Electrical Estimating Programs: How to Quote Jobs Faster Without Underpricing
A 25% markup is only a 20% margin — is your estimating software doing that maths for you? Here's how UK electricians pick quoting tools without quietly underpricing every job.
The maths problem hiding in your quoting spreadsheet
Here’s an uncomfortable one for you: if you mark up a job by 25%, your margin isn’t 25%. It’s 20%.
Say the job costs you £1,000 in materials and labour. Add a 25% markup and you’re quoting £1,250. Profit is £250 on a £1,250 job — that’s a 20% margin, not 25%. Do that maths on every quote for three years and you’ve quietly underfunded your own profit by 5 points on every single job you’ve ever won. Nobody stole from you. You just did the markup vs. margin sum wrong, and so did the sparky who trained you.
That’s the real reason so many electrical firms are hunting for electrical estimating programs right now — not because spreadsheets are slow (they are), but because a decent chunk of quotes built on gut-feel markup are quietly bleeding margin before the van’s even loaded. UK electrical contractors are supposed to be running 65-67% gross margin on residential service work, and 30-50% on commercial project work, according to Simpro’s benchmarking data. A lot of shops are nowhere near that. Not because the work’s priced too cheap for the market — because the estimating math never separated markup from margin in the first place.
We’ll get to the tools. But the tool is only as good as the numbers you feed it.
What quoting software for electricians actually needs to get right
Every vendor page you’ll find searching “electrical estimating programs” talks about takeoff speed, item counts, and templates. Fine. But speed on a wrong number just means you lose faster.
Three things matter more than how quickly the software draws a takeoff:
Different markup by material category. Wire and conduit — the bulk commodity stuff — typically carries a 1.25x (25%) markup. Small parts, connectors, glands? Contractors routinely mark those up as high as 6x, blending across a job to something like 1.3x-1.5x overall, per Buildforce’s pricing data. A single blanket markup rate across every line item either prices your wire out of the market or gives away margin on hundreds of small connectors per job. If your quoting software for electricians can’t set that at a category level, it’s costing you money on every quote it produces.
Labour burden baked in, not bolted on. Labour markup typically runs 25-50% above the bare hourly wage to cover burden — insurance, holiday pay, van costs, tools. In union-heavy markets that burden alone can add 35-40% before profit is even applied, according to Cyanbuild’s construction markup research. If your estimating tool has your labour rate as a flat hourly figure with no burden layered in, you’re quoting your wage bill, not your business’s actual cost of putting an electrician on site.
Material prices that move with the market, not with your last price book update. Copper wire jumped 5.3% in a single quarter and is up 18.4% year-over-year as of Q2 2026, according to Gordian’s cost index. A quote built on 90-day-old copper pricing can be underwater before you’ve even ordered the drum. Static price books were fine when copper moved slowly. It doesn’t any more.
None of this is exotic. It’s the difference between software that helps you win the right jobs and software that just helps you lose money quicker.
The gap generic templates leave
The reason electrical-specific estimating tools exist at all — rather than everyone just using a generic construction template — comes down to reference data. PermitFlow’s analysis points out that generic platforms lack the built-in electrical databases, labour unit libraries and code references that trade-specific tools bake in from day one.
The gold standard for labour units in the industry is NECA’s Manual of Labor Units — the reference vendors like McCormick Systems build their labour databases around (NECA, McCormick Systems). If your software’s labour hours per point are pulled from a proper standard, you can defend your labour line item to a price-sensitive customer instead of shrugging and saying “that’s just what it takes.” In a market where electricians are the scarcest input you’ve got — the trade’s short-handed enough that job openings are projected to run around 81,000 a year through 2034 — that labour hour is the thing you can least afford to underbid.
If you’re doing commercial or industrial work, there’s one more line item most estimates simply skip: project management time. Treating PM hours as overhead instead of billing for them is documented to cause a 10-20% margin loss per project. That’s not a rounding error — that’s the difference between a 30% margin job and a 12% one. Any estimate on a job with a site manager, RAMS, or multiple trades on-site needs a PM line, even if it feels awkward to put a number against “sorting stuff out.”
What to actually budget for the software
By shop size, entry-level electrical estimating software runs roughly £25-£250 a month for a 1-5 person operation, climbing well into four figures a month once you’re a 5-20 person mid-size contractor bidding volume commercial work, based on Software Advice’s cost breakdown. The bigger the shop, the more the tool costs — but the ROI only stacks up once you’ve got enough estimators and enough bids in flight to need multi-user takeoff and change-order tracking.
In the UK, the tools that show published pricing publicly are worth naming. Tradify runs £34-£44 per user per month across its Lite, Pro and Plus tiers — job management with quoting built in, rather than pure estimating. Clik Compliance — built more for certification than estimating, but often mentioned in the same breath — runs £20-£25 per user per month depending on tier. Others like Commusoft, ServiceM8, Joblogic, Simpro and Payaca are quote-only, so you’ll need a call before you know what you’re signing up for. EasyCert, by contrast, sells a one-off perpetual licence rather than a subscription — worth knowing if monthly software costs are what’s putting you off in the first place.
Don’t let a mid-market tool built for 5-20 user teams talk you into a four-figure monthly plan when you’re a 3-person shop bidding a handful of domestic rewires a month. If you’re still hand-quoting from a spreadsheet with sensible markup categories built in, that’s a legitimate stage to be at — just make sure the maths inside the spreadsheet is right.
Track your hit rate, not just your quote speed
Here’s a diagnostic most electricians never run: your bid-hit ratio. Typical competitive private work runs a 15-25% win rate — roughly one win in four bids, per ConstructConnect’s and iBEAM’s benchmarking. If you’re winning nearly everything you quote, you’re underpriced — full stop. If your ratio drops below 10% (worse than 10-to-1), Sunflower Bank’s guidance flags that as a sign your estimating costs — the hours you’re spending building quotes — outweigh what you’re winning from them.
Run that number for your last twenty quotes. It’ll tell you more about whether your estimating process is working than any software feature list will.
Where Hero AI fits — after the quote’s built
Estimating software gets the number right. What happens after you send it is a separate problem, and it’s the one that actually costs contractors the most sleep. A Good/Better/Best quote sitting in someone’s inbox for four days is a quote a competitor’s about to win instead. Hero AI drafts that Good/Better/Best breakdown straight from a voice note in under a minute, so the estimate lands while the customer’s still standing in their kitchen thinking about it — not three jobs later when you finally get round to typing it up.
And once the quote’s accepted, Hero AI answers the calls that come in while you’re up a ladder, chases the deposit and the final invoice without you having to ring round, and keeps your day routed so the estimating time you did put in doesn’t get eaten by drive time and double-booking. We wrote about the certification side of this — CP12s, EICRs, minor works — in our guide to EICR software and auto-generating certificates, and if you want the full run-down on where Clik, Megger CertSuite and EasyCert sit against an AI-run back office, that’s in our NICEIC cert software comparison.
None of that replaces getting your markup categories, labour burden and PM time right in the estimate itself — that’s on you and whichever estimating program you pick. But once the number’s right, everything downstream of “quote sent” is where a lot of small electrical firms lose the job anyway. That part, Hero AI can run for £19.99 a month.
