Pitfall 1: Deposit at Risk — Not Held as Stakeholder
What Happens
When you exchange contracts, you pay a deposit (usually 5–10% of the purchase price). In a resale transaction, the deposit is normally held as 'stakeholder' — meaning the seller's solicitor holds it in a separate client account and cannot release it to the seller until completion.
Many new build contracts require the deposit to be released to the developer on exchange rather than held as stakeholder. This means the developer can use your money immediately.
Why It Is Dangerous
| Scenario | What Happens to Your Deposit |
|---|---|
| Developer completes on time | No problem — your deposit forms part of the purchase price |
| Developer goes into administration | Your deposit is lost. You become an unsecured creditor and may recover pennies in the pound, if anything |
| Developer cancels the contract (sunset clause) | Developer should refund your deposit, but if they are in financial difficulty, recovery may be slow or impossible |
Financial Impact
On a £300,000 property with a 10% deposit, you have £30,000 at risk. Even NHBC Buildmark deposit protection only covers up to £100,000 — and only if the developer is registered and the policy is in force.
How to Protect Yourself
| Action | Detail |
|---|---|
| Request stakeholder holding | Your solicitor should ask for the deposit to be held as stakeholder. The developer may refuse, but it is always worth requesting |
| Check warranty deposit protection | Confirm the warranty provider (NHBC, Premier Guarantee, LABC) offers deposit protection and what the limit is |
| Research the developer | Check Companies House for the developer's financial health. Look at recent accounts, any County Court Judgments, and whether they have a history of financial difficulties |
| Understand the risk | If the developer insists on deposit release and you proceed, do so with your eyes open — your solicitor should explain the worst-case scenario clearly |
Pitfall 2: Unadopted Roads and Sewers
What Happens
On a new development, the roads, pavements, streetlights, and sewers are initially owned and maintained by the developer. They are not automatically maintained by the local council or water company.
'Adoption' is the process by which the local authority (for roads, under Section 38 of the Highways Act 1980) and the water company (for sewers, under Section 104 of the Water Industry Act 1991) take over responsibility.
Why It Is a Problem
| Issue | Consequence |
|---|---|
| Roads not adopted | The developer or management company is responsible for repairs. If neither maintains them, the roads deteriorate and homeowners may face group repair bills |
| No Section 38 agreement in place | Without a formal adoption agreement, there is no legal obligation for the council to adopt the roads — they may never be adopted |
| Sewers not adopted | If sewers are not adopted by the water company, homeowners are responsible for maintenance and repair. Sewer repairs can cost thousands |
| Delays in adoption | Even with agreements in place, adoption typically takes 1–5 years after the development is completed. During this period, the management company or developer is responsible |
| Impact on resale | Buyers' solicitors will flag unadopted roads and sewers, which can delay or complicate future sales and may reduce property value |
How to Protect Yourself
| Action | Detail |
|---|---|
| Ask your solicitor to check | Your solicitor should confirm whether Section 38 and Section 104 agreements are in place before you exchange |
| Check the timeline | Ask when the developer expects adoption to be completed. Get this in writing if possible |
| Understand the interim arrangement | If adoption is pending, check who maintains the roads and sewers and how the costs are covered (usually through estate management charges) |
| Check your lender's position | Some mortgage lenders require adoption agreements to be in place before they will lend. Your solicitor checks this against the UK Finance Handbook |
Pitfall 3: Estate Management Charges
What Happens
Most new build developments have communal areas — roads, pavements, landscaping, play areas, drainage ponds, and green spaces — that are not maintained by the council. Instead, a management company is set up to maintain these areas, and homeowners pay an annual estate management charge.
