These Conditions are important as they form the basis of the Contract that will govern our dealings with you. They apply to the provision of the Maintenance Services to both Business Customers and Domestic Customers. Please read the definitions below carefully to identify on what basis you are contracting with us. If you are unsure then ask us. Some Conditions will apply just to Business Customers and some just to Domestic Customers and these are clearly marked as such. If a Condition is silent on this subject then it applies equally to both. The latest version of these Conditions may be obtained at any time by contacting Certas Energy (or by visiting and-conditions).

Please read Conditions 7 and 9 carefully as they set out provisions relating to your potential liability to us and our potential liability to you under each Contract. Condition 4 explains the Charges which you may have to pay.

How the Contract is made between us
2.1 These Conditions apply to all Contracts and set out the whole agreement between you and us to the exclusion of all other terms and conditions (provided always that, for Domestic Customers, this provision does not affect your legal rights in relation to the Maintenance Services and it is not intended to limit those rights in any way). Any terms or conditions which you put forward (whether endorsed on, delivered with or contained in your purchase order(s) or included in any other documents) do not form part of any Contract and any attempt by you to exclude, vary or limit any of these Conditions shall be void. You must ensure that you read and understand these Conditions because they will govern your dealings with us once a Contract is formed as set out below.

2.2 We intend to rely upon the terms set out in these Conditions. If you require any changes please make sure you ask for these to be put in writing before the Contract is formed. In that way we can seek to avoid any problems surrounding what we and you are each expected to do. Business Customers only: any
representation about the Maintenance Services shall have no effect and shall not form part of the Contract unless agreed in writing by us, acting through one of our authorised employees (which do not include any of our telephone sales staff).
2.3 If you place an order with us to receive the Maintenance Services then that order is an offer from you to us to enter into a Contract which we are free to either accept or reject at our discretion. A Contract is formed (and these Conditions become binding on you) when we either: (a) confirm to you (either orally or in writing) that we have accepted your order or (b) commence performance of the Maintenance Services, whichever is the earlier. The Contract is subject to us undertaking an inspection of your Boiler at our first visit and determining that it meets our minimum standards.

Information about your services
3.1 The description of the Maintenance Services shall be as set out in the Pack (and will vary depending on whether you have elected to take the Boiler Shield or Boiler Shield Plus service option). If you have any general comments or queries regarding the Maintenance Services then you must raise these issues when placing your order. Our sales personnel are not consultants and are not able to provide you with technical advice as to particular products or performance issues and so if you have any specific or technical queries then you should address them to us in writing (any response we might provide to such queries will be given only to the best of our knowledge and belief and (for Business Customers only) without any liability on our part). Business Customers only: all other descriptions, specifications and illustrations which we issue or which are contained in our brochures, website(s) or other materials are approximations and for information purposes only and you should not rely upon the same.
3.2 We may, at any time and without notice to you: (i) change any of the advertising or product information materials referred to in Condition 3.1; (ii) make changes to the scope of the Maintenance Services that we believe are necessary to ensure that they conform to any applicable safety or statutory requirements; and/ or (iii) make minor modifications to the scope of the Maintenance Services that we consider necessary
or desirable (and which should not have any material adverse effect on the provision of the Maintenance Services).

4 What you pay
4.1 Charges in respect of the Annual Service: Before you enter The Contract, we will inform you as to the price you will be charged for the first Annual Service based on the information which you have provided to us (and on the assumption that the Annual Service can be completed within one and half hours) for our Boiler Shield or Boiler Shield Plus Maintenance Services. If we find upon arrival at your Residence that any of the information you have provided is incorrect or incomplete then we reserve the right to either cancel the Contract or to revise the price accordingly – we will then inform you as to the new price and you may accept the revised price or cancel the Contract with immediate effect and without charge.
4.1.1 Over-Run Charge: If the Annual Service takes longer than one and a half hours to complete then in addition to the quoted charge there will, in respect of Boiler Shield customers and (in respect of the initial Annual Service only) Boiler Shield Plus customers, be an additional charge based on the time spent by us providing the required Maintenance Services (applying the quarter-hour charge out rate which will be advised to you at the time of the service and is also available on request).  This over-run charge will: (i) always apply in respect of Boiler Shield customers and (ii) apply, in respect of Boiler Shield Plus customers for the initial Annual Service only, (unless, for Boiler Shield Plus customers, the required additional work is of a type specified in your Pack as being excluded from the scope of our Maintenance Service plans in which case any such works (and related costs) would need to be separately agreed between us).

