The problem

What wastes time for plumbers

Three situations you will recognise if you price plumbing jobs yourself.

  • The quote happens at night, not on site

    You jot three words in a notebook between jobs, then reconstruct everything at 9 pm. By then the fitting detail or the length of multilayer pipe is gone - and the client has already called someone else.

  • Call-outs go out without a written quote

    A call-out priced only verbally is a disputed invoice. A written quote is the proof of the price you announced - and the document you send before you start.

  • The same services, retyped every time

    Mixer tap replacement, leak detection, wall-hung WC: always the same lines. Rewriting them by hand in a spreadsheet is billable time lost every week.

The method

A plumbing quote in three steps, without going back to the office

The quote happens when every detail is still fresh: on site, not at night.

  1. Step 1

    You dictate on site

    From your phone, describe the job like you would to the client. No form, no dropdown.

  2. Step 2

    Devia structures and prices

    Each service becomes a line with quantity, unit and the price from your catalogue. Nothing invented: your rates.

  3. Step 3

    You review and send

    Adjust if needed; the PDF is generated in your brand colours and sent to the client. The invoice follows without retyping.

VAT

Which VAT rate on plumbing work?

The rate is chosen line by line in Devia - essential when a job mixes several types of work.

  • 20 %

    Most plumbing repair, maintenance and installation work.

  • 5 %

    Qualifying energy-saving materials and some residential energy work.

  • 0 %

    Certain new-build and zero-rated supplies, when they apply.

VAT depends on the nature of the work and your VAT registration. If in doubt, check with your accountant: Devia applies the rate you choose, line by line.

Compliance

Required mentions on a plumbing quote

A plumbing quote should identify your business (including Companies House and VAT numbers where relevant), the client, the job address, each line with quantities, VAT and totals. Devia fills this from your company profile.

  • Date and validity period

    Issue date and the period during which the price remains guaranteed.

  • Company identity

    Legal name, address, Companies House number, legal form and VAT number if registered.

  • Client identity and job address

    Client name and address, and the works address if it differs.

  • Itemised breakdown

    Each service and material with quantity, unit and unit price excl. VAT.

  • Labour and call-out

    Hourly rate or labour lump sum, and call-out fees where applicable.

  • Totals and VAT

    Overall total excl. VAT, VAT rate and amount per line, total incl. VAT due.

  • Professional insurance

    Insurer details, policy reference and geographic cover.

  • Client signature

    The wording “quote received before work starts”, date and signature.

A written quote is not always a legal requirement in the UK, but it is the document that protects you if the client disputes the price. Devia produces it before you start.

FAQ

Frequent questions from plumbers

Answers to the questions that come up most often before getting started.

How do I produce a plumbing quote quickly?

From your phone, on site, you describe the job out loud as you would to the client. Devia transcribes, splits it into service lines, applies your catalogue prices and generates the PDF. You review, adjust if needed, and send - usually in under two minutes.

Is a quote mandatory for a plumbing call-out?

A written quote is not always a legal requirement in the UK, but it is the document that protects you if the client disputes the price. Devia produces it before you start, from the job you just dictated.

What must a plumbing quote contain?

Your company identity (legal name, address, Companies House number, VAT number if registered), the client, the job address, each service and material with quantity and unit price, labour or call-out, totals excl. and incl. VAT, validity period, and insurance details where they apply.

Which VAT rate applies to plumbing work?

Most plumbing work is standard-rated at 20 %. A reduced 5 % rate can apply to qualifying energy-saving materials, and 0 % to certain new-build supplies. In Devia the rate is set per line so mixed jobs stay on a single quote.

Does Devia understand plumbing vocabulary?

Yes. Multilayer, PEX, copper, fitting, trap, mixer tap, cistern, waste: site language is recognised on dictation, without you having to speak like software. You say “I'm changing the thermostatic mixer”, and the line comes out with the right label.

Can I turn the quote into an invoice and track deposits?

Yes. Once the quote is accepted, the invoice is created from the same document, without retyping. You manage deposits, progress invoices and reminders, and you export turnover reports for your filings.
