Mortgage on Land: How to Finance a Plot, Paddock or Building Land

A mortgage on land is a loan secured against a plot or parcel of land rather than a finished house. Yes, you can get one in the UK, but not from a standard residential lender. Depending on the land and its planning status, you use a self-build mortgage, a land bridging loan, development finance or an agricultural mortgage, typically at 50% to 80% loan to value.

Buying a working farm or smallholding? That is agricultural lending, covered in our agricultural mortgage guide.

The single biggest factor is planning permission. A building plot with detailed consent can be financed at up to 80% of the purchase price through a self-build lender. Bare land with no planning is usually capped at around 50% by the few specialists that touch it, and some lenders will not lend on it at all. This guide maps every type of land to the product that actually finances it, names lenders with their published criteria, explains planning uplift, shows how land you already own can become your self-build deposit, sets out stamp duty on land in England, Scotland and Wales, and works through a full plot purchase with the arithmetic shown.

Can you get a mortgage on land in the UK?

Yes, you can get a mortgage on land in the UK, but the lender and product depend on what the land is for. High street residential mortgages are designed for a habitable dwelling that a lender can repossess and sell quickly. Bare land does not fit that model: it produces no rent, it is harder to value, and it can take months or years to sell. So mainstream products such as a standard residential or buy-to-let mortgage will not lend on it.

Instead, the market splits into four routes. Building society self-build mortgages lend on plots with planning where you will build your own home. Bridging lenders fund land purchases short term, usually 3 to 24 months, while planning is obtained or a longer-term loan is arranged. Development finance lenders fund land plus construction for developers building to sell. Agricultural lenders, mostly the big banks’ farming teams, lend on working farmland over long terms. There is also a fifth category, amenity land and paddocks with no development prospect, which most lenders decline and buyers usually fund in cash or by borrowing against another property.

How is each type of land financed?

Each type of land is financed by a different product, and the table below is the fastest way to see which one fits. The deciding questions are always the same: does the land have planning permission, what will be built or done on it, who will live there, and how will the loan be repaid. A plot with consent for a house you will live in is a self-build case. The same plot bought by a developer to build and sell is development finance. Land with no consent is a bridging or cash purchase until planning is granted.

LTV ranges are typical market ranges from Knox’s lender panel as of September 2026. Each case is underwritten individually.

What LTV and deposit do land lenders want in 2026?

Land lenders typically want a deposit of 20% to 50%, which means a maximum loan to value of 50% to 80%. Where you sit in that range depends mainly on planning. A self-build lender funding your own home on a consented plot sits at the top end. A bridging lender buying bare land with no consent sits at the bottom, and may also want a charge over another property you own. The published criteria below show the spread. These are figures lenders state on their own sites or have given to Knox, with the month we checked them.

Criteria change without notice. Treat the table as a map of who does what, not a quote. Knox checks current criteria on every case before recommending a lender.

Why does planning permission change what you can borrow?

Planning permission changes what you can borrow because it changes what the land is worth and how easily a lender could sell it. This is called planning uplift. A field valued as grazing is worth a fraction of the same field with consent for a house, because a builder or self-builder will pay for the right to build. Lenders lend against value and saleability, so consent lifts both the valuation and the percentage they will advance against it.

An illustrative example: a one-acre paddock on the edge of a village might be valued at £20,000 as amenity land. With outline consent for one detached house, a local valuer might put the same plot at £150,000. With detailed consent and services at the boundary, it might be £175,000. Plot values vary hugely by region, so these numbers are for illustration only.

That uplift works for you in two ways. First, buying with consent already granted unlocks self-build lending at up to 80% rather than 50% bridging. Second, if you buy without consent and then obtain it, the higher value can be refinanced onto a self-build mortgage, and the uplift can form some or all of your equity for the build. The risk runs the other way too: if planning is refused, you own a field worth what a farmer or neighbour will pay, and the lender knows that.

Can I use land I already own as the deposit for a self-build?

Yes. If you already own a plot with planning, most self-build lenders treat its value as your equity, so you may need little or no cash deposit to start building. Ecology Building Society states that if you own the land mortgage-free, it can lend based on the value of the land to start the build. This is one of the most searched self-build questions on Knox’s own site, and it is the strongest position a self-builder can be in.

