You are nine hours into ripping out an old bathroom. Back is shot, knuckles grazed from an obstinate brass compression fitting, dust in your hair. Crawling home down the bypass, engine idling, grease on your hands. Phone pings on the mount: three WhatsApps. Homeowner in Guildford wants to know what knocking a dining room wall through will run to. Landlord in Bristol needs a consumer unit change-out before new tenants move in. Someone in St Albans is panicking over a roof leak after the wind yesterday.
You mutter the usual excuse: Sunday night. I will get the laptop out with a cup of tea, price the gear at the merchant, and bash out the numbers.
Sunday night comes. You are shattered. You stare at a battered Excel grid from 2021 with dead macros, flicking through blurry phone photos, guessing what copper fittings cost this week. By Tuesday morning when your PDF finally lands in their inbox, the client texts back: 'Sorry mate, had another bloke around Friday who sent a price that evening. He is on site already.' That is thirty-five grand a year walking out the door for the sake of slow paperwork.
⚡ Key Takeaways
- Nearly four out of five trade jobs (78%) go to whoever gets an itemized price into the client hands first. Delaying quotes to the weekend costs a busy sole trader thirty-five thousand pounds a year in silent losses. An estimate is an educated ballpark (+/- 15% to 20%) that protects you when walls hide rotten lintels; a quote is a locked legal contract where price hikes come straight out of your pocket. Winning paperwork separates labour, materials, plant, and waste clearly, locking in a 20% to 50% deposit before tools leave the van. And modern outfits do not spend Sundays typing in Word: they run WhatsApp intake that turns photos and 30-second voice notes into professional, itemized PDFs while they are still on the job.
This guide gives you the exact tools to fix your quoting speed today: the real legal differences between estimates and quotes, the core elements of an airtight price, seven trade-specific copy-paste templates, and the mobile workflow that gets quotes out in under ten minutes.
Call a fixed quote an estimate and you invite arguments. Call an open-ended estimate a quote and you end up footing the bill for four days of rotten floor joists. Under English law, these words are not loose trade slang — they dictate who bleeds cash when a job goes sideways.
An Estimate is what you say before the crowbar goes in, when plasterboard hides the joists and turf hides the drainage. Educated ballpark, fifteen to twenty percent either way, with the caveat said out loud: 'surface looks like this — damp joists or 1974 wiring get priced if we find them.' Write the visible-conditions clause on the paper itself. Otherwise you're gambling your margin on somebody else's hidden brickwork.
A Quote locks you in. Client says yes — WhatsApp, email, cash in hand, doesn't matter — and that's a binding contract under English law. Copper jumps a fifth next week? Trench hits concrete nobody drew on any plan? Your problem now, not theirs. Which is why quotes carry a hard 30-day expiry and an exclusions list with teeth. No exclusions, no protection.
Bids and tenders live in a different world: councils, main contractors, FM companies. JCT Minor Works paperwork, NEC clauses, RAMS documents, method statements, submission portals with 2pm Friday deadlines. Chasing five-figure school maintenance deals means beating four other firms on paper, not on charm.
A Proposal wins the £20k kitchen without racing to the bottom. Same itemised numbers, wrapped in everything that makes a stranger trust you: the £5M liability cert, Gas Safe or NICEIC numbers, five photos of last month's near-identical job, reviews they can click. Turns a frightening number into an easy yes.
Scrawling 'Bathroom refurb — £7,500' on the back of an envelope looks shoddy. It invites people to chip away at your price, and guarantees an argument when the final bill lands. On the flip side, burying a homeowner under thirty pages of small print scares them into the arms of the next builder. You want crystal clarity without the legal bloat.
Put your credentials right at the top. Business name, yard address, phone, email, and whether you are VAT-registered. If you have got badges — Gas Safe, NICEIC, Federation of Master Builders, or TrustMark — stick the registration numbers up there. Tag the site address, give the estimate a reference code like EST-2026-104, and date it clearly with a thirty-day cutoff.
