Our Repair Approach
RAW Service prioritises precise fault finding to avoid unnecessary part replacements and repeat callouts. Every repair follows a structured diagnostic process designed to identify the root cause quickly and resolve it effectively.
- Systematic diagnostics: full assessment of boiler operation, error codes and component behaviour to pinpoint the exact fault
- Targeted repairs: components are repaired or replaced only where required, avoiding guesswork and unnecessary costs
- System-wide checks: pressure, flow, circulation and controls are reviewed to ensure the issue isn’t part of a wider system fault
- Safety and performance testing: the boiler is tested after repair to confirm safe operation and consistent performance
- Clear, practical guidance: you’ll understand what failed, why it happened, and whether any further action is recommended
This method reduces repeat issues, improves long-term reliability, and ensures the repair is both effective and cost-efficient.

Boiler Services FAQ
How often should I get my boiler serviced?
To ensure your boiler is running safely and efficiently, we recommend an annual service by a Gas Safe registered engineer. Regular servicing can prevent unexpected breakdowns, prolong the life of your boiler, and is often required to keep your manufacturer's warranty valid.
What is a Landlord Gas Safety Certificate (CP12) and do I need one?
A Landlord Gas Safety Certificate, or CP12, is a legal requirement for anyone renting out a property with gas appliances. It documents a series of checks carried out by a Gas Safe engineer to ensure all gas appliances, pipes, and flues are safe for your tenants to use. This check must be completed every 12 months.
What are the signs that I might need a new boiler?
Common signs include your boiler frequently breaking down, your energy bills creeping up, the boiler making unusual noises (like gurgling or clunking), or if it's becoming difficult to find replacement parts. If your boiler is over 10-15 years old, a new, more efficient model could save you significant money in the long run.
What is a system conversion?
A system conversion involves changing the type of heating system you have, most commonly from an older conventional system (with a separate hot water tank) to a modern, high-efficiency combi boiler. This frees up space by removing the need for a tank and provides instant hot water on demand.
What is powerflushing and how does it benefit my heating system?
Powerflushing is a process that uses a high-velocity, low-pressure jet of water to clean the sludge, rust, and debris that builds up inside your central heating system over time. The benefits include more efficient radiators, faster heat-up times, reduced boiler noise, and a longer lifespan for the entire system.
Can you install smart heating controls like Hive or Nest?
Yes, absolutely. We can install a range of smart thermostats, including those from leading brands like Hive and Nest. These controls allow you to manage your heating and hot water remotely from your smartphone, helping you improve efficiency and lower your energy bills.
