Help to Buy Conveyancing UK: Buyer's Guide (2025)
We're not a law firm — we help you find the right legal support. For advice on your situation, speak to a legal adviser or find a solicitor.
Buying your first home is a big step, and if you are using one of the government's Help to Buy products to get there, the legal side can feel more complicated than a standard purchase. There are extra parties involved, extra paperwork, and rules that a general-purpose conveyancer may not deal with every day.
I have written this guide to pull apart what Help to Buy conveyancing actually involves, where buyers most often get stuck, and what you should be asking before you instruct anyone. My aim is to give you a plain-English overview so you walk into the process knowing roughly what to expect, rather than learning the rules of the game halfway through completion.
Whether you are looking at an Equity Loan property, using a Help to Buy ISA you opened years ago, or considering shared ownership, the legal mechanics matter.
Overview
Help to Buy conveyancing refers to the legal work carried out when purchasing a home using one of the government-backed Help to Buy products. It covers the same core tasks as any residential purchase, searches, title checks, contract review, exchange, and completion, but layers additional requirements on top.
Depending on which product you use, your conveyancer may need to liaise with Homes England or its administrator, register a second charge over the property in favour of the government, coordinate the release of bonus funds from an ISA provider, or handle the dual ownership structure that comes with a shared ownership lease. Each product brings its own forms, deadlines, and restrictions on what you can later do with the property.
Because of this, buyers often find it helps to work with a firm that regularly handles Help to Buy transactions rather than one that only occasionally touches them. Understanding the structure before you start can save delay later.
Key steps
- Work out which product fits. Before anything else, confirm which Help to Buy route applies to your purchase. The Equity Loan scheme has closed to new applications, but existing reservations and completions are still progressing. Shared ownership remains available through housing associations, and Help to Buy ISAs still pay out bonuses for account holders who opened in time.
- Get your mortgage agreement in principle. You will need a mortgage offer from a lender that accepts the specific Help to Buy product you are using. Not every lender participates in every scheme, so check this early. Your affordability will be assessed on the mortgage portion, and in Equity Loan cases, also against the combined borrowing.
- Instruct a conveyancer experienced with the scheme. Ask directly whether the firm handles Help to Buy transactions regularly. They will need to work with the scheme administrator, draft or review the right legal charges, and handle any builder deadlines, which are often tighter than a standard purchase timeline.
- Complete searches, enquiries, and contract review. Your conveyancer carries out local authority, drainage, and environmental searches, raises enquiries with the seller's solicitor, and reviews the draft contract and title. For new-builds, expect a longer contract pack and specific clauses covering build completion dates and long-stop dates.
- Exchange, complete, and register. On exchange you commit to the purchase and pay your deposit. On completion, funds flow from your lender, the scheme administrator where relevant, and you, to the seller. Afterwards, your conveyancer registers you at the Land Registry and registers any second charge in favour of the government.
Common questions
Q Is the Help to Buy Equity Loan still available?
The Equity Loan scheme closed to new applications some time ago, so you cannot start a fresh application today. However, buyers who reserved a qualifying property before the deadline have been working through to completion, and the legal rules around repayment and the second charge continue to apply for existing loans. If you already have an Equity Loan, the same framework governs any future sale or staircasing.
Q Can I use a Help to Buy ISA bonus on any property?
The bonus is intended for a first home purchase within certain price caps, which vary between London and the rest of the UK. The funds are released by your ISA provider to your conveyancer on completion, not on exchange, so the bonus cannot form part of your exchange deposit. Check the current eligibility rules with your ISA provider before assuming the bonus will apply.
Q How does shared ownership conveyancing differ from a normal purchase?
With shared ownership, you buy a share of the property and pay rent to the housing association on the remaining share. The legal structure is a long leasehold, and the lease contains specific provisions about staircasing, resale, and landlord consents. Your conveyancer will review these carefully, because they affect what you can do with the property long-term, including how and when you can sell.
Q How long does Help to Buy conveyancing usually take?
Timeframes vary, but Help to Buy purchases often take slightly longer than standard ones because of the extra parties involved. New-build Equity Loan purchases can move quickly once the property is ready, as builders typically set deadlines for exchange. Shared ownership purchases depend on the housing association's responsiveness. In many cases, allowing eight to twelve weeks from instruction is sensible.
Q Will I need a second charge on my property?
If you are completing an Equity Loan purchase, yes. The government takes a second legal charge over the property to secure the loan, which sits behind your main mortgage lender's first charge. Your conveyancer handles the registration of this at the Land Registry. It affects future remortgaging and sale, so you should understand how it works before you commit.
Q Can I remortgage a Help to Buy property later?
You can, but the process is more involved than a standard remortgage. Any remortgage usually needs the scheme administrator's consent, and not all lenders offer products that work alongside the Equity Loan second charge. Some borrowers use remortgaging as an opportunity to pay off part or all of the equity loan, which is called staircasing out. Take advice before committing to any route.
Q What happens if the builder misses the completion deadline?
New-build contracts typically include a long-stop date, which is the latest point by which the property must be ready. If that date passes without completion, you may have the right to withdraw and recover your deposit. Your conveyancer should explain these provisions clearly before exchange, as the practical position depends on the exact wording of the contract you are signing.
