1. Preparing your property for our technicians

Prior to the first day of our works, we expect that you will have made the necessary arrangements to prepare your property for our technicians. The nature of our works is considerably physical, necessitates the use of heavy machinery and the bringing onto site of heavy materials.  Consequently, in instructing us, you agree that you will clear the working area of all fixtures, fittings and items to which any damage is possible. Further, you agree that if such items are left in the working and access areas, we will not be liable for any damage that occurs to these items. The areas in which work will be carried out are indicated in our Floor Plan; these areas and the access routes to them need to be completely clear before we arrive on site.  In particular, the following items must be removed from the working area unless otherwise agreed in writing:

a) All furniture;

b) Carpets;

c) Floor coverings (including laminate flooring);

d) Kitchen appliances (if present in the working area);

e) Radiators

f) Personal effects;

g) Decorative fire surrounds and hearths, including those made of marble;

h) Light switches, fixtures, shades, chandeliers, lamps or similar;

i) Hanging decorations such as paintings, frames, mirrors, tapestries or similar; and

j) Any other item of furniture or appliance that might cause an obstruction or may otherwise be damaged as a result of our works.

Any ceramic floor tiles, laminate flooring or similar that you do not remove, must be covered with sheets of hardboard to avoid damage.  Please note that we cannot reimburse you for any items which you do not remove from the working area and which later become damaged as a result of the works. The removal of fixtures such as kitchen units, radiators, pipework and cables will normally be necessary before our works are carried out.  Unless we have specified otherwise in our report, you should arrange for the removal of these items prior to our works commencing.  Normally, the requirement for the removal of such items is mentioned in our report, but it can safely be assumed that any section of wall on which we need to carry out work will need to be stripped of its fixtures before work commences.  If you are unsure about this, please contact us in good time.

2. Gas, electricity and water

In carrying out our initial survey, we did not assess the condition of any gas, electrical or water services either inside or outside of the property, as we are not qualified to do so. In providing our quotation, we assumed that the service pipes and cables to and throughout the property accord with current building standards; our quotation does not include any costs relating to these services, unless otherwise specified.

The nature of our works is considerably physical, necessitates the use of heavy machinery and the bringing onto site of heavy materials.  During the course of such works, damage to cables, pipes, installations and similar can occur.  In accepting these Terms, you agree that the cost of any repair or replacement of pipes, cables, installations or similar which become damaged as part of our works will be charged to you.  Further, where pipes, cables, installations or similar do not accord with current building standards or are otherwise defective, any and all costs of repair, replacement or upgrading these items will be paid for by you.

Where we mention or quote for any amendment, improvement or installation which uses the gas, electricity or water services in the property, this is given on the assumption that all services accord with current building standards.  All such matters are subject to an inspection by our qualified contractor(s) and where the current services do not accord with current building standards, the additional cost of upgrading those services will be paid for by you.

Where pipes and cables for services are not removed from any areas requiring treatments or works, we will not (unless otherwise agreed in writing) cover such works with any guarantee that we may issue.

3. Timescales

In accepting these Terms, you agree that any mention that we or our staff make of the time it might or will take to complete the contracted work should be regarded as a helpful indication and does not constitute (unless otherwise agreed in writing) a promise or guarantee that a project will be completed by a certain date or time.  Further, you agree that we will not be liable for any loss (financial or otherwise) incurred by you or any other person as a result of our works taking longer or less time than that suggested.

Where any indication or suggestion of timescale is given by us or our staff, you agree that no reduction in the final bill will be made if the work is completed sooner or later than that indication.

4. Quotation

Our quotations are:

a) Valid for three months from the date of its issue;

b) Based on the assumption that the thickness of wall plasters requiring removal does not exceed 20mm, which is the standard depth in most homes.  The thickness of wall plasters will be subject to measurement on site and, where the thickness of said plasters exceeds this amount, we reserve the right to increase our quotation to reflect the additional work required to remove and reinstate them;

c) Based on the assumption that a 110v/240v power supply and clean water supply will be available to us on site throughout our works;

d) Limited to the work that we have explicitly quoted for.  During our works, where we notice that additional work is required, we will provide an additional report and quotation for your approval.

e) Prepared for the benefit of you to understand the minimum cost that you will be liable to pay on the completion of the project. Where less work than that referred to in the quotation is required, a reduction to the figure in the quotation may be made, but at our sole discretion and any reduction will be calculated on a time and material cost basis only.

f) Prepared in order for you to decide whether to instruct us to carry out works. In instructing us to carry out any works, you agree that you will be liable to pay the total amount listed in the quotation. Further, you agree that a full or more comprehensive breakdown of costs will not be provided, unless otherwise agreed by us.

