Can I add an extra bathroom to my London home?

Can I Add an Extra Bathroom to My London Home?

Yes — adding a bathroom to a London property is one of the most common projects our engineers work on, particularly for loft conversions, basement extensions and bedroom reconfiguration.

What's Involved

Plumbing connections — the new bathroom needs hot and cold water supply, waste drainage and potentially ventilation pipework.

Water pressure assessment — before adding another bathroom, we assess whether your current system can support it. A combi boiler supplying 3+ bathrooms will likely need upgrading to a system boiler with Megaflo.

Building regulations — new bathrooms require Building Control notification. We can advise on what's required.

Considerations for London Properties

• Georgian and Victorian properties — original pipework may need replacement
• Pressure — many central London properties have lower mains pressure; unvented cylinders solve this
• Access — older London properties can have complex pipework routes
• Party walls — new drainage may require party wall notification

Cost Estimate

Adding a new bathroom with basic fixtures: £4,500–£12,000 for plumbing work (excluding fixtures, tiles and fit-out).
