Appointments, access & timekeeping

Appointments can only be made by persons over the age of 18. Where an appointment is made by mrStat, this appointment will be confirmed via email. Once a confirmation email has been sent, mrStat will be liable for attending such an appointment unless the client is informed prior to the given arrival window of such an appointment is due to begin. In the event that an appointment cannot be upheld and where mrStat has informed the client of this action prior to the window for the appointment, no monies or compensation will be owed. In the event that an appointment cannot be upheld and where mrStat has not informed the client of this action prior to the window for the appointment, a compensation amount of £25 will be payable to the named client on the appointment booking except in the event that an address cannot be found or does not exist. No additional compensation may be claimed. Claims should be submitted in writing via email to info@mrst.at including the booking reference.

Where mrStat attends an appointment at an allocated time and is unable to gain access for any reason, a message will be sent to the mobile phone of the person who booked the appointment informing them of failed access. No charge will be applied. In the event that an appointment is then rescheduled and a further visit is made where no-access can be gained, the full fee of the agreed service will become payable prior to any additional visits being organised or attempted. This payment will be non-refundable and on receipt a third visit will be organised and attempted. In the event that a third visit is attempted without access, no additional visits will be made to the property and no funds will be returned.

There must be an adult (Person above the age of 18) at the property for the duration of the visit. This person must have decision making abilities and permission to agree works or ammendments prior to proceeding. Where there is no person above the age of 18 or a person that does not have permission to make decisions is present, a no-access will be recorded against the property.

Where an appointment is made through the online booking system at mrstat.co.uk the appointment will not be considered as confirmed until an email has been sent to the booking party. mrStat reserves the right to ammend any booking and/or appointment up and until the start of the appointment window.

Where this work takes longer or where the consenting party does not agree with the duration of the booking and wishes to cancel the appointment, a no-access will be recorded against the property.

The work undertaken by mrStat may include noise making processes and may require access to every part of a property. Where this is not possible, not practical or restricted, mrStat reserves the right to reschedule an appointment to a more suitable time. A no-access may be recorded against the property in this instance at the sole discrection of mrStat.

mrStat will endeavour to clean all mess created by the works agreed and will limit where possible debris, noise and rubbish, however no liability is taken for dust, debris and rubbish left behind and the areas of work may need wiping down or hoovering on completion.

Where holes are made, materials removed or damage incurred to a property in order to complete the works agreed, no decoration, making good or repair will be offered or be the responsibility of mrStat. The booking party and/or the person(s) allowing access on the day acknowledge that due to the nature of work, minor repairs may be neccessary on completion to which they will be responsible for.

During works, electrical supplies, heating, hot water and in extreme circumstances water supplies may be interrupted. No compensation for interruption of services will be made available. mrStat will be liable for re-instatement of such services on completion of the works (See "Existing services" for additional notes).


All advice offered by mrStat is done so in good faith. It is ultimately the client's responsibility to undertake their own research and come to their own conclusions as to the products being requested for installation.

Where advice is offered by mrStat for the purposes of fault identification and rectification, it is acknowledged by the client that all repair prices offered will be an estimate and subject to change. As repairs are carried out it is possible that additional issues may be identified and where encountered there may be additional charges which will be agreed with the client at the earliest opportunity, where the client does not agree to rectify further issues, no liability by mrStat can be taken in the event that the repair can be satisfactorily made, the original advised work will remain chargeable.

In the event that a client wishes to proceed with work whereby mrStat has advised against completing the work, mrStat reserves the right to refuse and where work is completed against the advice offered, mrStat shall not be held liable for any outcomes.

Rubbish & defunct equiptment

Where controls or accessories are removed from operation during the works, the responsible party will be given the option to keep such items. In the event that they decline, these items will be considered as waste and removed from site for disposal.

Where cables, clips, screws and miscellanious debris are removed during the works, these items will be considered as waste and removed from site for disposal. The responsible person must inform mrStat in the event that they wish to keep these items.

All items classified above as "waste" will be removed from site and disposed of via green means, where possible mrStat will arrange for and pay for recycling of all such items by an approved waste carrier. Once removed from site, waste items will be considered the property of mrStat until such handover to a waste carrier whereby all ownership rights shall transfer to the arranged waste carrier. No items can be returned or will be compensated for once removal has taken place.

