Gas & Electric Certificates: Are They Needed When Selling a House?

No. Neither a gas safety certificate nor an electrical safety report is legally required to sell a house in England or Wales. The only certificate you must have is a valid EPC.

Three things change that answer:

• you are a landlord or selling with a tenant in situ

• work has been done since 2005 that needed Building Regulations sign-off

• your buyer’s solicitor or their lender makes it a condition

We buy houses for cash and resell them through agents, so I see this paperwork from both sides. The certificate is almost never what costs a seller money. The form you sign and the survey your buyer commissions are.

What you legally need, and what you don’t

Nothing in law says you may not sell a house without a given certificate. The duty to certify attaches to the work being carried out, not to the act of selling.

So if the law is quiet, why does the question keep landing? Nine times out of ten, a survey put it there.

Why buyers keep asking: the survey, and the quote that follows

Almost everyone asking this question got here the same way: a survey came back recommending a gas and electrical test.

Every single surveyor will tell you to get the gas and electrics tested, because they are not qualified to inspect either and the recommendation covers them.

It is a disclaimer, not a diagnosis. A homebuyer survey will not confirm your boiler works or your wiring is sound.

Then the buyer commissions a specialist, the specialist quotes, and the quote arrives on your desk as a price reduction demand dressed up as objective cost.

The £15,000 quote that was really a £2,000 job

We had one instance where the buyer’s quote said £15,000 for a rewire, and they wanted that off the price.

We asked a registered electrician we know to quote for the same work. Two thousand pounds.

We negotiated a reduction on that realistic figure instead, which let the buyer do the work after completion. One phone call was worth £13,000.

So never treat the buyer’s quote as the cost of the work. Get your own from a registered engineer or electrician before you concede a penny. And a reduction that lets the buyer do the work after completion beats scrambling to certify remedial work before exchange.

For a sense of proportion, here is what the checks themselves cost:

• a gas safety check is around £80, up to £120 with several appliances

• an EICR is £100 to £350, with £150 to £250 typical for a three-bedroom house

• an EPC is £45 to £120, with £60 to £80 typical

Prices vary by area.

The form that actually catches sellers out: TA6 Section 11

The law does not ask you for a gas certificate. The TA6 asks you what you know, and that is where the liability sits.

Every seller completes and signs the TA6 Property Information Form. The 6th edition, in use from 30 March 2026, has fifteen sections, and Section 11, Services, is where gas and electrics get declared.

It asks about:

• electrical work since 1 January 2005 and whether you hold the certificate

• whether there is an EICR

• the heating system with its installation certificates and most recent inspection report

Buyers are entitled to rely on those answers. The Law Society is blunt about the consequence: a buyer who has been misled can claim compensation after completion.

“Not known” is a safe answer where something genuinely is not known. Guessing is not. Ticking that a certificate exists when you have never seen it is how a non-obligation becomes a live liability.

So dig out your installation paperwork before the form lands, not after.

Do you need an electrical certificate to sell?

No. The Law Society states it plainly: an EICR is not a legal requirement for the sale of property in England and Wales.

You will still find articles on major property portals claiming it is illegal to sell without an Electrical Installation Certificate. It is not.

What matters is when the work was done. Since 1 January 2005, electrical installation work in a home has had to comply with Building Regulations Part P and the BS 7671 wiring standard.

Notifiable work includes new circuits, a replacement consumer unit, garden and outbuilding wiring, alterations to a bathroom circuit and EV charge points. It has to be certified by the installing electrician as a registered competent person, or signed off by Local Authority Building Control.

So you are looking for the EIC or Minor Works Certificate the installer issued, or the Building Regulations Compliance Certificate proving the work was notified. An EICR is different: a snapshot of condition today, which cannot retrospectively certify old work but is frequently what a buyer’s solicitor accepts.

Both gas and electrical work should produce a certificate. The real question is whether anything has been done to this house since 2005 that needed one, and where that paperwork went.

Do you need a gas safety certificate to sell?

No, not as an owner-occupier. Gas Safe Register is clear that the only gas document the law requires is the Landlord Gas Safety Record.

