Gas Safe and Compliance Apps
Gas Safe Register App

- Access your Gas Safe ID card digitally
- Check the Gas Safe status of other engineers
- Access technical guidance and notices
- Stay up to date with gas safety regulations
Free to download for all Gas Safe registered engineers.
Corgi HomePlan App
For plumbers who carry out boiler servicing and maintenance contracts, the Corgi HomePlan app helps manage ongoing service agreements and customer records.
Boiler and Heating Apps
Worcester Bosch App
The Worcester Bosch app is useful for plumbers who regularly install and service Worcester Bosch boilers. It provides technical documentation, installation guides, and fault finding support — all accessible on site from your phone.
Vaillant App
Similar to the Worcester Bosch app, Vaillant’s trade app provides technical support, installation documentation, and warranty registration for Vaillant products.
HHIC Heating Calculator
The Heating and Hotwater Industry Council app provides useful calculators for heat loss, pipe sizing, and system design — handy for specifying systems accurately on site.
Water Regulations and Compliance
WRAS Water Regs App
The Water Regulations Advisory Scheme app gives plumbers quick access to the Water Supply (Water Fittings) Regulations 1999 — essential for ensuring installations are compliant and avoiding enforcement issues.
CIPHE Technical Guidance
For members of the Chartered Institute of Plumbing and Heating Engineering, the CIPHE provides access to technical guidance documents and industry updates through their member portal.
Accounting and Invoicing Apps
Xero
Xero is one of the most widely used accounting tools among UK tradespeople and integrates directly with Tradify. Handles VAT returns, bank reconciliation, and expense tracking — and makes Self Assessment significantly less painful.
QuickBooks
Another strong option for UK plumbers. Integrates with Tradify and most other job management apps and is widely supported by UK accountants.
Communication and Customer Management
WhatsApp Business
Free and already on most phones. WhatsApp Business lets you set up a business profile, create quick reply templates for common messages, and keep your business and personal conversations separate.
Ideal for sending job confirmations, appointment reminders, and following up on quotes.
Google Business Profile
Your Google Business Profile is one of the most powerful free marketing tools available to any UK plumber. Customers searching for a plumber in your area will see your profile first — keep it updated with recent jobs, photos, and customer reviews and it will drive local enquiries consistently.
