Last updated: 25 June 2026

These Terms and Conditions apply to all quotations, equipment, installations, repairs, servicing, maintenance and other work supplied by KMS Electrical Service, trading as KMS Air Conditioning.

1. Business Details

KMS Air Conditioning is a trading name of KMS Electrical Service.

Registered address:
Kings Parade
Lower Coombe Street
Croydon
Surrey
CR0 1AA

Operational address:
Unit 11, Redlands Centre
Redlands
Coulsdon
CR5 2HT

In these Terms:

• “KMS”, “we”, “us” or “our” means KMS Electrical Service, trading as KMS Air Conditioning.

• “Customer”, “you” or “your” means the person or organisation purchasing goods or services from us.

• “Goods” means equipment, air-conditioning units, refrigeration equipment, components, parts and materials supplied by us.

• “Services” means installation, repair, servicing, maintenance, inspection, design, fault diagnosis or other work supplied by us.

• “Quotation” means our written description and price or estimated price for the agreed Goods and Services.

2. Application of These Terms

These Terms apply alongside any quotation, specification, maintenance agreement or other written document issued by KMS.

Where there is a conflict, the following order will apply:

1. Any written amendment specifically agreed between KMS and the Customer;

2. The accepted quotation, specification or service agreement;

3. These Terms and Conditions.

Nothing in these Terms affects any statutory rights available to a Customer under applicable UK consumer law.

3. Quotations and Site Surveys

Any prices displayed on the KMS website or in promotional materials are indicative “from” prices and do not constitute a final quotation.

Installation prices are subject to a site survey and may vary depending on:

• The type, specification and capacity of the system selected;

• The number and position of indoor and outdoor units;

• Pipework, drainage and electrical requirements;

• The proposed placement of the unit or units;

• Access, parking and working-height requirements;

• The layout, structure and condition of the property;

• The need for scaffolding, lifting equipment or specialist access;

• Planning, landlord, freeholder or building-management restrictions;

• Structural, decorative or electrical work;

• Any hidden or unforeseen conditions discovered during the work.

Unless otherwise stated, quotations remain valid for 90 days from the date of issue.

A quotation is based on the information and access available at the time it is prepared. KMS may revise or withdraw a quotation if information provided by the Customer is incomplete or inaccurate, or if previously hidden conditions become apparent.

4. Formation of the Contract

Submitting an enquiry through the KMS website, requesting a site visit or asking for a quotation does not create a contract.

A contract is formed when:

• The Customer accepts the written quotation;

• Any required deposit has been received or an alternative arrangement has been agreed; and

• KMS confirms the booking or proposed start date.

The accepted quotation will describe the agreed Goods and Services. Any additional or amended work must be agreed separately.

5. Prices

Prices will include or exclude VAT as stated in the quotation.

Unless specifically included in the quotation, prices do not include:

• Planning applications or building-control fees;

• Landlord, freeholder or managing-agent charges;

• Specialist structural work;

• Asbestos surveys or removal;

• Scaffolding, lifting equipment or specialist access;

• Upgrades to an inadequate electrical supply;

• Extensive plastering, decorating, tiling or making good;

• Work by independent third-party trades;

• Parking, congestion or access charges that could not reasonably be identified beforehand.

KMS will explain any additional charges and obtain the Customer’s approval before carrying out additional chargeable work, except where immediate action is reasonably necessary to make the property or equipment safe.

6. Deposits

A deposit of 30% of the quoted price will normally be required before equipment is ordered or an installation date is reserved.

An alternative deposit or payment arrangement may be agreed between KMS and the Customer. Any alternative arrangement must be confirmed in writing.

The deposit will be deducted from the final contract price.

Where equipment has been specially ordered, the Customer may be responsible for reasonable and unavoidable supplier, delivery, return or restocking costs if the contract is subsequently cancelled, subject to the Customer’s statutory rights.

7. Payment

Unless otherwise stated in the quotation:

• Deposits are payable when the quotation is accepted;

• Interim or staged payments may be agreed for larger projects;

• All invoices must be paid within 30 days of the invoice date;

• Repair, servicing and callout charges will be invoiced following attendance or completion of the relevant work.

The Customer must raise any genuine invoice query promptly and must pay all undisputed amounts by the due date.

For business customers, KMS reserves the right to claim statutory interest and reasonable debt-recovery costs on overdue commercial invoices where permitted by law.

