North London Trades Guide (northlondontradesguide.co.uk)
Last updated: 24 October 2026.
1. Who we are
North London Trades Guide is a free online guide to plumbing, heating and electrical firms in Islington, Camden and Haringey. It is published by Tufnell House Ltd, a private limited company registered in England and Wales, company number 17520029, registered office 178 Junction Road, London N19 5QQ ("we", "us").
Tufnell House Ltd is the data controller for the personal data described in this notice. Contact: [email protected].
We are a directory and referral service. We do not carry out plumbing, heating or electrical work ourselves. The firm you choose does the work and is responsible for it.
2. What we collect and why
| What | When | Why (purpose) | Lawful basis (UK GDPR Article 6) | How long we keep it |
|---|---|---|---|---|
| Website visit statistics (pages viewed, rough location by country, browser type) | Every visit | To see which pages are useful | Legitimate interests (running and improving the site) | Aggregated only. We use Cloudflare Web Analytics, which does not set cookies or build profiles of individual visitors |
| Outbound click records (which listing was clicked, time, referring page, browser type, a flag for automated traffic) | When you click "Visit website" or "Call" on a listing | To count how many people the guide sends to each firm, and to filter out bots | Legitimate interests | 24 months, then deleted. No name, email or IP address is stored in this record |
| Phone calls to a tracked Featured partner number (your phone number, time, length of call, and a recording of the call) | Only if you call a number shown in a "Featured partner (paid)" box | To connect you to that firm, confirm the call was referred by us, check service quality and handle complaints or disputes | Legitimate interests. You are told at the start of the call that it may be recorded and who it is connecting you to | Call records 24 months. Recordings 90 days, then deleted, unless needed for a live complaint or legal claim |
| Quote request form details (name, phone, email, postcode, description of the job) | Only if you fill in a quote form on a Featured partner box | To pass your request to that one named firm so it can contact you and quote | Steps at your request before a contract (Art 6(1)(b)) and legitimate interests | 12 months, then deleted |
| Messages to us (claims, corrections, complaints) | When you email us | To answer you and keep listings accurate | Legitimate interests | 24 months after the matter closes |
| Business listing data (firm name, services, areas, business phone, website, published registration numbers, Companies House details) | When we build the guide | To publish an accurate directory | Legitimate interests | While the firm trades and is listed. Sole traders can ask us to remove their listing at any time |
We do not collect special category data. Please do not include health or other sensitive details in a quote request.
3. Who we share it with
- The firm you choose, and only that firm. If you call a Featured partner number or send a quote request from a Featured partner box, your call is connected to, and your details are sent to, the one firm named in that box. We never sell your details, never pass them to other firms, and never put them on a shared lead marketplace.
- Our service providers, who process data only on our instructions: Cloudflare, Inc. (website hosting, analytics and the database for click and form records) and Twilio Ireland Limited or a similar UK call tracking provider (phone numbers, call routing and recordings). Some of these providers may process data outside the UK under the UK International Data Transfer Agreement or the UK Extension to the EU US Data Privacy Framework.
- Authorities, if the law requires it.
4. Call recording
Calls to a tracked Featured partner number may be recorded. Before you are connected, a short message says that the call is from North London Trades Guide, that it may be recorded, and the name of the firm you are being connected to. If you do not want a recorded call, hang up and use the firm's own website or main number shown on its listing page, which is not tracked by us.
5. Your rights
You have the right to ask for a copy of your data, to have it corrected or deleted, to object to our use of it, and to restrict its use. Email [email protected]. We reply within one month.
If you are unhappy with how we handle your data you can complain to the Information Commissioner's Office, ico.org.uk, 0303 123 1113.
6. Cookies
The guide does not use advertising or tracking cookies. Cloudflare Web Analytics is cookieless. If this changes we will ask for your consent first.
7. Changes
We will post any changes on this page with a new date.