Two documents get confused here, and only one travels with the house. A Gas Safety Record checks the appliances as they stand today. A Building Regulations Compliance Certificate proves the installation was notified to the local authority, and that is the one the new owner receives. Boilers fitted on or after 1 April 2005 needed that, or a Building Control completion certificate.

Lost yours? A duplicate from Gas Safe Register costs under £10 including VAT. Check their site for the current fee.

If you hold nothing and you are an owner-occupier, legally nothing happens. No fine, no block on the sale. In practice you get a solicitor’s enquiry, then a buyer-commissioned inspection, then a price conversation at the worst possible moment.

Only a Gas Safe registered engineer may legally work on gas, and your duty to keep the appliances safe does not vanish just because no certificate exists. On a house that had been lived in by an owner-occupier for fifteen years with a boiler nobody had touched, I would spend the £80 anyway.

That is the owner-occupier position. Put a tenant in the same house and the certificate stops being a choice.

When they are compulsory: tenanted and recently let property

For landlords the answer flips. Both certificates are legally required for as long as the tenancy runs, and that includes every week of the sale.

• Gas: an annual Landlord Gas Safety Record from a Gas Safe registered engineer, with a copy to existing tenants within 28 days of the check and to new tenants before they move in.

• Electrics in England: the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020 require the fixed installation to be inspected and tested at least every five years while the property is let. Councils can impose penalties of up to £30,000 per breach.

• Electrics in Wales: since 1 December 2022, fitness requirements under the Renting Homes (Wales) Act 2016 have meant every rented home needs an EICR, re-inspected at least every five years.

If we are buying from an individual, particularly a landlord, we expect satisfactory reports for both gas and electric. If they cannot be provided we may carry out our own checks, and depending on the outcome it is reflected in the price offered.

An investor buyer’s solicitor raises the same enquiries. This paperwork is optional in an owner-occupier sale. In a landlord sale it is not.

The paperwork is missing: four routes, and you pick one

Missing certificates rarely stop a sale. What matters is picking the route the buyer’s solicitor will accept.

• Re-order the original. That duplicate covers a boiler notified by a Gas Safe engineer. For electrics, ask the original installer to certify retrospectively, and check whether the council or the installer’s scheme holds a copy.

• Regularisation. Apply to your local authority’s Building Control for a regularisation certificate covering unauthorised past work. It is the proper fix and it removes the problem permanently. Use a good local solicitor rather than a nationwide firm: a local one knows what its own Building Control accepts, and a slow conveyancer can kill a deal.

• Indemnity insurance, plus a test. Say a boiler was fitted in 2019 with no installation certificate. You can insure the missing paperwork, but you would still want the installation tested: indemnity covers the legal consequence, not the physical condition. And applying for regularisation, or even ringing the council, normally destroys your ability to get cover. Pick one route, not both.

• Evidence the condition instead. An EICR cannot retrospectively certify old work, because only the installing electrician can issue an EIC, but it shows the installation is safe today, and that is often what a buyer’s solicitor settles for.

And do not start remedial gas or electrical work you cannot get certified before exchange. Half-finished, uncertified work is worse than none.

Which route you need also depends on who is buying. Take a mortgage lender out of the deal and some of these questions never get asked.

Selling for cash removes the lender, not the condition question

The EPC still applies, whoever is buying.

What changes is the lender. No mortgage means no lender-driven condition on Part P sign-off or FENSA certificates and no valuation to fail, so missing paperwork gets priced rather than becoming a condition of exchange. An uncertified loft conversion that a cautious lender treats as a dealbreaker does not stop us buying.

What does not change is condition. Bring what you have: being upfront gets you a firmer offer than being vague.

This matters most when the paperwork has already become a chain problem: a condemned appliance eight weeks in, a failed EICR, or a tenanted property you need out of. We make a cash offer within 24 hours, can exchange in as little as 48 hours and complete in around 28 days, and we cover your conveyancing fees if you use our recommended solicitor. Call 020 8634 0224.

The trade-off is honest enough: we buy below market value, typically 75 to 85%, so you are buying speed and certainty rather than the last few per cent of price. With months in hand and no chain pressure, sorting the paperwork out and selling through an agent will beat us. Eight weeks into a chain with a buyer holding a £15,000 quote, speed is usually worth more.
