Built for the whole job, not just the design
A heat loss report doesn't quote the job, book it in, issue the Benchmark certificate or chase the invoice. TradePlanr handles everything after the design — for every trade you work in.
Heat loss designs are one job — TradePlanr runs the rest of your week
Heat Engineer is a specialist heat loss and system design tool. TradePlanr is the business side: quotes, job diary, certificates, digital sign-offs, invoices and card payments — a flat £9.99/month with a genuine free plan.

Switching FAQs
Is TradePlanr an alternative to Heat Engineer?
They solve different problems. Heat Engineer is a specialist heat loss and system design tool — and a good one. TradePlanr runs the business side of a heating firm: quotes, job diary, certificates, digital sign-offs, invoices and payments. If you searched for heating engineer software to run your day-to-day work, TradePlanr is the tool for that; many installers use a design tool alongside it.
Does TradePlanr do heat loss calculations?
TradePlanr includes free trade calculators (gas rate, system volume, expansion vessel sizing and more), but it doesn't produce room-by-room MCS heat loss reports — that's Heat Engineer's specialism. TradePlanr focuses on running the jobs, paperwork and payments around the install.
How much does each cost?
TradePlanr is a flat £9.99/month (or £99.99/year) with a genuine free plan. Heat Engineer's published pricing starts at around £10+VAT a month for sole traders for its design tools, with one-off survey pricing also available — check their site for current plans. The point isn't which is cheaper; it's that TradePlanr covers the business side a design tool doesn't.
Can I issue Benchmark and gas certificates with TradePlanr?
Yes. TradePlanr issues Benchmark commissioning certificates, landlord gas safety records (CP12), service records and dozens of other certificates from your phone, with digital customer signatures.
Is there really a free plan?
Yes — a genuine free plan, not a trial that expires. Start creating jobs, quotes and invoices for free with no card. Pro (online payments and more) is £9.99/month or £99.99/year with a 7-day free trial when you're ready.
