The difference between a business that looks professional and one that does not is rarely talent. It is whether the paperwork is built once and reused, or rewritten from scratch at nine at night after a twelve-hour day.
A template is not a document. It is a decision you make once so you never have to make it again while tired.
The rule: business things are constant, job things are variable
Sort every element of an estimate into one of two buckets. If it is about your business, it belongs in the template and never changes. If it is about this job, it is a blank you fill in.
| Constant (build once) | Variable (per job) |
|---|---|
| Logo, colours, typeface | Customer name and site address |
| Legal and company details | Job reference and date |
| Registrations and accreditations | Scope of works |
| Terms and conditions | Line items and prices |
| Payment terms and deposit policy | Job-specific assumptions |
| Late payment clause | Job-specific exclusions |
| Validity period | Provisional sums |
| Variation process | Programme and start date |
| Standard exclusions | Totals and VAT |
| Guarantee and insurance statement | |
| VAT position |
Most people have this backwards. They rewrite the terms every time, badly and differently, and copy the previous customer’s address by accident.
The masthead
Your name, big and clear. A logo if you have one, plain text if you do not: a clean typographic name beats a bad logo every time, and a bad logo actively costs you credibility.
Then the details you are obliged to give. A limited company must show its registered name, company number, place of registration and registered office address on its business documents under the Companies Act 2006. A sole trader using a trading name must give their own name and an address where documents can be served.
Then the signals that reassure a stranger: Gas Safe, NICEIC, NAPIT, TrustMark, your trade body, your public liability cover. These are the reason a customer picks you over the man with the Hotmail address and no letterhead.
The static blocks
Write these once, properly, and never touch them again except at an annual review.
Payment terms
Be specific and put a number of days on it. “On completion” is not a payment term, it is an aspiration.
Payment is due within 14 days of the invoice date. A deposit of 30% is payable on acceptance and is applied to materials. On jobs exceeding £5,000 an interim payment will be invoiced at the midpoint stage.
Deposits and staged payments are worth their own thought, and there is more on structuring them in getting paid on time.
The late payment clause
This one is worth understanding properly, because the right is different depending on who owes you money.
For business customers, the Late Payment of Commercial Debts (Interest) Act 1998 gives you a statutory right to charge interest on a commercial debt at 8 per cent above the Bank of England base rate, plus a fixed compensation sum that steps up with the size of the debt. That right exists whether or not it is written in your contract. The base rate used is the one in force at a fixed reference date each half year rather than the rate on the day, so check the current mechanism and the compensation bands on GOV.UK before you invoice interest.
For domestic customers that Act does not apply. To charge a consumer interest you need a term in your contract saying so, agreed before the work starts, and it has to be fair and transparent under Part 2 of the Consumer Rights Act 2015. A modest, clearly worded rate is defensible. A punitive one may be unenforceable, and trying it on can cost you more than the debt.
So the template needs the right sentence for the right customer:
Commercial: We reserve the right to claim statutory interest and compensation under the Late Payment of Commercial Debts (Interest) Act 1998 on invoices paid late.
Domestic: Invoices unpaid after 14 days may attract interest at 4% per annum above the Bank of England base rate, calculated daily from the due date.
If the amounts are significant, have your wording checked by a solicitor or your trade body rather than copying it from a forum.
Validity period
This estimate is valid for 30 days from the date shown.
One line, and it closes off the argument about the customer accepting a price you gave last spring.
The variation clause
The most valuable sentence in the whole template:
Any work outside the scope described above will be agreed with you in writing, with a price, before it is carried out.
It protects you, it reassures them, and it commits you to a habit that prevents most disputes. Why that matters legally is covered in how binding is an estimate.
Guarantee and insurance
State your workmanship guarantee and its length, and say that manufacturer warranties on materials are passed to the customer. State your public liability cover and the insurer if you like. This is a selling point sitting in the small print, so do not bury it.
Standard exclusions
The ones that apply to almost every job in your trade. Asbestos, structural work, building control fees, decoration, works to anything found defective once opened up. Job-specific exclusions get added on top.
The consumer cancellation notice
If you agree contracts in customers’ homes, the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 require you to give the consumer specific information including their right to cancel within 14 days, in a durable form, before the contract is made. Build the notice and the cancellation form into the template as an appendix and it is handled forever. Leave it out and you are exposed on every job.
The per-job blanks
Keep this list short, because every blank is something you can get wrong at the end of a long day:
- Customer name, site address, billing address if different
- Reference and date
- Scope paragraph
- Line items
- Job-specific assumptions
- Job-specific exclusions
- Provisional sums
- Totals and VAT
- Start date and duration
Numbering and version control
Give every estimate a unique reference. A simple scheme is fine: 2026-0147, or initials plus a sequence. What matters is that it is unique and it never gets reused.
When you revise a price, do not overwrite. Issue 2026-0147 Rev B and keep Rev A. When a customer says “you told me £3,200”, you want to be able to say which document, which revision, which date. Overwriting is how you lose an argument you would otherwise win.
Format
Work in something editable, send a PDF. A Word or equivalent master lets you revise fast; a PDF is what should reach the customer, because it renders identically everywhere, prints properly and cannot be casually altered.
Name the file so it means something on the customer’s desktop three weeks later: Estimate 2026-0147 - 14 Elm Road - Bathroom.pdf, not estimate final v2 (1).pdf.
Testing it
Before you use a new template in anger, send one to yourself and open it on a phone. Most customers will read it on a phone first. Check that:
- the total is visible without pinching
- the scope reads clearly in a small font
- your phone number is tappable
- the terms are legible rather than 6pt grey
- nothing from the previous job survives in it
That last one is the classic template failure. One customer’s name left in the header of another customer’s estimate undoes every bit of credibility the template was built to create.
Review it once a year
Rates change, insurance changes, registrations renew, and legislation moves. Put an annual reminder in your phone to reread the static blocks with fresh eyes. Ten minutes, once a year.
The honest limitation of a template is that it only handles the constant half. The scope paragraph, the line items and the job-specific assumptions still have to be written, and that is the part that actually takes the evening. TradeScribe fills that half from your rough notes and drops it into your own template, so the document that comes out is yours rather than someone else’s house style.
