Mortgage to Buy Land UK: Finance With or Without Planning Permission

The land finance market comprises several distinct product categories, each suited to a different buyer profile and intended use. Identifying which product applies to your situation before approaching lenders will save time and avoid declined applications.

Agricultural mortgages are long-term products designed for farmland, smallholdings, and grazing land. Specialist agricultural lenders assess the productive value of the land alongside the borrower's farming income or business plan. Rates start from around 5.5% p.a. with LTVs up to 65%, and terms of up to 25 years are available from some providers.

Specialist land mortgages are term products for residential development plots and commercial land where planning permission exists or is anticipated. They are offered by challenger banks and specialist lenders rather than high-street banks. Terms typically run from 1 to 10 years, with interest rates ranging from 6–9% p.a. depending on planning status, LTV, and borrower profile.

Bridging loans are short-term facilities used when speed is critical — particularly for land purchased at auction, where completion is typically required within 28 days. For a detailed comparison of how these short-term products compare to longer-term development facilities, see our guide on development finance vs bridging loans.

Development finance combines the land acquisition cost and construction costs in a single facility, with funds drawn in stages as build progresses. For developers who intend to break ground within 6–12 months of acquisition, this is often more efficient than taking a standalone land mortgage and then refinancing into a development loan at a later stage.

Planning permission is the single most important variable in land finance. Lenders treat land with full planning permission very differently from land with only outline consent or no planning at all. The difference shows up directly in the LTV available, the interest rate applied, and the number of lenders willing to consider your application.

Land without any planning permission — sometimes described as hope value land — is the hardest to finance. Very few specialist lenders will lend against it. Those that do typically cap LTV at 50% and price the risk accordingly. Personal guarantees and additional collateral are frequently required. If the land has no clear development potential or productive agricultural use, some lenders will decline entirely regardless of the borrower's financial strength.

Outline planning permission signals that development is viable in principle. This materially improves lender appetite — LTVs can reach 55–65% from specialist lenders — but detailed planning can still be refused or conditions attached, so lenders apply caution and higher rates than they would for land with detailed consent already secured.

Full planning permission, known as detailed consent, gives lenders the most comfort. With full planning in place, LTVs of up to 65–70% become achievable, and — critically — the land becomes eligible for development finance as well as a standalone land mortgage. This is when you have the broadest choice of lender and the strongest position to negotiate terms.

It is also worth understanding the impact planning permission has on land value itself. Outline planning consent regularly doubles or trebles the value of a site, which changes the security position for any lender. If you buy land and intend to apply for planning during the mortgage term, ensure your solicitor reviews any restrictions in the facility agreement — some lenders require consent before planning applications are submitted.

The deposit required to buy land is substantially higher than on a standard residential purchase. The table below summarises typical LTV ratios and minimum deposit requirements by planning status and land type:

Lenders calculate LTV against the lower of the purchase price and the independent surveyor's valuation. If you are paying a price above current market value — for example, paying a premium that reflects anticipated planning uplift — the lender will value the land at its present state, not its hoped-for future value. Your effective LTV will be lower than the headline figure, and you may need a larger deposit than you initially planned.

Interest rates on land mortgages are materially higher than on residential mortgages, reflecting the increased risk that bare land presents as security. For a specialist term land mortgage on land with full planning permission, expect rates in the range of 6–9% p.a. For bridging loans against land, rates typically run at 0.75–1.5% p.m.

Beyond the headline interest rate, a typical land finance transaction involves the following additional costs:

Lenders assess land mortgage applications on a broader set of criteria than a standard residential mortgage. The key factors are: the borrower's financial strength and credit history; development experience, which is particularly important for development plots; the planning status and intended use of the land; market demand and saleability of the land type in that location; and an independent valuation confirming current market value.

Developers with a demonstrable track record of completing schemes of similar scale — whether new build housing, conversions of office blocks into residential use, or mixed-use projects — are viewed considerably more favourably by specialist lenders. Thorough due diligence on the title, planning history, and any restrictive covenants should be completed before you exchange contracts: lenders will expect their valuer and solicitor to raise the same questions, and surprises at the legal stage are a common cause of delayed drawdowns. If this is your first land purchase, working with a broker who has established relationships across a wide lender panel — and can frame your application appropriately — materially improves your chances of securing terms.

