Which rules apply in the South East?

Replacement windows, heating systems and some electrical work are controlled under the Building Regulations. In higher-risk buildings (18 metres or 7 storeys and above, with two or more homes), building work needs Building Safety Regulator approval before it starts unless it is exempt. Most repairs and like-for-like replacements are exempt, but heating systems, fuse boxes and glazing units are not.

What does it cost in the South East?

Our guide range for whole-house retrofit towards EPC C in the South East is £14,850–£25,950 per home. That is the UK range of £13,500–£23,600 (published figure) adjusted by a regional cost factor of 1.10 (VOA Rating Cost Guide 2026: 1.05–1.15); figures are before VAT where the source states it. Every job is priced after survey; specification, access and the condition of the homes will move the figure.

How do we deliver it?

We do not treat a measure in isolation. If the design adds insulation and airtightness, we make sure the ventilation upgrade is in the same programme, because condensation is the most common retrofit failure.
