Services
Boiler Installation
We specialise in installing high-efficiency central heating boilers from leading brands including Vaillant, Worcester Bosch, and Baxi Potterton. Our engineers assess your property's requirements to recommend either combination or system boilers with appropriate hot water storage solutions. All installations include pipe routing, control system integration, and final safety testing to ensure optimal performance and compliance with Gas Safe standards.
Central Heating Repairs
Our emergency repair service addresses boiler breakdowns, radiator leaks, and system inefficiencies with rapid response times. Engineers diagnose faults using professional diagnostic tools, provide clear cost estimates before work begins, and aim to complete repairs within 24 hours when parts are required. We service all boiler types including combi, system, and conventional models.
Gas Safety Checks
We conduct annual Gas Safe compliance checks for boilers, water heaters, and gas fires to ensure safe operation. Our inspections include combustion analysis, flue gas testing, and component integrity assessments. We provide detailed safety certificates and recommend necessary maintenance to improve system efficiency and prolong appliance lifespan.
Powerflushing
This service removes sludge and limescale buildup from central heating systems using high-velocity chemical flushing. We target circulation pumps, heat exchangers, and radiators to restore system efficiency and prevent future breakdowns. The process includes inhibitor treatment to reduce future corrosion and maintain optimal heat transfer performance.
Emergency Plumbing
Available 24 hours a day, our emergency service addresses burst pipes, complete heating failures, and urgent gas leaks. We prioritise vulnerable households with young children or elderly residents during winter months. Our engineers carry essential spare parts and diagnostic equipment to resolve most issues immediately upon site visit.

Replaced a broken and leaking boiler for us at short notice (a Saturday) and did a great job including fixing a leaking pipe he found for no extra.

Within 90 minutes of telephoning the company he was at my property looking at my boiler. The prediction of the problem which I described on the telephone was accurate. I have used this company to service my boiler in the past and I totally trust them and highly recommend them.