How it works: the lender values the plot with its planning consent. That value sits in the deal as your contribution. The lender then releases funds in stages as the build progresses, up to its maximum LTV of the value at each stage. If the plot is worth £150,000 and the finished house will be worth £550,000, you start with roughly 27% equity before a brick is laid.

Three things to check. The land must be in your name, or the lender needs everyone on the title on the mortgage. Any existing loan on the land has to be repaid or brought into the new mortgage. And the planning consent must be live, because consents typically lapse if work has not started within three years. Our self-build mortgage guide covers stage payments in full.

Can I get a self-build mortgage that includes the land?

Yes, a self-build mortgage can include the land purchase, provided the plot has planning permission and you intend to live in the finished home. The first drawdown pays for the plot, then the remaining stages fund the build. Ecology, for example, lends up to 80% of the plot purchase price at the start, then releases further funds as the value of the property rises. Other building societies offer similar products, and some lenders prefer to fund the build only, so it pays to know which is which before you make an offer.

The usual cash requirement is a deposit of 20% to 25% of the plot price, plus enough to cover any gap between what each stage costs and what the lender releases. Ecology states that borrowers typically need a 20% minimum deposit to buy the land and a further 15% to 20% of build costs to start the build. Advance stage products reduce that cash burden by releasing funds before each stage rather than after. Your income must support the full completed loan, not just the land element, because the lender underwrites the whole project on day one.

Is a loan to buy land regulated by the FCA?

A loan to buy land is regulated if at least 40% of the land will be used as, or in connection with, a home for you or a close family member, and the loan is secured by a first charge. So a self-build plot for your own house is regulated, and so is a bridging loan to buy that plot. A plot you buy to develop and sell, farmland for a business, or land bought by a limited company is usually unregulated.

This matters for three reasons. Regulated loans carry consumer protections, including affordability checks and the Financial Ombudsman. Fewer bridging lenders offer regulated products, which narrows the panel. And some lenders will only lend on land to a limited company, which pushes a personal self-builder towards the building societies or a regulated bridging loan. Getting the classification right at the start avoids a declined case three weeks in.

How much stamp duty do you pay on land?

Bare land is usually taxed at non-residential rates, which are lower than residential rates and never attract the 5% higher rates surcharge for additional homes. In England, HMRC treats land that is not part of a dwelling’s garden or grounds as non-residential, including agricultural land used for agricultural purposes. Scotland and Wales have their own taxes and bands.

Sources: gov.uk, Revenue Scotland and Welsh Government, checked September 2026.

Worked example on a £300,000 plot. England: 0% on the first £150,000, 2% on the next £100,000 (£2,000), 5% on the final £50,000 (£2,500). Total SDLT £4,500. Scotland: 1% on £100,000 (£1,000) plus 5% on £50,000 (£2,500), total LBTT £3,500. Wales: 1% on £25,000 (£250) plus 5% on £50,000 (£2,500), total LTT £2,750.

Two traps. Land sold with a house as its garden or grounds is taxed at residential rates with the house. And the tax treatment is fixed by what the land is at completion, so if construction of a dwelling has already started on the plot, it may be treated as residential. Get your conveyancer to confirm before exchange.

Worked example: buying a £180,000 plot and building a home

Here is how the numbers work on a typical self-build plot in England, with detailed planning for one detached house. The figures are illustrative, but the arithmetic is exactly how a lender and HMRC would run it.

Compare the bridging route on the same plot. At 50% LTV, the loan is £90,000, so your deposit is £90,000, not £36,000. Interest at an illustrative 0.85% a month for 9 months is £90,000 x 0.0085 x 9 = £6,885, plus a 2% arrangement fee of £1,800, before you refinance onto a self-build mortgage anyway. On a consented plot you plan to live on, going straight to a self-build lender saves £54,000 of upfront cash and roughly £8,700 in bridging costs. Bridging earns its place when the plot has no consent yet, when you are buying at auction against a deadline, or when you are a developer. Model your own numbers with our bridging loan calculator.

When does a land bridging loan make sense?

A land bridging loan makes sense when you need to buy quickly or before the land qualifies for long-term finance. The common cases are buying without planning while you apply for it, buying at auction where completion is due in 28 days, securing a plot before your house sale completes, and developers buying a site ahead of arranging build finance.

