External wall insulation makes the biggest difference on solid-wall, pre-cavity housing wherever it sits in our coverage area — Waverley, Guildford, Woking, Surrey Heath, Elmbridge and Epsom & Ewell districts all have older streets where this applies, alongside the newer estates in our Hampshire and Berkshire towns that were simply built to lower thermal standards than today's regulations.
Planning considerations vary by district — each borough runs its own conservation areas and Article 4 directions — so if you're not sure which of our individual town pages covers your address, this page is the right starting point for the postcode and planning detail specific to it, or call us directly and we'll place you in seconds.
