“I have had help with my computer before but David was the first to get to grips with my myriad problems while simultaneously explaining what he was doing and giving invaluable advice. Three hours went by in a flash leaving me in a better world altogether as far as my PC is concerned.

Dear David,

I have been happily emailing out and receiving in to the outlook set up enabling me to delete out duplicates and find all my society mail in the one place. It is wonderful and I am very grateful to you for sorting it.
I am a little computer savvy and seeing the stages and checks you made I am thinking that I could have done it given fifty uninterrupted years to sit and think and work through the out of date help notes and things so two hours of your time and help – golden.
If I have more things I want to set up I will not hesitate to call on you.

Best wishes,


David, Lausanne, Switzerland

“I was in the UK on a business trip and my laptop caught a very nasty virus. David came to my hotel and within a short period of time got everything cleared up and I was able to work again. I can’t explain how grateful I am for his help. David, once again, many, many thanks!”

Donna, South London

David was fantastic with the help and support his company offers. The session was tailored exactly to my requirements and I was able to use my work laptop to learn further IT functions.
Of all the IT consultants I contacted; not only was the price David offered very competitive, most companies did not offer the bespoke course that I was looking for, but David did.
He was able to come to my location of choice which made it a lot easier to plan my time effectively.
I would definitely recommend his services and would absolutely call on him again if need be.

David, Balham

Many thanks for your careful, sympathetic and thorough approach and action when you came to see me.

My laptop is working much better and at last I have a functioning printer.

Rupert, Clapham

I cannot thank David enough for setting up my new computer. In 2006 I had installed my old Dell Windows XP computer without any help and without any problems. However, on getting my new Dell Windows computer in 2014 I felt uneasy about attempting it again by myself, as everything to do with computers seems to have become more complicated and stressful than it was 8 years ago. I was therefore in need of some friendly, experienced and knowledgeable person who could sort out any potential problem and deal with all the stress I would otherwise have felt myself.

So I was more than a little overjoyed when I came across David’s website, and all of the encouraging testimonials left by many of the people David has helped over the years. As for my computer set-up, I had been right to be wary of doing it by myself as it proved to be more than a little challenging. For example, because my computer had a graphics card the monitor wouldn’t work when first switched on even though the set up was in accordance with the written instructions that came with the equipment. However, David, who understood the problem, knew immediately that I needed to use a different cable not specified in the instructions, a cable that we eventually found lurking at the bottom of the box.

Had I been on my own I would have been entirely defeated. Then there was the problem I had with “Microsoft Office 2013”. It should either have been pre-installed by Dell on the computer or else come in the form of a CD, neither of which proved to be the case. Again, had I been on my own, I would have been entirely defeated as well as totally stressed. So, once more, I cannot recommend David more highly to anyone needing help with their computer, whatever their level of previous experience.

Nicky, Chiswick

Hi David,

Peter was thrilled with the work you did on his computer, and feels very
safe in your computer whizz hands. I will be in touch in the next few months
arranging when he would next like to see you.

Thank you for coming


Tony Morris, Psychotherapist, Putney

I used to be an IBM programmer, then a computer network manager, and latterly taught computing (Word, Excel, etc) before the systems software side became far too complicated for me!

So with that background I can really appreciate David’s knowledge and skills, and I particularly take to his reasonable fees, that he works quickly but doesn’t rush, is friendly and open so will listen to you and your difficulties. He doesn’t blind you with jargon, will explain what he’s doing and why, or just fix it if you prefer. He’s got me out of trouble when the problem was beyond me. I’ve recommended him to many friends and colleagues

Mel, Ilford

John, Mature Student, North East London

Having previously been on the receiving end of a patronising, and impatient, IT consultant and trainer, I found David’s approach very refreshing.

His professional advice, and technical support, was delivered in a non-patronising manner, with great clarity – free from complicated jargon.

Having advised me that I needed a new router, and a more efficient and workable, internet connection, David quickly turned the situation around. His general and impartial advice, on computer software was also most helpful and informative.

David’s expertise has enabled me to resume my academic studies from home. A godsend for all students who prefer to study in familiar surroundings.

Significantly, David deals with his clients problems in an empathetic manner. He fully understands, and appreciates, the difficulties and limitations, of those without his technical knowledge.

Without hesitation, or reservation, I thoroughly recommend him.

Christine, Devon

Dear David
Your blog is always interesting even if sometimes a bit beyond my capabilities! But this latest one was extremely helpful and the snipping tool is a wonderful find – I’ve been trying to work out how to save extracts from websites without having to print out page after page.I’m sure there are so many things on Windows 7 that I simply haven’t discovered and don’t want to spend hours teaching myself everything it can do – so many thanks for these pointers, which are invaluable for us amateurs!
best wishes

Sue, Surbiton

Thanks for all your efforts fixing my computer, even though inadvertently, I nearly sabotaged everything by turning a switch off, (which of course we won’t mention) so without your help I would still be unable to continue my work with a local Resident’s AssociationThanks again

Nicole, Esher

I was very impressed with your teaching. You are one of the few computer experts I have met that can explain things simply to those of us that do our best to resist technology.

Sue, Stockwell

My feedback is all positive as what your consultancy provided me with was just what I needed after a hard disc crash – prompt, very helpful, courteous, non- patronising (you didn’t make me feel stupid for not understanding terms and functions etc – you have no idea how important this is!) and available to provide follow-up assistance plus good value for money.

Stuart Campbell

David, my thanks once again. I will be delighted to be added to your list of very happy clients!

Anne Stephenson (Doctor)

David has been a wonderful support for us and our computers over the years. Recently my daughter’s computer broke down in the middle of A-levels and he came straight over and sorted us out within a couple of hours which was a god-send. He is totally reliable and very intelligent and also an interesting person to sit with over a struggling computer. Thanks David.

Wendy, Wandsworth Common

I am glad that I found you, you were superb.


Thank you so much for your help yesterday. And thank you for the information in the email below. Talk about good after-care!
You are honest, trustworthy and totally professional. It was a pleasure to meet you. I will certainly be recommending you to anyone I know who needs computer help. And equally I will be in touch again if I ever need your help. Thank you again.

Deirdre Gough

Therapist, London, UK

I have known David Leonard for more than five years. Whenever I go completely mad with my computer and can’t make it do what I want, need to upgrade, find out information or just need help, David has always been there for me. Recently I decided to advertise with Google …………. in 25 years of running my own therapy practice I have never advertised and was slightly anxious about trying it. David explained the whole process of how Google could work for me. We set targets, defined markets, set the geographical area where my ads are shown, and chose the ads and keywords we would start with. We also agreed the amount of money I would spend each day. He explained that I can turn the campaign on and off at will. He put me in control while he does the fine tuning each day to maximize the clicks I receive. I believe that online advertising is the way to go, but I needed expert help as I didn’t want to run the campaign myself. It worked…………

Clinical Psychologist & Lecturer (respectively)

David has always been extremely helpful in solving any problems we have encountered. For two professionals working for themselves, dependent on a computer functioning all the time he has been a life line throughout, now for umpteen years. Eg he managed to retrieve all Lilly’s data from a very serious computer crash – an absolutely god-sent rescue! Lilly, who also – for a separate task to her main profession – needs constant, reliable access to the Internet, has frequently been rescued by David with numerous daunting problems encountered in that area. David has last year set up Lilly’s website, a great success, too. He then helped her through the ghastly maze of being accessible on Google – don’t try it yourself, unless you have endless time and patience. He is ‘managing’ her Google stuff – one less thing to think about, at an extremely reasonable fee. He has always been easily accessible, often helping over the phone eg. We never had to wait long for his help, if he had to come out to see us. Lilly is completely dependent on his extremely reliable service, and he has never let her down. David is always pleasant to have around. He explains matters really well ( and patiently!!!). His fees are most reasonable. In short, we cannot recommend him highly enough.

I was delighted to discover David Leonard’s IT consultancy and to have the benefit of his patience and skill in helping me to deal with some of my computer problems. He was particularly persistent with trying to stem the tide of spam recently. I have greatly appreciated the speed of his response, his ethical approach to charging and his ability to use a language that I can understand!

Colin Brennan

As a freelance journalist nothing can come between me and meeting a deadline including IT blips, bugs and viruses. It is not a matter of the ‘show must go on.’ The show will go on with or without me. Since David came on the scene, I have become confident that when problems come up, they will be solved and I can get on with what I am meant to be doing. That is a nice feeling.

David Leonard created a full suite of software for us in 1985 and has made many improvements over the years. We still use much of the software almost continuously. Although it has been reliable and robust, we call David in from time to time from his South London business address to our Oxfordshire offices. He continues to provide first class advice and technical support and has become a trusted friend to us and our business.