In all instances, mrStat will not be held liable for damages to paintwork, carpentry, floor coverings, wall coverings, decorative features or items of similar nature where damage is inflicted in order to complete the tasks required to complete the works.

It is the client's responsibility to ensure the working area for mrStat is sufficiently clear from personal effects. The client acknowledges that any damage to personal effects except where caused by negligence on behalf of mrStat will not be compensated for. Where compensation for neglect is owed, it shall be limited to twice the value of the works agreed.

Existing services

Works carried out by mrStat may include works to the electrical circuits, heating system, hot water system and potentially the plumbing within a property. These services must be in a safe, well maintained condition prior to works being requested by the booking party. In the event that an installation is not considered to be of a satisfactory standard, mrStat reserves the right to refuse or discontinue with the works.

In the event that mrStat identifies an unsafe situation as defined by the Gas Installation & Use Regulations currently enforced or whereby an electrical installation is deemed unfit for operation, the unsafe components and where applicable it's associated services may be disconnected and/or rendered safe. mrStat will accept no liability for the loss of service and will not be liable for the rectification, replacement and/or repair of such item(s). Where works have been completed but due to inherent safety risks present the associated equipment cannot be re-instated, the full balance for works will remain payable.

No liability for the repair and/or replacement of components and/or appliances will be accepted by mrStat and where works have been deemed as complete by mrStat, any amounts owed will become due. In the event that works cannot be completed, it shall be at the descretion of mrStat as to whether or not payment is owed or whether a no access charge should be applied to the property.

The technology and service(s) deployed by mrStat may alter the way a system works. It is accepted by the booking party that they have conducted their own research into the technology which is to be installed and they accept liability for any outcome. Where a client is not entirely satisfied with the works completed by mrStat but this can be attributed to the functionality of the equipment installed and where any such equipment has been installed to the manufacturer's instructions, no liability can be accepted by mrStat.

High risk activities

Where works being carried out are considered high risk (Converting low pressure to high pressure, powerflushing, work in restricted places [Underfloors or in walls], etc), mrStat is unable to accept liability for existing services not functioning correctly on completion or from leaks being created. Where possible, mrStat will repair or replace as needed any existing services that fail at the time of the visit at an additional charge, however any damages caused will not be considered as negligent and mrStat will not be held liable for any subsequent repair works.


mrStat reserves the right to request a deposit for any works prior to attendance. Deposits will be refunded in the event that the client wishes to cancel the works and notification to mrStat in writing (Sent to info@mrst.at) is received by mrStat 24hrs in advance of the appointed window of arrival or where mrStat has declined the works for any reason except where a no-access charge has been applied to a property (See Appointment and Access terms above).

Where a deposit is requested for the purchase of special order materials or larger volumes of stock and the works are cancelled for any reason, mrStat reserves the right to deduct upto 15% of the total materials value of the job to cover restocking fees applied by merchants, this fee can vary from merchant to merchant. No restocking fee will be applied in the event that mrStat cancels the appointment.

Where monies are owed on completion of the works, payment is preferred via chip and pin credit/debit card or cash. No other forms of payment will be accepted except Crypto Currencies where additional information is outlined within the Crypto Currency page. All monies owed will be due at the time of completion.

Where legal action is undertaken, the booking party will be liable for full payment along with all costs incurred by mrStat in undertaking the debt recovery process.

When payment in full or part is to be made via a Crypto Currency, details of additional requirements will be displaid on the Crypto Currency information page. Due to the volatility of Crypto Currencies, this method of payment varies day by day and is subject to editing at anytime. mrStat reserves the right to withdraw Crypto Currency acceptance at anytime without notice, however any monies paid via this method will be held inline with the agreement laid out on this page at the time of the transaction.

Where pre-agreed, credit may be available. It is the booking party that is responsible for all costs and where payment terms are not adhered to, a non-payment administration charge of £15 will be applied along with interest at a rate of 8% plus the Bank of England base rate on the total owed balance added every week that the balance remains outstanding from the default date of the credit being agreed to be settled. Where legal action is undertaken by mrStat, the booking party acknowledges they will be liable for all costs incurred by mrStat to carry out the debt recovery process.

Where payment is not possible due to a technical or network failure with the payment processor, cash payment should be made available, however mrStat will work with the booking party to settle the debt with no additional costs to the booking party being applied, this is offered at the sole descretion of mrStat and may result in a verbal credit agreement to settle the balance at a later date within a set time period.
