Introduction - Why buying a new build is different
Buying a new build isn’t just about choosing a home; it’s about investing in a lifestyle. You're choosing something brand new, untouched, and built for modern living. Unlike older properties that often come with quirks, repairs, and a to-do list, a new build home offers a clean slate, greater energy efficiency, and the reassurance of warranties.
Whether you're buying a new-build off-plan or purchasing a completed show home, the process is quite different from buying a pre-owned property. There are specific steps to follow, from reserving your plot and securing a mortgage to understanding what’s included and checking for any issues before you move in.
This guide explains every part of that journey in a straightforward, practical way. You’ll get a clear view of what to expect, what to watch out for, and how to make the most of your purchase.
Why new builds are worth considering
- Designed for modern energy standards, helping to reduce utility bills
- Covered by structural warranties and manufacturer guarantees
- Options to customise finishes and layout depending on the build stage
- Government and developer incentives may be available for eligible buyers.
- No onward chain, making transactions simpler and faster

Step 1 - Researching and choosing the right new build home
Buying a new build home is exciting, but it's not something to rush. With so many developers, locations, and layouts to choose from, it's worth taking the time to dig into the details before you commit. The good news? A bit of smart research now can save you time, stress, and money later.
Check the developer’s reputation
Before anything else, research the developer behind the home. Are they registered with the NHBC or another reputable warranty provider? This is often a strong indicator that they adhere to recognised industry standards.
It’s also worth searching online for reviews or asking the sales team to point you to previous developments you can drive past or visit. If you can, chat with current homeowners on the development to hear about their experience directly.
Visit the development and show homes
Show homes offer a firsthand experience of the space, layout, and build quality. However, keep in mind they’re often furnished with upgrades and extras that aren’t included as standard. Be sure to ask the sales representative to clearly explain what’s included in the base price and which features come at an additional cost.
Take a good look around the development. Think about how close the property is to roads, car parking, bin stores, and green spaces. These things can make a big difference to daily life once you’ve moved in.
Think carefully about location
Even the best-built home can lose its appeal if the location doesn’t suit your lifestyle. Explore local transport links, schools, shops, parks, and other amenities important to you. If the area is still under development, ask about plans and how they might impact your property’s value or convenience.
Visiting the neighbourhood at different times of the day can also give you a clearer, more authentic feel for the area.
Reserve your new home
Once you’ve found the right plot, you’ll be asked to pay a reservation fee. This takes the home off the market while you sort your mortgage and appoint a solicitor. Make sure you get a reservation agreement that sets out the price, what’s included, and the expected timeline.
Also, ask the developer to confirm in writing any extras they’ve agreed to include. This might be flooring, upgraded appliances, or fitted wardrobes. These details matter, and it’s best to get everything down on paper early.

Step 2 - Negotiation, incentives and deposits
Once you’ve reserved your new-build home, it’s time to iron out the final details. Unlike buying an older property, where price is often the main focus, purchasing a new build offers opportunities to secure upgrades, benefit from incentives, and clarify how your payments are structured. This is your chance to maximise the value of your purchase before contracts are exchanged.
Negotiate your deal before you reserve
Developers are often open to negotiation, especially if the development is nearing completion or you're an early buyer. While the overall price may stay the same, many developers will include extras such as upgraded kitchen appliances, premium flooring, or contributions to your legal fees.
Always ask for these incentives to be confirmed in writing before you pay the reservation fee. Once you’ve reserved the property, it becomes more difficult to renegotiate.
Look into developer and government incentives
Developers may offer a variety of incentives depending on how many homes are left to sell or the stage of construction. These can include:
- Deposit contributions
- Stamp duty paid
- Cashback on legal completion
- Free upgrades or specification packages
- Assistance with legal or moving costs
You might also qualify for government-backed schemes such as Own New, Deposit Unlock, or the First Homes Scheme. These options are designed to make buying a new build home more affordable, particularly for first-time buyers or key workers. Ask the sales advisor which schemes are available for your plot and what the eligibility criteria are.
Understand reservation fees and how deposits work
A reservation fee is required to take the property off the market. This usually ranges from £500 to £2,000 and gives you a set period to organise your mortgage and instruct a solicitor. The fee is normally deducted from the final purchase price.
