Fiona C, Uxbridge

Dear Miles,


I would just like to thank you for your assistance in getting our locks replaced at work and at home.


On both occasions you quickly identified what the problem was and only carried out necessary work to correct the problem. At home, I had convinced myself that I would need a new lock, but you identified it was just the alignment that was out. Not knowing anything about locks, it is very reassuring to know that I will only be charged for the essential components and repairs that are required to fix the problem.


And on both occasions having completed these two jobs, you left the surrounding area clean and tidy and took the opportunity to explain to me what work you had carried out.


Taking this all on board I will have no hesitation in highly recommending you to others, as a trustworthy and friendly locksmith who will not let the customer down.


Kind Regards


Yours sincerely



Alina P, Hatch End

Dear Miles,


Peter and I were really fed up on having to slam the door every time we came out of the house especially in the early hours of Wednesdays and Fridays when we leave super early, but most importantly our neighbour was constantly complaining about the noise!


We came to you for advice and guidance and you kindly offered to come round to take a look at the problem.


Due to our work commitments, the visit was booked for a Saturday. You were on time and very professional. It turned out that the problem was in fact the lock, which you have replaced, and now our entrance door is a delight to handle! AND no more complaints from our lovely neighbour!!


I would just like to add it was a pleasure doing business with you.


We will definitely keep recommending you to anyone we come across that requires your services.


Many thanks,


Alina & Peter

Phillip B, Apsley

Miles from Essential Locksmiths came round to conduct one of his free home security surveys as requested; he was promptly on time, polite and professional with a smile.


After Miles had completed the survey he pointed out that the ground floor bedroom windows were not very secure and that he recommended I had additional security locks fitted.

Upon his professional advice I agreed for the work to be carried out there and then. When it comes to your family and your personal possessions you can never be too careful!

I would fully recommend Miles from Essential Locksmiths due to his high attention to detail and professionalism whilst working in people's homes. He even wore shoe covers to protect our carpet!!

Lee H, Shenley

To Miles from Essential Locksmiths.


For the first time in my life I left my keys in my flat as I was just going out to visit some friends.


I called you up and within five minutes you were at my flat (much quicker than if I called 999 in an emergency!).


Within a further five minutes you opened my door without needing to charge me for a new lock.


I must say, not only was I impressed with the speed of your arrival, but more importantly your honesty in getting me into my flat without saying I need a new lock.


Miles - thank you very much for everything you did for me and I would have no problem in recommending you to anybody in the future.


I couldn't recommend you highly enough.


Thanks once again.

Paul M, Cheshunt

Dear Miles,


I wanted to drop you a short line to thank you for your time and advice regarding the replacement of locks at my home. Having been burgled in the past I feel I am quite security conscious, however I was not aware of the potential weakness of the locks that were fitted to my UPVC doors until hearing your security presentation.


Following your advice, I could clearly see the benefit of installing more robust, high security locks which would present a far greater challenge to any would-be burglar. The service provided, from measuring up to installation, was hassle free and I appreciate the speed with which you completed the job.


The work was carried out efficiently and with a minimum of fuss at a reasonable cost. I am very happy with the outcome and would not hesitate to recommend your services to others.


Thanks very much.


Yours sincerely,


Paul M

Harvey S, Stanmore

Miles from Essential Locksmiths came over to my home to do an assessment of the patio door locks following on from hearing about lock snapping on the Internet.


He explained fully about the potential problems with the existing locks and how installing new high security locks would improve the situation.


He ordered me five new locks with the added benefit of all operating from the same key.


The work was all done within 3 days of him assessing the job; no mess, no fuss.


I would not hesitate to use Miles again.

Sara P, Totteridge London N20

Thanks so much Miles for coming today to fix all my window locks!!


Not easy, great job thanks !

Joel D, Radlett

Great job and great response! I don’t think we can ask for more…

Mya'Maria N, Croxley Green












Bobby L, Elstree

Miles is a total lifesaver! I needed my locks changed in an emergency - called him at 1700 and at 1730 he was at my house changing the locks. Job Done!


If only every professional could provide a service like this. If you ever need a locksmith look no further!

Gavin D, Andrew Pearce Property Consultants, Pinner

I work for Andrew Pearce Property Consultants in Pinner.


Recently I was recommended to Miles at Essential Locksmiths for any locksmith needs in the future. When I needed Miles I called him two hours before I needed the job to go ahead and he was very accommodating to try and fit me in. He arrived on time and was very professional in every aspect of his work.


I will certainly being using Miles again as I feel he is somebody I can rely on when he is required.

One evening last week, I found myself locked out of an internal door in my house.


I spoke to my nephew, Matt, who was able to refer Miles Hartzel to me. Miles said that he would be with us in North London within 30 minutes to take a look but arrived within 25 despite rush hour traffic.