KMS may suspend further work, servicing, warranty administration or the supply of Goods where an undisputed payment is overdue.

8. Equipment and Materials

Equipment will be selected according to the agreed specification, system design and availability.

Where a specified product becomes unavailable, KMS may propose an equivalent alternative. No material substitution will be made without the Customer’s approval.

Product images, brochures and manufacturer specifications are illustrative. Minor variations in appearance, dimensions, colour or finish may occur without affecting the intended performance of the equipment.

Specially ordered or customised equipment may require full or partial payment before it is ordered.

9. Installation Dates and Timescales

Any start date, installation date or completion date is an estimate unless KMS expressly confirms in writing that it is fixed.

KMS will not be responsible for delays caused by circumstances outside its reasonable control, including:

• Manufacturer, supplier or delivery delays;

• Equipment or material shortages;

• Severe weather;

• Engineer illness or unavailability;

• Unsafe working conditions;

• Restricted or unavailable access;

• Delays caused by the Customer or another contractor;

• Planning, landlord or building-management approval;

• Discovery of asbestos, unsafe electrics or structural problems;

• Utility failures, transport disruption or other emergencies.

KMS will inform the Customer of any significant delay and arrange a revised date as soon as reasonably possible.

10. Customer Responsibilities

The Customer must:

• Provide accurate information about the property and its intended use;

• Provide safe and reasonable access to the work area;

• Remove or adequately protect furniture, possessions and fragile items;

• Provide access to electricity, water and other required services;

• Inform KMS of known asbestos, structural defects, hidden services or hazardous materials;

• Keep children, pets, customers and unauthorised persons away from the work area;

• Obtain any required planning, landlord, freeholder, leaseholder or management-company permission;

• Ensure that the person accepting the quotation has authority to approve the work;

• Inform KMS of any site rules, parking restrictions or access requirements before attendance.

KMS may suspend or postpone work where access or working conditions are unsafe or unsuitable.

Additional visits, delays or costs caused by the Customer’s failure to meet these responsibilities may result in reasonable additional charges.

11. Electrical Supply and Other Trades

The Customer is responsible for ensuring that the property has an adequate and compliant electrical supply unless electrical work is specifically included within the quotation.

If additional electrical, structural, roofing, drainage or decorative work is required, KMS will explain this before proceeding wherever reasonably possible.

Work carried out by an independent third-party contractor will be subject to that contractor’s own terms and responsibility unless KMS has specifically contracted to provide and manage that work.

12. Performance of the Services

KMS will perform the Services with reasonable care and skill and in accordance with applicable professional and industry standards.

System performance may be affected by:

• The size, layout and insulation of the property;

• Windows, glazing and solar gain;

• External temperatures and weather conditions;

• Doors and windows being left open;

• Occupancy levels;

• Lighting, cooking appliances and heat-generating equipment;

• Correct operation of the system controls;

• Regular cleaning, servicing and maintenance.

No air-conditioning, heat-pump or refrigeration system can guarantee an exact temperature in every condition unless an exact performance requirement is expressly included in the written specification.

13. Changes and Additional Work

Any requested change to the agreed specification must be confirmed in writing.

A change may affect:

• The contract price;

• The equipment or materials required;

• The installation date;

• The completion date;

• The design or performance of the system.

KMS will provide an updated quotation or estimate before proceeding with material additional work.

Where an unforeseen issue is discovered, KMS will pause the affected part of the work, explain the issue and seek approval before carrying out additional chargeable work.

14. Repairs and Fault Diagnosis

Repair costs depend on the fault identified and may not be confirmed until the system has been inspected.

A diagnostic or callout charge may apply where:

• The fault cannot be repaired during the first visit;

• Replacement parts must be ordered;

• The equipment is beyond economical repair;

• The Customer decides not to proceed with the recommended repair;

• The reported fault is intermittent or cannot be reproduced;

• Access to the equipment is unavailable or unsuitable.

Where further work or replacement parts are required, KMS will provide an estimate for approval before continuing.

Fault diagnosis is based on the condition and symptoms of the system at the time of inspection. KMS cannot guarantee that an older or poorly maintained system will not develop separate or additional faults after a repair.

Where a system is no longer economical or safe to repair, KMS may recommend replacement rather than continued remedial work.