For off-plan purchases, your deposit may be paid in stages. Some developers ask for a portion in exchange, and the rest closer to completion. Make sure you understand the full payment breakdown before moving forward.
Confirm all extras in writing
If you’ve agreed on specific upgrades or incentives such as integrated appliances, flooring, or fitted wardrobes, ensure these are listed in your reservation agreement. Verbal assurances can easily be forgotten or misinterpreted. Everything should be documented from the start.
Prepare for the exchange of contracts
Once the reservation is complete, the legal process begins. You’ll need to appoint a conveyancer, confirm your mortgage offer, and be ready to exchange contracts, usually within a few weeks. Having everything prepared in advance helps avoid unnecessary delays and keeps the purchase on track.

Step 3 - Securing your mortgage and legal representation
Buying a new build comes with a few extra considerations when it comes to financing and legal work. Lenders often place time limits on mortgage offers for new builds, and not all conveyancers are experienced in handling the specific legal checks involved. Getting the right advice early can make the process smoother and help you avoid delays.
Get a mortgage agreement in principle
Before you commit to anything, it's smart to get a mortgage agreement in principle. This gives you a clear idea of how much you can borrow and shows the developer that you're a serious buyer. In competitive developments, it can even give you an edge when reserving a property.
While this isn’t a formal mortgage offer, it’s a key early step that helps you move faster once you've chosen your home.
Choose a mortgage that suits new builds
Not all mortgage products are designed with new builds in mind. Some lenders offer shorter offer periods, which can be an issue if your home is still under construction. Others may have stricter criteria around flats, leaseholds, or homes bought off-plan.
Work with a mortgage advisor who understands the new build market. They’ll be able to guide you toward lenders who are familiar with developer timelines and can offer longer validity periods where needed.
Appoint a conveyancer with new build experience
Conveyancing for a new build is more complex than for an older property. Your solicitor or conveyancer will need to check things like planning permissions, road adoption agreements, service charges, and whether the property is freehold or leasehold.
Choose someone who has specific experience with new build purchases. They'll know what to look out for, understand the typical timescales, and be able to liaise effectively with the developer’s legal team.
Understand what happens at the exchange
Once your solicitor has reviewed the contract, carried out the necessary checks, and your mortgage is in place, you’ll be ready to exchange contracts. This is the point where the sale becomes legally binding, and you’ll typically pay your deposit.
After the exchange, your completion date will either be fixed or “on notice,” which means it will be confirmed once the property is finished and has passed its final inspection.

Step 4 - Understanding the property specifications and what’s included
One of the biggest advantages of buying a new build is that everything is, well, new. But not all new builds come with the same level of finish or inclusions. To avoid surprises later, it’s important to know exactly what’s included in your purchase and what will cost extra.
Fixtures, fittings and upgrade options
Every developer offers a standard specification, which usually covers basics like fitted kitchens, flooring in wet areas, and standard bathroom fittings. However, many offer the option to upgrade these elements for an additional cost. Think premium kitchen units, integrated appliances, carpet upgrades, or fitted wardrobes.
Make sure you receive a full specification list so you can see exactly what’s included in the price. Anything beyond that should be itemised and agreed upon before contracts are exchanged. Check out our full guide on whether new builds are worth it to weigh up the pros, cons, and everything in between.
Energy efficiency benefits
New build homes are built to modern efficiency standards. That means better insulation, double or triple glazing, and energy-saving boilers or heating systems. Most will come with a strong EPC (Energy Performance Certificate) rating, which can help lower your monthly running costs.
Some developments also offer additional features like solar panels, underfloor heating, or electric car charging points. These can add long-term value and align with more sustainable living.
Warranty protection
All reputable new build homes come with a structural warranty, often provided by the NHBC or similar bodies. These typically cover structural issues for 10 years, with the first two years often including a builder’s warranty for defects like plumbing, windows, or heating.
Appliances fitted by the developer may come with manufacturer warranties too, but you’ll usually need to register them yourself after completion.
Snagging
Even brand-new homes can have minor defects, known as snags. These might include things like scuffed paint, ill-fitting doors, or a dripping tap. Before you complete, or shortly afterwards, it’s worth carrying out a snagging inspection to list anything that needs fixing.
