Our Terms and Conditions of engagement.

1. Definitions

In these conditions the following words shall have the following meaning :-

“Snelgrove Survey”, “Company”, “Us”, “We”, “Our”, or variations thereof shall mean Snelgrove

Survey Ltd.

“The Client”, “You”, “Your”, or variations thereof shall mean the person, firm or Company with

whom Snelgrove Survey Ltd contracts.

“Goods” means the articles or things or service which are the subject matter of the Contract (eg

Vineyard Mapping, Vineyard Surveys, Field Mapping, Crop surveys etc)

2. Order Acceptance Policy

2.1. Snelgrove Survey reserves the right at any time to accept or refuse service and sales for any

reason. Snelgrove Survey reserves the right to require additional verifications or information from

the purchaser before accepting any order or providing services. You agree that the receipt by

Snelgrove Survey of an electronic or printed copy of an order form does not indicate Snelgrove

Survey acceptance of the purchaser’s order, neither does it constitute confirmation of Snelgrove

Survey’s offer to supply services.

3. Quotations

3.1. Written quotations are valid for up to 30 days (unless agreed otherwise) and will be supplied for

all work on receipt of a clear and accurate written brief from the Client. Written briefs are required

to ensure survey objectives are well defined for both the Client and Snelgrove Survey and to avoid

errors. The brief may need to include, but is not limited to, full postal address with postcode, maps,

site plans with boundaries and the North compass bearing clearly marked, Ordnance Survey Grid

references (6-figure) and any other material required to accurately identify the site from the air.

3.2 . The quotation and fee will be inclusive of all preparatory work, provision of any written

documentation (eg. Method Statements and Risk Assessment where required) or permission

required (e.g. by the Civil Aviation Authority, Air Traffic Control, Police and relevant landowners),

travel and accommodation (where necessary) and post-production processing work (not normally

included) and digital delivery of the survey. For UAS work, unless otherwise stated, the quotation

will be for the amount of aerial survey reasonably achievable within one day.

4. Payment Terms

4.1 Terms of payment are within Snelgrove Survey’s sole discretion, and, unless otherwise agreed to

in writing by Snelgrove Survey, full payment is due in full on receipt of invoice. In the case of work

being required by the client to be done in phases, Snelgrove Survey reserves the Right to partially

invoice at stages and request an initial deposit (“Deposit”) prior to the commencement of any work

due to be undertaken. Snelgrove Survey reserves the right to add statutory Late Payment Interest

(Base Rate + 8%) to overdue accounts [Late Payment of Commercial Debts (Interest) Act 1998].(see

4.6)

4.2  The Client shall pay Snelgrove Survey, the fees and other amounts as outlined and agreed in the

quotation. Any additional work requested that has not been previously agreed upon or that has not

been included in the initial quotation, will be charged for on a ‘time and hire’ basis calculated on the

basis of Snelgrove Survey’s standard rates . 

4.3 Snelgrove Survey reserves the right to amend any quotation prior to both parties being in

agreement or based on any new information which comes to light from either a site survey or

prevailing weather conditions or consent of any location owners, or requirements for additional

equipment and/or time and/or Operatives to ensure the safe and professional operation of the

Services. 

4.4 Snelgrove Survey’s pricing is based on survey charges being calculated on task circumstances,

location, actions required, equipment and operators needed (pilots, observers, assistants).All survey

and other charges will be calculated on this basis, unless previously agreed in writing.

4.5 Upon Snelgrove Survey being satisfied that the Services have been completed in full or in stages

(or in advance of this at Snelgrove Survey’s option), Snelgrove Survey will issue an invoice, or

invoices, to the Client for the fees and charges then due. The Client will make payment for all sums

due under an invoice in full, and in cleared funds, in the method set out on the invoice, upon receipt

of invoice (unless Snelgrove Survey and the Client agree an alternative time frame, in writing). 

4.6 Unless previously agreed, any amount due to Snelgrove Survey that is outstanding after the due

date for payment will attract interest at the rate of 8% per month above the base rate of The Bank of

England until the full amount has been paid. Such interest charges will be compounded at the end of

each month. 