15. Emergency and Out-of-Hours Callouts

Emergency and out-of-hours attendance is subject to:

• Engineer availability;

• The Customer’s location;

• Safe access to the equipment;

• The nature of the reported fault;

• The availability of replacement parts.

References to emergency or 24-hour support do not guarantee immediate attendance or completion of a repair during the first visit.

Any applicable emergency, out-of-hours, travel or diagnostic charge will be explained before attendance wherever reasonably possible.

16. Servicing and Maintenance

A service is an inspection and maintenance visit intended to support the efficient and reliable operation of the equipment. It does not guarantee that the system will not subsequently develop a fault.

Depending on the equipment and agreed scope, servicing may include:

• Inspection and cleaning of accessible filters and components;

• Coil and drainage checks;

• System performance checks;

• Inspection of controls and electrical components;

• Identification of visible wear, damage or deterioration;

• Recommendations for repairs or further investigation.

The following may require a separate quotation:

• Replacement parts;

• Refrigerant recovery or recharge;

• Leak testing or leak repair;

• Deep or specialist cleaning;

• Access equipment;

• Repairs identified during servicing;

• Remedial electrical, structural or drainage work.

The Customer must follow any recommended maintenance schedule and keep user-accessible filters reasonably clean between professional services.

17. Property Protection and Making Good

KMS will take reasonable care when working at the Customer’s property.

Drilling, cutting and access work may be required to install or repair equipment. The quotation will state whether making good is included.

Unless specifically agreed, KMS is not responsible for final:

• Painting or decorating;

• Plastering;

• Tiling;

• Carpentry;

• Wallpaper repair;

• Matching of existing finishes.

KMS will not be responsible for damage resulting from:

• Defective, unstable or deteriorated surfaces;

• Hidden cables, pipes or structures that could not reasonably be identified;

• Incorrect or incomplete information supplied by the Customer;

• Existing leaks, defects or previous poor workmanship;

• The movement of furniture or possessions that the Customer was advised to remove;

• Unavoidable access required to complete the agreed work.

Any concern about damage directly caused by the work must be reported to KMS as soon as reasonably possible.

18. Ownership and Risk

Risk in Goods passes to the Customer when the Goods are delivered into the Customer’s physical possession or installed at the property, as applicable.

Ownership of Goods remains with KMS until all undisputed amounts relating to those Goods have been paid in full, to the extent that this is legally effective.

The Customer must take reasonable care of any unpaid equipment and must not sell or deliberately dispose of it without KMS’s written agreement.

19. Manufacturer Warranties

Manufacturer warranties are provided subject to the relevant manufacturer’s conditions, which may include:

• Registration of the equipment;

• Installation by a suitably qualified engineer;

• Regular servicing;

• Use of approved components;

• Correct operation of the equipment;

• Retention of service and maintenance records.

Manufacturer warranties are provided by the manufacturer and are separate from the Customer’s statutory rights.

KMS will provide reasonable assistance with an eligible manufacturer warranty claim but cannot guarantee that the manufacturer will approve it.

20. KMS Workmanship

KMS will complete installation, repair and maintenance work with reasonable care and skill.

Any concern regarding workmanship must be reported promptly so that KMS has a reasonable opportunity to inspect and, where appropriate, correct the work.

Workmanship cover does not apply to faults or damage caused by:

• Misuse, neglect or accidental damage;

• Failure to service or maintain the equipment;

• Blocked or unclean filters;

• Unauthorised alteration or repair;

• Electrical supply faults or power surges;

• External damage, flooding, pests or severe weather;

• Normal wear and tear;

• Failure to follow operating instructions;

• A separate fault in existing equipment or infrastructure.

Nothing in this section limits the Customer’s statutory rights.

21. Consumer Cancellation Rights

Where the Customer is a consumer and the contract is agreed online, by telephone or away from KMS’s business premises, the Customer may have a statutory right to cancel the contract.

Where applicable, the statutory cancellation period for a service contract will normally end 14 days after the contract is entered into.

If the Customer asks KMS to begin work during the cancellation period, the Customer must make an express request.

Where work begins at the Customer’s request and the Customer subsequently exercises a valid cancellation right, KMS may charge a proportionate amount for Services supplied before cancellation.

Where the Services have been fully performed during the cancellation period following the Customer’s express request and acknowledgement, the statutory right to cancel the completed Service may no longer apply.

