Terms and conditions

These are the terms and conditions on which I will supply services or goods to you, including digital and online content.  Please read these terms carefully before you submit your order. These terms tell you about how you and I may change or end our contract, what to do if there is a problem and other important information. If you think that there is a mistake in these terms, please contact me to discuss.

Information about me

I am Jon Isaacs, Chartered Engineer, trading as a Sole Trader using my own name for my business activities which may be written in various forms including J. Isaacs and Jonathan Isaacs. My trading address is also my home residence which is 20 Vine Street, Worcester, WR3 7DY, UK.

I may use various means to contact you including telephone, email or postal address details you provided in your order or enquiry. When I use the words “writing” or “written” in these terms, this includes emails.

Our contract

My acceptance of your order will take place when I accept it, at which point a contract will come into existence between us. This may be verbally or in writing. If I am unable to accept your order, I will inform you of this and will not charge you. 

Your rights to make changes 

If you wish to make a change to your order, please contact me as soon as possible. I will let you know if the change is possible. If it is possible, I will let you know about any changes to the contract as a result and ask you to confirm whether you wish to go ahead with the change.

My rights to make changes

I may change the contract to reflect changes in relevant laws and regulatory requirements and to implement minor technical adjustments and improvements.  These changes will not adversely affect the service or product.

Descriptions of products and services can be found on my website and, whilst I have made every effort to make sure these are accurate, they are subject to update and change.

Executing our contract

During the ordering process, I will confirm when the service or product is scheduled to be delivered. If there is a delayed by an event outside of my control, I will inform you as soon as possible. I will take steps to minimise the effect of any such a delay and tell you how I intend to do this. I will not be liable for any financial compensation regarding delays which are outside of my control.

I will endeavour to execute the contract as agreed within the scope of our contract and within all legal and safety constraints that may apply at the time.

If you are not able to allow access to your property to enable the contract to be completed as arranged, then you may be liable for the full charge of the contract and additional charges to enable the contract to be executed at an alternative time.

I will not be responsible for late supply if this is caused by you not providing the information I need within the required timescale.

I will ask you to sign-off the contract as complete. You must satisfy yourself that the work has been completed to your full satisfaction as additional work after sign-off may be chargeable. 

Title and Risk

You do not own any goods or services that I supply until I have received full payment for them. I reserve the right to collect any goods which have not been paid for in full or take recovery actions regarding unpaid invoices.

Any goods or services which may be supplied before payment is made in full, remain entirely my property but the risk (such as the safe keeping, insurance and health and safety) is entirely your responsibility.

Your rights to end our contract

If what you have bought is faulty or not as described, you may have a legal right to end the contract or to get the product repaired or replaced or a service re-performed or to get some or all of your money back.

If you have just changed your mind, you may be entitled to a refund if you are within a cooling-off period, but this may be subject to deductions and you may have to pay the costs of return of any goods, which must be returned in the original packaging and in a saleable condition.

In all other cases you may end the contract immediately and I will refund you in full for any products which have not been supplied, provided that:-

a) I have told you about an upcoming change to the service, goods or these terms which you do not agree;
b) I have told you about an error in the price or description of the product you have ordered and you do not wish to proceed;
c) there is a risk that supply of the products may be significantly delayed because of events outside my control; 
d) I have suspended supply of the products for technical reasons
e) you have a legal right to end the contract because of something I have done wrong. 

You do not have a right to change your mind in respect of:

a) bespoke items or items that I have already ordered specifically for you;
b) digital products or services after you have started to download or stream them;
c) services, once these have been completed;

My rights to end our contract

I may end the contract for a product at any time by writing to you if:

 a) you do not make any payment to me when it is due

b) you do not provide me with information that is necessary for us to provide the service or goods;

c) you do not allow me to deliver the service or goods

d) I write to you to let you know that I am going to stop providing the service or goods.

Copyright, Intellectual Property & Privacy

All information exchanged between us (including ideas, discussions, concepts , videos, and other non-tangible assets) will be treated as confidential by both parties and will not be shared with 3rd parties or re-used for any other purpose whether or not a formal contract exists. 

Also see my Privacy Policy about how I store and process your data.

Onsite Work

There must be at least one person aged  at least 18 years old onsite for the whole time I am in attendance

I am required to wear suitable personal protective equipment at all times when working onsite. This includes safety shoes and you should take adequate precautions to protect delicate floor coverings or make arrangements to move equipment into an area where the wearing of safety shoes is permitted before our arrival on site. I may use a variety of hand tools, test equipment and oil based lubricants as required during my activity and you are responsible for protecting or removing valuable or delicate items from the working area (including access routes) such as pictures, ornaments, light-coloured carpets or floor tiles that may be prone to marking or damage.

You are required to keep yourself and others a safe distance away from our activity since there may be sharp edges, exposed moving parts and mains voltage present. This especially applies to  vulnerable people, children and/or pets.

You must not touch or interfere with any equipment that I am working on unless I specifically tell you it is safe to do so.

You must not remove any “out of order” signage or reconnect any equipment that I have disconnected.

If your machine needs to be lifted or moved then I will need to assess the risks involved including weight, dimensions, quantity, distance, terrain, steps, weather, and access route (eg. door widths, heights and corridors). You must tell me about these details beforehand so that I can assign appropriate lifting aids and make provisions to minimise any potential risks. If I find that the risks are too high on the day then I will refuse to lift or move the machine.

You are required to provide a safe working environment for me. Your equipment should be clear and easily accessible and the working area including access/egress should be free from obstructions, well-lit and adequately maintained so that I can conduct my work in a safe manner. Electrical sockets should be fully operational and free from damage. I will not work in an environment that is deemed unsafe and you will be charged for the visit.

You should not use any machine or equipment that I have deemed to be faulty or unsafe. If you do so that will be at your own risk.

Some faults can result in the power tripping off in your property. You are required to be familiar with the procedure for safely resetting the power in the event of it tripping off. You should also arrange to disconnect or safely shutdown any devices (such as computers or alarm systems) that may be adversely affected by a sudden and unexpected loss of power

If the contract involves an onsite repair for a fault which only occurs in very specific circumstances (such as at maximum speed after 20 minutes of continuous use) then I recommend that you have the machine prepared with the fault showing for when I arrive as you will be charged for the visit whether or not I am able to witness the fault.

In some cases, onsite repairs by nature can cause under lying faults to emerge that may not have been apparent before my visit. Therefore, I cannot guarantee to be able to leave your machine in the same condition as before nor do I accept any liability for correcting faults which are not part of the scope of our contract.


No warranties or guarantees are provided unless specifically stated. Where applicable, warranties are valid only in mainland England and Wales and the warranty period starts from the first date of delivery of the goods or services. Any work completed under warranty does not suspend, extend or reset the remaining warranty period.