4.7 Snelgrove Survey may deduct the amount of deposit (if any has been paid to Snelgrove Survey)

specified in the service Agreement from the final invoice(s) to the extent that such deposit remains

unused.

4.8 Once a booking has been made, if at any time the Client no longer wishes to receive the booked

Services (or any part of the Services) Snelgrove Survey reserves the right to charge a cancellation fee

not exceeding the total amount that would have been paid Snelgrove Survey under the service

Agreement had the Services been completed. 

4.9 The Client shall procure that upon request from Snelgrove Survey, the Client’s director(s) enter

into separate guarantees with Snelgrove Survey whereby they irrevocably and unconditionally

guarantee to Snelgrove Survey the due and punctual performance of the Client’s obligations under

the service Agreement. In addition, if the Client defaults in payment of any sum or sums payable to

Snelgrove Survey under the Agreement for a period of more than 60 days from the invoice date, the

director(s) of the Client will upon written request from Snelgrove Survey pay such sum or sums as

may be outstanding under the service Agreement. In the event of there being more than one

signatory to this guarantee, the directors’ liabilities shall be construed and have effect as joint and

several liabilities.

5. Site

5.1. If a site survey is needed prior to the quotation, the cost will be agreed and invoiced in advance

(unless agreed otherwise). The Client must confirm in writing that it has permission to access the

ground that will be used to take off and land. If a client cancels our services after accepting a written

quotation, the Risk assessment fee will be still be valid and chargeable to the Client due to work that

has to be undertaken prior to any flights or survey being performed by Snelgrove Survey on behalf of

the client.

6. Cancellation by Snelgrove Survey

6.1 If Snelgrove Survey cannot fly/survey due to adverse weather conditions or mechanical failure,

cannot fly due to reasons that only become evident once on site or for reasons that Snelgrove

Survey was not advised of beforehand, then a partial cost will remain due for payment to Snelgrove

Survey. Snelgrove Survey will make every reasonable attempt to complete any tasks missed due to

any of the reasons highlighted, within 28 days of the missed task.

7. Cancellation by You

7.1 Notice of cancellation by the Client must be received in writing by Snelgrove Survey and the

Notice is not valid until confirmed in writing by Snelgrove Survey. Cancellation fees are payable

according to the following schedule:

7.1.1 Three or more days notice – 40% of the agreed fee less any payment already made.

7.1.2 Two days or less notice – 60% of the agreed fee less any payment already made.

7.1.3  Notwithstanding the above schedule, if any costs have been incurred by Snelgrove Survey

following written instruction from you (for example, but not limited to an agreed Site Survey cost,

additional operators, specialist equipment) these costs will remain due for payment in full.

8. Permission to conduct survey

8.1 Flight permission is generally granted within a day or so, however with UAS surveying,

permission from the Civil Aviation Authority (CAA), local Police, other authorities and relevant

landowners, when needed, can take several weeks (CAA may require up to 28 days written notice of

intention to fly). This is usually granted but certain height and/or other conditions may be applied).

All work is subject to obtaining permitted and legal access from which to safely operate the UAS

equipment.

9. Limitation of Liability, weather, Force Majeure, Act of God and Other constraints

9.1 As with any outdoor survey, a successful outcome depends upon suitable weather conditions. A

decision to survey on a particular day is normally delayed to the last practical moment to maximise

the chance of suitable weather. Should the weather on the day not be as forecast and the

assignment needs to be postponed, or there is some other reasonably unpredictable reason why the

work could not be completed , then either there will be no additional charge to the Client for a

return visit to complete the work or the Client can request a full refund of monies paid to Snelgrove

Survey in respect of the cancelled time. No refund will be made for any chargeable preparation work

already carried out.

9.2 The UAS and camera weigh approximately 1Kg. Whilst the UAV has build-in self-stabilising

measures, it is a flying platform and is subject to movement by the wind and will tilt whilst being

held against the wind. This will impact on the image quality, steadiness and the angle of the survey

images. We will endeavour to obtain the best imaging for the conditions. 

