Indemnified Letter of Advice
Conveyancer holding things up until they have written SDLT advice? I'll provide a formal, insured opinion so they can proceed.
If your SDLT position isn't straightforward, a letter of advice is your evidence of reasonable care — the legal reasoning, documented and defensible, if HMRC ever ask questions.

Nick Garner
How it works
Three steps. You only pay if a formal letter is needed.
You email me your case details
No forms, no phone tag. Just send me the facts — purchase price, property details, what's happened so far.
I clarify your position — free of charge
Based on the evidence you give me, I'll set out the legal position as clearly as I can by email. This costs you nothing.
If a formal letter is needed, we go from there
Sometimes the email is enough. If your conveyancer needs something indemnified and on file, I'll quote you a fixed fee before work begins.
Start with step 1. There's no commitment and no cost — just email me the details and I'll tell you where you stand.

Why a letter of advice is worth having
If your solicitor or conveyancer is uncomfortable determining the SDLT position themselves, that is a strong signal. It means the treatment is not straightforward — and if it is not straightforward for a qualified professional, it is exactly the type of transaction HMRC are more likely to enquire into.
This risk increases with the size of the transaction. Higher purchase prices mean larger SDLT liabilities, and larger liabilities attract more scrutiny. If there is any question about whether the higher rate applies — and you are a taxpayer who wants to reduce your liability safely and lawfully — then obtaining professional advice is the practical step to take.
A letter of advice serves two purposes. First, it gives your conveyancer a formal, insured opinion they can rely on and keep on file, so they are comfortable filing the return. Second, if HMRC do open an enquiry, the letter acts as a first line of defence: it sets out the legal reasoning, the evidence, and the basis for the position taken.
Elevated enquiry risk
If the SDLT position is difficult enough that your solicitor will not handle it directly, HMRC are more likely to query it — particularly on higher-value transactions where the tax at stake is substantial.
First line of defence
The letter provides a documented, reasoned opinion that can be presented to HMRC in the event of an enquiry. It shows the position was considered, evidenced, and professionally advised — not guessed at.
Penalty protection
If HMRC determine the self-assessment was incorrect, having taken professional advice significantly reduces the likelihood of penalties. It demonstrates reasonable care, which is the key test HMRC apply when considering whether a penalty is due.
The practical position: I can clarify your SDLT position free of charge. If a formal letter is then needed — either because your conveyancer requires one, or because the enquiry risk warrants it — you have a fixed-fee, insured opinion from £350 (no VAT) that protects both you and your conveyancer.

Trusted by buyers and conveyancers who needed clear, written land tax advice
It is so refreshing to see that there are still people out there providing a highly professional pro-bono service! I cannot recommend this enough!
Thanks you Nick.
Once again, thank you, Nick.
We couldn't believe how quickly he responded to us and it explained the matter with such clarity and detail which helped us understand our position and greatly reduced our stressed! We can't thank Nick enough!
With such a specific case, I couldn't find any advice online and Nick's response gave me the confidence to proceed with our plans AND the practicalities of what documents I would need to show HMRC that my situation actually makes me a first-time buyer. Super clear and professional.
Highly recommend and when we buy, I'll definitely use Nick's services for an indemnified letter. His free advice is genuinely valuable and NOT a way to get you to pay money for answers or to milk fees from you.
Thanks Nick!
Professional, knowledgeable and considerate - highly recommended!
Their professionalism, knowledge of the process, and ability to act efficiently made what could have been a stressful experience feel completely manageable. It’s rare to find someone so responsive and effective — I wouldn’t hesitate to recommend their services to anyone dealing with property-related matters.
Nicks professional knowledge and expertise outlined clauses of stamp duty where I was not required to pay stamp duty for stair-casing and based upon remaining percentage being purchased.
This evidence was used to relay back to my solicitor who acknowledged there would be no further action required to pay stamp duty.
This saved me a few thousand pounds.
Nick is highly professional, reliable, takes interest into each clients needs. Would highly recommend and will use in the future.
I have been trying to make sense of the legislation for some weeks now and Nick unravelled the knots that i've mentally made of our complicated situation.
He patiently listened whilst I described the multiple aspects and then explained the related schedule to each element in such an easily understandable way, happily clarifying any aspect that I was unsure of.
Nick then invited me to e mail him so that he could explain in writing and refer to the relevant legislation schedule.
I recieved his reply so quickly and the information was presented stage by stage with such clarity that I now feel completely confident that I know which tax is due (and which isn't !!)
I can't thank or recommend Nick enough for his remarkable service.
It's a huge weight lifted !! and i'm ever so grateful.
I struggled to find the answer myself from reading the legislation and tax advisors quoted 100s of pounds in order to research and tell me if the correct answer was yes or no.
Nick responded quickly, same day and provided the answer with a detailed explanation. Exactly what I needed to comply with the legislation. Thank you so much for your help.
Nick thoroughly went through my case in detail, provided with a clear answer and also attached the legislation supporting the answer he provided.
I would definitely recommend their service. Thanks.
Take Julie
He explained everything in an easy-to-understand way, also providing with reference to the guidance, ensuring we felt confident about the process. His professionalism, knowledge, and approachable manner made the experience seamless and stress-free.
We left feeling much more confident thanks to his help!
Highly recommend!

Email your question — I will clarify the law
I will respond to your question free of charge. If your conveyancer then needs a formal, insured opinion on file, a letter of advice is available from £350. No VAT. A quote is always provided first.
What to include in your email
The property address, price, expected completion date, who is buying (names, relationship), what other property interests you have (including shares, trusts and overseas property), and why you think the position is non-standard. Attach any documents you already have — title plan, contract pack, listings, trust deed, separation agreement, planning documents.
If your conveyancer has already flagged "we need insured SDLT advice", email early. Late-stage letters can delay exchange or completion because evidence needs to be checked properly.
If you found this helpful, please support the service by leaving a Google review or making a small donation to Mind, Dogs Trust, or the Trussell Trust.
For matters requiring a tax agent to submit the return, I offer access to Compass SDLT.
