We've written this policy to be straightforward and readable, not to bury you in legalese. We take privacy seriously — but we also think you deserve to actually understand what you're reading. If you have any questions at all, email us at [email protected] and we'll answer plainly.

N4 Gas Limited is the data controller for information collected through and in connection with www.n4gas.co.uk. We are responsible for deciding what, why and how data is used, and for keeping it safe.
We are gas heating engineers based in North London. Gas is all we do — and handling your data with the same care we bring to our engineering work is something we take seriously.
This policy explains how N4 Gas Limited collects, uses and protects data in connection with our main public website at www.n4gas.co.uk. It covers:
This policy does not cover our full client data practices. If you are an existing client, a landlord with an account, or a tenant of one of our clients that has a relationship with us then you should be aware that additional privacy information applies. Please see Section 6 for details of where to find it.
We do not use advertising cookies, tracking pixels, or any technology designed to follow you across the internet or build a profile of your browsing behaviour. We are not in the business of selling data or monetising your visit to our website.
We do not use advertising or cross-site tracking technologies on www.n4gas.co.uk. No retargeting, no ad networks, no behavioural profiling.
Our website may place small cookies on your device that are strictly necessary for the site to function correctly. These cookies do not identify you personally and are not used for any marketing purpose. Examples include session management and security tokens that prevent cross-site request forgery.
We may review anonymised, aggregated data about how our website is used — for example, which pages are most visited, how long pages take to load, or where in a journey users tend to leave. This data cannot be used to identify you as an individual. We use it only to improve the website.
Any performance analytics tools we use are configured to anonymise IP addresses and not share data with third parties for their own purposes.
| Type of technology | Do we use it? | Purpose |
|---|---|---|
| Strictly necessary cookies | Yes | Site functionality and security |
| Anonymised performance analytics | Possibly | Improving website performance — cannot identify you |
| Advertising / retargeting cookies | No | Not used |
| Cross-site tracking / profiling | No | Not used |
| Social media tracking pixels | No | Not used |
To keep our website secure, reliable and available, we use third-party services for functions such as:
These services may, in the course of carrying out their functions, collect or process anonymised information about visitors — such as IP addresses (which may be anonymised or masked), request types and response times. This is incidental to their operation and is not used by us to identify individuals.
Where third-party providers process any data on our behalf, we ensure they do so under appropriate data processing agreements and in accordance with UK data protection law. These providers act as data processors, not data controllers — they do not use data from our website for their own purposes.
We do not embed third-party social media feeds, advertising networks or tracking scripts into our main website pages.
If you contact us through the website — whether by submitting a contact form, sending an email via a mailto link, or any other communication channel provided on the site — we will receive and process the information you provide. This will typically include your name, contact details and the content of your message or enquiry.
We use the information you send us to:
We do not add you to marketing lists or pass your details to third parties for marketing purposes on the basis of a contact form submission alone.
We may retain a record of contact and conversations for up to six (6) years from the date of the last communication. This retention period reflects standard business practice for record-keeping and is consistent with the limitation period for civil claims under UK law. After this period, records are securely deleted.
If your enquiry results in us carrying out work for you, the retention of associated data is governed by our full client data protection policy — see Section 6.
When you contact us, we process your data on the basis of legitimate interests — specifically, our legitimate interest in being able to respond to enquiries, conduct our business and maintain records of communications. Where work is carried out, the basis shifts to contract performance.
This website privacy policy covers only the public-facing website at www.n4gas.co.uk. If you are an existing client, an account holder, a landlord using our certification or compliance services, or a business with whom we have an ongoing commercial relationship, a more detailed data protection policy applies to how we handle your data in that context.
This full policy — covering client records, certification data, works order history, payment records and more — is available through our secure client portal, the N4 Gas Access panel.
Our comprehensive data protection policy for clients and account holders — covering all data we hold in connection with your engagement with us — is published in the N4 Gas Access panel. If you are a client, landlord account holder or business with whom we have a relationship, please refer to this document for the full picture of how your data is handled.
View full policy at access.n4gas.co.ukIf you have questions about data held in connection with work we have carried out for you, or a commercial account, please contact us directly at [email protected] in the first instance and we will direct you appropriately.
Under UK data protection law (the UK GDPR and the Data Protection Act 2018), you have a number of rights in relation to your personal data. These are set out below in plain English:
You can ask us what personal data we hold about you and receive a copy of it.
If data we hold about you is inaccurate or incomplete, you can ask us to correct it.
In certain circumstances you can ask us to delete data we hold about you.
You can object to our processing of your data where we rely on legitimate interests.
You can ask us to restrict how we use your data in certain circumstances.
Where applicable, you can request your data in a structured, machine-readable format.
To exercise any of these rights, please contact us by email. We aim to respond to all data rights requests within one calendar month of receipt. There is no charge for making a request.
Please include your name, contact details and a clear description of what you are requesting. We may need to verify your identity before processing the request.
| Type of data | Retention period | Reason |
|---|---|---|
| Website contact / enquiry records | Up to 6 years | Standard business record-keeping; civil limitation period |
| Anonymised website analytics | As configured (typically 26 months or less) | Performance monitoring only; cannot identify individuals |
| Security logs (third-party) | As determined by third-party provider policy | Security and uptime monitoring |
| Client and works records | Governed by full client policy | See access.n4gas.co.uk |
When data is no longer required, it is securely deleted or anonymised in a manner that prevents recovery.
We take reasonable technical and organisational steps to protect personal data against accidental loss, unauthorised access, disclosure or destruction. These include:
No system can guarantee absolute security, and we cannot warrant that data transmitted over the internet will always be perfectly secure. However, we take our obligations seriously and maintain appropriate safeguards.
In the unlikely event of a data breach that is likely to result in a risk to individuals' rights and freedoms, we will notify the Information Commissioner's Office (ICO) within 72 hours of becoming aware of it, and affected individuals where required by law.
We may update this privacy policy from time to time — for example if we change how the website works, if legislation changes, or if we begin using new third-party services. When we do, we will update the version number and the "last reviewed" date at the top of this page.
We encourage you to check this page periodically if you use our website regularly. We will not notify you of minor clarifications, but any material changes will be noted clearly at the top of the page for a reasonable period.
Continued use of the website following a policy update constitutes your acknowledgement that the updated policy applies.
If you have any questions about this privacy policy, want to understand how your data is being used, or wish to exercise any of your rights, please get in touch:
We hope to resolve any concerns about data use quickly and directly. However, if you are not satisfied with our response, you have the right to lodge a complaint with the UK's data protection regulator:
