MEES Regulations

Minimum Energy Efficiency Standards (MEES) require rental properties to have an EPC rating of at least E. The government has proposed increasing this to C by 2028.

  • • Current requirement: EPC E or above for rentals
  • • Proposed 2028: EPC C for new tenancies
  • • Non-compliance: up to £30,000 fine
  • • Spending cap: £3,500 (current rules)

About the EPC Upgrade Calculator

What it does and how it helps you

The EPC Upgrade Calculator helps UK property owners and landlords calculate the cost to improve their Energy Performance Certificate (EPC) rating. Plan upgrades to meet MEES regulations, reduce energy bills, and increase property value. Select from a range of energy efficiency measures and see projected costs, SAP improvements, and payback periods.

14 different energy efficiency measures with accurate UK costs
SAP point improvements for each upgrade measure
Grant funding calculator (ECO4, BUS, local schemes)
Payback period analysis based on energy bill savings

How It Works

Understanding the calculation method

The calculator works by: 1. Starting Rating - Select your current EPC band (A-G) based on your existing certificate 2. Target Rating - Choose the rating you need to achieve (typically C for MEES compliance) 3. Select Measures - Pick from 14 different energy efficiency improvements 4. Cost Estimation - See realistic costs with low/high estimates and regional variations 5. SAP Analysis - Understand how each measure improves your SAP score 6. Grant Funding - Factor in available grants like ECO4 and Boiler Upgrade Scheme 7. Payback Period - Calculate when energy savings will recover your investment Each upgrade measure shows its SAP point improvement and typical cost range. The calculator accounts for your property type, age, and location to provide accurate estimates.

When to use this calculator

Use this calculator when planning EPC upgrades for rental properties (MEES compliance requires minimum EPC E, with EPC C proposed for 2028), preparing a property for sale, or planning energy efficiency improvements. Essential for landlords facing MEES regulations or property investors buying below-EPC-C properties.

Frequently Asked Questions

Common questions about this calculator

Under current MEES regulations, rental properties must have a minimum EPC rating of E. The government has proposed raising this to EPC C for new tenancies by 2028, though the timeline is under review. Landlords who don't comply can face fines of up to £30,000. There's currently a £3,500 spending cap per property.
The most cost-effective measures are typically: LED lighting throughout (£200-500, +3 SAP points), draught proofing (£150-400, +2 points), loft insulation to 300mm (£300-600, +8 points), and cavity wall insulation (£800-1,500, +10 points). Always start with insulation and draught-proofing before upgrading heating systems.
Yes, several schemes are available: ECO4 provides free or subsidised insulation for eligible households, the Boiler Upgrade Scheme offers £7,500 towards air source heat pumps, and many local authorities run their own grant schemes. Check with your local council and energy suppliers for available funding.
For a typical 3-bed semi-detached house, upgrading from E to C costs between £5,000-£15,000 depending on the property's starting condition and required measures. This usually includes loft and cavity wall insulation, a new condensing boiler, double glazing, and smart heating controls. Properties requiring solid wall insulation or heat pumps will cost more.
SAP (Standard Assessment Procedure) is the UK government's energy rating calculation method. It produces a score from 1-100, which translates to EPC bands: A (92+), B (81-91), C (69-80), D (55-68), E (39-54), F (21-38), G (1-20). Each energy efficiency measure adds SAP points. You need approximately 69 SAP points to achieve EPC C.
