If during the course of the works these change for any reason it is the responsibility of the client to notify the Approved Inspector of these changes.

    The Approved Inspector will notify you of any other drawings, calculations, specifications or certificates, necessary to complete our work at the appropriate stages. The preferred format is pdf

2.6. It is the client’s responsibility to contact the Approved Inspector to inform us that works are due to commence and at each key stage as listed in the stage notification plan. The stage notification plan is not a list of actual inspections that will be carried out, but rather the stages at which you must notify us, it therefore does not reflect the number of inspections that may be carried out.

2.7 . The client shall make available during normal working hours proper access to the site in order to carry out inspections of work in progress.

2.8   The Client shall ensure that reasonable and safe access to the Project site and facilities are provided, at all reasonable times, to allow employees of the Approved Inspector  to make necessary inspections.

2.11. It is the client’s responsibility to notify the Approved Inspector upon occupation and completion of work to enable us to carry out a final inspection.  Failure to inform us of completion resulting in cancelled visits or additional administration may be subject to additional charges.

2.12 If works are covered without inspection and if considered necessary, the Approved Inspector reserve’s the right to request completed works to be uncovered to show compliance with the Regulations. The client shall be responsible for uncovering such work and/or providing other evidence to the satisfaction of the Approved Inspector.

2.14.    The Client shall be entirely responsible for the design, construction and management of the Project and any additional  work beyond the Services.

2.15. If the client materially breaches their obligations under this agreement or fails to respond to any notification of a breach of Building Regulations the Approved Inspector may terminate this agreement by giving written notice to the client. This would also result in the Initial Notice being cancelled.

2.16 The client should be aware that due to the time limits imposed by regulation 17 of the Regulations an Initial Notice can cease to be in force as a result of completion or occupation of a building prior to the issuance of a Final Certificate. It is the responsibility of the client to insure that any remedial works or commissioning certificates are provided in a timely manner and in no case should this exceed 8 weeks in the case of a domestic building, or 4 weeks in the case of a building to which the Regulatory Reform (Fire Safety) Order applies, without an agreed extension of time being in place.

3. Cancellation of Initial Notices

3.1.    The Approved Inspector may cancel the Initial Notice by sending a Notice of Cancellation (as described  in the Regulations) to the local authority in the following circumstances:

  1. a) after a formal Notice of Contravention (as described in the Regulations) has been served and no action has been taken by the Client to regularise the contraventions within 3 months;
    b) the Client or its agents place undue restrictions of The Approved Inspector  thereby preventing The Approved Inspector  from carrying out its Services and legitimate functions as approved inspector for the Project;
    c).   The Approved Inspector  is prevented from making site inspections due to dangerous or unsafe conditions;
    d).   failure on the part of the Client to submit plans or other relevant documents  in a reasonable period of time;
    e) the expiry of time limits set out within Regulation 17
    f) works not having commenced within a period of 3 years form the date of the submission of the initial notice
    g).   any other condition or situation that prevents The Approved Inspector  from carrying out their function as an approved inspector; or
    h)   failure of the Client to pay the necessary fees.

3.2.    If any of the above circumstances occur and the Client shall still be liable to pay the Approved Inspector  any instalments of the Fee due up to the date of termination together with a fair and reasonable proportion of and any additional services performed by the Approved Inspector  up to the date of termination or required thereafter (such as archiving and storage).

4. Terms of Payment

4.1.    All fee quotations provided are valid for 30 days from the date of issue.

4.2. In consideration of the provision of the above services, the client will have provided a reasonable estimate of the program  and cost of the works  which is based on:

a) An amount which relates to the `building cost’. This figure should include the cost of labour and materials which would normally be provided by a contractor in business, If there is any dispute regarding the estimated cost, the RICS cost information figure shall be used to determine the estimate

b) Project duration and phasing

4.3 Should the work extend significantly (eg 10%) beyond the agreed work boundaries or the estimate of the cost of the work, then an additional fee is payable based on £ 75.00 per hour or revised estimate, whichever is the most appropriate. In the event that you (or your contractor) request an inspection of work which is incomplete or abortive we reserve the right to charge an additional fee if this results in additional work for the Approved Inspector.