The Problem
| Issue | Detail |
|---|---|
| Charges are often higher than expected | Estimates given at the point of sale (£100–£200/year) may bear little relation to actual charges once the development is complete (£300–£800+/year is common) |
| Charges can increase without limit | Most management company constitutions allow charges to increase annually. There is often no cap |
| Developer controls the management company initially | The developer typically appoints the management company and its directors. Homeowners may not gain control until the development is completed — which could be years |
| Enforcement powers | Under the Rentcharges Act 1977, the management company may have the power to take possession of your property if you fail to pay estate rent charges. This is an extreme measure but the legal right exists |
| Double taxation concern | You pay council tax AND estate management charges — effectively paying twice for some services (roads, lighting, landscaping) that would normally be council-maintained |
How to Protect Yourself
| Action | Detail |
|---|---|
| Get charge estimates in writing | Ask the developer for current year charges and projected charges for the next 5 years |
| Review the management company structure | Your solicitor should check the memorandum and articles of association — when do homeowners get a vote? When does control transfer from the developer? |
| Check what the charges cover | Get a breakdown of exactly what the charges pay for. Some charges cover genuinely necessary maintenance; others may seem excessive |
| Ask about adoption timeline | Once roads, sewers, and open spaces are adopted by the council, some management charges should reduce. Ask when this is expected |
| Factor charges into affordability | Include estate management charges in your monthly budget alongside mortgage, council tax, and insurance |
Pitfall 4: Ground Rent Traps on Older Leases
The Law Has Changed
The Leasehold Reform (Ground Rent) Act 2022 capped ground rent at a peppercorn (zero) for new residential leases granted after 30 June 2022. This means any new build flat or leasehold house purchased with a lease granted after this date should have no ground rent payable.
Why It Still Matters
| Scenario | Risk |
|---|---|
| Buying a new build completed before June 2022 | Properties completed and sold before the Act came into force may still have ground rent clauses — including escalating ground rents that double every 10–25 years |
| Buying a nearly new property (resale within 2–5 years) | The original lease may predate the 2022 Act and contain ground rent provisions. The Act only applies to new leases, not existing ones |
| Shared ownership | Shared ownership leases have transitional arrangements. Check whether your shared ownership lease has ground rent and whether it is subject to the 2022 Act |
How to Protect Yourself
| Action | Detail |
|---|---|
| Confirm peppercorn ground rent | For any new lease, your solicitor should confirm the ground rent is peppercorn. If it is not, the lease is non-compliant with the 2022 Act |
| Check existing leases carefully | If buying a nearly new leasehold property, check the ground rent provisions — especially escalation clauses |
| Understand the impact | High or escalating ground rents can make a property unmortgageable, unsellable, or significantly less valuable |
Pitfall 5: Restrictive Covenants You Did Not Expect
What Happens
New build properties come with restrictive covenants written into the transfer deed. These are permanent obligations that bind you and future owners.
Common Restrictive Covenants on New Builds
| Covenant | What It Means | Impact |
|---|---|---|
| No alterations to exterior | Cannot change windows, doors, roof, or external appearance without developer/management company consent | Cannot add an extension, conservatory, or even change your front door colour without permission |
| No commercial vehicles | Cannot park commercial vehicles (vans, trucks) on the driveway or street | Problem if you are a tradesperson or run a business requiring a van |
| No business use | Property must be used as a private dwelling only | May restrict working from home in some interpretations, though most relate to visible business activity |
| Fencing requirements | Specific type, height, and colour of fencing required | Cannot replace fencing with hedging or different style |
| No satellite dishes on front elevation | Satellite dishes only permitted at rear | May affect TV/broadband options depending on property orientation |
| Maintenance obligations | Must maintain the property, garden, and driveway to a certain standard | Management company can enforce if your property falls below standards |
| No subdivision | Cannot divide the property into multiple dwellings | Cannot convert to flats or add a separate annexe for rental |
How to Protect Yourself
Your solicitor should list every restrictive covenant in their report to you. Read them carefully and consider whether you can live with them long-term. Once you exchange, you are bound by them permanently.
