read how we rank developers for the methodology.
What if the developer changes something after reservation?
Small changes can happen during construction, especially when you reserve off plan.
Where the New Homes Quality Code applies, major changes that significantly affect the size, appearance or value of the home have specific protections. The Code says customers must be told in writing and can have cancellation rights if they find the major change unacceptable and act within the specified period.
Ask your legal adviser what your contract says about changes.
If a particular feature matters enough that you would not buy the home without it, make sure it is documented rather than relying on a sales conversation.
Can the developer pressure you to reserve?
You should have enough time and information to make an informed decision.
The New Homes Quality Code includes a principle that registered developers should not use high-pressure selling techniques to influence a customer's decision.
Limited plot availability can be real, but that does not remove the need to understand the property, costs and paperwork.
If you feel you need more information, ask for it.
New build reservation checklist
Before paying the reservation fee:
Research the developer.
Check the exact plot and development plan.
Read the reservation agreement.
Understand the cancellation and refund terms.
Confirm the exchange deadline.
Ask for the estimated completion period.
Check tenure and management costs.
Confirm the warranty provider.
Get the written specification.
Record all incentives and upgrades.
Speak to your mortgage adviser.
Instruct an independent conveyancer promptly.
Keep copies of the agreement and sales information.
Do not rely on an important verbal promise.
The bottom line
A new build reservation fee may be small compared with the overall purchase price, but paying it marks the start of a serious transaction.
Use the reservation period to verify the property, developer, mortgage, legal terms and ongoing costs.
For buyers covered by the New Homes Quality Code, the current 2026 rules provide clearer reservation information and a cooling-off framework. Even so, the safest approach is the same: read before you sign, ask before you assume and get independent legal advice on anything you do not understand.
