Before you contact anyone
Five minutes of prep makes every conversation faster and stops you accepting a quote that's missing things.
- Describe the job in one paragraph. What's the problem, where in the property, when did it start. A few photos help.
- Decide your rough budget. Honest range, not a target. Three quotes will tell you if it's realistic.
- Know how urgent it is. Burst pipe is now; bathroom refurb can wait three weeks for a good trade.
- Shortlist two or three. The shortlist feature on this site is built for exactly this — save businesses you want to hear from, then call them in order.
Questions to ask when you call
Treat the first call like an interview. A good tradesperson expects these questions; one who bristles at them is a red flag.
- "Are you insured?" Public liability cover of at least £1 million is standard. Some larger jobs need £2-5m.
- "Are you registered with the relevant body?" Gas Safe for any gas work (it's a legal requirement). NICEIC, SELECT or NAPIT for electrical. OFTEC for oil. RECC for renewables. No registration, no job — especially for gas.
- "How long have you been trading and at this address?" Five-plus years at a fixed address is reassuring. New trades aren't automatically worse but the safety net is smaller.
- "Can I see examples of similar work or speak to a recent customer?" A reputable trade will have both.
- "When can you start and how long will it take?" Vague answers ("a couple of weeks", "shouldn't take long") leave you exposed. Push for specifics.
- "What guarantee or warranty do you offer?" Workmanship guarantees of 1-12 months are typical; longer is better.
What a proper written quote includes
A verbal "around £2,000" isn't a quote — it's a guess. Get every quote in writing (email is fine) before any money changes hands. It should cover:
- Scope of work, in plain English — what they're doing and what they're not
- Itemised cost — labour vs materials, ideally with daily rate visible
- VAT shown separately (legal requirement if they're VAT-registered)
- Start date and target completion date
- Payment schedule — what's due when
- What happens to waste / making good after
- Warranty length and what it covers
- Quote validity period (most are 30 days)
Be wary if one quote is dramatically lower than the others. It usually means they've skipped something — materials, scaffolding, waste removal, second visits to finish. Ask what's not included.
Deposits and payment
- A deposit for materials is reasonable — typically 10-30% if the trade is buying expensive items (boilers, kitchens, slates). Over 50% upfront is a flag.
- Never pay 100% upfront. Once they have the money, your leverage is gone.
- Stage payments on bigger jobs. Pay after each visible milestone: materials delivered, first fix complete, second fix complete, snagging signed off.
- Pay by bank transfer or card, not cash. Cash leaves no paper trail and is sometimes a sign of off-the-books work (no warranty, no recourse).
- Get a receipt for every payment. Email confirmation is fine.
Red flags — walk away
- Cash only / refuses to give a written quote / no email address
- Pressure to decide today, sign now, pay now
- No fixed business address — just a mobile number
- Quote dramatically lower than competitors with no explanation
- Cannot provide proof of insurance or registration
- Reluctant to share recent customer references
- Showed up unannounced and "noticed your roof needs work" — classic doorstep approach
- For gas work: not on the Gas Safe Register. Stop the conversation — it's illegal for them to do gas work in your home.
After the work is done
- Walk through with the trade. Open every door, run every tap, switch every light. Snag anything off.
- Get the paperwork. Gas Safety Certificate for any gas work. Electrical installation certificate (EIC) for new wiring. Roofing warranty cards. Boiler registration.
- Pay the final balance only after you're satisfied. If there are snags, withhold the proportionate balance until they're fixed.
- Leave an honest Google review. Detailed, specific feedback (job done, timeline, cost, quality) helps the next person — and helps us refresh the rankings.
If something goes wrong
- Talk to the trade first, in writing. Most reputable trades will come back and put it right. Email is better than phone because it creates a record.
- If they won't engage, your route depends on the issue:
- Gas: report to the Gas Safe Register (gassaferegister.co.uk). They investigate unregistered work and bad practice.
- Electrical: contact NICEIC, SELECT or NAPIT depending on who certified them.
- General workmanship / contract dispute: Trading Standards Scotland (advice.scot) and the Consumer Rights Act 2015 — work must be of satisfactory quality, carried out with reasonable care and skill, and finished within a reasonable time.
- Card / finance disputes: if you paid by credit card and the bill is between £100 and £30,000, Section 75 of the Consumer Credit Act gives you a route to claim back from your card provider.
- Small Claims Court (Simple Procedure in Scotland) handles disputes up to £5,000. The forms are user-friendly and don't usually need a solicitor.