Pitfall 6: Developer Insolvency
What Happens
If the developer enters administration or liquidation before completing your property, several things are at risk.
| What Is at Risk | Outcome |
|---|---|
| Your deposit (if released) | You are an unsecured creditor. Recovery is uncertain and can take years |
| Completion of your property | Construction may stop. The warranty provider may arrange for another builder to complete the work, but this takes time |
| Development completion | Communal areas, roads, landscaping may be left incomplete. Adoption agreements may not be honoured |
| Warranty obligations | The developer's 2-year builder warranty becomes worthless. The warranty provider's insurance (years 3–10) remains valid |
| Snagging and defects | No one to fix defects during the builder period. You may need to arrange and pay for repairs yourself, then claim on the warranty |
How to Protect Yourself
| Action | Detail |
|---|---|
| Check developer finances | Companies House shows the developer's latest accounts, any charges (loans) on the company, and filing history |
| Insist on stakeholder deposit | If the deposit is held as stakeholder, it is protected even if the developer goes bust |
| Confirm warranty deposit protection | NHBC Buildmark includes deposit protection up to £100,000. Check your warranty provider's equivalent |
| Use a reputable developer | Larger, established developers are less likely to become insolvent. Smaller developers may offer better value but carry higher risk |
Pitfall 7: Section 106 Surprises
What Happens
Section 106 agreements are obligations imposed on developers by local planning authorities as a condition of planning permission. They require the developer to provide community benefits — affordable housing, school contributions, transport improvements, open spaces — in exchange for the right to build.
How It Can Affect You
| Section 106 Issue | Impact on You |
|---|---|
| Affordable housing quotas | Some plots on the development may be restricted to affordable or social housing. This does not affect your property directly but may affect the development's character |
| Resale restrictions | Some Section 106 agreements restrict who can buy certain properties (local connection tests, first-time buyer restrictions). If your property has such a restriction, it limits your future buyers |
| Open space obligations | The developer may be required to provide and maintain open spaces for a set period. If they fail, the obligation may fall to the management company — and ultimately to you |
| Infrastructure contributions | Contributions towards schools, roads, or healthcare facilities are usually the developer's obligation, but check they do not flow through to homeowners |
How to Protect Yourself
Your solicitor should obtain and review the Section 106 agreement and check whether any obligations affect your specific plot. Most obligations are the developer's responsibility, but it is essential to confirm this.
Pitfall 8: Specification Changes After Exchange
What Happens
You exchange contracts based on a specification document showing the materials, finishes, fixtures, and layout of your property. After exchange, the developer substitutes some items — different kitchen units, cheaper bathroom fittings, alternative flooring — claiming they are 'equivalent or better' as permitted by the contract.
The Problem
| Developer's Claim | Reality |
|---|---|
| 'Equivalent or better' | 'Equivalent' is subjective. A developer may consider a different brand equivalent even if the buyer would not |
| 'Minor variation' | What constitutes 'minor' is not defined in most contracts. A different kitchen layout could be considered minor by the developer |
| Supply chain issues | Developers genuinely face supply chain problems. But the solution should not be a downgrade at the buyer's expense |
How to Protect Yourself
Before exchange, your solicitor should check the specification variation clause carefully. Push for specific protections on key items (kitchen brand and range, bathroom suite, flooring type). Document any extras or upgrades you have paid for in the contract. For detailed contract guidance, see our contract checking guide.
Pitfall 9: Completion Delays and No Compensation
What Happens
The developer gives you an estimated completion date. You make arrangements — give notice on your rental, book removals, take time off work. The completion date is then pushed back by weeks or months.
Financial Impact
| Cost | Amount |
|---|---|
| Extended rental | £800–£2,500/month depending on location |
| Storage fees | £100–£300/month |
| Mortgage offer extension | Usually free for the first extension, but may trigger re-valuation (£200–£400) |
| Cancelled removal rebooking | £200–£500 if you lose a deposit and need to rebook |
| Temporary accommodation | If between properties, hotels or short lets can cost £1,000–£3,000+/month |
| Emotional stress and disruption | Unquantifiable but very real |
How to Protect Yourself
| Action | Detail |
|---|---|
| Check the longstop date | This is your ultimate protection — if the developer misses the longstop date, you can withdraw and recover your deposit |
| Do not give notice early | Do not give notice on your rental or sell your existing home until your solicitor confirms a firm completion date |
| Check compensation provisions | The Consumer Code may entitle you to reasonable compensation for delays, but this depends on the contract terms |
| Build in contingency | Plan for a 2–4 week delay as a realistic contingency |
Pitfall 10: Leasehold Houses
What Happens
Some developers sell new build houses on long leasehold terms rather than freehold. While this was more common before 2022, it still occurs in some cases.
