Why Pre-Reservation Checks Are Essential

Reserving a new build home is one of the most exciting steps on the property ladder, but it is also a moment that deserves careful preparation. A reservation fee — typically between £500 and £1,000 — secures a specific plot and takes it off the market while your solicitor begins the conveyancing process. While this sum is modest compared to the overall purchase price, the commitment it represents is significant: once you reserve, the clock starts ticking on exchange deadlines, mortgage applications, and legal searches.

Too many buyers rush into reserving a plot after a single visit to a show home, only to discover issues later that could have been identified with a little upfront research. From unchecked planning permissions to unclear specifications, the consequences of skipping due diligence can range from costly surprises to a failed purchase altogether.

This guide walks you through every critical check you should complete before handing over your reservation fee. Whether you are a first-time buyer or an experienced homeowner, these steps will give you the confidence that you are making a sound investment in the right property, with the right developer, at the right time.

Consumer Code cooling-off period

The Consumer Code for Home Builders provides important protections for new build buyers, including a cooling-off period. However, relying on the cooling-off period as your safety net is not ideal — it is far better to do your homework before committing. Let us look at what you need to check, starting with the developer themselves.

Checking the Developer’s Reputation and Track Record

The developer building your home is, in many ways, as important as the home itself. Their reputation, financial stability, and build quality will determine your experience from reservation through to completion and beyond. Before you commit to a reservation, here is how to evaluate the developer thoroughly.

What to Research About the Developer

  • NHBC registration: Check that the developer is registered with the National House Building Council (NHBC) or another approved warranty provider such as LABC Warranty or Premier Guarantee. NHBC-registered builders must comply with strict build standards and provide a 10-year Buildmark warranty.
  • Consumer Code membership: Confirm the developer is a member of the Consumer Code for Home Builders. This is a legal requirement for NHBC-registered builders and provides you with protections including pre-purchase information rights and a dispute resolution service.
  • HBF Star Rating: The Home Builders Federation (HBF) conducts an annual customer satisfaction survey. Developers are rated from one to five stars based on the percentage of buyers who would recommend them. Look for 4-star or 5-star rated builders for the best experience.
  • Trustpilot and Google Reviews: Search for reviews from actual buyers on the specific development you are considering, not just the developer overall. Pay attention to comments about build quality, communication, aftercare, and snagging response times.
  • Previous developments: If possible, visit a completed development by the same builder. Speaking to existing residents can give you invaluable insight into build quality, estate management, and any ongoing issues.
  • Financial stability: For larger purchases, it is worth checking the developer’s financial health via Companies House. Look at their most recent annual accounts to confirm they are solvent and have the resources to complete the development.
  • Awards and accreditations: Recognitions from bodies such as the NHBC Pride in the Job awards, LABC Building Excellence Awards, or WhatHouse? Awards are positive indicators of build quality and design standards.

Taking time to choose the right developer is one of the most important steps in the entire process. A reputable builder will be transparent about timelines, specifications, and any potential issues with the development. If a developer is reluctant to answer questions or provide documentation, treat that as a red flag.

Planning Permissions and Build Stage

Understanding the planning status and current build stage of a development is critical before you reserve. These factors affect everything from your completion timeline to the certainty that the home will be built as advertised.

Planning Permission Checks

Every new build development requires planning permission from the local planning authority. Before reserving, verify the following:

  1. Full planning permission granted: Check that the development has full (detailed) planning permission, not just outline permission. Outline permission establishes the principle of development but does not confirm the exact design, layout, or number of homes. You can check planning applications on the local council’s planning portal.
  2. Reserved matters approved: If the development was initially granted outline permission, confirm that all reserved matters (appearance, landscaping, layout, scale, and access) have been approved.
  3. Section 106 agreements: These are legal agreements between the developer and the council that may require the developer to provide affordable housing, contribute to local infrastructure, or maintain open spaces. Understanding these obligations helps you anticipate the finished development.
  4. Conditions attached: Planning permissions often come with conditions that must be met during construction, such as noise restrictions, working hours, or ecological requirements. These conditions are public record.
  5. Planning history: Check whether there have been any amendments to the original planning permission, especially those affecting the number of homes, building heights, or the design of the specific plot you are interested in.

Build Stage Considerations

The stage of construction when you reserve has significant implications for your purchase. Here is what to expect at each stage:

Build StageWhat You Can SeeKey ConsiderationsTypical Wait
Off-plan (pre-construction)Site plans, CGIs, show home (different plot)Maximum customisation options; longest wait; rely on plans12–24 months
Foundations & groundworksFootings, drainage, site layoutSome customisation possible; can verify plot position9–18 months
Superstructure (walls up)External walls, roof structureLimited layout changes; can assess brickwork quality6–12 months
First fix (internal work)Plumbing, electrics, plasteringVery limited changes; can see real room sizes3–6 months
Second fix & finishingKitchens, bathrooms, decoratingMinimal changes; can assess actual finishes1–3 months
Completed (ready to move in)Finished homeNo customisation; fastest completion; what you see is what you getImmediate–4 weeks

If you are buying off-plan or at an early stage, make sure you have a clear understanding of the expected completion date and any contractual provisions if there are delays. Ask the sales team for a written build programme showing key milestones.

Understanding the site plan is equally important. Request a copy of the full site layout showing your plot in context — including neighbouring properties, roads, parking areas, green spaces, and any future phases that may involve further construction.

Specifications, Finishes, and Included Features

The specification of a new build home is the detailed list of everything that is included in the purchase price. This is one of the most important documents you will review before reserving, as it defines exactly what you are buying. Never assume that features shown in the show home are standard — many are paid upgrades.