You can do this yourself or hire a professional snagging inspector. Most developers will fix any genuine issues identified within the initial warranty period, but having a clear list helps avoid back-and-forth later on.
Freehold or leasehold?
Ownership matters. Many houses are sold freehold, meaning you own the property and the land it sits on. Flat, and some houses in larger developments, may be leasehold, which means you own the property for a set number of years but not the land.
If you're buying leasehold, check the lease length, ground rent, service charges, and how these may increase over time. Your conveyancer should explain this clearly so there are no surprises later.
Step 5 - Pros, perks and practical considerations
Buying a new build offers more than just a fresh start. From the peace of mind provided by warranties to the opportunity to personalise your space before you move in, new homes come with unique advantages. That said, there are a few key points to keep in mind to ensure you get the most from your investment.
Are new builds worth it?
For many buyers, the answer is yes. Everything is brand new, meaning less maintenance and fewer unexpected repairs in the first few years. New builds also tend to be more energy-efficient, which can lead to lower running costs.
There’s no onward chain, which means fewer delays and less stress. And if you’re buying early in the development, you might even get a say in the layout, fixtures, or finishes, adding a personal touch before the home is complete.
Developer-fitted extras and upgrades
Many developers offer upgrade packages that can include premium flooring, integrated appliances, blinds, lighting, and even garden landscaping. These extras can make your home move-in ready without the need for further tradespeople or renovation work.
Just be clear on what's included in the base price and what counts as an upgrade. Ask for everything to be itemised before contracts are exchanged so there are no surprises later on.
Staying informed during the build
If you're buying off-plan, regular updates from the developer can help you track progress. Many provide estimated completion dates along with opportunities to visit the site at key stages.
Ask about your build’s timeline and how you'll be kept in the loop. Also, check whether your contract includes a long-stop date. This is the latest possible date the builder must complete the home, and it adds a layer of protection if the project runs behind schedule.
Long-term value and resale potential
New builds tend to hold their appeal with future buyers thanks to their energy efficiency, modern layouts, and low-maintenance design. Features like strong EPC ratings and structural warranties are attractive selling points.
While resale value depends on location, build quality, and market trends, well-maintained new builds often appeal to buyers looking for a home with fewer repair concerns and no need for renovation.
FAQs
How much deposit do I need for a new build?
Most buyers will need at least 5 to 10 per cent of the purchase price as a deposit. Some developers may ask for more, particularly if you’re buying off-plan. If you're using a scheme like Deposit Unlock, the minimum deposit could be lower, depending on the lender.
When buying a new build, when do you pay?
You typically pay a reservation fee to secure the property. Then, you’ll pay a deposit on exchange of contracts, usually within a few weeks. The remaining balance is paid on completion, once the home is complete and ready to move into.
Can I negotiate the price on a new build?
You can’t always reduce the asking price, but you can often negotiate extras. Developers may offer to cover stamp duty, include upgraded finishes, or offer cashback. It’s best to negotiate before paying the reservation fee.
Are new builds hard to sell?
Not necessarily. New builds can appeal to buyers looking for energy efficiency, modern layouts, and minimal maintenance. However, competition from newer properties nearby and local market trends can affect resale. Choosing a good location with strong demand helps retain value.
Is it harder to get a mortgage for a new build?
Some lenders have stricter criteria for new builds, especially for flats or off-plan homes. Offers may have shorter validity periods. Working with a broker who understands new builds can help you find lenders that fit your needs.
How do people afford new build homes?
Many use government-backed schemes such as First Homes, Own New, or Deposit Unlock. Developers may also offer financial incentives to help with upfront costs. Others may use equity from a current home or a gifted deposit.
Can you pull out of buying a new build?
Yes, but you may lose your reservation fee and could face additional costs if you’ve already exchanged contracts. If you’re unsure, speak to your solicitor before committing. Always check the terms of your reservation agreement.
Do you pay stamp duty on a new build house?
Yes, unless you're a first-time buyer eligible for relief, or the developer has agreed to cover it as part of an incentive. Your solicitor or mortgage advisor can help confirm how much you’ll need to pay.
How much do most builders require as a down payment?
Builders typically require 10 per cent of the purchase price as a deposit on exchange. If you’re buying with a government scheme or using Help to Buy ISA savings, your solicitor will help structure this correctly based on the funding method.
