Your own London list of builders
General builders take on extensions, renovations and repairs, often managing subcontractors for each trade. The owner usually quotes, orders materials and chases payments, so anything that tightens cash flow or reduces admin gets attention.
Working builders in London goes faster with one clean file for the city and a segment per neighbourhood or nearby town such as Kitchener, Hamilton and Mississauga. Status and tags show who is new, contacted or already a customer.
Most sellers work from a bought list that everyone else has too. A list of builders in London that you built yourself is the one nobody else is emailing yet.
Build your London list of builders in four steps
You check every step before anything is saved or sent.
Collect builders in London
Export builders in London from Google Maps listings or online trade directories as CSV, or paste the results page into paste and collect.

Import into one lead file
Drop the file into a lead file called Builders London. Columns are matched for you and duplicates are flagged before anything is saved.

Fill in the missing emails
No email in the export? Tick info@, office@, enquiries@ and admin@ and addresses are derived from each website.

Reach them in small batches
Pick the segment, keep only status New, write one mail with placeholders like {company|your team} and send it in small batches.

Fields worth recording for builders in London
Any column in your import can become a field. These are the ones worth keeping for builders.
| Field | Why it helps |
|---|---|
| Company name | The key field. Duplicates are checked on it or on the website. |
| Website | Needed to derive an email when the export has none. |
| Project types | Extensions, lofts and full renovations need different suppliers. |
| Uses subcontractors | Tells you whether they need tools to manage other trades. |
| Typical job size | Helps you judge whether your offer fits their budget. |
| Service area | Merchants and hire firms work within a delivery radius. |
| Accreditations | Membership of a trade body hints at size and professionalism. |
What slows down prospecting builders, and the fix
Builder lists overlap with every other trade, so it is hard to tell who is a real general builder.
Add a Project types field and tags, then put the records you have checked in their own segment so campaigns only reach the right firms.
You collect builders from several towns in separate files.
Import all of them into one lead file with a Service area field; duplicates across files are flagged before you publish.
Builders who said not now are forgotten until a competitor wins them.
Set a status and a tag like follow up in spring, and save a filter on that tag so the list is ready when the time comes.
Angles that get builders to reply
Write one mail with placeholders and let the details change per record. These openings tend to work with builders.
- Lead with getting paid faster and cleaner paperwork, because late payments hurt small builders most.
- Talk about reliable delivery to site, since a missed delivery can hold up a whole team.
- Offer help winning better jobs, such as a stronger website with past project photos.

Read moreEmailing builders in Canada
In Canada, commercial email falls under Canada's Anti-Spam Legislation (CASL), which is stricter than most and generally requires express or implied consent before you send. Implied consent only applies in limited cases, for example when someone has conspicuously published their business email address without saying they do not want messages and your message is relevant to their role. Every message must identify you, include your contact details and offer an unsubscribe option that works. This is general information, not legal advice.
Builders are often easiest to reach first thing in the morning or at the end of the day. Many plan work for the year in winter, which can be a good time for new suppliers. Read the deliverability guide before your first send.
Questions people ask
Yes. Put London in its own segment, or keep a City field and save a filter such as city contains London. You always see which part of the market you already worked.
If your file has an email column, that wins. If it only has websites, tick the prefixes you want, such as info@, office@, enquiries@ and admin@, and Riftjaw derives addresses from each domain. Derived addresses are good guesses, not verified, so start with small batches.
No. Riftjaw is not a data vendor. You collect the builders yourself from public sources or your own files and import them. That is why the list is yours and why there is no credit meter on it.
Where planning records are public and list the agent or builder, you can collect them yourself and import them. Riftjaw does not crawl those sites for you, but it handles the file you bring.
Pick a key field such as website or email in your lead file. Riftjaw flags duplicates in the file and against existing records before anything is pushed.