Different rules may apply to Goods and equipment supplied as part of the contract. Any statutory rights will be considered according to the nature of the individual contract.

To exercise a cancellation right, the Customer must clearly inform KMS using the contact details in section 32.

22. Cancellation Outside Statutory Rights

Where no statutory cancellation right applies, the Customer may request cancellation by contacting KMS in writing.

KMS may retain or charge an amount representing reasonable and unavoidable losses caused directly by the cancellation, including:

• Work already completed;

• Engineer time already supplied;

• Non-refundable supplier charges;

• Specially ordered equipment;

• Delivery, collection or restocking costs;

• Other costs reasonably incurred in preparing to complete the contract.

KMS will take reasonable steps to reduce avoidable losses and will not impose a cancellation charge that is disproportionate to the loss incurred.

23. Cancellation or Suspension by KMS

KMS may suspend or cancel work where:

• An undisputed payment is overdue;

• The Customer fails to provide reasonable access;

• Working conditions are unsafe;

• Required permissions have not been obtained;

• The Customer or another person behaves abusively or threatens KMS personnel;

• Continuing the work would be unlawful or technically unsafe;

• Circumstances outside KMS’s reasonable control prevent completion.

The Customer remains responsible for Goods and Services reasonably supplied before suspension or cancellation.

24. Liability

Nothing in these Terms excludes or restricts liability where doing so would be unlawful, including liability for:

• Death or personal injury caused by negligence;

• Fraud or fraudulent misrepresentation;

• Breach of statutory consumer rights;

• Any other liability that cannot legally be excluded.

KMS will not be responsible for losses that were not reasonably foreseeable when the contract was formed.

KMS will not be responsible for loss caused by incorrect information, unsuitable access, pre-existing defects or failure by the Customer to follow operating or maintenance instructions.

For business customers only, KMS will not be liable for indirect or consequential loss, loss of profit, revenue, business, contracts, goodwill, anticipated savings or stock, except where such liability cannot lawfully be excluded.

Customers must notify KMS before entering the contract where interruption to heating, cooling or refrigeration could expose them to unusually high or specialised losses.

25. Complaints and Remedial Work

KMS aims to resolve concerns fairly and promptly.

A complaint should include:

• The Customer’s name and contact details;

• The property address;

• The quotation or invoice number;

• A clear description of the issue;

• Relevant photographs or supporting information.

The Customer must give KMS a reasonable opportunity to inspect and, where appropriate, correct the work before arranging remedial work through another contractor.

This does not prevent the Customer from taking urgent and reasonable action where necessary to protect people or property from immediate danger.

26. Personal Information

KMS may use personal information to:

• Respond to enquiries;

• Prepare quotations;

• Arrange site visits and appointments;

• Deliver Goods and Services;

• Process payments;

• Administer warranties;

• Maintain service records;

• Provide customer support;

• Meet legal and regulatory obligations.

Further information about the use of personal information is available in the KMS Privacy Policy.

27. Website Information

Information published on the KMS website is provided for general guidance.

Website prices, descriptions, images and availability may change without notice.

Website content does not replace a site survey, technical assessment, system design or written quotation.

KMS takes reasonable care to keep website information accurate but does not guarantee that every page will always be complete, current or free from errors.

28. Events Outside Our Control

KMS will not be responsible for failure or delay caused by circumstances outside its reasonable control.

These may include:

• Severe weather;

• Fire or flooding;

• Transport disruption;

• Manufacturer or supplier failure;

• Equipment or material shortages;

• Industrial action;

• Utility or communications failure;

• Government restrictions;

• Public emergencies;

• Acts or omissions by another contractor.

KMS will take reasonable steps to minimise disruption and resume the Services when it is reasonably possible to do so.

29. Third-Party Rights

No person other than KMS and the Customer has the right to enforce the contract unless expressly stated otherwise.

30. Severability and Waiver

If any provision of these Terms is found to be invalid or unenforceable, the remaining provisions will continue to apply.

A delay by KMS in enforcing a contractual right does not mean that the right has been waived.

Any amendment to the contract must be agreed in writing.

31. Governing Law and Jurisdiction

These Terms and any contract between KMS and the Customer are governed by the laws of England and Wales.

Consumers may bring proceedings in any court that has jurisdiction under applicable consumer law.

Business customers agree that the courts of England and Wales will have exclusive jurisdiction.