Divide the work into real-world stages. Do not dump forty jobs into one giant paragraph. Split it by how you actually build: ripping out and structural steel, first-fix pipes and cables, boarding and plastering, then second-fix fittings and snagging.
Show labour, gear, plant hire, and skips on separate lines. People know tradesmen charge £250 to £320 a day for skilled graft. What rattles them is seeing a random £6,000 lump sum with zero explanation. If the job calls for a 1.5-tonne mini digger or an eight-yard skip, put the hire cost down in plain numbers.
Drop in provisional sums for items the customer has not decided on yet. If they are torn between cheap ceramic tiles or high-end porcelain, put down an £800 allowance for tiles and adhesive. That keeps your total realistic without locking you into buying expensive slabs out of your own pocket.
Your exclusions list saves your skin when things get awkward. Spell out what is not included: no council building notice fees, no structural engineer calculations, no asbestos testing, no making good rotten floor timbers under old baths, no painting once the plaster dries.
Spell out the payment stages so you are never financing someone else's house on your merchant account. A 25% booking deposit locks their week in your diary and pays for early materials. Stage payments follow as walls go up and pipes go in, with the last 20% due when you sweep the floor and hand over the keys.

Template 4: Roofing (Valley Leadwork & Slate Overhaul)
Apex Pinnacle Roofing | Sheffield S8 | Tel: 0114 278 1190 | NFRC #48102
Estimate EST-2026-419 | Date: 16 Sep 2026 | Valid 30 Days
Client: Patricia Clark | 34 Montgomery Road, Nether Edge, Sheffield S7
Project: Roof Valley Replacement & Slate Repair
Access first — £650 gets the 3-lift tower up on the front elevation, handrails and gate included, delivered, inspected, and taken away after. Then the valley itself — £1,500: five courses of slate stripped each side of the 6m run, split lead out, 18mm marine ply boards down with breathable membrane, new Code 4 lead dressed in stepped sections on copper clips. Two days of leadwork (£980); lead, timber, membrane and clips (£520).

Estimate EST-2026-550 | Date: 16 Sep 2026 | Valid 30 Days
Client: David Lewis | 15 St Peter Avenue, Caversham, Reading RG4
Project: 45m² Vitrified Porcelain Patio & Drainage
Groundwork eats the first £2,380: lawn and old slab dug out 150mm with the 1.5-tonner, 18 tonnes of soil away on a grab, weed membrane down, 100mm of Type 1 compacted dead level with the plate. Machine, driver time and muck-away (£1,400); stone, grab load and membrane (£980). Then the pretty bit — £4,350: 45m² of 20mm vitrified porcelain on a full wet bed with SBR slurry primer, 6m of ACO channel running to a soakaway, joints pointed in brush-in resin. Two pavers, four days (£2,200); porcelain, sand, cement, slurry and resin (£2,150).
Reckoning: £1,400 plant and muck-away, £2,200 labour, £3,130 materials. £6,730 net, £1,346 VAT — £8,076. Worth reading twice against the merchant ticket before it goes anywhere — one typo here costs real money. £1,615.20 (20%) books the slot, £3,230.40 when the sub-base is compacted, £3,230.40 on the finished patio. Turfing, planting, stump grinding and fencing all sit outside this price — happy to quote them separately.
Template 6: Painting & Decorating (Exterior Masonry & Windows)
Prestige Decorating Ltd | Harrogate HG1 | Tel: 01423 884010 | PDA #10482
Estimate EST-2026-614 | Date: 16 Sep 2026 | Valid 30 Days
Client: Marcus Vance | 8 Crescent Gardens, Harrogate HG1
Project: Exterior Masonry, Windows & Front Door
Prep comes first at £545 — and anyone who's skipped prep knows why it matters. Render jet-washed back to clean, flaking paint scraped to hard edges, hairline cracks filled. Two decorators for the day (£450); fungicidal wash, fillers and abrasives (£95). Then the coating itself, £1,690: two coats of Dulux Weathershield smooth on the render, six timber sashes sanded, primed and satined in Zinsser exterior, hardwood front door rubbed down and glossed. Three decorator-days (£1,350); paint, primer and enamel (£340).
