Terms & Conditions

Plain-English terms for our plumbing, heating and gas work

These terms and conditions apply to plumbing, heating and gas work carried out by Plumbline MK ("we", "us", "our") for you, the customer ("you", "your"). By asking us to quote, booking a visit or accepting a quotation, you agree to them. They are written to be read, not to catch anyone out: if anything is unclear, ask us before the work starts.

1. The agreement

1.1 Acceptance

These terms apply to every job we do, including boiler installation, repair and servicing, gas safety certificates, emergency call-outs, plumbing and heating work. They apply whether you book by phone, WhatsApp, email or through this website.

1.2 What forms the contract

The contract is made up of these terms and the written quotation or confirmation we give you for the job. If the two disagree, the quotation wins for that job. Nothing said verbally is binding on either of us unless it is confirmed in writing (a WhatsApp message or email counts).

1.3 Changes to these terms

We may update these terms from time to time. The version on this website at the time you book is the one that applies to that booking.

2. Our services and standards

2.1 What we do

  • Boiler installation (combi, system and regular boilers)
  • Boiler repairs and fault finding
  • Annual boiler servicing
  • Landlord gas safety certificates (CP12)
  • Emergency plumbing and heating repairs
  • Central heating, radiators, underfloor heating and powerflushing
  • General plumbing

2.2 Gas Safe

All gas work is carried out by Gas Safe registered engineers in line with the Gas Safety (Installation and Use) Regulations 1998, current Building Regulations and the manufacturer's instructions. Every engineer carries a Gas Safe ID card, and you can check our registration number on the Gas Safe Register before we arrive. Where the work requires it, we notify Building Control and provide the relevant certificate.

2.3 Workmanship

We carry out all work with reasonable skill and care, to industry good practice and the manufacturer's guidelines. We keep the working area tidy and leave it as we found it, allowing for the work done.

2.4 Safety first

If we find an appliance or installation that is unsafe, we are required to make it safe. That may mean disconnecting an appliance or turning off a supply and labelling it. We will explain why, tell you what is needed to put it right, and will not leave an unsafe situation because it is inconvenient.

3. Quotations and pricing

3.1 Free quotations

Quotations for installations and planned work are free and without obligation. A quotation is valid for 30 days from the date we issue it. Some jobs need a survey before we can give a firm price.

3.2 Fixed prices

Where we give you a fixed price in writing, that is the price you pay for the work described, including labour, materials and VAT unless the quotation says otherwise. It only changes if the scope changes (see 3.4).

3.3 Repairs, call-outs and hourly work

For repairs, fault finding and emergency call-outs we tell you the call-out or first-hour charge before we attend. Once the engineer has diagnosed the fault we tell you the cost of the repair before doing it, so you can decide whether to go ahead. Parts are charged at the price stated on your invoice.

3.4 Extra work

Sometimes a job uncovers something the quotation could not have allowed for: a hidden defect, pipework that does not meet current regulations, or something you ask us to add on the day. We will explain what we have found and agree the extra cost with you before doing it. We do not carry out chargeable extra work without your say-so.

3.5 Materials

Materials we supply remain our property until they are paid for. Where you supply your own materials or appliances, we fit them in good faith but cannot guarantee them, and any fault in them is between you and the supplier.

4. Payment

4.1 No deposits

We do not take deposits or payment in advance. You pay for the work once it is done.

4.2 When payment is due

We invoice on completion of the work. Payment is due on receipt of the invoice, and in any case within 7 days, unless we have agreed something different in writing. For longer installations we may agree staged invoices with you in advance, each for work already completed.

4.3 How to pay

  • Bank transfer (our details are on the invoice)
  • Debit or credit card
  • Cash

4.4 Late payment

If an invoice is not paid on time we will remind you first. If it remains unpaid we may charge interest at 8% above the Bank of England base rate from the due date, and recover reasonable costs of collecting the debt. We may also pause any guarantee work until the account is settled.

5. Guarantees and warranties

5.1 Workmanship guarantee

Our workmanship is guaranteed for 12 months from the date of completion. If something we installed or repaired fails because of the way we did the work, we come back and put it right at no charge. The guarantee is for the work itself; it does not cover wear and tear, misuse, damage caused by others, or faults in parts of the system we did not work on.

5.2 Parts

Parts we supply carry the manufacturer's warranty. If a part fails within its warranty we will help you claim under it, and where the failure is covered we replace the part without charging for the part.

5.3 New boilers

New boilers come with the manufacturer's warranty, which for the brands we install can be up to 12 years depending on the model. We register the warranty for you. Manufacturers require the boiler to be serviced every year by a Gas Safe registered engineer to keep the warranty valid; that can be us or another registered engineer, but it does have to happen.

5.4 What guarantees do not cover

  • Misuse, neglect or modifications by anyone other than us
  • Damage from outside causes such as freezing, flooding, power surges or building works
  • Normal wear and tear, and consumables
  • Systems that have not been maintained as recommended (for example, low inhibitor levels or missed annual services)
  • Pre-existing faults in parts of the system we were not asked to work on
  • Work done on the system by someone else after we finished

6. Appointments, cancelling and rearranging

6.1 Booking

Appointments are booked subject to availability and confirmed by phone, WhatsApp or email with a date and an arrival window. Someone aged 18 or over needs to be at the property while we are there.

6.2 If you need to cancel or move an appointment

Just let us know as early as you can, by phone or WhatsApp, and we will rearrange. There is no cancellation fee. As there is no deposit, there is nothing to refund. If we have already ordered materials specifically for your job, such as a boiler or a made-to-order part, we will ask you to cover the cost of anything that cannot be returned, and we will tell you before we order.

6.3 If we need to cancel

Occasionally an emergency, illness or the weather means we cannot make an appointment. We will tell you as soon as we know and offer the earliest alternative.

6.4 Access

Please make sure we can get to the boiler, cylinder, pipework or appliance we are there to work on, and that pets are kept out of the way. If our engineer arrives and cannot get in or cannot reach the work, we will try to contact you and rearrange; for repeated wasted visits we may ask for the call-out charge before rebooking.

7. Liability and insurance

7.1 Insurance

We hold public liability insurance covering damage to property and injury to people arising from our work. A copy of the certificate is available on request.

7.2 Our responsibility to you

We are responsible for loss or damage you suffer that is a foreseeable result of our breaking this contract or failing to use reasonable care and skill. We are not responsible for losses that are not foreseeable, for business losses, or for loss or damage caused by something outside our control. Nothing in these terms limits our liability for death or personal injury caused by our negligence, for fraud, or for anything else the law does not allow us to limit.

7.3 Existing systems

Working on an older heating or plumbing system can occasionally disturb a weakness that was already there, such as a corroded pipe, a seized valve or a radiator that will not hold pressure once the system is cleaned. We take care to avoid this, and we tell you about anything we are concerned about, but we are not responsible for pre-existing faults or hidden defects in parts of the system we were not asked to work on.

7.4 Making good

Where the job involves lifting floorboards, cutting into walls or running pipework through the building, we make good to a sound, tidy finish. Decoration, tiling, flooring and carpentry are not included unless your quotation says so.

8. What we ask of you

  • Tell us what you know about the property and the existing system, including any previous problems
  • Give us safe, clear access to the working area and move anything fragile or valuable out of the way
  • Keep pets away from the working area
  • Make sure gas, electricity and water are available for the work
  • Tell us about any known asbestos or other hazardous materials
  • Get the permissions you need before we start (for example, your landlord's consent if you rent)
  • Have the boiler serviced every year to keep the manufacturer's warranty valid
  • Tell us promptly if you have a problem with our work so we can put it right

9. If something goes wrong

9.1 Tell us first

If you are not happy with anything, call or message us and we will sort it out. Most problems are fixed with a return visit. If you would rather put it in writing, email enquiries@plumblinemk.co.uk; we acknowledge within 2 working days and give you a full response within 14 days.

9.2 Your right to a repair

Under the Consumer Rights Act 2015 you are entitled to have work that was not done with reasonable care and skill put right at no cost to you, within a reasonable time. That is what our workmanship guarantee is for.

9.3 If we cannot agree

If we cannot resolve a complaint between us, you can contact the Gas Safe Register (for gas safety concerns), your local Trading Standards office, or the Citizens Advice consumer service for independent help.

10. Your consumer rights

10.1 Statutory rights

Nothing in these terms affects your statutory rights as a consumer, including your rights under the Consumer Rights Act 2015 that services are carried out with reasonable care and skill and that goods are of satisfactory quality.

10.2 Cooling-off period

If you agree to work with us by phone, message or email rather than in person, the Consumer Contracts Regulations 2013 give you 14 days from that agreement to change your mind. If you ask us to start within those 14 days and then cancel, you pay for the work done up to that point; once the work is complete the right to cancel ends. Urgent repairs you ask us to carry out straight away are not covered by the cooling-off period.

11. Your data

We handle your personal information in line with UK GDPR and the Data Protection Act 2018. Our Privacy Policy explains what we collect, why, and how long we keep it.

12. Governing law

These terms are governed by the law of England and Wales, and any dispute will be dealt with by the courts of England and Wales. If any part of these terms is found to be unenforceable, the rest still applies.