5. Construction Design and Management Regulations 2015

In accordance with the Construction Design and Management regulations 2015, we must provide our technicians with access to a toilet and washing facilities. Unless otherwise instructed by you, we have assumed that staff will have access to use your facilities during the progress of the works. This avoids the necessity for alternative arrangements to be made, which may not be ideal on a domestic contract. Our technicians are responsible, trustworthy and will treat your facilities with the utmost respect as they would treat their own. However, if you are unable to provide access to your facilities, please let us know in advance and we will try to make other arrangements. However, if this cannot be done we may need to modify the quotation accordingly, to include the cost of a welfare unit/Portaloo. Contrary to the above, you must inform us when placing your order for work that these facilities will not be available.

6. Party Wall etc Act 1996 and damage to adjacent properties

Please note that where any of our recommended works are to walls which fall within the definition of a party wall as per the Party Wall etc. Act 1996, you are required to obtain the consent of your neighbours prior to the start of any works.  In addition, if your property is a listed building, you should obtain the necessary permissions before any works are carried out. If no notice in writing is provided to the contrary, we will assume that all necessary steps have been taken by you to comply with the law.

As part of our works, we commonly use heavy machinery to remove wall plaster from the walls.  These tools cause vibration, which can lead to hairline cracks, small holes and/or damage on the reverse sides of each wall; notably on the side of a neighbouring wall. Unfortunately, such damage is an unavoidable (but thankfully, rare) occurrence of using any drills or machinery on such walls and, as such, any liability for repairing damage to the neighbouring property will rest with you. Of course, we are happy to assist with repairs where we can and we understand that such incidences can cause tension between neighbours, but we reserve the right to levy a reasonable charge, should additional work be required to carry out those repairs.

7. Local Authority requirements

Where planning permission or any other permission is required before any of our works commence, it is your responsibility to obtain this.  It is not our responsibility to draw your attention to the requirement for such permissions and you should seek specialist legal advice in this respect, where required. Where any loss (financial or otherwise) arises to you or any other party as a result of the breach of or failure to obtain suitable permission to carry out our works, you agree that we will not be liable for said losses and that you will indemnify us to this effect.

8. Asbestos and other substances harmful to health

Where we suspect that a building material containing asbestos or similar product is present in the property, a separate, qualified contractor must carry out tests on these materials prior to our arrival on site to ensure that they are safe to be disturbed. If we discover any materials which may contain asbestos during our works which was hidden prior to undertaking them, we may need to evacuate the site immediately to ensure the safety of our operatives.  In either case, we can arrange for the testing and removal of asbestos and other harmful products; this will incur an additional fee.  It is a legal requirement for us to ensure that our Technicians do not come into contact with harmful materials; in cases where we conduct an asbestos test or similar and no harmful products are found, the cost of the test is still chargeable to you.

9. Dust, dirt, discolouration and disturbance

An inevitable and unavoidable consequence of any of our work is the creation of a considerable amount of dust and dirt.  This is particularly the case where wall plaster is removed and applied, and where the drilling of internal walls takes place.  Though our Technicians will endeavour to carry out their work in as reasonably clean a manner as possible, it is inevitable that dirt and dust will still be present after the completion of the works.  Where such works are carried out, it should be noted that dirt and dust can continue to settle for several days following the works, necessitating repeat cleaning throughout that time.  We cannot be responsible for anything more than the reasonable tidying of the working area following the completion of our works.  For the avoidance of doubt, our responsibility will not extend to the cleaning of units, raised surfaces or any other item or surface in or close to the working areas which had not been covered by you in advance of the works.  Any item or surface which had been covered by you and which also becomes affected by dust and dirt as a result of the works will similarly not be our responsibility to clean. We can assist with the necessary cleaning following the completion of our works and can instruct a suitably qualified and insured cleaning service to carry out a deep clean.  This will be charged at an extra cost. Whilst all reasonable care will be taken, there is a slight risk of the discolouration to ceilings etc. following timber treatments and no responsibility can be accepted should this occur. The works may be unavoidably noisy and our quotation assumes that the work will be carried out in normal working hours, with no undue restrictions. Where our works involve the use of drilling machines which can cause vibration, we strongly suggest you remove any objects from the walls which may be loosened or damaged by such vibrations. It is also possible that existing plasterwork or render may be loosened if it is not well bonded to the brickwork. We accept no responsibility for any claim for such damage due to these vibrations and we suggest that you notify the owners of any adjacent properties of our impending works.