So that's £1,800 labour and £435 materials. £2,235 net, £447 VAT — £2,682 total. £670.50 (25%) to book, £2,011.50 on the walk-round sign-off. Glazing repairs and rotten sill replacements aren't in this price — flag them now and I'll add them properly.
Template 7: Handyman & Property Maintenance (Domestic Snagging List)
Reliable Property Services | Nottingham NG2 | Tel: 0115 922 4110 | Non-VAT
Estimate EST-2026-788 | Date: 16 Sep 2026 | Valid 30 Days
Client: Sophie Bennett | 21 Burlington Road, Nottingham NG5
Project: Remedial Domestic Snagging List
The list itself, as it'd read on the job sheet: seized basin waste out, new one in, resealed in anti-mould silicone (an hour). Sticking fire door planed true with a fresh mortice latch (hour and a quarter). Three cracked splashback tiles out, new ones in, perimeter re-grouted (hour and a half). Loose carpet threshold screwed back into the concrete subfloor (half hour). Wobbly balustrade spindle secured and filled (three quarters).
Five hours at £50 comes to £250 labour; brass waste, silicone, latch and grout come to £65. £315 total, no VAT registered. £157.50 books it, £157.50 on completion. One caveat: matching kitchen tiles are down to you — supply spares and I'll fit them.
Ask any busy builder what actually wins work and it isn't the shiniest van — it's answering first with numbers that make sense. The pattern repeats weekly: ceiling leaking, wall coming down, three WhatsApps sent. Two builders surface Sunday night with apologies. The third had someone asking for wall and fuse-box photos within twenty seconds, estimate range back before lunch. Guess who gets the deposit tap while the others are still typing.
Here is how that conversation runs inside WhatsApp:
Customer: 'Hi Dave, looking for a price to knock down the internal wall between our kitchen and dining room in Guildford. Solid brick wall, 3.8m wide. Got structural calcs already.'
Susan (on behalf of Dave): 'Hi! Dave is on site right now, but I can pull an estimate together for you. Could you send two photos of the wall from both sides, plus a snap of the engineer's calculation sheet? Are there any radiator pipes or electrical sockets on it?'
Customer: [Sends 3 photos] 'Here are the photos. One double socket and a light switch on the kitchen side, no radiators. Postcode is GU2.'
Susan: 'Brilliant, that gives Dave what he needs. Based on his standard rates and your 203x133 steel spec, here is our rough breakdown:
• Prep, Acrow props, and wall demolition: £1,220
• Supplying, hoisting steel beam, padstones & fireproofing: £1,790
• Plaster skim finish, floor screed, and 8-yard skip: £1,130
• Net Estimate Range: £4,140 – £4,600 + VAT
Dave can pop by for a 15-minute padstone check on Thursday at 4:30pm. Would that suit?'
Customer: 'Spot on, right in our budget. Thursday at 4:30pm works great.'
By the time other builders open their laptops on Sunday night, the job is already surveyed, priced, and booked.
You do not need complicated software or hours at a keyboard to stop working unpaid overtime. Here is how modern contractors set up their quoting on autopilot:
First, hook up your rate card. Feed Susan your daily bench rates — £280 for a skilled tradesman, £160 for an improver, twenty percent on materials, eight-yard skip allowances, standard callout minimums. Connect Xero, QuickBooks, Tradify, or Jobber so line items and invoices flow across with no double-handling.
Second, let WhatsApp triage jobs while your hands are on the tools. A lead arrives through Checkatrade, Rated People, or your website form at 11am while you are fitting a radiator. Susan replies in four seconds, asks for three photos of the problem, and checks postcodes with missed-call text-back. Or if you are standing in front of the job yourself, just drop Susan a voice note: 'Dave at 14 Moor Lane, consumer unit change, 18-way board, SPD, 4 circuits, two days, test cert, 30% down.' Susan turns your raw spoken notes into an itemized estimate before you have even walked back to the van.
