Who gets the lead, price, contract and bad-lead terms, as each one publishes them

How is each lead checked?

What does each supplier offer?
AceLeads
A UK lead marketplace with a page for home extension leads: single storey, side return, wraparound and double storey. It's aimed at design-and-build firms, main contractors and builders, architects with build arms and specialist extension firms.
Each lead confirms the enquirer owns the property, and includes the extension type, the rough floor area, the planning stage, whether an architect is already engaged, a budget band, the intended start, the property type and age, and the postcode. You can set the budgets and floor areas you work at, and filter by postcode area. Exclusive leads go to you alone. Shared leads go to a small number of contractors and cost less. Leads appear in its buyer portal, with email and in-app alerts.
You aren't charged per enquiry. You pay a joining or setup fee, depending on the plan, then a share of the work you win, agreed in writing before you start. Neither figure is published. On its Founding Partner plan your area is exclusive, you fund the ad budget monthly in advance, and there's a minimum period. Its Lead Partner plan has no long contract. A lead that genuinely fails its criteria is replaced.
Adfluential
Generates leads in the UK and the US, with a page for UK extension and conversion leads: homeowners planning extensions, garage conversions, loft conversions and extra living space. Leads come from websites and campaigns it owns and manages, not shared lists or recycled marketplaces.
Contact details are verified and matched to filters you agree, though it doesn't say how, and leads go into your CRM. There are three ways to buy: a fixed cost per qualified lead, with your team booking the appointments; per lead plus its managed call centre, which books appointments for you; or, for strategic partners, a revenue share paid once the job is completed. It doesn't publish its prices, whether leads are exclusive, its contract terms or what happens to a bad lead.
BestBuilders
A homeowner site with cost guides and quote requests across a range of trades, including extensions, that sells the enquiries it gets to local firms. You get a weekly email of live enquiries in your trade and area, with the job details shown and the contact details withheld until you pay.
Each lead is sold first come, first served, to a small number of firms at most. It includes the homeowner's name, phone number, email, postcode and what they told it about the job. Leads cost typically £5–£20, depending on the trade, with extensions at the top of that range. Your first lead is free, in return for linking to your profile from your website. There's no membership fee, minimum spend or contract, and its trade page says there's no subscription or minimum term during its launch phase. It doesn't publish what happens to a bad lead.
LeadsDoWork
Runs leads.work, which sells house extension enquiries to builders across the UK, alongside loft, garage and basement conversions and other trades. It says the enquiries come from a network of over 300 home improvement websites, blogs and related content, and arrive by app, SMS or email. Its checks before a lead is approved can include phone, SMS and visual checks.
Leads are shared: you compete with 1 to 3 other trades for the same job, and no more than 5 compete for any one job. On Connect, its pay-per-lead plan, a house extension lead costs £54, plus a weekly service fee of £11, excluding VAT. You set a weekly quota, which isn't guaranteed, and you can cancel any time. A refund request is reviewed within three business days and, if approved, credited to your balance.
It also sells Smart Local packs. The large building works pack, which includes house extensions, costs £67.20 for 5 leads, £117.60 for 10 and £205.20 for 20, excluding VAT. Leads in a pack can't be returned individually, and a pack you've started runs until it's delivered.
POCKLA
This is usFinds homeowners planning a single or double storey extension (rear, side, side return or wraparound), follows up on WhatsApp or by text, and sends each lead to your CRM or POCKLA Desk.
Every lead is sold once, to one buyer, and invalid numbers are returned with no time limit. It publishes an indicative £100–£300 per qualified web lead, with the exact price agreed on a call. The phone number is checked live and the postcode against your area. Everything else is the homeowner's own answers on the form: the property, the extension they want and its rough size, where they are with drawings and planning, their budget and their timeframe. You choose the postcodes, and it doesn't send commercial projects, finance-dependent jobs or duplicates. It checks Federation of Master Builders or TrustMark membership before launch if you advertise it, and also does live transfers, priced on your criteria. There's no setup fee, no monthly fee and no minimum term.
ROI Leads
Sells home extension enquiries to builders, one builder per area. It covers single-storey rear, two-storey, side return, wraparound, over-garage, and garden room and studio extensions. It funds and runs all the advertising, and works city by city, with Birmingham, Bristol, Cardiff, Leeds, London and Manchester among its live areas.
It says the homeowner should have planning permission or confirmation that the project falls within permitted development, and it doesn't send enquiries where the planning position is genuinely unclear. The build type, rough size and start window are established first. There's nothing to pay up front: you pay a share of the contract value on work that completes, as a percentage of the final contract value agreed before your first enquiry. The percentage isn't published, and neither are its contract or bad-lead terms.
