The problem
What wastes time for heating engineers
Three situations you will recognise if you price heating jobs yourself.
The method
A heating quote in three steps, without going back to the office
The quote happens when every detail is still fresh: on site, not at night.
- Step 1
You dictate on site
From your phone, describe the job like you would to the client. No form, no dropdown.
- Step 2
Devia structures and prices
Each service becomes a line with quantity, unit and the price from your catalogue. Nothing invented: your rates.
- 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.
Concrete example
What a heating quote looks like with Devia

Your trade
Devia knows heating vocabulary
You speak like on site, not like to software. Labels come out correctly on the document the client reads.
VAT
Which VAT rate on heating work?
The rate is chosen line by line in Devia - essential when a job mixes several types of work.
20 %
Most heating 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 heating quote
A heating 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.
« In peak season I do eight services a day. Catalogue packages drop into the quote on their own - I no longer retype anything. »
FAQ
Frequent questions from heating engineers
Answers to the questions that come up most often before getting started.
How do I produce a heating quote between jobs?
You dictate what you found and what you propose, from the van. Devia structures the quote, pulls your service packages and parts prices, and produces the PDF. The client receives it before your next visit.
How do I price a heat-pump installation?
Split supply of the equipment, removal of the old system, hydraulic and electrical connection, commissioning and any power flush. That breakdown is what the client - and the body paying the grant - expects to see on the quote.
Can I manage recurring service contracts?
Yes. Your service packages live in your catalogue: you recall them with a word on dictation, and both quote and invoice generate the same way from one client to the next, with no risk of dropping a line or using the wrong price.
Is a quote mandatory for a heating 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.
Which VAT rate on a heat pump?
Most heating 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.
Is heating vocabulary recognised?
Yes: boiler, heat pump, radiator, underfloor heating, power flush, expansion vessel, thermostat. You describe the system in your own words and the labels come out correctly on the document the client reads.
