Nick was fantastic to work with. I had a complicated SDLT question and he took the time to properly understand the details before giving his view. His explanations were clear, thorough, and easy to follow even on quite technical points. Would highly recommend for anyone needing land tax advice on a non-standard situation.

★★★★★ Nick was incredibly helpful in advising me on a complicated and time-sensitive SDLT issue. His responses were exceptionally prompt, clear and thorough, and he took the time to understand my individual circumstances before giving me a clear answer. I particularly appreciated that he looked at all the possible options while being completely upfront about what was and wasn’t sensible in my situation. He even advised me not to incur the cost of formal advice unless my solicitor actually required it. Professional, knowledgeable, generous with his time and genuinely helpful. I wouldn’t hesitate to recommend Nick.

I’m very grateful for Nick’s professional and detailed advice regarding our SDLT situation. Our circumstances were quite specific and involved a previous main residence overseas and a separate rental property, so we wanted to make sure the SDLT treatment was correct. Nick took the time to carefully review the facts, explain the relevant points clearly, and provide a thorough and professional assessment. His advice gave us much more confidence about our property purchase and our SDLT position. He was also very responsive, helpful and reassuring throughout the process. I would highly recommend Nick to anyone who needs professional SDLT advice. Excellent service and very much appreciated!

Nick was so fast at responding to my query. He was very polite and very informative. Although the outcome was not what we had hoped for, the advice that Nick provided was invaluable. Nick provided advice that 5 other professionals could not. I am very grateful for his help and the clarity that he gave me. Would 100% recommend. Thank you again!

This is the best service I have ever used in the UK. Nick and his team were professional, friendly, responsive, and worked on a no win, no fee basis, with very reasonable fees. I contacted more than 10 tax advisers that I found on Google, and Nick was the first to respond. His reply was prompt, highly professional, and answered exactly what I was looking for. They submitted our SDLT refund claim on 4 June 2026, and we received the repayment on 10 July 2026. The whole process was smooth, efficient, and completely hassle-free. I would highly recommend Nick and his team to anyone looking for tax advice or help with an SDLT refund. Excellent service from start to finish. Well done!

I contacted Nick for guidance on a complex SDLT issue involving the transfer of a residential property to a limited company and the related implications for a new home purchase. The response I received was exceptionally detailed, clear and practical. The advice carefully explained the relevant SDLT principles, including connected-party transfers, market-value requirements, valuation evidence, the potential corporate rate and the importance of timing between transactions. What I particularly appreciated was the balanced and careful way the information was presented. It helped me understand the key risks and the practical next steps to discuss with my solicitor. The guidance was extremely useful, clearly written and provided with real care and professionalism. I am especially grateful that such a thorough initial assessment was provided free of charge. I would highly recommend their services to anyone needing specialist SDLT advice.

Nick provided an exceptionally detailed and thoughtful assessment of a very technical SDLT issue relating to property trader relief. His explanation was clear, balanced and extremely helpful, particularly around the distinction between refurbishment, repair works and minimum safety works. What I appreciated most was the level of care and nuance in the analysis rather than giving a simplistic answer, he carefully explained both the opportunities and the risks, as well as the practical evidential considerations involved. The response was comprehensive, commercially aware and easy to understand despite the complexity of the legislation. I would highly recommend Nick to anyone dealing with complex SDLT matters or property tax issues.

I contacted Nick regarding a particularly complex SDLT issue involving overseas property ownership and higher rate SDLT implications. Unlike many other professionals I approached, who either ignored my enquiry or refused to provide any meaningful guidance because of the international aspects involved, Nick took the time to reply in detail and explain the position very clearly and professionally. His response was thorough, balanced and extremely helpful in understanding the relevant legal and practical issues before proceeding with a property purchase in London.

We were really struggling to find clear advice regarding Stamp Duty and were so relieved to come across Nick. His advice was professional, thorough, and explained in simple layman’s terms that made everything much easier to understand. What really stood out was that several solicitors we approached were either unwilling to give proper advice or would only provide rough figures for how much Stamp Duty we might have to pay, without fully exploring the legislation or our circumstances. Nick took the time to carefully look into the details and explain everything clearly and confidently. We are extremely grateful for his help and would highly recommend him to anyone needing reliable and knowledgeable Stamp Duty advice. 5 out of 5 stars from us both.

