I can not rate Walsh Plumbing highly enough. From start to finish the service was smooth, quick and professional. Sales, pricing, fitting, after sales service - all faultless. Such a relief to have had my boiler replaced so quickly and smoothly. Thank you

Fitted in new boiler and took old very large barrel shaped one away! Professional, very good rate and even brought their own hoover and cleaned up after themselves. I would highly recommend

Used Walsh Plumbing to replace my boiler which packed up. They came out literally 2 hours after my boiler stopped working, and 1.5 days later they had installed a new one. Great communication and service I would highly recommend.

Fantastic service. Visited same day to quote and talked us through numerous options. Quick turnover from deciding which option to go with to getting an installation booked. The engineer carrying out the boiler install was very professional, tidy and kept us informed of his progress throughout. Would highly recommend.

I have recently used Walsh plumbing for a service of my boiler and fitting of two new radiators- I couldn’t fault them one bit! Their professionalism throughout was top notch & they were tidy and polite from start to finish. We also provide them with scaffolding when required (just scaffolding Hertfordshire LTD)