4.4  Fees have been based on the contract value and duration as detailed above and are payable upon appointment as Approved Inspector. Upon receipt of the contract an invoice will be raised and the Initial Notice will be served on the appropriate local authority.

4.5 By signing this contract you are authorising the Approved Inspector to sign the Initial Notice on your behalf. In the event that the works are abandoned part way through the appointment no refund will be made of fees invoiced, however, no additional invoices will be raised.

4.6 Fees should be considered as application fees and are payable in advance of the work being completed. We cannot agree to fees being paid contingent on works being completed as this would be a conflict of interest, as  we would be under pressure to sign off non-conforming work in order to be paid.

4.7 Fees under £1000 (exc VAT) will be charged as a single payment unless we have indicated otherwise. Fees over £1000 (exc VAT)  will normally be charged as a plan checking fee and a site inspecion fee.

4.8. The `due date for payment’ shall be 7 days after the date of the submission of the invoice, we offer credit terms as stated below. The Approved Inspector when submitting his invoice shall on each invoice confirm the basis on which the stated amount is calculated as above.

You agree to pay us interest on any unpaid fees from the date one month after the bill is rendered at 3% per annum above Barclays Bank plc base rate as at the date of the bill.  Further, if you have not paid us within 45 days you agree to pay a charge for collection, namely £40 on debts under £1000, £70 on debts over £1000. After 45 days we will instruct a solicitor to write to chase any outstanding debt.

4.10 I f an invoice remains unpaid without challenge for 60 days from issue, the Approved Inspector may suspend service in relation to the project by notification to the client in writing.

4.11 If an invoice remains unpaid without challenge for 90 days from issue, the Approved Inspector may formally terminate involvement with the project and cancel the Initial Notice. The Approved Inspector shall have no liability for any costs, damages, delay, expenses, fees, works etc. that arise out of such a cancellation of the Initial Notice.

4.12.  All orders should state the address for invoices and, where required, the address to which the invoice is to be copied. If you are a company or partnership or other trading body and fail to provide this information we will carry out a search at Companies House to ascertain your registered office and serve the invoice to that address.  In the case of an individual we will serve the invoice at your home address.

4.13 . Where an order is placed on behalf of a third-party, you must take responsibility for payment. If there is more than one of you instructing us, you agree that you will be jointly and severally liable for payment. If you are an agent please take legal advice if you are in any doubt about responsibility for payment or ask your client to sign the form themselves.

4.14. We will undertake a credit agency check prior to commencing work. If the credit rating indicates that the credit limit is less than the value of our fees we may require cleared payment in advance of commencing work. If you prefer not to have a credit search please provide a cheque with the appointment form.

4.15 All fees are quoted are excluding VAT and disbursements unless otherwise stated.

4.16. If we have not given you a fixed fee, there are different hourly rates depending on the status of the person carrying out the work and the nature of the work. Work will be billed in hourly units and the rate will be clearly stated on our invoice. Time, time spent travelling (E.g. by train, car, underground etc) is, in the absence of agreed arrangements, charged at the hourly rates as above. Fares, hotel accommodation and out of pocket expenses are charged at actual cost. Petrol and running expenses may be charged at 40 pence per mile travelled.

4.17 Unless otherwise agreed, work carried out on an hourly basis will be invoiced at the end of each month.

4.18 Where Design Information is submitted by e-mail, a charge to cover the reasonable printing costs may be made which is in addition to the agreed Fees. This will not apply where The Approved Inspector  are notified in writing, prior to providing a quotation, where the cost of printing will be inclusive.

4.19 All fees must be paid in full prior to the issue of a final certificate.

4.20 If the Works commence on site and The Approved Inspector  have made an inspection following which the project is abandoned, then The Approved Inspector  will be entitled to the full amount of the total Fee.

4.21 If the scope of the Works change or the address or other information change during the project from that contained in the data collection form, to an extent that it becomes  substantially different to that described  in the Initial Notice, then the Approved Inspector  shall be entitled to additional payment.

4.22.  In the event that the Project becomes unduly protracted, the Approved Inspector  reserves the right to seek additional costs for its Services. In this respect the Approved Inspector  will contact the Client to agree in writing such payments.