Miles explained that drilling the lock would be a last resort as he preferred non destructive entry. His assessment of the situation was thorough. In the end he was able to remove and somehow squeeze through a small, high level internal window, thankfully without injuring himself.


Miles is a polite and professional individual whom I would have no hesitation in recommending to any of my friends and family for emergency situations. 

Janie A, Bushey

A brilliant service.


We called, you came. No fuss, no mess.



Shelley D, Finchley London N3

Dear Miles


I want to thank you for your prompt attention to our security and privacy issues.


You provided some very simple solutions to our various requirements and installed them very quickly and neatly.


I was very happy with your excellent service and I will gladly recommend you to anyone who needs a reliable and trustworthy locksmith.


Yours sincerely,


Shelley D 

Mike C, Northwood

I would like to thank Miles for recently upgrading the locks to my patio doors.

The locks were adequate for securing the doors, but were not of sufficient quality to stop a determined person from gaining entry.

Miles supplied and fitted the locks with minimal disruption and educated me in the importance of sensible locks on the doors to my home.

I would encourage a visit from Essential Locksmiths to review your home security.

Louise B, Hampstead Garden Suburb London NW11

Dear Miles,


Thank you for coming along again today. I am very pleased that you found a great solution and that all window locks are working.

Kind regards,

Claudine C, Wanstead London E11

Essential Locksmiths (Miles) were fantastic, arrived on time and text me before they arrived too, friendly and very helpful.


They explained everything before any locks were installed and recommended the perfect solution to my 'non' child-friendly windows.

I would not hesitate to recommend Essential Locksmiths (Miles) and would happily call upon their services again!

Fantastic service, thank you.

Thanks again!


Victoria J, Northwood

Dear Miles,


Thank you very much for fixing the broken locks, and in particular thank you for the help that you gave on the night of the burglary – you were a very reassuring influence at a dreadful time.


Many thanks again for your all your help – you have been wonderful and I will highly recommend you to anyone needing any locks changed!


With kindest regards,



Stephen R, Shenley

Dear Miles,


RE: Locks to XX Xxxxxxxx Xxxxxxx Shenley Herts


Thank you for repairing the locks to our two sets of patio doors.


I found you to be reliable, prompt and efficient and repaired the lock on our patio door, despite being told previously by another locksmith that this was impossible.


I have no hesitation in recommending you to my clients, friends and family.


Many thanks once again.


Yours sincerely,


Stephen R

Michelle S, Woodside Park London N12

- 5 out of 5 - 

Miles was extremely efficient and replaced some lost cupboard keys in a few days. All it took was literally 2 emails. Pleasant and polite, came when he promised he would.

Spencer S, Radlett

Hi Miles

Thanks for doing this quickly.

Really appreciated.

You have done a lovely job. I know it was a bit tricky.



Statons Estate Agents, Radlett

Roy A, Stanmore



I just wanted to drop you a line to say thank you so much for helping Rachael get back into the house.


I was not around to help and she was panicking what with the kids being stuck out in the cold.


Thanks once again - our knight in shining armour!


Best regards,



Michael M, Colindale London NW9

A few days ago, the lock of my front door broke – I could not get into my home.

Although I had my BNI card holder with me – my chapter does not have a Locksmith.

Through another means, my sister gave me some phone numbers of local locksmiths.

It truly was my good fortune that Miles Hartzel of Essential Locksmiths attended my emergency.

He arrived within the stated response time, he was very helpful and so skilful that he opened the door without any damage.

Miles supplied and fitted a new latch within the hour, with the minimum of fuss and left my home without any mess. His charges were reasonable.

Best of all – I found out that he is a member of BNI. He is a credit to his chapter – I only wish I knew him before - so that I could have invited him to join my chapter.

I have no hesitation in recommending Miles Hartzel to everyone who needs a reliable, attentive, skilful and trustworthy locksmith.

Warmest regards,

Michael M

Barry H, Watford

Dear Miles,

Re: New locks

I am writing to thank you for providing such great service today in changing our locks.


Having suffered a breakin overnight we were anxious to prevent a recurrence. You were not only able to attend quickly, but provided us with very good security advice and had all the necessary locks and equipment to get the job done in a professional and friendly manner.


The recommendation to you came via the BNI Network and shows how useful that network is.

With best wishes,

Barry H

Janet W, Hemel Hempstead

Hi Miles,

Phil M, Borehamwood

Hi Miles, thanks for sorting our front door today. It was not pleasant for my wife to be locked inside and she really appreciated your speedy response!



Daryl N, Finchley London N3

Hi Miles


We have now settled into our new home and I just wanted to say thanks for changing all our locks at such short notice. I was worried who may have had keys from the previous owners, but now I can sleep better at night.

A great job, done well.