Why It Matters
| Issue | Impact |
|---|---|
| Ground rent (pre-June 2022 leases) | You may owe annual ground rent to the freeholder. Escalating ground rents on older leases can become unaffordable |
| Permission to alter | You need the freeholder's consent for extensions, conversions, or significant alterations — and may need to pay for it |
| Lease length diminishes | As the lease shortens, the property becomes harder to mortgage and less valuable. You may need to extend the lease at significant cost |
| Future sale complications | Leasehold houses are less attractive to buyers than freehold. Some lenders will not lend on leasehold houses |
| Freehold purchase | You have the legal right to buy the freehold ('enfranchisement') but this costs money and requires a legal process |
How to Protect Yourself
For new build houses, expect freehold tenure. If a developer offers a house on a leasehold basis, ask why and consider whether freehold alternatives are available. Your solicitor should flag leasehold houses as unusual and advise on the implications.
Pitfall 11: Missing or Inadequate Warranty
What Happens
Not all new builds come with an NHBC Buildmark warranty. Some developers use alternative warranty providers, and a small number of properties (self-builds, small developments) may have no warranty at all.
Why It Matters
| Situation | Risk |
|---|---|
| No warranty | No protection against structural defects. No deposit protection. Most lenders will not lend without an acceptable warranty |
| Unknown warranty provider | Your mortgage lender may not accept the warranty, blocking your purchase |
| Warranty not in force at exchange | If the warranty documentation is not finalised before exchange, you may not be covered if something goes wrong before completion |
How to Protect Yourself
Your solicitor should confirm the warranty provider is on your lender's approved list before exchange. Acceptable providers typically include NHBC, Premier Guarantee, LABC, Checkmate, Global Home Warranties, ICW, Protek, and several others listed in the UK Finance Handbook.
Pitfall 12: Not Using an Independent Solicitor
What Happens
The developer recommends a solicitor — often one who is on their 'panel' and processes their transactions regularly. You use this solicitor because it seems convenient and may be slightly cheaper.
The Risk
| Concern | Detail |
|---|---|
| Conflict of interest | The solicitor relies on a steady stream of referrals from the developer. Challenging the developer's contract aggressively could jeopardise that relationship |
| Speed over thoroughness | Developer-panel solicitors are often chosen because they process transactions quickly — which may mean less time scrutinising your contract |
| Limited pushback | An independent solicitor has no relationship with the developer to protect and is more likely to flag issues and push for amendments |
How to Protect Yourself
The Consumer Code for Home Builders requires that you have access to independent legal advice. Choose your own solicitor — one who is experienced in new build conveyancing but has no relationship with the developer. For guidance on selecting the right solicitor, see our choosing a solicitor guide.
Pitfall 13: Planning Conditions Not Satisfied
What Happens
Planning permission for the development may come with conditions — landscaping must be completed, parking spaces provided, certain materials used, noise mitigation installed, or community facilities built. If these conditions are not satisfied, the local authority can take enforcement action.
How It Affects You
| Scenario | Impact |
|---|---|
| Outstanding planning conditions | The development may not be fully lawful until conditions are discharged. This could affect future development, extensions, or your ability to sell |
| Developer not complying | If the developer does not complete required works (e.g., landscaping, community facilities), the council may take action that disrupts the development |
| Building regulations not signed off | If the building control body has not issued a completion certificate, there may be questions about whether the property meets required standards |
How to Protect Yourself
Your solicitor checks the planning permission and any conditions attached. They should confirm that key conditions have been discharged or will be discharged before completion. A building regulations completion certificate should be available at completion.
