What heating engineers need from a CRM

How Unavoidable CRM helps heating engineers

What it costs

Every plan has every feature. You choose by people and contacts: Solo £29 a month (1 user, 1,000 contacts), Team £149 (5 users, 10,000 contacts) and Agency £399 (unlimited users and contacts, plus white-label). Paying yearly saves 20%. Email sending is included. Texts, calls and AI receptionist minutes go on your own Twilio and Retell accounts at the provider’s price, with no markup.

For a one-person business the Solo plan at £29 a month is usually enough. As a rough guide, 150 minutes of AI receptionist time a month is £15 to £22.50 at provider prices, and a UK number is about £2.65 a month.

How to try it properly

Use the 14-day trial on a real week. Point your missed calls at the AI receptionist, send your next few quotes through the CRM and let the follow-ups run. Then count how many enquiries you would otherwise have lost. If you want a hand setting it up, every plan includes a free 15-minute call with Andrew, the founder.