Which home extension lead suppliers are exclusive?
Two sell every extension lead to one buyer: POCKLA, and ROI Leads, which sends each enquiry to one builder per area.
At the others, it depends:
- AceLeads sells exclusive leads, routed to you alone, and shared leads, which go to a small number of contractors and cost less.
- BestBuilders sells each lead first come, first served, to a small number of firms at most.
- LeadsDoWork says you compete with 1 to 3 other trades for a job, and never more than 5.
- Adfluential doesn't say.
A shared lead isn't a worse version of an exclusive one, just a different product. Our guide to exclusive vs shared leads explains the difference.
How much do home extension leads cost?
Three suppliers here publish a price. BestBuilders puts a lead at typically £5–£20, depending on the trade, with extensions at the top of that range. LeadsDoWork charges £54 a house extension lead on Connect, plus an £11 weekly service fee, or £67.20 to £205.20 for a Smart Local pack of 5 to 20 large building works leads, all excluding VAT. POCKLA publishes an indicative £100–£300 per qualified web lead.
AceLeads and ROI Leads don't charge per lead. ROI Leads takes an agreed percentage of the final contract value on work that completes, with nothing up front. AceLeads charges a joining or setup fee, then a share of the work you win. Neither publishes its percentage. Adfluential doesn't publish prices.
The price depends on your area, your criteria, the volume and whether the lead is exclusive. A shared enquiry, an exclusive lead and a share of a signed contract aren't three prices for the same thing, so work out what each would cost you per job won. Our guide to cost per lead vs cost per job shows how.
What about Checkatrade, Rated People and Bark?
Marketplaces work the other way round. Homeowners post a job, and trades pay to be put in touch, usually alongside other trades.
Checkatrade is a trades directory. Its plans for trades are £0, £30 a month and from £59 a month, and the plans from £59 add customer enquiries. Fixed plans run for 12 months. Source: pricing.
Rated People is now part of Checkatrade Group, and every job posted there is matched with a trade from Checkatrade's network. On its Opportunities Board, creating an account is free and you pay only when you choose to unlock a lead. Its fixed lead plan is priced on your trade and area, and runs on a 12-month term. Sources: help for trades, Checkatrade Group.
On Bark, professionals pay in credits to respond to a request, and a general request can go to up to five professionals. The credit cost is shown before you buy, with VAT on top, and credits last three months. Credits are returned for some bad contacts, such as an invalid phone number, reported within seven days. Sources: terms, seller pricing.
What about agencies that run a campaign for you?
Some companies sell a campaign rather than individual leads, so we've left them out of the tables. Leads Everyday has a page for house extension builders, covering single-storey rear, double-storey, wraparound and garage conversion work. It builds a landing page for your business and runs Google Ads to it, and the leads are sent to your phone and never shared with competitors. It takes no commission on jobs.
Its terms charge a flat monthly fee agreed at your consultation, with your Google Ads spend paid separately, straight to Google. The extension page says there are no long-term contracts. The terms set an initial minimum of two months from the date your campaign goes live, then 30 days' written notice. Sources: house extension leads, terms.
What to ask before you buy home extension leads
- Who else gets the lead? One builder, a few, or up to five, and whether your area is yours alone.
- What exactly am I buying? A shared enquiry, an exclusive web lead, a booked appointment, or a campaign run in your name.
- What's the job? Single or double storey, rear, side return or wraparound, and roughly how big. Some suppliers mix in loft, garage and basement conversions, so ask whether you can filter them out.
- How far has it got with drawings and planning? No drawings yet, drawings done, applied or approved. Ask whether that's the homeowner's own answer or something the supplier has checked.
- What's the budget, and whose figure is it? Ask whether you can set a minimum budget or floor area, so smaller jobs don't reach you.
- How am I charged? Per lead, a pack, a weekly fee, a monthly fee or a share of the contract. If it's a share, ask how it's worked out, when it's due and whether stage payments change it.
- What counts as a bad lead, and what ties me in? The window to report one, minimum periods, notice and any ad budget you fund yourself.

How we checked
We started from the suppliers that come up when you ask search engines and AI assistants who sells home extension leads in the UK. We left out any that don't advertise extension leads, and covered agencies that run a campaign for a monthly fee separately. Then we read each supplier's own website on 29 October 2026: its extension page, plus its pricing, terms and FAQ pages where we used them. We didn't ask for quotes or contact any supplier. Prices and terms change, so check them with the supplier before you buy.
If you run one of these companies and something here is wrong or out of date, email team@pockla.com and we'll correct it.
