Dear Johnathan

Please find below my quotation for the installation of a photovoltaic system 2.5 KW peak comprising 10 JASolar JAM6-60 /LG250SIC panels mounted on one south facing roof .

I have simulated the returns for each proposal using both the Standard Assessment Procedure laid out in themcs certification guidelines and also with the aid of dedicated specialist analytical software created by thephotovoltaic department of the University of Geneva PV Syst. I have attached the simulations and thecalculations for the financial returns.

I have summarised the results for your convenience in the table on page 3.

Please be advised that in order to qualify for the feed in tariff the property will need to demonstrate anenergy efficiency level of D or above via an energy performance certificate. Complete Plumbing Cleanenergy will be very pleased to carry out this survey for our standard fee of £75.00 + vat .Following the carrying out of the survey should works be required to upgrade the property we will be in aposition to advise you of the most cost effective measures to take, provide quotations for carrying out theworks and put the works into effect speedily and efficiently.

Please also re advised that a roof report by a qualified professional will need to be provided In order to verifythe load bearing capacity of the roof structure. This is a requirement of the MCS process to validate thesystem to qualify for the Feed in Tarrif. Again complete Plumbing can provide this report for our standardfee as detailed in the estimates provided.

Please also be advised that planning permission may be required for this installation. Complete Pluming hasdnot carried out planning enquiries for this installation. Should you wish us to make planning enquiries onyour behalf we shall be able to do so, charges may apply.

Please also be advised that should you wish to proceed we will ask for a 40% deposit and ask you to sign ourstandard custom agreement which we have attached for your attention.

Kwh stands for kilowatt hours which is the unit electricity usage is measured in. The Feed in tariff pays 43p at current levels for each unitgenerated by the system plus 4p for half the total generated which is assumed will be fed back to the grid. In addition it is assumed that halfthe total will be used in the property and so will yield returns from using your own electricity rather than buying electricity at 13p a unit from

your electricity supplier.

Notes for your attention:

Please be advised that it is an assumption of our quotation that the roof structure is of suitable construction and state of repair asto be sufficient to support the installation of your solar panels. Our quotation will not normally allow for a structural survey ofyour roof. Should you have concerns about the roof structure we will be happy to commission a survey on your behalf.Otherwise complete plumbing clean energy cannot accept any responsibility for the structure of the roof beyond ourprofessional responsibility to ensure that the roof is not compromised in any way by the installation of the solar panelsthemselves.

Should at the time of installation our engineers become concerned about the state of the roof or the roof timbers we will bringour concerns to your attention and seek to agree with you a suitable way forward.

Should you agree to our quotation we would seek a deposit of 40% of the total value of the contract. Should the roof beunsuitable for the installation of the panels or work required to increase the load bearing capacity of the roof be uneconomic adeduction of £350 will be made to cover costs of the survey and the deposit returned.

Following the installation of the system Complete Plumbing will seek payment in full for all works carried out and materialssupplied. On receipt of payment in full Complete Plumbing will issue within 48 hours issue a mcs certificate and record theinstallation on the OFGEM database. The owner of the system will send the mcs certificate to the electricity supplier and fromthat date will be eligible for the feed in tariff payments.

Please be advised that in a situation where additional works beyond these estimates become advisable or necessary charges willbe applied on a strictly time and materials basis the rate for which is included in the text of your quotation.

Important Note Please be advised that while we would not expect the installation to require planning permission, as planningpermission is normally only required for listed buildings or areas of outstanding natural beauty. However in some areasplanning permission may be required for flat roof installations. We will not make planning enquiries unless specificallyrequested to do so. Should you wish us to make such enquiries Please inform us in writing. Charges may apply.

Our panels are great

Thanks for helping out where others couldn’t. It’s a relief to find someone who understands the complexity ofmodern home energy systems and is able and willing to work out best solution for every site.Will AndersonSW2

Installation was completed very helpful and efficient within a couple of days, and my solar panels were up andrunning straight away. Thank you. Your service is brilliantCharmian KennerSW2

Complete Plumbing and Heating Service Ltd played a major part as a sub-contractor. Their standard of workwas very good and included the installation of the Solar and Photo Voltaic panels with related pipework andequipment as well as the more general plumbing work.

The project was completed very satisfactorily within budget and with the submission of a reference manuallisting the work done. On completion the Company provided a briefing explaining the system and the controlmethodology. We were very pleased with the quality work and helpfulness of all involved.

Peter CobleySW4

We asked three companies to provide us with an estimate to install PV panels, CPHS was not only the mostthorough of the three in terms of survey they undertook but they also came up with the most cost effectiveproposal. The installation went pretty smoothly and the system works well.

Richard SeagerManagement ConsultantSE22

Very Happy. Job done professionally. Very high standard of workmanship. Cooperative team of installers.

Found them highly experienced in the field of solar and underfloor heating. I would highly recommend this

company without any doubt. Pleasure to do business with Nick Cotton.