Beyond the interest rate and deposit, a number of additional costs shape the total cost of borrowing on a land mortgage loan. Budgeting for these accurately up front avoids unexpected cash calls on completion.

Typical costs include a lender arrangement fee of 1–2% of the loan, a specialist land valuation (often £1,500–£5,000 depending on acreage and complexity), lender legal fees (from £1,500 upwards), and the borrower's own solicitor costs. Where the land mortgage is short-term bridging, interest is often retained or rolled into the loan rather than serviced monthly, which reduces the net advance and should be modelled in the cashflow.

Stamp Duty Land Tax applies to land purchases in England and Northern Ireland using the non-residential rates: 0% on the first £150,000, 2% up to £250,000, and 5% above that threshold. Wales applies Land Transaction Tax and Scotland uses Land and Buildings Transaction Tax — both with their own non-residential bands. SDLT is not lent against by most land finance providers, so it must typically be funded from borrower cash.

Refinancing a land mortgage is common. A bridging loan taken to acquire land without consent is usually refinanced on grant of planning permission, either onto a term mortgage or into a development finance facility that rolls in the construction cost. Where the original loan was an agricultural or long-term commercial mortgage, borrowers may refinance at the end of a fixed period to secure a better rate or release equity, subject to the new lender's valuation and the borrower's updated financial position.

For many UK developers, a standalone land mortgage is not the most efficient structure. Depending on your intended use and timeline, a bridging loan or development finance facility may offer better gearing, lower total cost, or greater flexibility — particularly when a build programme is planned within 12–18 months of acquisition.

Bridging loans are almost always the right choice for auction purchases. Auction completions in the UK typically take place within 28 days of the fall of the hammer — far too short for most term mortgage applications to complete. A bridging loan can complete in 5–10 working days, allowing you to secure the land and refinance onto a longer-term product or draw down development finance once planning is in place or construction commences.

Development finance is often the most cost-effective structure when you plan to break ground quickly. Many development finance lenders will fund up to 65% of the land cost and 100% of the build cost within a single combined facility, subject to the gross loan not exceeding 65–70% of Gross Development Value (GDV). Understanding your GDV accurately before choosing a funding structure is therefore essential — see our guide on how to calculate GDV for a full explanation of the methodology.

The choice between mainstream bank products and specialist lenders also carries significant implications for land finance. High-street banks rarely accommodate land-only purchases; the lenders who actually serve this market are specialist and challenger lenders with more flexible underwriting criteria and faster processes. For a detailed comparison of how these lenders differ on terms, appetite, and turnaround times, see our guide on bank vs specialist development finance.

For more complex projects — such as a large brownfield site with outline planning where the development will be phased over several years — a combination of products may be appropriate: a land mortgage to hold the site, followed by development finance drawn down tranche by tranche as each phase commences. Structuring this correctly at the outset avoids costly mid-project refinancing. Drawing on Matt's 25+ years of experience and a panel of over 100 lenders, Construction Capital can help identify the right structure before you commit to a purchase.

Yes, you can get a mortgage for a plot of land to build your own home: a self-build mortgage funds the plot and then releases money in stages as the build progresses, usually with a deposit of 25% or more and ideally with planning permission in place. Because the home will be your residence, this is regulated lending and must be arranged through an FCA-authorised mortgage adviser.

The application process for a land mortgage loan is more involved than a residential mortgage application. Lenders require a detailed picture of the asset, the borrower, and the intended use of the land before they will issue a credit-backed terms letter.

Before approaching lenders, assemble the following: title register and plan from HM Land Registry confirming ownership and boundaries; a copy of any planning permissions, conditions, and decision notices; a valuation from a RICS-qualified surveyor with experience in development land; a brief business plan or statement of intent covering the proposed use, timeline, and exit strategy; evidence of the borrower's financial position (net worth statement, last two to three years of accounts if borrowing via a company); and details of any existing debt secured against the asset or related assets.

Approaching multiple lenders directly is time-consuming and can result in multiple hard credit searches, which damage your credit profile. Working with a specialist broker with a panel of 100+ lenders — including the specialist lenders who actually hold appetite for land — allows the case to be presented in its best light to the most suitable funders simultaneously.
