How to Improve Your EPC Rating in Hackney | Practical Guide

If your Hackney property has a low EPC rating — particularly an F or G — you face a real problem. You cannot legally let it, your energy bills are higher than they need to be, and the value of your property may be affected. The good news is that most Hackney properties can be moved up one or two rating bands with targeted, affordable improvements.

Why Hackney Properties Often Have Low EPC Ratings

Hackney has a large proportion of Victorian and Edwardian housing stock — terraced houses, converted flats, and mansion blocks built before modern insulation standards existed. These properties typically have solid brick walls with no cavity, single-glazed or poorly sealed sash windows, older gas boilers, and minimal loft insulation. These are the main reasons so many Hackney properties are rated D, E or below.

The Improvements That Make the Biggest Difference

1. Loft Insulation

Rating impact: High  |  Typical cost: £300–£600

If your loft is accessible and currently uninsulated — or has less than 100mm — adding 270mm of mineral wool insulation is one of the fastest and most cost-effective improvements available. In properties where heat loss through the roof is significant, this alone can push a property from an E to a D.

2. Boiler Upgrade

Rating impact: High  |  Typical cost: £2,000–£3,500 installed

Replacing a G-rated or old gas boiler with a modern A-rated condensing boiler can add 5–10 SAP points to your score. If the boiler is more than 15 years old, this is usually the single biggest improvement available.

3. Heating Controls

Rating impact: Medium  |  Typical cost: £150–£400

Adding a programmer, room thermostat and thermostatic radiator valves (TRVs) adds measurable SAP points at low cost. Smart thermostats such as Nest or Hive are recognised in the SAP calculation.

4. Cavity Wall Insulation

Rating impact: High (where applicable)  |  Typical cost: £500–£1,500

Many inter-war and post-war Hackney properties have cavity walls that can be insulated. This only applies where a cavity exists — a Victorian solid brick wall cannot be cavity-insulated. Your EPC assessor can confirm which applies to your property.

5. Internal Wall Insulation (Solid Walls)

Rating impact: Very high  |  Typical cost: £5,000–£15,000

For solid-walled Victorian terraces — the most common property type in Hackney — internal wall insulation (IWI) is the most impactful but most disruptive option. It involves lining internal walls with insulated plasterboard, dramatically improving thermal performance and potentially pushing a property from an F or G up to a D or C.

6. Double or Secondary Glazing

Rating impact: Low to medium  |  Typical cost: £300–£6,000

Replacing single-glazed windows adds SAP points, but the impact is smaller than insulation or heating upgrades. Secondary glazing is a cheaper option and may be preferred in Hackney conservation areas where full window replacement is restricted.

What EPC Rating Do You Need in Hackney?

Under MEES, all privately rented properties in England must have an EPC rating of E or above. Hackney also operates an Additional HMO Licensing scheme — all HMO licensing applications require a valid EPC rated E or above. If your property is currently rated F or G, you must carry out improvement works before letting and obtain a new EPC to evidence the improved rating.

Frequently Asked Questions

How much does it cost to improve an EPC rating from F to E in Hackney?

For a typical Hackney Victorian flat, loft insulation plus heating controls can cost £500–£1,000 and may be sufficient to move from F to E. For solid-walled properties, more significant works may be required.

Can I get a grant to improve my EPC rating?

The Great British Insulation Scheme and the Boiler Upgrade Scheme offer funding for some measures. Eligibility depends on your property type, EPC rating and household income.

Do I need planning permission to improve my EPC rating?

Most internal improvements do not require planning permission. However, properties in Hackney’s conservation areas may have restrictions on external works and window replacement. Check with Hackney Council before proceeding with external changes.

How long does an EPC last after improvement works?

A new EPC is valid for 10 years from the date of issue.
