Why TW is well-placed for heat pumps
- Strong fundamentals with modern heat pumps now viable across most housing types.
- House-heavy stock simplifies outdoor-unit siting and emitter upgrades.
- Moderate solar yield lets PV offset a chunk of electricity use.
Tip: pair a heat pump with basic draught-proofing and TRV balancing to raise system COP before thinking about bigger works.
Planning & noise at a glance
Most single domestic installations are permitted development if they meet volume & noise rules. Always confirm site specifics on your district page when you start a quote.
- Keep clearances to boundaries/windows; respect noise guidance at the nearest habitable window.
- One outdoor unit per property under PD (additional units often need permission).