Pitfall 14: Mortgage Valuation Below Purchase Price
What Happens
Your mortgage lender instructs a surveyor to value the property. The surveyor values it below the purchase price. The lender will only advance a mortgage based on the lower valuation, leaving you with a shortfall.
The Numbers
| Scenario | Calculation |
|---|---|
| Purchase price | £350,000 |
| Surveyor valuation | £330,000 |
| Mortgage (90% LTV) | 90% of £330,000 = £297,000 (not 90% of £350,000 = £315,000) |
| Shortfall you must fund | £350,000 – £297,000 = £53,000 (instead of £35,000 deposit) |
| Extra cash needed | £18,000 more than planned |
How to Protect Yourself
| Action | Detail |
|---|---|
| Negotiate with the developer | Ask the developer to reduce the price to match the valuation. Some developers will agree rather than lose the sale |
| Challenge the valuation | Your broker can submit comparable evidence to the lender to support a higher valuation |
| Fund the difference | If you have the cash, you can pay the shortfall yourself — but this increases your effective deposit |
| Be cautious about incentives | Large incentives (above 5% of price) can flag to the surveyor that the property is overpriced, increasing the risk of a down-valuation |
Pitfall 15: Buying Without Understanding Ongoing Costs
What Happens
Buyers focus on the purchase price and deposit but overlook the ongoing costs specific to new build properties.
Ongoing Costs Often Missed
| Cost | Typical Annual Amount | Notes |
|---|---|---|
| Estate management charge | £200–£800 | For maintenance of communal areas, unadopted roads, landscaping |
| Service charge (leasehold) | £1,500–£4,000+ | Building insurance, maintenance, communal cleaning, lift servicing |
| Ground rent (pre-2022 leases) | £0–£500+ | New leases post-June 2022 should be peppercorn (zero) |
| Management company membership | Included in estate charge | You are a member and bound by the company's rules |
| Higher energy costs during drying-out | £200–£500 extra in year 1 | New builds need extra heating in the first year to dry out moisture from construction |
| Furnishing an empty property | £5,000–£25,000 | New builds come empty — you need everything from curtains to garden fencing |
How to Protect Yourself
Get written estimates of all ongoing charges before exchange. Factor them into your monthly budget alongside your mortgage payment and council tax. For a comprehensive cost breakdown, see our moving costs guide.

Frequently Asked Questions
Which legal pitfall is the most dangerous?
Deposit exposure from release to the developer (Pitfall 1) combined with developer insolvency (Pitfall 6) represents the highest financial risk — you could lose tens of thousands of pounds with limited recourse. Insist on stakeholder holding or confirm warranty deposit protection covers your full deposit amount.
Can my solicitor prevent all these pitfalls?
A good solicitor can identify every pitfall on this list and advise you on the risks. They cannot always prevent them — developers rarely agree to contract amendments. But awareness and informed decision-making are your best protection. See our guide to why you need a new build solicitor.
Are estate management charges avoidable?
On most new build developments, no — they are a condition of buying on the estate. You can choose developments without management companies (look for estates where all roads and spaces are adopted by the council from day one), but these are uncommon. Once on an estate, you can work to control charges by getting involved in the management company once it transfers to homeowner control.
What if I discover a legal problem after I have already completed?
Your options depend on the problem. For construction defects, the warranty provides protection. For contract-related issues, you may have a claim against the developer under the contract or consumer protection law. For conveyancing failures, you may have a claim against your solicitor under their professional indemnity insurance. Act quickly — legal claims have time limits (typically 6 years for contract claims).
Should I get a survey on a new build?
A traditional homebuyer survey is less relevant for a new build, but a professional snagging inspection (£300–£600) is highly recommended. A snagging inspector checks the property for defects before or shortly after completion, giving you a detailed list to submit to the developer. See our handover and inspection guide.
Do these pitfalls apply in Scotland?
Most apply in Scotland with some differences. Scotland uses missives instead of exchange contracts, has LBTT instead of SDLT, and does not have leasehold for houses (abolished under Scots law). Estate management charges and developer insolvency risks apply equally. Always use a Scottish solicitor experienced in new build purchases for Scottish transactions.
