Frequently Asked Questions

Common questions about our plumbing.

Who carries out gas work on your projects?
Gas work is never carried out by Leeway Brothers directly — we're not Gas Safe registered ourselves. We bring in independent Gas Safe registered businesses, who work under their own registration, show you their Gas Safe ID card and issue the certificates for their work. We'll give you their details before work starts so you can check them at gassaferegister.co.uk.
How much does a new boiler cost?
A new boiler installation typically costs between £1,800 and £3,500 including fitting. The price depends on the boiler type (combi, system, or regular), brand, and complexity of installation. We offer free quotes to give you an accurate price.
How quickly can you attend a plumbing issue?
For planned work, we can usually schedule within 1–2 weeks. For urgent issues affecting existing customers, we aim to respond within 24–48 hours. Contact us to discuss your timeframe.
Do you offer a guarantee on plumbing work?
Yes, all our plumbing work is guaranteed. Additionally, boiler installations come with manufacturer warranties of up to 12 years depending on the brand and model chosen.
Can you install underfloor heating?
Yes, we install both wet and electric underfloor heating systems. Wet systems are ideal for new builds and extensions, while electric systems suit smaller areas and renovations. We'll recommend the best option for your project.