Key Specification Areas to Review

  • Kitchen: Brand and range of units, worktop material (laminate, quartz, or granite), appliances included (typically oven, hob, extractor — but check if fridge, dishwasher, or washer are included), number of units, and whether an island or peninsula is standard or an upgrade.
  • Bathroom and en-suite: Sanitaryware brand, bath type (steel or acrylic), shower type (over-bath, separate enclosure, walk-in), tiling extent (full-height or half-height), and heated towel rails.
  • Flooring: Many new builds come with basic flooring in wet areas only, leaving bedrooms and living spaces as bare chipboard. Check what is included and budget for additional flooring if needed.
  • Heating: Type of boiler or heat pump system, radiator specifications, smart thermostat inclusion, and underfloor heating (if applicable).
  • Windows and doors: Double or triple glazed, uPVC or aluminium frames, colour, and security features. Also check the specification of external doors, including any bi-fold or French door options.
  • Electrical: Number of sockets per room, USB charging points, lighting specification (downlights, pendant points), TV and data points, and provision for smart home systems.
  • External features: Turf or seed for the garden, fencing type and height, driveway surface material, and any allocated parking or garage provision.
  • Warranties and guarantees: Confirm the structural warranty provider (NHBC, LABC, or similar) and any manufacturer warranties on appliances and systems.

Show Home vs Standard Specification

Show homes are designed to showcase the best version of a property, and they frequently include upgraded finishes, furniture, and accessories that are not part of the standard specification. When viewing a show home, ask the sales advisor to clearly point out which features are upgrades and which are included as standard. Better still, request a home demonstration of an actual completed plot to see the standard finish in reality.

Common show home upgrades that may not be standard include:

  • Quartz or granite worktops (laminate may be standard)
  • Integrated appliances beyond oven, hob, and extractor
  • Full-height tiling in bathrooms
  • Upgraded carpet or engineered wood flooring
  • Feature lighting and additional downlights
  • Built-in wardrobes
  • Bi-fold doors to the garden
  • Landscaped garden with paving and planting

Financial Readiness: Are You Prepared to Reserve?

Reserving a new build sets a chain of financial commitments in motion. Before you pay the reservation fee, make sure your finances are in order to avoid delays or the risk of losing your fee.

Prioritise the top three items before paying any reservation fee. The remaining items should be addressed before exchange.

Mortgage Agreement in Principle (AIP)

A mortgage agreement in principle (also called a decision in principle) confirms that a lender is willing to lend you a specific amount based on your income and circumstances. Having an AIP before you reserve demonstrates to the developer that you are a serious, financially qualified buyer and reduces the risk of your purchase falling through.

Key points about your AIP:

  • An AIP is typically valid for 60 to 90 days — make sure it will not expire before you need to exchange contracts
  • The AIP amount should comfortably cover the purchase price minus your deposit
  • If buying with a shared ownership or other government-backed scheme, confirm the lender supports these products
  • Some new build lenders offer extended validity periods for off-plan purchases where completion is many months away

Understanding Your Full Costs

Beyond the purchase price, ensure you have budgeted for all associated costs. Many buyers underestimate the total expenditure involved in buying a new build home:

Cost ItemTypical AmountWhen Payable
Reservation fee£500 – £1,000At reservation
Exchange deposit5–10% of purchase priceAt exchange of contracts
Solicitor fees£1,000 – £2,500Staged, balance at completion

Frequently Asked Questions

Is the reservation fee refundable if I change my mind?

During the cooling-off period (typically 14 days under the Consumer Code for Home Builders), yes — your reservation fee is fully refundable if you withdraw for any reason. After the cooling-off period, the fee is generally non-refundable unless specific conditions in the reservation agreement are met, such as your mortgage application being formally declined. Always check the exact refund terms in your reservation agreement before signing.

How long do I have to exchange contracts after reserving?

Most developers set an exchange deadline of 28 days from the date of reservation, though some allow up to 56 days for more complex transactions. If you need more time — for example, if you are selling an existing property — discuss this with the sales team before reserving. Some developers offer part exchange schemes that can simplify and speed up the process.

Can I negotiate the reservation fee?

The reservation fee itself is rarely negotiable, as it is a standard administrative charge. However, you can often negotiate other aspects of the purchase, including the overall price, included upgrades, contribution to legal fees, or flooring packages. See our guide to negotiating new build incentives for strategies that work.

What happens if the developer delays completion?

Your contract should include a longstop date — the absolute latest date by which the developer must complete the home. If the developer fails to meet this date, you are entitled to withdraw from the purchase and receive a full refund of your deposit and reservation fee. Delays short of the longstop date are typically covered by contractual provisions for notice and extended completion windows. Your solicitor will explain these terms during the buying process.

Should I get an independent snagging survey before completion?

While a snagging survey is not required before reservation, it is highly recommended before legal completion. An independent snagging inspector will identify defects and issues that the developer must rectify under the terms of your warranty. Many buyers arrange a pre-completion snagging inspection and submit the list to the developer before moving in, ensuring issues are addressed promptly.

Reserve With Confidence

Reserving a new build home should be an exciting and positive experience, not a source of anxiety. By working through the checks outlined in this guide — from verifying the developer’s reputation and planning permissions to reviewing specifications and getting your finances in order — you will be in the strongest possible position when you hand over that reservation fee.

Remember the golden rule: never reserve under pressure. A good developer will give you the time and information you need to make a confident decision. If you feel rushed or if questions go unanswered, that tells you something important about the buying experience ahead.