10. Decoration

Wall plaster should be allowed to dry out before any permanent decoration is applied. We recommend that a minimum drying time of 6-8 months is allowed however, one coat of matt emulsion can be applied to each wall as soon as it appears visibly dry.

11. Drilling into walls following our treatments

In cases where we have applied a cementitious tanking system or damp proofing membrane to a wall or floor, drilling into this may lead to the breach of the system and allow damp to affect the wall once again.  Consequently, works which require the removal of wall plaster or drilling (such as electrical works, for example) should be carried out before our works.

12. Payment and additional charges

Invoices will normally be rendered upon completion of the work and are payable either immediately or within 14 days of the date of issue of the invoice. Where we deem it suitable, we will issue interim invoices, which are similarly payable immediately or within 14 days of the date of the invoice.

When applicable, our Guarantee document will only be issued following full settlement of the account to which it relates.  Non, part or late payment voids the terms of our Guarantee.  Any other formal documents such as surveys, results, certificates, receipts or otherwise will only be disclosed to the client on full payment of the final invoice.

Any additional banking charges incurred by us due to dishonoured cheques will be chargeable to the client, together with an administration cost.

13. Cancellation

A penalty will be charged to the client if a job has been booked to commence and is cancelled in 14 or fewer days of the commencement date- this is not disapplied if the project is booked to commence in 14 or fewer days from the booking date; cancellation on such projects will still incur this charge.  The charge for cancelling a project in 14 or fewer days from the commencement date is 33% of the total contract value or £500.00 plus VAT, whichever is higher.

14. Postponement

Where you choose or cause the start date of your project to be postponed and this is only brought to our attention in 14 or fewer days before the date that your project will start, a charge will be incurred.  The charge for postponement is £150.00 plus VAT for every full half day that the project is postponed to a maximum charge of £1,500.00 plus VAT.

15. Delay or interruption

Where your actions or omissions cause a delay or interruption to our work, you agree that we are entitled to charge for our reasonable costs which are incurred as a result of that delay or interruption and that this charge will be no less than £200.00 plus VAT.

16. Arrangements for late or non-payment

Where full payment is not made on or before the expiry of the period stipulated in section 10 above, the terms in this section will apply.  Unless agreed otherwise in writing, a late payment charge will be added to our final invoice following the expiry of the payment deadline; this will be calculated accordingly:

Invoice value (before VAT)Late payment fee (before VAT)
£0.00 – £1,000.00£250.00
£1,001.00 – £5,000.00£450.00
£5,001.00 – £10,000.00£750.00
£10,001.00+10% of the full contract value

In addition to the late payment fee, we will charge interest, to be calculated daily at a rate of 8% Per Annum plus VAT above the Bank of England’s base rate for every full day following the expiry of the payment period that the invoice is not settled.  Where payment is not received and we receive no confirmation from you that you intend to settle the bill, we will take steps to instruct the services of a reputable debt collection agency to recover our costs, plus any of the aforementioned fees and interest charges from you.  Further, we reserve the right to recover from you any agency fees, including any court or legal fees associated with the recovery.

17. Financing agreements (where offered by Allerton Remedial Treatments and not one of our finance partners)

All financing agreements are offered at our sole discretion and are subject to a successful application.  An application for financing should be made at the point of placing an order for works; if an application is not made at this time, your application may be refused for this reason alone.  We offer 5 or 10 month payment options and require a 15% deposit on completion of the works in all cases.  We offer 5 months 0% finance on projects of £3,000.00 (inclusive of VAT) or more and 10 months 0% finance on projects over £5,000.00 (inclusive of VAT).  Due to current legislation, we are not able to offer 0% finance which exceeds a value of £25,000.00 (inlclusive of VAT) and nor are we able to offer a finance term of longer than 10 months. Examples of typical finance agreements are set out below:

18.e Other terms

Rejection of an application for finance does not excuse you from our Cancellation, Postponement, Delay or Interruption conditions set out in these Terms of Business.

20. Guarantee

Where we have offered a Guarantee in our Survey Report, this is our Standard 20-year written Guarantee.  Since 1983 we have issued guarantees with much of our work, but we are proud to report that more than 99% of our customers have never needed to use them.  For further peace of mind, in addition to our Standard Guarantee we can offer Guaranteed Protection Insurance (“GPI”), at a further cost.  Under GPI, the Property Care Association will instruct one of its members to uphold the Guarantee if, during the first 10 years of our Guarantee, we cannot fulfil our obligations under it for any reason.  For further information about GPI, please contact us.