9.3 If the work could not be completed due to Client reasons (e.g, but not limited to, lack of access

or unscheduled site activity etc), the Client may be charged to recover costs and time.

9.4 Snelgrove Survey will always endeavour to complete its assignments by proposed completion

dates. However, due to weather and other operational constraints, Snelgrove Survey cannot

guarantee completion on or by any specific date. It, therefore, cannot be held responsible for any

missed deadlines or any consequential costs involving the timing of the commission.

9.5 Battery limitations mean that each flight will last a maximum of approximately 35 minutes. After

this time, the UAV must descend for a battery change.

9.6 In exceptional circumstances, Snelgrove Survey may not be able to completely fulfil or complete

a contract at all. In these cases, it will refund part or all of any deposit received and not accept any

other liability. In any event, the liability of Snelgrove Survey will be limited to the total value of the

contract with no liability accepted for indirect and/or consequential loss.

9.7 Snelgrove Survey does not accept liability for errors resulting from incomplete or inaccurate

instructions from the Client’s written brief, nor for delays or restrictions caused by Air Traffic

Control, CAA or the Police or similar Bodies.

9.8 Whilst back-up copies of images are usually kept, Snelgrove Survey accepts no responsibility nor

liability for maintaining archive copies of survey material after the work has been delivered to and

accepted by the Client.

9.9 Snelgrove Survey has all necessary insurances, including Public Liability Insurance, with an

indemnity of up to one million pounds. Increased indemnity is available at the request of the Client

but will be charged to the Client.

9.10 Snelgrove Survey does not accept liability for errors resulting from incomplete or inaccurate

instructions from the Client’s written brief, nor for delays or restrictions caused by Third Parties.

9.11 Snelgrove Survey and its agents shall be under no liability for any injury, loss, or damage of any

kind whether direct, consequential or special and howsoever caused resulting from or arising out of

or incidental to:

9.11.1 Any negligence on the part of Us (except insofar as the same causes death or personal injury)

or

9.11.2 Our performance of or failure to perform or breach of any of its express implied obligations

under the Contract.

9.12 You shall indemnify Us against any liability whatsoever (including any liability based on the

negligence of You) which it may incur resulting from any claim made against You by any third party.

9.13 We accept no liability for delay or non-fulfilment of any term of the Contract caused wholly or

in part by “force majeure”, which expression shall be deemed to include war, strikes, lockouts,

accidents, fire, scarcity or materials or any other cause or causes not within Our direct control.

10. General Conditions

10.1 No failure or delay on the part of us to exercise its rights under the Contract shall operate as a

waiver thereof nor shall any single nor partial exercise of any such right exclude any other or further

exercise thereof. Any waiver of a breach of any provision of the Contract shall not affect Our rights in

the event of any further or additional breach or breaches.

10.2 Notwithstanding termination of the Contract these Conditions shall continue in full force and

effect for so long as is necessary after such termination to give full effect to the provisions contained

in these Conditions

10.3 The Contract shall be construed in accordance with English law which shall be the proper law of

the Contract and the English Court shall have sole jurisdiction in relation to the provisions contained

in these Conditions.

10.4 The clause headings in these Conditions are for convenience only and shall not affect the

interpretation hereof in any way whatever

10.5 Each and every obligation contained in the clause or sub-clause of these Conditions shall be

treated as a separate obligation and shall be severally enforceable as such and the non-

enforceability at any time of the clause or sub-clause of these Conditions shall not prejudice the

enforceability of the remainder.

10.6 These Conditions are stipulated by Us on Our own behalf and on behalf of all agents and apply

for the protection of all its agents as for Us. The Client undertakes not to sue or make any claim

whatever against any of us or agent of Us in respect of any alleged negligence or other default of

that Us or agent in relation to the carrying out, failure to carry out or breach of any Contract.

10.7 The Client acknowledges and agrees by placing orders with Us that:
