Terms and Conditions / FAQs
By accepting the quotation we have provided, you acknowledge and agree to be bound by our full terms and conditions. These terms and conditions govern the contractual relationship between you and our company, encompassing all services, transactions, and interactions. Acceptance of the quotation implies that you have read, understood, and agreed to all stipulations, including payment terms, service delivery, and any other obligations outlined within our full terms and conditions document. It is important to review these terms thoroughly as they detail your rights, responsibilities, and the scope of our services.
All payments are required in full upon satisfactory installation, unless otherwise agreed in writing prior to the commencement of works.
Payments can be made by bank transfer, card payment, or cash. However, for all amounts exceeding £2,000, payment must be made via bank transfer only, due to banking limitations and fraud prevention protocols.
An invoice will be issued immediately following completion of the installation. Full payment is due within 48 hours of this invoice being issued. Failure to settle the outstanding balance within this 48-hour window will result in:
• The application of late payment interest, calculated daily at the Bank of England base rate, currently 2.25%, in line with the Late Payment of Commercial Debts (Interest) Act 1998.
• Suspension of any remaining or future services (including follow-up works, remedial visits, or warranty-related inspections).
• Your account being referred to a third-party debt collection agency. This may incur additional recovery fees and could have an adverse impact on your credit rating.
Please be aware that all legal and administrative costs incurred in the recovery of overdue payments will be chargeable in full to the customer.
We strongly recommend settling all invoices promptly to avoid any unnecessary charges or service disruptions.
If you believe there is a discrepancy or concern with your invoice, it must be raised in writing within 24 hours of receipt.
To secure your installation slot and allow us to proceed with ordering bespoke materials, a mandatory deposit is required for all projects exceeding £1,000.
• Deposit Amount: A deposit of between 35% and 50% of the total project cost is required, depending on the size and complexity of the work. The exact percentage will be confirmed and agreed in writing prior to any order being placed.
• Staged Payments: For larger or multi-phase projects, Calibur may request a staggered payment schedule (e.g. deposit, interim payment, and final balance) to reflect progress and procurement of materials. This will be clearly outlined and agreed in advance.
• Accepted Payment Methods: Deposits of up to £500 may be paid via credit card for added consumer protection. All larger payments must be made via bank transfer to the official Calibur Ltd business account.
• Third Party Payments: For legal and security reasons, third party payments are not accepted. All payments must be made by the named customer or the legal property owner.
• Non-Payment: Projects will not proceed until the agreed deposit is received in full. Failure to make a deposit within the specified timeframe may result in delays or cancellation of your booking.
If you pay by credit card, your payment should be protected under Section 75 of The Consumer Credit Act. If you choose not to pay by credit card, it may not be protected. Credit Card payments up to £500, any further balances must be bank transferred.
Full payment is required within 48 hours of the invoice being issued, unless otherwise agreed in writing. We ask all customers to settle promptly to avoid disruption or additional charges.
• Statutory Interest Charges: Overdue payments will incur statutory interest on the total invoice amount, calculated at the Bank of England base rate + 8%, in line with the Late Payment of Commercial Debts (Interest) Act 1998. For reference, the current base rate is 2.25%, meaning a total charge of 10.25% APR may apply to overdue balances.
• Late Fee Penalties: In addition to interest, fixed late fee penalties may be charged:
• £50 initial charge for non-payment beyond 48 hours
• £10 per day for each additional day the balance remains outstanding
• Service Suspension: If payment is not received within 7 days, all remaining
services and remedial works will be suspended without notice, and future bookings or warranty claims may be affected.
• Debt Collection: Accounts overdue by more than 7 days may be passed to a third-party debt collection agency. All recovery costs, including agency fees, legal expenses, and court costs, will be added to the debt and pursued in full.
• Third Party Payments: For legal and security reasons, third-party payments are not accepted. All payments must be made by the named customer or legal property owner.
All materials, products, and fittings supplied and installed by Calibur Glass & Glazing Ltd — including but not limited to framework, glazing, hardware, fixings, and accessories — remain the sole property of Calibur Glass & Glazing Ltd until full and cleared payment has been received for the entire contract value.
• Retention of Title: Legal and beneficial ownership of all supplied goods does not transfer to the customer until all outstanding balances, including any applicable interest, late fees, or collection costs, have been paid in full.
• Right to Recover Goods: In cases of non-payment or breach of contract, Calibur Glass & Glazing Ltd reserves the right to enter the property without prior notice and remove any unpaid-for goods. This includes items already installed, subject to compliance with relevant laws and access permissions.
• Damage or Loss: Until ownership transfers, the customer is responsible for the care and safeguarding of all materials on site. Any loss, theft, or damage (whether accidental or intentional) during this period may still be charged to the customer.
• Resale or Modification: Customers are not permitted to sell, alter, or dispose of any products or materials supplied by Calibur Glass & Glazing Ltd until full payment has been made and legal ownership has transferred.

Blinds & Window Warranty Limitations
Please note that the installation of blinds directly onto our window or door products can affect the validity of your warranty. The following conditions apply:
Screw-Fixed Blind Clips
If blind clips or brackets are screwed into the window or door frame, sash, or glazing beads, this constitutes a physical alteration of the product. As such:
• Any warranty on the affected window or door will be void.
• We will not accept liability for damage or performance issues resulting from such fixings.
• Any required repairs or replacements caused by screw-fixings into the product will be fully chargeable to the customer.
Push-In Blind Clips (Tension-Fit Behind Beads)
If blind clips are pushed or wedged behind the glazing beads, sitting against the sealed glass units, this also carries risk. In these cases:
• We will not accept responsibility for any cracked, shattered, or otherwise damaged glazing that may occur during or after the installation of these blind types.
• If glass breakage occurs where blind clips have been installed in this manner, all remedial work (including sealed unit replacements) will be chargeable in full.
General Advice
If you intend to fit blinds to our products, we strongly recommend using non-invasive methods such as magnetic, adhesive, or tension-fit systems that do not pierce or interfere with the frame, sash, or beadwork. If you are unsure, please contact us prior to installation.
Conservatory surveys conducted by Calibur Glass & Glazing are subject to an hourly charge. This fee covers the time, expertise, and resources required to carry out an accurate and comprehensive assessment of the proposed works.
Should the customer proceed with the full conservatory installation project as quoted, the total cost of the survey will be deducted from the final project invoice. If the project does not go ahead for any reason, the survey fee remains payable in full and is non-refundable.
By agreeing to a conservatory survey, the customer acknowledges and accepts these terms and agrees to pay the applicable fee as invoiced. Calibur Glass & Glazing reserves the right to revise survey charges with prior notice and to withhold survey results or drawings until payment has been received in full.
Brickwork / render / roughcasting
All due care and attention will be taken in the installation process to preserve the condition of the building facade. If the facade is dated, broken, or worn and is suspected to be deteriorating or may break away during the installation process, we will advise on the day to the customer. It is the customers responsibility to remedy any such issues or repair works which are not directly caused by Calibur installation.
Alarm cables / telephone cables / misc. cables
As part of our commitment to providing excellent service, we take all necessary precautions to ensure that the cables entering your property remain intact and undisturbed during our work. This includes cables for your alarm system, telephone lines, internet, and other utilities.
Here’s what you can expect from us:
Identification and Protection: We will identify and clearly mark the location of all cables entering your property.
Careful Handling: Our team will handle all cables with care and take measures to protect them from damage.
Inspection: We will inspect the cables before and after our work to ensure they are in good condition.
While we will take all due care and attention, it is important to note that any repairs or maintenance required for these cables, especially for alarm or telephone systems, are the customer’s responsibility. Should any issues arise, we recommend contacting your respective service providers to arrange for repairs.
All composite doors supplied and installed by Calibur Glass & Glazing Ltd are fitted in accordance with industry best practices and the NHBC Standards (Chapter 9.1 – Finishes) to ensure quality, performance, and compliance.
We adhere to the following NHBC-aligned tolerances:
Opening & Frame Tolerances
• Level of heads and sills:
±5 mm for openings up to 1.5 m wide
±8 mm for openings over 1.5 m wide
• Plumb of reveals:
±5 mm for reveals up to 1.5 m high
±8 mm for reveals over 1.5 m high
• Flatness of sills or boards: ±3 mm per metre
• Square reveals (≤250 mm depth): ±5 mm
Door Frame Alignment
• Frame plumb:
Maximum deviation of ±8 mm over the full height of the door
• Door leaf distortion:
Maximum 5 mm vertically and 3 mm horizontally
Clearances & Gaps
• Gap between door and frame (top, sides, and meeting stile): Maximum 4 mm
• Gap beneath the door to finished floor level:
Standard clearance is 10–22 mm, allowing for floor finishes. Where a floor finish is present, a typical clearance of approximately 10 mm is expected.
Notes
These tolerances are important to ensure:
• Smooth and consistent door operation
• Effective weather and draught sealing
• Long-term durability and security performance
• Full compliance with NHBC warranty expectations
All installations are completed within these tolerances unless otherwise agreed in writing, or where site-specific conditions (such as structural irregularities or existing building movement) limit adjustment.
On receipt of your complaint the business aims to respond within 5-days.
The business will arrange a convenient date to come and view and/or remedy the situation within 28-days.
In the unlikely event the business is unable to resolve your complaint having exhausted the business complaints procedure, it may be necessary to use another complaint service. Where the business cannot resolve the complaint to your satisfaction and/or agree to the final resolution requests confirmed to us; and both parties agree a ‘deadlock’ has been reached, you can then escalate your complaint.
The business has access to an Alternative Dispute Resolution (ADR) service for our domestic installation, service, repair and maintenance contracts as part of the Which? Trusted Traders Endorsement. If you choose to, you can refer your complaint to Which? Trusted Traders’ Alternative Dispute Resolution. You will need to contact Which? Trusted Traders on 02922 670 040 who can explain if you are eligible to use their Alternative Dispute Resolution.
Liability for Glass Breakage Post-Installation
At Calibur, we take great care to ensure that all glazing and window installations are completed to the highest standards of workmanship and quality. However, once the installation process is complete and the work is signed off, the following conditions shall apply regarding glass breakage:
Post-Installation Responsibility: Upon successful completion of the installation and handover of the product, Calibur shall no longer be responsible or liable for any glass breakages, cracks, or damages that occur. This includes, but is not limited to, breakages caused by:
External impacts (e.g., accidental damage, vandalism, or weather conditions such as hail).
Movement of the building structure or foundations
Improper use or misuse by the customer or third parties
Any modifications, repairs, or alterations made to the product by parties other than Calibur.
Inspection and Acceptance: It is the customer’s responsibility to inspect the glazing and windows immediately upon installation. Any defects, damages, or concerns regarding the glass must be reported to Calibur within 24-hours of installation. Failure to do so will be deemed as the customer's full acceptance of the condition of the installation.
Warranties Exclusion: While Calibur provides a warranty for the installation workmanship, this warranty expressly excludes glass breakage after installation, except in cases where breakage is proven to result from defective materials or improper installation practices by Calibur.
Glass Characteristics: Customers acknowledge that certain glass products may have inherent characteristics, such as small bubbles, slight colour variations, or minor distortions, which are standard and do not constitute defects.
No Liability for Third-Party Actions: Calibur will not be held responsible for any damage or breakage resulting from third-party actions, including contractors, maintenance personnel, or any other parties not directly associated with Calibur.
By agreeing to these terms and conditions, the customer acknowledges and accepts full responsibility for the protection and care of the glass after installation is completed.
