Fees and Feedback
Details regarding our approach to fees can be found at the following link: http://www.clerksroom.com/content-html?cid=514
Please see “profile” tab for a description of the legal services provided by this barrister.
We aim to complete and return all paperwork within 14 days (2 weeks) of receipt if no specific deadline is provided. We can work to much faster timescales if requested or we can agree a specific target date for each individual circumstance. We will always advise at the outset if counsel is unable to meet any deadline.
Each barrister has a standard hourly rate for their work. The individual hourly rate can be agreed when instructions are acknowledged if preferred. We welcome early discussion as to the suitability of a specific barrister for a specific case. The right barrister will have the relevant expertise to deal with the case but will not be too junior, or too senior depending on the complexities.
We aim to allocate all cases to the correct level of experience & seniority which we believe will prove most to be the most cost-effective solution for our clients.
If, due to urgency, we allocate paperwork to a more senior member of Clerksroom, we will charge the appropriate hourly rate for the work, not for the barrister. We welcome early discussion to ensure the correct fee is applied to the case at the outset.
All our barristers are regulated by the Bar Standards Board (BSB) and hold a current practising certificate, details can be found at the following link Barristers’ Register

1. This is a privacy notice that describes how, why and for how long I will process or keep your personal data in accordance with the General Data Protection Regulation (‘GDPR’).
2. The GDPR governs how an individual’s personal data is used, and your rights in relation to that data.
3. I, Henry Mainwaring, have been instructed by you or your litigation friend (usually a parent), through your solicitor or agent, or via the Bar Pro Bono Unit.
4. It is necessary for me to process your personal data in order for me to provide you with legal services, for example:
· Advise on the prospects of litigation;
· Advise on the value of your claim;
· Representation at a court hearing;

7. If you have instructed me on a direct access basis, or engaged a solicitor (or legal agent), to assist you in bringing or defending a claim then the processing is necessary to perform a contract to which you are a party (Article 6(1)(b) GDPR). To give effect to that contract (i.e. to bring a claim) it is necessary for me to process your personal data for litigation purposes.
8. If I am assisting you on a pro bono basis, it will be necessary for me to seek your consent to be able to represent you (Article 6(1)(a) GDPR). In this scenario, you will be sent a consent form.

For example, personal data that reveals your race, ethnicity, sexual preferences, political or religious beliefs, trade union membership or health. There are also restrictions for processing information regarding criminal convictions.
11. This type of personal data will only be processed where it is necessary in order to represent you in your legal claim, or advise on the prospects of a legal claim.
12. I will retain your personal data for no longer than is necessary, and where it is possible, I will anonymise your data.
13. How long your personal data is kept will depend on a number of factors. The retention period will be reviewed when the service I am providing you with is complete.

14. Once your case has concluded and fees have been paid, I shall retain only the personal data necessary for the following purposes:
(i) The legal and professional obligation to retain information relating to my cases;
(ii) To check for any potential conflict of interests that may arise in the future when I am instructed on other cases;
(iii) For use in the defence of potential complaints, legal proceedings or fee disputes;

15. The processing for the purposes listed in paragraph 14 (ii), (iii), and (iv) above, will take place in accordance with Article 6(1)(f) GDPR. That is, for the purposes of legitimate interests that are not outweighed by your interests or fundamental rights and freedoms.
16. The processing for the purposes listed in paragraph 14(i) above, will take place in accordance with Article 6(1)(c) GDPR. That is, the processing is necessary for me to comply with a legal obligation.
17. Where processing of your personal data was based on your consent (see paragraphs 6 and 8) you have the right to withdraw that consent at any time. This does not affect the lawfulness of the processing based on consent before its withdrawal.
18. Withdrawal of your consent to process such data will most likely mean that I am no longer able to provide you with the legal services you seek.
19. You may request confirmation that your personal data is being processed by me and details about the personal data, the source, the processing, the purposes of the processing, the recipients and the retention period.
20. You may request a copy of your personal data that is being processed by me. You may also request rectification (i.e. correction) where there are inaccuracies in the personal data.
21. You have the right to object, on grounds relating to your particular situation, at any time, to processing of your personal data in paragraph 14 of this privacy notice. Should you object, the processing will only continue where there are compelling legitimate grounds for the processing which override your fundamental rights, freedoms and interests.
22. Where the processing or retention of your data is necessary for the establishment, exercise or defence of legal claims, it will not be possible to object.
23. You have the right to request that your personal data is erased where any of the following apply:
(i) The personal data are no longer necessary in relation to the purposes for which they were collected or otherwise processed;

25. Where it is necessary to correct your personal data, or you have requested the restriction or erasure of your personal data, I shall endeavour to contact the recipients of the personal data, unless this involves disproportionate effort.

C. Parry Lay Client
Special thanks to Henry Mainwaring. The hour I spent with him before the trial was very productive and I was impressed by the amount of time and effort that he had put into my case and the successful outcome of the trial.
Julia Smedley Spencers Solicitors
Thanks [Henry Mainwaring] for all your efforts and the excellent result!
Nigel Steffens, CEO Fespa Limited
...Henry Mainwaring did an excellent job...we won with costs. He was extremely professional throughout and had obviously done his homework prior to the trial. I would have no hesitation in recommending him for any future case.
Jeffrey Palmer Croftons LLP
We were extremely pleased with the work Mr [Henry] Mainwaring undertook in this case. A telephone conference I had with Counsel immediately prior to the hearing demonstrated Counsel had prepared the case in great detail. Counsel achieved a great result and I was particularly impressed with Counsel's overall conduct of this case. His views were very much endorsed when the papers were returned and I could not fail to notice that the trial bundle had been meticulously tabbed and cross-referenced. To me, as a senior member of a firm of Solicitors, it demonstrated the amount of work Counsel had spent in preparing for the trial in this case.
Joanne Barber Carpenters
Counsel [Henry Mainwaring] went the "extra mile" that the case required to achieve a very pleasing outcome and we are extremely grateful for Counsel's assistance in this matter [RTA case] given the challenging nature of the brief and case itself. We would certainly be more than happy to instruct Mr Mainwaring again and wished to provide some positive feedback regarding the hard work and the successful result today as we felt that this was truly well deserved.