4.1.2. Our Rates: Copies of our latest price list setting out our Maintenance plan charges are available to you either by calling us or visiting our website at
4.1.3 Parts: Parts will be charged at cost plus a reasonable margin to cover our procurement costs and as advised to you prior to the relevant Part(s) being fitted.
For each subsequent Annual Service the price for our Boiler Shield and Boiler Shield Plus Maintenance Services (as appropriate) will be as is set out in the relevant appointment/renewal notice.
4.2 Charges in respect of the Emergency Repairs:
• For Boiler Shield Plus customers: included in the cost of the Maintenance Services (save that any Parts which are not listed in the Pack as being covered and which will be charged at cost plus a reasonable margin to cover our procurement costs and as advised to you prior to the relevant Part(s) being fitted plus any diagnostics or associated callout and labour). Boiler Shield Plus will include a first visit where, should any fault be diagnosed that is outside the scope of cover and subsequently requires repair, the required Part(s) and labour to rectify, whether this involves a return visit or not, is excluded from the plan; or
• Boiler Shield Plus customers only: Please note that if we are required to undertake any Emergency Repairs in respect of your Boiler due to any deliberate, negligent or accidental damage including oil run-out (save in the unlikely event such damage is caused by one of our engineers), then such repairs will not be covered by your Maintenance Service plan and you will be charged for the relevant repairs and Parts as if you were a Boiler Shield customer.
• For Boiler Shield customers: equal to the initial callout charge plus a charge based on the time spent undertaking the repairs together with the cost of any Parts (which will be charged at cost plus a reasonable margin to cover our procurement costs and as advised to you prior to the relevant Part(s) being fitted). If any subsequent visits are required in connection with the same emergency then those visits will be charged on a time and materials basis (excluding the initial callout charge). Charges in respect of the Emergency Repairs are determined by reference to our latest price list (which may be obtained by calling us – visit our website
for contact details at The costs which will be advised to you when you call to arrange an Emergency Repair.

4.3 VAT: All Charges in respect of the Maintenance Services are exclusive of VAT (if applicable). We will, however, provide you with a VAT inclusive figure when providing you with a quote for any goods or services and again when we issue an invoice to you.
4.4 Card Processing Charges: There are no card processing charges in respect of payments made via debit or credit cards.
4.5 Failed Appointment Charge: if we are unable to perform the Annual Service or any Emergency Repairs due to some default on your part (including, where we are unable to gain access to your residence on an agreed date) then we may, at our option, charge you the sum of £25 (the “Failed Appointment Charge”) this being a reasonable pre-estimate of the cost to us in seeking to perform the relevant services.

5 How you pay us
5.1 Payment: We will invoice you following the performance of the Annual Service in respect of the relevant Charges except in the case of Boiler Shield Plus customers where you will be invoiced by renewal notice prior to, rather than on completion, of the service. Unless otherwise notified to you, you will pay each of our invoices (in respect of the relevant Charges) within (for Business Customers only) 25 days or (for Domestic Customers only) 14 days of the date of the invoice being raised. However, we may require you to pay the Charges in advance at the time you place the relevant order.
5.2 In addition to the standard Charges referred to above, we will invoice you following the performance of any Emergency Repairs in respect of the relevant Charges. Such Charges shall be payable in accordance with the payment terms referred to in Condition 5.1.
5.3 We shall be deemed to have received payment under the Contract only on receipt of cash or cleared funds from you. All sums properly due and payable to us under a Contract shall become due immediately upon its termination.
5.4 Business Customers only: you shall make all payments due under the Contract in full without any deduction whether by way of set-off, counterclaim, discount, abatement or otherwise (except as may be required by court order).
5.5 Without limiting any other rights or remedies we may have, if you do not pay us on time, we may do all or any of the following:
(a) cancel or suspend the Contract (and any other Contracts we have with you) and/or any outstanding quotations;
(b) cancel any discount we previously offered to you under the Contract;
(c) without notice suspend or cancel performance of the Maintenance Services under the Contract until you pay the outstanding amounts in full; and/or
(d) charge interest on the outstanding amount, calculated on a daily basis from the due date for payment up to the date of actual payment. You must pay us this interest together with the overdue amount. For Business Customers the rate of interest shall be determined in accordance with the Late Payment of Commercial Debts (Interest) Act 1998. For Domestic Customers the rate shall be 4% above the base lending rate of Natwest Bank from time to time.

6 Our Maintenance Services for you
6.1 During the Term, we shall:
(a) perform the Annual Service (the scope of this Service shall be as specified in the Pack and will be the same regardless of whether you are receiving the Boiler Shield or Boiler Shield Plus Maintenance Services – if you have not received your Pack or if you require a further copy then please contact Certas Energy to request this); and
(b) upon request, use our reasonable endeavours to perform the required Emergency Repairs (in accordance with Condition 6.10),
in each case subject to, and in accordance with, the terms of the Contract.
6.2 We will only be obliged to provide the relevant Services during the Term if:
(a) your Boiler: (i) is a standard domestic boiler and it has not been modified (other than in accordance with the manufacturer’s instructions); (ii) has been correctly installed and maintained; (iii) complies with any and all relevant laws, regulations and standards; and (iv) is of a make and model which is covered by our Maintenance Services (as detailed in the Pack). Boilers more than 20 years of age are excluded from our Boiler Shield Plus product but we may agree to service such boilers under our Boiler Shield product subject to a satisfactory initial inspection and the provisos set out in this Condition 6.2;
(b) we are able to obtain any Parts required to perform the Services on reasonable commercial terms;
(c) it is safe and practicable for us to provide the Services at your Residence.  The decision to change or disturb a part during any visit is dependent upon the risk assessment carried out by our engineer on site. We reserve the right not to change any part, including filters, where a heightened risk is associated with its replacement, including unsafe or restricted access to
the boiler and its associated ancillary equipment.  This includes any part/pipework that is neither visible nor readily accessible to the engineer, buried or partially buried below ground or routed within the fabrication of the building, or installed in a position where it would not normally be found; and
(d) you have obtained any and all necessary consents and permissions required for us to provide the Services.
If we believe that you have failed to comply with any of the conditions set out above then we may terminate the Contract with immediate effect, without any charge to you or any liability on our part.
6.3 The Term of the Contract is 12 months and at the end of the initial Term it shall automatically renew (for Boiler Shield and Boiler Shield Plus customers respectively) for a further Term (and so on) unless or until the Contract is cancelled under Condition 6.6 or Condition 6.9.
6.4 During each Term we will issue an appointment notice to you in respect of your next Annual Service, which will include a proposed date for some time during our normal operating hours and in the following 2 to 6 weeks. This appointment notice will also include details as to our updated Charges for our Boiler Shield Maintenance Services.
6.5 If the proposed appointment date is not convenient then we ask that you call the contact number set out in the appointment notice to arrange an alternative date. If, however, you do not wish to receive our Boiler Shield or Boiler Shield Plus Maintenance Services at all then you may cancel the Contract by giving us
notice in accordance with clause 6.9 below – such termination will be without any charge to you (other than in respect of any Services performed prior to the date of termination) or any liability on our part.
6.6 We may terminate the Contract at any time with immediate effect if you breach any term of the Contract, or on one month’s notice without cause, without any charge to you or any liability on our part (other than to refund to you any Charges made in respect of Maintenance Services which have not been provided as at the date of termination).
6.7 If we have agreed a date with you on which we are to provide the Annual Service then:
(a) we will use our reasonable efforts to perform the relevant Maintenance Services on that date (and within the window of time notified to you (if any)); and
(b) you must ensure that our engineer can gain access to your Residence so as to perform the Maintenance Services. If you fail to do so and as a result we are unable to perform the relevant Services then we reserve the right to invoice you the Failed Appointment Charge.
6.8 All appointment dates and times are subject to availability and change although we will endeavour to notify you as early as possible if we are unable to make the relevant appointment date or time.
6.9 Your right to cancel: you may cancel the Contract at any time by contacting us using the cancellation form available on our website at, by calling 03457 620 620 or by email at

