Software for Energy Assessors: What to Look For
If you've typed "software for energy assessors" into Google, you've probably found two kinds of results: the accredited lodgement tools you already use to produce a certificate, and a pile of generic CRMs that have never heard of an EPC. Neither quite fits.
I'm a working domestic energy assessor. I ran my round on WhatsApp, a spreadsheet and a paper diary for years before I built something better. Here's what I learned about what this software should actually do — and what's just noise.
Lodgement software is not business software
First, a distinction that trips a lot of people up. Your lodgement software (Elmhurst, Stroma, Quidos and the rest) exists to produce and lodge the certificate to the correct standard. That's essential, and you shouldn't replace it.
But it was never designed to run your business — the bookings, the invoices, the estate-agent relationships, the chasing, the compliance paperwork. That's a separate job, and it's where most of your unpaid admin hours disappear. Good software for energy assessors fills that gap and works alongside your lodgement tool, not against it.
The features that actually save hours
When you strip away the marketing, only a handful of things move the needle for a sole trader or small firm.
A booking page that does the typing for you
If customers and estate agents can book you directly from a branded page, you stop playing phone tag and stop re-typing addresses off text messages. Every booking should land in one place with the details already filled in.
Invoices that chase themselves
The single biggest cash-flow leak for assessors is forgotten invoices. Look for one-click branded invoices with a payment link, and an outstanding-payments view that shows you who's overdue without you having to remember. If you do estate-agent work, batch invoicing — one monthly invoice per agent instead of certificate-by-certificate — is worth the subscription on its own.
Estate-agent management
Agents are most assessors' biggest source of work, and also the fiddliest to bill. Agreed pricing per agent, a record of every job, and clean monthly billing keep that relationship smooth — which keeps the work coming.
Compliance you don't have to think about
Insurance, DBS, accreditation, CPD and your survey evidence should live in one place, so a QA audit is a non-event rather than a weekend of scrambling. An evidence vault tied to each job is the quiet feature you'll be grateful for later.
The features that sound good but rarely matter
- Endless integrations you'll never connect.
- Dashboards with 40 charts when you needed three numbers: jobs this month, money owed, jobs booked.
- Anything that duplicates your lodgement software. If a tool is racing to also be your RdSAP engine, you're paying twice and learning two systems.
Buy for the work you actually do, not the demo.
Don't forget where the market's going
EPCs aren't going anywhere — they're a legal requirement to sell or let. But the bigger story for the next five years is retrofit. The Warm Homes Plan is putting billions into home upgrades, and PAS 2035 retrofit assessment is becoming a real income stream for assessors who are ready.
When you choose software for energy assessors, think one step ahead: can it grow with you from EPC work into retrofit, so you're not switching tools again in eighteen months?
A quick buyer's checklist
- Works alongside your accredited lodgement software
- Branded booking page customers can self-serve
- One-click invoices + an overdue-payments view
- Estate-agent batch invoicing
- Evidence vault, CPD and compliance in one place
- A genuine free plan so you can try it on a real job
- Built by someone who understands EPCs — not a generic CRM
The honest test
The best way to judge any tool is to run one real job through it, end to end: take the booking, do the assessment, send the invoice, get paid. If that whole loop is faster and calmer than your current setup, it's earning its keep.
That's exactly why I built Domestic Energy Assessors — to run my own round, then opened it up to other assessors. It's free to start, no card needed, and it sits alongside the lodgement software you already trust.