We are extremely grateful to Nick Garner for his outstanding help and professionalism. After other companies were unable to assist us or recover what we were entitled to, Nick handled everything with confidence, knowledge, and great attention to detail — and successfully secured the return we deserved. Despite being based in the UK while we are in Sweden, the entire process was impressively smooth. Within just a few emails, everything was clearly explained and efficiently resolved. Nick is highly professional, reliable, and truly dedicated to achieving the best outcome for his clients. We couldn’t recommend him more highly. SHADI J

I would like to thank Nick for the prompt and thorough responce he gave to my query. I must admit I was quite sceptical and at first I thought that the free email advise offered on the web site might well just be some sort of a bait to get you go with the paid service. I was so pleasantly surprised when I recieved a most prompt and exhaustive responce to my question. 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.

Outstanding. It's easy to be slightly dubious about contacting any expert online for advice and I had a reasonably complex Stamp Duty refund question but not only did Nick come back to me within 24 hours but he also provided with the information that fully answered my query without necessarily leading me into further communication. Highly recommended for both his customer care and for his expertise.

I am extremely impressed with the knowledge and level of service Nick provided—I truly can’t thank him enough for the excellent job he did. Nick advised me on SDLT where a limited company was purchasing a probate property, an area where most solicitors were unable to help. His expertise made a real difference. Thank you again.

Nick Garner is outstanding. I contacted him with a complex SDLT question relating to a trustee purchase under a life-interest trust, and he responded quickly with a clear, structured explanation supported by the relevant legislation. He set out the correct SDLT treatment and provided a precise calculation that removed all ambiguity for my conveyancer. Calm, highly knowledgeable and incredibly helpful. If you need SDLT advice from someone who truly understands the detail, Nick is the person to speak to.

Nick has been fantastically helpful. We are buying our neighbour's garage & driveway, but we simply could find no definitive answers as to whether SDLT was payable on our purchase. Nick analysed our circumstances, provided written reasonings, then provided his conclusion. We cannot recommend Nick highly enough!

Florin Gheorghiu

Nick's prompt and clear response was invaluable – I was dealing with quite a specific edge case where I am the legal owner of a property abroad, but do not have any major interest in it, as my parents rent it out and make use of the money. The question was whether I would qualify for the SDLT first-time buy relief and whether the higher rates for SDLT apply to me. 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!

Debbie Stone

Nick helped us with a very detailed answer in support of our son Ollie's (first time buyer) 'equity share' house purchase, for which his solicitor had mis-calculated a higher rate of SDLT (on the market value rather than the purchase price). We were desperate for a detailed enough proof of calculation to satisfy the legal team and Nick's help has saved us. Our son could not have afforded the higher rate they had miscalculated. His work is invaluable as are the causes he supports

Luke Thomas

Nick was a massive help with Stamp Duty issues surrounding stair casing on my flat. My solicitor was certain the remaining percentage purchase of my flat resulted in me paying Stamp Duty of a few thousand pounds. 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'm absolutely delighted to have found this website and to have been able to speak with Nick !! 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.

My solicitor was unable to provide advice with certainty about a specific transaction involving LBTT, a yes or no question. 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 is very knowledgeable regarding this field. Not only is he knowledgeable he make it very easy to understand the minefield of stamp duty. Nick has just saved me over £7,000 in stamp duty as its not payable on my planned move. It's easy for a solicitor to say you owe X amount in stamp duty its not their hard earned money being paid out unnecessary. I will never be able to thank Nick enough. My advice is if you think your solicitor has got it wrong seek out Nick. Once again Nick thank-you so much. Take Julie

I was stressed out today believing we needed to pay stamp duty on a transfer of a house when previously I didn’t think we did. I called up and asked for advice, explained my situation and that I did not understand. It was explained really clearly to me, which was so helpful. I had already tried to get advice from my accountant who did not know the answer. In fact no one seemed to know the answer until I made this phone call so I am relieved I did.

My wife and I newly moved to the UK and encountered a problem over the eligibility of first time buyer. I contacted Nick over the phone for enquiry. Although I made the enquiry without any payment to Nick, he seriously took my case and eventually gave me very useful information, which greatly helped us to make decisions for the declaration of Stamp Duty. Throughout our communication, we definitely saw and felt Nick's passion and expertise in land tax field and professional comprehension of the law as well as very high efficiency. Seeing the information and explanation of the law given by Nick, we were certain that our simple question did cost Nick quite a bit time and efforts, yet he was all the time very polite. Seeing his true willingness and passion to help, patience, efficiency and expertise in land tax and the law, we truly admire this sage gentleman. Thank you very much Nick for helping us.