Our guarantees:

a) Do not necessarily apply to all of the work that we carry out.

b) Will only be issued following the account to which they relate being settled in full.

c) Are only transferable with our consent.

d) May be cancelled or withheld should the account to which they relate fall into arrears or default at any time.

21. Cases where the need for additional work is discovered

In the unfortunate event that, during our works, we discover that additional work is necessary, we will endeavour to consult you about the additional time and cost implications before proceeding. This is sometimes not possible if you are not contactable when we are due to proceed with the works. A non-exhaustive series of examples of the circumstances in which this can arise are provided below:

a) If we are removing wall plasters as part of our works, we will need to ensure that the surface beneath the plaster is suitable for replastering.  If it is the case that the surface beneath the old plaster is coated with gloss paint, this must be removed before new plaster is applied.  We can arrange to do this for an additional cost;

b) Where moisture has entered into a building due to rising or penetrating damp, it is possible that fungal decay, which would weaken structural timbers, may be present and hidden behind wall plaster and skirting boards.

c) Where plaster is thicker than anticipated, we have to then dispose of additional materials and increase the amount of materials used for the work as well as additional labour. In this instance it is not practical for us to halt working to inform the client of any additional charges, we will of course endeavour to do this however if it is not possible we will proceed as normal.

d) Solid floor removals can sometimes be hindered if they are reinforced with steel, our quotation to remove a solid floor is always based upon the assumption that no steel is submerged in the floor. If this is discovered once work commences we will have to adjust our quotation to accommodate the extra labour.

e) Where the thickness of any wall plaster which we have quoted to remove exceeds a depth of 20mm, an additional charge for the additional labour time taken to remove the plaster will be levied.

In any event and whether we consult you or not, in accepting these terms, you authorise us to carry out additional work to the value of £200.00 plus VAT or 10% of the total contract value plus VAT (whichever is higher) where the need for any additional work is discovered.

22. Where we remove fixtures on your behalf

As part of our works and quotation, we may have included a charge to remove and/or reattach fixtures and fittings as part of the works, such as:

a) Radiators or other heating units;

b) Pipework for water or gas;

c) Fixed items of furniture; and

d) Kitchen units or appliances.

Where we remove and/or reinstate these items, you accept that some reasonable damage may occur during that process. For instance, where radiators are removed, the radiator valves have often deteriorated and, when reattached, may leak slightly; new valves can be fitted at additional costs. Where kitchen units or other units are removed, depending on how they were fitted, it may not be possible to remove them without breaking parts; this is especially the case where such units have become damp.

23. Snagging

In the unlikely event that we have to return to a job to carry out additional work, following completion of the project and the issuing of your invoice, the following terms will apply:

a) Only one snagging list will be accepted from you and one visit to rectify the list will be arranged, we will not accept multiple lists, given at different times.

b) Even in the event that snagging is required, 90% of the total invoice is still due by the due date (if an invoice has been issued). If a 90% payment is not received by the invoice due date, the late payment conditions of these Terms of Business will apply.

c) Following completion of the snagging list, the remainder of the invoice is due in full within 3 working days of our departure from site. If payment is not received within this time, the late payment conditions of these Terms of Business will apply.

24. Changes to the original work design

In the event that, during our works, our technicians determine that a different system than the one originally proposed will benefit the property and provide a more effective solution to the identified defects, this will be changed without further notice to you. Any changes in accordance with this paragraph will not be subject to a reduction in the price of our works, though any increase in price will be reported to you before the works are carried out. Of course, any changes to the system which will result in a noticeable difference to the internal decoration of the property will be raised with you first to ensure that you are content with the new design.

25.Customers domiciled outside of the United Kingdom

In the case of clients who fall within this category, the Company reserves the right to require payment before the completion of any works.

26. Timber flooring

Where we install or replace timber flooring such as joists or floorboards, these have a tendency to expand, contract and settle depending on their daily usage and what climate they sit in; this can lead to occasional creaking. In such cases, creaking is not uncommon and, in accepting our terms, you agree that we are not responsible, if this occurs.

27. Itemisation of quotations, estimates or invoices

You agree that we are not obliged to provide an itemised quotation, estimate or invoice to you and that the provision of the same is purely at our discretion. Further, where we provide an itemised quotation or estimate, prices are given on the assumption that all of the proposed works are to be carried out and may be subject to revision if only part of the proposal is accepted.

28. Complaints

Where we cannot resolve any complaints using our own complaints procedure, as a Which? Trusted trader we use the Dispute Resolution Ombudsman. If, after following our complaints procedure, you wish to refer your complaint to the Ombudsman Service, you may contact them on 0333 241 3209 or via the Ombudsman’s website:
