Bathroom Installation Service Agreement Contract Template

Get Paid On Time. Avoid Disputes. Look Professional.

Built by bathroom installers. Adjusted by solicitors.

At Construction Companion, we know from real on-site experience how to put domestic clients at ease. Clear wording, practical detail to show your expertise, and firm payment terms that don’t come across as intimidating. Everything’s written to hold up under UK law.

Most small business owners in the trade don’t realise how much legal protection they’re missing out on — solid Terms & Conditions can protect your business in ways you’ve probably never even considered.

If you're installing a new bathroom and want to look professional, our Terms & Conditions have you covered. Use the full contract, or simply attach the pre-made quote Terms & Conditions to your proposal when pricing a job.

Our document templates don’t just gather dust in the van. It’s a one-off purchase you’ll use again and again — on every job.

Think of our documents as your business partner. They protect your business behind the scenes while you work — preventing disputes, backing you up legally, and helping you get paid on time without the back-and-forth.

It’s trade knowledge and legal expertise, combined. Whether it’s friendly, polite wording about what to expect during the bathroom installation, or serious legal terms around late payment penalties — it’s all there to protect you and your business.

“From explaining the impact of late payments on scheduling, to setting out over-ordering allowances and confirming how bathroom use will be managed during the project, it’s all clearly set out in our terms — saving you from awkward conversations later.”

Let your Terms & Conditions do the talking. Customers know what to expect, and you come across as professional and organised from the start.

If something goes sideways — a dispute, late payment, or a customer complaint — this gives you the confidence of knowing you’ve handed over professional, legally backed terms from day one.

Our documents are updated regularly to reflect changes in UK law and the common disputes installers face on the job. If you’ve done the work properly and sent over our quote terms, the contract, or both — you’ll be in a strong position.

Feel secure knowing you’ve clearly set expectations in writing, and you’re protected if things ever need to be escalated.

The Terms & Conditions work for you before you even arrive on site. Your client knows what to expect ahead of time — from limited bathroom use during works and utility interruptions to room clearance and delivery storage — all worded in a polite, professional manner.

• ✔ Keeps payments on track – Clearly sets out payment schedules, due dates, deposit terms, and consequences for non-payment.

• ✔ Protects against liability – Covers trade-specific risks like hidden damp, rot, asbestos, faulty plumbing or electrics.

Trade Experience

We’re the only online document store built by tradespeople and a legal team working together. The trades bring the on-site experience; the legal team makes it professional.

Legal Knowledge

Our installers know the problems — the solicitors know how to protect against them. Every document is reviewed and refined to stay legally compliant, reduce your liability, and protect your income.

“Most tradespeople don’t realise how much protection they’re missing out on — and honestly, neither did our own installers until the legal team walked them through it.”

This contract is designed for jobs where your quote terms alone aren’t enough — when you need broader protection and more legal weight behind your terms.

It still includes key clauses from the quote Terms & Conditions, but goes further. It’s the result of real collaboration between our installers and legal team until every scenario is covered.

“Use the contract when there’s more risk, more money, or more uncertainty involved — covering every angle and leaving nothing to chance.”

Polite but firm terms for quoting — widely used across the industry. These are the terms you send alongside your quote.

They state when payment is due and let you set your own timeframe — on completion, within 7 days, or 30 days. Fully editable to suit your business.

Late payment fees are included too — based on what you’re legally allowed to charge. (Most trades get this part wrong and break consumer law.)

The Quote Terms also include clear clauses from the full contract — liability, site access, and more — with friendly, informative wording for day-one expectations.

Attach this professional template to your invoice to reinforce the payment terms agreed before the job started.

Invoice Terms act as a reminder — restating the rules your client accepted and the consequences if those terms are broken.

This simple step — when used alongside our contract or Quote Terms — leads to invoices being paid on time, every time.

• Accepted Payment Methods – Deposit schedules, methods & timing.
• Firm Payment Terms – Late fees & non-payment actions.
• Polite, Informative Terms – Temporary bathroom use, safety guidance, over-ordering allowances.

• Additional Work – Client-requested extras & unforeseen conditions.

You’re covered for working during the 14-day cooling-off period under the Consumer Rights Act 2015. Even if a customer cancels, you’re still entitled to payment for work already done — as long as the paperwork’s in place.

Clear terms around cancellations and disputes give you something to fall back on if things go off track mid-job. All documents meet legal standards for domestic work across the UK.
