Funding in 2026

What help can you get in Wales?

Grants, loans and tax breaks for solar — but not every scheme applies to every household.

Free improvements

Warm Homes Nest

Welsh Government scheme offering free energy advice and, for qualifying low-income households, free solar panels, insulation and heat pumps.

ECO4

UK scheme that funds efficiency improvements for low-income and vulnerable households. Solar PV can be included as part of a wider package.

Until 31 Mar 2027

0% VAT

Residential solar currently attracts 0% VAT, including panels, inverter, battery if fitted at the same time, scaffolding and labour.

Get paid for surplus

Smart Export Guarantee

Interest-free loan

Green Homes Wales

Welsh Government interest-free loans from £1,000 to £25,000 for energy-efficiency improvements, including solar panels.

Who qualifies?

Free solar is targeted support

Free or fully funded solar is most likely if you:

  • Live in Wales
  • Own your home or rent privately with landlord consent
  • Receive a means-tested benefit such as Universal Credit, Pension Credit or Housing Benefit
  • Have an EPC rating of E or below (or D or below with a qualifying health condition)
  • Have a roof suitable for solar — south-facing or east/west, unshaded and structurally sound
Is it worth it?

West Wales has good solar potential

A well-sited 4kW system in Ceredigion or Carmarthenshire will generate more over a year than the same system in much of northern England. The key factors are:

Daytime usage

Solar saves most when you use power as it is generated.

Battery storage

Store surplus daytime generation for evening use and avoid low SEG export rates.

Roof orientation

South-facing unshaded roofs are ideal; east-west roofs can still work well.

Staying put?

Payback matters less if you sell soon; MCS certification adds saleability.

Honest cost context

Industry guides in 2026 quote a typical 4kW residential system at roughly £5,500–£8,000 before the 0% VAT saving. We do not publish fixed MGC prices because every roof is different. We survey first, then price.

Domestic vs commercial

Which fits your property?

Solar works for homes, farms, workshops, schools and small industrial units — but the business case differs.

Domestic solar

Most West Wales homes suit a 3–6kW roof-mounted system. Benefit from 0% VAT, SEG payments, permitted development in most cases, and short payback from offsetting domestic electricity rates.

Commercial solar

Typically 10kW up to several hundred kW. We handle DNO applications and three-phase connection checks. Ideal for farms, workshops, holiday lets and industrial units with daytime demand.

Why MCS certification matters

MCS — the Microgeneration Certification Scheme — is not a legal requirement, but it is a practical one.

  • SEG payments require an MCS-certified installation.
  • Some grant schemes require MCS certification to qualify.
  • Resale is easier — a buyer's solicitor can verify the system.
  • The workmanship is audited against technical and consumer standards.

MGC West Wales is MCS-certified for solar PV. We provide the MCS certificate and help register you for SEG once the system is commissioned.

Our process

What happens before we quote

We do not sell systems over the phone. We check five things before recommending anything.

01

Roof survey

Orientation, pitch, shading, condition and available area.

02

Structural check

Can the roof take the load, or is reinforcement needed?

03

Electrical survey

Consumer unit capacity, earthing and export-capable smart meter.

04

Usage profile

Your last 12 months of bills show what size system makes sense.

05

DNO check

We notify your Distribution Network Operator before connection.

FAQ

Solar panels, grants and payback in Wales

Answers to the questions homeowners ask most often.

Who qualifies for free solar panels in Wales?
Free solar is most likely through the Welsh Government's Nest scheme or the UK-wide ECO4 scheme. You usually need to own your home or rent privately with landlord consent, be on a low income or receive a means-tested benefit, and have a property with an EPC rating of E or below (or D or below with a qualifying health condition).
Are there solar grants available in Wales for 2026?
Yes. Nest provides free improvements for eligible low-income households. ECO4 funds efficiency work including solar for qualifying households until 31 December 2026. Green Homes Wales offers interest-free loans from £1,000 to £25,000 for homeowners. All homeowners also benefit from 0% VAT on residential solar until 31 March 2027.
Is it worth getting solar panels in Wales?
For many West Wales homes, yes — particularly if you use electricity during the day, have an unshaded south-facing roof, and plan to stay in the property long enough to see the payback. Wales receives enough annual sunshine for well-sited systems to perform strongly.
How much does it cost to install solar panels in Wales?
A typical domestic 4kW system is quoted in industry guides at roughly £5,500–£8,000 in 2026, before the 0% VAT saving. The actual cost depends on roof type, system size, access, inverter choice and whether you add a battery. MGC provides a fixed written quote after a roof survey.
Is there a grant in Wales for solar panels?
Yes, but most are targeted rather than universal. Nest and ECO4 are aimed at low-income and vulnerable households. Green Homes Wales is an interest-free loan open to any Welsh homeowner. All residential installations currently pay 0% VAT until 31 March 2027.
What is the average price to have solar panels fitted?
Industry averages vary widely. For context, a 3–4kW domestic system is commonly quoted between £5,500 and £8,000, while a 5–6kW system is typically higher. Commercial systems are priced per kW and depend on roof size, structural requirements and grid connection. The only reliable figure is the one based on your roof survey.
What is MCS certification and do I need it?
MCS (Microgeneration Certification Scheme) is a quality assurance scheme for installers and products. You need an MCS-certified installation to claim the Smart Export Guarantee and to satisfy many grant schemes. It also makes the system easier to sell later.