Third, bank the booking deposit over Apple Pay. The customer opens an itemized summary right in WhatsApp alongside a Stripe payment link. They tap the link, authorise the deposit with their thumbprint, and the job gets inked into your calendar. No waiting for bank transfers, no typing out sixteen-digit card numbers, no awkward phone calls.
Compare how the three quoting options play out when you are slammed with work:
The kitchen-table Excel spreadsheet is free, but it drains eight to twelve hours of your evenings every week. You type out line items when your eyes are heavy, guess merchant prices from memory, and send out PDFs three days late after the lead has gone lukewarm. Close rates hover around 30% simply because you took too long.
Desktop trade software like Jobber, Tradify, or ServiceM8 gives you cleaner templates, but you still have to sit at a keyboard, click through twenty input boxes, and manually add customer records. It cuts down admin slightly, but it does not solve the speed problem when you are up a ladder or under a floor.
Susan on WhatsApp skips the laptop altogether. Leads get greeted in four seconds, photos and video walk-throughs get triaged on the spot, and an itemized quote goes out before the customer can ring anyone else. Close rates push past 75% because homeowners hire the first contractor who looks organized and replies immediately.
Two things bleed trade profits faster than anything else: scope creep and wholesale material price jumps.
Every builder knows the routine. You are four days into a bathroom rip-out when the client leans against the doorframe: 'Dave, while you are here with the floor up, could you just run new pipes into the cupboard, box in that soil stack, and swap out the radiator for a heated towel rail?'
You nod, say 'No worries, I will sort it,' and get on with the job. At the end of the project, you add £650 for extra copper, fittings, and labour to the invoice. The client goes pale: 'I thought that was part of the original price!' Now you are arguing in their hallway over money you worked hard to earn.
Kill the argument before you lift a spanner with a 60-second WhatsApp Variation Order. When they ask for extra work on site, send a voice note: 'Susan, variation order for Mrs Smith: towel rail install, pipework alteration, chrome valves, £220 labour, £110 parts, plus VAT. Send for approval.' Susan shoots a three-line summary straight to the client phone. They tap 'Approve' in WhatsApp, and the extra cost automatically appends to their final invoice. Total paper trail, zero friction, dignity intact.
The second trap is merchant price inflation. If you quote a job in March based on copper and timber prices, and the customer rings you back in August to book the job, your profit is gone. Put a hard 30-day price lock on your paperwork: 'All prices reflect merchant costs on the date of this estimate and are guaranteed for 30 calendar days. Jobs booked after 30 days will be re-priced against current trade counter prices.'
Frequently Asked Questions (FAQ)
What is the legal difference between an estimate and a quote in the UK?
An estimate is an educated rough guide (+/- 15% to 20%) based on visible site conditions, allowing you to re-price hidden problems like rotten joists or obsolete wiring. A quote is a fixed, legally binding contract. Once a client accepts your quote, you are contractually locked into that number even if timber prices double or the job takes two extra days.
How fast should I get an estimate out after looking at a job?
Within twenty-four hours at the absolute latest, but ideally within four hours. Almost four out of five trade contracts (78%) go to whoever hands over an itemized, professional number first. If you leave it until your Sunday evening paperwork session, your competitor has already sent an estimate, taken a deposit, and put them in the diary.
How much deposit can I ask for upfront?
For residential work, 20% to 30% is standard practice to cover upfront material orders and reserve calendar dates. On large structural projects or custom joinery requiring bespoke fabrication, taking 40% to 50% upfront is entirely reasonable. Never start work or purchase bespoke materials without a cleared deposit.
Can I charge homeowners for quoting a job?
Free estimates remain the industry expectation across domestic trades. But for complex diagnostic work — such as tracing hidden leaks under floorboards, thermal imaging, or CCTV drain surveys — professional contractors charge a standard diagnostic callout fee (typically £75 to £150) which is credited against the repair work if the client proceeds.
How can I quote jobs from my van without sitting at a laptop?
Modern sole traders use WhatsApp AI tools like Susan. You take three photos of the job, send a 20-second voice note listing materials and days, and Susan builds an itemized, branded PDF estimate in seconds, complete with a 1-tap card link so the customer can pay your deposit directly from WhatsApp.
