Posted on Jan-PhilipTrustindex verifies that the original source of the review is Google. Amazing service! Replaced my boiler , very professional team.Posted on Liz BullTrustindex verifies that the original source of the review is Google. Amazing quick response to doing a quick fix on the boiler and then replacing it , all within a few days when the temperature was freezing a few days before Christmas . Wonderful team, professional and speedy. Highly recommended .Posted on Adrian G WealTrustindex verifies that the original source of the review is Google. MONDAY - The water pressure over the weekend was dropping fast and I was refilling twice a day. We called out Corvee who have looked after us for many years. WITHIN 2 HOURS - Corvee were checking the boiler. The heat exchanger had gone! The Boiler whilst very good (and fitted by Corvee) was nearly 20 years old. So a new one was sensible. TUESDAY - E-mail estimate arrived. The price was right so was accepted. FRIDAY - (all in the same week) the new boiler was fitted with no issues or problems. WHAT A KETTERING BASED COMPANY TO BE PROUD OF!Posted on Trevor HaynesTrustindex verifies that the original source of the review is Google. Another successful outcome. As ever, response from Corvee was excellent and an intermittent fault with our heating system was quickly resolved by replacing the original 26-year old timer. All completed by the Corvee team in a professional and dependable way.Posted on Christine PuttTrustindex verifies that the original source of the review is Google.

Corvee's engineer Sahal attended & serviced my boiler, he was polite & friendly, was very tidy, careful & respectful of my property & did a thorough job. Very professional, I'm very pleased. I don't really like having strangers in my house but needs must, & for anyone else who worries about that, DONT. use corvee... I also now have corvee to do the boiler service & landlord cert at my rental property, in Jan 2025, the service engineer at that time was also very polite, thorough & tidy. So this is not a one off. We'll done Corvee.Posted on Roger GriggsTrustindex verifies that the original source of the review is Google.

FAQ
Frequently Asked Questions About Boilers
Corvee Property Services is your trusted partner for boiler installations and repairs across Northamptonshire, ensuring top-tier satisfaction.
How much does a commercial boiler installation cost?
Costs vary significantly based on output, cascade configuration, flue routing and plant room complexity. Typical range for commercial replacements: £8,000 to £80,000+. We provide detailed, itemised quotes following a no-obligation site survey.
Do you service commercial boiler plant rooms?
Yes. We service plant rooms with multiple boilers, cascade configurations, low-loss headers, pumps, pressurisation units and BMS integration. Annual servicing aligned to SFG20 and manufacturer requirements.
What is the difference between CP12 and CP17?
CP12 is the domestic landlord gas safety certificate. CP17 is the non-domestic (commercial) gas safety record covering commercial gas appliances, pipework and ventilation. Commercial premises require CP17 annually to satisfy the Gas Safety (Installation and Use) Regulations.
How often should commercial boilers be serviced?
Commercial boilers require annual servicing at minimum, with higher-output or cascade plant often on 6-monthly or quarterly schedules aligned to SFG20. Annual servicing preserves manufacturer warranties and is usually required for building insurance.
Do you install Worcester Bosch Commercial boilers?
Yes, we are a Worcester Bosch Commercial Accredited Installer. This authorises us to extend manufacturer warranties on qualifying installations. We also install Vaillant, Remeha and Hamworthy commercial boilers.
