LTT relief when a property trader buys a new-build buyer’s old home
LTT relief when a property trader buys a new-build buyer’s old home
A property trader may not have to pay Land Transaction Tax (LTT) when it buys your old home to help you move into a new build. This is not the usual stamp duty rule. It is instead a narrow relief, with every condition being important.
What this rule is about
Some house moves require a trader to buy the existing home. They need not await an open-market sale.
The relief is intended to cover purchases made in that trade. It is not a general LTT break for anyone buying a home to sell on.
Ask a simple question: is this truly part of a business that buys old homes from people moving into qualifying new homes?
What the official source says
WRA guidance explains that relief may apply where a property trader buys the old home from an individual who buys a new home from a housebuilder. Conditions are set by the legislation. Every one of them needs to be met.
- The buyer must be a qualifying property trader, or a company connected with one.
- The purchase must be part of a business that includes buying homes from people who buy new homes from housebuilders.
- The seller must buy a new home from a housebuilder.
- The old home must have been the seller’s only or main home at some point in the two years before the trader bought it.
- The seller must intend the new home to be their only or main home.
- The trader must not plan to spend more than the permitted amount on value-adding refurbishment.
- The trader must not plan to grant a lease or licence, apart from the limited exception below.
- The trader must not allow its principals, employees, or connected people to live in the old home.
- The land bought must not exceed the permitted area.
Not every buyer counts as a property trader. The definition is limited to certain companies, LLPs and corporate partnerships that carry on a business of buying and selling homes.
For the new home, it must be newly built, or newly adapted for use as one home, and not previously occupied in the relevant way. A connected company can be treated as the trader.
What this means in practice
When every condition is met, the trader’s purchase is relieved from LTT. This relief is not claimed by the seller. It belongs to the trader buying the old home.
There is a trap here: relief can disappear later. A plan may look compliant on completion, but later actions can withdraw the relief.
- Do not assume a short-term letting plan is harmless.
- A lease or licence is allowed only if it is to the person buying the new home and lasts no more than six months.
- Do not let a director, employee, or a connected person occupy the home.
- Keep refurbishment plans and spending under review.
- If extra land is involved, consider whether only partial relief is available.
If the land is too large, relief is not necessarily lost altogether. Only part of the price is taxable. The law uses the market value of the permitted area.
How to analyse it
Go through the facts in order. A promise in a sales brochure will not settle the answer on its own. What matters is the documentation and the real plan.
- Confirm that the buyer fits the statutory definition of a property trader.
- Check that its business includes this type of purchase.
- Check who built and sold the new home.
- Establish when, and how, the seller used the old home.
- Record the seller’s intention for the new home.
- Calculate the permitted refurbishment amount before approving works.
- Check intended occupation and any letting arrangements.
- Measure the land and consider whether it is permitted area.
- Monitor what happens after completion.
For refurbishment, the permitted amount is the greater of £10,000 and 5% of the price paid. However, it can never exceed £20,000. Cleaning and work needed only to meet minimum safety standards are not refurbishment for this rule.
Example
Rhodri’s company buys Ceri’s old home for £300,000. Ceri buys an unoccupied new home from a housebuilder and plans to live there. She lived in her old home during the previous two years. Five per cent of £300,000 is £15,000, so that is the permitted refurbishment amount. Relief may apply if the company meets the other conditions and plans £15,000 or less of value-adding work.
Now change one fact. If the company later spends £22,000 on refurbishment, the relief is withdrawn. It must then make a further return to WRA.
Why this can be difficult in practice
This rule is fact-sensitive. Although the wording “only or main home” looks familiar, the evidence still matters. So does the buyer’s real business model.
Another problem can arise from land. Half a hectare is normally within the permitted area, but a larger area may qualify where the home’s size and character mean it is needed for reasonable enjoyment.
- The source page refers to a six-month lease or licence. The statutory exception is narrower: it must be granted to the person buying the new home.
- Calling work “repairs” does not decide whether it enhances value.
- Future plans can matter, not just work already completed.
- Extra fields, paddocks or gardens may need valuation evidence.
- A later breach can create an LTT bill even where the original claim was valid.
Following a disqualifying event, the trader must send WRA a further return with a self-assessment within 30 days, starting on the day after that event. Tax due is the amount that would have been due without the relief.
Key takeaways
- This LTT relief is for a specific new-build moving arrangement, not ordinary property trading.
- All of the conditions must be met when the trader buys the old home.
- Later refurbishment, letting or occupation can withdraw the relief.

Official guidance
The pages below are the Welsh Revenue Authority’s guidance. Guidance is not law. It sets out how the Welsh Revenue Authority reads the legislation, and it is not binding on you, on a tribunal or on a court. Where guidance and the legislation differ, the legislation wins. the Welsh Revenue Authority can also change or withdraw guidance, and it may not cover your facts.
Where this is not settled
- Whether land above 0.5 hectare is needed for the reasonable enjoyment of a home depends on its size and character.
- Whether proposed work enhances value, rather than being cleaning or necessary safety work, can depend on the facts.
- The material supplied does not state the currency date of the bundled legislation. Current law should be checked before relying on it for a later transaction.
Evidence you would need
This kind of case is decided on the facts of the individual property. These are the records that usually settle it, and the ones an adviser would ask you for.
- Documents showing the seller bought a qualifying new home from a housebuilder.
- Evidence that the former home was the seller’s only or main home during the two years before the trader bought it.
- Evidence of the seller’s intention to live in the new home as their only or main home.
- The trader’s business records and company structure.
- Budgets, invoices and records for any work to the former home.
- Details of any occupation, lease or licence after the purchase.
- Plans, title documents and valuations where the land may exceed the permitted area.