(b) If, however, the Contract is cancelled after the Annual Service has been performed (in accordance with the terms of the Contract) then no refund is due to you.
(c) If the Annual Service or any other services are to be performed within 14 days from the date the Contract is formed or an annual renewal date then we will not start any Services or the Annual

Service unless you clearly ask us to do so. You can ask by telephone or in writing. If you ask us to start any Services during the 14 days from the date that the Contract is formed or an annual renewal date then if you decide to cancel the Contract during those 14 days you must pay us for the Services provided up to the time you cancel. You must pay an amount which is in proportion to what we have done in comparison with the total amount due under the contract.
Where we repay you, we will use the same method of payment you used to pay (unless you agree otherwise); we will not charge you any fees to repay you. If we are allowed to charge you for any Services we have provided we may either take this out of what we repay you or ask you to pay the amount to us.
6.10 If you need emergency repair services from us:

(c) We will use our reasonable efforts to perform the necessary repairs to rectify any defect with your Boiler during our initial visit but if we are unable to do so, or we need to order Parts, then we will arrange for one or more follow-up visits as required. If you receive our Boiler Shield Maintenance Services then you will be charged a callout charge, together with a charge based on the time
and materials required, with any subsequent visits relating to the same callout being charged on a time and materials basis only (in accordance with our rates in effect as at the date of the relevant visit). If you receive our Boiler Shield Plus Maintenance Services then you will only be charged to the extent that any repair is outside the scope of the Boiler Shield Plus cover (such charges being calculated on the same basis as for Boiler Shield customers).
6.11 We shall ensure that all of the engineers we use are either employed by us or have been approved by us and that in each case they have the necessary qualifications to perform the Services in accordance with these Conditions. We can not be held responsible if a third party attends to the boiler and associated equipment without Certas Energy being given reasonable opportunity to call.
6.12 Any Part(s) which we supply and fit in connection with any Emergency Repair or Annual Service shall comply with the warranties set out in Condition 8. Please note that: (i) we will only fit Part(s) (and/or consumables) to your Boiler which we have supplied; and (ii) we do not supply Part(s) (and/or consumables) to be fitted by you or by any third party.

6.15 Boiler Shield and Boiler Shield Plus service plans exclude the cost of adding or replacement of inhibitor to a system irrespective of whether there is a requirement to drain the system to carry out other works.
6.16 Boiler Shield and Boiler Shield Plus service plans exclude the cost of callout and repairs as a basis of oil run-out.

8.1 Business Customers only: we warrant that the Maintenance Services will be performed with reasonable skill and care and that the Part(s) we fit will be free from material defect at the time of installation and unless otherwise agreed in writing we give no other warranty in respect of the Parts or Maintenance Services and all warranties, conditions and other terms implied by statute or common law (save for the condition implied

by section 12 of the Sale of Goods Act 1979) are, to the fullest extent permitted by law, excluded from the Contract.

8.5 Business Customers only: if we comply with our obligations under Condition 8.3 we shall have no further liability to you in respect of such Parts.
8.6 These Conditions shall apply equally to any replacement Parts we supply to you pursuant to Condition 8.3.
