HBXL Plans Service: Terms and Conditions

House Builder XL Limited (“HBXL”) agrees to provide the services (the “Services”) requested in the HBXL Plans Service Order Form (the “Order Form”) and confirmed in the HBXL Plans Service Confirmation Email (the “Confirmation Email”) subject to the following terms and conditions. You should carefully read this document as it contains the terms and conditions applicable to the provision of the Services and includes limitations of HBXL’s liability to you and others.

The Services

  1. HBXL warrants that it will carry out the Services:
    • using the reasonable care and skill to be expected of an ordinary, competent building contractor. You acknowledge that HBXL is not an architect or similarly qualified designer (and nor are its employees, agents and subcontractors) and does not hold itself out as such;
    • if stated in the Confirmation Email, so that the designs, drawings, plans and other documents (the “Deliverables”), when completed, are suitable for submission for planning and/or building regulations approval (but HBXL does not warrant that such approvals will be granted by the relevant statutory authorities);
    • using reasonable endeavours to provide the Services within any agreed time, but time shall not be of the essence in relation to the supply of the Services; and
    • in compliance with its obligations (if any) as a designer under the Construction (Design and Management) Regulations 2015 (or any re-enactment thereof) but, for the avoidance of doubt, you acknowledge that HBXL shall not be the “principal designer” for the purpose of those Regulations whether by carrying out the Services or otherwise.
  2. In carrying out the Services HBXL shall be entitled to rely upon all documents, measurements, drawings, plans and all other information provided by you (together, the “client-supplied information”) without any further checks, investigation or analysis and you warrant that all client-supplied information is true, accurate, up-to-date and free from discrepancies.
  3. If HBXL agrees, as part of the Services, to submit the Deliverables to any statutory authority (such as planning or building control) on your behalf, HBXL will pay the statutory fees, charges or other sums levied by such authorities for the submissions. If not itemised as part of HBXL’s fees, you will reimburse HBXL for such fees, charges or other sums within 7 days of a written request from HBXL.
  4. Subject to any rights in the client-supplied information, the copyright in the Deliverables shall remain vested in HBXL.
  5. Subject to payment of all of HBXL’s fees for the Services that are due and payable under this contract, HBXL will grant you an irrevocable, non-exclusive licence to use, copy and modify the Deliverables (including reproducing the designs contained in them) for all purposes in connection with the construction work contemplated therein, including:
    • submission to the planning and/or building control authorities;
    • further developing the Deliverables so that they are suitable for issue for construction of the works; and/or
    • the construction, sale, letting and/or repair of the works,

but HBXL shall not be liable for any use of the Deliverables (or the designs contained in them) if they have been modified or are used for any purpose other than that for which they were provided.

Limitations of liability

  1. Subject to clause 7, HBXL shall have no liability to you arising out of or in connection with the provision of the Services and the Deliverables (whether in contract, tort (including negligence), breach of statutory duty or otherwise):
    • for any loss of profit, loss of business, loss of rent or any other indirect or consequential loss; and
    • in respect of all other losses, in excess of £1,000,000 in aggregate for all claims.
  2. Nothing in this contract shall limit or exclude HBXL’s liability for losses arising out of:
    • death or personal injury caused by the negligence of HBXL (or its employees, agents or subcontractors); or
    • fraud or fraudulent misrepresentation.

Termination and force majeure

  1. You may terminate this contract by giving not less than 14 days’ written notice to HBXL. In the event of termination of this contract before the Services have been completed:
    • you shall be liable to pay HBXL for the time spent carrying out the Services up to the date of termination at the hourly rate as published in the HBXL Plans Service Price List (please see www.estimating-service.co.uk/pricing) as of the date of termination; and
    • following payment of our fees calculated on the basis set out at clause 8(a), HBXL will provide to you the Deliverables in whatever form they have reached as of time when the contract was terminated.
  2. For the purposes of this contract “Force Majeure Event” means an event beyond the reasonable control of HBXL including but not limited to strikes, lock-outs or other industrial disputes (whether involving the workforce of HBXL or any other party), failure of a utility service or transport network, act of God, war, riot, civil commotion, malicious damage, compliance with any law or governmental order, rule, regulation or direction, accident, breakdown of plant or machinery, fire, flood, storm or default of suppliers or subcontractors.
  3. HBXL shall have no liability for any losses caused or contributed to by any delay or failure to perform its obligations under this contract as a result of a Force Majeure Event.
  4. If one or more Force Majeure Events prevents HBXL from providing any of the Services for more than 3 consecutive weeks, either party shall, without limiting its other rights or remedies, have the right to terminate this contract immediately by giving written notice to the other.


  1. You agree to pay HBXL the full fee set out in the Confirmation Email for the Services before any work starts.

Variations to the Services

  1. If you wish to change your requirements in respect of the Services, or to have us perform further work following completion of the Services, and HBXL (in its absolute discretion) agrees to carry out such changed or additional work, you will be charged over and above our original agreed fee using the hourly rate as published in the HBXL Plans Service Price List (please see www.estimating-service.co.uk/pricing) as of the date of such agreement for that changed or additional work.
  2. HBXL will confirm the additional fee in writing before carrying out the additional or changed work. You agree to pay HBXL the additional fee in full before any further work is carried out by HBXL.

Assignment and subcontracting

  1. HBXL may at any time assign, transfer, charge, subcontract or deal in any other manner with all or any of its rights under this contract and may subcontract or delegate in any manner any or all of its obligations under this contract to any third party or agent.
  2. You may not assign, transfer, charge, subcontract or deal in any other manner with all or any of its rights or obligations under this contract without the written prior written consent of HBXL.

Notices or communications not sent by email shall be delivered to the other party personally or sent by prepaid first-class post, recorded delivery or by commercial courier, at its registered office (if a company) or (in any other case) its principal place of business, or sent by fax to the other party’s main fax number.
  3. Any notice or other communication shall be deemed to have been duly received if delivered personally, when left at the address referred to above or, if sent by pre-paid first-class post or recorded delivery, at 9.00am on the second business day after posting, or if delivered by commercial courier, on the date and at the time that the courier’s delivery receipt is signed, or if sent by fax, on the next business day after transmission.

  4. Clauses 17 to 19 shall not apply to the service of any proceedings or other documents in any legal action.


  1. A waiver of any right under this contract is only effective if it is in writing and shall not be deemed to be a waiver of any subsequent breach or default. No failure or delay by a party in exercising any right or remedy under the contract or by law shall constitute a waiver of that or any right or remedy, nor preclude or restrict its further exercise.  No single or partial exercise of such right or remedy shall preclude or restrict the further exercise of that or any other right or remedy.


  1. If a court or any other competent authority finds that any provision of this contract (or part of any provision) is invalid, illegal or unenforceable, that provision or part-provision shall, to the extent required, be deemed deleted, and the validity and enforceability of the other provisions of this contract shall not be affected.
  2. If any invalid, unenforceable or illegal provision of this contract would be valid, enforceable and legal if some part of it were deleted, the provision shall apply with the minimum modification necessary to make it legal, valid and enforceable.

No partnership

  1. Nothing in the contract is intended to, or shall be deemed to, constitute a partnership or joint venture of any kind between any of the parties, nor constitute any party the agent of another party for any purpose. No party shall have authority to act as agent for, or to bind, the other party in any way.