Expect to borrow around 50% of value on land with planning, sometimes up to 70% to 75% with full consent and a strong exit, and less or nothing on land without it. Monthly rates on land typically run from around 0.85% to 1.25%, higher than residential bridging because land is a weaker security. Velocity, for example, prices land from 1% a month. Most lenders add a 2% arrangement fee, a valuation and legal fees. Business purpose land deals are often done through a commercial bridging loan.

The lender’s first question is the exit. How will you repay in 12 months: a self-build mortgage once planning lands, development finance, a sale, or refinancing the land onto a commercial mortgage? A vague exit is the most common reason land bridges fail. Buying at auction? Read our auction finance guide first, because land lots are often sold with no planning and a 10% deposit due on the day.

Why do land mortgage applications get declined, and what is the fix?

Land cases get declined for predictable reasons, and nearly all of them can be fixed by choosing the right product and preparing before you apply.

An anonymised Knox land case

This is an illustrative case based on the type of land enquiry Knox handles. A couple in the North West found a 0.4 acre plot with outline planning for one house, priced at £140,000. Their high street bank declined because the land had no dwelling on it. Their own home was worth £420,000 with £160,000 left on the mortgage.

Outline consent alone ruled out an immediate self-build release, and a land bridge at 50% would have needed £70,000 cash they did not want to tie up. The route was a regulated bridge secured on the plot plus a second charge on their home, covering the purchase and the detailed planning application. When detailed consent came through 7 months later, the plot was revalued at £175,000 and the bridge was refinanced onto a self-build mortgage, with the uplifted plot value forming most of their equity. The cash they put in over the whole project was far lower than a straight 50% land bridge would have needed.

What should you prepare before applying for a mortgage on land?

Before applying, have the planning, the land and the numbers in order, because land lenders underwrite the site as much as the borrower. Prepare:

• The planning decision notice, approved drawings and any conditions, plus the date the consent expires.
• The title plan, confirmation of legal access from a public road and any rights of way or easements.
• Evidence of services: water, drainage, electricity, and any connection quotes.
• A build cost plan or fixed-price quote with contingency, and your chosen build route (main contractor, package house or self-managed).
• Proof of deposit and where it comes from, plus 3 months’ bank statements.
• Income evidence: payslips and P60 if employed, 2 years of accounts or SA302s if self-employed.
• Your exit strategy in writing if the first loan is a bridge.

Frequently asked questions

Can you get a mortgage on land?

Yes. You cannot use a standard residential mortgage, but self-build mortgages, land bridging loans, development finance and agricultural mortgages all lend against land. The product depends on planning status and what the land is for. Expect 50% to 80% loan to value.

How much deposit do I need to buy land?

Typically 20% to 50%. A building plot with detailed planning bought for your own self-build can need as little as 20% (Ecology lends up to 80% of the plot price). Land without planning usually needs 50% or more, and some lenders also want extra security.

Can I get a mortgage on land without planning permission?

Sometimes, but only from specialist bridging and commercial lenders, usually at around 50% LTV or less. Together lends up to 50% on land with or without planning, and TFG Capital lends on both. Many bridgers, including Velocity, will not lend on land without planning.

Can I use my land as a deposit for a self-build mortgage?

Yes. If you own a plot with planning, its value counts as your equity. Ecology states it can lend on the value of land you own mortgage-free to start the build, so you may need little or no cash deposit. Any existing loan on the land must be cleared or refinanced.

Do you pay stamp duty on land?

Yes, above the threshold. Bare land in England is usually charged at non-residential SDLT rates: 0% to £150,000, 2% to £250,000 and 5% above. On a £300,000 plot that is £4,500. The 5% surcharge for additional homes does not apply to non-residential land.

Can I buy a piece of land and live on it in the UK?

Only with planning permission for a dwelling. Living on land in a caravan or cabin without consent is a planning breach, and councils can enforce. To finance and build a home, you need detailed planning for a house, then a self-build mortgage to fund the plot and the build.

Is a mortgage on agricultural land different?

Yes. Agricultural mortgages come from bank farming teams, run over long terms and are underwritten on the farming business. Barclays, for example, lends from £25,001 to buy land with fixed rates from 1 to 10 years. They are not designed for someone buying a field as a hobby.

How long does it take to get a mortgage on land?

A land bridging loan can complete in 2 to 4 weeks with a clean title and valuation. A self-build mortgage including the land usually takes 6 to 10 weeks, because the lender reviews planning, build costs and your income. Title or access problems are the usual cause of delay.
